How much voltage did you use on the OC?

Ben, congrats on the 4.1Ghz OC

Has stress testing proven it to be stable?

Good luck

I can do a few Benchmarks ... But anything near a Stress test and it will fail.

On air with my setup I cannot see 4.1ghz being stable, 4ghz I can see but it's just not worth it to me.


I have a Dice pot coming.... But I think after my session with Dry Ice I am just going to keep it around 3.8ghz and Just enjoy my Foxconn Destroyer setup.

It's always fun to try to get an OC higher, But at the same time I miss out on what I bought all the parts for in the first place LOL (Gaming!!)


Maybe I will get around to playing on the A79A-S


I forgot to mention the vcore for 4.1ghz : vcore 1.55v


With cooler temps you don't need as high a voltage

I have tried some OC-ing with my new WC setup (http://www.overclock.net/computer-ca...ml#post5923220), but anything past 3830MHz (1.55V) just don't want to be stable . What ever voltage I put on it.
I did brake my previous OC. LOL, with just some minor MHz.

im not 100% sure on this one but i would try and lower your voltage thats pretty interesting temps when running at 3.8 ghz for that kind of water cooling im almost wondering if maybe the high 1.55v is too much heat generation for the tec on the freezone elite? from my understanding this cpu benefits more from lower temps when ocing than higher voltage's so maybe just maybe if you can get that cpu to boot at around 1.5v at the same settings you might be able to take it further? i know my 940BE on my water setup without running a tec yet its in the mail lol. i can reach 3.9ghz and my temps are around the same as your freezone elite and im using a thermal take bigwater 745? i hope any of this rambling helps you out a bit?

You know... I'm running about 33 idle, and 48-50 on full load on all 4 cores with 1.5v and I've got a pretty solid setup (dual rad, 655 pump, gtz block, etc). And that's running in a HAF. I'd attribute it more to the individual CPU than I would the setup.

This setup on a 9950 with the same core voltage would run 10 degrees cooler. The only difference was the cpu.

Yeah, using Freezone Elite, and added a TFC XChanger 240 dual rad into it, made my load temps drop with like 5C-6C. Got it running 24/7 @ 3.75GHz with VCore 1.47V. Runs nice and cool, and with 100% TEC load I can cool this baby down to 29C idle. At Load it runs 48C.

I have tried numerous kind of voltages, for the NB and cpu-NB. couldn't get 3830 stable at first, but then raised the cpu-NB a bit and it was stable.
Dropping the Voltage will result in an error on OCCT or even a BSOD, I am possitive. But I can always try, but I doubt it will do any good though...

Thats kind of high temps for full load unlease my big water 745 is doing a extremly good job of taking away the heat but i also have my 4850x2 in the same water loop. my full load temp at 3.8ghz and 1.55v was only 39C am also doing a straight multiplier overclock i am leaving the reference clock stock. to me it seems like this cpu will oc better with just adjusting the multiplier and trying to use the least amount of voltage per clock possible. oo and are you using vista or xp? seems like everyone so far has noticed it does take extra voltage to oc on vista and stay stable.

Im using the cacvc ac 0851cpiw chip too so maybe there is a slight difference.
