Crossfire BSOD

[hehawkiller]

Hello everyone. I recently inherited a second ATI HD4850 to put along side my other one. Ever since I have started using this second card I have been getting nothing but bsod's. I have tried single card configuration with both cards and both run like they should. I also figured I had bad RAM, so changed those out as well...and still bsod. I did a fresh install of windows as well thinking driver problems and wth...might as well do a fresh one. Still same thing. The only thing i can come up with is my MB is dying...it's a DFI LP DK 790FX M2Rs with the 600SB. Here is the report on the bsod's.

Without looking at the dump it really sounds like your ati driver is confused.
I would completely remove it using this in safe mode
Phyxion.net - Driver Sweeper

Then reinstall the latest driver for the device.

I did a fresh install of windows 7 just the other day...so there should be no driver conflicts...unless the ATI driver itself is bugged with older cards. I am very confused since i never had a problem untill installing this second card. Am I possibly missing something in my bios??? I've done everything that i should have, I leave all settings in CCC at default, and I'm not overclocking, in fact i'm underclocking my HIS card since it's stock values are 650/1000 and most 4850's came at 625/993, so i had to underclock to match speeds. I will give what you said a try..and i'll keep my fingers crossed!!

driver problems are usually started at the point of install.
Meaning something didn't go right when you originally set it up.
Time frame actually fits pretty well.
At any rate the process can't hurt anything.

...and the clock tweaks could even be causing the driver issue.

So upon mearly reading your last post...i get another BSOD with the same report as above. I have done what you suggested, and i'm still recieving this error...i'm going nuts about this...I think i'll go back to a single card for now, untill I get a new system. Thank you for trying to help. If you come across anything else, or remember anything...please let me know, I would love to resolve this.

Well bios updates for your motherboard come to mind.

I had a old DFI LP board. It died when the fan they stuck to the bridge burned out.

I do notice there have been a lot of bios updates for that motherboard.

Have the latest bios...lol...i've tried everything. Like I said i think i just need a new computer. I might possibly have damaged something on the board when i used to overclock my X2 5000BE, i was mean to that CPU...lol!

well heat, dust, and static are the three big killers of computers.
If you rule out water though I don't see many people pouring water on their computers.
It's possible you have just burned up some components.
I think I would do a fresh install before just condemning a whole machine though.
Even if you are getting a new one, you can keep this one for a media server to your tv or something.

Did you ever get a chance to look at the dump files? I still have BSOD's everyday, sometimes more then once. I've made sure i have all the correct drivers, have a fresh install of the o/s, and still problems...i have since resorted back to single card configuration.
