Asrock Rack X570D4U AM4 mATX-emolevy

Bought this gem for a NAS build after i found the B550 chipset doesn't support more than 3 drives with a m.2 drive installed. Now i've got a beast of a NAS/media server with 8+ drives.

I do not give 5 stars because I had an issue with RAID tool from the MB. Contacted Tech Support: they are skilled but my various tests were not conclusive.

It does the job Installed 16gb (8x2) 3200ghz Corsair ram on it and it is not stable when loading the xmp to get the advertised speed on the ram. It keep reverting back to 2133 ghz Also cpu overclocking is not stable beyond 4300ghz on R7 3800x Sometimes it doesn’t even load the first screen and I have to manually flush the bios to redo the UEFI configuration all over again I would add more 100$ and get a more reliable one instead of wasting 160$ on this

First AMD build and first Asrock board. No problems with build, used setting in BIOS to format a new MVMe and install windows from a USB stick. System is very quiet and fast. Ram is running at the rated 3466mhz. Very happy with this board.

Does the job. (Added this to get by the stupid character limit).
