I ve manage my psu server 2000w to do 12.5-.6 V.
In power hashing - 12.25-.30 V.
600- 4.7-4.75 TH
Its better from before.

OK well that simplifies things. 
So the board with the < 12V was that measured using the same connector cables as the other measurements? if so then that board must be taking quite a bit more current than the others? Is the temperature higher on that board?
I think still worth fully powering the miner and then measuring voltages on the 3 board connectors.

Question bradli?
When the miner is fully plugged up what is your PSU configuration? Is it a single PSU or multiple? If multiple what are you driving with each supply?
Definitely you have a low reading on one board, was that measured when powered from the same PSU wiring as the other measurements? Tha is to say is it a PSU / wiring problem or is that board taking more current?
As well as individually powering boards & making measurements it would be good to fully power up the miner, set it hashing and then make 3 measurements directly into the board sockets as you have shown?

Singel Psu. I think it s board. When the miner is fully plugged up what is your PSU configuration? Is it a single PSU or multiple? If multiple what are you driving with each supply?

Is that measurement of 12.08V made with the S7 Hashing, and what about the other 2 Hash Boards, they do not seem to be powered?
Rich
Yes. Without hashing its show 12.26 VRich
2 of boards with Hasrate

I think that last board has some problem

So I see 9 single headed cables that go into your s-7 from the miner.
to get proper voltage you need to measure at the plugs attached to the miner which means probes into the top of the pcie jack. risky to do but possible to do.
I will photo. in the morning
I'm not sure what you mean by using the top of the PCI-e jack, meanwhile using the PCI-e connector should be safe?;to get proper voltage you need to measure at the plugs attached to the miner which means probes into the top of the pcie jack. risky to do but possible to do.
I will photo. in the morning
The way i do it is just stick the pointy probes in the back of the PCI-e connector, where the wires goes in. I suppose you need some long/pointy enough probes but that should let you check the voltage that goes into the miner without risking shorting some pins.
yes that can work I was going to photo it for him.
I have not seen his voltages for his machine.
no one has shown me a correctly measured s-7 with all jack/pcie at 11.9 that does not work after a softboot.

please look at these photos :here is a single cable head if this is how your cables are and you have 9 plugged into the 3 boards how can you or how did you measure your voltage?
so if the fix I give does not work what are your load voltages on all 9 jacks?
this is a two head pcie cable one is loose one is plugged into the board if you measure the empty end you get a true full load measurement which is 11.96 in my case

there is something going on that is not quite right.
sometimes it just tosses errors at the 0.1100 rate and hash drops off say 4500 vs 4800.
in my case I can do it with hard power down and then power up. needing a soft boot to fix it.
my psu is solid 1600 evga p2 using 240 volts on a socket 2 feet away from the main box.
I do 11.94 volts after the power draw 12.07 before the power draw.
try to see if your cables drop to 11.80 or less.

some of cables is 11.8-11.9
the most of time i cant get more 4.5
i used IBM 2000 W server psu
I ve tried a few times reboot and nothing
same and pick up errors
always wait an hour or two to see if it is doing well
If you can't get 4800 solid at freq 600
try to clocks at :
593.75 it should do 8x or 4750
587.50 should do 4700
581.25 should do 4650
575.00 should do 4600
See which number is best.
Maybe you can do 593.75 and get 4750
yeah I see. it seems when the hw rates shows .1100 or more the scores are terrible. this is just what mine did.
can go to system reboot do the reboot via software and see if you get hw rate like .0100 to .0500
after do the reboot wait 10 minutes then check the hw rate if it is under .05 it should get better and better if it is .1100 it did not take. if it di not take drop to freq 581 try that.
