You can try adjusting the clock drives, they should certainly be safe for testing. I seem to have set them to ensure the motherboard's stability at 200BClk
Also - you said you have to reset the CMOS to recover - this board shouldn't do that - it has dual BIOS.
EDIT - are you sure your 3.3v battery is good?
EDIT EDIT - Try with all c-states on and turbo off. Set the volts to mine and bring the BCLK up 10 at a time from stock. You may wish to adjust the Uncore ratio....
Good luck, i'll check in tomorrow.
The CMOS battery metered at 3.166V so it should still be good.
I tried using your settings for the clock drives and it didn't change anything, still wouldn't boot after changing the uncore multiplier. c-states and turbo set like yours didn't change anything either.
When it fails to boot, the debug LED loops between C1 and at least one other value that is too quick to read. Could the looping be keeping the backup BIOS from taking over? I have no idea what they use to determine when the backup BIOS should run. (That is the correct link for my board, got the model and revision off of the board)
EDIT - Tried all settings matching yours, except BCLK at default of 133 and it still wouldn't boot, same C1 loop Edited by kap62 - 8/7/16 at 4:22pm
On the UD7 Rev 1 a C1 Debug code is:
[yes that's a R2 manual but I just looked at the R1 as well]
This makes me think we should check the memory situation - maybe try one stick of RAM, ensure your "Performance Enhance" BIOS setting is on standard and manually set your timings. Ensure "Command Rate" is on 2t as well. Edited by gofasterstripes - 8/8/16 at 12:43am
