I didn't have any problems with Cat 9.5 and just dumped those for 9.6 and so far they work fine as well. Also flashed to BIOS 905 today and it seems to be working fine here. Haven't pushed the overclock, the 940 is stable at 3.8Ghz. Should be cooler later this week so I can see if it will hit 4.01Ghz like BIOS 901 allowed. Wish I had A/C in the room would try it right now.
