newbie overclocking my z170 board and 6700k to 4400 hz using"adaptive" with a +25 offset. ran prime 95 blend test for 4 hours, no problems, but im not coming back from sleep mode, it stays a black screen or kind of reboots when i try  to wake  it up.   wondering if there are any other motherboard setting that i missed?  I watched the z170 eva tutorial on youtube to learn.

So if you have NO overclock whatsoever everything is fine?

Yes, with no overclock everything is fine.   With overclock , after waking up PC, i hear 4 beeps from the motherboard/ and the pc reboots, instead of going right back into windows the way I left it before.

Try a static voltage instead of adaptive.
