E8400 @ 4005MHz 1.352v 19 Hours STABLE!!!

[cookiedoh1234914]

what Cpu cooler are you using? because i got my e8400 @ 3.6ghz on stock cooler and i want to OC it even more

[SerzantasLTU]

i run 4.2 ghz on lower voltage.

[TheGamesHD]

could u actually help me with my E8400 and P5Q-E?

[djkub1]

I am a noob at overclocking basicly but I have my e8400 at 3.8Ghz. My voltages are set manually in my bios to 1.3 volts but cpuz reports it at 1.26-1.28 volts for some reason. Maybe something is blocking it.

anyhow my idle temps at that clock range from 38-40C.

I have a gigabyte motherboard

[RickArter]

@djkub1 The real vcore is read in windows under full load. It is a thing called vdroop it is diff between BIOS and load volts.

[djkub1]

@RickArter Thank you for clearing that up for me, although I have did a bit of research about vdroop.

[PaRan0iiid]

I have my E8400@4,4Ghz 1,4V on Asus Striker II Extreme

[matrixITALIA]

Do u keep the cpu at 4.00gz daily!? CANNOT IT BE DANGEROUS^?

[UchihaDark38]

im running 4.18 ghz for over a year now and never had any problems even when the cpu is at 1.52v

[simracr94]

if you keep the voltages within limits you can run chips at unbelievable speeds and not have any problems whatsoever

[matrixITALIA]

thks m8! i will try! ;)

[SirOMFGlich]

My E8400 E0 runs @4.0ghz 24/7 @ 1.3v it's 65°c warm max. sry for my bad english

[DeltaForceSFODD]

Ok so i have decided to get a E8400 and overclock it to those speeds but is there a certain version i would need to look out for? Also you got it on air alone correct?

[RickArter]

Get the E0 stepping most new ones are this stepping and yes this was with air cooling.

The E0 stepping you can get almost 4.2ghz in some cases depends on chip.

[narcis4none]

Tank you

[narcis4none]

I'm using my stock fan on intel pentium e5200,i overclocket at 3Ghz idle 43 degress,load 55 is it save? sory for the bad english....

[RickArter]

Yes that cpu can go up to 73.2c I believe under load just keep vcore under 1.36v 24/7

[Dj2Fox]

^^ i just made my E8400 4.5ghz stable at 1.392v ^^ memory 1333mhz 7-7-7-20 1.6v

I got a Asus Rampage Extreme ^ :P

[garymofo2]

god dam im running 4ghz at 1.298volts in orthos and im getting 70-80c degrees! Its stable but I stopped it after an hour because I dont want my cpu to fry. Right now, I have it OC'd to 4.18 at 1.368 volts. Not stable at 100% load but Stable enough to run the game crysis for periods of time

[RickArter]

You wont fry your cpu loading it unless its super hot and run over 1.4v or so vcore 24/7

[biganz]

Good efort. Due to limitations of RAm against memory divider on my mobo I am using E8400 @ 3.6GHz but it is 450 * 8 on 1:1 @ 4-4-4-12.

No disrespect Bongman but you have no idea what you are talking about.

[pyckMeister]

you should be running 2 of those to fully stress cpu to 100 % THEN you wil know for shure if its stable

[RickArter]

Single instance is plenty for my preferences. I run linpack then few hours of orthos now and its perfectly stable.

[flipboi87]

trippy.. the day i built my system =O

[RickArter]

4.2GHz benches coming later this week.

[bongman4ghz]

fsb wall for this pile of shit is 540mhz.

thats if you even get there.

[bongman4ghz]

445mhz x9 thats a fucking joke.

this cpu is maxed you fucking idiot.

[remi1913]

please try  OCCT 2.0.0a...

[RickArter]

Use it some not as big of a hit as orthos or prime95.

[bongman4ghz]

your idle temp is higher than my full load temp.

lmao. look at video response.

[RickArter]

My vcore is bunch higher whats your room temp?

Your vcore is like 1.25 mine is like 1.365.

44c IDLE

64c LOAD

smallFFTs in Orthos. I can live with it got a crappy mounting job this time I guess.

