SK hynix HMT425S6AFR6A-PB_UA 2GB DDR3 SO-DIMM 1600MHz 204-Pin

SKU CH-CV83-X1BJQ MPN HMT425S6AFR6A-PB_UA

A 2 GB DDR3 SO-DIMM laptop memory module running at 1600 MHz with CL11 latency and 1.35 V operation

  • 2 GB DDR3 SO-DIMM expands laptop memory
  • 1600 MHz PC3-12800 speed handles everyday workloads
  • CL11 latency and 1.35 V keep power draw low
  • 204-pin form factor fits standard DDR3 laptop slots
  • Single-rank 1Rx16 design simplifies compatibility

2 GB DDR3 SO-DIMM for laptop upgrades

This 2 GB DDR3 SO-DIMM runs at 1600 MHz with CL11 latency and 1.35 V operation. It fits 204-pin slots in notebooks that accept PC3-12800 memory. The single-rank 1Rx16 organisation keeps the module simple for basic capacity increases. Non-ECC design suits standard consumer laptops.

Low-voltage DDR3 runs cool and quiet

Operating at 1.35 V reduces heat output compared with 1.5 V DDR3 modules. The memory clock of 200 MHz and 1600 MHz data rate draw modest power during typical workloads. No active cooling is required on the module itself. Silent operation is inherent with no moving parts.

No extras included in the package

The module ships alone without cables, manuals or software utilities. Installation relies on the laptop’s own BIOS to detect and configure the memory at 1600 MHz CL11. Compatible part numbers PC3L-12800S-11-12-C3 and PC3L-12800S-11-13-C3 help verify fit before purchase.

Questions about this item

How do I install this 204-pin SO-DIMM and which notch alignment do people miss?

Align the key notch on the module with the slot ridge, insert at a 30-degree angle until the gold contacts disappear, then press down firmly until both side clips click. The 1.35V DDR3 stick fits standard laptop DDR3 sockets.

What maintenance or replacement will this 2GB DDR3 module need later?

No scheduled maintenance is required. If errors appear, reseat the module to clean oxidised contacts. Replace only if memory tests fail or capacity becomes insufficient for your workload.

What limit appears first under sustained use with this CL11 1600MHz module?

The 2GB capacity ceiling is reached before thermal or bandwidth limits. Heavy multitasking will trigger paging to storage, slowing the system well before the DDR3 chips throttle.
