Targeted DDR4 SODIMM upgrade
This 8 GB DDR4 2400 MHz module is built for Lenovo ThinkPad P51s, P52s, T470 and T470p laptops. It arrives as a single 260-pin SO-DIMM using non-ECC, unbuffered chips at 1.2 V. Buyers with other DDR generations or desktop platforms cannot use this stick.
DDR4 2400 SO-DIMM limits
The memory runs at PC4 19200 with CL17 timing and a 2Rx8 rank structure. Maximum system capacity is 32 GB across two sockets, so a single module leaves one slot free. Systems requiring ECC or registered memory will not accept this kit.
Pre-install checklist
Verify your exact model number matches the listed 20HB, 20JY, 20LB, 20HD, 20HE, 20JM, 20JN, 20J6 or 20J7 series. Confirm the laptop has an empty 260-pin DDR4 SO-DIMM slot and that BIOS is current. Machines needing more than 32 GB total or registered DIMMs are not compatible.

Questions about this item
Should I pick the 8 GB stick or add a second one to reach 32 GB?
Each slot takes one 260-pin DDR4 SODIMM; the platform supports two slots for a maximum of 32 GB, so a single 8 GB module leaves room for another identical stick later.
What does the 2400 MHz rating actually deliver in a ThinkPad P51s or T470?
The module runs at DDR4 2400 (PC4 19200) with CL17 timing at 1.2 V, giving the rated bandwidth when the laptop's memory controller is set to that speed.
Is the 260-pin SO-DIMM interface the limiting factor for speed on these models?
The 260-pin DDR4 SO-DIMM form factor carries the 2400 MHz signal; the platform's memory controller caps the operating frequency, not the connector itself.
