The big thing that I'm wondering is if there is anyone with an sli setup that has just one card that throttles. It happens to me on a fresh os install so its not due to my windows install. I have seen one person with two cards claim that both throttled and I've seen a few people with more than one card claim that it didn't throttle. So that leads me to believe that it still could be a compatibility issue of some sort.


I have two cards in SLI that DO NOT Throttle. When tested individually on Air they did not throttle and on water in SLI they do not throttle. One card does go faster and uses the full 1.200v, while the other maxes out at 1.187v.

As usual, you have your set of clowns that come in to defend the way it's working stating we want 1200-1300mhz which is simply not the case. We just want it to work as it's described in the video and if max oc is 1100 or 1300 then so be it.

Yeah, there were a couple of trolls at Hardforum doing the same thing. That is the video in the words straight from a Nvidia reps mouth that sold me on the card. Thats the way that I had expected my card to work. From every source that I've seen thats the way that it supposed to work.

Anyone kinda wish Titan could just revert to GPU boost 1.0?

That seriously would make things SO MUCH EASIER.....controlling one variable to prevent throttle, whereas with GPU boost 2.0 the entire thing is still a mystery and nearly non-controllable.

Something is not right with that BIOS. I did a CUDA benchmark of my DP code and it ran maybe about 2x slower even though the core clock read 1300MHz... Reflashed back to my original BIOS.

Also, I'm sure some/most of you are aware, but NVIDIA Inspector allows you to put the maximum state as P2 (instead of P0), I got a little bit of improvement on throttling/higher clock speeds that way.
Code:
nvidiaInspector.exe -setPstateLimit:0,2

Where 0 is the index of your GPU -- which should be 0 for most of you, it's 1 for me because I'm driving my display with a GT 640 and using the Titan for compute tasks.

With stock EVGA SC BIOS, NVIDIA Inspector set to P2 state, with P0 and P2 clocks set @ 1176 and memory @ 2504 in NVidia Inspector (my program is not memory bound) I get avg TDP of 105.79% over 146 second run @ average 98% GPU load.

My min/avg/max clocks over this run are: 1032.1/1121.2/1175.8, respectively.

I wish Boost would be abandoned altogether and we could go back to the Fermi days. frown.gif Imagine what beasts our 680's and Titans would be if we could clock them like we did our 580's???

Just saw this on the GeForce forums:

We haven't been able to reproduce this behavior thus far. Is there any other information you all can share that can help us reproduce this problem? I assume you are all using eVGA Precision 4.0? Can anyone send us the VBIOS for your graphics card to driverfeedback@nvidia.com? Any other settings being adjusted in PrecisionX? Thanks for your help.
Please send me a PM if I fail to keep up on replying in any specific thread or leave a driver feedback: Driver Feedback

Looks like MaunelG doesn't see the issues on his side yet frown.gif

He wants more info.... time too blast their email and twitter with all your tests everyone!!!

200 pages of info right here not really reproducing anything as 90% of their cards will probably act strange to(different from what they advertised).

Thats why I pushed the effected users to at least bring up the issue on Nvidia forums.

I agree, I find it hard to believe that myself but then again thats what they said about the vsync issues that I had when they launched GTX 680.

Looks like I just saved a bunch of people here the trouble of having to play the farce ManuelG is attempting to set up.

Even so, go there flood their inboxes with all of our data, cause I guarantee they will say they can't use the information in this thread to help them because it doesn't have all the required data.
