Brand New Memory effecting Display Driver making games lock up?

I replaced my 4 1gb sticks of Corsair 667mhz pc2 5300 to a OCZ Reaper HPC 4 2gb 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500).

Upon the playing of games, most games I would try would result in freezing and eventually crashing my computer.

The error message "The Display Driver has stopped responding and has recovered" would pop up.

Sometimes I would get the Blue Screen of death with the cause referring to a atikmdag.sys file.

This is happening to all the games I have after installing the memory. Do you have any ideas what is going on?

I have upgraded my video drivers and tried to use the advanced boot in system configuration to make sure it was booting at the most processors and memory.

I DID however set my memory speed to 1066 mhz in the BIOS.

Any help with this? I would hate to suffer from this for long.

  1. I have run Windows Diagnostic Memory and it has found no problems with the memory sticks.
  2. What happens when you use the old memory settings?
  3. Actually I just tried it at 800mhz. Seems like it works perfectly. But the downside is not being able to use the 1066 mhz to its full potential.
  4. Maybe there's a compatibility issue? Have you checked if your new RAM appears in your mobo's QVL?
