Hi, my brand new MSI RX 580 ARMOR OC 4GB was hitting around 88C-89C when gaming out of the box from day 1. Soon after, it started black screening and i had something to do. I used Radeon Software tuning for custom fan curve, fans were set to spin 100% at 76C and it still would get to 85C under load and black screens would still happen time to time. So i compromised performance and set power limit to -40%. I would get around 76C under load with fans still spinning to almost 100%, but now it was safe so i left it there. It would run like this for months...
Today, i decided to change thermal paste. I used my last sealed/unused thermal paste from around 8 years ago. I kinda used much, but i guess it's Ok. Temps went down quite well. I removed power limit and left fans at 100%, now i was hitting around 80C-82C compared to 88C-89C , but it was still too much for me so now, my power limit is set to -25% and fans are at 100% again. I get around 70C-75C under load, but i have increased performance.
FurMark Score with 0 power limit - around 74 fps average / fans at 100% 89C (before changing thermal paste)
FurMark Score with -40% power limit - around 49 fps average/ fans at 100% 76C (before changing thermal paste)
FurMark Score with -25% power limit - around 64fps average/ fans at 100% 73C (AFTER changing thermal paste) Default max Core clock 1366Mhz, runs at 830-840mhz with -25% power limit.
I need your help to provide good guides/tutorials for undervolting/underclocking. I have seen some on undervolting, but they don't explain it very well.. some only change stage 7 mv and some say you have to change all stages. I can't seem to find any on underclocking, but i found out, in essence , it's the same as overclocking , but opposite.
For some reason when i opened custom tab for tuner, by default last 3 stages are set to 1150mv, but my 3rd or 4th stage is set to 1156mv. Isn't that weird?
So my goal is to achieve low temps around 65C-75C without having to set "minus" on power limit using undervolting + underclocking if necessary. I don't care if i still have to use fans at 100%, but would be better if i don't. This will be done inside Radeon Software tuner, i don't use MSI afterburner or any other 3rd party sofwatre.
