Lenovo ThinkPad P1 Gen 5 compatible SODIMM kit

This 32 GB kit contains two 16 GB DDR5 SODIMM modules built for the Lenovo ThinkPad P1 Gen 5 series. Each stick runs at 4800 MT/s with a CAS latency of CL40 and operates at 1.1 V. The unbuffered, non-ECC design matches the laptop's factory memory specification.

DDR5 SODIMM speed and voltage limits

DDR5 SODIMM slots in this platform accept modules up to 4800 MT/s at 1.1 V. Faster modules will downclock to this speed, while higher-voltage parts may not be supported by the system's memory controller. The 262-pin form factor is fixed, so desktop DIMMs cannot be used.

1Rx8 rank organisation for dual-channel operation

The kit uses a 1Rx8 configuration across both modules, enabling dual-channel bandwidth on the two-slot motherboard. Builders who need more than 32 GB total capacity cannot expand further because the laptop provides only two SODIMM sockets.

Questions about this item

Should I choose the 16 GB single module or the 32 GB kit of two 16 GB modules?

The 32 GB kit provides two matched 16 GB modules for dual-channel operation, while a single 16 GB module would run in single-channel mode and limit total capacity.

What does the DDR5 4800 CL40 rating mean for real-world performance in my ThinkPad P1 Gen 5?

The modules run at 4800 MT/s with a CAS latency of 40 cycles, delivering the standard JEDEC DDR5 base speed and latency for stable operation in the ThinkPad P1 Gen 5.

Does the 262-pin SODIMM interface limit bandwidth or compatibility compared to a desktop DIMM?

The 262-pin SODIMM form factor is the standard DDR5 laptop interface; it carries the full 4800 MT/s signal and fits only SODIMM slots, not desktop DIMM sockets.
