I changed some RAM in my main PC and moved it to the NAS. The stick is a 4x16 GB Corsair Vengeance CMK32GX5M2B52000C40. The motherboard is an ASUS PRIME B650M-A AX II with an AMD 8600G chipset. It can handle up to 192 GB of RAM. The part isn’t listed in the supported memory database, but I thought it should still work at JEDEC standards. It hasn’t shown any output for about 20 minutes now. I’m wondering how long to wait before giving up on this RAM type, and why DDR5 seems so tricky—maybe I was just not paying attention before it failed? Perhaps it was just my ignorance, but it seemed to work fine with DDR4.

Working with 4 RAM sticks on AM5 systems can be challenging and sometimes unfeasible, even at regular speeds. Consider using 2 sticks to test booting. Spend about 5 minutes with the early BIOS settings. Upgrade to a newer BIOS in 20 seconds to 2 minutes.

It's quick and puts pressure on the CPU memory controller. As @Hinjima pointed out, AM5 doesn't support four sticks. To address your main concern, I begin to question if something was off around the five-minute point.

Few minutes or little more, at least for first memory training, the next trainings shouldn't take minutes, maybe just one max. If subsequent memory trainings take long, BIOS update could fix that. Sometimes though it's just matter of luck and certain RAM+MB combinations can give you long MT times. There's even an option to turn off memory training. Also, booting with 4 DDR5 sticks that aren't running at "base" speed is already kind of an accomplishment. 6000Mhz CL30 the sweetspot, is even harder to run on 4, same or worse with speeds above that. Doable of course, doesn't have to be guaranteed fail, 4 DDR5 sticks can work, and sometimes even at XMP/EXPO speeds - or that but after little tweaks.

I had trouble getting these 4 sticks to function well on my 12700k, which is why I upgraded. On that site I bought a faster 2x32 GB stick to improve stability and speed. It loaded right away with two sticks, still an upgrade for my NAS. Since this is early generation RAM and I can't sell it cheaply, I'm taking what I can get.

The AM5 system shared its immediate update with two sticks, which isn't unexpected. AM5's memory controller constraints make it nearly unfeasible to use four sticks effectively. This has led us to adopt 2x24GB and 2x48GB DDR5 configurations to achieve higher RAM capacity with just two sticks. This approach could be worth considering in the future if you still desire more storage while maintaining stability. Upgrading the BIOS is also strongly advised, as newer versions improve RAM compatibility and reliability. If your BIOS is outdated, consider updating it and testing with four sticks again. Don't expect miracles, but I've personally experienced success.

About 3-5 minutes... I just glance at my phone for a moment. If the LED changes color, it means you're either moving too fast or the system suggests you should run half of them. I believe it's best to keep each group in its own channel. For instance, using serial numbers—first two slots for the first set, then the next two for the second.

I started up everything correctly after resetting the BIOS. I’m still planning a memtest to verify performance and make some adjustments. It ran at the same rates as the original sticks—CL30/6000 versus CL40/5400. The RAM was noticeably slower, but the rest of my NAS setup was just 2x8 GB, which shouldn’t be a big issue for my needs.
