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

[Rabit]

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 ?

I get myself one photos




For comparison Sapphire Rx 6700XT


Any one can help identified missing components ?

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 read can be from mosfets
bottom layer esd protection diodes I probably can go without of them due 5700Xt used 2 kinds of diodes esd131-b1-w0201 and esd5v3u1u-02lrh

Resistor are easy to measurements and they are equal to used in Rx 5700xt
Caps values I getting from Rx 5700Xt board view

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.

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 - Sot363 - On schematics from Rx 5700 show mmdt3904-7
WCM 13 - NX7002AK - SOT23 - On schematics from Rx 5700 show 2n7002e
1N - SOT-416 - BC847T no longer available to buy On schematics from Rx 5700 show mmbt3904 and is different size Sot363
GH15E - AZ1117CH-5.0TRG1 - SOT-223 On schematics from Rx 5700 show az1117ch-5.0
Fuse
B - 0.125A
P2 - 2A ? - PPTC Resettable Fuse on Rx 5700 show 1.5A

Caps
100uF 0805
22uF 0603
1uF 0402
0.1uF 0201

Resistors all 0402
0hm
100Ohm * r100 on schematics
500Ohm
1.1kOhm
2.2kOhm
10kohm
1mohm
5mohm

Can you check if my identification was correct ?

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 :/

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

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

Looks like I not notice this strapping resistors next to core damm :/

Small update on Am5 platform with new bios I can select gpu hybrid mode from bios iGPU sub menu
no longer require registry scripts or modded drivers. tested on MSI B650 with R5 7600 Windows 10

hi i got a 6700 XT with a shorted +12v_Bus and blown (burnt) c101, c102) - u are talking about shematics, do you got something for me or point me into the right direction? i need to find out what else is related to the 12v_bus sot that i can get rid of the short. traces look bad too...
Pads for C101 and so one are shorted to ground. im also thankfull for every suggestion on fixing it
