Sandybridge Overclocking Guide Part 1 of 2

[purplehatcult]

The Auto Tune function of the ASUS Smart Suite II would overclock this set up to 4.4GHz with out hassle and, with a cooling system like that, would have no problem reaching 5GHz

[ReconTechTips]

Good God...Sweet Set Up!

[LINKTheReaper]

lol you correct yourself the whole video!

[SingularityComputers]

@LINKTheReaper What are you referring to.

[MrRyaNSays]

Holy cows

[halliwuud]

what do you run Linx Settings at, what problem load and what MiB?

[SingularityComputers]

@halliwuud I do 5 runs initially using all my memory and leave the rest of the settings at defaults. Then I do 20 runs once I find reasonably stable settings. After that I just use the system normally and if there is still instability I just keep adjusting settings till its stable. But usually 20 runs means 100% stable every time.

[hcbleach]

I run my ram at 1.65v (as suggested from kingston) but is the ram voltage too high for daily use?

[mrPKboy15]

Ok I have a question I over clocked my same CPU and am running LinX and the same temp thing you have but version just a little older by like .03 or something anyway I so far have the voltage down to 1.32 from 1.4 where you started and have gotten no blue screen am over clocked to 4.6 btw not 4.4 I'm not the best with computers want to get better am only 15 so ya but anyway my question is should I keep going? Getting .08v lower then in you vid seems like its to much lower somehow I'm not overhea

[xRevelations1]

What is the highest overclock and Volts you would go for a safe 24/7 oc without highly damaging your cpu . Atm im on 1.35V for 4.5ghz (maybe more volts than i need)

[CoolyHaloGmr29528]

don't let the temps go above 85 degrees Celsius of Fahrenheit?

[SingularityComputers]

@CoolyHaloGmr29528 Celsius.

[CoolyHaloGmr29528]

@SingularityComputers Oh God is that good to hear, lol

[halliwuud]

Thank you very much for the information you have been very helpful, and i also saw the testing you did with the assist fan cause im going watercooling as well, Getting a 50mm fan today.

The reason i asked if BIOS needs to be updated is that ive read some nasty things about BIOS updates going wrong and crashing you whole system. Thats why i asked. Did you update you sabertooth via internet through Asus Suite II or did you flash it?

[SingularityComputers]

@halliwuud Put the BIOS on a flash drive and flash it from the EZ Flash utility in the BIOS. It is true that on single BIOS motherboards you can potentially corrupt the BIOS which means a mobo replacement in most cases. The thing is it only takes about 10 seconds so as long as the power doesn't go off or something in that time, then its fine.

[halliwuud]

One last thing before i give a go at this. Do you have to adjust your RAM for the overclock to work or is that not a requirment? And do you have to upgrade bios before overclocking with the sabertooth?

[SingularityComputers]

@halliwuud You dont have to adjust the memory settings, but I would recommend it. Just manually set your memory to its specifications. I do recommend updating the BIOS, it may improve stability and performance.

[halliwuud]

Do you think its possible to run for 4,6ghz with the same settings on your tutorial since 1.4v seems pretty high for 4,4ghz. This is my rig.

nVidia GeForce GTX590 3072MB

Intel Core I7 2600K 3.4GHz

Asus Sabertooth P67 - Sandy Bridge

Kingston HyperX 16GB DDR3 1600MHz

Seagate 1000GB 7200RPM 32MB

OCZ Solid Series 3 120GB - 500 MB/550 MB/sek (SSD)

[SingularityComputers]

@halliwuud My settings are just basic guidelines. Like I explained in the video, the whole basis of overclocking is stability testing. You need to get the voltage down as low as you can for the frequency that you are running. 1.4V 4.4GHz is just the start and from there you can up the frequency more or down the voltage.

[SPAZZY1912]

i read a few things that when you overclock you disable turbo? can someone clear that up for me? i don't understand.

[SingularityComputers]

@SPAZZY1912 It depends on the platform. On X58 its far better to disable Turbo, SS, C1E and all that. Sandybridge is different, its designed to be far more simple. I mean all you really need to do now is change 2 settings instead of about 15 like with X58. Its been dumbed right down.

[SPAZZY1912]

@SingularityComputers

oh alright, thanks for clearing that up for me (:

[uuuserunknown]

I just want to OC my i7-2700k to 3.8Ghz. Do i need to change the voltages?

[zIceCoLD]

And is 460 sli working good?

[zIceCoLD]

I cant change the turbo ratio what do i do?

