System-specific DDR5 upgrade for Lenovo

This OWC module delivers 16 GB of DDR5 4800 memory built to JEDEC standard. It targets owners of the listed Lenovo workstations who need a straightforward capacity increase without configuration changes.

Unbuffered 288-pin UDIMM with no heat spreader

The stick uses a standard 288-pin UDIMM form factor and runs at 1.1 V. Its low-profile design fits tight workstation slots, and the unbuffered layout means it drops into compatible DIMM sockets without extra registration steps.

Single 16 GB rank at CL40 latency

The 1Rx8 organisation provides one rank per module at CAS latency 40. Buyers who need ECC error correction or registered buffering for other platforms cannot use this part.

Questions about this item

What speed does the DDR5 4800 PC5-38400 CL40 specification actually run at in the ThinkStation P3 or P360 Tower?

The module is rated at 4800 MT/s (PC5-38400) with CL40 latency and will operate at that speed provided the platform firmware supports DDR5-4800.

Does the 288-pin unbuffered DIMM fit the standard UDIMM slots in the ThinkStation P3 Tower and P360 Tower without a heat spreader?

Yes, it is a standard 288-pin unbuffered DIMM without a heat spreader, designed for the UDIMM slots in both ThinkStation models.

What is the correct way to seat this single 16 GB 1Rx8 module, and what common step is missed during installation?

Align the notch with the slot key, press firmly until both retention clips click, and verify the module is fully seated; the step often missed is confirming both clips have locked.
