Just a heads up for anyone who has this board:
The BIOS memory timing options are off for some values. I've been trying to get my RAM set to its 4-4-4-12 timings for a week now, but have been seeing odd readings when I set it to these values in the BIOS. After some trial and error, I have figured out that tRAS is actually 3 higher than the actual value and tRP is actually 2 higher than the actual value. i.e. setting tRAS to 15 in the BIOS actually sets the timing to 12 and setting tRP to 6 in the BIOS actually sets the timing to 4.
This is with the v1.2 BIOS that the board came with and there is a v1.3 BIOS I haven't tried yet, so it may fix the problem. But if you've just got the board and are trying to set your mem timings and seeing weird results, this may be your problem.
I'm not sure if any other mem timing values are off as I've left them to auto. I was just finally happy to see 4-4-4-12 on my Geil PC6400 and it does 880 mhz no problem at these timings.
