  • 32 GB capacity with two 16 GB modules
  • 2666 MHz DDR4 speed rated at PC4-21300
  • ECC unbuffered RDIMM for server reliability
  • CL 19 CAS latency for responsive timing
  • 288-pin form factor fits compatible HP ProLiant servers

32 GB dual-channel kit for DDR4 servers

This Samsung kit provides 32 GB of DDR4 memory across two 16 GB RDIMMs. The modules run at 2666 MHz with a CAS latency of 19 and carry ECC unbuffered error correction. They are built for HP ProLiant ML30 G9, ML30 G10, DL20 G9, DL20 G10 and MicroServer G10 platforms.

Steady throughput under continuous server workloads

The PC4-21300 rating reflects sustained bandwidth rather than burst speed. ECC unbuffered operation corrects single-bit errors on the fly without adding registered latency. Dual-rank 16 GB density keeps each channel populated for consistent throughput during long compute or virtualisation tasks.

Verify 288-pin RDIMM slots

Confirm the motherboard accepts DDR4 RDIMMs in a 288-pin form factor and enables ECC unbuffered mode. Check that the system BIOS recognises 16 GB per module at 2666 MHz. Ensure the server model matches the listed HP ProLiant or MicroServer series before ordering.

Questions about this item

How much power does the 2666MHz DDR4 RDIMM kit draw under continuous load?

Standard DDR4 RDIMM modules at this speed typically operate at 1.2 V, so the pair draws only a few watts even when fully utilised all day.

What motherboard slot and memory type must my system provide for these 288-pin modules?

You need a server or workstation board with DDR4 RDIMM slots that accept unbuffered ECC memory.

Will these CL19 sticks run reliably in an older HP ProLiant ML30 G9 alongside existing memory?

Yes, the kit is validated for the ML30 G9 and other listed ProLiant models, so it will operate at the platform's supported speed when mixed with compatible DIMMs.
