A-Tech 48GB (6x8GB) DDR3 1600 ECC RDIMM 2Rx4 1.5V memory upgrade

SKU CH-4KA1-CZDFW

A 48GB kit of six 8GB DDR3 1600MHz ECC registered DIMMs for Dell PowerEdge 12th Gen rack servers

  • Capacity48GB (6 x 8GB)
  • Type240-Pin DDR3 SDRAM
  • SpeedDDR3 1600 (PC3 12800)
  • CAS LatencyCL11
  • Voltage1.50V
  • ECCYes

Capacity 48GB (6 x 8GB)

  • 48 GB capacity across six modules expands server memory headroom
  • DDR3 1600 MHz PC3-12800 speed supports demanding 12th Gen workloads
  • ECC Registered 2Rx4 design protects data integrity in multi-socket systems
  • 5 V operation matches Dell PowerEdge R320 through R920 specifications
  • Tested compatibility with Xeon E5-1400, E5-2400, E5-2600, E5-4600 and E7 series CPUs

Purpose-Built Server Memory

This 48GB kit contains six 8GB DDR3 registered DIMMs validated for Dell PowerEdge 12th generation rack servers including the R320, R420, R420xr, R520, R620, R720, R720xd, R820 and R920. It targets administrators who need ECC error correction and registered buffering for stable operation under sustained workloads. The modules are not compatible with desktop or laptop platforms that require unbuffered non-ECC memory.

Registered DIMM Construction

Each module uses a 240-pin DDR3 form factor with a 2Rx4 dual-rank organisation and major-brand chipsets. Registered buffering reduces electrical load on the server memory controller, allowing the full six-module population supported by these platforms. The absence of heat spreaders keeps the profile low for dense rack chassis while the 1.5V operating voltage matches the original server specification.

Thermals and Power in Operation

Running at DDR3 1600 (PC3-12800) with CL11 latency, the kit draws 1.5V per module under normal server loads. Registered DIMMs typically operate within standard server airflow designs without additional cooling. ECC functionality detects and corrects single-bit errors, helping maintain data integrity during continuous operation in the listed PowerEdge systems.

Questions sur cet article

What DDR3 speed and PC3 rating does this ECC RDIMM kit run at?

The kit operates at DDR3 1600 MHz with a PC3-12800 rating, delivering 12800 MB/s peak bandwidth per module.

Which Dell PowerEdge 12th Gen rack servers accept these 240-pin registered DIMMs?

Compatible models include the R320, R420, R420xr, R520, R620, R720, R720xd, R820 and R920.

How should the six 2Rx4 modules be seated across the memory channels?

Follow the server manual for channel population order; a common mistake is filling slots sequentially instead of balancing ranks across channels.
