There was a problem filtering reviews right now. Please try again later.
I then just bought it new and it's been great.
It requires some patience on first boot since the FW seems to "think" a long time without writing to the screen, but it eventually came to the BIOS splash screen. I did update the BIOS to the latest version right away since the shipping version was outdated (may have been fine but why take chances). The BIOS update procedure is simple--just download, unzip to a connected drive, boot to the UEFI BIOS, go to update BIOS mode, reboot, and point to the BIOS file on the connected drive. The update process will finish up and the system will reboot. I did have to set the memory speed to the profile to support its speed--it did not automatically choose the correct JDEC/XMP profile for 1600MHz/3200MT/s.
After installing Windows 11 Pro and my application/utility suites, the system has been stable through some very heavy use: transcoding videos with CPU and GPU using Handbrake, creating/editing videos using DaVinci Resolve, editing photos with Lightroom/ACR/Photoshop, and running a range of development and productivity applications. CPU-z confirms that PCIe is running at Gen4 speeds, and the memory is running at the correct profile/speed.
In all, the motherboard is a good value for the performance and stability that it delivers.
Weird RAM installation. This mobo is a little different from my previous one in the ram slots. Instead of two latches, it only has one latch. The one latch made it really difficult to install my ram and get it out. Once I was installing my AIO and it kinda get in the way of the RAM, I found out I put my ram in incompatible slots so I need to switch em out; getting one ram stick out was just hell, and the other just refuse to go out despite the latch is unlocked.
Overall it’s a great mobo but damn, installing ram is just unnecessarily difficult.
This motherboard comes with a BIOS flashback feature, but mine came with a Ryzen 5000 ready sticker on the box and sure enough, I didn't need to flash the bios to get it to work with my 5600. Something to note is that the DIMM slots only have the locking tab on one side and are rather hard to get your memory sticks seated properly.

Je n'ai donc pu mettre en service mon PC, je suis d'ailleurs inquiet en ce qui concerne les dates de retour qui vont être limite en cas de dysfonctionnement.
M. Le Gallou
Reconoció el Ryzen 5 3600 inmediatamente, no hizo falta actulizar BIOS. También le instalé una memoria RAM de 3200 Mhz, pero para que la reconociera si tuve que entrar en la BIOS y configurar la RAM en la frecuencia correcta. Esta tarjeta madre tiene muchas opciones para configuraciones avanzadas. La BIOS tiene dos formas, la forma normal en la que entras, y la forma avanzada a la que entras presionan F7. En la forma avanzada de la BIOS es que se puede hacer overclocking, y es donde se puede configurar para que te reconozca la RAM con la frecuencia correcta. Además en la forma avanzada de la BIOS puedes configurar también las curvas de los ventiladores, para que giren más rápido, entre otras cosas.
Nunca he hecho overclocking con este procesador, porque no lo he visto necesario. El procesador llega por su cuenta a 4.2 Ghz con el boost de AMD, así que no me molesto haciendo overclocking.
De verdad que es una buena tarjeta madre, bastante sólida, con muchas opciones de configuración, 8 puertos USB para el que le interese, y además de una marca respetable y con garantía.
