16GB DDR4 2133MHz Desktop Module

This 16GB DDR4 DIMM operates at 2133MHz with CL15 latency and 1.2V standard voltage. It uses a 288-pin unbuffered non-ECC design built with major brand chips. The single module suits desktop systems that accept DDR4 2133 memory.

Replaces Kingston KVR21N15D8/16 and HX421C14FBK2/32

The module is tested as a direct equivalent for several Kingston part numbers including KVR21N15D8/16, HX421C14FBK4/64, KVR21N15D8K2/32, HX421C14FBK2/32 and KCP421ND8/16. Each unit undergoes quality assurance testing for dependable performance.

Suits DDR4 2133 desktop upgrades only

This memory fits desktops that support DDR4 2133MHz unbuffered non-ECC DIMMs. Systems requiring ECC, registered modules, or different DDR generations will not accept it. Verify your platform specifications before purchase.

Questions about this item

Does this 16GB DDR4 module need any firmware updates or periodic cleaning to keep running reliably?

No firmware updates are required for this unbuffered DIMM; it operates at standard 1.2V with major-brand chips and only needs occasional dust removal from the 288-pin contacts.

What limit appears first when this CL15 2133MHz kit runs at full load for hours?

The memory controller's maximum supported frequency of 2133 MHz is the hard ceiling; latency stays at CL15 and voltage remains at 1.20V, so no further throttling occurs.

How much heat and noise does this single 16GB stick produce during all-day operation?

It runs silently with no moving parts; at 1.2V the thermal output is low enough that standard case airflow keeps temperatures well within normal DDR4 limits.
