4GB DDR3 1600MHz Desktop Upgrade

This single 4GB DDR3 module runs at 1600MHz with CL11 latency and standard 1.50V operation. It is an unbuffered non-ECC DIMM built for desktop systems needing a straightforward capacity increase. The 240-pin form factor fits typical DDR3 motherboard slots without extra configuration.

Standard voltage and no heat spreader

Operating at the JEDEC 1.50V level, the module draws the same power as stock DDR3 parts and produces no more heat than the original equipment. Without a heat spreader the profile stays low, so airflow from the CPU cooler passes freely over the chips. Acoustic impact is zero because the memory has no moving parts.

Replaces listed Corsair DDR3 kits

The module is validated as a compatible equivalent for Corsair CMY8GX3M2A1600C9R, CMZ12GX3M3A1600C9, CMX8GX3M2A1600C11, CMX8GX3M2A1600C9 and CMX8GX3M2B1600C9. Swapping a failed stick or adding one 4GB unit to an empty slot restores dual-channel bandwidth when paired with an identical module. The upgrade makes sense when the system still uses DDR3 and the board supports 1600MHz CL11 timing.

Questions about this item

How do I install this 240-pin DDR3 DIMM and what step do people get wrong?

Power off the PC, open the case, align the notch on the 240-pin module with the slot key, press down firmly until both side clips click, then power on; the step people miss is pushing hard enough to seat both clips fully.

What maintenance or replacement will this 1.5 V DDR3 module need later?

No routine maintenance is required; if errors appear years later, run a memory test and replace the module if it fails, otherwise it runs for the life of the system.

What limit shows up first on this CL11 1600 MHz kit under sustained load?

The CL11 latency at 1600 MHz sets the bandwidth ceiling; under heavy sustained use the memory controller hits that timing limit before voltage or temperature become factors.
