RX 6700 XT Reference dead ming cards

I can buy bunch of them at 1/3 price of second hand ones but can preliminary test them/ select best if I not touch amd warranty seal on heatsink screw, I can remove back-plate
In first batch I see 2 with dead short on 12V molex and when injecting voltage I see no voltage leak to output caps here some resistance values on output caps Red is from working Sapphire RX 6700 10Gb due sharing this same PCB layout I suspicious of blue one is no repairable due low resistance

Hm... after some thoughts this can be also due I assembled this LCD from two broken one have burn out electronics other broken LCD panel, both this same model but different month of production and inside electronic have small differences. In end is possible this led strap is not compatible, sadly no HDR for me .

Caps looks fine I tested some in circuit and shows proper values also I isolated secondary cap for led and hold values.
Visually I only slightly discolouration yellow tape on LED transformer, in real life looks more prominent.
I drilled some holes in IO shield for better airflow, bottom and TOP on photo only bottom showed.
Hm I wonder if this can be some failing insulation or poor connection and when Voltage increase for better brightens I getting heating in corner, I have two LED connectors and only one side getting HOT....

VX3276-2K-mhd-2 Random Turning off

Recently staring turning off more often, brightens set at 50% - monitor back side in PSU area is very warm to touch, also at front left corner getting hot.
When changed brightens set at 30% no longer turning off , and no longer I can feel any heat in this areas.

This can be signs of bad capacitors causing overheating PSU ?

I also seen Polish YouTuber who fixing GPUs have similar issue with this GPU model a year ago [url]https://youtu.be/bBd6wNAiyyI?t=423[/url]

Edit never mind gpu packaged failed looks like factory defect shows its ugly side after all this time.

Looking for AMD RX 6800 Reference BoardView

As in topic I have RX 6800 without 1.8V line and will be happy if someone have schematics

Re: Sapphire GPRO X080 (RX 6700) anyone try add video output ?

I manage find alternative solution using iGPU on CPU to output image via motherboard HDMI.

[url]https://community.amd.com/t5/drivers-software/igpu-dgpu-not-working-on-windows-11/td-p/593745[/url]

This register tweak add switchable GPU option that is present in laptops to desktop now my mining GPU work in all games.

Some OC I change bios to standard Rx 6700 and UV 1.07V OC +15%TDP

Re: Sapphire GPRO X080 (RX 6700) anyone try add video output ?

Update:

GPU chip have laser off sense pin for detection if monitors is plugged on all ports, I know because I put all smd *( even freaking 0201) and display ports on board and not worked and only after this I notice it I been fooled due all data signal pins are still connected and have correct resistance values :/

Re: Sapphire GPRO X080 (RX 6700) anyone try add video output ?

I think add top 2 display ports due schematic that I have from Rx 5700 full info and RX 6700 only info about resistors and capacitors, but they they have different values for capacitors on bottom display port and one of smd needed for HDMI is no longer available to buy, values of capacitors, resistors I getting from schematics.

Before I order parts please check this SMD that I identified:
K27E 7 - 2n7002dw - Sot363 - Panjit On schematics from Rx 5700 show 2n7002dw
MA 76 6 - MBT3904DW1T1G -...

I plug my faithful M-tester to unknown part looks like dual diode.

I also test N-channel trench mosfet that was next to, but detect as normal N-channel....

Re: Sapphire GPRO X080 (RX 6700) anyone try add video output ?

I borrowed from a friend Rx 6700xt to make some measerments

Close up

I recognized parts thanks to comparison to Rx 5700Xt board view

GH15E - AZ1117CH-5.0 x1 BCD Semiconductor
K27E 7 2n7002dw Sot23-6 x7
MA 76 6 MMDT3904-7-F x3
WCM 13 2n7002l x4 Nexperia
1N x1 3 pady - I do no know what this is ???

I have also some diodes any advice ??
Top layer this can false identification due diodes...

I asking because I can get myself new one unused for half price of Rx 6600xt.

From photo their pcb looks like Sapphire RX 6700 10Gb but missing video outputs.

I have some experience with soldering, I only concern about what smd parts to gets and if I can Flash Bios on it ?

Any one know list of needed smd parts caps/ resistors for HDMI and Dispaly ports ?

Re: Msi B550M PRO-VDH Identified Missing Components

My flux is some chine cheap paste staff my solders splatters everywhere , I have hot air but not much experience with.
93ohm change to 53ohm but this can be due repairing broken trace.
also 10k ohm show 9.6k but testing now under stress test Furmark dGPU Rx 470 + CPUz stress test for CPU and is stable, previous owner have instant crash when stress dGPU Rx 5700xt

I ordered some PVB-60 Varnish from AG Chemia because was cheaper than solder-mask

Re: Msi B550M PRO-VDH Identified Missing Components

After my fix board booting to bios I check full load stability tomorrow.
And buy something to cover exposed traces.

Once more thanks....
