Okay, so I've been reading a lot in this thread over the last two days trying to stabilize my 2500K overclock. I only just got into overclocking this week, so I'm not too familiar with everything yet.
I managed to get it stable to 4.2GHz at 1.29v vcore and 1.709v (I don't know why my motherboard only has these weird increments for voltage) PLL passing the 1344 and 1792 FFT tests.
I followed the guide in this
thread and my settings are so far the same, except that I have disabled Spread Spectrum to get 100.0MHz Bus Speed.
Once I hit a stable 4.2GHz I upped it to 4.4GHz and started increasing my vcore to get it stable. So far I've gone up to 1.35v and it still crashed after about 8 minutes of Prime95. I just can't believe it needs this much voltage just to run 4.4GHz while I'm seeing others with similar voltages do a lot more.
I tried enabling Speedstep and set the Additional Power Limits to 250 each and the Additional Turbo Voltage to +0.004v. This doesn't help me, and I still crash after around 5-8 minutes.
I also tried increasing my PLL voltage with no results.
Currently trying out different things but my knowledge is limited, so any pointers would be great!
EDIT: Running again with the same settings, but disabling Spread Spectrum (Setting Bus Speed at 99.8MHz instead of 100) seems to work, but it's clocking around 4390MHz. Maybe this is just aesthetics, but can this really be the culprit? I would like it to stay at 4400MHz because 4390MHz doesn't really qualify Edited by Infrantic - 10/19/11 at 1:09pm
