Server-Ready DDR4 Module

This Silicon Power SP016GIRFD320B00 is a 16GB registered DDR4 DIMM built for server platforms. It operates at 3200 MT/s with a CL22 latency profile and runs at the standard 1.20V. The 288-pin module uses a dual-rank 2Rx8 organisation based on Value Grade Samsung C die.

Suited for Registered Memory Slots Only

The module is designed for systems that require registered memory with on-board parity registers. It will not function in desktop or laptop boards that accept only unbuffered DIMMs. Builders needing unbuffered memory or a different capacity should select an alternative part.

Registered Buffer Is the Deciding Factor

The single specification that determines compatibility is the registered buffer. Only motherboards and processors qualified for registered DDR4 can use this DIMM. Verify the platform documentation before purchase.

Questions about this item

How much power does the 1.20 V DDR4 3200 registered module draw under sustained load?

The module operates at the standard DDR4 voltage of 1.20 V. Registered DIMMs add a small register overhead, so power draw is slightly higher than an unbuffered equivalent at the same speed and capacity.

What motherboard feature is required to use this 288-pin registered DDR4 3200 DIMM?

The motherboard must provide a DDR4 RDIMM slot with support for registered memory. Standard consumer boards that accept only unbuffered UDIMMs will not work with this module.

Can this CL22 2Rx8 registered DDR4 3200 module run in a system that already has slower registered DDR4 installed?

Yes. The memory controller will run all installed registered DIMMs at the lowest common speed and tightest common timings, so faster modules simply down-clock to match the existing kit.
