Title: Question & Help: (7970, win7 32bit, GUIminer) GPU is running almost 50% of GPU2
Post by: Dalkore on May 24, 2012, 06:56:57 PM
Community.


I built a miner last night and today I am testing it out and I am getting 271 from GPU1  and 541 on GPU2.   Windows 7 32bit, GUIminer, Catalyst 12.4, Afterburner.



What would make GPU1 run so much lower?   Its almost 50%.


Temp on GPU1 - 67

Temp on GPU2 - 43


Note:   GPU1 CPU usage is showing near 94% and GPU2 is between 90-100%


Voltage Settings in Afterburner

Core Voltage - 962
Core Clock - 1000
Memory Clock 710
Memory Voltage 1600



Please let me know where I need to start trouble shooting?  Thanks

You should try cgminer :)

What do I need installed to run it?


Also, are you saying this is the magic bullet?   Can someone please look at those settings and see if any red flags are there?


Thanks Much,
Dalkore

Windows? I just switched over... Easier to use then I thought it would be.

Lower speed and higher temps? That seems a bit odd. Throttling?

I was having the same problems with 5850's in my gaming system.. 1 card would be stuck in 2d mode... I hooked up a TV via hdmi to the second card and ran something high def... it took the card out of 2d mode and worked fine...

I thought that was odd as well.   GPU1 is running at 69 degrees, 91% gpu usage but only 280 mhash?    Is there any setting in Afterburner and Catalyst I need to make sure i have on or off?

Download cgminer 2.4.1 just double click on this blue line. ^^

When using cgminer.. I do not use afterburner or even install the catalyst control center.....


Everything can be done from cgminer :)

So what you are saying is the my miner is the reason for this slow down?    I am going to upgrade to CGminer then.   I am just surprised this piece of software would run one GPU at 50% of another.

I believe the gpu being stuck at 2d clocks is a driver issue.. not a miner issue.. but who knows....

Recommended driver for a 7970?  Should I use the disk it came with?  I went to ATI and got the latest version from them.

UPDATE:

Ok I am now running CGMiner and I think I have the hang of it.   This is what I am seeing on the slow card it is showing:

Engine Clock 500mhz

Memory Clock 150 mhz.

Vddc:  .950

Powertune: 1%

Activity:  53%


Now I see the problem but when I change the values is does update on this GPU.  What would prevent CGminer from changing these values?

I've found that 12.4 has a very peculiar bug with my tri-fire setup. Namely that my 2nd and 3rd GPU both run at 50% (and get half the hashrate)

12.3 resolves the issues for me.

Thank you kindly.  I uninstalled 12.4 and afterburner and just installing 12.4 only.  If that doesnt help then you have given me my next option.   

Please keep the suggestions coming :)  Thank you.

P.S.  Your right, once you CGmine, you never go back.  Command line I love you!!!

Please try to install MSI Afterburner or GPU-Z and monitor your clock frequency. It's possible that one GPU is running at a lower clock frequency.

12.3 worked as in now they are both giving around 550 each, which is around stock.   

Now I am using CGminer and it doesn't seem to implement my gpu changes like lowering the memory clock, lowering the voltage or changing the core clock.  I have 12.3 install and no afterburner.  What would cause this?   Do I need to modify the config file instead of doing through the command line?


Thanks much,
Dal

You install AMD SDK 2.6 right?

No need to install with 12.3. Already comes with newer OpenCL drivers.

I believe the 50% activity has something to do with the card being stuck in 2d mode.... The card get's hot but doesnt run very fast.. I have the same issue with a 5850 at times....

7970 and cgminer don't mix well.  Use Afterburner to change memory and voltages.  When in cgminer, voltage is always stuck; however, it is not really that value.  Use GPU-z or afterburner to see the actual voltage.  Memory likes to "stick" in afterburner, so I set memory in afterburner, then set it to the same in cgminer.

Also:  Close youtube.  Turn off hardware acceleration with flash (rightclick on a youtube video -> settings -> uncheck enable hardware acceleration)  Hardware acceleration sticks the card in 2D mode with 500mhz clock.

This is correct, it comes in the package.  I have 2.6 standalone as well.
