Single 4 GB DDR3 1600 UDIMM

This 4 GB unbuffered DDR3 module runs at 1600 MT/s with CL11 latency and 1.35 V operation. It targets owners of older desktop platforms that still use DDR3 memory and need a modest capacity increase for everyday multitasking.

Standard 240-pin DIMM installation

The stick inserts into any desktop DDR3 slot keyed for 1.35 V or 1.5 V operation; the system will train at the highest mutually supported speed. Problems usually appear when mixing kits with different densities or timings, which can prevent the board from posting.

4 GB single-rank capacity

The 1Rx8 layout provides 4 GB of addressable memory, enough for light office work, web browsing and older games. Headroom disappears quickly with modern browsers, virtual machines or large media files, so systems that regularly exceed 4 GB in use will see swapping and slowdown.

Questions about this item

Will this 1.35 V DDR3 module work in a motherboard that only supports 1.5 V memory?

The module is rated at 1.35 V; many DDR3 boards accept both voltages, but you should check the motherboard manual or CPU memory-controller specification to confirm 1.35 V support before buying.

My system has two slots — can I add this 4 GB stick alongside an existing 4 GB module for dual-channel?

Yes, if the existing stick is also DDR3 1600 CL11 1.35 V unbuffered non-ECC, the pair will run in dual-channel; mismatched speed, latency or voltage will force the system to the slowest common settings.

Does the 1Rx8 (dual-rank) organisation affect compatibility with my CPU’s memory controller?

Dual-rank 1Rx8 modules are standard for consumer DDR3; most desktop memory controllers support them without issue, but verify the maximum rank-per-channel limit in your CPU or motherboard documentation.
