I had bad luck with Corsair TWINX512-3700 and returned it to vendor. Setting was at 3-4-4-8 as recommended but WinXP was not stable and applications shut itself down numerous times. Thought that Corsair is good brand. I am not into overclocking so what is the best memory out there for this board that can run at CAS2 and default stock speed. I am not looking at Kingston HyperX 3500 modules. Thanks.
