**Official DFI LanParty UT 790FX-M2R Review/Overclock/Guide Thread**

[3oh6]

hey cats, as mentioned, i decided to give this board another try and things have been going really well after exchanging with that board stuck at 133MHz. that is until i reached 281MHz HTT. 281MHz HTT is Prime/3D stable for hours on end, never a problem. going up to 282MHz HTT results in a hang at 25 during POST. this is with two Phenoms or the 3200+. same exact results with all three. BIOS i am running is the latest official 01/30 FWIW.

i would like to see if i can get above 281MHz HTT in Windows but not sure which version of AOD or ClockGen will work, any advice would be great.

obviously i would also like to get past this spot from within the BIOS as well. i have tried pretty much everything in Genie BIOS section and can't get 282MHz HTT+ to POST. here is the timing sheet i am working with right now, any help would be appreciated:
