Need some help figuring out my 7950 crossfire installation

post #1 of 9
Thread Starter 
I'm guessing that it's likely a Windows based problem, but I recently purchased a pair of Gigabyte Windforce3 7950s from Melee, and while I know that both cards work after Windows acknowledging them as operating properly in Device manager and doing at least one WU each in F@H, I've thus far been unable to get any video output from either of them, installed individually or in Crossfire, when plugged into the primary PCIe slot...My rig and configurations are below... any help and suggestions are greatly appreciated as I will be unable to do anything after tomorrow in order to resolve this issue due to my plans to be out of town Friday through Sunday... and with the FFW starting up Sunday at midnight, I would really like to have this problem solved before then. Thanks in advance to all those who help me out in figuring this out!

CPU: FX-8120 - currently at stock defaults
MB: Gigabyte 990FXA-UD5, F12 bios
RAM: G.Skill Ripjaws X DDR3-1600 16GB, 4x4GB (9-9-9-24-33-2T)
GPUs: Sapphire Vapor-X Radeon 5870 (finally going to be retired once I resolve this frustrating issue), 2-Gigabyte Windforce3 Radeon 7950s (both with F43 bios and stock bios)
PSU: Lepa G900 80+ Gold 900W
CPU Cooler: Corsair H80
ODD: Lite-On 12x Litescribe BR-Burner
HDD: WD Caviar black 1TB (current boot) and 1.5TB (former boot, recently wiped and reformatted in lieu of worst case scenario being a fresh Windows 7 install)
OS: Windows 7 Pro 64-bit
Case: AZZA Hurrican 2000

What other troubleshooting have you done...if any??? Is your CPU/GPU overclocked. What drivers???

My CPU and GPUs are all at stock clocks until this whole situation gets resolved. The GPUs have the F43 bios and the stock BIOS (dual bios is such a nice new feature over my 5870, once I actually get them fully running) but unfortunately neither seems to be working for the display problem I'm having. Unfortunately I don't have a DVI cable or I'd try that, because hell, we all know that hardware can be finicky about the darnedest of things sometimes.

I tried uninstalling CCC and doing a registry wipe and fresh Catalyst install (BSOD each time I tried uninstalling Catalyst, which I only tried due to a simple update not fixing things) and thus far I have had no success with Catalyst 12.2, 12.4, 13.2, 13.4 or 13.9 beta... which are all the versions I've had. I've run chkdisk and did a system restore back to several older configurations, none of which worked. I ran Memtest86+ and have gotten no errors through 10+ passes so I know my memory is okay, and the HDDs have shown no problems. I flashed the MB from F11 to F12 after the first few unsuccessful attempts and now I still don't get the display output, but at least F@H will recognize the 7950s and both have run through at least 1 WU on the F43 bios with no issue. I've sent Gigabyte tech support 3 emails this week and 2 help tickets for each card with no response... at this point, the lone thing I can think of is it's something Windows related, so much to my chagrin,

It's seeming like a fresh install on the recently reformatted and tested 1.5 TB HDD might be my fastest fix... short of having to reinstall my full Steam library frown.gif That's honestly the biggest reason I'm trying one last ditch effort that someone can think of something I haven't... The only upshot of doing that is if I have do the fresh install and it works, I'll just leave Steam open in the background with F@H and download my library while I'm gone this weekend, lol.

That is a thought, but if you look at "The Machine" in my sig, you'll see the direction I'm heading... for the time being, I may or may not Crossfire the 7950s... I'm kind of liking the idea of running one as a full time folder and using the other for all my needs while I go through the 6-10 month process of upgrading to the monster level build I've been wanting for so long. Considering how big I want to go, I can make due with the 8120 for another 6-8 months smile.gif

ok but I WOULD CHECK if XFX and Powercolor card still unlocks after having Aftermarket cooling.(they unlock to R9 290X)

Honestly, I think I would be plenty happy saving $300 dollars to put towards the custom water loops and just overclocking the 290s to a point where they can match the 290Xs at stock/light OC. Let's be honest here, they are cards meant to and successfully competitive with the GTX 780s... for $100 less per card. I don't really have a justification for going beyond the $400 price point for GPUs unless I get a raise/better job and I decide to go apeschnitt on the build like Fat Italian Stallion's Project Liquid Death, lol. It'd be asweome, but I think that a total investment of around $7,000-$8,000 is all I want to put into this upcoming build.

Bear in mind of course that includes price tag includes the water cooling loops and a trio of 27" ASUS PB278Q 1440p panels for a 7560 x 1440 array of freaking sweet. smile.gif

I know what you meant, I've read up a lot on that thread, but honestly, it seems like a crap shoot as to whether or not one will get cards capable of doing such... it seems to be a specific block of cards made and likely a manufacturers errors in putting the 290x chips on cards that were made to be 290s. Also, given the troubles I've heard of a great many people having had with XFX GPUs, if I went this route in the hopes of getting lucky, it would definitely be with the PowerColor cards if at all. I have plenty of time left to make that decision, so that's a bridge to cross at a later date, right now I'm more focused on getting these 7950s running properly, lol.
