I just set up my machine:
Cori7 920
HD4850X2 (2G)
6G ram
ASUS P6T mobo
corsair TX650W
here is my problem. I run 3D mark vantage (came with card) and I get the following problems.
the water is going crazy meaning the waves peak so high that the go through the roof and eventually all I see is stretched water all over the scree. Also the FPS is very low. my gpu score is around 4800 I should be getting around 12000 with this card.
CCC detects both GPU's and crossfireX is enabled. I enabled ATI overdrive and both GPUs pass the clocking test. I wanted to monitor the GPU speeds so I opend up 2 sessions of GPUZ to send the sensor data to two seperate log files. then I played the crysis demo for about 10 mins. I closed teh Crysis demo and opened the two logfiles. only one of the GPU's was being used. overdrive increased the clock speed and the GPU usage was at 99% while the other GPU repored 0% usage and 500MHz clock speed.
So I guess what I am wondering is, is this a problem with my gfx card, some ASUS mobo compatability issue, or a driver issue. is there some kind of diagnostic I can run on my card? I dont want to go through the hassle of RMAing my card just to have the replacement perform the same way. Any ideas?
is there any advantage to this card over having two 4850's in crossfire mode? I might just rma this for two of those if they will perform the same as this card.
