Product identity

The VisionTek 900451 is a 4GB DDR3 SO-DIMM module rated at 1600MHz with CAS latency 9 and 1.50V operation. It uses a 204-pin form factor designed for laptop memory slots.

Who this suits and who should look elsewhere

This module suits owners of laptops that accept DDR3 SO-DIMM memory running at 1600MHz and 1.50V. Buyers whose notebooks require a different memory generation, a different pin count, or a lower operating voltage cannot use this part.

The specification that decides fit

The 204-pin DDR3 SO-DIMM interface at 1600MHz (PC3-12800) with 1.50V and CL9 timing is the single specification that determines whether this module will install and function in a given laptop.

Questions about this item

Does the 1.5 V DDR3-1600 module run hot or draw much power during all-day use?

The module operates at the standard 1.5 V for DDR3 and carries a CL9 latency rating, which together indicate typical power draw and heat output for this class of memory.

What must my laptop already have for this 204-pin SO-DIMM to work?

Your laptop needs a free 204-pin DDR3 SO-DIMM slot that supports 1600 MHz (PC3-12800) unbuffered, non-ECC memory at 1.5 V.

Will this CL9 1600 MHz stick work alongside slower DDR3 modules I keep installed?

Yes, the system will run all modules at the speed and timings of the slowest stick, so your existing memory remains usable.
