I can only think of a few more things that I do, that may or may not help. Make sure crossfire is turned off, disable ULPS in afterburner or in the REG. Check the core clocks, and make sure they are not throttling. Are all your Mobos the same? Check gpuz and see if they are not stuck in pci-e 1 mode. If you are using risers, maybe try swapping them. I am reaching, but i know how frustrating it is to troubleshoot. Cry

Well after thinking about what Vorksholk said I realized since the GPU's are the same the WU's should be fine even if I move cards in the middle of work so I swapped the cards between two machines.  Ironically, the cards that were running at half speed now run at full speed and the cards that where running at full speed are now running at half speed.  Clearly the issue isn't with the GPU's.

So I suspected it had to be the PCI settings on the motherboard but GPU-Z shows both machines are set to PCI-E 3.  Crossfire is off on those machines, ULPS is disabled and the clock speeds seem to stay at 940 which is where I have them set.  The GPU's are placed directly on the motherboards so there are no risers.

I really have no idea what else it can be at this point.  I'm wondering if I have a bad motherboard.  All the motherboards are the same as well.  Actually every component is identical in the computers.



Can you post a log with some complete WU's ? What's your GPU utilization like ?
Cosmetically I have the same thing with some of my rigs - only giving 50% of expected PPD and nothing helps. But the GPU's are working away at ~95% utilization so it seems to be a glitch in the F@H software.

I saw your messages about it before as well when I was having the same issue.  I actually rebuilt two computers from the same image at that time.  One runs at "full" speed and the other "half" speed based on the PPD estimates.  This was the case before the rebuild and again after.  The GPU utilization shows 100% in GPU-Z on both machines.  However, the estimated PPD is half on the machine in question.  I don't have logs to show the actual points right now because I've been messing with the machine so much today.  I'll have a log in 12 hours from the machine that appears to be acting odd.

I do hope it is just cosmetic but don't you find that odd?  I mean one machine has a cosmetic glitch even after a wipe and a GPU swap?  That just doesn't sound likely since it is always the same machine.  For me it is one machine out of nine.  Not all 9 of the machines are identical but 6 are exactly identical and a 7th is pretty close.  It is one of the 6 identical machines that shows half expected PPD.

I watched the timing and it seemed to take much longer to do work on that machine but I know that doesn't necessary mean anything because there is so much difference in WU.  I need to see how many points are awarded after it actually submits the work in the log.  I'll do that as soon as I can.  I don't have any awarded points in the logs for that machine at the moment so I can't post them.
