This has bee a great thread. I read all of it before I set up my P5W-DH and things have gone smoothly. I have a question regarding memory timings. I have an E6400 on this board running at a 430FSB with the 8x multiplier=3.44GHz Orthos stable for 14hrs, 2x1GB G.Skill 6400HZ's @ 1:1=860MHz @4-4-4-5, Memtest stable for 20hrs. What are the benefits from running 4-4-4-5 vs the standard SPD timings of 4-4-4-12? Do I stand a higher chance of getting a corrupted operating system with the tighter timings? dVIMM is set at 2.1v.
