Question GPUs not working in old motherboard

[marktwayne]

I have an MSI H77MA-G43 motherboard with an Intel i7-3770, 32GB of RAM, and a 1000-watt power supply. Years ago, I was running two Radeon RX 580 GPUs in crossfire mode. At one point, I started experiencing crashes and the computer stopped detecting the RX 580s. However, it did recognize an RX 460, and I was able to use the computer for a couple of years until it also stopped detecting the RX 460.

As a result, I replaced the motherboard with a used one. At that time, I had already sold the RX 580s and was using the RX 460 in my computer. Recently, I decided to upgrade my graphics card. Initially, I tried installing an NVidia RTX 2070. Although the card was detected in the device manager and displayed video, the device manager showed an exclamation point in a yellow triangle and the display only worked with the Microsoft Basic Adapter. GPU-Z identified the card as having 0 memory. I then attempted to install an RX 5700xt, which also encountered similar problems. Unfortunately, I do not have another system to test these GPUs, but I suspect it may be possible that the graphics cards are functioning correctly and the issue lies elsewhere.

The board operates on PCIE 3.0 and I have the latest BIOS, version 1.D, dated October 2013. To the best of my knowledge, there should not be any compatibility issues between this board and these cards. Is it more likely that both GPUs are faulty, or could there be another issue? The RX 460 is still functioning properly.

brand and model of the 1000w psu?

Rosewill Glacier 80 Plus Bronze

I have a few other power supplies, such as a Thermaltake 1500w Toughpower Gold as well as a 650-watt PSU if you think that's a likely culprit.

Never heard of Rosewill Glacier 80 Plus Bronze PSU before and seems like this PSU is cheap. I think you shoud try 1500W PSU out with those GPU

I tested the 1500W power supply and obtained the same results. I have seen many people with older computers successfully run new graphics cards; however, the only recent card that my motherboard has recognized is the Intel Arc 770. In GPU tests, this GPU performed in the bottom 11% among other cards of the same make and model, and it caused my computer to crash when I used video editing software. These issues, along with the failure to recognize other new cards, make me wonder: is it possible that my motherboard is simply not compatible with most newer cards? I am using the latest BIOS (1.D), but that is from 2013.

Does your mobo have rebar?

I think its less likely its your PSU and much more likely its your motherboard. Hard to say what the specific issue is, but my guess would be one of your PCI lanes has an issue. Rosewill PSU's are fine.

It's always hit and miss with newer AMD GPU's past the RX 470 and the RX 480. I have had good results using legacy setting in older bios but still it's a roll of the dice. Some work and some just flat out refuse to work.

What's odd is your old motherboard could use the RX 580. What mode was BIOS in on the old motherboard UEFI or Legacy. On those early UEFI board I have better luck getting the RX 580 working in Legacy.

RX480 specifically has some issues with motherboard compatibility. Ran into that problem myself. Its definitely weird that the 480 was the one card that DID work.
