Four green DDR4 memory modules with gold contacts, no heat spreaders

Kingston Technology Corp.

Kingston Technology Corp. KVR21R15D4K4/64I 64GB (4 x 16GB) DDR4 2133 ECC Registered server RAM

SKU CH-ZXJV-VAGVE MPN KVR21R15D4K4/64I

64GB kit of four 16GB DDR4 2133 ECC registered modules at 1.20V with CL15 timing

  • Capacity64GB (4 x 16GB)
  • Type288-Pin DDR4 SDRAM
  • SpeedDDR4 2133 (PC4 17000)
  • CAS LatencyCL15
  • Timing15-15-15
  • Voltage1.20V
  • ECC protection maintains data integrity with registered DDR4 design
  • 64 GB total capacity across four 16 GB modules
  • DDR4 2133 speed rated at PC4 17000 bandwidth
  • CL15 latency with 15-15-15 timing for responsive operation
  • Low 1.20 V voltage reduces server power draw

Server Memory Kit

This Kingston ValueRAM kit provides 64GB of DDR4 capacity across four 16GB registered DIMMs. It is built for servers and workstations that require error-correcting memory for data integrity.

Registered ECC Requirement

The modules use registered ECC DDR4 at 2133 MT/s with CL15 timing and 1.20V operation. Systems without registered ECC support or those needing unbuffered memory cannot use this kit.

Sustained Operation

Registered buffering reduces electrical load on the memory controller during continuous workloads. ECC correction maintains data accuracy over long periods without a heat spreader.

Perguntas sobre este artigo

Does my motherboard need 288-pin DDR4 slots to use this 64GB kit?

Yes, the kit uses 288-pin DDR4 SDRAM modules; your server board must provide DDR4 DIMM slots that accept registered ECC memory.

Can I add these CL15 registered modules to a system that already runs CL17 unbuffered DDR4 2133?

Registered and unbuffered DIMMs cannot be mixed; the memory controller will not initialise both types together.

How do I confirm the kit runs at DDR4 2133 with 15-15-15 timings after installation?

Enter the BIOS or use a tool like CPU-Z; the SPD should show 2133 MT/s, CL15-15-15 at 1.20 V.
