SAMSUNG M378B5173CB0-CK0 8GB 2 x 4GB DDR3 1600MHz desktop RAM

SKU CH-HKCB-2HJYA

A dual-channel kit of two 4 GB DDR3 modules running at 1600 MHz with CL11 latency and 1.5 V operation

  • 8GB dual-channel kit expands multitasking headroom with two matched 4GB modules
  • 1600MHz DDR3 speed keeps data flowing for everyday workloads
  • CL11 latency delivers responsive timing for standard desktop tasks
  • 5V operation runs cool on typical motherboard memory slots
  • 240-pin DDR3 form factor fits a wide range of desktop boards

Samsung DDR3 Kit for Desktop Builds

This Samsung kit provides 8 GB of DDR3 memory in a matched pair of 4 GB modules. It is designed for desktop systems that use 240-pin DIMM slots and supports a data rate of 1600 MHz. The non-ECC unbuffered design suits standard consumer motherboards. Buyers who need ECC error correction or higher-capacity single modules should look elsewhere.

Thermals Power and Noise

DDR3 modules operate at a standard 1.5 V with no active cooling required. Passive heat spreaders on each stick keep temperatures within normal limits during typical workloads. Power draw remains low and the components produce no audible noise. Builders seeking lower-voltage 1.35 V operation or RGB lighting will not find those features here.

CL11 Latency at 1600 MHz

The modules run at CAS latency 11 (CL11) under the PC3-12800U specification. This timing determines how quickly the memory responds to read commands at the rated 1600 MHz speed. Systems that require tighter latencies or higher frequencies will need different modules.

Questions about this item

How do I install the 240-pin DDR3 modules and which orientation mistake is common?

Align the notch on each 240-pin module with the motherboard slot key, press straight down until both retention clips click, and avoid forcing the module in backwards — the notch is off-centre so it only fits one way.

What maintenance or replacement will the non-ECC DDR3 kit need over time?

Non-ECC DDR3 requires no scheduled maintenance; replacement is only needed if a module fails or if the system later requires ECC or higher-capacity memory.

At what CAS latency does the CL11 1600MHz kit hit its timing limit during sustained workloads?

The modules are rated at CL11 1600MHz; under sustained load the CAS 11 timing is the first fixed limit, as tighter latencies are not supported at this speed.
