Hi all,
So first my specs:
Mobo: GA-MA790GP-DS4H latest Bios (F5).
CPU: AMD Phenom 9950 Black Edition - stock freq.
GPU 1: ASUS EAH4870 DK/HTDI/512MD5
GPU 1: ASUS EAH4870 DK/HTDI/512MD5 (the same).
DDRAM2 6GB Corssair
OS: Windows 7 64bit
PSU 700W
Problem: I have purchased second 4870 yesterday and plugged it into my rig. Win7 recognised it and soon CrossFire worked. But when I started testing it in games it turned out that my case(4 year old) was having big problems dissipating the heat the two graphic cards were making so I bought a new case. Moved everything into the new case except the TV adapter I was not using anyway and booted up the PC. At first it didn't worked and after a few tries I decided to reset bios. Done and now the computer was booting into Win7. I must say I was too tired to make a fresh install so it's the same Windows.
The problem only appeared now as the second card is not showing up in device manager or CCC. I have the latest 9.9 drivers and CCC. Tried reinstalling the drivers after I uninstall and clean with driver sweeper but no luck.I put one card into main slot and tested it and then the other and they both work fine. I am at a loss as to what should I do next. So mainly second card is not appearing in windows device manager or CCC/GPU-z.
