I was on the 1.11 bios and did not have this issue. I am using display port.

Thanks,

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...

Anyone attempting to overclock 2990wx to 4.2?

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?

What is your OC setting? It seems the voltage is not enough

The jump from 4.0 to 4.2GHz is not worth it IMHO. The voltage bump required for that is too high. I run 4.0 @ 1.264v and it's super stable. You'd need to go way over 1.4v to get 4.2 stable.

I've got everything tuned up. I've tested it ranging from voltages, stepping up progressively all the way to 1.5v.

I have tried combination of LLC from Level 4 to Level 6.

I've maxed out the VRM frequency. I've increased the Current to 140% and max on everything.

I've maxed the phase on the VSOC voltage and frequency.

It shuts off when I try to run geekbench in the multicore part.

I'm not really sure what to do.

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

good core
Spoiler!


bad core
Spoiler!


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

Does updating the bios remove profiles?

It does not remove them, but you will need to create new ones...older bios profiles will show up, but will not work with newer bios.
