System-specific DDR5 SODIMM for Lenovo Legion Slim

This 8 GB module is built to the exact electrical and physical profile required by the Lenovo Legion Slim 5 16IRH8. It uses 262-pin DDR5 technology and runs at the JEDEC-standard 5200 MT/s with CL42 latency. The single-rank 1Rx8 layout and 1.1 V operation match the notebook's memory controller without any configuration changes.

Fits a single SO-DIMM slot in the Legion Slim 5

Installation uses the existing SO-DIMM socket and needs no extra cooling because the module has no heat spreader. The unbuffered, non-ECC design keeps the memory controller load low and leaves any second slot free for a matching stick if the chassis provides one. JEDEC compliance means the BIOS will train the module at its rated speed automatically.

Suits owners of the Legion Slim 5 16IRH8 who need

Buyers with a different laptop model or a desktop board should not use this module because the pin-out and SPD profile are tuned for one specific system. Anyone who wants ECC error correction, registered buffering or a higher voltage will need a different memory type altogether.

Questions about this item

Will the 5200 MHz DDR5 module throttle under sustained heavy workloads?

The module runs at standard JEDEC 5200 MHz CL42 without a heat spreader, so sustained heavy loads may push it to thermal limits before the CPU does.

How much heat and power does this 1.1 V SODIMM add during all-day use?

At 1.1 V the 8 GB stick draws minimal power and produces little extra heat, keeping laptop thermals and fan noise close to stock levels.

Does my Legion Slim 5 16IRH8 need a free 262-pin DDR5 slot to install this?

Yes, the upgrade requires an open 262-pin DDR5 SO-DIMM slot; the laptop must support DDR5 5200 non-ECC unbuffered memory.
