8GB DDR4 module for Lenovo ThinkCentre workstations

This 8GB DDR4 2666MHz UDIMM is built for Lenovo ThinkCentre M920s, M920t, P330 and P330 G2 systems. It suits office users and IT teams who need a straightforward capacity increase without configuration changes. The module follows JEDEC specifications and is tested for warranty-safe upgrades in those models.

Standard 1.2V operation with no heat spreader

Running at 1.2V and CL19 latency, the unbuffered non-ECC stick draws minimal power and produces no audible noise. Its low-profile design fits the compact chassis of the supported ThinkCentre units. Backward compatibility with 2133MHz and 2400MHz buses allows it to slot into mixed-speed configurations without manual tuning.

Replaces slower or smaller DDR4 sticks in the same

Swapping a 4GB 2133MHz module for this 8GB 2666MHz part doubles capacity and raises bandwidth in a single step. The upgrade is worthwhile when multitasking stalls or larger datasets exceed the original memory ceiling. Buyers needing ECC, registered DIMMs or capacities beyond 8GB per slot should look elsewhere.

Perguntas sobre este artigo

How do I install this 288-pin UDIMM in a ThinkCentre M920s, and what step do people often miss?

Power off, unplug, open the case, align the notch on the module with the slot key, press firmly until both clips click, then power on and verify 2666 MHz in BIOS; the missed step is forgetting to seat both retention clips fully.

What maintenance or replacement will this 8GB DDR4 module need over its lifetime?

No scheduled maintenance is required; keep dust out of the DIMM slots and ensure the 1.2 V supply remains stable, and the module is covered by OWC's limited lifetime warranty if a fault ever appears.

What limit appears first when this CL19 memory runs sustained workloads on a P330 G2?

The CL19 latency at 2666 MHz sets the throughput ceiling before thermal throttling becomes a factor, since the unbuffered UDIMM has no heat spreader and operates at standard 1.2 V.
