8GB DDR3 1866MHz Desktop Module

This 8GB DDR3 DIMM runs at 1866MHz with CL13 latency and 1.5V operation. It is an unbuffered non-ECC module built for standard desktop systems. The 240-pin form factor fits typical DDR3 motherboard slots.

Drop-in Corsair replacement

The module matches the specifications of Corsair part numbers CML32GX3M4A1866C10, CMD16GX3M2A1866C9, CMY16GX3M2A1866C9R, CMZ16GX3M2A1866C10 and CMZ32GX3M4X1866C10. It installs directly into existing DDR3 slots without BIOS changes. The single 8GB stick leaves remaining slots free for future expansion.

Upgrade from lower-capacity kits

Replacing 4GB or 8GB kits with this 8GB module doubles usable memory in many builds. The jump is worthwhile when multitasking or running memory-intensive applications that exceed current capacity. The 1866MHz speed maintains parity with existing DDR3 1866 configurations.

Questions about this item

Will the CL13 latency cause a bottleneck during sustained heavy workloads?

CL13 is the rated CAS latency at 1866 MHz; it determines the access delay for each request and does not change with sustained use.

How much heat or extra power does an 8 GB DDR3 1866 MHz 1.5 V module add when running all day?

The module operates at the standard 1.5 V DDR3 voltage with no heat spreader, so thermal output and power draw remain at typical DDR3 levels for continuous operation.

What motherboard slot is required for this 240-pin DDR3 DIMM to work?

A desktop motherboard with a DDR3 240-pin DIMM slot supporting 1866 MHz (PC3-14900) unbuffered non-ECC memory is required.
