ASRock B850M-X AM5 AMD B850 SATA 6Gb/s Micro ATX Motherboard

Mine came without an IO back plate. I was told to call a number, that then told me to send an email asking for one. The emails was replied to two days later that they were "out" of them. I admit, I was so disgusted I threw the board out. I'll not buy Asrock again.

complete package in the box. arrived on time

This is a review for the B850m-X Non-Wifi, the "successor" to the B650m-HDV. As I do not own the Wi-Fi version, I cannot speak on if the chip is MediaTek, etc., but it usually is some sort of MediaTek Wi-Fi chip that is sold across the ASRock lineups; you may be able to Google it. I've attached a photo where I am unable to run this board at 8000 MHz with 2×24 GB Teamgroup Expert M-Die. This means the board does at least qualify for the 8000 MHz mark, especially reboot stable in my case. I didn't have to type in ODTs/etc., and the board takes its own sweet time rebooting—which was still faster than the HDV and other brands in my experience, with memory context restore off, etc. The timings and such are still being tightened; however, it's been stress tested on Y-Cruncher VT3/FFT, TM5 Usmus3, Karhu, and Memtestpro for over 3 hours each while being in a case with a looping stress test. As with Asrock, their BIOSes are fairly clean and are straight to the point—maybe not as modern as Asus or MSI's. There are no compatibility problems with any CPUs I am aware of; there is one point I would like to bring out for those who want to go further: The board does not support PBO advanced/manual. You are only able to "enable" PBO and use the presets; however, if you are using the 9800×3D, you cannot manually use PBO to set a higher overclock on the cores or negative voltages. Hence the rating I gave to the board; I indeed contacted Asrock, and you can even use other software to manually do PBO, but it's not really worth it, IMO. Asrock declined it so far, but they may change it by this review. There does not seem to be any throttling for a 9800x3d, temperature or power wise. Performance is on par, if not slightly better than other boards past the 250$ mark in my experience (Tomahawk/Asus Strix series). There are no problems with the board or BIOS except for what I mentioned above; it's the "go ahead" motherboard for those needing a relatively cheap and 'what you need' feature set. Because of my own experience, I would suggest Asrock over other brands primarily because of the reboot speeds, a fairly easier overclocking experience, and value. I hope Asrock will take a listen on unlocking PBO and setting up other future boards just like this!

Worked with the Ryzen 7 8700g out of the box, plenty of fan headers and nice to have features
