8GB DDR3 1866MHz desktop module

This A-Tech module provides eight gigabytes of DDR3 memory at 1866MHz with CL13 latency. It is an unbuffered non-ECC DIMM that runs at the standard 1.5V. The stick is built as a direct replacement for Corsair CMZ32GX3M4X1866C10R and CMZ32GX3M4A1866C9 kits. It targets owners of older desktops that still use DDR3 platforms.

240-pin DIMM without heat spreader

The module uses a standard 240-pin DDR3 DIMM edge connector, so it fits any desktop board with DDR3 slots. No heat spreader is fitted, keeping the profile low for tight spaces or large CPU coolers. Major-brand chips are used and every unit is tested before shipping. The bare PCB design also makes visual inspection simple.

Replaces Corsair CMZ32GX3M4X1866C10R

This single 8GB stick substitutes for one module from those 32GB Corsair quad-channel kits. The rated speed is 1866MHz PC3-14900 with CL13 timing at 1.5V. The upgrade is worth it when a system needs more capacity or a failed stick must be swapped without changing the remaining modules.

Questions about this item

Does the DDR3 1866 PC3-14900 module run at 1866 MHz out of the box?

The module is tested at 1866 MHz with a CAS latency of CL13 and operates at the standard 1.5 V for DDR3.

Will this 240-pin DIMM fit a standard desktop DDR3 slot?

The stick uses the 240-pin DDR3 DIMM form factor and is an unbuffered non-ECC module designed for desktop motherboards.

Do I need to enable XMP in the BIOS to reach the rated speed?

Install the DIMM firmly until the retention clips click, then enter the BIOS and select the 1866 MHz profile or set frequency manually to 1866 MHz.
