There is no review anywhere that benchmarks 4x512mb sticks on a 939 board but I know someone out there must be running with this config! All I want to know is how fast you can overclock your memory at 1T command rate. If you set your memory to 1T, how fast can you run the FSB and at what ratio/timings? Someone help please! I really need to know if 4x512 fast sticks are quicker than 2x1GB.
