POSIFLEX XT-7515 SODIMM kit

This 16 GB kit contains two 8 GB DDR4 2666 SODIMM modules built for the POSIFLEX XT-7515 terminal. It targets system integrators and IT teams who need a validated memory upgrade for that specific point-of-sale platform.

DDR4 2666 CL19 limits

The modules run at 2666 MT/s with CL19 latency and 1.20 V, matching the PC4-21300 standard used by the terminal. Bandwidth and timing are fixed by the platform memory controller, so the kit cannot exceed the host's supported data rate or latency settings.

260-pin unbuffered build

Each stick uses a 2Rx8 260-pin layout without a heat spreader, keeping the profile low for the fanless chassis. Major-brand Samsung, Micron or Hynix ICs are used, and the unbuffered non-ECC design means the terminal's memory slots accept the kit directly with no extra configuration.

Questions about this item

Should I pick the 16 GB kit or a different capacity for my POSIFLEX XT-7515?

This kit provides 16 GB as two 8 GB modules, matching the dual-channel layout the XT-7515 expects for best throughput.

What does the 2666 MT/s rating actually deliver inside the terminal?

The memory runs at DDR4 2666 (PC4-21300) with CL19 timing, giving the bandwidth the POS system's chipset is designed to use.

Will the 260-pin SODIMM interface fit and what speed ceiling does it impose?

Yes — the 260-pin DDR4 SODIMM form factor is the exact slot type in the XT-7515, and the interface caps transfer rate at the module's rated 2666 MT/s.
