[SOLVED] Can a PCIe 4.0 graphics card work on a PCIe 3.0 slot?

[yozie]

I'm planning to buy RX 5700 XT (pcie 4) but does it work on a pcie3 motherboard? Will there be any compatibility issues or issues in general running on pcie3 only? thanks in advance

My motherboard is X470. Here is the model https://www.gigabyte.com/Motherboard/X470-AORUS-ULTRA-GAMING-rev-10#kf

Considering a PCIe 3.0 GPU can run on a PCIe 2.0 slot, I doubt that backwards compatibility has been compromised with this new generation.

yes it will work.
PCIe 4 has more throughput but few cards actually need it yet.

I'm not sure about your board but it looks good that your board might support PCIe4 with a CPU change.

Thanks for the response. I'm still not confident updating my bios because from what I've heard a tiny mistake could lead to bricking my entire motherboard, so i tend to avoid updating/changing bios.

the biggest issue when flashing a BIOS is power. if you need to borrow one a UPS is the solution to the power problem.
RTFM
Read the full manual - family friendly translation. an ounce of prevention is worth a pound of cure, or a pound of motherboard as it were. 22 years fixing PC's and I have had one bad bios flash and it was a guess what? power issue, brown out while writing to the EEPROM.
