Is it possible to downclock my video card to save heat/energy?

post #1 of 5
Thread Starter 
I run my PC 24/7 folding. I rarely use it for gaming anymore. I keep it in the basement and have all of the fans on full blast including the GPU fan. It usually keeps a temp of 38C while down here.

Is there any way I can downclock the 8800GTS (G92) from the stock settings to use less power and produce less heat?

Rivatuner lets you go below the stock settings, but it seems like such a silly thing to do that I am afraid to try it because I don't know if it will damage anything.

Why on earth would putting less load on the video card damage it? Think this through....

38c isn't bad at all, my 8800gts idles at 48c however i have it overclocked with the fan at 100%

downclocking cannot damage anything

if you don't use the card for gaming you should lower the fan speed so it isn't so loud

I wouldn't think it would damage it, but I have never heard of anyone doing this so I was unsure as to what its repercussions may be.

The PC is in my basement so the fans do not bother anyone. I just wanted to see if I could put even less power and less heat into the case.

You can underclock to conserve energy, but just keep in mind, that like overclocking, there are only certain speeds that the card will function properly at (that includes sub-stock speeds too). I don't know what those are. To be honest, I don't know how much of an effect it'll really have. 'Cause if you're not running a 3d app, your computer is running in 2d mode, which is an underclock of the 3d clocks, and I'd be surprised that lowering the 2d clocks more than they are will really have that much of a effect on the overall power consumption. If you want to lower power consumption of the system, use fewer fans/fans on low (assuming that your CPU won't get too warm).

Also, having the GPU's fan running 100% when not in 3d applications is a useless waste, and will likely result in nothing more than shortening the lifespan of the fan.
