**Official e8400/e8500 Retail OC Thread

your E8500 at 4.34GHZ with 1.304 is stable? which mobo?
my temps on 1.336V 4.05GHZ are at load 52 max and with IBT its 66 max at load.

any chance to get 4.5GHZ on air with P5Q Pro on safety Vcore&NB?

Running these stress tests (that stress the CPU far more than anything else) repeatedly, especially IBT and sometimes prime small fft on hours/days on end, is not really healthy for these chips when they're pushed too hard. Your chip might be degrading from it. Seen it happen plenty enough. One guy degraded from 3.6 to 3.4 ghz (needed higher vcore--1.34 vs 1.32v) for 3.6 after a few weeks of repeated IBT's. And 1.32v isn't even that high.

Yes it's possible for chips to degrade even at lower voltages.
All chips respond differently, so what may happen to 1 person might not happen to someone else. Board timings/settings may play a part too.

There have been cases where it was the northbridge going south, or RAM, but memtest would pick that up (you'd probably need something a bit tougher on the NB to pick up problems there, like Orthos/prime Blend).

---

Thats exactly what i did though...

Ran IBT for a solid 45mins/1hr and temps were a champ, stable as.
Also did memtest initially etc etc.
And a prime blend overnight etc.

I didn't run a stress test after that. It was only on the stupid hot day here it crashed, and since then not quite the same
And i game on it daily without issue

Im still yet to see if its the ram or the chip, no time to test yet though.
It was fine for what 2 months maybe 3 without problemos and my temps are very low too.
Will do digging tonight perhaps

Yes completely stable on the P5Q Deluxe, at the settings I mentioned earlier. I would like a higher FSB though. Need to start testing again soon. I would like something in the 550fsb area with a clock of 4950 @ 1.45 or so, we'll see how she goes.

ok so tested the ram over the last 3-4hrs... seems thats not it!
Held the ground fine.

So this time back to near the old settings, slightly lower FSB (470 for now) and will see how it goes
Could just be i need another notch of vcore perhaps for 4.3, so sitting on 1.296 vcore with a lower clock for now

Stupid E8400 again, even E0. Just bought it yesterday and one of the temp sensors is stuck at 39, it goes up a little if I torture it, but otherwise, it's always at 39. Dam...I am beginning to hate E8400! Why do I even want it anyway...?

because he is good clocker? :rolleyes:

my sensors are stuck too, if you pass the 50C~ the sensors going to be normal.

No, they never go past 47 even many hours of intense torturing. When tortures, the other non-stuck sensor rises to 39 and then both would go up together. When they cool down, the stuck sensor comes back to stay at 39 while the other one goes down all the way to 32. I haven't tried OCing the CPU yet. I should to see how well (or bad) it OCs. We shall see.

Must be the latest batch of chips because mine also are stuck at 39 at idle. They do go up to 57 load.

I've had my E8400 rig for over 6 months and just now getting around to trying an OC.

What's a 24/7 maximum safe temp under stress test?

Right now I'm stress testing my E8400/C0 1.33V BIOS 1.28V CPU-Z w/P5Q-E at 400 FSB 3.6Ghz CPU memory G.Skill 2x2GB at 1:1 400 Mhz and I've hit 62 degC on Core0 and 59 degC on Core1 after only 10 min of P95 blend.

Should I try for 3.8 Ghz?

I'm going to try your BIOS settings below. Thanks for posting them. And nice OC. :up:

Edit 1:

Well I booted with your settings but with FSB at 425 without a hitch. Starting stress testing...
Edit 2:

No go at 425, I had an error then a lock-up. Trying 415. Temps got to 67/65. I don't think my fans are running at 2k RPM under load. I'm going to investigate this in the BIOS.

Edit 3:

LOL! I just open my case and realized I was running the stock Heatsink and Fan. I had trouble fitting the TT "super" Sonic Tower on the CPU so I just slapped the Intel unit on.

I think a cooling upgrade is in order before I go beyond 3.5 Ghz.

Edit 4:

Max temp with the Super Sonic Tower 1.328V CPU-Z 400 FSB is 40/39 degC. That's more like it.

Edit 5:

Two hours into 3.8Ghz, no errors...

