Server 32GB DDR4 2933MHz PC4-23400 ECC UDIMM 2Rx8 Dual Rank 1.2V ECC Unbuffered DIMM 288-Pin Server & Workstation RAM Memory Upgrade Module (A-Tech Enterprise Series)

A-Tech price is good and this (2x32GB 2R8 UDIMM) one is compatible with my HPE Proliant Gen 10 Plus v2 desktop server (2 DIMM slots, max out at 64GB). It would have been better if A-Tech lists the exact part number on its website's compatibility list so that matching it to Amazon would be easier. The upgrade takes minutes.

Manufacturer refuses to replace memory due to damage that's not my fault

The modules I received were black instead of green like the picture showed, but this is better for me anyways. I bought these to replace some failing RAM and figured I would add ECC support since my CPU and mobo support it. I have a Ryzen 3800X with the Asrock x470 Gaming ITX/ac. These sticks work perfectly fine at 3200MHz, but I did have to clear my CMOS to get my machine to POST. I tested them fully with memtest86+ v7.0 without any issues. Highly recommend!

I've read that the HP Proliant Microserver Gen 10 Plus could work with 64GB of memory even though HP state that only 32GB or less are supported. This 64GB memory does work. I ran Memtest386 and it passed. The computer shows 64GB of memory is installed. I bought two sets of this memory for the two HP Microservers that I have that run Proxmox. Memory was my limitation and this solves that for me.

Update: Called A-tech and had an RMA filed, they sent out the new ram and a return label for the old ram. I bought this ram for its uecc support since I was planning to use it in a ryzen homelab build. After 6 months, UECC reported an error as expected and corrected it. However, this was an idle system with a live-installer shell and it’s only going to get worse over time once it becomes a virtual host. I confirmed the error with memtest86, which showed ecc was supported and testing each stick and slot. Memtest86+ didn’t catch anything this time but I use both since sometimes one reports something the other missed. I am 6 months past my return so I hope the RMA process is easy. I’m not sure if the issue was always there or if it was recent since I didn’t have time until now to work on this setup and replaced a gigabyte motherboard with asus to get better uecc support since it can correct and report up to the kernel.

This is really good memory. I purchased 4x32GB and I’m very surprised how rock solid these are. They are Samsung die and all passed 24 hours of Memtest without a single error. This Atech memory kits are much better quality than a better known memory brand which I had to return because half of the modules were showing Memtest errors. Highly recommend these.

Memory that does exactly as advertised. I've purchased two of these kits now for my TrueNAS Scale project and have had no issues with the kits.

Had these installed in our new server tower at work, worked perfectly, easy to installl.

Works fine in my cheep ass ASRock mobo running Truenas core. Truenas shows memory as ECC so I'm happy
