8GB DDR4 2133MHz desktop module

This Timetec UDIMM adds 8GB of DDR4 memory to compatible desktop PCs and workstations. It runs at 2133MHz with CL15 latency and 1.2V operation. The 288-pin unbuffered non-ECC design fits standard desktop DIMM slots. Installation is plug-and-play with no expertise required.

DDR4 2133MHz speed and CL15 latency ceiling

The module operates at the base DDR4 2133MHz data rate with PC4-17000 bandwidth. CAS latency is fixed at CL15 for this speed grade. Voltage is set at 1.2V. The memory will downclock automatically if the system only supports lower frequencies. It cannot run faster than 2133MHz on this module.

Upgrade from DDR3 or lower capacity DDR4

Replaces older DDR3 modules that use higher voltage and lower bandwidth. Also upgrades systems running with less than 8GB of DDR4 memory. The jump is worthwhile when the motherboard supports DDR4 2133MHz and the workload needs more multitasking headroom. Not for laptops or SODIMM slots.

Questions about this item

Should I pick the 8 GB, 16 GB or 32 GB version of this Timetec DDR4 module?

Choose the capacity that matches your motherboard's maximum per slot and the total RAM you want; this listing is the single 8 GB stick, while 16 GB and 32 GB modules are also offered in the same DDR4 2133 MHz CL15 1.2 V UDIMM family.

What does the 2133 MHz rating deliver once the stick is installed in my desktop?

The module runs at 2133 MT/s with CL15 latency at 1.2 V, giving a PC4-17000 bandwidth ceiling that the memory controller will use automatically if the board supports that speed.

How does the 288-pin DDR4 UDIMM interface limit what I can use this memory with?

The 288-pin unbuffered non-ECC DDR4 form factor fits only desktop DIMM slots that accept DDR4 UDIMM modules; it will not work in laptop SODIMM sockets or in boards that require registered or ECC memory.
