Hi there!

I'm copying my thread straight from reddit (https://www.reddit.com/r/AMDHelp/comments/6ou6fc/asus_rx580t8g_strange_throttling/)


Computer Type: Custom Desktop

GPU: ASUS ROG-STRIX-RX580-T8G-GAMING 8GB GDDR5 @1451MHz core clock, 150% Power Target, 87°C Temp Target via ASUS GPU Tweak II

CPU: Ryzen 1600X with a Thermalright HR-02 Macho Rev. B @stock

Motherboard: ASUS PRIME B-350 PLUS

RAM: 2x 8gb Corsair cmk16gx4m2b3000c15 @2666 MHz

PSU: be quiet STRAIGHT POWER E9 | 480W CM

Operating System & Version: I.E. Windows 10N with all updates

GPU Drivers: Radeon Software Version 17.4.4

Chipset Drivers: shouldn't matter

Background Applications: shouldn't matter

Description of Original Problem: In some games I noticed framedrops from time to time. In Titanfall 2 it got so bad that I had <30fps for like ~1 minute but only a few times a day. So I went back to the monitoring & stability tools -> see Troubleshooting

Troubleshooting: I used GPU Tweak II to read out the clockrates and temps during gaming when the problem occured. The GPU clocked down to 300MHz - temps didn't matter.

Then I wanted to know when the GPU starts throttling, used Furmark and opened up my case to be sure everything has enough fresh air. Here are the results:

no throttling @65°C, 80% fan speed stopped after 10min
throttling @68°C, 60% fan speed after 3:15min
throttling @72°C, 50% fan speed after 2:25min
throttling @76°C, 42% fan speed after 2:05min

The GPU core temp doesn't seem to matter. My guess is that there is something else heating up and throttling but I don't know what.

CPU is out of question because it's cool enough and the RAM modules are also not affected by the GPU airflow. Maybe it's the mainboard? There is a passive cooler right next to the graphics card but this shouldn't happen right? It would be a big design flaw.
