OWC 8GB DDR5 4800 UDIMM upgrade

This OWC module adds 8GB of DDR5 4800 memory to compatible Lenovo ThinkCentre desktops. It operates at 1.1V with CL40 latency and uses a single-rank 1Rx16 layout. The 288-pin unbuffered non-ECC design follows JEDEC standards for a warranty-safe installation.

Ideal for ThinkCentre M80s, M80t, M90s.

Builders needing ECC error correction, registered DIMMs, higher capacities per module or speeds above 4800 MT/s should look elsewhere. Systems outside the listed Lenovo models may not recognise the module or could require different specifications.

Confirm your ThinkCentre model

Verify the motherboard has a free 288-pin DDR5 slot and supports 1.1V non-ECC unbuffered memory. Check the current memory population to ensure the single-rank 1Rx16 module matches the platform requirements.

Perguntas sobre este artigo

Does my Lenovo ThinkCentre M80s Gen 3 need a free 288-pin UDIMM slot to accept this 8GB DDR5 4800 module?

Yes, the module uses a standard 288-pin UDIMM form factor, so an empty DDR5 DIMM slot on the motherboard is required for installation.

Can I keep my existing DDR5 4800 CL40 memory and add this 1Rx16 8GB stick without changing BIOS settings?

The module follows JEDEC DDR5 4800 CL40 1.1V specs, so it will run at the same speed and timings as matching factory memory without manual configuration.

How do I confirm the new 8GB module is recognised at 4800 MT/s after I install it?

Check the memory speed in Task Manager’s Performance tab or run CPU-Z; both will show the module operating at 4800 MT/s with CL40 latency when seated correctly.
