8GB DDR4 DIMM for desktop upgrade

This 8GB DDR4 DIMM adds memory capacity to a desktop computer. It uses a 288-pin unbuffered layout and runs at the standard 1.2V. The module is built with major-brand chips and tested at 2133MHz with CL15 timing. It suits users who need a straightforward capacity increase for everyday workloads.

Capacity headroom at 2133MHz CL15

The single 8GB module handles typical office applications, web browsing and light multitasking without pressure. Heavier workloads such as video editing or large dataset processing will exhaust the 8GB limit and push the system into swap. The PC4-17000 rating sets the bandwidth ceiling for the 2133MHz data rate.

DDR4 2133MHz interface limits

The DDR4 2133MHz interface delivers a maximum transfer rate of PC4-17000. Latency is fixed at CL15 for this module, so timing cannot be tightened without stability risk. Voltage is locked at 1.20V, matching the DDR4 standard. Compatibility depends on the motherboard supporting DDR4 2133MHz unbuffered DIMMs.

Questions about this item

Will this 288-pin DDR4 module run at 1.20 V alongside older DDR4 sticks that also use 1.2 V?

Yes, the module operates at the standard 1.20 V DDR4 voltage, so it will match other 1.2 V DDR4 DIMMs in the same system.

How can I confirm the stick is running at the rated 2133 MHz CL15 after installation?

Check the memory speed and latency in the BIOS or with a tool such as CPU-Z; they should report 2133 MHz and CL15 timings.

Does the single 8 GB DIMM come alone or with extra parts such as a heatsink or screwdriver?

The package contains only the 1×8 GB DDR4 288-pin UDIMM; no heatsink, tools or additional accessories are included.
