Review: Excelente placa madre. - Hasta ahora, una placa muy buena por el precio que la adquirí, la he estado usando ya por más de 2 años y va de maravilla.
Review: The bios flash feature saved me! - I've purchased this motherboards with 2X 32 gigs of DDR 5 memory sticks. Turns out that the memory sticks were high density ones and was not supported by the motherboard out of the box. I couldn't even boot the pc to get to the UEFI. This motherboard has a USB port that's dedicated for BIOS flashing. It can actually flash the motherboard BIOS without turning the PC on. I just downloaded the updated bios to a usb stick and used the flash port to get the updated firmware onto the motherboard. After I pressed the button I had to wait until the LED turned off and it was done it worked, posted and booted. I don't know if this is an industry standard or if it is for how long has it been a standard because I had been using a laptop for 8 years but I'm very happy to have this function.

### ⭐ Comes without m.2 Hardware
*by T***T on 27 December 2024*

Motherboard has multiple m.2 slots but comes with no anchors or screws to mount them. I bought m.2 drives and cannot even install them so I cant even build the PC. It has spots for the hardware but you have to buy 3rd party risers and hope they fit the non-standard holes.
