Error with VCCSA voltage control. Issue resolved.
Error with VCCSA voltage control. Issue resolved.
the issue started with BSODs, machine check exceptions, and memory management warnings while running BFV. initially, I adjusted my VCCSA and VCCIO voltages to 1v each, which resolved the problem. however, over two days the VCCSA voltage increased after each boot—first 1.108v, then 1.120v, followed by 1.128v, 1.14v, and now 1.17v. when I set it to 1V flat in BIOS, the voltage fluctuated between 1.17v and a few millivolts higher each time. after flashing the BIOS and clearing CMOS, it worked briefly until rebooting twice, then the voltage dropped back to 1.128v and later spiked again to 1.168v. this is on a Z390 Extreme4 system.
a short while after that, I restarted once more and it’s now running at 1.184v
You probably set a specific value in the BIOS and then confirmed it by reading that number.
