AMD StoreMI Technology

A powerful tool that combines the speed of your SSD with the capacity of your hard disk into a single, fast, easy-to-manage drive. SSDs are fast, but expensive, and offer minimal capacity. Mechanical hard drives boast large capacity for a low price, but are much slower than an SSD. AMD StoreMI technology "combines" these two types of storage into a single drive and automatically moves the data you access the most to the SSD, so you get the best of both worlds: SSD responsiveness, and mechanical hard disk capacity. You can also use up to 2GB of RAM as a last-level cache for ultra-fast data.

B450M
Dual M.2 For SSD

Horrible product

Pros: plenty of USB ports, layout isn't too cramped so it's easy to make the connections.

Cons: Does not play nice with others. I have had constant memeory managment issues with this computer build even though all drivers have been updated: I've tried 3 different sets and two different brands of RAM and two different graphics cards. Oh, by the way there isn't actually onboard graphics on this card. You have to have a separate Graphics card plugged into the board in order to get video of any sort. The listed specifications are a bit misleading. No big deal since I had one but for the less informed it does sound like you would be good to go without a separate Graphics card.

Other Thoughts: No! I've built several compurters and have never had this many problems with a build. I have done all the trouble shooting that can be done and the problem has to be with the board everything else has been swapped out or changed. I'm a couple months into this fiasco and it is still not resolved. WIth memory mangement errors you would suspect the RAM or drivers, etc not the motherboard itself. I am not happy at all with this board.

Manufacturer Response:
Dear Valued ASRock Customer,

Thank you for purchase and review.
For the memory/RAM, mainboard works most of the memory on the market.
However, we provide the memory QVL list following link for reference.
Memory QVL for Pinnacle Ridge CPU Link: https://www.asrock.com/mb/AMD/B450M-HDV/index.us.asp#MemoryPR

For the onboard video, Please assure that using CPU has built-in APU or requires external/discrete GPU to post.
Please visit specification link below under Graphic section (*Actual support may vary by CPU) to verify.

Cons: None so far.

Stop using one-tabbed RAM slots, ASrock...

Pros: Once RAM is magically inserted properly (you won't know by any means other than successful POST), it works.

Cons: One-sided (tabbed) RAM slots save what...five cents, per slot? Can this possibly lead to more profit than dealing with "DOA" boards?

Other Thoughts: ASrock seems to have a lot of "DOA" reviews. I would venture to guess that 99% of them are RAM-related. Use two-tabbed (two-sided) RAM slots like other manufacturers, Asrock, and you won't have so many "DOA" boards being returned to you.

Decent motherboard but major issues with overclocking and not very tough

Pros: - Small size which was great for MY purposes (smaller than most mATX boards probably since it only has two RAM slots
- Great low price
- Came with helpful accessories
- The cons to it (that affected me) might not be a factor with most people
- Supports Ryzen 2nd gen processors
- Supports m.2 ssd

Cons: - Trouble giving video signal
- I couldn't overclock my 3600mhz ram to 3600mhz, it went to 2133 automatically, when overclocked the PC restarts
- The video signal worked after adjusting its' positioning on my customized case which kinda scared me
- There is a bottom tray under the CPU that can fall out when installing/removing/adjusting the CPU fan

Other Thoughts: System:
Ryzen 3 2200g, I plan to upgrade once AMD's 7nm process comes out so I went this low end one.
G.Skill 3600mhz 1 x 8GB stick of RAM
HP ex920

Please READ:
YOUR RAM might overclock easily with an Intel CPU because the XMP profile may not just work with AMD, or maybe it was the power supply which is only 250w, or my own inexperience.

pretty good

Pros: Neutral color scheme
Performance / dollars spent
Does most things well

Cons: One sided ram tabs
I/O plate is super generic

Other Thoughts: This board does everything you could want it to, given the cost. I have a 2200g, WD 250 gb nvme, WD blue SATA 3 1tb HDD, an rx580, and a 550 watt psu. Everything works great after initial set up.

Setting the ram into the slots was less convenient than I imagined, and I did have to re-install the sticks to get the system stable. The slots are tough to work ram into and the single tab lockdown design doesn’t help the build process.

Other than that, it is a good board. Worth the price I got it at.

Good motherboard for budget build.

Pros: Worked out of the box. Installed ryzen 3 2200G and is compatible with G.Skill value series 8gb 2666mhz ram (F4-2666C19S-8GNT)

Cons: The box it came in seemed like it was opened before. The box wasn't wrapped and only came with 2 Sata cables and nothing else.
4 stars because of this otherwise good mobo.

Great starter motherboard

Pros: -M.2 Support
-VRM Heatsinks
-Good layout, I appreciate that the GPU is under the M.2 Slot rather than above it
-Plenty of support for fans on the motherboard

Cons: -Issue where USB ports randomly disable themselves for a few seconds
-Would have preferred dual-tabbed ram-slots.
