Review: Reliable and fast speeds on the regular. - On time shipping and very quick setup for the BIOS and loading drivers. Great for a first time PC build for those looking to get modern computer at a reasonable price. 2 NVME m.2 drive slots and plenty of Sata drive slot for raid array.
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.

### ⭐ BROKEN
*by T***K on April 10, 2025*

I got mine with already bent pins, and apparently it’s a common problem! DO NOT BUY. If you were looking for a warning sign, this is it. It doesn’t even have LEDs for diagnosis. Do. Not. Buy.
