Hi all,
does anyone have the schematics for the Powercolor RX6700XT graphics card or any other RX6700XT?
Thanks

AMD Radeon RX 5700 XT (RX5700XT) Schematic & Board View
The Radeon RX 5700 XT is a high-end graphics card by AMD, launched on July 7th, 2019. Built on the 7 nm process, and based on the Navi 10 graphics processor, in its Navi 10 XT variant, the card supports DirectX 12. This ensures that all modern games will run on Radeon RX 5700 XT. The Navi 10 graphics processor is an average sized chip with a die area of 251 mm² and 10,300 million transistors. It features 2560 shading units, 160 texture mapping units, and 64 ROPs. AMD has paired 8 GB GDDR6 memory with the Radeon RX 5700 XT,... -
I just received a non working Powercolor RX5700XT Red Devil which I'm trying to repair.
Card does nothing so I dissasembled it and tested for rails.
12V is fine, as well as 5V and 3,3v.
Problem is that 1,8V and 0,75V both dead short to ground (and to each other).
I tried injecting 0,75V into the rails, but the only spot that is lightly glowing, although set to 3A, is a little spot on the edge of the APU-die.
Am I right in assuming that the APU is dead and the card is for donors or did I miss anything?
Thanks

I have 5 faulty RX570 PowerColor VGA boards. All of them have the required power rails such as 0.9V, 1.8V, 1.5V for VRAM, and 3.3V for the bus. However, there is no 3.3V EN signal going to the VCCDI/VCORE power IC — it’s an IR chip, though I don’t remember the exact model. The fan doesn’t spin either. Unfortunately, I don’t have a boardview or schematic. Please help me. Thank you very much....07-10-2025, 10:34 AM -
Hello everyone.
I’ve seen many questions related to the 1.8V EN power rail on the RX5700XT graphics card. Could everyone help gather and summarize the different cases where this power rail is lost? This would help members and readers more easily troubleshoot and fix similar issues on their own cards in the future. Thank you all!
As for me, I encountered this issue when the 1.8V EN rail was lost due to a faulty transistor Q10021. Are there any other possible cases?...
