How to force 3D GPU clocks

[wabbitseason]

Having a bit of trouble with my mobile GPU (GTX 285M) using 2D clocks in games. It isn't a thermal issue.

I know there must be some sort of tool out there that allows the user to force the GPU to run at a particular clock. Ideally I could just toggle this functionality on and off as needed. Is Rivatuner the ticket, or is there another program I should be looking at? Does anyone have a link to a tutorial that actually describes how to do this? (All the rivatuner tutorials I've found are not helpful.)

Try MSI Afterburner.

Though if you're having real trouble with it you ought to check out everything else first.

Make sure you have the lastest BIOS for your laptop as they usually contain the video BIOS as well.

Make sure your nvidia drivers are up to date.

Consider using driversweeper to make sure old driver remnants are causing issues.

I've used a tool like that (EVGA precision) before. It completely fails to lock the clocks at where I want them. Even if I set the clocks to a certain value (stock 3D clocks), the card stays at 2D clocks. I need some sort of forceware, and I definitely remember seeing some folks talk about something like that around here a while ago.

you can do it with msi afterburner.. precision, afterburner, rivatuner are all the same application. they just use different UI's. though afterburner has more options with setting up 2D/3D profiles but not the same amount of options as rivatuner which hasn't been updated in a long time.

if afterburner doesn't work then the dynamic clocking is at the bios level on the discrete card and isn't controllable without modifying the bios.

the cards specifically designed to sit at 2D clocks unless a 3D application triggers it to switch to 3D clocks. unless its effecting gaming performance(which would mean there's a temp issue) there shouldn't be any reason to mess with it.

Thus why I suggested he look at curing whatever issue he has rather than brute force this.

I appreciate the advice but my computer doesn't have any issues, thermal, driver, or hardware related. It simply won't clock at 3D clocks all the times that I want it to (for example when playing older games).

I prefer not to let something other than me dictate what my GPU is doing.

Unfortunately you guys seem to be saying that afterburner/precision/rivatuner are one and the same and that none of them can actually do what I want. Can anyone else confirm or refute?

In this day and age you'll find the standard behavior of modern CPU's and GPU's is to downclock when idling or under low stress. What older games are you playing that performance isnt acceptable on but clocks arent ramping up?

 

[wabbitseason]

I'm aware of the standard behavior. I simply wish to alter that behavior to suit my needs (ex: overclockers turning off EIST, turbo-mode, etc). Everyone on this forum knows that drivers and hardware don't always perform how we expect them; that's why, as power users, we strive to exert maximum control over our hardware.

Nobody else here has this philosophy when it comes to GPUs? There must be some of you out there who have wanted to do this--and succeeded.
