OWC 32GB DDR5 UDIMM for Lenovo ThinkCentre
This OWC module is a 32GB DDR5 4800 PC5-38400 CL40 2Rx8 288-pin 1.1V Non-ECC UDIMM built for specific Lenovo ThinkCentre desktops. It targets owners of the M80s Gen 3, M80t Gen 3, M90s Gen 3, M90t Gen 3 and neo 70t Gen 3 who need a single high-capacity stick. The part number 4U8D52R832GB replaces Lenovo 4X71K53892 and meets JEDEC and RoHS standards.
Suits ThinkCentre Gen 3 owners needing 32GB per slot
Buyers with the listed ThinkCentre models can install this unbuffered DIMM as a straightforward DIY upgrade. Systems that require registered or ECC memory cannot use this part. Workstations needing speeds above 4800MHz or lower CAS latency should look elsewhere. The module has no heat spreader, so cases with very restricted airflow around the memory slots may not be ideal.
32GB density in a single DDR5 UDIMM
The deciding specification is the 32GB capacity combined with the DDR5 4800 PC5-38400 CL40 2Rx8 1.1V unbuffered UDIMM form factor. If your ThinkCentre model and motherboard support this exact density, speed, voltage and rank configuration, the module will work. Verify your system documentation for maximum supported capacity per slot and total memory limit before purchasing.

Questions about this item
Should I pick the 32GB module or combine smaller kits for my ThinkCentre M90t Gen 3?
The single 32GB DIMM fills one slot and leaves room for a second identical module later, matching the 2Rx8 rank layout the platform expects.
What does the 4800 CL40 rating deliver in everyday workloads on a Lenovo neo 70t Gen 3?
At 4800 MT/s with CL40 timing the module runs at the standard JEDEC DDR5 speed, giving full bandwidth without manual tuning.
Does the 288-pin DDR5 interface limit the maximum transfer rate on these ThinkCentre desktops?
The 288-pin DDR5 UDIMM socket caps at the rated 4800 MT/s PC5-38400 data rate; higher speeds would need a different platform.
