Need help with setting up Crossfire using AMD HD7750

Rangan Das · May 24, 2015

I made a build on a Gigabyte 970A-DS3P motherboard - AMD FX8320, 8GB DDR3 RAM, 500W PSU.

At this moment, I got a Radeon 7750 on a PCIe X16 lane. There is a free PCIe X4 lane on the board. Can I add another 7750 and use them simultaneously (in Crossfire config)?

Also, will I need to change the PSU?

no. the second GPU will not fit inside the slot.

But both the slots actually look the same.
I have never actually tried putting the GPU on the X4 lane though. You can have a look at the board here. You can see the blue PCIe slot on the left is marked as as X4 slot.

It will fit just fine and that PSU wattage should be fine as well. The only difference in those PCI-e slots is their bandwidth.
