Based on what I know, any GPU will work in all PCIE slot. No matter if that is DDR2 or DDR3 system.
So I found this old GPU, https://www.gigabyte.com/Graphics-Card/GV-RX30HM256DP-RH#ov
The problem is, GPU will work and display in my DDR2 system, but when I try to install it on my DDR3 system, the GPU will not display.
My DDR3 system is work well with another GPU (AMD R7 250X), so that's not motherboard issue.
I know the GPU is old, I just want to use this GPU for display only. I just want to know why the GPU not work.
