GPU keeps underclocking itself

[Zaptecc]

So I have an Nvidia GTS 450. I know it's old, I'm saving up for a new one right now. Anyways, it's been undeclocking itself a lot lately. After a few minutes of intensive load, it just slows waaaaaay down to 50 mhz core clock and 135 mhz memory clock. The temps never reach above 60C, and I'm pretty sure it's not a power issue. The only way I've found to fix it so far is to restart, but it's getting really annoying to finally launch a game just to realize I need to restart.

use DDU uninstaller to do a clean install of nvidia drivers?

I had a similar issue with my 560ti and I solved by doing this but it might not work for you:

Go to Nvidia control panel:

3D Settings -> Manage 3D Settings -> Global Settings -> Power management mode -> Prefer maximum performance

So in theory it shouldn't underclock itself anymore as a power saving feature and keep the clocks up.

try uninstalling and reinstalling the drivers

Awesome, thanks for the feedback. I'll see how this works and if you don't get a response, it probably worked.

This is a pretty fresh install of Windows 10, so I can't imagine it's the drivers.
