4GB DDR4 2133 DIMM for compatible systems

This 4GB DDR4 2133 DIMM is built for desktops and workstations that accept unbuffered non-ECC memory. It installs in a standard 288-pin slot and runs at 1.2V. The module suits users adding a single stick to a supported platform. Buyers who need ECC or registered memory should select a different module.

Standard voltage and unbuffered design

The stick operates at the standard DDR4 voltage of 1.2V with no additional cooling required. Unbuffered construction keeps the electrical load low for the memory controller. Typical power draw stays within normal DDR4 limits for a 4GB density. Noise is not a factor because the module has no moving parts.

Single rank 2Rx8 organisation at CL15

This module uses a 2Rx8 rank configuration with CAS latency 15 and 15-15-15 timings. The rank layout determines how the memory controller addresses the chips and can affect compatibility with certain chipsets. Verify that your system supports 2Rx8 unbuffered DIMMs before purchase.

Questions about this item

How do I install this 288-pin DDR4 DIMM and what step is commonly missed?

Align the notch with the slot key, press down firmly until both side clips click shut, then verify in BIOS that the module runs at 2133 MHz with CL15 timing.

What maintenance or replacement will this 4 GB module need over time?

No routine maintenance is required; if errors appear, the limited lifetime warranty from Computer Memory Solutions covers exchange or repair for manufacturing defects.

What limit appears first when this CL15 1.2 V kit runs sustained workloads?

The single 4 GB capacity and 2133 MT/s bandwidth become the bottleneck before voltage or thermal limits are reached.
