E8400 @ 4.0GHz P5K-E BIOS Settings with Commentary

[kill10003]

how do you open the bios anyway

[RickArter]

@kill10003 You do not open is as much as enter it when your PC starts it will say hit x button to enter set up. Usually it is delete or f1 on most motherboards..

i hv the exactly same mb and cpu as urs, and im wondering if it is possible to make it fsb @500 (which i alrdy did since i hv a set of 1066 ram, running at 1002. and cpu at 3.5Ghz) and 4.0Ghz cpu speed at the same time?

thanks

[6loooool]

GoT WeeD ?

[JollySwagman2006]

Man 1.46v ,, dam thats High , the wife's 8400 CO does4.0 @ 1,27 or 1.35

My 8400EO does it @ 1.27 and my E8500 EO 4.0 @ 1.25v

so you shouldnt need that much for stable clock

[Japao01]

@JollySwagman2006 - well, i needed 1.5 V for the cpu @ 4.5 GHz - no harm at all with the right cooling ;)

[alexe693]

@JollySwagman2006 he said that his vdroop brings it down to like 1.3 or something

[Japao01]

Hey Rick nice vid though, thumbs up...before i got my q9450 i had a e8400 as well and reached 4.5 GHz (rev. C0) stable with watercooling, 8x multiplier, 562 MHz fsb...but that was the point man-just to mention the reserves of this cpu | still have screenshots^^

[djkub1]

I am almost a noob to overclocking. I currently have my e8400 at 3.8Ghz.

I got my voltages set to 1.3 but for some reason when I boot into windows cpuZ reports the voltage at 1.26-1.28 volts. I have a Gigabyte motherboard I disabled EIST and doesen't help.

[alexe693]

@djkub1 this is what is known as vdrop (voltage drop) it happens to all mobo's and its a part of overclocking..you have to compensate for this by raising the voltage so that under load when it "drops" it will still be enough to run it stable

[djkub1]

@alexe693 I discovered what vdroop was a good while back. I rarely have BSODs and I recently ran a memtest and I saw 1 error.

Do you think the problem is because I don't have my ram voltages set right? I am hoping it is my noobish overclock that is causing the problem and not actually the ram.

[alexe693]

@djkub1 usually keep your ram voltage settings to what the package tells you to set it at. I never overclock my ram just because its already pretty fast (ddr3 1600) and if i do i tighten up the timings instead of raising the speed. I would try restoring your ram to its default settings and run a memtest that will most likely tell you if its defective or not

[Rammkopf]

Hey mate! Have you tried overclocking it a bit more? I'd go for a slightly different setup there. CPU multi [8.0], FSB Strap to NB [400], FSB freq [500], PCI-e [100], DRAM [DDR2-1000], your RAM timings are OK, DRAM SRC [Enabled], Transaction Booser [Enabled], Boost Level [0], CPU VCC [1.46]~[1.47] for C0 stepping and [1.35]~[1.40] for E0, CPU PLL [1.50], FSB Termination [1.40], DRAM Vcc [2.10], NB Vcc [1.55], SB Vcc is OK, Clock Overcrg [1.0], LLC is OK, both GTL Ref Voltages below at [x0.61]

[Rammkopf]

Spread spectrums should be [Disabled], so you got them right, also the CPU and NB clock skews should be set to [Normal]. At least this is my setup on a P5K Premium with a E6300 (the latest Wolfdale-2M) running @ 4GHz sharp. I also had an E8400 C0 running on a Rampage Formula with similar settings. In fact, first I got to overclock the E8400 to 4.125GHz on the Rampage, then put in about the same values in the P5K BIOS (this one having significantly less options though) for the E6300 and there! :)

[Rammkopf]

Can you try that and let me know how it works out for ya? I'd be more than glad to learn that it runs like charm. Should run seemingly faster than this current setup too, especially when it comes down to RAM operation. Oh, if your E8400 is of the E0 stepping, you could go a little loose on that multiplier. =) I nailed mine down to 8.0 because of my cores being a crappy rev C0 and it took them 1.45V for real to get to 4.125GHz. You should need way less juice for an E0.

[j7x54]

thanks for the info

[vipergtsr20]

same here 1.32v at 4ghz (^_^)

[baziquee]

my e8400 could do with 1.25v but i use 1.35v because im a pro skillah

[orrekorre]

lol 1.46 volt for that cpu is much. my  e8500 in 4 ghz runs at 1.35v

[sk8er840]

But i have Vista and when i start my computer it just says F1 Setup And F2 Boot Menu And i dont see Underclocking in bnoth in them :o

[sk8er840]

How Do You GO IN BIos First Of All ..

[RickArter]

Delete or F1 or maybe F2 mostly delete on newer non OEM boards and even some of those too.

[xXgodOFsnipexX]

what fans do you have?

[xXgodOFsnipexX]

whats your motherboard?

[wallenholm]

you press Delete when you starting you Pc:D

[sk8er840]

How Do We Go In Bios In The Beginining ?

[Diegog5]

Hi RickArter

I just started overclocking my cpu a couple of days ago I also have an e8400 at 4.ghz. Everything is stable but what concerns me is that I have a 550 watts power supply which seems kind of low. Just want to ask you how many watts is your power supply?

