    • Everything Just Works
Style: mATX Size: PRIME B650M-A AX
I usually get the less-featured asus board and have for years. I read reviews on this one and folks said it wouldn't run memory at 6000. It's running my expo ram at 6000 cl30 just fine. I put a 7950X in it. No issues there either. The bios let me set the TDP so I dropped it to 120W. It was nice to have a granular setting for this and not a stupid "eco mode" setting. Phoronix unigine-heaven says I'm tied for the best result with my video card (7900XT) at 2K. You really can't ask for anything more than that on a system with reduced TDP. Nothing gets hot. The onboard RGB was picked up by Linux just fine and worked with OpenRGB. I don't use the wifi or blutooth but I'm sure they are fine. Plenty of room for a huge Noctua cpu cooler. Benchmarks are fantastic. I didn't even have to update the bios. It had the most recent. The only thing I had to do in bios after turning off wifi and blutooth and setting TDP was turn on Resize Bar. For some reason it wasn't on by default. Oh, and I had to turn on EXPO for my ram. But that was it. Boom, saw the ram, overclocked it. Rarely do I build a system and it's just working the first time I hit the power button. That's how it was this time. Save your money on an AM5 build. Use this board. ... show more

    • Cant give it 5 stars
Style: ATX Size: PROART B650-CREATOR
Asus has done this to me twice now. MBs that are intermittent and act up when booting. Sometimes have to power off and try again. I got this for the features mostly so that I could run high bandwidth PCIE raid drive and still have other M2 drives with full bandwidth as well but if ASRock made a board with these features I would have bought that even at the same price. Asus has not changed since the last mistake I made with them. Overall it "works" most of the time eventually, but why do I have to keep powering off to reboot? Why? Really nice features but come on man. Get it right. Whats the use in having nice features if you are constantly fighting basic functionality like a simple software reboot instead of unplugging the power cord? ... show more

    • Worst AM5 mobo
Style: mATX Size: PRIME B650M-A AX
With an installed Corsair Vengeance DDR5 5600MHz RAM, running at either at the rated speed or at 4800MHz this mobo restarts and freezes randomly. The same memory (purchased new from Amazon) works at its rated speed in a MSI motherboard. I downloaded the ASUS BIOS updates hoping that at least one of these will be able to solve the issues (excluding the betas, there are currently 3 BIOS updates on their web site - the latest being v. 1616). It is impossible to update the BIOS using Asus EZ Flash 3 - it reads the file and after the progress bar shows up it restarts immediately without even starting the process. As a last resort I tried the Flashback option - it blinks a couple of times and then the light stayed solid green for more than an hour. No update was performed and YES, the BIOS image was renamed as per the ASUS recommendation. I used a Noctua NH-D15, which kept the CPU temperature in the low 50C (~120F). Never in my life have I ever experienced such a level of frustration with any computer related product/part. ... show more

    • Can't recommend, seeming board problems...
Style: mATX Size: PRIME B650M-A-CSM
Had this exact problem on 2 boards. RMA'd the first one back to Amazon, but 2nd board exhibited the exact same behavior. Ran 4 sticks of 8GB RAM from the compatibility list. Every time a known good stick of RAM was in the 3rd DIMM slot, Memory error and would not boot. Had to put a speaker on the motherboard to get the post codes as there are no onboard diagnostic LED's like with MSI, etc. This RAM was known good and worked fine in other systems, and any stick in the 3rd DIMM would elicit the behavior. Further, i could not get the PCIe card i was trying to use to be recognized by either board. Once again, this PCIe card worked fine in other systems. Contacted ASUS support, in the hopes that a BIOS update would fix, no avail. They didn't have a clue other than to return the board either to Amazon or them. (Their 1st tier support didn't seem to understand what a PCIe expansion card was.) The only option they offered was for me to pay to ship the board to ASUS, and i would get a known good b-stock for my trouble. That's not an option when i am paying full price for a board. So back to Amazon they all went and i am using a Asrock PG Lightning and everything just works. Too bad, ASUS' BIOS is amazing. And their in Windows tweaking utilities worked great. ... show more
