Readings WAY Off in Xfire w/ 2nd or 3rd Card

[Theta]

Here's a problem I'm having with adding a second or third card into this system currently. I have tested with 5850s, 4890s, and 2 5870s. All exhibit this issue. Can not see correct clocks, change clocks, voltage, etc. on 2nd or 3rd card.

Screens taken from a brand new Win7 install on a fresh SSD - using Catalyst 9.10. Motherboard is EVGA X58 TR. Tested as follows:

Card in 1st PCIE slot = OK
Card in 1st PCIE slot, Card in 2nd PCIE slot = Bad readings on 2nd card
Card in 1st PCIE slot, Card in 3rd PCIE slot = Bad readings on 2nd card
Card in 1st PCIE slot, Card in 2nd PCIE slot, Card in 3rd PCIE slot = Bad readings on 2nd and 3rd card

Is this a motherboard issue / failure or something else? Does not seem driver or hardware related, after switching cards, driver sets, etc.

Anyone else seen this?

Its a problem with the GPUZ software, not with your hardware.

When I overclock and overvolt using MSI afterburner, the overclocks are detected in CCC, and the voltage increase definately works as the cards are stable at the higher clocks, but GPUZ still only displays the default clocks, same thing if I overclock in CCC.

So I have found that voltage and clock changes are working on both my cards, but are not detected by GPUZ.

Unfortunately, it shows these clocks in CCC, as well. No overclocking software installed on this box (fresh), no Overdrive.