[Sourcecode01]

dude! total over the top with the colling system eh?

[eviltuna1912]

Is that a custom open case? That's just SICK!!!

[Chick3nFingDing]

@eviltuna1912 Danger Den Torture Rack.

[MrRockoutLoud]

i have the same processor with an aircooling HAF 212+. would i be able to have it be stable by changing ONLY the turbo ratio to 40 or something? this is my first time overclocking and i really need some help with this

[HERPDEDERP49]

this is perfect i ahve the exact same hardware setup as he does and i want to go to the exact same things

[Fiddyismyway]

HOW DO YOU OPEN THE MENU????

[azorulz]

can someone tell me if i can hit about a 4.3GHz OC on an i5 2500k with a Hyper 212 EVO cooler?

[Level84]

@azorulz yes u can, I have a hyper 212+ and got my 2500k up to 4.5ghz

[tecinfolucas]

@Level84 what voltages at 4.5? I'm trying to get it stable at 1.325 but the vdroop fucks the voltage and it goes to (LLC set to very high) 1.308.. after 1 hour of prime the system freezes :( so I'm using right now 4.4 because I'm afraid of pushing more than 1.35V

[Level84]

@tecinfolucas Are you using offset? I have mine offset +.030 and runs stable at about 1.290V. I'd be shocked if you can't get 4.5 with 1.325 still...

[tecinfolucas]

@Level84 Tried right now with offset +.030, LCC very high, PLL enabled, phase extreme, VRM 350Khz, cpu cabability is 100%, everything else is auto.. aaaand the load voltage is 1.376V :(

[Level84]

@tecinfolucas What motherboard? Also do not set cpu vcore to auto, set it to manual with an offset of +.030. Auto always sends WAY too high voltages.

[tecinfolucas]

@Level84 Something strange happened I tried -0.005 Offset Vcore, LCC on HIGH, and PLL Overvoltage to AUTO, and bang! my chip passed the intelburn test with 1.304V under load WTH??!

[Level84]

@tecinfolucas Hm and you're sure you set CPU Voltage to Manual Offset Mode correct? Because it sounds like it's on an auto OC voltage... That is the only way it would make sense for a negative Offset to send OVER stock voltage to an overclocked CPU and have it work lol.

[tecinfolucas]

@Level84 Yes I am sure.. I think I found my sweetspot with 4.5Ghz offset at +0.010 and Vcore fluctuating between 1.320~1.328 in full load, kind of a pain to understand this offset mode..

[tecinfolucas]

@Level84 Hmm I setted -0.05 Offset Vcore and the voltage between load is 1.344V but i dont know if it is stable yet I'm running prime right now. Btw my motherboard is P8Z68-V PRO, I have the settings: LLC=ULTRAHIGH CurrentCapability=100% VRM Frequency=350Khz Phase Control= Extreme and Duty=T.Probe, BLCK always 100.0, I dont know why my chip is pulling so much voltage to be stable :(

[chucko83]

are you in a kitchen at a restaurant?

[IMxLEGITxBEAST]

Can I reach 4.8Ghz with my i5 2500k with a Corsair H100 Liquid Cooler?

[cucapicham]

I oc'ed my 2600k to 4,7 Ghz just by changing the multiplier.

[blackspringer1]

When is part 2 coming

[SingularityComputers]

@blackspringer1 Its on my channel.

[blackspringer1]

Great vid. How much memory are you using?

[EvilMonkeyAvenger]

To achieve lets say.... 4.00GHz on the i7 2600k do you only change the multiplier?

[Falcrist]

@EvilMonkeyAvenger Like he said in the video, you don't have to mess with the base clock. To be honest, you might not even have to bump the voltage to get 4ghz. You would have to test that out yourself though.

[trabang]

SO sick, that fan system could cool a house.

[friends1994to2004]

WTF!?!!? Look at that watercooling system!!! Thats insane dude!!

[Dance2Trance22]

If you want to OC the 2600k to 3.8Ghz..do you still need to get better cooling?

[SingularityComputers]

@Dance2Trance22 No.

[Dance2Trance22]

@SingularityComputers Sweet.

[darkdudironaji]

@Dance2Trance22 HEEEEEEL no. lol

You can overclock it to 4.3~4.5Ghz stable with the stock cooler. You may want to keep an eye on the temp if you do though.

[Dance2Trance22]

@darkdudironaji Alright cool lol I was just looking to get it no higher than 4Ghz anyways..but thanks :)

[AtriX369]

@Dance2Trance22 the 2600K already runs on 3.8 stock when turbo kicks in.

