Sometimes my gpu runs at lower TDP

[patosaiex]

Hello,

Recently I've been having trouble with my gpu apparently not drawing enough power.

I'm using a GTX 680, and most of the time it works fine.

But every now and then I have a massive fps drop, and checking on gpu-z and MSI afterburner, when it happens the card is running at 26% tdp tops.

Restarting the computer fixes it.

Running furmark 1080 benchmark it goes as far as 115% TDP, and though I can't recall the score it was in line with GTX680 scores.

Also, on rainbow six siege, I get that problem, like, at the start of a round, it goes down to 20ish % TDP, alt tab out and back in and it works fine.

Is it a PSU, GPU or MB problem?

Hello... 1) Check your OS "Power settings" PCI express, CPU, etc for 100% min/max performance setting.
Control Panel\All Control Panel Items\Power Options\Edit Plan Settings-Change advanced power settings.
2) utube "core parking" and diable it in your OS registry.

Sounds like a driver problem, more than anything. Have you updated drivers recently? Some of the newer drivers don't work very well with the older Keppler cards.

Hum... using latest certified nvidia driver.

May want to try to roll back to a version that you know was working. It's the easiest thing to test and try...if that doesn't fix it, then you obviously have something else wrong. Try that first, though. I would bet that it's the culprit.

Hello... I concur... Try some vintage Drivers... 337.88 or 347.88 were some my favorites.
