Can anyone with 3xxx series Threadripper do simple test and give some feedback? The test is the Prime95 with "Blend" option, here you can find how to https://mywindowshub.com/how-to-use-prime95-to-stress-test-cpu/ . You don't need to run it for along time, just 5-10 minutes, may be less. When the test is started, try periodically to move the mouse cursor on the screen, do you experiencing mouse lagging, hanging, anything else?
Please provide what CPU, RAM and OS you have, thanks!
