Hello, I have problem with my ram, I have 2x2gb (OCZ 2x2GB DDR3 SDRAM PC8500 CL7.0 Gold Edition)
and whenever I use both of them I keep getting all kinds of BSOD. though if I use 1 it runs fine no matter which one I use, that suggests that they are not broken?

Strange thing is if I stick both and put bios all on default the PC wont even get to windows loading screen.
Im not good with bios setting and more technical details so any help appreciated. like what settings I should try voltages etc.

Also this problem started when I installed windows 7 x64, I had to install it using 1 ram stick otherwise it would crash the installation. only windows xp would install with 4g ram. vista and 7 x84 would always crash.
