Default What's up with one of my GPUs?

One of my gpu's is only pulling in 2800ppd. Is there something wrong with it?

The good news is the other one is running at 6500ppd.

I see you folding on a cpu. Stop that one for a bit and see what happens.

What cpu client are you using?

It's the Windows SMP client (MPICH version).

Is the slider at 100% GPU usage?

You try stopping that client and see what happens to your gpu client?

Where is the slider? I only see the slider for CPU usage.

And Chris, I installed the gpu client first and it had the same ppd before I installed the cpu client.

Can you download GPU-Z and check if your shaders are running regular speed?

Under Configure>advanced tab make sure the slider is all the way to the right. It says CPU but it means GPU.

Actually, it does mean CPU. That slider controls the amount of CPU time the client will allot to the core, since even GPU folding requires CPU time in order to operate. It should still be set to 100% since otherwise the client might end up starved for resources.

Yes, the slider is set to 100%. Here are the GPU-Zs, I've even overclocked the shaders as you can see.

Can you expand out the GPU-Z screenshot a little more so we can see the specific work unit? Some WUs result in different PPD.
If the "slow" GPU is folding a 511 point work unit while the other one is folding a 384 pointer, there's your answer.

Either way, your slow GPU is folding faster than my Radeon 4870

Even with the ACBP projects, an 8800GTS should do more than 4k PPD.

It is definitely an odd situation, given that before loading up WinSMP, the clients did not have to fight for cycles. A couple things to check though:
- Under the Advanced tab in your client config, are both clients set to "Slightly higher" core priority? They should be.
- Try checking "Do NOT lock cores to specific CPU" and using a program like PriFinitty 2 by Ed Wilk to make sure both GPU clients have access to both cores.

I don't know what happened but XP did a couple of updates and restarted my computer. When I started up the clients, they both run at around 6500ppd now. Thanks for the all the help, don't really know how it got fixed, but am glad it is.
