16 GB DDR4-2400 ECC registered RDIMM matching Dell 370-ADGL with CL15 latency and 1.2 V operation
This 288-pin DDR4 module provides 16GB of registered memory with error-correcting code for server platforms. It operates at 2400 MT/s (PC4-19200) with a CAS latency of 15 at 1.20V. The dual-rank 2Rx8 organisation uses major-brand DRAM chips and matches Dell part 370-ADGL for drop-in compatibility.
Administrators expanding Dell PowerEdge or other registered-DIMM platforms can use this module to increase virtual-machine density and reduce paging. Systems that require unbuffered UDIMMs, load-reduced LRDIMMs, or non-ECC memory cannot use this part. Buyers needing higher speeds, larger densities, or different rank configurations should look at other modules.
The registered buffer and on-die ECC protect data integrity in multi-DIMM channels, while the dual-rank 2Rx8 layout balances capacity and signal loading. Verify that your server board supports registered DDR4-2400 RDIMMs and the 2Rx8 rank structure before purchase, as unbuffered or single-rank-only platforms will not post with this module.
