In preparation for my E8500 processor (on order), I installed some Corsair PC-9136 memory today. However, no matter what I try, I cannot get past the C1 on LED display when starting computer. I tried clearing CMOS, tried both pairs of slots on MB, and made sure to put the new RAM in after returning MB BIOS to factory settings. Nothing.

I can put my Patriot PC-8500 memory into either set of slots, and it works just fine. I really wanted this memory to work, and don't know what else to try. Because it was a special order, I am faced with a 20% restocking fee, and at $449 Canadian dollars, thats $90 out of my pocket. Any suggestions?
