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?)

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)

Maybe I should try a different miner? Highly doubt that'll work either though..

Try 12.2 with SDK 2.5. I always used 2.5 on my 5970s with no issues.

I'm all for switching to CGMiner, but this sounds more like a kernel issue.

As far as I can tell 2.5 isn't available for WinXP. 2.3 seems to be the newest version for XP.

Oh man, I am full of fail advice today.

You shouldnt get more than 340 mhash on a 5970 core @ 725 MHz, even with perfect ram speeds and miner/kernel options. If you're spiking 350-370, definately something awry going on there. Is your GPU activity maintaining 99+%? Doing nothing on the computer running on the miner? I'm running 5830, 5870, 5870, 5970, and 5970 and I get sudden dips of GPU activity (40-70%) if I do ANYTHING on it, and it kind of cascades between the 7 GPU's for about 30 seconds before stabilizing and getting back to 99.5+%

My GPU's maintain about 60-75% activity. And yes, its a dedicated mining-server at the momemt, so I'm not doing anything else on it.
Tried only running one core again and then the activity goes up to around 96-98%. Strange..

What driver/SDK? Back with the old 100% bug if I ran both my cards on the same CPU, their hash rates would suffer.

As I wrote in the main post, 11.10 and SDK 2.1. When it comes to the CPU it maintains about a 50% load.

Ah I see that now. Must have glossed right over it. Tongue

Like ssateneth said, 50% of a dual core CPU is 100% on one core, and if you run both instances of Phoenix on the same core, the hash rates suffer. Upgrading to 11.12 will fix your problem.

You shouldnt even get that much load either. I get 1% CPU on a 7 GPU rig, single core 2GHz. I'm going to bet you have a dual core CPU. You still have CPU bug. 11.12 and 12.1 don't exhibit the CPU bug with 2.1 SDK. Unfortunately, I tried 2.5 SDK a little while back on 11.12 and I had CPU bug. Will take some futzing around to get a 2.5 SDK combo working..

Then I'm gonna give 11.12 and/or 12.1 with SDK 2.1 a try. Thanks for the tip. And yes, I do have in fact have a dual core CPU(C2D).

I have a Radeon 5970 in my server that I'm using for mining, but I'm having some issues with it. At first I had problems getting both cores to work, but I seem to have fixed that now. The problem now though is that the hash rate is fluctuating a lot between about 170-350Mhash/s on each core. Shouldn't it be more stable than that? When I try mining with only one core its a lot more stable and stays at around 340-350Mhash/s.
The GPU's are at stock-speed(725MHz) and I haven't done any clocking other than underclocking the memory to 500MHz(wont go lower than that in either CCC or MSI Afterburner).
Should also mention that I'm using WinXP 32bit, Catalyst 11.10 and Stream SDK 2.1. And I'm using GUIminer with phoenix to mine.

Also, I'm currently using these flags:

-k phatk VECTORS BFI_INT FASTLOOP=FALSE AGGRESSION=7 worksize=128

For some strange reason I get the highest hash rate when I set AGGRESSION to 7, any other number and hash rate drops.

Anyone have any idea of what could be the problem?

i get the highest hash rate at 6 and 7 aggression too, but i don't believe it, so I use 9 instead

it shouldn't fluctuate that much though. @ 6 or 7 i might see jumps from 360 to 390 or something like that. did you try checking temps? it could be throttling itself

Check you powersupply.

But what you are explaining sound more like a temperature problem. Use GPUZ to check what your VRM's temps are... Make sure they dont go over 90c and you should see "throttling" stop.

I don't think my power supply is the problem. Its a 650W 80+ gold FSP power supply which should be more than sufficient.
And I have checked all temps with GPU-Z and nothing is above 90C.
