SAMSUNG M393B1K70CHD-YH9 8GB DDR3-1333 ECC 1.35V desktop RAM

SKU CH-JDSK-XKPB1

8GB DDR3-1333 ECC desktop memory running at 1.35V for data integrity and lower power draw

  • ECC protection prevents data corruption for critical workloads
  • Low 1.35V operation cuts power draw and heat
  • DDR3-1333 speed delivers 10600 MT/s bandwidth
  • 2RX4 organisation boosts signal integrity at load
  • Single 8GB module simplifies capacity upgrades

8 GB DDR3-1333 ECC module

This Samsung M393B1K70CHD-YH9 module adds 8 GB of DDR3 memory running at 1333 MT/s. It is built for desktop systems that require Error-Correcting Code protection for data integrity. The 1.35 V operating voltage lowers power draw compared to standard DDR3. It suits workstations and servers where stability matters more than raw speed.

Fits DDR3 ECC slots with 2RX4 organisation

The stick uses a 2RX4 configuration and plugs into standard DDR3 DIMM slots that support ECC. Because it runs at 1.35 V, the motherboard must accept low-voltage DDR3 modules. ECC functionality only works when the platform chipset and BIOS enable it. No extra cooling or power connectors are required beyond the slot itself.

Replaces non-ECC or higher-voltage DDR3

Upgrading from standard 1.5 V DDR3 without ECC gives error detection and reduced heat output. The jump is worth it when the system handles long compute jobs, file-server duties or virtualisation workloads. If the board does not support ECC, the module will still run but without correction benefits.

Questions about this item

How does the 1.35V operating voltage affect heat and power draw under sustained load?

The low 1.35V operation reduces power consumption and minimises heat generation compared to standard 1.5V DDR3 modules, helping keep the system cooler during all-day use.

Does the ECC function require a specific motherboard chipset to work?

Yes, ECC error correction only functions when the motherboard and CPU support ECC memory; standard consumer desktop platforms typically disable this feature.