[Dance2Trance22]

@AtriX369 yea I know that now lol

[LewisW97]

Anyone considering getting an i7 2600k for gaming purposes - don't. Just get the i5 2500k it has the same performance in gaming, but if you need video editing you should go with 2600k for hyper threading.

[crazysmogy]

lool what, 3 360 rads for the 2600k?

[SingularityComputers]

@crazysmogy Yep some big overkill. But I didn't build it for this system, just using it temporarily for some overclocking sessions.

[SodiumHydrocxide]

hi i have a gigabyte z68ap-d3 can i overclock my 2600k on this?

[mrvinyc3]

00:29 faaaaar

[blackpheonix200]

Just from what I know mate its just EFI. Not EFI BIOS. The reason for that is (I think) becasue BIOS stands for basic input/output system and....well EFI is not a basic input/output system:P

Thanks

[SingularityComputers]

@blackpheonix200 EFI stands for Extensible Firmware Interface so yes putting that together with BIOS is saying a similar thing twice. The reason I do that though is so that people know what the hell I am talking about. I mean if you just refer to 'it' as the EFI then people are not going to understand, yet. You will notice that everyone else is saying it and writing it the same way as I am.

[blackpheonix200]

@SingularityComputers Cheers for the Reply :) And Yeah now I get why you do it :)

Subbed :)

[BarackMcBush]

@blackpheonix200 Smuck!

[GamingBoozer]

I'm using an ASUS z68 deluxe with an i7-2600k and Corsair-h80 watercooling. And it seems to run ok, though your right it does raise your temps

[rozzalenda123]

just incase if ur wondering about my pc specs:

Asus Sabertooth p67 GTX 580 super clocked 2 way SLI intel i7 2600k OCed @ 4.5ghz + cpu cooler H60 8gb ram 1600mhz HHD 1TB 7200rpm psu 1200w Haf x case 

[rozzalenda123]

I oced my 2600k to 4.5ghz + H60 cooler..before the torture test it was around 30c now after OCing it to 4.5ghz and test..it went to 78c..I closed prime95 and shut down my pc for 30 minutes..now the idle temp stays at 76c ?? am i doing anything wrong?

btw I did everything u did on this vid except the turbo ratio is @45

[PhoenixJuice]

will this work on asrock p67 extreme4?

[SingularityComputers]

@PhoenixJuice The BIOS will of course be different, but yes it should work. Remember its extremely important to stability test and get that voltage down as low as you can.

[tjpld]

Is it a problem when you set VCore to manuall and it uses this voltage for 1.6 Ghz too? Normaly it would reduce the Vcore to around .8 in that case.

[venomx723272]

Hello SingularityComputers. Can you help a newb? I'm getting this same board. What I want to know is... If I mess up and cant start my oc how do I reset the bios/ueif to default? Thank you

[SingularityComputers]

@venomx723272 Yep there is a load defaults option in the save and exit area. If all else fails you can always use the clear CMOS jumper, or remove the CMOS Battery, which clears the BIOS settings and loads defaults.

[venomx723272]

@SingularityComputers Oh Ok. thanks, man.

[nitro300]

That's is a nice bench setup

[SliPaladin]

This would also work with a Sabertooth P67 right?

[Radical011Y]

@SliPaladin The BIOS interface may be slightly different but the same settings should be able to be found and changed

[rozzalenda123]

@SliPaladin yeah it does

[aonutube]

Ok, this is way too much for me.

[drx975]

Why would you err on the high side when picking your first overvolted Vcore?... also is it really common to need 1.35v for 4.4 Ghz? I thought most people could get up pretty high without changing vcore.

[SingularityComputers]

@drx975 You always adjust the voltage on the high side, so that you can at least boot. Then once you are in Windows you can start stability testing and adjusting the voltage downwards, until you find the optimal voltage. You do this by adjusting the voltage downwards until you blue screen, then take it up approx 4 increments. You need a real time OC tool for this and Linx or Prime95. Most people may be able to do 4.4GHz at 1.25v or so, but I have to consider ALL people.

[silvex300]

Tubo is on for my computer but it doesn't clock down from my over clock why ?

[SingularityComputers]

@silvex300 It might just be your power profile in Windows. Make sure you set it to Balanced, assuming you are running Windows 7.

[garysgreat]

@silvex300 Also make sure to set the c states in p67 bios to enabled, so they can propperly communicate to windows power management. Then speedstep etc will kick in!

