Prime for me would lock up within 5 minutes on large ffts...might be a ddr3 thing tho...I did have flickering on all the 'intro' screens for Crysis, COD4, etc, but gameplay was pretty good (except for random system reboots/lockups, which is what drove me to start agressively tracking this problem down) and now that has gone away...Crysis on all High settings with 4xAA is sweet, tho a bit jerky, I havent OC'ed my 3870's yet, still playing with the memory timings and such.

I too searched far and wide on the net and could find nothing on this issue, some days it sucks being on the pointed end of the stick When it was happening it felt like an IRQ conflict from back in the day, and that was where I first concentrated my efforts, but for me its something with that 2nd set of sata ports. Maybe mine are defective, I dunno...be a good reason to rma for a 1.1 board tho

So far the only thing extreme about this board is the amount of time it has cost me just to get it to run near stock speeds...
