Underclocking app for GTX 260M?

I'm looking for any app that allows massive underclocks, the only tools that is still maintained that works on my card that I found, MSI Afterburner, only allows to underclock the VGA to much higher levels then it's already underclocked when PowerMizer is on and the laptop is idle.
If there is any app that allows me to control the clock based on the powermizer clocks that would also work, as I only have a problem about PowerMizer deciding to max out the clock when playing any simple video that should be playable with the lows clock it sets when I'm just browsing.

 

bump
Anyone?

 

I just use nvidia performance tools to underclock mine, the lowest I can go is 125/312/215/ Currently idling at 54 C

 

Weird, the minimum clock allowed here is 151/378, probably because I've set the default clock higher than you did on the bios of the card itself. The minimum clock for the memory if significantly higher than on PowerMizer though, 257 vs. 119 , but due to the apparent lack of options I'm happy with the results, thanks

If you are using the version you posted, I've found out that there are new ones, this is the last
NVIDIA DRIVERS 6.06

 

When i had my G51VX, I never had issues with MS Update drivers downclocking on their own, when browsing usually they maintain at 2d clocks, no need for any extra software, now if you want to go lower than 120/200, then probably check Tevs Guide and flash your gpu to your desired clocks, i would advise against cause your playing with the base gpu clocks, so there a chance of bricking it and no video while booting, you might have to blind flash it. But its worth a read as he also lowers the voltages and you might find what he used usefull for what you want to via software.

I would advise to try out MS Update drives first, This are the last that i tried that work good for me NVIDIA Geforce/Ion/Quadro 198.05 WHQL Drivers , and see from there if they do mantain 2d clocks on your browsing, newer official drives never worked for me.

Just worth mentioning that new stuff in the web will more and more start using gpu acelerated, for example flash 10.1 even new IE9 suppose to. In my case when videos like youtube play on, my clocks go into the second settings (throttle) weather or not this clocks are needed for watching videos on flash idk, but if you leave the web open the clocks will remain at those setting even if its not playing. if you want you can flash your clocks to whatever your want with tevs guide.

 

My problem is actually being with the lack of manual control over Powermizer, not when it downclocks, as it's always right when it does that, but when it clocks to default, it does that even when I simply go to the overclock tab on everest, while no other program is open, then after a few seconds it underclocks again.
Now I found out that even with those clocks I mentioned Powermizer consumes much less power because it's the only way the GPU will undervolt, so what I did is set powermizer back on and set the underclock so when Powermizer tries to go to the stock clock it will actually set those low clocks, but with the default voltage. It helps consume less power than before when it did set the default clock, but it still consumes more power than if I was simply able to lock powermizer to the lowest state.

 

I just updated my driver to 198.05. So far no DPC latency spike. I have tried 186.82 and 197.45 before, but PowerMizer caused audio clicks, pops etc... just like some people describe in this thread.

I'll keep my fingers crossed. Thanks Abula!

 

UPDATE: I have been checking the clock speed with using GPU-Z for a while. 198.05 downclocks more gradually (500 > 383 > 275 > 200) than 186.82 and 197.45 did (500 > 200). Nice!

It's so nice to see my 260 is idling @ 47C.

 

Ill try to rederect Forge here, i always avoided using 3rd party programs and prefered the way MS Update drivers handle the downclocking, but he did try other drivers than MS Update and he did use powermizer and flashed the GPU multiple times and i believe he even used lower clocks than the 2d/idle clocks, he might be able to help you more than me.

NP, hope they work good for you, those were the best i found, but i also sold mine a month ago, didnt try newer drivers.

In most of the recent nvidia gpus there are 4 clock settings, 2d/idle, throttle, 3d and Extra. Different clocks for different scenarios, in theory it should also change depending on the load, for example in WOW when i was under light sceneries, the game will downclock to 3d and sometimes to throttle, but what i didnt like is it not always return to Extra settings even when there were heavy action going, not sure how it really suppose to work, the behavior doesnt change any different with not downclocking drivers, you just have the higher clocks but the utilization of the GPU isnt full, so its just more power consumption and more heat but no more performance, this is just how nvidia does their drivers/hardware, in games like MW2 you cant see this behavior, so i really didnt care much at end, the games still played fine. There is a lot of talk recently about % of gpu utilization never going up at Guru3d, and seems nvidia is trying to fixs this.

This will fix your problem for sure... it underclocked and undervolted my card..

 

My primary clocks for my GTX 285M's idle level are 150/300/90 @ 0.7V.

 

Thanks again for the great info!

198.05 has been working great so far. I played MW2 and worked great! The highest temp I got was 86C. I still want to put some copper blocks (I have repasted the GPU heatsink so far), but I'm happy with the result. I used to get over 90C.

 

I have been summoned by Abula. However, I'm not understanding the problem. Is it that you don't want the GPU to downclock, or the downclock isn't to your satisfaction, or what?

 

I want to be able to lock the GPU to the lowest Powermizer state, only clocking to default again when manually requested, but I don't know if that's possible anyway.
When I downclock it manually and turn off powermizer it doesn't undervolt as I explained in one post, if I could somehow control the voltage manually that would work too.

 

What are your ambient temps like, the heat in my apartment is on and I can't control it

 

The only way I could think of--other than maybe a crazy registry tweak, which I know nothing about--would be to set all other clocks in vBIOS to the lowest level, and use something like EVGA Afterburner or RivaTuner to clock up or down at command.

 

You do know the other states like video are at higher clocks for a reason right?

 

What do you mean by all other, all other states other than the 3D clock? Playing videos here still activate that. And if I just reduce all clocks leaving the last state with maximum voltage that would leave me where I am right now...
It should be possible to make a software that controls the voltage manually, since Powermizer does it, I guess the lack of one is just because no one with the knowledge decided to take the time to make one yet, if there was one I could just set the clock to minimum using nvidia system tools and set the voltage to minimum, and when necessary clock it to the default voltage and clock.

Yes, but considering that youtube(or similar) videos plays without any problems with the lowest clocks I can't see any reason I should allow it to go to the highest clock just to burn out the battery...

 

It's about 68F w/heat on.

 

But that might not be the only app that uses the throttle/3d settings, like for example games do go down depending on the load, it might be fine for flash 10.1 but might be unstable on a game that goes down to the same clocks settings due to load. I think its good how nvidia did it, there are 4 settings for different scenarios trying to hold all the different things a user can do, if you go to specific you will need thousands of gpu clock settings, and this imo not viable, specially since not all cards are the same.

A lot of things in PC are standardize to allow safe margins for most and a lot scenarios. Things change over time, when the card was released there was no flash 10.1, but other things come into play in each of the Clock settings, generalizing into one small part might make other apps not be stable, and while tweaking is good you have to take a lot of things into account. Regardless of trying to min/max the GPU voltage n Clocks, the biggest battery drawing should be the screen, the cards already have decent clock settings, maybe not super tweaked for each individual card, but work for most fine. I think you would get a better impact if you just find lowest clock/voltages on each setting and flash the gpu with those.

In Flash 10.1 apps, on start it should go to Extra on start (i think) and then downclock depending on the load, most of the time it goes down to throttle, not saying it cant be played at 2d clock settings, but i think the difference shouldn't affect to much regardless.
