8GB DDR4 2133MHz Desktop Module

This 8GB DDR4 module runs at 2133MHz with CL15 latency and 1.20V operation. It is built as a single 288-pin unbuffered DIMM using major brand chips. The stick is validated as a direct replacement for IBM-Lenovo part numbers 03T7467 and 4X70K09921. It targets desktop owners who need a straightforward capacity increase.

Standard voltage and unbuffered design

Operating at the DDR4 standard 1.20V, the module draws typical power for its class without requiring elevated voltage. The unbuffered layout avoids the extra register circuitry that adds latency and heat in registered DIMMs. Under normal desktop workloads the part runs within standard thermal limits and produces no audible noise because it has no moving parts.

Tested compatibility replaces guesswork

Each unit undergoes quality assurance testing before shipment to confirm reliable operation at the rated 2133MHz speed. The validation covers the specific IBM-Lenovo part numbers listed so buyers can match the module to their system without cross-referencing generic specifications. This testing step reduces the chance of a mismatch that would prevent the system from posting.

Questions about this item

How do I install the 288-pin DDR4 DIMM and which step is often missed?

Align the notch on the module with the slot key, press firmly until both retention clips click shut, then verify the BIOS reports 2133 MHz at 1.20 V.

What maintenance or replacement will this 8 GB module need later?

No scheduled maintenance is required; replace only if memory errors appear or a larger capacity is desired.

What limit appears first during sustained use of this CL15 1.20 V kit?

The JEDEC-standard 1.20 V voltage and CL15 latency define the thermal and timing ceiling under continuous load.
