Total Micro Technologies 862974B21TM 8GB DDR4 desktop RAM

SKU CH-JWSF-SW7EJ MPN 862974B21TM

ECC DDR4 DIMM module rated at 2400 MHz with CL17 latency and 1.20 V operation

  • Capacity8GB
  • SpeedDDR4 2400 (PC4 19200)
  • CAS LatencyCL17
  • Voltage1.20V
  • ECCECC
  • BIOS/Performance ProfileIntel XMP 2.0
  • 8GB DDR4 capacity expands system memory for demanding workloads
  • 2400 MHz speed delivers responsive data throughput
  • ECC error checking protects data integrity in critical tasks
  • CL17 CAS latency provides efficient memory access timing
  • 20V operation reduces power draw during sustained use

8GB DDR4 ECC Module for Server Builds

This 8GB DDR4-2400 module adds ECC-protected memory to compatible HPE ProLiant Gen9 Entry servers. The unbuffered DIMM runs at 1.20V with CL17 latency and includes an Intel XMP 2.0 profile for straightforward configuration. It suits administrators who need single-module capacity expansion without registered buffering.

288-Pin DIMM Fits Standard DDR4 Slots

The stick uses the industry-standard 288-pin DDR4 form factor and measures 7.8 inches long by 3.5 inches wide with a 750 mil thickness. It requires a motherboard that accepts unbuffered ECC DDR4 memory and an available DIMM slot. The single-rank design leaves additional slots free for future upgrades.

Low-Voltage Operation Limits Heat and Power Draw

At 1.20V the module draws minimal power during typical server workloads, keeping thermal output low inside dense chassis. Unbuffered signal processing reduces electrical load on the memory controller. The green PCB and standard-height heat spreader allow unrestricted airflow from existing system fans.

Questions about this item

What is the CAS latency figure that determines the first timing limit under sustained use?

The module runs at CL17, so each access cycle waits 17 clock ticks before data is returned.

How much heat and power does the 1.20 V DDR4 DIMM produce when running all day?

At 1.20 V the stick draws minimal power and stays cool enough for passive airflow in a server chassis.

Which 288-pin unbuffered ECC DIMM slot must the motherboard already provide for this module to work?

A standard DDR4 288-pin DIMM slot with unbuffered ECC support is required.
