If you set PCI-e to 105 will the problem settle down?
I ran a 3870X2 and experienced this problem, setting PCIE to 105 resolved the issue and I gained a few extra points in 3DMark, runing my 4870X2 I never had the issue

Board is fussy for sure and I found the later bios's were not very stable nor offered anything 802 is still thebest bios to date imo in terms of stability and bandwidth, flashing to Rampage is a benefit better memory options and better latancy, will it void your warranty, doubtfull as I have RMA'd 2 board flashed to Rampage bios and never had an issue with Asus about it
Thanks for the input, I'll try the PCI-E setting tomorrow or the day after.
