Server memory kit

This kit provides 64GB of DDR4 ECC unbuffered RDIMM memory across four 16GB modules. It is designed for administrators upgrading compatible HP ProLiant ML30 or DL20 servers that require registered DIMM form factors.

Verify server model and slot count

Confirm the target system is an HP ProLiant ML30 G9, ML30 G10, DL20 G9, DL20 G10 or MicroServer G10. Ensure four DIMM slots are free and that the platform accepts 288-pin DDR4 PC4-21300 modules at 2666MHz with CL19 latency.

Fills four slots for maximum capacity

Populating all available channels delivers the full 64GB without mixing module sizes. The ECC unbuffered design maintains data integrity for server workloads while leaving no spare slots for future expansion.
