Targeted laptop upgrade

This 16 GB DDR4 SODIMM module is built for the Acer Predator Triton 500 PT515-51 series. It delivers 2666 MHz speed with CL19 latency and runs at 1.2 V without ECC or buffering.

Single-slot installation

The 260-pin stick fits one available SO-DIMM slot and uses major-brand chips in a 2Rx8 layout. No heat spreader is included, keeping the profile low for tight chassis clearance.

Capacity step from 8 GB

The platform supports up to 32 GB total, so adding this module doubles a typical 8 GB configuration. Buyers already at the 32 GB limit or needing ECC registered memory should look elsewhere.

Questions about this item

What CAS latency does the CM2048642666SO module run at when installed in a Predator Triton 500?

The module operates at CL19 with 19-19-19 timings at 2666 MHz.

How much heat does the stick generate during continuous operation without a spreader?

Running at 1.2 V unbuffered, it produces minimal heat; the laptop's existing cooling handles sustained loads.

Which slot configuration must the Triton 500 already have free for this 16 GB kit to work?

One vacant 260-pin SODIMM slot — the system maxes at 32 GB, so a single empty slot accepts the 16 GB module.
