Capacity 64GB (4 x 16GB)

  • 64GB total capacity with four 16GB modules for heavy multitasking
  • DDR5 5200 speed rated at PC5-41600 for fast data throughput
  • CL42 CAS latency balances timing with standard voltage operation
  • 1V low-voltage design reduces power draw in laptops and all-in-ones
  • 262-pin SODIMM form factor fits compatible notebook and NAS slots

64GB DDR5 5200 SODIMM kit

This 64GB kit contains four 16GB DDR5 5200 SO-DIMM modules rated at CL42 and 1.1V. It targets laptops, all-in-one desktops and compatible NAS appliances that accept 262-pin unbuffered non-ECC memory. The kit is sold new and complies with JEDEC and RoHS standards.

Four matched modules enable dual-channel

Supplying four identical 1Rx8 modules lets a two-channel controller populate both channels with a matched pair per channel. This arrangement avoids mixing different ranks or speeds, which can force the memory controller to run at a lower data rate or looser timings.

DDR5 5200 speed and CL42 latency

The modules operate at the JEDEC-standard 5200 MT/s with a CAS latency of 42 cycles. Systems that only support lower DDR5 speeds will down-clock the kit automatically, while platforms requiring higher frequencies or lower latencies will not reach their specified performance ceiling with these modules.

Questions about this item

Will the 262-pin SODIMM modules need any maintenance or replacement over time?

DDR5 SODIMM memory has no moving parts and requires no scheduled maintenance. The modules are built to JEDEC standards and carry a limited lifetime warranty, so replacement is only needed if a defect appears.

What is the first limit reached under sustained heavy workloads with CL42 latency?

The CAS latency of CL42 at 5200 MT/s sets the timing floor; under continuous load the memory controller will hit this latency ceiling before bandwidth or voltage limits become a factor.

How much heat and power do the 1.1 V modules produce when running all day?

Each 16 GB module operates at 1.1 V without a heat spreader, so power draw stays low and thermals remain within normal laptop cooling capacity during extended use.