Thanks

[illmaticways]

what chipset is the p5k-e?

[RickArter]

Intel P35

[XFilms95]

why is your PCIE frequency at 101?

[RickArter]

Google it long story.

[trixorz1337]

How to u get into " Bios setup " ? got big problems whit my new computer and need to get into BIOS setups.. Help!

[illmaticways]

What are your temps at full load at 4ghz and also whats your cooling solution? (air/water)

[RickArter]

Check my other vids got a lapped true120 temps are bout mid 60s loaded in a warm room.

[illmaticways]

too many vids, link me to the specific one. :D

[MAGRAO54]

Hello friend, what use ((virtualizaton technology support)) in the processor does not have this difference? else it supports well in my motherboard Asus P5GC-MX/1333?

[RickArter]

that is for running virtual machines on your rig if you dont run them you can disable it.

[stephane082009]

super great job

[beastson]

what kind of ram were you running at the time?

[RickArter]

Crucial Ballistix double sided DIMMs 800mhz 2.2v 4-4-4-12 at 1100-1250mhz 5-5-5-18 2.25v suicide run/bench stable.

[simracr94]

holy crap! i thought .05 volts for vdrop was bad!

[nametoberealized]

i can't seem to pass 2.56 with an e2140 on a p5ke 1202 bios

scythe ninja heatsink - 2gb ddr2800 corsair xms2 with alu heatspreader...

tried strap at auto/266 fsb at 300... multi at 6...

any advice for me?

[gugkjkj]

that's one noisy pc

[youngchung2]

i did quick changes (no voltage changes) to get it to 3.6ghz and the idle vcore is 1.312...is that right?

[RickArter]

Seems a bit high I run 3.6ghz on this chip with 1.192v under load and 1.200v idle. Too much volts can be bad as well and set your vcore manually it must be on auto now.

[tourofheads]

I would try lowering it a bit.... Currently I'm fairly stable at 3.8ghz and 1.235v.

[Homebrew2all]

what heatsink are you using for 4.0ghz?

[RickArter]

TRUE120 Black lapped with dual fan but running passive now at stock clocks with 50c load temps

[HomlessEddie]

What are your idle temps.? I have this at the stock settings with the Zalman 9700 cooler plus Arctic Sliver 5 and my idle temps. are about 40 celsius.

[RickArter]

Mine are about 40-41c at 1.368v and 4ghz speeds. Stock is about same at 39c. Load is where things count my load at stock is like 44-45c and at 4ghz its like 52-56c depends on ambient.

[HomlessEddie]

So those temps i posted are nothing to worry about?

[SilentDude56k]

Very nice, I might just try out your overclock. I've had problems with video performance when overclocking with this board. Increasing the Northbridge voltage to 1.40v was necessary to bring the PCIe bus back up to 16x, but game framerates were about cut in half regardless. I've tried 3.2, 3.4, 3.6, 3.8, and 4.0 GHz with the same problem. I've heard there are FSB "holes" with this board, which can possibly cause this problem if the FSB is set within these ranges. Anyway, thanks for sharing!

[SilentDude56k]

Got around to updating my BIOS from 0906 to the latest 1202, and that solved my problem. It seemed stable enough, but temps of 60c under load kept me from running Prime95 for very long. I'll get a good Zalman cooler before I try again I think.

[spencerpoyle2004]

due to variable vdroop between different motherboards and other factors you shouldnt apply these settings directly. instead do it the right way and gradually increase your overclock, atleast then you will get a basic idea of how to overclock yourself.

[adrian1218]

i can OC e8400 3.0ghz @4.0ghz On air Cooling using cooler ZALMAN CNPS9700 LED 110mm 2 Ball CPU Cooler and my mobo is ASUS P5Q Pro LGA 775 Intel P45 ATX Intel Motherboard

can get 4.0ghz? stable or more

[lldhmra]

Good work Rick.

I think you give a little more GHZ, but give more GHZ on a P35 motherboard with air cooling hmmm... I think it is difficult, but you're in a good way;)

Cumps.

[liamisic911]

get a bios update

[computers1993]

i got the E8400 and the P5N-E SLI motherboard and when it boots up it says: unknown CPU detected BIOS updated need to unleash the full potentional and then down the bottem it says: F1 to continue or F9(i think) to enter BIOS. but other than that everythings else is fine, how do i fix my problem??

thanks computers1993

[RickArter]

Update BIOS got to be losing performance.

[computers1993]

how exactly do you do that??

thanks computers1993

[GTCandyMAn]

LOL 4ghz :O

[LinkinX64]

love the Commentary btw

[RickArter]

Thanks for watching you guys are great audience.

[LinkinX64]

I cant wait till I get my new fans so I can copy you lol

[coolermaster644]

Your cool rick awesome job

[MN12BIRD]

Wow you have really learned a lot recently eh? Tons of tweaking options on that board compared to what I'm used to anyway! I never knew you could change the voltage on the NB and SB for example!

[jrodwwe94]

awesome man

[Artificialkel]

Cool, Well what I understood, I'm trying :D
