Crossfire issue

[Jack451]

Mobo : asrock b450 steel legend atx version

cpu : ryzen 5 3500x

ram : hyper x 3200 2x8gb

ssd : adata sx6000 256gb

hdd : seagate barracuda green 2tb

psu : gigabytes superb 720 (old psu from an old pc)

gpu : msi gaming x 570 4gb x 2

 

So this is a build from 2-3years ago and don’t want to upgrade it, the second gpu was given me by my cousin and wanted to crossfire but the system doesn’t recognise the second gpu. I try to check everything on the internet and could not find it so I need some help.

Welcome to the forums!!!

 

Crossfire is a dead technology unless you're doing computations or high-level graphics (not games), then is not worth it as most games today are dropping SLI/Crossfire support. 

Both graphics cards have to be ideally, identical to each other for it to work well. There are other requirements such as being from the same family of GPU architecture and model.

Both of them is exactly the same but window couldn’t recognise the 2nd gpu

First replace this 15 year old dinosaur. It's not reliable anymore (if it ever was)

With 504w @12v it never can be a 720w PSU.

Cf is mentioned in the spec but CF works terrible on the 4 chipset lanes available for the 2nd GPU. Latency is skyhigh.

 

Which version of the GPU driver is installed?

Nvm I think I sorted this out with its manual book. So basically my pcie4 been disabled cause my m.2 in the first slot has been used after I put in my second m.2 slot it registered my gpu. Will change the psu later. Thx btw and the gpu is update via amd software adrenaline edition 22.8.2 ?
