Pros: - Crucial website showed it should work with x470 motherboards - Overclocks to DDR4-3200 (not that anyone should be doing that normally) - The overclock frequency is not bad considering the stock frequency and timings - It works really well with Zen+ and Zen2 CPU

Cons: - Not faster (would like stock DDR4-3200 or DDR4-3600 speeds) as Zen2/Zen3 need higher frequency RAM to get the best processing value from the CPU. - Difficult or impossible to find this RAM on Crucial website searches

Overall Review: (review has been updated 2020-07-03) This ram seemed to operate correctly (recognized by Windows 10 with multi-bit correction) but initially my ASRock x470 Master SLI/ac motherboard didn't like warm reboot with this ram. A BIOS update was required. (Update 10/22/2019) After a few days passed after submitting a ticket with ASRock they replied and I was able to successfully test a beta BIOS. The initial recognition after installing the ram is fixed along with the warm reboot and boot loop problems are fixed when using this RAM. Working well. Thank you ASRock!

Pros: - works great - works with Synology NAS using generic driver

Cons: - constantly resets in the cold/rain and becomes unusable - not officially supported by Synology NAS yet

Overall Review: - will post an updated review after some usage ( updated 9/3 ) All my problems started after upgrading the firmware after I bought it. This broke compatibility with Synology DS418j NAS. The last winter was a total failure as it would constantly reset and never become operational in the cold. This past summer it was also resetting in the rain (heavy moisture) and becomes unusable but in the dry heat it seems to work. There seems to be a new firmware update now v3.1.0.956_22041511_v1.0.0.30 will see if that works to help fix problems otherwise I think I got a defective unit.

Pros: - 16GB

Cons: - not ECC

Overall Review: - It's SODIMM ram that works.

Pros: - You can do a lot in this ITX case

Cons: - Top fan mounts will sag over time. Cooler Master should just have stuck with standard mounting screws - Top I/O ports seem cheaply made and my USB port broke (contact pins folded in).

Overall Review: - The biggest problem I have is my top USB port broke after inserting a USB stick. The replacement for the front I/O is really expensive to the point I might as well just leave it broken forever. It would be great if Cooler Master could give me a replacement front I/O module. - Cannot top mount an AIO or custom water cooling radiator

Pros: - Mine was DDR4-3200 Micron ECC

Cons: - Default timings are not that great.

Overall Review: - Change dram voltage to 1.35v to make this DDR4-3200 CL22 ram kit potentially a DDR4-3200 CL16 ram kit (obviously you must test and setup timings yourself)

Pros: - I got the rev 1.06 board that fixes the placement of the internal USBC header - 3 NVMe slots - Clear CMOS button - Power and reset buttons on board - BIOS flashback - RGB works well - Works with DDR4 ECC RAM

Cons: - Armor makes it impossible to install NVMe drives without taking out the GPU. - As with many X570 boards with the chipset fan large GPU's will obstruct the fan cooling

Overall Review: - If you get this board you must put a 5950x into it! - VRM's are great quality - Use a water cooled GPU so the chipset fan can get some cool air when needed
