RAM upgrades on refurb ThinkPads
Most P-series and T-series refurb units ship under-RAMmed — SO-DIMM upgrade is the highest-value fix.
Before buying: confirm DDR4 vs DDR5 generation matches your exact model year. Check Lenovo PSREF or HMM for max GB and slot count.
Refurb tip: 16 GB refurb + 32 GB kit often beats buying 32 GB new if chassis is same generation.
- 32 GB SO-DIMM kit — Match DDR generation
- 64 GB kit — If HMM supports 2×32 GB