[SingularityComputers]

@acapon WHAT IS YOUR ROOM TEMPERATURE??? MINE IS 33 DEGREES CELSIUS. THINK ABOUT IT.

[TechNewsWeeklyMMXI]

thanks, that was a good tutorial. also can you tell me how you managed to get AIDA64 EXTREME into the windows 7 gadgets (sidebar)?

[SingularityComputers]

@TechNewsWeeklyMMXI AIDA64 Extreme has a gadget of its own. When you enable 'Vista Sidebar' in the settings, the gadget will appear in the gadget gallery. You then only have to go select the gadget and enable it like any other. To select what you want in the gadget there is another section called 'Sidebar Items'.

[TechNewsWeeklyMMXI]

thanks, that was a good tutorial

[MrKillaManilla]

what would any1 say is a good voltage for a 2600k if you want it to last 3 years providing it stays under 75 deg

[MrSnowmobiling]

I cant get real temp to download...

[landreux1]

Hey I am trying to test if what I changed in the bios in order to overclock has been successful but when I stress test it with Linx then look at aida64 extreme edition (trial version) I see that my CPU cores are working at 100% during the test, temps rise but when I check the overclock section it says I am at 3.4-3.5 mhz with 3% overclock. I adjusted the setting in the Bios to 4.4 however. I don't understand why that number isn't rising or if im looking in the wrong place could you help me out?

[SingularityComputers]

@landreux1 In Windows when you are stress testing, you need to use multiple apps to check your clocks, because some apps don't report correctly. Try having a look at CPU-Z, AI Suite II, the latest version 1.8 of AIDA64. At least one of those should give you the correct settings that you set in the BIOS. If not then you must be doing something wrong in the BIOS and if that's the case comment here again and we can go from there.

[landreux1]

@SingularityComputers Alright I got CPU-Z and that the overclocking is now working. My temp gets to 78c while under Linx stress test using 3072 memory (I don't know how much I should be putting it at). I don't know how to tell if this is stable or unstable and what Temp should i stay clear of. (intel i7 2600k chip, ASUS p8p67 EVO, 8g RAM. EVGA GTX 570HD 1000w power supply, ZALMAN CNPS9900MAX-B 135mm heatsink) I really appreciate your help and if you could help me a little more would be AWESOME!

[PenetrationMode]

whats a safe overclock for a i5 2500k 3.4 ghz, using a power cooler master tx3

[TechNewsWeeklyMMXI]

Hi I would like to get a general idea of the voltages that would be ideal to OC the intel core i5 2500k. And I also have the Asus p8p67 le and nh-d14

Thanks!!

[SingularityComputers]

@TechNewsWeeklyMMXI The voltage you need depends on the clock you would like to set. You start by pushing up your clocks and then you give it more voltage as you need to, to keep it stable. Start high with your voltages and stability test to work your way back and find the lowest possible voltage. You really need to do some more research and watch this guide again. Overclocking takes time to learn, its not easy.

[johnboy73525]

Ok so I'm having some trouble over clocking my i5-2500k, I was at 4.4ghz with 1.305vcore I crashed running 50 loops on maximum settings in intel burn test after 10 runs in. So now I set it at 4.3ghz at 1.290vcore, are my volts fine? Not sure if I need to up the volts or down them? My temps at full load is 69c help me plz!!!

[chap1400]

Awesome dude, thanks for the guide! Btw if i wanted to kick it up a notch to maybe 4.5 or even 4.6, would i need to change the voltages etc again? also im on 4.4 atm, and under full load i get upto about 67degrees, would u describe that as stable for a 24/7 clock?

[SingularityComputers]

@chap1400 You will no doubt need more voltage for a higher overclock, unless you have the voltage adjusted too high already. You will just have to test it to see if you need that voltage. You try to boot at those settings, you run a stability testing app. If you crash then up the voltage 4 increments or so, then test again. You current settings sounds good, 67C is great, you can go all the way up to 85C at 100% load and still be safe for 24/7.

[chap1400]

@SingularityComputers Ok awesome, thanks for the response dude!

[AppleSlize]

What overclock speed do u think will i be able to get stable with 2600k, Noctua d14, p8p67 pro B3, 1600mhz vengeance 8gb?

[SingularityComputers]

@AppleSlize Potentially you will be able to get a minimum of 4.6Ghz, I would say you will be getting close to 5Ghz. It just depends on how good you chip is and also your knowledge of overclocking. But the hardware config is very good.

