Overclocking my 955

post #1 of 17
Thread Starter 
So I am making runs at OCing my Phenom 955 and I've encountered some glitching. The motherboard was set to 1.475 v, droops down to 1.46 at idle and 1.39 at load. This was relatively stable, 30 minutes core damager, 3+ hours of CoD4, but BC2 crashed it. I am at 3.8 GHz. I want the OC to be stable, but pushing beyond 1.475 might be damaging? I like to keep the FSB at 200 MHz and I do not mess with the RAM at all. What you guys think?

My 3.8 OC was also able to handle 2 hours of constant Crysis runs, but it can't do more the 5 minutes of BC2.

None of that sounds right tbh. You can turn off VDroop btw, its usually called Load calibration, thats whats causing the vcore drop on load. But that voltage doesn't sound right either, its on auto or what? im @ 3.6 atm as im waiting for a cooler, but i only need to use less then 1.25 volts for it.

Edit: Have you checked if that PSU is sufficient for sli 470's? could be why its giving you trouble trying to OC. Just a theory of course. Although its probably fine tbh.

Over 1.475v isnt damaging, and considering you have a Vdroop of 0.085v, you're safe to go up. Vdroop is not a glitch, just your motherboard not being that good. Mine has a Vdroop of 0.05v..

But 3.8 GHz w/ 1.39 should be fine, I worry about he idle voltages being to high. If I jump the voltage to 1.50 the idle will be 1.49 and it would load around 1.44, those votages, from what I've seen are for 4.0 GHz+ OCs. I don't see why my chip requires so much volts, your x6 only uses 1.35 for similar clocks.

And the M4N98TD EVO is the best AMD/SLI motherboard you can get still. MSI used to make a GD80 980a, but I didn't see it anywhere when I upgraded.

How could BC2 fail the OC when all my other applications run fine?

By crash did you get a BSOD? Black screen? What type?

Wait. It's only BC2 thats giving you trouble? lets clear this part up first. I thought it was BC2 that identified the problem. If its just that game giving you trouble then it sounds like a compatiblilty issue. I stand by what i said though.

That voltage is too high. If its one game crashing you, upping the volts wont do anything for it. you should be trying to lower them. And test with a neutral program, like AMD OD, Prime95, OCCT, Lynx.

Not all CPU's are created equal, so some might require more voltage and some less. Phenom II hexacores generally overclock better than the quads.

Asus is good, but they had an unfortunate run with the Vdroop I guess. BC2 probably fails because it is very CPU intensive, and uses all your 4 cores. To make sure you are stable run atleast 8+ hours of Prime95.

The only other program he said he used was Crysis 2, and it only uses 2 cores, thus making it able to run at less voltage.

BC2 = Bad Company 2 produces a BSOD.

I ran Crysis Warhead, not Crysis 2.

I will run Prime95 later tonight when I get back home, which mode? I assume blend?

As for the PSU question, this is a Corsair TX750W. According to eXtreme PSU calculator, I am fine.

I doubt the voltage is too high, I only use 1.39 at full load, Core Damager for 30 minutes.

Can anyone recommend me a setup, FSB Multi Voltage. I've heard that I should also check my RAM and NB? I leave those at Auto, so they shouldn't cause issues.

BC2 can be used to test your oc stability. I always test my oc by playing BC2 even if it pass 6 hours of prime95. Just my opinion though.

I always run Prime95 blend test for 10hrs, furmark, and 3dmark vantage. Is your processor a c2 or c3? If its a c2 you probably have to push for 1.5-1.55 for a stable 3.8ghz+
