Finding compatible memory for the Intel Xeon Gold 6126 can be more complicated than simply matching the DDR4 generation and memory speed. This list is based on known configurations using two Xeon Gold 6126 processors and includes Samsung, SK hynix, and Micron ECC registered DIMMs in a range of capacities and speeds. Most of the recorded modules run at 2666 MT/s, while several 2400 MT/s modules are also represented. One notable example is the Micron 36ASF4G72PZ-3G2J3, which is rated for 3200 MT/s but is configured at 2666 MT/s in this platform. The table provides a practical reference for identifying memory part numbers that have been documented in working Xeon Gold 6126 configurations.

The Intel Xeon Gold 6248R is a 24-core server processor with support for DDR4 ECC memory at speeds up to 2933 MT/s. The table below lists RAM modules that have been identified as compatible with systems using two Xeon Gold 6248R processors, including Samsung, SK hynix, and Micron modules across a range of capacities and speeds.

One pattern in the data is that 3200 MT/s memory is commonly configured at 2933 MT/s with this CPU, while 2933 MT/s modules generally operate at their rated speed. There are also examples of 2666, 2400, and 2133 MT/s memory. This makes the list useful when identifying replacement or upgrade memory for existing Xeon Gold 6248R systems, particularly where matching the existing module type, rank, capacity, and operating speed is important.

The Intel Xeon Gold 6240 is a 18-core server processor supporting DDR4 ECC memory at speeds up to 2933 MT/s. This RAM compatibility list brings together memory modules that have been reported as compatible with the Xeon Gold 6240, including Samsung, SK hynix, and Micron modules across a range of capacities, ranks, and rated speeds.

One useful pattern in the data is that some DDR4-3200 modules are shown running at 2933 MT/s when paired with the Xeon Gold 6240. This is expected, as the processor’s supported memory speed is lower than the rated speed of those modules. The list also includes 16 GB, 32 GB and 64 GB RDIMMs, along with some LRDIMM configurations. The configured speed column reflects the actual operating speed reported for each configuration, rather than simply the maximum speed printed on the module.

The RAM listed below represents known-compatible memory modules for systems using the Intel® Xeon® Silver 4114. The processor supports DDR4 ECC memory with a maximum supported memory speed of 2400 MT/s and six memory channels.

A notable pattern is that several compatible DIMMs are rated above 2400 MT/s—particularly 2666 and 3200 MT/s modules—but operate at 2400 MT/s when paired with this CPU. This means higher-rated RAM can be compatible without actually running at its advertised maximum speed.

Key observations
2400 MT/s is the CPU’s supported maximum, explaining the configured speeds in the dataset.

The list includes 4 GB, 8 GB, 16 GB and 32 GB DIMMs.

Most modules are ECC Registered (RDIMM), appropriate for Xeon Scalable server platforms.

Both RDIMM and LRDIMM modules are represented; these should not be assumed interchangeable.

Samsung, SK hynix and Micron are the primary manufacturers represented.

2666 and 3200 MT/s DIMMs are compatible options, but they will be limited to 2400 MT/s on this platform.

The Rated Speed column shows the DIMM’s specification, while Configured Speed shows the speed actually used by the system.

Actual maximum memory capacity and compatible DIMM configurations also depend on the server motherboard and its memory population rules.
