it seems bios 1805 is having some problems with pci-e 3.0 video cards, or at least with my xfx hd7970. I flashed it with said bios first thing after I get it installed and all was working fine but on saturday the performance really started to suck, moved it into a system with a asrock z77 extreme4 installed and the card worked perfectly and the card from that system, a hd6850 worked fine in mine, moved back to my system and trouble is back, flashed bios to the one the board came with, 1708, and trouble disappears.

just curious if anyone else seen this trouble with their board.

Bios 1805 has many issues, 1708 only has a couple (non sticking multi's - higher voltages, Realtemp conflict etc.)
Needing higher voltages for same O/C may cause probs like crashing/BSOD/Win explorer freezing/Firefox freeze.
Forget about using offset mode - only manual set works as expected.
As you add voltage the O/S gets further along in boot/apps until stable.
1616 is a decent bios and 1504 is golden - no probs.
Per usual, some folks report flawless implementation with 1805, but I was not one of them.
Maybe they wouldnt know a prob if they saw it - lol

was going to try 1504 but the structure of the bios was changed and the flashing software wont let me go back to that, may have to try to force it with the button on the board.
