B650D4U-2L2T/BCM Micro-ATX Server Motherboard Single Socket AMD Ryzen 7000 Series Processors (LGA 1718) B650E PCIe 5.0 Dual 10G LAN

My board shipped with the launch bios (1.14) and posted no problem with random DDR5 memory I had laying around that wasn't on the QVL along with a 7700x. Initial post took quite a bit but every subsequent one was far shorter.IPMI worked perfectly out the box which I used to update the bios and BMC. Since then its been running for days without issue and offers a huge convenience gain over a traditional consumer motherboard for my home server. I no longer have to pull out a monitor/keyboard/mouse anytime I have to tinker and can do so at my convenience anywhere.Just a tip, if you have compatibility or post code issues, pull the CMOS battery. It worked to make a friends board post that wouldn't initially due to a memory debug code.

I am writing this review to express my profound disappointment with the ASRock B650D4U-2L2T/BCM Micro-ATX AM5 DDR5 Motherboard. Despite its promising specifications and compatibility claims, my experience with this product has been far from satisfactory.I initially procured this motherboard with the intent to utilize Micron's 32GB memory modules, which were purportedly compatible with this device. However, regardless of my efforts, these memory modules failed to function as expected on not just one, but two of these motherboards that I had purchased. The motherboards consistently returned error codes 0xC5 and 0x70, indicative of memory-related issues.In an attempt to troubleshoot these issues, I even invested in an additional CPU. Regrettably, this did not rectify the situation. The motherboard continued to exhibit the same errors, rendering my efforts and additional investment fruitless.Furthermore, the BIOS on this motherboard is alarmingly sluggish, a trait that significantly detracts from the overall user experience. The booting process, in particular, is protracted to the extent of taking hours. This severely hampers productivity and falls short of the performance standards one would expect from a product in this category.In conclusion, I am unable to endorse the ASRock B650D4U-2L2T/BCM Micro-ATX AM5 DDR5 Motherboard based on my experiences. Despite its promising specifications, the product fails to deliver in terms of compatibility and performance, and has thus proven to be a considerable disappointment.Please consider this review as constructive criticism. I hope that these issues can be addressed and rectified in future iterations of this product.UPDATE:ordered replcement boards: both deliveries failed

Its a well provisioned workstation mobo, but the bios is poorly made. it wont talk with most boot loaders. I had to install the OS on a separate machine, then physically move the hard drive to this one. it worked but the bios is terrible and ASRock feels no obligation to fix or care about it.

The IPMI function is broken. One board shows the IPMI UI in BIOS but cannot connect to the web UI. Another board doesn't even have the IPMI setting (A.K.A "server mgr" page). Unless you don't need the IPMI support, I don't suggest buying this motherboard unless ASRock fixed their BIOS.

BCM/IPMI seems to work fine - but reports no info for CPU or memory. All voltages reported as correct. Using 7950X CPU (supported) and two different brands of memory from ASRock's QVL (supported). Startup always fails to complete with error code 99. BIOS doesn't start. ASRock simply responds to support requests with "contact your vendor".My guess is that ASRock needs to upgrade their BCM and BIOS to provide better support for CPU and memory options. But this particular motherboard may simply be bad.The BCM is slow, as reported by others, doubling or tripling expected workstation boot times, but this is not too different from other server motherboards. They tend to be annoyingly slow to start up.
