I can run my system stable at 5-4-4-8 ram timings. The ram runs at 4-4-4-10 in windows just fine but Prime95 gives me errors an hour into stress testing. With it at 5-4-4-8 I get no errors. My question, is it best to run it at 5-4-4-8 or better at 5-5-5-15? Not sure ifs its better to have the first three #s the same. The ram is 4-4-4-12 timed by default but since I overclock my mobo bus to 1600Mhz, Prime95 gives me errors at original settings. I appreciate any advice.
