Two black 288-pin DIMM modules on green PCB

SAMSUNG

SAMSUNG M378A2K43CB1-CTD 16 GB DDR4 2666 MHz 2 x 8 GB desktop RAM

SKU CH-HK1C-3RFH7

A 16 GB DDR4 dual-channel kit running at 2666 MHz with CL19 timing for desktop upgrades

  • 16 GB dual-channel kit lifts multitasking headroom
  • 2666 MHz DDR4 speed keeps data flowing smoothly
  • CL19 latency reduces access delays for responsive feel
  • 2 V operation cuts power draw and heat output
  • 288-pin DIMM layout fits standard desktop motherboards

16 GB DDR4 2666 MHz dual-channel kit

This 16 GB kit uses two 8 GB DDR4 modules rated at 2666 MHz with CAS latency 19. It is built for desktop PCs and servers that accept standard 288-pin DIMMs and run at 1.2 V. The black modules suit general office workloads, light content creation and everyday multitasking.

Simple 288-pin DIMM installation

Align the notch on each module with the slot key, press down firmly until the retention clips click, then power on. The kit runs at the JEDEC-standard 1.2 V so no manual voltage adjustment is required. If the system does not post, reseat both sticks and test them one at a time to isolate a faulty module or a bad slot.

Check motherboard DDR4 support and slot count

Verify that your board accepts DDR4 memory in 288-pin DIMM form and has at least two free slots for dual-channel operation. Confirm the maximum supported speed and total capacity in the motherboard manual, because exceeding those limits can prevent boot or force a lower speed. Systems that require ECC or registered memory will not work with this non-ECC unbuffered kit.

Questions about this item

How can I confirm the kit is running at 2666 MHz after installation?

Open Task Manager or BIOS and verify the memory speed shows 2666 MHz; the modules are rated for that clock speed out of the box.

What comes in the package and do I need any extra parts?

The box contains two 8 GB DDR4 288-pin DIMMs in black; no additional cables, brackets or coolers are required for standard desktop installation.

Should I choose the 2 x 8 GB kit or a single 16 GB module?

The 2 x 8 GB kit enables dual-channel operation on most desktop boards, giving higher bandwidth than a single 16 GB stick at the same 2666 MHz rating.
