P35 platinum wont post resets after 1066 install

I have had my computer for a while and had 2x1gb crucial cas4 800mhz and had no problem.
I put in 2x2gb pc8500 cas7 crucial in and it just keeps resetting before post.


I have an E8400 stock
OCZ 700 psu
XFX 8800gt at 640mhz FO
500gb sata hd WD and 80gb slave by WD


I went to MSIs website and did the recommended ram and it took me to crucials and it showed the ram I bought. I have tried just installing one stick, no change. I also went into MSI's dual core center and set the ram V to 1.8 instead of the 2.1 my old pc6400 needed, it seemed to know I had changed the ram because it had the ballistix at only 1.9v and it was no longer under my profile.

Do I need to update the bios or something? I am pretty sure I did not to long ago.


Thanks in advance

  1. Use the old memory and set the RAM to manual. Then adjust the timings and voltage to match the specs of the new RAM at 1066.
