Thanks for the help
Well the voltage is determined by the sticks. The sticks I run are rated for 1.9v @ 1866 with 8-8-8-24 timings. If I set them lower to lets say 1066 they'll run at 1.5v all day long without a hitch. But if I want to run some tighter timings like 6-5-5-15 I need to up the voltage. As for max voltage that once again depends on the sticks. I have taken mine all the way up to 2.1v without an issue (3.5 hours prime blend stable). So it's just trial and error. How much voltage you can run through them is also determined by the IC (integrated circuits) on the sticks. Some like volts and some hate it.
Also, remember what I said before, your memory overclock is determined by your CPU ultimately.
With that said when you are overclocking before you even boot into windows, run memtest for at least 4-5 passes (all tests not just 5 & 8). If you get no errors, boot in to windows and run Prime95
for a minimum of 4 hours on the "Blend" test. It'll test your overall system as to how the CPU and the memory work when they're both under load. I've found that my RAM can run @ 1600 with 6-5-5-15-20 timings all day in memtest without 1 error. But as soon as I Prime95 it, it would fail. I was only able to manage to get 3.5 hours stability out of them. So I decided to drop them to 1333 with the tight timings and up my northbridge. The actual speed difference in negligible, and the throughput is almost identical. So not much of a loss.Edited by BlackOmega - 11/6/09 at 12:02am
