4GB DDR4 SODIMM for ThinkCentre S500z

This OWC module adds 4GB of DDR4 memory to a Lenovo ThinkCentre S500z. It is built for owners of that specific all-in-one who want a straightforward capacity increase. The stick is new and tested to meet the original manufacturer specifications.

260-pin DDR4 2133 CL15 1.2V specification

The single deciding spec is the 260-pin DDR4 2133MHz CL15 1.2V Non-ECC SODIMM form factor. Your ThinkCentre S500z must accept this exact speed, voltage, pin count and latency for the upgrade to work. Any mismatch in those values means the module will not be compatible.

Suits ThinkCentre S500z owners needing a single

This suits anyone upgrading a ThinkCentre S500z with one compatible slot. It does not suit buyers who want more storage, builders who need a second card, or systems that require ECC, registered, higher-speed or different-pin memory.

Highlights

  • Boosts system responsiveness with a 4GB DDR4 2133MHz module

  • CL15 latency supports snappy multitasking
  • 260-pin SODIMM fits the ThinkCentre S500z exactly

Questions about this item

Will the 2133 MHz speed run at that rate inside my ThinkCentre S500z?

The module is rated for DDR4 2133 (PC4-17000) and will operate at that speed provided the platform supports it; the S500z memory controller determines the final frequency.

Is the PC4-17000 label just marketing or does it limit bandwidth?

PC4-17000 denotes the JEDEC standard peak transfer rate of 17 GB/s for DDR4 2133; actual throughput depends on the system's memory controller and channel configuration.

Does the 260-pin SODIMM fit the ThinkCentre S500z slot without an adapter?

Yes, the 260-pin DDR4 SODIMM form factor matches the S500z memory slot exactly; no adapter or bracket is required.
