Club3D Radeon HD 7850 royalQueen

While testing the card I have noticed the power consumption in idle was abnormal.
I decided to check what was going on so I started to check with GPU-Z if the card was going to the lowest power state like it should.

ASUS:
As you can see the memory clock isn't going down as it should from 1200 MHz to 150 MHz.
Since this is not a driver issue as it works fine with the ASUS card and since the ASUS card makes use of the same PCB/Power Design (but different memory ICs, Elpida => Hynix) we recon this issue to be caused on a BIOS level.
I also monitored different voltages on the cards and here are the results:
ASUS:
vGPU: 0.82v
vMem: 1.57v
vPLL: 0.85v
Club3D:
vGPU:
0,9vvMem: 1.57v
vPLL:
1.05vWe have already contacted the manufacturer and waiting news from them. On our side we will try to flash the card with another BIOS see if that solves the issue.
