Four green DDR3 DIMMs with black chips and gold contacts

Kingston Technology Corp.

Kingston Technology Corp. KVR16R11S4K4/16 16GB (4 x 4GB) DDR3 1600 ECC Registered server RAM

SKU CH-6Q87-1DQF9 MPN KVR16R11S4K4/16

16 GB registered DDR3-1600 ECC kit in four 4 GB modules at CL11 and 1.50 V

  • Total capacity16 GB (4 × 4 GB)
  • Rated speedDDR3 1600
  • CAS latencyCL11
  • Rated voltage1.5 V
  • Buffer typeRegistered
  • Product type240-Pin DDR3 SDRAM
  • 16 GB total capacity in a matched quad-channel kit
  • ECC registered design detects and corrects single-bit errors
  • DDR3 1600 speed with CL11 latency for responsive server workloads
  • 50 V standard voltage keeps power draw predictable
  • 240-pin DDR3 form factor fits registered DIMM slots

Kit Composition & Purpose

This Kingston ValueRAM kit delivers 16GB of DDR3 server memory across four 4GB registered ECC modules. It is built for system integrators and white-box builders who need JEDEC-compliant DDR3 1600 registered memory with error correction for stable 24/7 operation.

Suitable Builds & Limits

The kit suits servers and workstations that require registered ECC DDR3 at 1.50V with CL11 timing. Systems that accept only unbuffered non-ECC DDR3, or platforms limited to lower densities per slot, cannot use these modules.

Deciding Specification

The registered ECC design combined with DDR3 1600 speed and CL11 latency is the single specification that determines compatibility; the memory controller and motherboard must explicitly support registered ECC DDR3 at this data rate.

Questions about this item

Will the registered ECC DDR3 modules require any firmware updates or component replacements during their service life?

The modules are 100% tested to JEDEC specifications and carry a lifetime warranty; no firmware updates or component replacements are expected for the DDR3 1600 registered ECC memory itself.

What is the first limit reached when the 16 GB kit runs at DDR3 1600 CL11 under sustained load?

The registered DDR3 1600 CL11 specification defines the maximum sustained data rate and latency; the memory controller will hit that bandwidth and timing ceiling before any other module limit appears.

How much heat and power do the four 4 GB sticks draw at 1.50 V during all-day operation?

Each module operates at the standard DDR3 1.50 V; total power draw and heat output scale with the four-stick 16 GB configuration running at the rated DDR3 1600 speed.
