Moboard: Asus p6t-2e
psu: corsair 1000w hx
cpu: I7 920 Stock 2.8 ghz,
ram: 12gb, 2gbx6dimms (at 1333)
OS: win 7 home 64 bit
2x Asus Matrix 5870 2gb,
1x Stock (from original dell) 5870 1gb
So basicaly i recently put in the new mother board got that working well enough. Then put in the Two new Asus matrix cards, and it will load into windows hang once it gets to the desktop then i get a BSOD saying it's Dumping the physical memory. if i disable the cards in safe mode then it works.
On a side note every time i install the drivers, (i've tried the ones Asus recomends, and the newest from AMD) I get a warning say "error messages occurred during instalation" I view the log file and it doesn't say what went wrong. So i've tried to delete the old Drivers as well as i possibly can, including using CCcleaner to clean the Regs, and Driver sweeper to clean everything else out. I've updated the Bios and drivers for everything i can think of.
Ok well, i took out the 1gb Card, and it booted just fine, Including running two of my three monitors. I feel like i should be able to Crossfire That extra card. they're both 5870's Obviously the clock and memory are different, but i was under the impression that Those would synch up. Though i suppose that would only give me 3gb of video memory as opposed to 4gb with the two cards. So maybe i'm better off with only the two?
I bought them from Craigslist a guy who lives close to me (vancouver, canada), he has a large Pile of them actually.
The one recommendation we always gave you guys is to keep it simple at 2 GPUs maximum, as after 2 GPUs in a CrossfireX setup you quickly run into weird anomalies that can be irritating......So over the years Multi-GPU support has improved quite a bit, AMD still isn't up-to snuff at the level of NVIDIA though, multi-GPU supports still literally and directly remains the Achilles heel of ATI's Catalyst drivers......So let's round things up, personally we always say stick to one or maybe two high-end cards as there is so much less driver fuzz to worry about. It's like this with ATI, once you pass 2 GPUs you'll often find yourself compromising a lot with new game titles versus multi-GPU support.
Before the 68xx series, even 2 way CF was sometimes a challenge.
