System-Specific Upgrade

This 8GB DDR4 SO-DIMM module is built for Lenovo ThinkPad L470, L480, L570 and L580 notebooks. It targets owners of those models who need a straightforward capacity increase without guessing at compatibility. The 260-pin form factor fits the factory memory slots in each listed system.

Single-Slot Installation

The stick occupies one SO-DIMM socket and runs at 1.2V with unbuffered, non-ECC operation. CL17 timing at 2400MHz matches the platform's native memory controller settings. Because the laptops support two slots and up to 32GB total, this single 8GB rank leaves the second socket free for a matching module later.

Sustained Workload Stability

Major-brand DRAM chips and the manufacturer's validation process keep error rates low during long compile, rendering or virtualisation sessions. The 2Rx8 organisation spreads the load across two ranks, helping the memory controller maintain throughput when the CPU stays at high utilisation for extended periods.

Questions about this item

How does the CL17 latency affect performance during sustained workloads?

CL17 timing means each memory request waits seventeen cycles before data transfer begins; under sustained use this latency becomes the first bottleneck before bandwidth limits appear.

Will the module run hot or draw extra power during all-day operation?

The stick operates at 1.2 V with no heat spreader, so power draw stays low and temperatures remain within standard SO-DIMM limits for continuous use.

Which ThinkPad models must I already own for this upgrade to work?

This 8 GB DDR4 2400 SODIMM is validated for Lenovo ThinkPad L470, L480, L570 and L580 systems with 260-pin slots.
