4GB DDR3 1600MHz CL11 Desktop Module

This 4GB DDR3 DIMM runs at 1600MHz with a CAS latency of 11 and a standard 1.5V supply. It is an unbuffered, non-ECC module built for desktop systems that accept 240-pin DDR3 memory.

Sustained-load behaviour

The module operates at the JEDEC-standard 1.5V, so power draw and thermals remain stable during extended workloads. CL11 timing at 1600MHz delivers consistent throughput for everyday multitasking and background tasks without voltage scaling.

Replaces Corsair CMP12GX3M3A1600C9 series

It serves as a direct replacement for Corsair part numbers CMP12GX3M3A1600C9, CML8GX3M2A1600C9, CML8GX3M2A1600C9B, CML4GX3M1A1600C9 and CML16GX3M4A1600C9. The upgrade is worthwhile when a system needs additional DDR3 capacity or a faulty original module must be swapped.

Questions about this item

How much power does this 4GB DDR3 1600MHz CL11 module draw when running continuously at 1.5V?

The module operates at the standard DDR3 voltage of 1.5V, drawing minimal power typical for a 4GB unbuffered DIMM at this speed and latency.

Does my motherboard need a 240-pin DDR3 slot to install this 4GB 1600MHz CL11 stick?

Yes, this is a 240-pin DDR3 DIMM, so the board must provide a standard DDR3 desktop memory slot for it to fit and function.

Will this CL11 1.5V DDR3 1600MHz module work alongside my existing Corsair CML8GX3M2A1600C9 sticks?

It is listed as a compatible replacement for that exact Corsair part number, matching 1600MHz speed and 1.5V voltage, though CAS latency differs at CL11 versus CL9.
