Afaik 680 makes 46 fps on 1080 p max tesselation aax8 afx16

At least that what i saw in reviews,,,

I had to declock my memory to 7200 - with 7400 3.0 gives artifacts. I guess I will have to bump memory voltage. Anyways... no idea if it's good or bad cause I'm not huge unigine fan still it's the score now with everything maxed out:




I know these were older drivers but with the same settings 680 got 45.3 on average...

But I can't say I'm sure this review is ok

So is it safe to run a gigabyte OC 660ti at 1.212v at load?

Not trying to be smart a** but really no one knows yest as cards are only 9 months old so far . Nvidia lowered the limit to 1.175 . Now lets put this into perspective .
Even at 1.212v that only happens during boost states so basically when gaming .

So question is this, how long do you game a day and how long before you expect to replace/upgrade the card .

If your answer is like 1 hr a day and few yrs then I say , IMO its pretty safe .

Also don't try to run clocks at very max point for 24/7 , find the max on core and mem and then back down a notch or two . especially on mem as that does not boost .

Question, your running 1.212v on load, it does back down , I mean in the bios did you set voltage to 1.180 ? , thats the max i would run and if I expected card to last like 5yrs I would go very little on voltage , like 10-20mv+ max .

This is all my opinion I have to data or facts to prove anything .

Of course she underclocks at idle. Lowest clocks she hits is 324/162/0.987 v. I game no more than hour a day and i probably won"t have my card more then a year. I also have warranty so i actually don"t give a damn if she dies. It"s just, voltage rising makes 50mhz of gpu clock difference and my card runz 6-7C hotter in crysis 3. So i was thinking is it worth it. But basically it is smile.gif

I basically just wanted to ask is there people running these cards on 1.212 for longer periods, like a few months. And having no problems. Also is 72C at max load a good temp?
I have put artick mx4 paste onto her and fans are spinning at max.
I know yours msi 660ti is safe running 1.212 but she has improved voltage regulation. I have a gigabyte OC version and have to mod bios if i wan"T a voltage bump. So i tought maybe there is a reason that software controll isn"T enabled. VRM"s are what"s worrying me, not the gpu. Thiis gigabyte PCB has great electronics so there SHOULD be no problems.

If You get 72 C it's bad temp, because over 69 Your card throttles 13 MHz down.

You should always keep kepler below 69. My Twin Frozr IV gets 55-60 degrees with custom fan profile at max with raised voltage (+50mv) maximum 50% fan speed.

If I put it on 100% it gets lower than 45 degrees.

It is probably fault of Your case.

I have CM HAF 912 Plus 2x120mm intake thermaltake fans (switching them to sickleflow so it will be even better), 1x200mm top fan and 1x120mm back fan

I'm also adding side fan in two days (120mm) - IMO You should think about providing better cooling to Your case. But if You already have it it means that either Your gpu cooler is faulty, or it's just poor cooling solution.

It"s not my cases fault, i have a fractal define r4, 2x 140mm 1000rpm intakes, and 120mm exaust at 1700rpm. It"s full of fresh air. Even if i open it up temps are the same.
Crysis 3 makes very hii load and she runs 7-8C cooler if i don"T overvolt her. So this gigabyte cooler, artick mx4 paste and fans at 100% usually she wont go over 60, 64 in crysis3. Witch is good. I overvolt her and she hits 72.
EDIT: also this gigabyte cooler is one of the best non referent 660ti coolers. And it"s very quiet. I just i don"T think she can go a lot under 70C when overvolted unless you buy an accelero extreme.

You can always get Twin Frozr IV cooler which seems to be much better than Gigabyte considering what temps do I get. wink.gif What is Your ambient temperature?


When I get back home I will check if I don't have wrong temperature readings on my GPU. Will get back to You ASAP.

well i have put her back at 1.212v and max speeds. Ran heaven benchmark all maxed out at 1200p. Card is at 100% load, tdp ot around 105-110% and she didnt se more then 60C.

It"s just, crysis 3. Damn enormus. Once you max it out it"s like furmark. Tdp in some scenes go up to 130-135% and temps catch 70C. My ambient yesterday when i was testing was at least 20C.
I do have an extra scythe kama flow 1900rpm so i mah position it somewhere where it"s gonna cool the gpu. I"ll figure something out. But yeah i"m keeping her at 1.212v.

Anybody knows why my MSI 660 Ti PE/OC throttles itself always after 20 minutes of use? My card is at 58ºC on full load Unigine Heaven/Valley @Extreme HD. After 20/30 minutes of usage (minimal like a game from 2003) the TDP drops from 98.7% to 70% and the performance of the card is 50-60% worse, from 40FPS to 17FPS in any game.

Example GPU-Z log:
