XFX RX 580 GTS Repair #2 - Not detected

[@chris_hertford]

The way the GPU market is at the moment GPU repairs are a hot topic right now! Good timing to grow the channel, keep the videos coming they are very informative thanks!

[@killstreakpinterest8954]

wait a minute I thought I already like this video... Oh wait, this is the second RX 580 video from Tech in one day!

[@yoyo3136]

Yes another one! A week is too long! Thanks !

[@yoyo3136]

I can supply you with AMD card. If you are interested : got a Vega 56, rx 580 8gb, rx 570.

[@TechCemetery]

Thanks for the offer, if I take you up on it I'll let you know.

[@yosuhara]

Two videos at once? Bless you!

[@danandrei96]

Man you have amazing timing! Not only are the Polaris cards in crazy demand right now due to the mining boom, but I actually have an XFX card with the exact same PCB that I've been working on, I messaged you on reddit about it a while back. Thanks again for the great videos you posted today!

[@TechCemetery]

How is that XFX 580?. What voltage rail(s) are you missing if any?.

[@danandrei96]

@@TechCemetery so it seems I have 12V, 3.3V, 5V and 1.8V, but I'm missing the display rail, where I get 0V. Resistance there is 25ohm so not shorted. Honestly I had put the card aside since I have other stuff to work on but now that I know that's where I need to look I have a better chance of getting it fixed EDIT: technically it's a 570 but PCB is identical

[@TechCemetery]

Good to hear, on some cards they use a GS9238 instead of an APW8713 for the display rail. Good luck with the card and let me know how it goes.

[@danandrei96]

@@TechCemetery I have the APW chip on my XFX card. For testing purposes, can I replace it with the GS9238 chip or do they have different pinouts? I can't seem to find the APW chip on any of my other cards

[@TechCemetery]

Excellent repair! Thanks a lot.

[@trouble_maker023]

Micron has very high vmem resistances, on a r9 270x I had 500ohms as well, the strange thing is, that this only occurs with that brand other chips are in the rage of 20-40 ohms

[@PaulHigginbothamSr]

I can remember when I thought this card was huge and over the top. Now an rtx 3090 ti pulling 400 watts being a room heater and hopefully a power supply that pulls down the house voltage when clicked on. And when the phases short with no fuse welding completely through a thick board with burnt carbon and no way to fix, well I go for this card instead.

[@alanrivas2443]

Hi, I need help for an identical graphics card, at the output point of the b1117-adj it measures 3.2v and 553ohms but it does not turn on the mosfets, do you have a tip to check?

[@bngh12ful]

There are 2 resostors connected, and they can be adjusted or just replace adj

[@vlada7474]

You did great work, I appreciate it. I have one faulty card, xfx rx 580, and, as you explained, I measured resistance on the main points, so I found 0.7 (short circuit, I think) at Vddci. Bus voltage between memory and GPU core might be a heavy fault, or might be some another element in parallel. No burnt components were found. Any suggestions for the next step? Thanks a lot.

Hi, I'm from Colombia, what good videos I have a question does the APL5932A have a 3.3v output?

[@TechCemetery]

I don't believe so, PWROK ( Pin 1) is considered an output, but as far as I can tell, it's boosted to 3.3V by the PCIe slot through a 10k ohm resistor. If you have 3.3V on pin 5, you should be worried.

Hi man. Very good and useful video, continue like this. When I check 12 volts on PSI ,I get 0.33v, and at 3.3 I get 0.145v. The card works but the image freezes. Can the problem be with the memory chips, the CPU or something else .... your opinion.Thanks and this would help me a lot:::

On this same card, I’m not getting any volts on the 1.18. I do have the 3.3 and 5v going in. Nothing on the mem or mem controller. And nothing at the v rail. Do you think you could help me?

[@TechCemetery]

Use the datasheet and check VCntl, EN, and VIN. They should be 5V, 3.3V, and 3.3V respectively. Let me know if you're missing any of them.

[@ZoeyForPresident]

@@TechCemetery hey thanks for the reply! I’m not getting anything at the EN. I should mention that I got this card second hand and the previous owner plugger a riser into the pcie backwards. So it definitely shorted something out. :)

[@accurian148]

Well i got the powercolor RX 570 with the exact same problem as this video. I managed to solve everything exactly same as you until at this point im at the final part, the buck converter. Does vin and vcc always connected directly with 3.3v? If yes then well i have to order that buck converter. Edit : when the display rail is not present, the other voltages are showing normally and chip is getting hot. Oh also the owner mentioned before the card die like this it sometimes work and sometimes didn't.

[@TechCemetery]

VIN and VCC are not always 3.3V, I believe on some cards VCC is 5V. As for having every other power rail, on a Sapphire Nitro RX 580 the memory and memory controller can't power on without the PGOOD signal from the display rail buck converter. Where the GPU VRM doesn't turn on unless the memory VRM has a 1.5V output. I'm a little surprised your card powers the memory, GPU, and memory controller without the display rail.

[@accurian148]

@@TechCemetery POK does exist 3.3v, yes I'm also surprised when the gpu chip is getting hot and all voltages rail does exist except the display rail. Looks like everything is clear now and i need to wait for the buck converter, thanks for your help!

@@TechCemetery well turns out the pull up from POK to VCC is dead, i replace it with a good one now it's showing normal 900mv. But here's the situation, the memory 1.5v is missing and rest of the voltage rail only appears when the bios is posting, when it beeps and boot all voltage rails are gone. Any ideas why? This probably gonna be my last attempt before give up, thanks. The resistance from memory to ground is 17 ohm which is pretty normal i think, and it's the samsung memory.
