Registered ECC Only: This module is Registered (Buffered) ECC, not Unbuffered. It is not compatible with standard desktop PCs or systems requiring UDIMM or non-ECC RAM.
CPU & Chipset Dependent: To achieve the full 3200 MT/s speed, your system must support DDR4-3200 RDIMM and be equipped with a compatible Intel Xeon Scalable Gen3or AMD EPYC 7002/7003processor. Older platforms may default to lower speeds (e.g., 2933 or 2666).
Mixing Brands: You can mix brands if the specs match (32GB, 2Rx4, ECC RDIMM, 3200MT/s). The system will clock all memory down to the speed and timings of the slowest installed module.
Server-Qualified: These modules pass strict validation for uptime-critical environments and are often used in datacenter deployments, virtualization hosts, and enterprise applications.
Installation Tip: Always populate DIMMs in matched pairs and follow your system’s memory population guidelines for channel balancing and optimal performance. Use ESD-safe precautions when handling memory.
Backward Compatibility: Fully backward compatible with systems supporting lower-speed DDR4 ECC RDIMMs (such as DDR4-2933 or DDR4-2666). The module will auto-negotiate to the maximum supported speed.
Check BIOS/UEFI: After installation, verify the memory is recognized properly in BIOS/UEFI. A firmware update may be required in some systems for full 3200 MT/s RDIMM support.
