Solved Sapphire 7950 running as a 1GB card instead of a 3GB card? Tags: Graphics Cards CPUs Graphics Last response: October 7, 2012 11:22 AM in Graphics & Displays Share BennyF August 26, 2012 10:36:18 AM Ok, I'm having some major issues with my new system, mainly the Graphics cards. In CPU-Z and games they are showing as 2 1GB cards rather then 2 3GB cards. They are showing as 3GB cards in the Catalyst though :S System: MOBO: ASRock X79 Extreme9 CPU: Core i7 3930k (stock speeds) PSU: Corsair AX1200 Ram: G.Skill Ripjaws Z 16GB (4x4GB) 2133 GPU: 2 Sapphire Radeon 7950 3GB OC Crossfired. They are showing as 1GB cards in 3DMark, CPU-Z and all of my games, what's going on D: PCMark11 results on Extreme test. http://www.3dmark.com/3dm11/4221239 More about : sapphire 7950 running 1gb card 3gb card bryonhowley a b U Graphics card a b à CPUs August 26, 2012 11:00:22 AM I would check them one at a time. It looks like you might have a defective card. If one of them is only showing 1gig that is all you will be able to use in Crossfire. BennyF August 26, 2012 11:23:53 AM Checking this right now, also I forgot to mention, Catalyst shows them both as 3GB cards, but basically nothing else does. Also 1 card in testing atm is showing 1024MB i'll be back with the second card in a second Related resources Overclocking the Sapphire Radeon HD 7950 3GB - Forum Radeon HD 7950 3GB not much better than my Radeon HD 6850 1GB ? - Forum AMD Radeon 7950 3GB - Forum Gtx 660ti(2gb) vs Radeon HD 7950 3gb - Forum Sapphire hd 7950 Vapor X vs Galaxy gtx 660 Ti 3gb - Forum Can't find your answer ?

(Dirt3, GTA4 and Shift2 all do it so far) BennyF September 5, 2012 9:55:36 AM Best answer selected by BennyF.
