Re: Asus Flashback AI1316 Schematic

Just for completeness, i was able to remove AI1316 and bridge it.
Only missing piece is SPI-Vcc switching which i wasn't able to figure out.

See attached image for more details.

bridged pins from left to right:
CPU DI | SPI DO
CPU CLK | SPI CLK
CPU CS | SPI CS
CPU DO | SPI DI

2 Gates beneath TPM-Header:

..... HOLD CPU ....... WP CPU
HOLD SPI ..... WP SPI...

Hello,
i'm currently in the process of debugging an ASUS STRIX X570-F GAMING and experiencing no activity on the SPI_D0-line to the bios chip.
I expect the AI1316 to be dead and want to remove it (and bridge the corresponding pins).

Before measuring everything out - has someone a schematic of this board or any other with one of these flashback-mcus so i can just refer to the schematic?

Kind regards

Re: Palit Geforce GTX 1080TI - not detecting PEX Power



- Fuses are all good
- rails and voltages are ok
- no pieces missing

I have a spare pcb (defect, missing components and gpu) to take parts from and compare.

I suspect something in the INPUT_PEX8_DT <----> GPIO path to be fishy.

What reasons are possible for causing the corresponding bios-message?
I thought without working NVVDD the card would not turn the screen on and the board is load balancing between PEX1,2 and PCiE?

I'm...

Hi,

i've got a Palit GTX1080TI Blower with which someone previously tampered and tried to repair it.
Fortunately, it enables the screen, so gpu and stuff seems intact. Powerrails also ok. Only problem is: Despite of having connected both power connectors, it complains that PEX-Power is missing (on screen message, like cables are physically missing) and refuses to boot.

I already asked for boardviews in another thread, which should allow me to better check everything.

But despite of that, any ideas where to start looking?

Kind regards...

Re: Graphics card Schematics and Boardviews

edit: pcb looks 95% identical to Nvidia FE, but without pads for missing parts and thus slightly different layout.
so FE-Boardview would also help.

Hello,

I'm currently trying to repair a Palit Geforce 1080ti Blower.
Does anyone have a boardview / schematic?

Kind regards

Hello!

I'm an electronic and computer hobbyist and into this stuff since my childhood.
Right now i'm trying to start fixing GPUs.

thank you all for your hard work and effort to make this information accessible!
