8GB DDR5 4800 SODIMM for Lenovo ThinkCentre

This 8GB DDR5 4800 CL40 SODIMM upgrades Lenovo ThinkCentre M80q Gen 3, M90a Pro Gen 3 and M90q Gen 3 systems. It runs at 1.1V as a non-ECC unbuffered module with a single 1Rx16 rank. The 262-pin form factor fits the supported platforms directly.

Sustained JEDEC operation at CL40

The module follows JEDEC PC5-38400 timing without overclock headroom, so latency and bandwidth stay consistent under continuous workloads. ROHS-compliant construction and 100% factory testing keep error rates low during extended sessions. No heat spreader is fitted, relying on chassis airflow for thermal management.

Check slot count and maximum capacity first

Verify how many SODIMM slots your ThinkCentre model provides and the total memory ceiling before ordering. This single 8GB stick adds capacity but cannot enable dual-channel alone if only one slot is populated. Systems needing ECC or registered memory are not compatible with this unbuffered non-ECC design.

Questions about this item

How much power does this 1.1 V DDR5 module draw when the ThinkCentre runs continuously?

The module operates at the standard DDR5 voltage of 1.1 V, which keeps power draw low during all-day use in the supported ThinkCentre systems.

Which slot type must my Lenovo ThinkCentre have for this 262-pin SODIMM to fit?

Your ThinkCentre M80q Gen 3, M90a Pro Gen 3 or M90q Gen 3 must provide a standard DDR5 262-pin SODIMM slot.

Can I add this CL40 4800 MHz stick alongside the original memory that came in my M90q Gen 3?

Yes, the module meets JEDEC DDR5-4800 CL40 specs, so it will run at the same speed and timings as the factory-installed memory in those ThinkCentre models.
