I upgraded my RAM from 4gigs to 8gigs. I bought exact same ram cards I had before (Mushkin DDR2 1000MhZ)
I had 2x2gb kit, I just bought another one.
I put those in and I got BSOD, tried changing ram clock in BIOS...still I get BSOD.I checked them with memtest86+ they work fine they just can't work together
