Any x2 4400+ users able to reach 2.8ghz prime stable?

[GRAFiZ]

If so, what kind of setup did you use to achieve this stability?

ie, cooling, mobo, ram, bios settings, etc.

Any type of info would be greatly appreciated!

Thanks!

here is a screen showing voltages, settings, etc.

I like!!!

How does it respond to the high voltage? Have you seen any stability problems from that type of voltage?

I'm using water right now, keeps my temps pretty low and I havn't gone over 1.62v as I'm just a bit afraid to, should I bite it and go for the gusto?

What type of temps should I be worried of hitting? Would say 55c be too high for that type of voltage?

Thanks for the help bro and congrats on the overclock!

Your going to find at some point increasing Vcore doesn't yeild any further gain in OC

I've not had any problems with my 4400+, this rig stays on 24/7 7 days a week and have never had a BSOD, program drop out, lock up, or whatever. 100% rock solid.

I'd say use the 704-2 Bigtoe bios, your limited with it to 1.72v

I've given the 3800+, 4600+, and this 4400+ all over 1.7v without problems

4400+ @ 2x2.8 GHz rockstable 24/7

It's working at that frequency for a couple of weeks now without any problems at all.



2900+ MHz is possible too, but I don't like the +0.1V VCore increase just because of 50-70 MHz. Therefore, I use this setting for benchmarking only.

[GRAFiZ]

xxmartin, wow! That is one hell of a chip you have there!!! I wish I would luck out as you have sometime down the road with a future chip.

Congrats!!!

Also, to Major, well, tried running the chip at 1.7v, 1.695 during load and it didnt really do much but increase temps.

I tried several different settings, 10x280 1:1 3:2, etc. as well as 11x254, along with many different voltage settings and the like, but alas, all I could achieve was around 20 minutes of dual prime, after that core 0 would always fail. Core 1 keeps going for as long as I let it, but the first core just wont give it to me.

Perhaps I'm missing a setting to achieve stability, but, who knows, I imagine better cooling might help.

My water setup is decent, but nothing special, with it at 1.7v under dual prime 100% load in a room that is near 80f I would hit 58c from time to time.

Right at the limit of what these chips are supposed to handle.

It was worth the try and thanks for the idea!

Heres mine..

Note: It wouldnt do more then 2750Mhz till i poped the top off.

My goal was 2800Mhz dual stable and i think i might have it.. I think your have a better chance with newer chpis after week 25 though.

click refresh or cut and paste if it doesnt work

[eclypse]

chinkgai, cant see the pics.. refresh nor cut and paste are working.

[chinkgai]

sorry about that...disregard those links then...looks like pics.bbzzdd no longer has xtremesystems on their "white list"

here are working links:

Very nice there chinkgai! Whats the week and stepping of that cpu? What cooling?

[Gaspar]

Well it seems you guys have some good chips there. I can do 2.7 so far p95 stable at 1.62v core 1 though fails any higher. though I havent really pushed the vcorr above 1.65v either. Are you guys using clockgen or the bios to reach these speeds???

[eclypse]

bios.. Mine needs like 1.6v just to do 2600Mhz stable.. well on the second core.. More volts baby!

My 4400+ on air (xp-120 high speed panaflo) did 2.6 dual prime stable @ 1.55v. I went up to 1.6v and it didn't seem to help much. Temps were 45C full load.

With the vapochill I've been having a hard time finding a high dual prime stable clock.

I've been doing a lot of testing. I just figured out that a 5:6 ram ratio will make prime95 fail after exactly 24 minutes. The other core always continues. I thought something was up when I saw it fail always at 24 minutes... So now I'm testing with 1:1 going from stock volt and upping it slowly. Wasted so much time testing!!!

With stock volts and mhz I idle -28C / evap @ -50C. Full load is -21/-23C evap @ -48C. 1.8v with dual prime @3000mhz produced way too much heat. 22C cpu and evap @ -17C. I shut it off. I would stay away from more than 1.75v~. Any increase in voltage really affects temps in my case.

With 1.73v I can bench up to 3100mhz. With 1.80v I can bench up to 3150. Anything above 1.7v just seems to add a lot of heat. Windows will boot up to 3200 and it's really unstable.

So far going from stock (Dual Prime Stable)

1.33v = 2400mhz @ -22C
1.33v = 2500mhz @ -20C
1.38v = 2600mhz @ -18C
1.55v = 2700mhz @ -10C
1.55v = 2800mhz @ -10C (90min dual prime so far)

I was hoping for 3ghz. I'd take 2.9 at this point.

used with whats in sig.
edit : btw, those are LARGE FTT primes. not blend and small. Go Large or go home! J/k, honestly I hate prime, but they don't have a dual 3dmark test so..... I guess prime on large ftt's is the next best thing.

the key for a good OC on X2 is to take off the IHS.
