Possible ram timings problem?

[Jake0]

Hi guys,

I've recently upgraded my cpu (from C2D E6600 to C2Q Q9450) and have been having problems ever since.

First I was getting errors within seconds on Prime95 along with application crashes and blue screens. So after sending it back, having it tested and it being fine, I bought a new heatsink + fan and raised the voltage a little and it *seems* to be running stable on low ram usage in Prime95 (1st test option).

Now when I try and run the high ram usage tests it errors in around 3-6 mins.

I've got 4 sticks of ram, 2x1GB Elixir stuff and 2x2gb OCZ Gold.

I've tested each stick of ram one by one and they still error..

Is it a memory timing problem? I've tried multiple timings: 555 - 15, 555 - 18, 555 - 12, 444 - 12 and they all seem to error.

Any suggestions?

p.s the ram was running fine with my old cpu, even after trying the new cpu, then replacing the old one (with cmos resets each time).

thanks in advance!

its probly due to mixing makes and sizes of ram, its generally a big no no

thanks for the reply, yeah I thought the same. But they've been running fine for months now with the old chip and they still error when testing each stick individually

i would try just the ocz memory and make sure you set the required voltage for the memory in the bios

I've tried them on they're own with a voltage on 1.9 (which is stated on the side of the stick) and same errors in prime
