Tags: CPUs Memory Last response: December 4, 2008 6:27 PM in CPUs Share vitiris71 December 4, 2008 11:55:25 AM Hey guys thanks for replies on my other post. If I have a E8500 FSB 1300 Intel C2D whats the best memory that I should get to try and get a 1:1 ratio? would it be DDR3 1333? I have a ASRock P45 TS-R but I am switching it out and I hear ASUS P5Q3 boards are really picky with memory I currently have OCZ Platinum DDR3 1333 / 10666 memory 2x2gb is this correct for this cpu? thanks again you guys rock for advice.
