what does a 0000000000009c BSOD code usually mean? i get this when the windows loading screen is shown.

vcore = 1.35v
qpi/vtt = 1.355v

200 x 21 = 4.2 ghz

Are you running the memory at 1640Mhz?
At 1600Mhz (8x) memory my ud7 usually sets the uncore to 3800 (19x) on auto, try manually setting the uncore to 17x.

im actually prime testing now @4.2 200x21
i upped the pll voltage a bit and the IOH and one other voltage a bit and was able to get to the desktop. 1.39..vcore, i think ill be able to drop this because i upped the qpi vtt to get it to boot and i dont think it needs that much vcore to be stable.

my memory is at 1600 mhz now.

so we will see what happens.

Is a qpi/vtt voltage of 1.49 too high?

i am on water and load temps are right at 70C. those temps should drop as i fine tune the vcore.

i want to fold at 4.2 so this would be a 24/7 thing. is this safe?

Normally is around 1.4-1.44V for 200BCLK but if you can't get it stable with less. If you loosen your memory timings you might be able to drop it slightly by reducing the stress on the memory controller. Are you running your mobo in standard, turbo or extreme? Try standard or turbo if you have it in extreme mode as again it directly effects memory performance. I have had trouble in the past trying to run in extreme mode.

well prime ran for 12 hours without any problems. im at 1.35 vcore in the bios and 1.326 in cpu-z.

im almost tempted to try for a higher clock but i think ill leave it for now.