[bongman4ghz]

my room temp is just around 20C i think.

just buy a proper cooler.

like a heatsink directly conneted to the fan.

you got heatpipes that dont work going to the heatsink then being cooled.

ill send pm recommending a cooler.

[LinkinX64]

Post the Bios settings!!

[RickArter]

In the video response is the BIOS settings.

[dunlrock]

get TRUE :D

[RickArter]

BIOS settings are key and I got a TT Big Typhoon lapped with a 107cfm fan.

[OpaqueNoise]

I'm thinking about picking up a E8500 and hoping to get results as good as this.

What will you be doing with this CPU? Gaming?

[RickArter]

Gaming no not really not yet anyways I just benchmark and use the internet a bunch. Starting to get into gaming but need a better video card.

[Kaspar008]

good job man

[soma1509]

Good work man. I just started getting into overclocking, but I suck right now. I tried a mild overclock on my E6850 with my new 750i MSI mobo, and it doesn't go any higher than 3000.5 MHz without upping the voltage. So far it's running cool at 26C, but I don't want to go crazy, I just want it to go to 3.2GHz and leave that as the sweet spot. I tried upping the FSB on the BIOS and it did POST afterwards, but on CPU-Z its telling me otherwise. Any tips would be appreciated.

Btw, new video soon

[bongman4ghz]

your another bullshiter.

3ghz cpu 26C idle.

fuck off.

[GamersVilleNet]

amen

[SynCroNiz3]

It seems ur vcore is pretty high, but im assuming u might need it that high to keep it stable, unless you haven't tried bringing it down much. As of right now I have my e8400 @ 4ghz with 1.296, but i haven't tried stressing it for very long, i should get on it though.

[RickArter]

It would fail at any lower but one I work around some of the other voltages and GTL ratios might be able to lower it.

[SynCroNiz3]

ahh i c, well good luck on it, and I'm pretty sure you'll be able to take this processor to at least 4.5. I actually haven't tried to find a maximum overclock for mine, but i think i might try and post a video for comparison = ).

[SimonLANO]

Nice, is a E8400 Oc to 4.0 Ghz better than a Q6660 Oc to 3.51 GHz?

[RickArter]

I think with things that cant use 4 core maybe but not really if you think overall.

[ifuxwituz]

i have both chips and the Q6600 looks faster @ 3.2 then the E8400 i have @ 4.0

[bongman4ghz]

silly question.

[keldererik]

My E8400 runs on 4005MHz 1.3V (bios) 1.264V (windows) 8 Hours orthos stable. :P hehehe

[overclockerfx]

Rick i think that 6 hours is about sufficient... thats a little overkill even 12 hours is on the edge...

[RickArter]

8-12 hours is good enough and for as high an oc as I got 21 hours was what I wanted to do.

I will only deem higher overclocks stable if they pass 24 hours of Orthos or Prime95 from now on worth it I think haven't had a hiccup yet at 4ghz.

[finland413]

i guess its more of a matter of taste... i usually run max 6 hours orthos and then play some cpu and gpu intensive games and run some benchmarks and then deem the system stable...

[Fightbird2013]

Thats insane man!!

---> pleas tell me who is the name of your loop

[svtcontour]

Wow thats good man. Impressive. Thats what dedication gets you :)

[altosinclair]

Can we see a vid of your bios screen and show us what you did to get to 4.0Ghz. I cant get mine passed 3.8, I wanna see what I am doing differently.

[RickArter]

Give me a minute I will

[MN12BIRD]

Distance to TJ MAX? LOL!

[ThatFlipKidxD]

*Crashes*

[RickArter]

I thought that the whole time let it go 9 hours at the end when I went to work good thing I did.

[bongman4ghz]

stressing a processor for that long is completely pointless.

will you ever do a task that puts the cpu under 100% load for 19 hours?

[joepic85]

I tell him the same thing  ;)

[bongman4ghz]

he needs mental help dude. ;)

[RickArter]

You both are overclocking noobs don't tell me what to do with my 175 dollar CPU.

This is too joe and bongfag2.5ghz

[bongman4ghz]

you dont even know how to overclock you fucking idiot out the multi up you reject.

[badh8me]

great 5/5!! keep em comming! 4.2 Ghz!!!

