SAPPHIRE Radeon HD 2600XT 256MB in Crossfire

My System
• Intel Core 2 Duo E6550 Conroe 2.33GHz LGA 775 65W Dual-Core Processor
• DFI INFINITY P965-S LGA 775 Intel P965 Express ATX Intel Motherboard
• 2x SAPPHIRE 100220L Radeon HD 2600XT 256MB 128-bit GDDR4 PCI Express x16 HDCP Ready CrossFire Supported Video Card (for crossfire setup).
• Kingston HyperX 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model KHX6400D2LLK2/2GR
• Antec True Power Trio TP3-650 ATX12V 650W Power Supply with Three 12V Rails.

Ok, i have 2x SAPPHIRE 100220L Radeon HD 2600XT 256MB 128-bit GDDR4 PCI Express x16 HDCP Ready CrossFire Supported video cards. I would like to say im on a tight budget and i know that these are probably not the greatest cards. Its all i can afford at this time. Now, with that said im having trouble with getting these cards setup into crossfire mode. I have both cards installed and the 2 bridges connected. I installed the drivers and catalyst software (version 7.7 that came with the cards). Both cards are working and show up in my hardware also. There is supposed to be and option in catalyst under the advanced or custom selection that lets you enable crossfire, but its not there at all. I even downloaded the newest version of catalyst 8.4 and still no option to enable crossfire. Has anyone ever experienced this? Any help would be greatly appreciated.

  1. Looks like no one has had this issue. Maybe someone could answer this question. This is my first crossfire setup. Does it matter which card you have the monitor connected to? Im using the bridge connectors and not a dongle (or whatever its called).
  2. Only one bridge is required for crossfire. Try removing one and make sure your monitor is plugged into your Black PCI - E slotted gfx card.
  3. Thanks for the reply. Which one do you mean by "Black"? The master card is in a white slot and the slave in a blue? Here is a link so you can see the colors:
  4. Yup, ok for your DFI mobo i mean the white pci-e slot. You've got your master in that so did you say you've have two bridges fitted atm?
  5. Yep, i have two bridges connected. Thanks again.
