Hi recently i bought a kingston 4 gb ddr3 ram and plugged it in my pc which had another 4 gb in it of kingston 1333 mhz same as this one....now to my surprise everything is running including full-hd movies but not any game at all.i tried it on my friend's but in his case,games run a few minutes before freezing to death.we tried bios update and alll this game we would be able to play before....so other specs should'nt be a issue...as i plug out the ram the game runs fine....i can not get through it....did i pick aa incompitable ram ? the one in my pc was a low profile double sided ram and this one is a high-profile one-sided ram....is this the problem ? Please do answer fast.thanks in advance.
