Lenovo ThinkPad T14 Gen 4 (Intel) upgrades
LPDDR5x models (16GB or 32GB) have all memory soldered and no RAM slot, so check the SKU's memory type before buying. DDR4 and DDR5 models have soldered memory plus one SO-DIMM slot.
- SO-DIMM (DDR4 models): DDR4 SO-DIMM · 8 GB soldered · up to 40 GB total · 3200 MT/s
- SO-DIMM (DDR5 models): DDR5 SO-DIMM · 16 GB soldered · up to 32 GB total · 5200 MT/s
- M.2 2280 PCIe 4.0 x4 NVMe slot: SSD M.2 2280 (NVMe) · up to 2 TB
SO-DIMM (DDR4 models) DDR4 SO-DIMM · 8 GB soldered · up to 40 GB total · 3200 MT/s
DDR4 models only: 8GB soldered plus one SO-DIMM slot. Populate the slot for dual-channel. The 32GB limit is Lenovo's tested figure, so a larger module is unverified. Non-ECC unbuffered is inferred, not stated by Lenovo.

SO-DIMM (DDR5 models) DDR5 SO-DIMM · 16 GB soldered · up to 32 GB total · 5200 MT/s
DDR5 models only: 16GB soldered plus one SO-DIMM slot. Some SKUs ship with the slot empty and may run single-channel. Faster DDR5-5600 modules run at 5200 at most. The 16GB limit is Lenovo's tested figure. Non-ECC is inferred.
M.2 2280 PCIe 4.0 x4 NVMe slot SSD M.2 2280 (NVMe) · up to 2 TB
Only one internal drive is supported and there is no 2.5" bay. The 2TB maximum is Lenovo's tested figure, so a larger drive may work but is unsupported. SD reader and WWAN slot were not verified.
