GPU render clock stops at 405mhz

[Remo]

Hey guys, I hope you can help me here..

So my two GPUs (980ti) somehow seem to stop at 405mhz clock speed (around 40°C), even in "High Priority" mode.
(Before the holidays it rendered around 1200mhz at its peak)

So im really not sure what happened in the meantime but Id really love to get my render speed back..

Where could I start investigating this issue? What could cause that slow down?

Id appreciate every hint!!

Cheers, Remo

Hi, Remo.

from what I experience so far those kind of drop downs usually happen due to driver crash after too aggressive overclock or so. Have done anything with Your card? (I mean any manual overclocking?).

If You haven't done any OC, try rebooting properly (if You leave computer only to sleep, never turned off) & to reinstall drivers if that would not help. Another thing, try to restore defaults on any OC software You've been using.

Let me know how it goes & I'll try my best to come up with solution for this =)

That sometimes happens to me when I disable my 980TI's and then re-enable them. (I have some weird software that crashes with multiple GPUs, so I sometimes disable them in Device Manager.) In my case it just takes a reboot to get them back up to regular clock speed.
