When you see it drop to 980mhz what is the GPU % load for the card?

Still at the 90's, with offset GPU clocks it does not drop that low only to 1202 in certain scenes on heaven 4.0 and the total score is 2045 but with the modded bios it drops to 1917 due to the crazy GPU clock changes on card 1, card2 rarely reduces the clock.

That's odd, it should be maxxed out with the usage in the 90's. The only time mine ever drops is when my GPU usage is below 50%

Try another program/game that will keep them into the 90's and see if it still drops

I havent tried any other game or benchmark yet but I'll get back to this over on a weekend.

Great guide!
I am very curious though.

With my SLI Gigabyte GTX670 Windforce, without touching my voltage I was only able to get +58 on my Core Clock, but I was able to get +700 on my Memory Clock and successfully pass Heaven 4.0 with my first card hitting 67 degrees + play a round of Battlefield 3. I'm a bit worried, though. Is that too high?

Not really overclocking related but I've noticed at rare occasions in SLI that one of the 2 cards will sometimes run only at about 80% GPU usage but still at full clocks. Say for example with Heaven 4.0 both my cards are usually maxed out even from the very start of the benchmark but there are rare cases one of the cards get pegged at 80% tops. rebooting solves the issue though. I wonder whats causing this and how to prevent this..

I was doing this for my evga 670 and I was able to start off with the initial settings (1100 boost clock, power target and voltage slider are at max) and I was able to pass Heaven with temps 66 and under. But after trying to bench my card for a few hours, I tried those default settings and it failed Heaven in just a few scenes. Now the temps are going over 70 even when i reduce the boost clock to +100. Is this normal? Or did i somehow burn my card out frown.gif Please help!
post #2738 of 3357
what are your guys thoughts on running two different clocks on each card? card 1 for me runs +115 on the core and +77 on mem card 2 runs +75 on the core and +90 on the mem. should i avg the two and run them the same or can i just run different clocks for different cards?

Hi, i've been following this post for a while now and it actually helped me. It has been a while since i've bought my 670 TOP and i decided to test it, see how far my chip would go. After a few hours of testing and benchmarking i think i got to my 670 sweet spot. The max offset, without crashing , i could get was +79 for GPU Clock and +550 for memory clock. I was actually sad, i thought that my TOP could actually get near the 1300mhz GPU clock but it stopped at 1254mhz boost. Any ideas on how could i get better results? I've tested all the tweaks on Uniengine Valley, since Heaven was crashing my drivers. After the benchmark i would play battlefield 3 for like 15-20 minutes to see if the game crashed or if the temperatures would go to critical levels. My max temperature, while playing was 65ºC which i think is good. When it comes to crashing, unfortunately it crashed once on BF3 with a +79 gpu clock offset. Believe it or not, i lowered it to 75, since i think it's the max i could get out off my chip without crashing, for a whole game.
I figured that a TOP graphics card would let me OC more but i was mistaken.
Thank You.
