DDR4 2400 SO-DIMM kit for Lenovo ThinkPad

This 16GB kit contains two 8GB DDR4 2400 SO-DIMM modules built for Lenovo ThinkPad P51s, P52s, T470 and T470p laptops. It uses 260-pin unbuffered non-ECC memory running at 1.2V with CL17 timing. The kit suits owners of those specific models who need to reach the platform's 32GB maximum across two slots.

Thermals noise and power in daily use

Standard DDR4 SO-DIMM modules without heat spreaders operate within the laptop's existing thermal design at 1.2V. Power draw follows the DDR4 2400 specification under normal workloads. Acoustic output is unchanged because the memory adds no moving parts and relies on the system's own cooling.

CL17 timing decides fit

The modules run at 17-17-17 CAS latency at DDR4 2400. Buyers whose firmware or workload requires a different latency value should verify compatibility before ordering. This kit will not suit systems limited to single-rank modules or those requiring ECC or registered memory.

Questions about this item

How do I install the CM1024642400SO modules in my ThinkPad?

Power off the laptop, remove the base cover, align each 260‑pin SO‑DIMM with the slot key, press in evenly until the side clips lock, then refit the cover.

What maintenance will this DDR4 kit need later?

No scheduled maintenance is required; if a module fails it is covered by a limited lifetime exchange from Computer Memory Solutions.

What limit appears first under sustained load?

The system caps at 32 GB across its two sockets, so this 16 GB kit leaves no room for further expansion.
