ATI 6870 not overclocking (Low FPS)

Driftit · #1 03-31-2011, 02:04 AM

Have been having major issues with Low FPS in game. 10-20fps max.

All settings on medium. No AA. Epi Filter off. Could not figure it out.

Until I noticed my card was not stepping up to its stock clock of 900mhz. It stays stepped down at 300mhz.

I have no idea why it is doing this. I checked with other games and they are fine. They all step the card up.

This could be why so many people are getting Low FPS on powerful machines.

I can't confirm my cards not stepping up.

I run 2 x 285gtx with win7 64bit and Q6600 cpu with 8gig ram.

My system chokes on this game yet I can run ARMA2 on maxed out settings and that is way more demanding on CPU then COD.

Some guy posted his conf.ini settings and I am going to try them tonight.

maybe try yourself and back up your old one.

This goes in your documents user folder no where steam has installed.

just change the .txt to .ini let me know if it helps at all.

I will give that a try. I also play Arma 2 and that was the other game I used to test if my card was stepping up. It does so fine.

It sounds like your cards are also not stepping up.

In the ATI tray bar on the bottom right , if you right click it and go to 3D settings you can force maximum clock speeds.

It's a pain but a work around until they hopefully fix it.

4870X2 here and same issue.

Thanks for the info. But I don't seem to have this option which is a pain. Will figure it out.

You have CCC installed don't you?

Is it running in the tool bar?

If so, right click it and select ati radeon than 3d settings and force maximum clocks.

look at my sig to see my system specs...i am running everything at MAX in this 4x4 battle...mind you it is mostly over water and when i flew over the city at treetop level (not in vid) it dropped to 11-15 fps

but it should give you a good reference point

BTW i joined a DF server tonight and was getting 80-120 fps at low to medium settings

it was ugly as hell but fluid

I can confirm this as an issue. I noticed immediately that performance on my crossfired 6950's was abysmal, even on medium settings, and that even with the Epilepsy filter disabled, the secondary card does not throttle up at all (i.e. Crossfire is completely non functional) while the primary card also runs at only 500MHz (instead of the usual 800MHz).

If you want to check your own cards, use GPUz from TechPowerUp. Just run it in the background, with the Sensors tab selected (make sure to tick the box for continuing to refresh the screen while it's running in the background) and then alt tab out to see what speeds it's been running at. Ignore the current speed though, that will generally drop when you alt tab, instead mouse over the red bar for the GPU Core Clock and the value it displays will be the one it was running at. If you have a second monitor though, naturally you can keep the window visible in that while you play.

I have a heavily overclocked i7 930, a pair of 2GB 6950's and 6GB of RAM, yet the game runs more poorly than Crysis did on my old Core 2 Duo/8800GT. Something is very wrong here.

S!

Noticed same on my 6970HD. Core clocks do not go to full, but to 500MHz instead of 880MHz. Memory clocks go to 1375MHz as should. Also noted better image quality with AF overridden with CCC, some artifacts went away with this. I use latest 11.3 WHQL drivers.

I don't have a maximum clocks, and I'm not sure how to tell if its stepping up or down.
I have a pair of 4850's in crossfire, but they are not both working in this game, the splash logo comes on in other games but not this one.

I did go into CCC and allowed the auto tune to OC it.

If you can explain I'll check what you ask.
