**Official e8400/e8500 Retail OC Thread

Here is my 24/7 setup:

Hey, take out those foreground pictures/images and let us see what's behind them.

[alex17 GTX]

Nice cpu's you got there you 3 last people...

And all running Asus , that must say something...
my gigacrap sucks on this wolfdale... hopefully premium will cure that

regards.

Not really.

Here is my Q746A E8400 on DFI Lanparty DK P35 T2RS

[IcemaN22]

Good luck testing it. You will be the one who will let us know if it's a good OCer batch or not! So, take out your blade and slice the box open. Go ahead, do it. HHehhehe...have fun!

I quess I have to when no other have this batch
I will give the results when I get back my motherboard from RMA, and I hope someone in the meantime will test this batch before me
Btw, have you guys seen some other tests with Q802AXXX ???

[Furiøùs]

My chip is a Q746A33 its not too good.. everyone i see who has great OC's is using a Q746.. my last 2 digits just suck though, i get 4GHz (check sig for FSB etc) at 1.425 in bios (1.39 idle, 1.37 underload) Terrible for a Q746..

[X4er0]

Just got my E8500, new batch Q807A067, hope this will get me 4,3GHz 24/7 on DDR3 1600 OCZ EB4GK.

Now i'm waiting for the mobo gigabyte X48T.

Here's the highest stable I have gotten so far:



I've taken out two sticks of ram and successfully run 2x2GB of this GSkill at 8x500 in prime for about 8 hours. With all four sticks in though, I can't get much higher than 450Mhz FSB. 460MHz has failed on all my attempts so far. Not sure if I should raise my NB or VTT voltages any higher than they already are.

I wouldn't recomend 1.42V as 24/7 clock. Will it not be stable on lower voltage? Use 1.1V on VTT, and if u can't, use 1.2V, that's enough. NB, 1.5V should be OK.

[Big Lar]

@ UObean You really shouldn't need that high of NB and VTT. Maybe try VTT of 1.12 and NB of 1.45 tops. Also maybe try trfc of 52 and try performance level 8. Thats how I ran that ram on my T2RS anyhow. Also, thats for 450fsb on the ram. Just trying to help.

I got a new cpu here, e8500, Q746A580, needs 1.28v for 4ghz... nothing spectacular so no screenshot
Sucks imho... especially if you see e8400 and e3110 cpus do better...

[Jupiler]

Small update from my E8200.
4200 at 1.296V, not bad at all, I'd say.

[Garrett]

I hate you

[GOZR]

X4er0 where did youy get the 8500 ?

Thx

I water cool and my temps are consistant. I'm not really worried about the cpu voltage as much as I was the VTT. I've since lowered it to 1.2v. I'm doing a Prime95 test on that now, provided it passes like 4 hours I'll probably just keep it here.

I need some help picking a motherboard for when I get my e8400. Right now I am looking at three of them right now.

http://www.newegg.com/Product/Produc...82E16813127033 this abit X38 one

-or-

http://www.newegg.com/Product/Produc...82E16813128089 this gigabyte X38 one

-or-

http://www.newegg.com/Product/Produc...82E16813141005 this XFX 780i one

Also I noticed that gigabyte has two versions of the X38 board, are they basically the same thing but with different cooling and some more cables?

[MrHydes]

Here is my E8400 tray, Q746A482. I am relatively happy with it, it clocks decently but unfortunately cannot do 4GHz with anything below 1.414V real. It does 4.3GHz at the same voltage though.... Haven't and wont try any higher since the CPU sits in a crammed HTPC, which I would rather keep silent than uber-fast.

hwat cooler were you using?

[RunawayPrisoner]

hwat cooler were you using?

Try Thermaltake Big Typhoon? (Not the VX one)
Here are my results using Big Typhoon:



Barely 50C

[GOZR]

If you are using SLI well the Nvidia chip set is a must.

thanks, i'm not asking for advice for a cooler i have tuniq and Zalman 9500 for air...

i just wanted to know what cooler you're using... thanks anyway

Well I am considering SLIing when nvidia releases their real next generation cards or getting another 8800 GT but I don't think I will see much of an improvement till I upgrade my monitor(currently a 19")

[WhiteFireDragon]

Here is a screen shot of mine.

4.3 at 1.33v is pretty good. is that a good batch? or how are you cooling it?

[mrcape]

4200 at 1.296V, not bad at all, I'd say.

That's the best results I've seen for that chip - Awesome! I had similar performance from my e8400 before I beat on it (8.5x500 1.28vcore Prime hours).

The 525 FSB x 8 with that vcore is just great. Just to pick your brain - what did you find helped you get it stable at that low vcore? Was the 1.5v NB helping? Any other findings? How about your GTL settings?

[Darkatom]

Is it worth to get a e8400 when I already own a q6600 ? My 24/7 oc tops out at 3.7ghz with 1.49vcore, i'm thinking that 4.0ghz is a resonable goal for an e8400. Would this benefit me more daily over a quad ? I dont do any kind of encoding.

[WhiteFireDragon]

hmm i don't know how much money you have to spend but if it were me and i already have a q6600, i wouldn't justify a $200+ for the performance gains even though you ususally wont utilize the full 4 cores currently

Own both of them, whichever you want to turn, you have it.

Wow, great!!!
I can't (or can't) get mine to 4G without less than 1,4V
Could you post your batch and voltages section settings please (GTLs incl.)?
Thanks!!!
