4GB DDR3 1866 desktop module

This A-Tech module adds four gigabytes of DDR3 memory to a desktop system. It is built as a direct replacement for several G.Skill F3-14900 series kits. The single stick fits a standard 240-pin DIMM slot and runs at the standard 1.5 volt level.

CAS latency 13 at rated speed

The module operates at 1866 MHz with a CAS latency of 13 cycles. This timing figure determines whether the stick matches the memory controller requirements of the target motherboard. Verify that the platform supports CL13 at this frequency before installation.

Steady throughput without heat spreader

Without a heat spreader the module relies on case airflow to dissipate heat during extended workloads. Sustained bandwidth remains consistent as long as the chassis provides adequate ventilation across the bare circuit board.

Questions about this item

Will this module fit a motherboard that only accepts DDR3 240-pin DIMMs?

The module is a DDR3 240-pin DIMM, so it fits any desktop board with a standard DDR3 DIMM slot.

Can I mix this CL13 stick with existing CL9 memory running at 1866 MHz?

Mixing different CAS latencies works; the system will run all modules at the slowest timing, here CL13.

Does the 1.5 V rating match the standard DDR3 voltage my board expects?

Yes, 1.5 V is the standard DDR3 operating voltage and matches what DDR3 desktop boards require.
