Tried a little OC'ing this afternoon, and Windows ended up corrupting. This being my 1st time doing this, i was kinda expecting as much. No big deal most of my files backed up. Anyway i have a opty 146 on arctic 64, 2 GB xms corsair c2pt (4x512mb), xfx 7800gt 256mb. Now i got to 2.6ghz ok, tried 2.7 and the whole system was a little unstable, tried increasing the voltage to 1.5 but by that time i think windows had fallen over pretty bad. Now if my fsb is stable at 250 is it possible for me to increase the multiplier upto 11 so that it hits 2.75ghz? Also my psu is a tagan 430w, is that gonna supply enough juice?
 
ye the htt multiplyer is down. Ive managed to get it stable at 2.4ghz @ 1.5v with a decent divider on the memory. Which from going at what other ppl have posted seems a little weak. Although the temps are under 40deg when at load.
Whats the max voltage i can safely put through the cpu without generating to much heat?
 
dont want to go far over 1.5 on air mate :) you sure you cant push it higher at 1.5v? ht at 3 and ram running under the rated speed just to make sure? make sure its running 2t aswell as you have 4sticks.
 
Aye done all that, would loosening the memory timings help out at all? they are fairly tight atm, just cant help getting the feeling its my psu, when i bought it 430w was plenty for what i needed. ill have another play and see what i can do.
 
You need to find each limit on it's own, first lower the memory by using a 1:2 divider and lower the multi to 7x and HTT multi to 3x to find the max stable mobo limit.

Then start increasing the CPU multi to find the max CPU speed with the known mobo HTT(FSB) limit

Then use higher multi's for the memory.

If you do it all at once you will never know what component is limiting you.
