thermal throttling.. or?

[BillyBerzerk]

I got this GTX 550 Ti my little brother is using (I passed it on to him lol) and while I'm testing the card in furmark it throttles the core clock to like 400MHz I'm assuming this is due to heat. but this happens around 76°C (Max for this GPU: 100°C). strange? I think so.

 

Or am I really just pushing the card too far?

 

1055MHz core / 1230MHz mem

1.150V

stock cooler; without dustcover (4k rpm ballbearing fan on what looks like a 'meh' heatsync)

 

I'm thinking it is my thermal paste.. I'm using some generic gold-looking-glop from coolermaster.

is it that or is it furmark? should I stick to using 3dmark?

 

edit:

I probably shouldn't push this card anymore.. but lets blow it up. why not lol.

Revert it back to default settings, and run the tests again and see if it throttles.

the way to test for thermal throttling, what i do, is go play a game and if its smooth and randomly starts to lag, there ya go

[BloodWithIce]

Benchmarks have more intensive and less intensive parts, so I guess that't normal

Replace that thermal crap and see how it goes.

I did. It didn't. as a matter of fact, it's only doing it once I go above 1225MHz mem clock. So at its current speed (1230mhz) if I run the test for 5 mins it hits 76°C and before it hits 77° it underclocks.

I'll have to wait for newegg to ship me some artic silver 5 (like 3 days)

Does it automatically jump down or do you notice a gradual degradation of you clock speed?

auto-jump. straight to 405MHz exactly lol.

auto-jump. straight to 405MHz exactly lol.

Have you tried reinstalling the driver?

i used to have a 560 ti and this happened to me. then i got a 290 before bothering to fix it lol

yes. I'm pretty much done with it. I think I'm pushing it too far tbh. I up'd the clock to 1060MHz / 1235Mhz and ran Kingdoms of Amalur for about 10mins before drivers crashed. welp, I got a lot out of it. it's enough for him to play minecraft with shaders so he's happy. (and Im happy cuz I get the peasanty out of him haha)
