Updating this thread again. Just tried to reformat the drive and did a fresh WinXP-install and the first thing I did was to install Catalyst 12.1(with the included SDK) and nothing else.
Then I started GUIminer and set it up just like before, and guess what? THE F***ING PROBLEM STILL REMAINS -_-.

What the hell could be the problem? Could one of the cores on the card be broken? Or could the problem lie with the pool rather than my computer? Or could it be some strange setting that I'm unaware of?

Might try installing Ubuntu instead and see if I can get it to work there.. If not I think I'm gonna sell the 5970 and get a good singlecore-card instead..

use phoenix

and get windows7

I'm starting to consider installning Ubuntu on the server instead and see if I can get it working properly there.. Anyone else running Ubuntu with a 5970?(or any other dual-GPU card for that matter?)

Look ARROUND!

Sorry, I didn't mean to hijack, I just thought I was having an identical issue. My apologies.... I will begin a new thread once I have GPUz up with more info. Thanks for the understanding.

I think i'm experiencing temperature throttling on one of my GPU's myself. Either temp, or power.. Should be hashing around 415M or so, and it starts out at 415, but after 1-3 minutes, it throttles down to ~260M hashrate. How can I tell if it's the temp or the power doing it? What tools do you recommend?

At 725MHz, you won't be getting 415MH/s, you'll probably be getting more around 320MH/s.

Again, open up the task manager and look at your CPU core usage. Turn down the aggression one at a time until your CPU usage isn't pegged to 100%. What's your hash rate at that point?

Evanesce is not the one experiencing 100% CPU. He's experiencing throttling. Really he should start his own thread instead of highjacking JayPhizzt's, or use the search button, what what can you do? Roll Eyes

get gpu-z and watch the sensors tab

if the vddc current red bar shows lines or gaps it's throttling.

Watch the VRM temperatures ( all of vddc phase #X temp ). The core temp is insignificant, as the VRM will overheat long before the cores do.

the VRM need to be below 125C to prevent a throttle. If you see temps above ~110c it's likely throttling before you see the temp spike. Best bet it to keep the vrm below 100C

Use GPU-Z to monitor both the temps and the power. Be mindful of the VRM temps, as well.

Not sure if this helps,
But I use SDK 2.1, and drivers 11.12 with 3 5970s and 1 5870 in a rig. (7 GPUs) I have not gotten any errors at all, or YET.

Make sure you don't install the actual SDK EXE installation, but extract it with WinRAR and only install the SDK MSI file. That got my hash rate up a bit.

Ah, ok, I shall do it this way instead then. Which .msi-file is it exactly? SDK_dev?

I extracted "ATIStreamSDK_dev.msi" from "ati-stream-sdk-v2.1-vista-win7-64.exe" using WinRAR, installed it, saw my hash rate improve.

If you have WinRAR just right click and choose extract to. Make sure all old drivers, SDK and other stuff have all been completely removed.

Also if you can, just reformat. Or completely remove your drivers, and install 11.12 first.

I've tried this now and my problem still remains... I also tried installing 2.1 in a different folder and it didn't help.

I think I'm gonna give up on this now since nothing I do seems to work. When Win8 comes out I'll be getting a new computer with it, then I'll probably install Win7 on the server instead and then I'll see if I can make it work on both cores. In the meantime I'll just have to settle with one core..

I remember back when this affected me, I had 2 instances of phoenix running, one for each card, and then I set the CPU affinity (or taskset) to different cores. On the cores I put my miners on, I changed the governor to powersave, to no run more power than I had to.

This was in Linux (Gentoo), and I have an Athlon II X3 (tri core). I had it set like this:

Core 1 | Core 2 | Core 3
ondemand | powersave | powersave
3.1GHz | 800MHZ | 800MHz
No miner | GPU 1 | GPU 2
0% | 100% | 100%

This got me full hashrates with the 100% CPU bug, but didn't run my CPU at 100% for an extra ~80W.

When I got my 3rd card, it looked like this:

Core 1 | Core 2 | Core 3
powersave | powersave | powersave
800MHz | 800MHZ | 800MHz
GPU1 | GPU 2 | GPU 3
100% | 100% | 100%

Uninstall whatever sdk you have. Do a search for opencl.dll and delete them all. Then Reinstall.

I uninstalled the drivers then deleted the one opencl.dll I could find and then I installed 12.1 with the included SDK.
Now as soon as I start mining on the second core the entire system freezes..

Drop your aggression down. I have setups where 9 will jump to 100% on a core, but 8 is fine. I even have one where 9 is fine on all the GPUs, except the one driving the display which needs to be 8 or lower otherwise a core gets pegged.

Just use 12.1. It's the last ocl driver for xp. Sdk 2.1 or use the one with 12.1. CPU bug should be gone.

I have tried 12.1 and it doesn't help.. It doesn't seem to matter what drivers and SDK I use, both the CPU-bug and fluctuating hash rate remain.. And I've tried many different drivers and SDK's now..

Does anyone have any other idea of what could be causing my problems?

yeah, 12.1 should be fine.

i have 3 5870's in a system w/ phoenix & aggression rating 9, it's about 1-2% per instance (this based on my dual core e6850 that's been underclocked to like 1600mhz and 1 core disabled)
