It's definitely the best real usage test for an FX tbh. Just making the chip get hot with Prime is no way to actually test stability.
That multi tasking test is absolute torture. My rigs can sail through the rest but once I get there I know I'm running a proper torture test. Haha, the amount of times I've sat there nervously chewing my finger nails watching the temps go up and down like a prairie dog ducking in and out of the hole
72c...71c....72c... hahahaha
Ha. Which part is that then? I just set the stress test for one hour and walk away only to check back every now and then to see if all is still running.
