You need to pay close attention to this matter. Only if there is x16 bandwidth for both graphics cards connected to the motherboard, you will be able to achieve maximum performance.
Often, motherboards have one main x16 connector and several subsidiary ones with lower bandwidth. It can be x8 or x4. But it is not enough just to have two GPU connectors on the motherboard, it should support the CrossFire functionality at the chip level. It is also worth noting that only motherboards that have AMD and Intel chips are able to work with the CrossFire technology. If the motherboard is made on an Nvidia chip a company that is a direct competitor to AMD , it definitely does not support the patented CrossFire technology.
Ideally you should use two identical graphics cards — of the same series and from the same manufacturer — to combine them into an array through CrossFire. But this is not always possible, so on the AMD website, as well as on the websites of graphics card manufacturers, you can find detailed tables with compatibility of various graphics processors between each other.
Important: If the cards are compatible to operate on CrossFire, but one of them is more powerful than the other, you should know that a more powerful model will not be able to fully reveal its potential. Both cards will work at the level of two weak cards from this pair. It is worth noting that in the same package with graphics cards that support CrossFire, there will necessarily come a bridge that can be used to unite them.
It is a small cable with the corresponding logo and connectors on both sides. Power Supply. The concept of a multi-GPU setup was all the rage in the s. Since that time, the list of CrossFire compatible cards has grown exponentially but the technology itself ultimately hit a wall. Read on to find out what CrossFire is and what exactly went wrong. The dream of having multiple graphics cards hooked into one PC and utilizing the power of those cards at the same time seemed like a crazy idea.
AMD soon followed suit in However, the drawbacks of both technologies persisted and ultimately led to their demise. This sequence of events was caused by two main factors: that the two graphics cards needed to be specifically optimized by the game developers and, more importantly, the fact that these technologies never delivered anywhere near double the performance.

I assumed it didn't really matter which card I plugged my HDMI cable into, so I just stuck it into one the bottom, second slot one and it seemed to work.
But I realized it wasn't showing the splash screen and the options to boot into BIOS that I normally see when I start up my computer; my monitor just wouldn't show anything until it got to the Windows login screen.
But when I got out of the BIOS and started my computer up normally, I had to switch back to the other, original card for anything to be displayed. So--in short, one card will exclusively display the BIOS and startup screen when plugged into; the other will only display Windows once I'm booted up.
Why is this happening, and how can I make it so one card is able to display everything? Thanks for the help, everyone. Dec 9, 15, 1 57, 1, This will change which card will be the primary card. It is possible that your bios will only be seen from the top slot, then use Init PCIe slot once you are past the splash screen. Another possibility is that you need to disable crossfire, shut down, plug your cables into the top slot, start up and install your AMD drivers.
Then re-enable crossfire. I'm leaning towards the 1st one to be the issue. Aug 20, 2, 0 21, First of all, have you to make sure your crossfire is enabled: 1. Have you put the crossfire bridge between the two ? Have you enabled crossfire in Catalyst? Mar 10, 79 0 18, 5. I don't think you understand--Crossfire is enabled, I get greatly increased performance in games and I've taken both of those steps.
My issue is different--read the post please. I read it. If you turn sour because I made a suggestion which you could have answered with simple "yes, I am sure", then I am out of here.
