GPU-Z doesn't report right GPU load.

_A.T.Omix_ · Feb 19, 2013

Hello,

I noticed while mining that GPU-Z doesn't report the accurate GPU load, but something like 5% instead of 98%'according to AMD System Monitor.

Please post a screenshot and list your system specifications.

Thank you.

Thanks for the screenshots!
However, what exact model of AMD HD 7900 series videocard do you have?

_A.T.Omix_ · Feb 20, 2013

Gigabyte's HD 7970

Looks normal to me. :confused:

In the GPU-Z screenshot that was provided, GPU-Z shows the load as 1% - hardly normal when folding or mining. :confused:

Strangely enough GPU-Z doesn't report right GPU load for bitcoin mining but right GPU load when I view a video for instance.

Naki · Feb 20, 2013

Hmm, how about using the GPU-Z built-in Render Test tool - ? mark near the Bus Interface field, does that register correctly (shows as 99% Load on my Nvidia GeForce GTX 670 card)?
Please try other benchmark/stress tools, such as FurMark, MSI Kombustor, 3DMark (any of the latest versions), Unigine Heaven, Folding@Home - does GPU-Z report GPU Load correctly with those running?
Did you try an older AMD video driver version?

EDIT: Also, please double check with other tools - what do MSI Afterburner and EVGA Precision say - do they show the 99% on the left, 1% on the right, or some other percentage?

_A.T.Omix_ · Feb 20, 2013

Right GPU load is reported under 3DMark 2013, GPU-Z's Render Test tool, Unigine Heaven 4.0 and Valley 1.0.
I did not try with older drivers yet (I'm on latest AMD beta drivers).
http://www.evga.com/precision/ seems to target Geforces only.

Naki · Feb 20, 2013

If EVGA Precison won't work on AMD, please try MSI Afterburner then.
EDIT: Maybe it works with AMD too, but without the overclock!
It says it works here:

_A.T.Omix_ · Feb 20, 2013

The results:

You can see EVGA precision monitoring GPU usage in the traybar.

Naki · Feb 21, 2013

OK, since you get 99% in four different apps, it seems you most probably found a bug in GPU-Z.
Please let's wait for W1zzard to comment on this.

EDIT: Please could you also do a test with GPU Shark?

Thanks!

W1zzard · Feb 21, 2013

i'll try to replicate next week

Aquinus · Feb 21, 2013

Does this only happen when your crunching or does it happen when you play a game as well? Does GPU-Z always report GPU usage wrong regardless of the application being used or only sometimes?

_A.T.Omix_ · Feb 21, 2013

It only happens while mining, while gaming or watching a video GPU-Z reports the right values.

AlienIsGOD · Feb 21, 2013

I can verify that while crunching both GPU Z and Trixx report 0% load.

Aquinus · Feb 21, 2013

It appears to be okay on my 6870s when crunching. Maybe it's a 7000-series specific bug?

Please can you also try Folding@Home, if possible?

What exactly are your AMD videocards crunching/munching/chewing?

Same question to AlienIsGOD. Also, AlienIsGOD, what card do you have, is it the same one as the OP?

Thanks!

Never heard of WCG before, seems nice.
I am doing folding, using the official Folding client:

Athlonite · Mar 4, 2013

@ Naki I can confirm that it also reports wrongly whilst folding

CCC = 89%
GPUz = 0~1%
AIDA = 89%

F@H client version 7.3.6

I do know there is an known issue with AMDs new openCL and core_16 on HD7xxx cards but this should not effect correct reporting of GPU load
