Two green DDR5 SODIMM sticks, 32GB kit, no heat spreader

OWC

OWC 32GB (2x16GB) DDR5 5200 CL42 1Rx8 SODIMM Memory Upgrade

SKU CH-K4SC-RENMV

A 32 GB DDR5 SODIMM kit running at 5200 MT/s with CL42 latency for Lenovo Legion Pro 5 16ARX8 and Pro 7 16ARX8H laptops

Capacity 32GB (2 x 16GB)

  • 32GB total capacity for multitasking headroom with two 16GB modules
  • DDR5 5200 speed transfers data at PC5-41600 bandwidth
  • CL42 latency and 1.1V voltage meet JEDEC standard for stable operation
  • 262-pin SODIMM form factor fits Lenovo Legion Pro 5 16ARX8 and Pro 7 16ARX8H
  • 1Rx8 unbuffered non-ECC design installs without extra configuration

System-Specific DDR5 Upgrade Kit

This 32 GB kit contains two 16 GB DDR5 SODIMM modules built to JEDEC standards for 1.1 V operation. It targets owners of the Lenovo Legion Pro 5 16ARX8 and Legion Pro 7 16ARX8H who need more memory capacity for everyday workloads.

262-Pin SODIMM Form Factor

Each stick uses the 262-pin unbuffered non-ECC layout required by those laptops, so installation simply means opening the service panel and slotting the modules into the two available sockets. No heat spreader is fitted, keeping the profile low enough for the factory cooling design.

CL42 Latency at 5200 MT/s

The PC5-41600 rating delivers 5200 MT/s transfer rates with CL42 timing, giving ample bandwidth for multitasking, content creation and large data sets. Builders wanting ECC error correction, registered buffering or speeds above 5200 MT/s will need a different module class.

Questions about this item

Does the 1.1V DDR5 voltage reduce heat during all-day loads?

The modules run at the standard 1.1V JEDEC voltage with no heat spreader, so thermal output stays within normal DDR5 SODIMM limits for sustained use.

Will the CL42 latency at 5200MHz cause thermal throttling under continuous load?

CL42 at 5200MHz is the rated JEDEC timing; the kit draws 1.1V and has no spreader, so it operates within standard thermal envelopes for long sessions.

Do I need a Lenovo Legion Pro 5 16ARX8 or Pro 7 16ARX8H with free 262-pin slots for this 32GB kit?

Yes, the 2x16GB 262-pin SODIMM kit is validated for those two Legion models and requires two available DDR5 slots.
