Can't start the recovery mode.
I purchased a new Gigabyte Z390 pro for my 8700k. Before, I used an Asrock Killer SL Z370 with a CPU at 4.9 and 1.27v per core. After switching to this board, I’m struggling to revert the overclock and the system won’t boot. Even with 4.7v at 1.36v, I see BSODs. If I enable auto VCore, it boots at any speed I try, up to 5.0ghz, but the CPU reports between 1.23-1.34v. Manually adjusting Vcore in BIOS doesn’t work. What could be wrong?
but would I need load line if I'm already over volting the CPU (my understanding for load line is it just overvolts to compensate for Vdroop) like I said when its set to Auto the Vcore according to CPUZ uses between 1.23-1.36 with 5.0ghz all core OC, but even if I set it to 1.38v on Vcore and set my CPU to run at 4.7Ghz all core it wont boot even with voltages set for higher than what the 5Ghz OC needed, it wont boot just BSOD, but if Vcore is set to auto I can boot at any speed and seem stable I used my pc for 24 hours on auto and monitored the voltages through gaming and at idle and things to see what it was reporting so that I could use that to set my manual overclock but then using the same amount as the board was reporting back to me it wont boot but if set to auto then it works fine, I'm wondering if something is faulty on this new board or if it could be a bios issue or if I have over looked some small setting like load line calibration, but I never increased the LLC as I figured I was already overvolting the cpu.
You're looking to achieve a higher voltage output while maintaining a stable core frequency around 4.9Ghz. You mentioned using 1.27Vcore with that setting before and wondered if adjusting the LLC value or Vcore could help you get back to that level. It sounds like you're trying to balance stability and performance.
It seems there might be some confusion about how LLC works and its role in voltage management. If you're already operating above the voltage limit, using an LLC might not be necessary since it's designed to prevent overvoltage. The manual OC voltage setting could be interfering because it might not align with the LLC's protective limits, causing boot issues.
without LLC, entering 1.4V in the BIOS might result in 1.35-1.38V during idle in Windows, and just 1.15V during the stress test. The BIOS input isn't fixed; LLC assists in keeping it stable, meaning it shouldn't raise the voltage too much—so even with LLC, allow a slight drop like 1.4V to 1.35V under load.
I think I can give it a shot and let you know how it goes. I’ll use the old voltage settings plus some extra LLC and see if it boots up.
