I replaced my MSI R5450-MD1G with an ASUS EAH5770 CuCore ($99 after Christmas special ). Uninstalled ATI drivers prior to switching cards then rebooted. Windows installed ATI driver 10.7.x and I installed ATI CCC 10.12. Almost immediately, my system froze and I had to do a hard shut down. Rebooted again and was able to run non-3d applications. However, attempts to start WoW and SC2 crashed the ATI drivers or froze the entire system.
Uninstalled CCC 10.12 and reattempted with 10.11, 10.9, and 10.8. I even uninstalled Afterburner when this failed and tried the most current Asus software, which made things worse.
Next attempt was to also delete the hardware in Device Manager and move the card from primary (lower) PCI-Ex16 slot to secondary (upper) PCI-Ex8 slot (a very tight fit with the internal case fan). Windows auto-installed ATI driver 10.7.x and I installed Afterburner when it seemed stable. Upgraded to 10.8 (driver only) and the system is semi-stable. Random driver crashes in both Windows desktop and 3D games (WoW and SC2), but it seems to recover. I repeated the process using 10.9 with same results at fewer instances.
I suggest you drop both your CPU and memory back to stock speeds and see what happens. If the system stabilzes at stock speeds, attempt to re-install 10.12.
How are your temps running (get hwmonitor, the free version, if you don't know)?
Also, is the PSU new? Not clear in your system description.
Last, nice mobo. The "primary" PCI-E slot is the one closest to the CPU itself, not the other one.
I will test out CPU/RAM stock speeds later in the week.
According to Afterburner, video card temps usually run 50-70C (winter ambient temp. in the room around 60-68F) when I play WoW or SC2. Unfortunately, I cannot run Asus AI Suite since adding the new video card. It crashes the ATI driver or freezes the system. Not even a BSOD.
PSU: Antec TruePower New, 750W --> enough power even if I X-Fired 2 cards and added three more hard drives.
Regarding the MB, the lower blue PCI-E slot runs at x16 with a VGA switch card installed in the upper PCI-E slot. Asus recommends single card setups to use the lower slot. Otherwise, both slots run at x8. Referenced from the manual, page "2-20".
Update on problem:
Previous Graphics: MSI R5450-MD1G – OC’d to 700MHz core, 890MHz memory; hybrid X-fire w/ MB’s HD4290 IGP; ATI CCC 10.11; MSI Afterburner 2.0
Current Graphics: Asus EAH5770 CuCore – Factory clocked at 850 MHz core, 1200MHz memory; ATI 10.11 drivers only, MSI Afterburner 2.0
Reattempted ATI driver (CCC2 v10.12, CCC v10.11, driver only v10.11/.10/.09) installation with the CPU and system RAM at stock speeds. BOSD with CCC2 10.12, more freezing with 10.10/.11, and semi-stable at 10.09, but still no improvement.
Steps taken were:
0) Uninstall MSI After Burner 2.0
1) Uninstall using ATI uninstaller in Control Panel - Programs and Features
2) Reboot to Safe Mode
3) Clean using Driver Sweeper 2.7.5
4) Reboot normally
5) Install ATI drivers or CCC package and reboot
6) Start and attempt play 15-30 minutes of SC2 and WoW.
7) If very unstable, repeat from step 1.
Reinstalled MSI Afterburner 2.0 when the system was semi-stable. Checked for any Microsoft updates and found a driver package dated October 2010. It installed ATI driver version 10.11 (according to Afterburner). Seems very stable now, but still had 2-4 driver failure/recoveries yesterday.
