Have tried two DX79SR borads with 64 GB RAM, Corsair CMZ64GX3M8A1600C9, 8 x 8 GB, PC12800, 1.5 VDC, and each time I insert the last memory module either in C1 or D1 slot, both boards show memory error (3 long beeps). Abolute constant behavior, no overclocking, have tried 1600, 1066 and 800 MHz, have swapped memory, nothing helps. Corsair writes: "It sounds like the motherboard is not capable of handling 8-up configuration at all. Have you contacted your motherboard support team yet? Thank you." The CPU is an i7 3930K and the power supply an Enermax Platimax EPM600AWT. First question: Are people out there running this board with 64 GB and if yes, with which brand and type? Second question: Any suggestions what could be wrong?
