I used to have the CL8 Vengeance Corsair kit switched over to the 9-9-9-24 G.Skill kit that was on sale for 30$ but having some random crashign and whatnot this ram saysa it was designed for p67 which is why i put my older ram on the p55 pc i have but i might have to switch back if this one is causing a bottle neck if both are running xmp 1600 does the timing make much differnce? (not on paper etiehr i mean real world..) which would u use
