Hello, I have been running 2 x 512 Corsair XMS 3500 on an Abit NF7-S. I bought another stick 2nd hand the other day to fill in the last slot but I am not sure that this extra stick of ram is really XMS 3500 as the PC crashed with the nee-neh siren sounding. I have had to slacken the timings and bump up the voltage to get things going again. Is there a utility that will exactly identify the ram and SPD timings as standard so I can see what is going on. Cheers, PeterT.
