A 16 GB DDR5-4800 ECC registered RDIMM with 1Rx8 organisation, built to match Dell part 370-AGZO for server upgrades
This 16GB DDR5-4800 ECC registered RDIMM is built for servers that require error-correcting memory. It matches Dell part number 370-AGZO for direct replacement in compatible systems. The module uses a 1Rx8 organisation with major-brand components. It is intended for administrators who need validated compatibility without OEM pricing.
Standard DDR5 registered DIMMs operate within JEDEC voltage limits for the 4800 MT/s data rate. Error-correction circuitry adds minimal overhead compared with unbuffered modules. The registered buffer reduces electrical load on the memory controller, helping signal integrity at speed. No active cooling is required beyond normal server airflow.
A lifetime warranty covers the module for as long as it remains in service. Every order ships with identically matched modules to maintain uniform timing across channels. Third-party validation is designed to preserve the original server warranty. Buyers who need non-ECC or unbuffered memory for workstation boards cannot use this module.

Align the notch with the DDR5 slot key, press firmly until both ejector clips click shut, then verify the module is fully seated by checking the clips are locked on both sides; the step often missed is confirming both clips engage completely.
No routine maintenance is required; the module is covered by a lifetime warranty, so replacement would only occur if a hardware fault develops during normal server operation.
The registered buffer and ECC logic add a small latency overhead, so the first limit under sustained use is typically memory-controller throughput rather than the module's rated 4800 MT/s speed.