Okay, I'm 2hr of P95 and IBT stable with these settings, from PakaPake, Thanks. I can boot Windows at 4Ghz but after only a few seconds P95 fails. IBT loaded both cores to 60 C, surprisingly much higher temps then P95, but my temps seem to be good.

Yeah mine sits around 36-43 @ idle (22 degree room) and that's sitting @ 4.3ghz and a vcore thats a bit higher... Load is 48-50 degree
All things considered compared to those results mine are pretty decent temps

vFSB above 1.14 will NOT necessarily damage a cpu unless you take it too far. 1.20 is perfectly safe and some older boards won't even go below 1.20, so that's stock for those boards. 1.30vfsb is when you start to get into overclocking territory. Zero danger in using 1.20 vfsb.

I do agree that you shouldn't need high vfsb settings unless you're trying to go above 400 mhz.

ooo correction - 48-50 under load - sorry i meant @ idle (ive edited to reflect correctness! hehe)
And its 36-43... 2hrs sleep isnt my friend :D

Either is fine. 1.24v will not harm you in the least.
I would personally not go above 1.30v, though.

Being scared of 1.20 vfsb is like being scared of putting 1.30v into a 1.25v cpu...

I have a similar chip. It lives on @ 1.2V 4Ghz. Needs about 1.35V for 4.4Ghz. Not worth the extra heat output IMO.

i wasn't talking about 4 GHz. i was talking about running Orthos @ 20 watts.

CandymanCan / PakaPaka,

I think you're right about having a poor E8400/CO. I couldn't get stable anywhere near 4 Ghz. I've settled on 3.6 Ghz @ 1.272 Vcore for a 24/7 running, which is more then enough HP to run a web browser...

The highest setting in the BIOS for tRAS is 31. The only setting that goes to 65 is tRFC. I think my memory is unstable much above 400 Mhz.

my E0 runs better at low voltage than my C0 did, but it doesn't seem any better at or above 4.0 GHz. in fact, i think my C0 was a better clocker. i'll put up more when i do the work. for now, 425x9 @ 1.200 vCore load is stable.

http://i21.photobucket.com/albums/b2...1-200vcore.jpg

had my cpu running 1.408V 512x9 for several months now 24/7....just bought a q9450 and will most likely be selling this chip so I decided to do some lower voltage prime runs to help it sell, and I'm pleasantly surprised!

http://img105.imageshack.us/img105/7318/4500test.png

i just picked up a e8400 i guess its an es. my last wolfdale was a e3110 that i had @ 4.1. so hopefully i can now get higher than 3.6. crappy e6600.

its a Q739A

Its still a touchy subject but intel clearly states not to go over 1.14v unless you want to risk ruining your cpu.

I dont even need to go above 1.10vfsb to get 4200mhz or 4300mhz.

Fankr you have the same ram i do just rebranded "8000" change your tras cycle time to 65, the Auto setting doesnt work well for this memory. Change the FSB strap to 333mhz, you dont need 2.10v for your memory at such low overclocks. Keep all those settings you have on disabled on Auto except Cpu spread sprectrum. I found turning them on disable like that hamperd my overclocks. You also most certantly do not need 1.26VFSB for 3.8ghz. Stop listening to these people.

You most likely have a bad batch CO, check the first page you will notice most older e8400's dont go beyond 4ghz if at all even using 1.37vcore.

What do you mean 1.14v will not dmg unless you take it to far?

See iv gone to 1.20v to test and stuff, like for me my maximum overclock is 4400mhz 489x9, with 1.36-1.37vcore and 1.22vfsb. The problem with that is i can also do 4200mhz 1.28vcore 1.10vfsb. Which is what iv been using 247. Which would you use 24/7 ? See what iv been thinking of doing is 500x8.5 4250mhz that way i dont need the high vcore but the issue is i still need the high vfsb. This the rare batch CO stepping, so im lucky i can even reach 4400mhz on a CO lol

I play Warhammer online and all i do is pvp and the game is really cpu intense, on large pvp battles i have to turn the graphics down so iv been thinking maybe i should overclock to my maximum but im afraid to use those voltages 24/7. Since the game doesnt have a benchmark im not sure if 33fsb and 200mhz will even give me a fps increase

Think about it of course most e8400's can run stock at like 1.10vcore but my point being is the vid is usually 1.20 or 1.25v so use that towards your point you made and increase the voltage by the 0.15v like on the VTT and all of a sudden it becomes pretty high.

