16GB DDR3L 1600 Desktop Module

The Crucial CT204864BD160B is a 16GB unbuffered DIMM running at DDR3L 1600 with CL11 latency. It operates at 1.35V and uses Micron chips without a heat spreader. The module targets enthusiasts building high-performance or gaming desktops that require this specific density and voltage.

Upgrading from lower-density DDR3L kits

This single 16GB stick replaces smaller-capacity DDR3L modules to increase total system memory. The jump is worthwhile when applications exceed current RAM limits or when a quad-channel configuration is desired using matching modules. It does not serve systems limited to lower maximum densities per slot or those requiring registered or ECC memory.

Verify motherboard DDR3L support and slot limits

Confirm the motherboard accepts DDR3L 1.35V unbuffered non-ECC UDIMMs and supports 16GB per slot. Check the qualified vendor list for compatibility with this density and CL11 timing. Ensure the CPU memory controller can address the total capacity planned and that physical clearance exists for the module height.

Questions about this item

Is this module compatible with a desktop motherboard that requires DDR3L 1600 memory?

Yes, the module is built to the DDR3L 1600 standard, so it fits desktop boards that specify that speed.

Can I install this 16GB stick alongside my existing 1.35V DDR3L modules?

Yes, it operates at 1.35V and is unbuffered non‑ECC, matching the voltage and signal type of standard DDR3L DIMMs.

What do the CL11 and PC3L 12800 labels mean for real‑world use?

CL11 is the CAS latency timing at 1600 MT/s, and PC3L 12800 is the peak bandwidth rating; together they describe the module's rated speed and responsiveness.
