Hello everyone,
We had the same problem at the company with 2 threadripper 2990WX. black screen, forced to unplug the computer to restart it
A machine with a motherboard: ASUS® ROG STRIX X399-E
A machine with a motherboard: ASUS® PRIME X399-A
there is exactly the same problem with the two motherboards.
the 2 computers are with Noctua NH-U14S TR4-SP3 and Corsair VENGEANCE DDR4 2400 MHz (4 x 16 Go)
We have solved the problem by modifying the parameters of the ram in the bios of the motherboard.
Here is the link of the tutorial.
My big disappointment with the threadripper is that the cinebench score is good but the rendering with corona is not as fast as with my bixon 2698 V4 ES
bi xeon 2698 V4 ES cinebench: 4200
threadripper 2990WX cinebench: 5000
bi xeon complex corona scene: 1 hour
threadripper 2990WX complex corona scene: 1h50min!
I do not understand where this problem comes from but I find the performance of the threadrippers very random.
