System restarts under heavy GPU load?
Hi, I recently got an MSI 2080ti Sea Hawk EK X, it worked fine but temps were quite high, I could get it to like 35 degrees over liquid temperature so I opened it up for repaste with liquid metal.
The first time I did this temps didn't improve at all, if anything it got a bit worse. And I had problems of the computer just resets with no warning and no error after the restart, except for Windows saying it was an unexpected shutdown. My theory was that I didn't apply enough liquid metal, and some parts of the die was not actually getting contact, they over heated, triggered some temperature sensor and caused system reset.
So I opened it up again, added a lot more liquid metal. Of course I know this is conductive so I basically built a wall around the die with non-conductive thermal paste, completely covering all the resistors around the die. I also added additional littler washers for more mounting pressure and pressed the block harder into the die. This time temps were much much better, I'm seeing like 10 degrees delta even at 400w, and no resets during gaming for at least 2 hours.
However I noticed that I get instant system reset, the same as before, if I run Userbench? as soon as the graphics test comes up it's instant system reset? I then tried furmark and it too caused system reset in a few minutes, where as it didn't a couple of hours before? I'm pretty sure I did ran furmark for like 5 minutes before and it didn't reset. Also the game I was playing was Total War TK, it could pull 300w just like furmark, and again it didn't reset the system for two hours.
I'm going to try the game again now, maybe something changed inside the graphics card that's starting to cause problems where as it didn't before. Or could it be a software issue? Cuz I mean the Userbench crash is just instant and guaranteed even from a cold machine. Except I could run it no problems with -1000mhz clocks and 50% power, so it absolutely has to do with power?
BTW I'm running a Seasonic 600w 80+ Titanium fanless, it does have airflow in the case I made sure of that. It's a bit low compared to the tradition but I mean the graphics tests that are giving me problems don't stress the CPU that much, if anything you'd expect the games that also stress the CPU to be more problematic on the PSU right?
