6990 - 6970 x2 Quadfire issue. Help needed.

post #1 of 4
Thread Starter 
So I recently installed my other 6970 to run quad fire with my 6990 and my other 6970 (6990/6970/6970 CFX). Only problem is CCC and Afterburner and what looks like every game/app EXCEPT GPU-Z Says I'm only running trifire, or rather only utilizes 3 cards. GPU-Z Reports 4 GPU's in quadfire. But when I launch a game I only see 3 GPU's being utilized in afterburner. The 4th doesnt even show up in the overlay. although it does show up in the monitoring window.

Catalyst gives me some weird option about choosing my cfx setup. "Your system has more then 2 graphics processors that are capable of AMD CFX. Select the GPU Combo you want to use." Then it gives me either 2 GPU (20 14) (guessing this is my 6970's) or 3 GPU's (20 14 2) (guessing this is my 6990/6970). 3 GPU's is what I currently have selected out of the 2 choices.

From what I understand this type of quad fire should be possible as It was with the 5xxx series afaik. The way its setup is 6990 Is in PCI-E Lane 1 while the 6970's are in 2 and 3. The bridge goes 6990 - 6970 - 6970. All cards are bridged together. The motherboard reports my PCI-e Lanes as x8/x4/x4. I'm guessing because my 6990 counts as 2 cards and is sharing the primary lane as x16, it shows it as x8 because its splitting it for both GPU's? Or have I randomly lost 4 lanes?

Can anyone help me with these questions? Im running 13.2 beta 6 I think. I will upgrading to the 13.3 later today though.

You only have 16 lanes, when you have 1 card you have a x16 link, 2 cards x8,x8, 3 cards x8, x4, x4 - the motherboard says it supports tri-fire, my guess is that the motherboard cannot support the information needed for quad-fire (or the 6990 cannot support it)

How odd for some reason I always thought there was 20 lanes, 16 total for the primary and secondary pci-e and a dedicated x4 slot. rolleyes.gif. As for quadfire I had assumed it was the same as the extreme in being able to support quadfire. The extreme board does not say it supports quadfire or even tri fire, just cfx which the formula also says. Everywhere I read they are the exact same board in performance just some different bells and whistles. hmmm...

*EDIT*** So after some research I found this off the asus website here. https://www.asus.com/ROG/MAXIMUS_V_FORMULA/

SLI/CrossFire On-Demand

Why choose when you can have both?
SLI or CrossFireX? Fret no longer because with the ROG Maximus V Formula Series, you’ll be able to run both multi-GPU setups. The board features SLI/CrossFire on Demand technology, supporting up to Quad-GPU SLI or Quad-GPU CrossFireX configuration. Whichever path you take, you can be assured of jaw-dropping graphics at a level previously unseen.
