Hey there,
I'm trying to overclock my 5820k to around 4.5gh for my 3090. I've looked at two guides:
https://forums.evga.com/EVGA-X99-Quick-O...08949.aspx
and the YouTube video: https://www.youtube.com/watch?v=VnQHm9ZRXw0.

My problem is happening. I can adjust the multiplier, but changing the voltage causes it to freeze during boot and display error codes 39 or 40—none of which are listed. I switched to adaptive voltage and set an offset of +25mV, but that also didn't work. I tried setting the target voltage at 1.1v, but it still failed to boot. The manual doesn’t give clear instructions on how to increase voltage safely. Any advice would be really helpful.

Best,
Bossyfins
P.S. I checked if the PSU is the problem, but it isn’t.

The 5820k requires more than about 1.3v at 4.5ghz, my 5820k worked fine at 1.28v for stable performance, and 1.33v for 4.6ghz which felt a bit hot for my 360mm AIO. The 5960x needed 1.26v at 4.5ghz and 1.32v at 4.6ghz, still a bit warm on an EVGA x99 Classified. I wouldn't exceed 1.35v on the CPU with Haswell—Broadwell behaves differently, so I won't follow those guides. I wish I could assist more, but it's been a while since I tried overclocking on x99; 1.1v is too low for 4.5ghz.
