Purpose-built upgrade

This 32 GB kit contains two 16 GB DDR4 SO-DIMM modules designed for Lenovo ThinkPad T460p, T480, T570 and T580 laptops. It targets owners of those models who need the maximum 32 GB capacity supported by the two available sockets. The modules are non-ECC, unbuffered and carry a CL17 latency rating. Buyers whose systems require ECC or registered memory cannot use this kit.

Thermals and power

Each module operates at the standard DDR4 voltage of 1.2 V and has no heat spreader, relying on the laptop's internal airflow for cooling. In typical office workloads the sticks run cool and silent because there are no moving parts on the memory itself. Power draw remains low and consistent with the platform's original memory specification. The low-profile design fits the tight clearance inside the listed ThinkPad chassis.

Sustained load behaviour

Under continuous heavy use such as large dataset processing or virtualisation the memory maintains its rated 2400 MHz speed and 17-17-17 timings without throttling. The dual-rank 2Rx8 organisation helps sustain bandwidth across both channels when both slots are populated. Stability is backed by the manufacturer's lifetime exchange or repair warranty against manufacturing defects. Systems limited to lower speeds will automatically downclock the modules.

Questions about this item

How do I install the 260-pin DDR4 SO-DIMM modules into my ThinkPad T480 and what step is often missed?

Power off, unplug, remove the battery, open the memory door, insert both 16 GB sticks at an angle until the clips click, then reassemble; the step people skip is reseating the battery before booting.

What maintenance or replacement will the 32 GB kit need over its lifetime?

No scheduled maintenance is required; if a module fails it is covered by the manufacturer's limited lifetime warranty, so you would simply request a replacement stick.

What limit appears first when the CL17 2400 MHz memory runs under sustained heavy load?

The CAS latency of 17 cycles at 1.2 V sets the timing floor; thermal throttling is unlikely without a heat spreader, so latency remains the first bottleneck.
