Found it quite interesting... if only we didn't have the 84C limit![]()

Using Rivatuner, I believe you can prevent the 84C limit from kicking in by having the program auto clock the GPU back to normal when it detects the clockrate dropping.

are you serious? wouldn't everyone be doing that if that was the case? i just got my 1647 today but i will definitely be looking into that!

I've done it, I get 90C when benchmarking Resident Evil 5 at highest settings, and that's at 675/800. That's the highest it went though, and it lasted for all of about 5 seconds before it dropped back. It generally stayed right around 85-87...that was with stock thermal paste and no cooling pad sitting on a carpet at room temperature...so I'm assuming that it would go down once I use Arctic 5 and a cooling pad (oh tomorrows going to be an experiment for me with this LOL)
My 3dMark went up by about 2500 points as well from 6220 to 7776. So I was happy to hear about that. Like I said, I just turn it off when I'm done, and Power Play sets it back to 220, and my temp drops back to 50-55 for a bit, then back to 47-48 when it idles. -

I OC'd it by 1 Mhz to 676.
I did finally hit the threshold to shut it down though while playing Empire Total War. So I don't know if I'll do that again. I wonder if underclocking it will keep it steady and override that 84C thing. -
If you want to test the gpu more test it in vantage.
3dmark is a test of gpu and processors combo -
I think you are right because there is a section where it tests CPU, I thought Vantage was a pay to play thing, so I didn't try it there.

I decided to get Rivatuner this morning but I've never used it before. I got it to recognize my GPU but I don't see an option that would combat the thermal throttling limit...or am I looking in the wrong place?

Link doesnt work..

Whoops, that was in the thread that I started a bit ago. I just checked it and it worked.
Anyone doing this with their sxps 16xx? With 4670?
