    Great value, works great, weak packing shipping

    Mobo cpu fired up easily with ubuntu after bios reset. Box arrived a little mangled because cpu cooler was mounted and is taller than box dimensions. Should have put CPU cooler beside mobo wrapped separately.

    Spins like a top

    Purchased this as a direct replacement for one that had been performing well but crapped out when the power supply went, taking the hard drive with it as well. Received well packaged, fired right up and flash bios to accept my newer CPU, windows so it was different so I had to reactivate but that went smoothly. Motherboard is a great value to keep an old system going.

    Great Motherboard

    I used this board with my AMD 9650 Quad core CPU. It performed great. Using it for my Media Center computer. Plays movies great. Couldn't be happier with it.

    Good to Go!

    Needed this to replace a board that quit after aprox 5 years of more or less 24/7 useage. Turned the old system off and it wouldn't even POST again. Ordered this board as a on-to-one replacement and it worked just fine. Windows 10 needed to be re-activated but that too, was no problem. It's just a nice board and runs good enough to do some light video editing and gaming.
