KingstonKSM26ED8/16ME Server Premier - DDR4-16 GB - DIMM 288-pin - 2666 MHz / PC4-21300 - CL19-1.2 V - unbuffered - ECC

No RGB, no glitter, no junk. In a world, where you cannot rely on the Samsung or Crucial RAM from the QVL list to be available or rather, available at a reasonable price point, this stick brings the unbuffered, ECC to your AM4 board. The great irony of this RAM is that it has better reports of compatibility than the equivalent Crucial offerings despite the fact that it is a Micron DRAM OEM. It will not break any speed or density records, but it brings stable ECC memory to AM4 builds.I have personally used this RAM in builds with Asrock Taichi X370, X470D4U, X470D4U2-2T, and X399D8A-2T. Memtest on all installed modules which have to number close to 20 (not all bought for personal use or on Amazon), no lemons. Plug them in, and stop chasing the Samsung B-die dragon or overpriced Crucials.

I used this memory in a recent AMD Linux PC build that is my home router/firewall as well as doing 24/7 video recording in a containerized version of Frigate. As it is doing more than just basic file serving I wanted to ensure maximum reliability. This RAM runs fine in an ASRock A520M motherboard with Ryzen 5 Pro 4650GE. Error correction works perfectly, with the RAM successfully completing error injection tests in MemTest86+. One thing, the motherboard auto-selected 3200MHz operation by default. I had to manually change it to 2666MHz. Overall I recommend it highly.

I am running on a Asrock Taichi Ultimate x470 motherbooard (Using 10GBps LAN) with a AMD Ryzen r5 2600. I have 36TB total drive space, it is comforting to know I have such great ECC ram that is working to protect my data. The computer I built is very quiet something you will not find for most servers. I set it up to be low power, quiet, 6 core-12 threads. This ram is making it possible to have no data errors in storage and it runs at 1.2volts. I literally just set installed into the ram slots and forgot it. I do not use it for gaming so I did not give any stars there. I also use as a home lab machine with VMs. I have verified this memory and it shows up as fully functioning ECC memory. I am completely satisfied and have absolutely no complaints.

Got 64GB for my Asrock Rack x470U motherboard and AMD 2700. This works great for a server build! I'm using this for my VM's for development/security testing. Would recommend to anyone looking for DDR4 Unbuffered ECC ram at a good price.

Sellers Perfect Stock and Express Goods both provided sticks of ram with manufacture dates within the last 6 months. No defective sticks after many memtest passes. All running at advertised clock and timings. ECC verified.For the value, if this is going in a server, you will not beat this. Rest assured, the ECC functionality performs precisely as expected, and no tangible benefit is obtained from the sticks at almost double the price.These do not include any thermal dispersion mechanisms at all but the thermals on them aren't too hot.These are dual rank.

We've been using Kingston RAM (ECC and non-ECC) for decades in scores of servers... yikes sounds like a long time. It always works, including a recent build using their 2TB - M.2 flavor.

With a Ryzen5-3600, this motherboard is running these ECC UDIMMs. You can even set the patrol scrub interval in the BIOS. These Kingstons came right up, running 2666MT/s in a fully-loaded arrangement. Been hitting the whole system with stressapptest for 15mins at a time, every so many hours. So far, no CEs (Correctable Errors) or UCEs (Un-Correctable Errors) according to edac-utils.

I got this for my Ryzen 5 3400GE Pro. It's excellent ram if you need ecc for a small home server. Recommended as compatible in my Asus motherboard manual. Even confirmed the ECC function was working and reporting errors properly in Debian Linux after I overclocked it a little to generate errors.
