    • Good board for the money, no frills, it works. Good board for the money, no frills, it works.

Works as it should. Like new condition. (I bought it refurbished) good board for the money. Bios is up to date enough for ryzen 9 builds without having to update. No frills on this board, only rbg is on the lower right of the board. Hidden behind the gfx card in my build. No other rbg on the board itself. Some want it some hate it. This is the meh in between for it ;) ... show more

    • Mommy's favorite motherboard
I have three operating systems running on this device using the ryzen 5 3500 and a MSI Radeon GPU. Mac OS Windows 11 and Ubuntu. Nowadays the price shouldn't cost about $300 or more slightly.

    • Works well with Ryzen 5900XT and Ubuntu
Board works well with my cursed 5900XT. Reasonable settings in BIOS (eg. virtualization on), nicer BIOS interface than some other brands. Went the easy way of disabling secureboot so that the amdgpu driver for linux would load, otherwise it wouldn't ... so that security measure works. USB-C port provides enough power to run a USB-C monitor. Both NVMe slots would happily sustain over 2500MB/s so loading large LLMs is fairly quick - 10s or less to load a model that would fit on any consumer GPU. Fan connectors seem to be better positioned and labeled than with other brands, and there appear to be both 3-pin and 4-pin RGB LED connectors if you're into that sort of thing, And a switch to turn all that stuff off, if you're not. ... show more

    • Not bad for a refurb...
Its just the mainboard, and a driver cd, nothing else. No sata cables, no m.2 screws , and it is a refurb ,that being said . Board was pristine looking and well packed. Worked just fine.

Very easy to install, once I got it in, fired right up. However, there is one thing I wish I knew prior to purchase. I wanted to install a third SSD M2 drive and since you can only install two in the board, I used an adapter card that goes into the second PCI-E card slot normally used for a second video card in SLI configuration. However, after unsuccessfully trying to get the card recognized in Windows I discovered that if you use the secondary SSD M2 slot, then that card slot won't work. It would have been nice if I could have used it, but that was my error for not doing more research. The motherboard is indeed a great value for the price I paid. ... show more

    • This board is great for gaming
I bought this board and a 5600x to go with it only because I didn't have the funds for a 5700x or 5800x at the time but I've been using it for the last several months since I put it all together and I've had zero issues with it. Had to download the manual off their site which I highly recommend makes this clear cut on how to wire. After that things went together really fast runs like a champ nand it Even has some rgb lighting on the board it self which was kinda cool ... show more
