I traded my cousin some really expensive RAM that I happened accross for his old desktop, that he put his graphics card into that he swapped from his newer computer. If I plug the desktop into the wall and try to turn it on nothing happens. If I open it up I can see that the where the wire from the power supply plugs into the motherboard there Is a little light on. So clearly some power is getting somewhere…
How do I go about trouble shooting this, and what tools do I need? I assume at minimum a multi meter? Not really sure what to do, it’s been decades the last time I built a computer.
The MB probably doesn’t jive with the GPU. Look up online for the MB manufacturer if it supports that sort of GPU.
If your RAM is seated as 1 and 2, make it 1 and 3 or 2 and 4.
Fans usually means the BIOS is recognizing some hardware as funky. I had this same issue when I bought RAM that was incompatible with my MB.
Unless the GPU is an Arc, compatibility between the motherboard and GPU shouldn’t affect much more than the maximum performance you can squeeze out of the GPU. As a protocol, PCIe is backwards compatible.
Never assume. RTFM when trying to use dual channel memory.
