I meant to suggest the other night, go into the Intel BIOS, find the memory settings area, and set it to custom timings, and add a clock to each of the timings, like if its 4-4-4-12, try 5-5-5-15 (or whatever the next increment is). running 8GB on a desktop board, I'm guessing you have all slots full, this increseas the capacitive load on the address and data bus, and makes marginal timing more marginal.
