HP Samsung 8GB DDR4-2666 CL19 260-pin SODIMM M471A1K43CB1-CTD L04439-501

SKU CH-RZW4-BMKZF

An 8 GB DDR4-2666 SODIMM with CL19 timing and 1.2 V operation for laptop upgrades

  • Type260-Pin DDR4 SO-DIMM
  • 8 GB capacity expands laptop multitasking headroom
  • DDR4-2666 speed delivers responsive data throughput
  • CL19 latency keeps timing tight
  • 2 V operation reduces power draw
  • 260-pin SO-DIMM fits standard laptop slots

8 GB DDR4-2666 laptop module

This 8 GB DDR4-2666 SODIMM upgrades notebooks that accept 260-pin unbuffered memory. It suits owners who need extra capacity for everyday multitasking or a direct replacement for a failed stick.

CL19 timing at 1.2 V

The module runs at CL19 latency with a standard 1.2 V supply. Its 260-pin SO-DIMM edge connector fits the DDR4 slots found in compatible laptops, so installation is a simple push-in action.

DDR4-2666 bandwidth ceiling

The PC4-21300 interface caps throughput at the DDR4-2666 data rate. Systems limited to lower memory speeds will down-clock the module, while workloads needing higher bandwidth or ECC protection must look elsewhere.

Highlights

  • 8 GB capacity expands laptop multitasking headroom
  • DDR4-2666 speed delivers responsive data throughput
  • CL19 latency keeps timing tight
  • 2 V operation reduces power draw
  • 260-pin SO-DIMM fits standard laptop slots

Questions about this item

What speed does the DDR4-2666 interface actually run at in a laptop?

The module is rated for 2666 MT/s (PC4-21300) and will operate at that speed if the platform supports it; otherwise it down-clocks to the highest speed the memory controller allows.

What physical slot does the 260-pin SO-DIMM require?

It fits a standard 260-pin DDR4 SO-DIMM socket, which is keyed differently from older 204-pin sockets to prevent incorrect insertion.

Which orientation step do people often miss when seating the stick?

Align the notch on the module edge with the key in the slot, insert at roughly 30 degrees, then press down firmly until both side clips click into the notches on the PCB.
