GPU Under Clocking

mgrape1337 · May 5, 2017

My GPU is clocked at ~1000MHz while gaming and I usually overclock it to ~1200MHZ. After playing Rocket League while overclocked, it began to lag which I then checked on Afterburner to see what was the problem. My GPU peaked at ~800MHz and sometimes even went down to ~400MHz making most of my games somewhat unplayable. I really have no idea what happened and would like to know if any of you could help me?

Sounds like thermal throttling. What did the temperatures look like when you started to notice the clock speed reduce?

GPUs will automatically lower their clock speed to keep within the thermal (and power) parameters assigned.

Barty1884 :

The temperature of my card was at around 70-75°C when at 1200MHz and now it is at 55°C max even under a load.

Check your overclocks.
When Nvidia's driver detects an error it will downclock the card. Another error will downclock it more.
The only fix is an OS reboot.
Check your overclocks with OCCT or Furmark with error checking enabled.