[skyscraper83]

What a comfortable and safe temperature? You said 85 degrees in your video but that seem to be running too warm for me for a 24/7 oc. I'm running at 4600mhz with Vcore of 1.340v and with a max load temp of 73degrees.  Is this where i should be for this level of overclocking?

[SingularityComputers]

@skyscraper83 I cant answer your question unless I know what your hardware configuration is and also your room temperature when you found your max load temp. I only talk in deltas because otherwise it means nothing. For example, say my room temp is 35C and my CPU temp is 85C, what happens when my room temp goes down to 20C. It means the CPU should be around 70C. So ambient temp makes a massive difference.

[skyscraper83]

What is better Prime95 or Linx? I also find my temps are nearly 10 degrees hotter in Prime95 then Linx. Why do I see such a temp difference between Prime95 blend test and Linx ?

[SingularityComputers]

@skyscraper83 LinX is for a quick stability tests while you are finding a stable voltage, frequency, etc. Once you have done the initial quick stability tests with Linx, you can move onto Prime and do far longer tests to guarantee stability. Prime causes more heat because it must just be a more complex calculation and so puts more pressure on the hardware. I am not exactly sure though, so if someone has an exact answer please put it here in the comments. Thanks for the comments guys.

[kahunaD125]

what exactly do you mean by "2 increments"? is each increment .01v? If so wouldnt that take forever?

[SingularityComputers]

@kahunaD125 Yeah Im pretty sure the increments are .01v haven had the board for a while though. You adjust it from within Windows. If you have an Asus motherboard you can use TurboV. So you just adjust the voltage as you go, per 5 runs of LinX, so yeah it does take quite a while. The more experienced you become the less time it takes, because you can do a bit of guess work.

[TechNewsWeeklyMMXI]

What's the optimum voltage for 4.2-4.5GHz (noob to overclocking I am!)

[SingularityComputers]

@TechNewsWeeklyMMXI It depends on your CPU and motherboard. For the 2600K I would start at about 1.35-1.4V and work my way down. Always start high and stability test and increment the voltage down within Windows until you crash, then take it back up 4 increments or so, to find you optimum voltage. No one can find the optimum voltage straight off, even the best overclocker on the planet. All chips are different, so we all need to test to find it.

[TechNewsWeeklyMMXI]

@SingularityComputers amazing dude! :P

thanks alot, im gonna buy the i5 2500k cos its waaaaaayyy cheaper than the 2600k and performance-wise, its the same (by overclocking it)

[TechNewsWeeklyMMXI]

@SingularityComputers also how did u get AIDA64 into the windows sidebar???

[SingularityComputers]

@TechNewsWeeklyMMXI Its in the settings under 'Vista Sidebar'. You go to File then Preferences, then probably scroll down, then you will see it.

[TechNewsWeeklyMMXI]

First of all great vid (part 1+2). Secondly, since I am going to build my own PC, can u tell me what could be the max. clock I can get with a Corsair H70 CPU cooler? Thanks alot!!

[SingularityComputers]

@TechNewsWeeklyMMXI I have a review on the H70 vs the Noctua NH-D14 vs custom watercooling. Check it out on my channel. It will answer your question and give you a whole lot more info you will no doubt find useful. Its a recent video on my channel and the title makes it pretty obvious. I would post the link here but I cant.

[Phoerocks]

I copied exactly what you have done but no matter how much i stress it, the speed doesn't go avobe 2.4default ghz :S I also use windows xp, could that be the problem? thanks

[SingularityComputers]

@Phoerocks It could be XP not letting the multiplier change dynamically. This would certainly prevent the type of overclocking that we are doing. You could turn of C1E, Speedstep and Turbo and set a permanent overclock that isnt dynamic. Also try updating the BIOS. Best of all though, just upgrade to Windows 7. Then you will have DX11 and far better security. Remember to stability test and get your voltage down to the optimal point. Just ask me if you want to know more about this.

[Phoerocks]

@SingularityComputers Thanks for the reply :) Can you tell me what C1E is? And what are the risks of disabling it?

[SingularityComputers]

@Phoerocks C1E is basically to reduce heat and power consumption. It allows your multiplier and voltage to reduce right down when the CPU is in a halted state, basically 0% load. If you disable it, it means that your CPU doesnt clock down anymore. I cant go right into all the details because its very lengthy, but when you disable this you need to disable Speedstep and Turbo as well, to stop all dynamic overclocking. All this means is that the CPU stays at the same voltage and clock all the time.

