I recently rebuilt my computer and everything is working fine except my ram. CORSAIR 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory It is only reading one of the sticks. It is also reading it at 800mhz, or whatever. Can someone help me fix this problem thanks. I also have 2x 8600 gt video cards. I have an SLI bridge. How do I run dual SLI with them? Do i need a program or something? Thanks in advanced.
