That is my problem I cant run this sticks with 2.5 or 2.6 volts...

@ bruce
Dammned this was my record Which stepping ? You did some more mhz than my result.

I cant tell you the real differences between 330 @ 2.5-4-3-5 and 285 @ 2-3-3-0 because i cant test that yet. But i believe that it will aproximatelity the same.
