Simmtec 4GB DDR4 2133 UDIMM

This is a 4GB DDR4 desktop memory module rated at 2133 MHz with a CAS latency of CL15. It uses a single-rank 1R8 organisation and the standard 288-pin UDIMM form factor operating at 1.2 V.

Home and office PCs needing a basic upgrade

The module suits older DDR4 platforms that officially support 2133 MHz speeds. Systems requiring ECC error correction, registered signalling or higher capacities per slot cannot use this stick.

2133 MHz DDR4 speed rating

The 2133 MHz PC4-17000 specification is the single figure that decides compatibility. A motherboard and CPU memory controller must both list 2133 MHz support for the RAM to run at its rated frequency.

Questions about this item

What does the 2133MHz rating mean once the module is installed in a desktop?

The module will run at 2133MHz with CL15 latency, delivering PC4-17000 bandwidth for standard desktop workloads.

How does the DDR4 288-pin UDIMM interface limit performance in practice?

The 288-pin UDIMM slot caps the module at 2133MHz and 1.2V, so it cannot exceed the rated PC4-17000 speed.

What physical space does the 288-pin UDIMM stick need to fit and mount?

It requires a standard desktop DDR4 DIMM slot and clearance for a 288-pin unbuffered module.
