16GB DDR5-5600 ECC UDIMM for Hynix replacement

This 16GB DDR5 module runs at 5600MHz with CAS latency 40 and 1.10V operation. It is built as an unbuffered ECC UDIMM with a 1Rx8 rank layout using major-brand DRAM ICs. The part serves as a direct replacement for Hynix HMCG78AGBEA and HMCG78AGBEA081N server memory.

288-pin DDR5 form factor with no heat spreader

The 288-pin DDR5 DIMM fits standard unbuffered ECC slots in compatible servers and workstations. Without a heat spreader the module keeps a low profile for dense chassis or restricted airflow paths. Major-brand chipset components and factory testing target dependable operation under sustained workloads.

Upgrade from lower-capacity

Adding this 16GB stick increases total memory bandwidth at 5600MHz and extends ECC protection to larger datasets. The jump is worthwhile when current modules limit multitasking throughput or when a qualified Hynix replacement is required for validated platform support. Buyers needing registered RDIMM modules or higher-density ranks should verify platform requirements before purchase.

Questions about this item

Does DDR5 5600 (PC5-44800) run at 5600 MT/s or drop to a lower speed?

The module is rated for DDR5 5600 MT/s (PC5-44800); actual speed depends on the platform's memory controller and BIOS configuration.

Will this 288-pin DDR5 UDIMM fit my server's DIMM slots?

It uses the standard 288-pin DDR5 UDIMM form factor; verify your system accepts unbuffered ECC DDR5 before installing.

How do I seat the module correctly and avoid the common mistake?

Align the off-centre notch with the slot key, press straight down until both retention clips click, and check your manual for the correct channel population order.
