Searching for ECC DDR4 RAM for the AMD EPYC processor? Providentially, we have compiled a list of the best AMD EPYC ECC DDR4 RAM (Buffered) currently available on the market. AMD EPYC is a fantastic server processor that distinctively offer more I/O throughput for cloud data centers.
AMD support has already confirmed that registered ECC memory support is only for EPYC CPU’s. See their email below:
In case if you are wondering what ECC DDR4 RAM is, then let me give you a brief intro about it. So ECC memory or Error-Correcting Code Memory is a type of DIMM which has a 9th memory module for storing parity data. This kind of memory detects and correct the most common kinds of internal data corruption (if any). This memory is beneficial for servers where the data is very crucial, and any loss of data might cause significant problems. If the data corruption can’t be tolerated at any cost, you must switch to the ECC RAM.

ECC RAM are two types unbuffered ECC RAM and registered ECC RAM. The significant difference between the two is how the commands are sent from controller to the memory module. In unbuffered memory, configurations, the ECC-commands go directly from the controller to the memory module. While in Registered ECC memory configurations, the controls are sent first to the memory bank’s registers and then forwarded to the memory modules.
That’s enough about the ECC RAM, now let’s move on to the list of best ECC DDR4 RAM for AMD EPYC server processor.

The first RAM on our list is Kingston Technology 8 GB DDR4 ECC Registered server memory for the AMD EPYC CPU. It is a 288-pin Registered DIMM @2133 MHz backed by a lifetime warranty from Kingston. If you need around 8 GB of RAM for your server, this one would be the most suitable option for your system.
As we already stated that we have mainly two types of ECC DDR4 RAM, registered and unbuffered. So starting the list of best ECC DDR4 Registered RAM for AMD EPYC CPU. Get more speed, and bandwidth with the Crucial 32 GB Kit ECC registered RAM. It is perfect for networking, cloud computing, HPC, and Big Data. DDR4 memory has twice speed and capacity as compared to the DDR3 RAM. Power consumption is an important factor while building a PC. Crucial 32 GB DDR4 ECC RAM kit is power efficient too and consumes 40% less power as compared to the DDR3 technology and operated at 1.2V.
Above Kingston, 32 GB memory kit is a great option for the AMD EPYC CPU, but it has two memory modules of 16 GB. If you are looking for a single 32 GB ECC registered memory module, Samsung A-tech module is for you. It comes with lifetime warranty and technical support at no additional cost. Rest of the specifications are standard as of the rest of the Registered ECC RAM.
If your server system is big and you are looking for 64GB ECC registered DDR4 RAM for the AMD EPYC processor, Timetec Hynix 64 GB ECC RAM kit is the best suitable option for you. It is a 2R x 4 CL15 dual rank server memory module that works with 1.2 V. It is compatible with plenty of server motherboards that could find out on their site.
If 128 GB memory is your requirement, we have Kingston 128 GB Kit (4 x 32 GB). No doubt, Kingston is the industry in the PC memory. This kit consists of four 32 GB modules of 2133MHz DDR4 memory. The rest of the specifications are standard.
All the above server memory are Registered, now we listed few best unbuffered ECC RAMs for the AMD EPYC CPU. Unbuffered memory modules are a bit cheaper at the sacrifice of a performance by a slight margin. If you have budgetary restrictions, it is not a bad idea to choose the unbuffered ECC RAM. The first best 8 GB ECC RAM is from Kingston.
It delivers unmatched performance and reliability at a competitive price. Its speed starts at 2400 MHz, and 32% increases in memory bandwidth. As it is a DDR4 memory, the power consumption is reduced by 40% as compared to the DDR3. It is CL17 unbuffered DIMM that makes everything on your computer faster.
For 16 GB, we have Crucial Single 288-pin unbuffered ECC DDR4 RAM. It is a dual-ranked x8 based Unbuffered DIMM for the server CPUs that provides faster burst access speed. Memory upgrades are one of the easiest and affordable ways to increase the performance of any system. It operates at speeds of up to 2400MT/s and has a CL17 latency.
The last unbuffered ECC DDR4 memory for AMD EPYC CPU is 32 GB (16 GB x 2). It is a dual rank x8 based unbuffered 288-pin DIMM. It is an easy cure for a slow computer, just add more memory and load programs faster than ever. It conforms to the industry standards for DDR4 UDIMM layout of 288 pins and is compatible with systems that use DDR4 2133MT/s UDIMM memory. The rest of the specifications are mostly the same as the above unbuffered ECC DDR4 RAM.
