What are some methods I could try to stabilize the overclock on my PII 940 at a lower VCore? My sig is out of date actually... I was running 3.8GHz at 1.475V, ran it on OCCT 3 Linpack for some time and everything ran fine, but then the next day I go to boot it up and the thing blue-screens on Windows startup. Lame. So in any case I bumped the VCore to 1.5 volts. What BIOS optimizations can I do to lower this and still stay stable? NB and HT are both at 2.2GHz, Memory is at 2.1V and 1067Mhz, ACC is on Auto.
thats right, but if the NB voltage isn't high enough, then it should be simple enough to see, such as continuing explorer.exe crashes one right after the other. i haven't had to fiddle with HT voltages before, so i don't quite know how well that would work, memory voltages only affect the memory in AMD cpus. if you want, memtest 86+ to test memory.
some of the few things that affect overclocking the most are
C. specific chip
E. luck of the draw
D. Temps (high temps usually mean higher voltage required)
those are the main things to look out for when overclocking. (list not in order of inportance)
