16 GB DDR4 2666 SODIMM for HP Pavilion Gaming

This 16 GB DDR4 2666 CL19 module is built for HP Pavilion Gaming Notebook 15-dk0011TX, 15-dk0040nl and 15-dk0145tx. It installs in a 260-pin SO-DIMM slot and runs at 1.2 V without ECC or buffering. The single-stick kit suits owners who want a direct compatibility guarantee from Computer Memory Solutions.

260-pin DDR4 2666 interface decides fit

The stick uses the 260-pin DDR4 SO-DIMM form factor at 2666 MHz (PC4 21300) with CL19 19-19-19 timing. Systems that require ECC or registered memory will not accept this unbuffered non-ECC design. Buyers whose notebooks need ECC UDIMM or a different pin count cannot use this module.

Runs at 1.2 V under continuous load

The module operates at the standard 1.2 V DDR4 voltage during sustained workloads. All installed memory will run at the speed of the slowest module or the processor’s memory controller limit. A 64-bit operating system is required to address the full 16 GB capacity.

Questions about this item

What does the 2666 MHz rating mean once the module is installed in my Pavilion Gaming notebook?

The module will run at up to 2666 MHz, but the actual speed is limited by the processor and chipset in the notebook; if the CPU or existing memory runs slower, this stick will downclock to match.

How does the DDR4 2666 (PC4 21300) interface limit performance in practice?

The DDR4 2666 interface caps the theoretical bandwidth at 21300 MB/s; real-world throughput will be lower and cannot exceed what the notebook's memory controller supports.

Will this 260-pin SODIMM physically fit the memory slot in an HP Pavilion Gaming 15-dk0011TX?

Yes, the 260-pin DDR4 SO-DIMM form factor matches the slot used in the listed Pavilion Gaming models, and the module is unbuffered with no heat spreader to interfere with the laptop's cover.
