    Computer hangs/BSOD on restart

    • i7-7700k
    • Asrock z270 Extreme4
    • 32GB DDR4-2400 Ram
    • GTX 1080Ti FE
    • Corsair RM750x
    • Samsung 960EVO 500GB M2
    • Seagate barracuda 6tb x2
    • Windows 10 64bit Build 15063

    I've recently built, delided and overclocked my first pc. Everything was running just fine, until recently, I found out that pressing restart inside the windows start menu will shutdown windows, but will always freeze when it starts up again on the spinning dots. It freezes even if I overclock by 100Mhz. It freezes when I manually set multiplier to 45 even though its a 4.5Ghz cpu. The pc starts up just fine, runs just fine, and shuts down just fine. This only happens when I use the restart option inside windows or when an update causes it to restart itself.

    I have my cpu OCed to 4.9Ghz at 140mV offset LLC3. Under load it's doing 1.28v. Temps never hit over 79C in p95. My OC is stable for 10 Hours p95 blend, 11 hours p95 small FFT, and an overnight memtest86. It has never crashed on me inside of windows.

    Googling tells me that the cpu can't handle the overclock, but I'm passing these stress tests with flying colors. Not only that, but manually setting the cpu to 4.5Ghz results in the same lockup when restarting inside windows. This doesn't happen when I set multiplier to 44 or below, or on stock settings. I've tried updating BIOS from 1.4 to 2.0. I've tried reseating the cpu. I've tried bumping up the SA and VCCIO voltages in 50mV intervals up to +200mV. Nothing works. Most times, it would restart, and get stuck on the spinning dots and do nothing. Sometimes, it would BSOD after getting stuck on the spinning dots (either WHEA uncorrectable or machine check exception) but the pc will hang at 0% as it's collecting an error report. As such, I'm not sure if my dump log is of any use, but I've attached it anyways. I would appreciate if anyone could help me out or share your past experiences if you have resolved this before on your pc.

    I found a fix for this! Originally, I ran into a fix where I changed VCCSA and VCCIO, while giving it a slight bump in vcore and changed cache speed (ring clock) to 4.8Ghz. This allowed me to boot and restart!!!!!! But it would instantly crash the moment I ran a stress test... So I had a computer that was super stable and couldn't restart, and now I have the exact opposite.

    After a bit of testing, I found that changing VCCSA and VCCIO to anything other than stock would cause instability. The key to a stable boot and restart was cache speed. Setting the cache speed to anything higher than stock would require more voltage, so I wanted to see how low I could set this without causing instability. Turns out I only needed to set the cache speed multiplier to 42, the same speed as if it was left on auto... Completely bizarre.

    tl;dr Computer is very stable but crashes on restart. Cache speed if left on auto clocks at 4.2Ghz. Setting cache speed to 4.2Ghz fixes restart problem.
