Just updated to the 1.20 Bios..I am running 2080ti in SLI...If I have my monitor plugged into the "top" card I can see the boot screen and get into the BIOS, but no visibility to windows. If I have the monitor plugged into the "bottom" card I cannot see the boot or bios screens, but I can see windows...Any idea on what might be going on? I was on the 1.11 bios and did not have this issue. I am using display port.
Just to follow up on this,,,I found out what was occurring. I originally in the bios had the Windows OS set to "not" WHQL. As soon as I enabled the WHQL windows setting (which I had to do to setup my new RAID-0) it started working as it should...
I'm having a lot of issues. not with the temperature that doesn't seem to go higher than 64.
But on significantly heavily multithreaded benchmarks the computer just kind of goes into a mode where is unresponsive I have a zenith extreme alpha motherboard.
Is it possible that the power supply is having issues drawing enough current from the outlet?

There is a concept of "good core" and "bad core". The difference in operating voltage can reach 0.1-0.15 volts. Here's an example for the 2700X
My sample 2990WX has some bad cores that hold back overclocking, for 4 GHz they need 1.3 volts.
The second problem is a weak power system. You need to cool the VRM to 35-40 degrees to keep this kind of overclocking. The values that you can observe in the datasheet indicate ideal test conditions that do not exist in reality.
If you want to calculate the current limit for a working stand, you need to divide the value by 2 (there are many factors, if you are interested I can tell), which is indicated in the datasheet. For example , IR3555M 60A / 2 * 8 phases = 240A. At a frequency of 4 GHz, the typical sample 2990 requires 272A. Draw conclusions
