I observed the same issue and the only glaring commonality between our setups is the motherboard which is Asus Z270A and Win10. No idea what is causing it so far...
In my case the drop in performance on GPU0 comes and goes. Meaning it resolves itself randomly while mining and then comes back again in a few minutes. Seen it on 1080's, 1070's and 1060's.
Will watch out for it on a new H110 Pro BTC under Linux later today.

Topic: Claymore - GPU0 always reporting lower (all setups) (Read 693 times)
try if you can use the onboard GPU for the regular video output, then all your 1070s will perform full without loss on 1st card 
if bios complains, look if you have somewhere "Windows 10" enabled, disable this and just enable Bios itself to UEFI only - thats enough for running (just during installation i'd to enable always Win10 and remove all GPU's, then disable Win10 and add all GPU's and leave the onboard GPU as primary video output)

All my systems are 7x or 8x GPUs - I'm not sure if the asus Z270-A will allow you to keep the onboard GPU running with that without causing another issue?
with additional 7x GPU's it should work, not sure about additional 8x GPU's - i have 6x GPU rigs not to take any risk on the PSU
Ok so I've tested the risers idea, that didn't work (Also did it with the GPU directly in the motherboard).
FYI: All the system use team view to remotely log in and check the setups.
This has already been done
I'll try this now, however if I reapply the same OC manually (although no numbers change) GPU0 works at full speed.

It's because GPU0 is the one that also has to do the work for the display.
Go to system properties->Performance->Select "Adjust for best performance".
Remove any background photos.
Reduce the display resolution.
Close any other programs that may be using the GPU.

I have the same. 6x1070 setups. I did notice the the clock get limted on gpu0. I noticed that if I open chrome and leave it open it goes away

Its a headless machines setup.
However, my risers are a mix of version 6,7,888.
I will try change the main PCI slot to Ver 6 to see if that helps.
I assume its nothing to do with the gen 1 or 2 settings in the bios?

your riser is v7 ?
Just change your riser. use v6 riser.
This is for only the maimn pci e slot.
The problem will be solved.

Could it possibly be the GPU you've got the monitor/dummy plugged into? It will take a little bit of processing power to handle the display task.
Hi All,
I've got a strange issue. GPU0 are always reporting less hash than every other card when using claymore 9.6 - Eth only (on any pool).
This is happening across all my rigs (10x) so its not specifically related to this card. If I move that card's riser to another PCI port it works fine, but anything plugged into the the PCI port which related to GPU0 has this problem.
Note the when the PC is restarted the issue appears to resolve itself but will return after hashing for 10-15 minutes.
Even if I return the cards to stock memory, it will always report lower as well.
Can anyone shed any light on this?
