4GB DDR3 1866MHz Desktop Memory
This A-Tech module is a 4GB DDR3 DIMM rated at 1866MHz with CL13 latency and 1.5V operation. It is built as an unbuffered, non-ECC stick using major-brand chips and ships without a heat spreader. The 240-pin form factor fits standard desktop memory slots.
Suits owners of Corsair CMZ8GX3M2A1866C9 kits
The module is tested as a direct replacement for Corsair part numbers CMZ8GX3M2A1866C9, CMZ8GX3M2A1866C9B and CMZ8GX3M2A1866C9R. Systems requiring registered memory, ECC functionality or a different pin count should consider other options. Buyers should confirm their motherboard supports DDR3 1866MHz before ordering.
CL13 CAS latency at 1.5V
The rated CAS latency of CL13 at the standard 1.5V DDR3 voltage determines whether the memory matches the timing requirements of the target system. This single figure governs compatibility with the original Corsair specification.

Questions about this item
Does the 240-pin DDR3 DIMM fit my desktop motherboard slot?
This module is a standard 240-pin DDR3 DIMM, the physical form factor used by desktop motherboards that support DDR3 memory.
What is the correct way to seat the module so the 1.5V contacts make full connection?
Align the notch on the module with the key in the slot, press down firmly until both side clips click into place, and verify the module sits evenly without tilting.
Will the lack of a heat spreader on this 1866MHz CL13 stick affect long-term reliability?
The module runs at standard 1.5V without a heat spreader; adequate case airflow is sufficient for normal desktop operation and long-term reliability.