---

I have not seen an intel data sheet ever state not to go over 1.14v Vtt. If you look at the intel e8000 series data sheet, it clearly states for 3 series (P35 etc) chipsets a Vtt of 1.10v should be used with a max of 1.155v. However on 4 series (P45/X48) intel states Vtt of 1.20v should be used, with a max of 1.26v. Staying within those voltage ranges is completely safe, I'm not sure why you thought any differently.

I've been using 1.37v VTT 7/24 and didn't found any issues...

currently 7.5x600 4.5Ghz @1.375v BIOS, E8500...;)

whe3ls,
thanks for the quick response but that is no joy

i dont know what is up with this board?

cpu is running @ -40c and i cant even get 3.8ghz to be stable?!?! this is my 2nd cpu frist was a cheap e5400 that wouldnt break 3.6ghz and now this E8500...what gives

Now hitting 4.2GHZ still same Vcore , dare i say a great Chip :D

not bad. thats a nice chip.

Lowering Vcore a bit now @ 1.22V after the Vdrop , my C0 went as low as 1.36V :D , too bad that the P31-DS3l holds me

dang. you need better cooling a better board. lol by the looks for it you could go higher than 4.5


and i think my dfi 680i is holding me back.

Cpuz does not read the .5 multi :up: As you can see it only reads 9x multi.

this version does http://img13.imageshack.us/img13/1497/cpuzjpg.png

Ye my CPU-Z reads .5

Thanks for earlier clarification - why i didnt think of that i dunno :)

Hmm, not really sure why it doesn't read it :confused: It is the latest version of Cpuz 1.5.

C-BuZz

Using an e8400 here, why is it that in cpuz the core clock jumps from 1998.0mhz to 2997.0mhz while the multiplier jumps from 6x to 9x @ 333mhz fsb. Is it suposed to be doing this?

thanks.

Thats because you have the power saving thingys on. Therefore when the CPU is idle it reduces the multi to 6 to save power and when its under load it increases it to 9.

They are called

CPU Enhanced Halt (C1E)
C2/C2E State Support
x C4/C4E State Support
CPU EIST Function

(Thats what they are in my BIOS, I don't know about yours)

MaByBoI,here you guy diable these in bios.edit-fatguy got there first
Limit CPUID Max to 3............................[ Disabled ]
No-Execute memory Protect.......................[ Disabled ]
CPU Enhance Halt (CIE)..........................[ Disabled ]
C2/C2E State Support............................[ Disabled ]
C4/C4E State Support............................[ Disabled ]
CPU Thermal Monitor.............................[ Disabled ]
CPU EIST Function...............................[ Disabled ]

will this effect my overall performance? or is it going to result in being the exact same?

it will keep your processor from dropping in speed and voltages while idle.if you run it ar 3.9ghz when idle it stays 3.9

No it won't effect your performance.

Hi guys. Just received a new E8400 revision E0 FPO/Batch Q839A219. Is this a good batch? Please share u'r results.

DFI DK X48 T2RSB Plus $159 or
DFI LP LT X48-T2R $189 :confused:

I have 2 4870 512MBs, that is why I am considering a x48 to crossfire. :)

or any other boards? :shrug:

Thank you :up:

well my new E8400 EO Q843A771 vid 1.23 is turning out to be a very good chip.
heres 9x473@4257 w/1.23v
http://i39.tinypic.com/e9zrk4.jpg

Ooo very nice Radaja :up: So u had to sell that E3110?

yep i did and i wished i hadnt,but i needed money.but now its all good,was lucky enough to get a better cpu.thank you god:D

Oh well, still thats a awesome CPU you have now :up:

yea.even though the Xeon had a much lower vid 1.16 it neede 1.39 to do 9x500@4500. this new one only needs 1.32v to do 9x500@4500

Very nice :clap: I wish I had that CPU under my phase change :p:

i wish i had your phase change on my cpu :rolleyes:
im going to have go WC for sure now,otherwise it wouldnt be fair to
this cpu.:D

I was going to get WC, but it would cost $700 to $800 for a high end setup, my phase change only cost $1070. So for an extra $300 I get -50C temps, instead of 50C :p:

that seems pretty steep for WC.im just going to get the 240$ kit from swiftech.