[bob333336]

oh its shits and giggles :P get a true120 u will get lower themps at 4.2ghz with it

[RickArter]

I might with a push pull SCYTHE super-kaze set up SWEET! mother of air cooling.

[bob333336]

nice i think u can push it to 4.2

[LoCoBoi187]

Hey Rick can u explain to me what "FSB STRAP TO NORTH BRIDGE" is? The options it gives me is in mHz, and is higher better? or lower? TY

[RickArter]

Really depends what RAM speed you are running and it has to do with latencys of the NB in technical terms.

Higher the overclock and the slower the RAM you are running usually you will go to a higher strap. Like I can only run on the 333/400 strap because of my 800mhz RAM. That was a crappy explanation but I am sure someone else will show me up on this question.

It determines what your RAM speed will be in relation to your FSB and the divider that will be run between the two.

[MN12BIRD]

Cool. You can also unlock the NB from the FSB can you not?? Keep your RAM at stock speeds and only OC the CPU FSB? That would help determine MAXIMUM OC for the first trials as it would take your RAM out of the equation. Nice to see 4GHZ on these. I sell them and am always telling people ~4 on air cooling is possible. Nice to see it in action this time.

[RickArter]

Kinda but depends your FSB really. Like a 800MHz FSB CPU can run 200/266/333 straps where a 1333FSB can only run 333/400 straps. I guess you could run 266 but why like I said 1:1 is optimal and most mobos can run linked or unlinked going along with what you said to a point.

[Maidock]

Nice. I got 4.8 GHZ by accident on air on an E7200 (65nm E8400, basically.) and it was pretty much stable. I didn't realize the insane overclock I accidentally set and I was playing some Unreal Tournament 3 and Crysis without hiccups. I eventually blue screened most likely due to improper voltage. That CPU is fine today at 3.4 GHZ, and I most likely damaged it, so I'm not trying it ever again lol.

[Neosferaku]

Wrong, its 45nm. half the cache. whats your cooling setup?

[RickArter]

TT Big Typhoon lapped with AS5 and Silverstone FM-122 107cfm fan.

[RickArter]

If vcore and other voltages were in spec no damage should have been done. Nice job it was stable that long.

[Maidock]

I really have no idea, because I checked almost nothing during the o/c as it was all by mistake (I meant to quit BIOS without saving, but apparently I did.) when I found out the CPU was clocked so high I freaked out and unplugged the whole thing lol.

[buzzin92]

wow, Great overclock mate, 4Ghz achieved on air kwl, even though there using liquid nitrogen to get at that speed but still lol, congratulations

[RickArter]

It was not as hard as I thought with having such a high FSB on the P5K-E. The chipset is all at lowest voltages except NB which is at 1.40v gonna try lowering that as well. Not sure if vcore can go lower will try below 1.350v would be nice. Going to pump it up to 1.4v and try for 4.2ghz soon.

[buzzin92]

nice, hope that works, especially on air cooling lol. i have an old intel celeron 430 in my back-up system and iv got that runnin at 3.7Ghz from 1.8, iv set all the default voltages exept for the cpu, i lowered it from 1.25 to 1.15 and its run stable for 48 hours and its on stock cooler so i dont think you should have any trouble with the 4.2 as long as it doesnt overheat at those voltages. good luck with it

[KandAshow]

I got my Q94 at 3.5 stable. Great job getting 4GHz.

[RickArter]

Good overclock whats the FSB?

Finally shut it off at 21 hours and 51 minutes.

Good enough going to go through some settings and try for 4.1 stable but voltage is at the limit for 24/7 after one more notch up.

Temps are a bit high but got a bad mount got a solution for that just wait and see.

[KandAshow]

Bus speed is 438 multiplier is 8

FSB is 1752.2

Mems at 1050

Whats your FSB and MEM at?

[LoCoBoi187]

l00k @ video tags :p

[RickArter]

445x9- 4005MHz

FSB- 1780mhz

RAM- 880MHz 2.2v 5-5-5-15 2T.

[jrodwwe94]

Wow, your trying for 4.3 on air

Nice stuff man, all of your stuff is great

I love that CPU

5*

[RickArter]

Thanks you guess comment so much I love it have a great day.

[jrodwwe94]

Haha, thank you

And you'v made me want to get one if these in my new build
