Problem with RAM

[nikorr]

I SOLVED THE PROBLEM BY SIMPLY CHANGING MULTIPLIER/VOLTAGE CHANGE FROM AUTO TO MANUAL IN BIOS.

But now i have another problem, when i unlock phenom ii x2 550 in x4 is stable in prime95 but it freezes in games. i know is not from the CPU because this is my second CPU, the first one (also phenom ii x2 550) did the same thing, freezes in games. Is not from the mobo too because on the old mobo gigabyte ga-m720-us3 did sa same thing, the difference is that on gigabyte i get freeze after 1 sec of prime95.

Try to re-install the video driver.