Have an e8400 that I got last year, ordered it shortly after they came out. Ran it at 4.05ghz for well over a year using LLC on a P5K Deluxe board.. Got a quad and a new motherboard earlier this year and had put it away until last week, was bored one night so I thought I would try it again using the Gigabyte board. No signs of degrading after 1yr+ using LLC and countless hour of Prime, IBT, and LinX. I think these chips are a lot harder to damage than some believe. You can see the date in Orthos, 1/23/08 in the first ss. The second ss was a LinX run I did last week in the EP45 UD3P board well over a year later.

BTW that's an awesome 8400 you got there radaja. 4.5ghz-1.328v:up:

How does the newest batches clock?

well i cant speak to all newest batches or E8500-E8600's,but my new E8400 EO, OC's real well.
batch Q843A771 vid 1.237 bought it from newegg 3 1/2 weeks ago
just look in my sig,4500 w/1.32v is pretty good in my book.

On AC?

yep

Damn, you guys are freaking lucky.

In order to get my E0 running at 4500 MHZ, it takes above 1.412 volts. At 4.25 any lower than 1.328 will cause problems. And I bought it in late December. The batch number is Q832A389

Any tips to lower the voltage would be appreciated, I want to keep temps down, especially in this warm weather we are getting over here.

Have you tried playing around with the MCH and CPU references? They have helped me run lower vcore before :)

9x500@4500 w/1.31v:D
i was able to lower my vcore by raising my vtt one notch for this run.
but theres only so much that can be done,the rest is up to the cpu.

fatguy1992 was right about the mch refyou really have to find sweetspot
well i switched my mch ref from 0.750 bios/0.700 ET6 to 0.770 bios/0.720 ET6
and was able to drop my vcore even lower.

radaja - what mobo?

Hes using a Gigabyte UD3R I think.

very impressive radaja

last week I had quite new batch Q830A931 of E8500 E0 and it was bad piece:(it was extra heating, because my Intel stock cooler is cooling my E5200 with 1.65V on 68°C Idle...but this E8500 on 1.28V had 90°C in BIOS and I didn't understand it...first step was with 1.4V, but after reboot was temperature in BIOS 125°C:eek:is it normal with stock cooler? my last E8400 C0 was cooling with this stock cooler on 1.5V and temperatures weren't over 90°C

I'll be getting one this week. Just bought it at Dell for $158 (w/ coupon code) while NewEgg was selling it for $159 then I looked back earlier today at NewEgg and it went to $167... (for the E8400).

I'll post up results when it comes in :).

_AntLionBR_ our congratulations man! using noctua great result!

_AntLionBR_, me passa ( se possivel ) o setting que vc ta usando na bios ai para mim comparar com o meu o 4870@over me passou um mais ta muito mais muito instável e tirei mais agora quando tendo voltar ele não passa nem do carregamento do sistema!!!

Viva o Brasil!!!!!!!!!!!!!!!!!!

radaja, that's a great chip. have you tried max clocks on air for it? tried running SPi 1M at 5ghz? your chip looks very capable of that. and planning to ever sell it at a premium? :hrhr:

thanks guys,it is indeed the UD3R.i was without internet for two weeks
and it almost killed me:D
i havent tried going higher than 1.39v yet.but i will and see how high i can go on air:up:

and as to this "and planning to ever sell it at a premium?" you never know
with my job instability lately,it could very well be on the market at a moments notice

Still breaking in the CPU, got it this afternoon :).

4.0GHz (445x9) 1.248V using IBT
http://img200.imageshack.us/img200/5788/oc40ibt.jpg

Still in testing phase and yes I know I rushed through the lower speeds (will go back to them) but so far 4.0GHz@1.248V is running strong. Going to do more IBT runs.

I think I'm limited by my motherboard and my cooling... Heck its a CNPS9500! lol

Q845A837 bought it yesterday from Dell. :)

Stepping E0 worth every penny paid friend. It was not beyond 4.5Ghz. :D

thank you! how many volts your cpu @ 4.2Ghz requires to pass at least 20 min of LinX/IBT?

Bye! :)
