Lock GPU clock rate to max

post #1 of 17
Thread Starter 
Hello,

I need to know if it's possible to lock my GPU clock to whatever it's set to, so it doesn't throttle down whenever it thinks the load is low.

I have a problem in some games where the driver seems to think the load on the card is low enough, so it lowers the clock rate to lower power consumption.

Is there an easy way of doing this?
Please don't bother telling me why it is doing this and why it is good, as that's the only thing I've been reading about on other forums all day.

Thanks.

You should be able to use MSI Afterburner and lock in your OC:http://event.msi.com/vga/afterburner/

MSI Afterburner does the same thing as ATI Overdrive, it increases the maximum clock. It just has the possibility of exceeding the limits that ATI Overdrive sets. This doesn't disable the down-throttling on "idle".

Vsync is disabled in everything. When this problem happens, I will have 45 max FPS with constant drops in games like Heroes of Newerth and Bloodline Champions; games that I had no problem running earlier on, and should be able to run at at least 121 FPS if I wanted to.

I need to somehow disable this down-throttling when my driver thinks it's idling.

I really need to know if there is a way to lock my clockrate or disable down-throttling.
I made GPU-Z log my GPU and it jumps up and down constantly when I'm in-game.

Either make a custom overdrive profile in CCC, then edit the clocks of lower power states, or edit the BIOS directly and do the same.

First option is easier and safer. Give me a few mins to try and find some tutorial how to do it.

Thank you very much, Tomalak. I haven't been able to find out how you set the profiles in CCC. I have the newest version.

I'm not that experienced, so editing the GPU BIOS is not something I know much about.

Ok, see here:

http://forums.amd.com/game/messageview.cfm?catid=260&threadid=100048


Its for the older CCC, not sure if its different in new ones.

EDIT: Ricaz, I'm really not sure about new CCC, or even if its still possible. I'm at work now, can check when I get home.

Well, I tried doing the trick in the post you just linked - by editing the profiles.xml file there, but that somehow only changes the overclock values in CCC. It still throttles it down to like 157MHz on "idle".

I can't find this profile thing inside CCC (although editing the profiles.xml changes SOMETHING), though, so it has probably been removed. But I'd like to know more about flashing the BIOS so it will let it run at max speed no matter the load.
