Win 7 Memory Incompatibility

  1. I have a system that can boot Win 2000, Win Vista (32) and Win 7 beta (64). All three operating systems work fine with the 4 GB of Corsair memory but when I try to switch to 4 GB of Crucial memory (CT2CP25664AA800) the 32 bit systems run fine but the 64 bit system hangs on boot. Is this a known problem with Crucial memory or is it a Win 7 problem?

    BTW, the Crucial memory is properly recognized by the BIOS (SPD detect) and it also passes the Win 7 memory test that can be accessed during boot up.

    Found the problem. Intel DG965WH motherboard needed a BIOS upgrade. Got 6 GB working now.
