motherboard What header is this?

[Callidem]

Anyone knows what connector is this one? The motherboard manual only specifies the ones right beside it. Perhaps it has something to do with the BIOS?

It reminds me of a USB header, but the missing pin is in the opposite side

The mobo is a ROG Strix B450-F Gaming II

Either some USB 2 header (maybe for wireless or bluetooth)   or some debug header (for overclockers, to read voltages, program bios etc)

It's very close to the BIOS flash memory and what's probably the microcontroller that implements flashing bios without cpu, through the usb port.

Definitely an SPI programming port for flashing the BIOS, especially given its proximity. Not really meant to be used by the end user, hence its not labeled.

Spi programming port?

How do you use it? Would be insanely helpful for me that likes to crossflash bioses rather than using shitty bios test clips or desoldering the damn ic

Take a multimeter and beep the connections to the flash chip to figure out the pinout they've used, it's likely they're pretty much directly connected.

Pretty sure it's a USB port pinout that goes straight to the BIOS chip, mainly for testing from the manufacturer

Ok i think i get it, bios chips usually only have 8 pins so i can just use an adapter for spi on a ch341 and use jumper pins, now i know that those weird 8 pin adapters are that came bundled with mine

Might have more useful info here.

Definitely seems to match the ASUS SPI-header (2x5-pin 2.0mm pitch)

And i just coincidentally finished reading that

 

No gigabyte header looks like ill need to use a shitty test clip or desolder
