I keep running into the same memory issues over and over again. 3.99gb usable out of 6 on a cold boot. I have to redo my bios settings and then redo my overclock every time I cold boot. This is after a cpu, motherboard, and memory replacement. As well as a mix between the 3. Seems to be fairly common on x58. I'm over it.
It even does it with everything set to stock.
