Hi.
I have a new system with the above board, an i7 2600k, and I had a single corsair vengeance 8gb kit 8-8-8-24@1600mhz.
I purchased and installed a second identical kit, and now I get this message on boot-up every 3-4 times, and mem speed is reset to 1333@9-9-9-27. Mind you, when I get this, all I need to do is enter bios and save settings, and it will boot normally and work flawlessly, even under stress tests and gaming.
I am using the F7 bios (latest for the board, I think), and have tested the ram to a reasonable level (4 passes, not 10).
Is this a common problem with an easy solution?
