How important is P_GFX_TXN[9]?

[K4sum1]

I bought a used 5950X with bent pins, however one of the pins is broken, and that pin is P_GFX_TXN[9]. I'm wondering how important it is and if I might need to find someone that can replace it

Do you get any errors, does it boot up?

I have to wait for it to ship to me.

Does the current owner say it boots up.

I had a desktop with a 7700k with 1 missing pin, it would boot up and some programs wouldn't start.

Here is a pin layout for AM4

He had bent some pins, and apparently hasn't tried to bend them back, and just listed the chip online.

I had a CPU witha broken pin. wouldnt even boot was an AM2 system IIRC. cut a staple to length and put it in the socket where the pin was supposed to be. Worked mint and lasted years. There are proper ways to repair with like a heatgun and solder if you have the know how and spare pins.

The machine might just boot and work. Not sure what that pin does specifically though.

I looked at guides, my assumption is iGPU. I also thought it could be PCIe lanes, but there's not enough of them for it to be that. If it does prevent startup, I could try stealing pins from a dead AM2 CPU or a DP0 pin.

For what its worth my first thought was iGPU as well.

the 5950x doesnt have a igpu.

the 5950x doesnt have a igpu.

The pinout is generic, I say that because it would likely be for an iGPU on a chip with that.

Found something here:

Socket AM4 - AMD - WikiChip

AM4 is a socket for AMD's mainstream series of microprocessors, serving as a successor to Socket FM2+ and Socket AM3+. It was superseded by Socket AM5.

en.wikichip.org

Its not exactly the same but could be a hint...

P_GFX_TXP/TXN[15:0] = PCIe GFX Transmit Data Differential Pairs

Dont forget that these chips today are SoC type (system on chip) and communicate directly to a lot of system parts, like the PCI-E GPU
