It very well could. Won't know till you try it

Plus do you have the latest bios? Sometimes a bios update can help. "Sometimes"

All this work to go from 2.75Ghz to 2.8Ghz? A small 1% difference in speed? Id keep my memory at the faster speeds and my voltages slightly above stock and call it what it is. Not work risking it for such a trivial difference IMO. I love overclocking but just like drinking.. you gotta know when enough is enough You probably just hit your limit. Any good overclocker knows... you reach the point where its unstable and your system is at its max and take it down just slightly.

Well actually im at 2.7GHz and i want 2.8. I can't even get stable at 2.75...

Would you say I got a bad CPU? I though I had a good stepping - CCBWE...

Sile, yes i am pretty sure i have the latest official BIOS (v1009), I wouldnt wanna risk a beta.

I'd say you have a decent CPU if you can get 2.7GHZ. Always remember that anything you get from an overclock is a bonus. You bought the chip expecting to see stock speeds, and anything else is a bonus. It doesn't make any sense to buy a slower chip a expect it to clock as high as any others. Your processor might not even overclock at all, and the one that was made right after it might hit 3.0GHZ. As long as it reaches stock speeds, then it is a good cpu.

Very true. A good example is we both have the same cpu. Yours runs stable at 2.8 with 1.5. Mine runs stable at 2.912 with 1.4. It's all a mixed bag.

HEY GUY'S!! Good news (for me)! It's not my CPU that can't go further, it's my ram! I just tried dropping my ram down to ddr266 (giving me only 160Mhz) and i passed prime with a cpu clock that i could not pass before. Is there a way i can tweak my memory (voltage increase..etc) so that it can run back to speed and still let me go higher?? I getn excited now! Plz advice!

Default Re: Need some help getting to 2.8GHz with my A64 x2 4800.

Folks sorry for resurrecting this thread, but I need some critical advice. I am closing in on 2.8GHz (already sable at 2.75) and in order to have it stable I will require more cpu voltage. Now right now the i have it at 1.5v (fluctuates to 1.53) according to cpu-z, although oddly i set it to 1.47 in bios.

Can I increase the vcore more from 1.5v safely? Temps are not an issue as i only hit 45C at the mo.

I run my x2 at 1.53v currently. I've had it as high as 1.57v with no problems. I have been trying to hit 2.9ghz for 3 months now. I was 16 hours prime stable at 2.75ghz @ 1.51v. These chips seem to hit their max around the 1.5v area. Anything much more is a point of diminishing returns. I'm sorry to tell you but pushing it any farther with raised voltage is undue stress man.

You could probably run 1.6v through it but I wouldn't go any higher than that on air. I just installed a watercooling system in my PC and refuse to go over 1.55v. My idle temp is 29C and my load temp is 37C with my system at 2.8ghz. In order to hit 2.85ghz it requires 1.59v and to even get into windows at 2.9 it requires 1.67v. Unless you've got money to burn you've likely reached the max of your chip.

But to answer your question as you intended. You can likely increase your vid up to 1.55-1.65 safely as long as temps are managed. Not guaranteed though.

rHy0 - you should check out this site: www.diy-street.com - specifically take a look at the overclocking guide. Looks like you are about to find your max CPU but once you do, you need to try and find your max overclock on your ram. I am still puzzling this out myself (working on a 4200+ x2 AM2) but I have gotten my cpu stable at 2.7 and my ram should stabilize around 384Mhz according to what I have seen so far (still working on the ram). Give that guide a shot, it is pretty comprehensive.

Use memtest86 when overclocking your ram.

It'll tell you if it is stable or not
