SAMSUNG

SAMSUNG M378A1K43DB2-CTD 8GB DDR4 2666MHz CL19 288-pin UDIMM 1.2V desktop RAM

SKU CH-PBGX-F43QY

8 GB DDR4 desktop module running at 2666 MHz with CL19 timing and 1.2 V operation

  • 8GB DDR4 capacity handles everyday multitasking smoothly
  • 2666MHz DDR4 speed moves data quickly through the system
  • CL19 latency keeps response times low for routine workloads
  • 2V operation reduces power draw and heat output
  • 288-pin UDIMM form factor fits standard desktop motherboard slots

Samsung 8 GB DDR4 2666 MHz UDIMM

This Samsung module provides 8 GB of DDR4 memory at 2666 MHz for desktop computers. It uses a 288-pin UDIMM form factor and operates at 1.2 V with a CAS latency of 19. The part number M378A1K43DB2-CTD identifies this specific unbuffered DIMM.

Suits standard desktop upgrades.

This memory suits users upgrading a standard desktop PC that accepts unbuffered DDR4 UDIMMs. It is not for systems requiring registered or load-reduced modules, nor for boards limited to lower speeds or different pin counts. Buyers needing ECC or higher capacities should look elsewhere.

CL19 latency at 2666 MHz

The key specification is the CL19 timing at the rated 2666 MHz speed. This latency value determines how quickly the module responds to read commands within each cycle. Verify that your motherboard supports this timing at the desired frequency before purchase.

Questions about this item

Does this 288-pin DDR4 UDIMM need a motherboard slot that also supports 1.2 V operation?

Yes, the module runs at 1.2 V, so the board must accept standard DDR4 voltage.

Can I add this CL19 stick to an existing 2666 MHz kit without changing BIOS timings?

The board will down-clock all modules to the slowest CAS latency, so the new stick will run at CL19 alongside the old kit.

How can I confirm the module is recognised at 2666 MHz after installation?

Open Task Manager or CPU-Z and verify the speed reads 2666 MHz with CL19 timings.
