TenthReality: you may be overloading your PSU if you somehow managed to plug the 2 video cards on the same 12V rail as the rest of the system. This Corsair 1000HX is not a single rail 1kW, but has two 12V rails of 480W each. When fully loaded, your system may be over 480W:
151W (5850) + 188W (5870) + 125W (1090T) + ~50W (estimate for rest of the system) = 514W > 480W
However, if you have done your wiring in a standard way, the ATX12V connector for the CPU should be a separate rail. In that case, it is still possible for you to be over 480W if you overclocked the video cards.
Bottom line, check your PSU's manual. Make sure you put the 2 video cards on 2 different rails.

Do you have any software to check actual voltages ?
Sure do, I toe the line on most voltages, but it looks like when everything is running the +12v runs up to 12.05, which is what leads me to think its an overvolt.
12.05 it's normal voltage value.
Looks more like not enough power from PSU. What your PSU power?

1 GPU is connected to the "non-modular" PCIe's that come with it, 1GPU is connected via modular.
Note in another quick test, if I pull card #2 (5870) and CPU mine and GPU mine at the same time with the 5850, I can also make the noise occur.

Howdy All, I've been beating my head over this one for 2 days without luck so I'm tagging you guys in.
Machine in question:
Motherboard: Asus M488TD-V EVO
CPU: x6 1090T
PSU: corsair hx1000
GPU1: 5850
GPU2: 5870 (non crossfire, monitors connected to both)
Case: thermaltake element G (pretty damn high amount of airflow)
The problem:
If mining with GPU1 and I fire up GPU2, immediately I get a loud screech/beep noise that sounds like its coming from the motherboard.
If I fire up GPU2 and not GPU1, no noise.
First thought was thermal issue, so I fired up the usual monitors, and everything appears well inside happy ranges. When that didn't pan out, I played around some more, and found out if I CPU mine while running either GPU, I can get the screech to occur as well.
So, it is not isolated to just the GPU's, it is not a thermal issue, powersupply should be more than enough to cover the setup, what am I missing here. Overvolting the 12v rail because the CPU is a dirty whore?