[SingularityComputers]

@Phoerocks So what we are trying to achieve is stop all dynamic overclocking. This might fix your problem, but it is not the best way to fix it. Update your BIOS and get Windows 7. You really should do those things anyway. Then you dont have to worry about doing all these things. There is always risks when overclocking and changing BIOS settings. You need to be very careful and do your research.

[PossiblePoison]

Regarding my previous comment, I really should of watched the video before commenting haha. You covered just what I was asking about.

I think I'm going to go with the turbo mode route instead of the constant OC, to save power. I won't be gaming 24/7 anyway.

[PossiblePoison]

Whats your view on constant overclock and variable (I'm sure they have other names) I mean, having the the CPU locked to your OC settings, vs having it overclock when needed

I'm wondering if I can set all the appropriate voltages etc but have it overclock to about 4.7 when it's actually needed

[IMIDefender]

Why you set Load-Line Calibration to Extreme and CPU voltage to 1.4V ? I have same system and it`s stable on Load-Line calib. - Standart and CPU voltage offset +

No extra voltage to CPU

1.4V for idle CPU speed and 4.4GHz is too much. I set ~1.4V for 4.8GHz on air cooling

[SingularityComputers]

@IMIDefender I did that because this is a tutorial for everybody. All chips are different, some are better than others. I wanted to give settings that are going to work for everybody. Then each person can tweak those settings and get the voltages down and temps down until its perfect. This is just a base line overclock that I hope is going to work on all chips, bad and good. Think about it. Yeah you can get that on your chip, but what about the whole bunch of people with lower binned chips.

[Russian7002]

Hey dude, great tutorial. I have a few questions, 1) why you did not adjust the VRM? You left it on auto. In asus overcklock guide they put it to manual. 2) I have p67 deluxe mobo, does it maintain 1.65v as default ram voltage?

Thanks

[SingularityComputers]

@Russian7002 I didnt adjust the VRM because the overclock was too low to need any VRM adjustments. Watch Part 2 of the guide and you will see that I adjust the VRM's for the 5Ghz overclock that I achieve.

[kahunaD125]

how do you figure out how many volts you need for each clock speed

[SingularityComputers]

@kahunaD125 For a first run you need to either take an educated guess or do some research to see what profiles other people use. This overclocking video gives an example of a profile that others can use. Once you manage to actually boot though, then you start stability testing, like I explain in the video. Stability testing is to find 'how many volts you need for each clock speed'.

[8izzi8]

What happens when you press the "Start Overclock" botton on the Asus Maximus IV Mainboard?

[SingularityComputers]

@8izzi8 I haven't had the privilege of laying my hand on this board yet, so I am not entirely sure. I assume that it starts an auto overclock process that a lot of Asus boards have these days. It basically automates the process of stability testing and finding the best overclock for that particular config.

[madgnad]

I'm not trying to bash your video at all, but I saw someone in another video running a Noctua NH-D14 at 5.1GHz and it was in the 70c's is there something going on with your water cooling ? This is a very helpful video for those of us that want to overclock the SB and since I'm new to i7, I find this helpful.

[SingularityComputers]

@madgnad Have you considered that my ambient temperature may be higher than this other person. Also that the other person wasnt running apps that make their CPU really hot such as Prime 95 or LinX or Intelburntest. I am always explaining to people that my ambient temperature is constantly 35C. Most people who overclock live in cold climates and have an ambient temp that is often 15C colder than mine. That means 15C less temperature on the CPU. Think about it.

[madgnad]

@SingularityComputers So it's 95 degrees Fahrenheit in that room? damn dude. I would have bought an air-conditioner by now, lol.

[SingularityComputers]

@madgnad Yeah I know, its pretty bad lol. The thing is, there is an aircon just outside this room, but because of the heat from my systems it does nothing. Its because my systems are all highly overclocked and water-cooled. So the heat exchange into the air is massive.

[Luger718A1]

now that we overclock without turbo (if you know what i mean) is there any other settings we should change other then load line calibration?

[SingularityComputers]

@Luger718A1 Well we actually overclock Turbo itself now. What settings you need to change, depends how far you are overclocking. To maintain stability as you achieve higher and higher overclocks, you can adjust all the VRM settings upwards. At 4.8Ghz I have my VRM settings maxed out. Other than that, I guess you can disable spread spectrum and you could play with the PLL voltage. Certainly tweak your memory too. Sandybridge overclocking is very simplistic. Theres not much to play with.
