For a high enough configuration having the B550 chipset ensures at least the right hardware. I'm far from being an expert but I used to have a B450 chipset and I wasn't sure if I had what it takes to hold a big processor so I switched. The little plus of this motherboard is that it integrates bluetooth as well as wifi so no need to add a PCI wireless network card
Need to flash the BIOS with the bare motherboard, no problems encountered.
Be careful with RAM settings if you use high frequency RAM
I was quite excited about the number of features at an affordable price, but I'm having problems, updating the bios causes the Bluetooth built into the motherboard to bug, I sent the board back and the same problem with the xmp failing.
At first everything is fine, the card has all the functions you could wish for. Then the cold shower arrives.
Twice the PC does not turn on, no LED, no fan, nothing. Solution found on Reddit, remove the battery, wait and put the battery back. I have to redo all the bios settings, not good for a card at this price.
Maj of the bios hoping that the IO problems will be fixed, now the usb ports connect and disconnect randomly. Again, a quick look on Reddit, I'm not an isolated case.
Move on, on paper the card is great but it doesn't even handle the base.
I'm not sure if I'm going to be able to use it, but I'm sure I'll be able to use it again, and I'm sure I'll be able to use it again. I'm not sure if it's a good idea to use the CM, but I'm sure it's a good idea to use the CM, and I'm sure it's a good idea to use the CM, and I'm sure it's a good idea to use the CM.
I'm not sure if it's the same or not, but it's a good one.
I bought this motherboard for the following reasons:
- No fan needed to cool the chipset (unlike the X570 based CM)
- Enough case fan connectors (and all PWM)
- Sufficient number of USB ports (many CMs have less USB ports)
- A nice and already mounted front panel (it's much more comfortable when integrating into the case)
- WiFi and bluetooth support
- Reasonable price for all the above mentioned features.
What I liked when I unpacked it was the quality of the PCB and the on-board coolers.
I put in a Ryzen 7 3800X, an MSI GEFORCE RTX2070 Ventus GP graphics card, 16 GB (2x8GB) of G.Skill Ripjaws 5 Black Series CL14 memory, a Samsung EVO970 plus 1 TB hard drive.
No problems encountered, the format of the CM is such that the assembly of the elements is easy. The PC booted on the first try, the graphics card worked straight away.
Update of the bios from F1 to F2 using the AORUS @Bios utility was done without any problem even if this software seems to come from prehistory!
Very easy to select the XMP profile of the DDR4 in the bios.
In use, the system is robust and stable (no crashes even when I run GPU and CPU stress tests).
I'm not a fan of overclocking so I can't say anything about this CM because I haven't tried to overclock the processor. On the other hand, the bios are full of options for overclocking!
Usage: gaming, office, movie watching, internet surfing,
The default PWM fan management is very good, the system is very quiet and the temperatures are very correct.)
I recommend this motherboard: cheaper and quieter than its predecessors based on X570 chipset, more complete in my opinion than other CM based on B550 chipset!
Excellent and beautiful motherboard, very complete. Very powerful and supports overclocking well. The only downside is that the M.2 SSD heatsinks make noise when not in use. A plastic washer to wedge them would have been a good idea.
