Kingston Server Premier 32GB 4800MT/s DDR5 ECC CL40 DIMM 2Rx8 Hynix M Server Memory - KSM48E40BD8KM-32HM

Works great in Asrock Rack AMD server B650 server boards

ECC is detected. Passes memtest x86.Overclockable to 5600 without increasing voltage. 6000 at 1.25v with ECC on. 36-38-38-76Memory temp is around 60C under stress.

Using 4 sticks of this at 3200Mhz for 64GB of ram in a Asus Prime X570-Pro with a Ryzen 3900x and Proxmox (linux) for an OS. Ran Memtest for 8+ hours with no errors. I did specifically enable ECC in the BIOS. Proxmox reports it is using ECC using the dmidecode command.root@pve:~# dmidecode -t memory | grep -i ECC Error Correction Type: Multi-bit ECCThe amazon listing is light on the details but this ram is Unbuffered, 288pin, 1.2v, with a timing of 22-22-22, and dual rank (2Rx8) as expected.

Bought 12 of these for 3 AM5 based servers (4 DIMMS in each computer). With DDR5 you have to slow down the memory speed to run with 4 sticks. 2 servers could post at 3600 but one did not. We set all 3 servers to 3200 to make it post across the board. Otherwise memtest86 reported no issues with the RAM.

thanks

I ordered a pair of these ram sticks, but only one worked.Just put it in for replacement, so will have to update when it arrives.Two stars just for the hassle so far, the one stick is working great.

Using in tandem with W680m motherboard.0 issues and very reliable.The only issue is that the price is insane. I will be waiting for the prices to drop to buy more.

ECC functionality has been successfully tested (enabled) under Ubuntu 20.04LTS and Windows 11 with two ram stick on a ASUS x470-f strix motherboard with a 2700X CPU.

This is the only ddr5 ecc ram supported by my motherboard and so so far it is rock solid. A bit on the pricy side but works well

This Kingston RAM-stick is barely more expensive (when I purchased it) than the other 16GB 3200MT/s RAM offered on the market, although the prices have shifted quite a lot ever since the introduction of AMD Ryzen 7000 series and their AM5 platform, along with DDR5 RAM, Intel Core 13th Gen and so on.Even though it has a CAS Latency of 22 compared to most "gamer PC" RAM sticks that have CL16, you do not need to enable the unstable DOCP in your motherboard to ensure this stick gets clocked at 3200MT/s RAM, for other sticks I have used such as Corsair Vengeance, DOCP had to be enabled with specific DRAM stats configured manually to prevent system instability and BSODs, the CL22 is barely noticeable in games as long you have good quality hardware.+ Multi-bit ECC RAM (PowerShell "wmic memphysical get memoryerrorcorrection" yields value 6)+ CL22 not exactly noticeable in real-world performance+ Normal profile DDR4 288-pin form factor just like most other DDR4 RAM sticks, may only conflict with large CPU coolers (some Noctua coolers tend to like claiming a lot of space, forcing usage of low profile RAM) but this is not unique to these RAM sticks.+ Works on "consumer" desktops using AMD's AM4 platform, as long your motherboard supports it, due to the fact that it's Unbuffered ECC RAM+ Inexpensive 3200MT/s clocked RAM+ Plug & Play on ECC Supporting Motherboard if using AM4 AMD CPU (auto-3200MT/s, no DOCP needed)- The fact it's Unbuffered ECC RAM can also be a negative point, this makes it not recommended for actual server racks (assuming you use an actual server motherboard like Supermicro, if your server is more like a regular desktop, this may not apply)- It has no heatsink unlike typical gamer RAM sticks since ECC RAM is not really targeted at gamers or regular desktop users.* It's 1x16, not 2x8 GB of RAM, you could order two of these to use 32GB in dual-channel setup.* DDR4 288-pin DIMM 3200MT/s 1x16GB 1.2V Multi-bit ECC CL22 tRCD22 tRP22 tRAS52 tRC74 CR1T FSB:DRAM 1:16 SK HynixTested hardware combinations* CPU AMD Ryzen 3 3100 Matisse 4C/8T and AMD Ryzen 5 5600X Vermeer 6C/12T (AM4, unofficially supports ECC)* MOBO ASUS TUF Gaming B550M Plus Wi-Fi (mATX, AM4, supporting ECC) BIOS 2806* Graphics MSI NVIDIA GTX 1050 Ti 4GB OC and NVIDIA RTX 3070 FEGraphics only included for information related to gaming performance in combination with ECC RAM.Other specs omitted as they are not relevant.
