Desktop Memory Upgrade

This 4GB DDR4 module runs at 2133MHz with a CL15 latency and operates at the standard 1.20V. It is an unbuffered, non-ECC DIMM built with major brand chips and intended for desktop systems that support this specification.

Simple DIMM Installation

The 288-pin DIMM fits into any compatible desktop slot and requires no special tools or configuration beyond seating the module firmly until the retention clips click. The most common issue is a mismatch between the system's supported speed or maximum capacity and this module's 2133MHz rating, so verifying the motherboard or OEM documentation first avoids a non-posting system.

DDR4 Platform Limits

DDR4 memory tops out at the standard 1.20V and the JEDEC-defined frequencies for this generation, meaning this 2133MHz module will not exceed that ceiling without manual overclocking which the platform may not allow. The 4GB capacity also restricts multitasking headroom on modern operating systems, so the practical limit is often the total number of slots the board provides rather than the memory standard itself.

Questions sur cet article

How do I confirm the 2133MHz CL15 module is running at its rated speed after installation?

Open Task Manager or CPU-Z and verify the memory tab shows 2133 MT/s with CAS latency 15 at 1.20 V.

What ships in the box and what must I source separately?

One 4 GB DDR4 288-pin UDIMM is included; no cables, brackets or additional modules are supplied.

Should I choose the 4X70G88312 or 4X70K09920 compatible version for my Lenovo desktop?

Both part numbers reference the same 4 GB DDR4 2133 CL15 specification; select whichever matches your service manual.
