Firstly...so without realizing that I have a motherboard that only supports second GPU at x4, I still got myself an Asus HD 5850 DirectCU TOP. My first card is HIS HD 5850 iCooler V. Both individually are working fine. I listened to opinions here and decided to go with identical families of GPU to crossfire.
I put them in crossfire mode with Asus as primary, and HIS as secondary. And no matter what I try, GPU-Z shows GPU 2 as Crossfire : Disabled. Using MSI Afterburner, I matched HIS's clocks with Asus's (I did not touch any voltages). I am running official Catalyst 11.3 and I have enabled that checkbox for crossfire in Catalyst control center. But GPU identifier shows just a big number 1. The diagnostic window in Catalyst for crossfire setup is blank.
Just for the record, my monitor is connected to the primary card's DVI-D output (ASUS) since I don't have capability to use that HDMI output.
Why is this not working or seems to be not working?
Secondly - I read many opinions bashing X16/x4 crossfire setup, and many said it is definitely some improvement if not as good as x8/x8 or x16/x8 or x16/x16. What's your opinion? My system is LGA1156 based. If it is really that hurtful, should I save up for a better motherboard (which one?)
Thank You.
