Hi,
This is not an issue, just to share my experience and some links.
Based on:
I searched for the R560 resistance and a socket for a standard RTC battery (this was the hard part because nvidia refers to the connector Wieson Technologies AC2651-0011-003-HH, 2-pin, 1.25 mm pitch), to have it a bit cleaner than solder directly the battery cables on the carrier board.
I found and bought these:
- https://es.farnell.com/molex/53398-0271/conector-macho-2pos-1-fila-1-25mm/dp/1125366 (Molex reference 53398-0271)
- https://es.farnell.com/panasonic/erj2bqfr56x/res-detec-corriente-aec-q200-0r56/dp/2799620 (Panasonic reference ERJ2BQFR56X)
- https://www.amazon.es/dp/B09F38WVWH (ensure the conector type is Molex 51021-0200)
I’m sure people can find them on any international website.

After:
The soldering result is not profesional but it works, I tried a heat gun but no luck, the resistor y very small.
I finally did it with a normal soldering iron, but it cost me a lot for the 3 GND pads of the socket, because it seems to dissipate the heat very fast…
Hope this can help.
I have now the clock handled with the RTC battery (when not connected to a NTP server via internet).
