Two ATI Radeon HD 4870 X2 used in Crossfire.
Overclock settings are at the default. I haven't messed with them.
AMD Catalyst Driver Version, and Driver History
Presently using 12.4. Was using 13.4 until today.
When I first purchased the system with these cards, I could run games like Civilization 5 and Skyrim on high using crossfire.
A year or two ago, crossfire started causing textures to flicker, so I had to disable it for most 3D games.
Starting this year, any full-screen 3D games will now flicker every minute or so, accompanied by graphical lag. I'm hoping to find a way to restore the original performance of my cards. I was using 13.4, as the support site says this is the most recent for my cards. Upon reading through some release notes, however, I found 12.4 to be the last to support 4800 series cards. I completely uninstalled 13.4 and all application profiles before installing 12.4. The flickering still occurs, though crossfire seems to work better now. Less texture flickering. Just lag flickering.
Motherboard or System Make & Model
ASUS M3A32-MVP DELUXE
It's not in my purchase invoice from five years ago, and I don't really want to open up my computer to check right now.
Display Device(s) and Connection(s) Used
Applications and Games
Diablo 3, Skyrim, Civ5, probably others that I can't recall right now.
AMD Athlon(tm) 7750 Dual-Core Processor
Not overclocking it unless the computer shipped that way.
Motherboard BIOS Version
Pretty sure, at least. I don't believe I've updated it since I received it.
System Memory Type & Amount
I don't know the brand. Four sticks of 1GB DDR 2 memory. 802 MHz.
Nothing of consequence, as far as I know.
Did a virus scan with Microsoft Security Essentials. Checked Speccy for anything appearing out of place. Didn't notice anything. Fiddled with the VISION control center settings a bunch.
