one gpu core on 5970 won't downclock

hi all, i've got this annoying issue with my 5970; the primary gpu sits at 157/400 in 2d mode, but the other gpu sits at 735 constantly, with the only time it drops is during loading screens in games and when i open gpu-z, selecting that core from the drop down menu at the bottom.

any idea what's causing this?

cheers
 
have you tried reinstalling the latest drivers?

The second GPU should be at 0 / 0 Mhz with the latest drivers.
 
If using msi afterburner, there is a bug in it that reports the second gpu at full speed.

you sure? it clocks up and down depending on gpu-z being open/loading screens in games, which suggests to me that AB is working fine. also, the temps show that that core is hotter, ergo it is at the higher clock speed...

not if you've disabled ULPS. i get ultra-mega-BSOD's if i have it on :(
 
My 2nd GPU on my 5970 sits at 000mhz/000mhz - your saying this is right? How am i supposed to know if both cores are working properly?

And what is ULPS?

yes, that's fine for it to run like that.

mine causes BSOD's galore if i have ULPS enabled, but the 2nd gpu should downclock to 157 non-eyefinity or 400 eyefinity, it simply doesn't do that when it's supposed to

yes im sure, hers a quote from the version history that states there is a bug with the second gpu, msi blame ati though lol.



•Added AccessibilityCheckingPeriod configuration file switch for improving the compatibility with AMD ULPS power saving technology on Crossfire systems. The switch allows low-level monitoring module to use AMD driver API to check GPU accessibility and detect and display GPU sleep state properly. Please take a note that AMD API implementation is ineffective and hardly suits to realtime monitoring due to high CPU stress resulting in periodic stuttering in games.
That is why the compatibility switch is disabled by default, enable it only if you absolutely need to see slave GPU sleep state on the graphs and accept side effects like performance drop and stuttering resulting from ineffective AMD API implementation

cheers.

so is that saying there is an issue with ulps AND crossfire, or ulps and crossfire separately?

is this what ULPS is? how do you check to see if this is enabled or disabled?

do you not have google?

ULPS puts your card in an Ultra Low Power State (the hint is in the acronym)

this means it either turns off the card or puts it on very low clocks and thus using a teeny amount of power, as they are not needed to do 2d stuff.

gpu-z will tell you if it is on or not
 
Yes i have got google though forums are generally a place for discussions anyway....

I have GPU-Z though am not sure where im looking for that, though im guessing if CCC shows the 2nd GPU as being 000mhz/000mhz thats the ULPS? Have you just made a profile for your 2d clocks have you managed to disable ULPS a different way?

open up gpu-z. look for it saying ULPS. you can't miss it.

clocks being 000 do indeed mean ULPS is active
 
Well i cant see it in GPU-Z, im using version 0.4.0 and knowhere does it say re ULPS.

I just wondered how you disabled it rather than having to make a custom 2d profile which is what most seem to do. This is the first time ive seen a thread saying about disabling a power saving feature instead of making a custom profile
 
google disabling ULPS

i can't be bothered to do it for you.

why am i helping you in a thread i asked for help in?!

start your own thread if you want advice :D
 
I wasnt trying to take over your thread lol

I can tell you how to make a custom 2d profile where you can set the cores, though im guessing if youve used google youll know how to do this too :D
