Capacity and fit

This 4 GB DDR4 module uses the 288-pin DIMM form factor and runs at 2133 MHz with CL15 latency. It is an unbuffered non-ECC stick rated at 1.2 V, built as a direct replacement for HP part numbers 798033-001, 834931-001 and T0E50AA. The single-rank layout suits mainstream desktop boards that accept standard DDR4 memory.

Thermals and power

At the standard 1.2 V DDR4 voltage the module draws minimal power and produces little heat during typical desktop workloads. No active cooling is required because the low-density 4 GB design stays well within normal operating temperatures. Silent operation is assured as there are no moving parts on the memory itself.

Sustained workload behaviour

Under continuous multitasking or extended background tasks the stick maintains its rated 2133 MHz speed without throttling. The major-brand chips and factory testing provide stable timing at CL15 across long sessions. Error-free operation is supported by the unbuffered architecture and standard voltage level.

Questions about this item

How do I install this DDR4 DIMM and which step do people often miss?

Align the notch on the 288-pin module with the slot key, press firmly until both retention clips click, then verify the system recognises the full 4GB at 2133MHz in BIOS.

What maintenance or replacement will this 4GB DDR4 2133MHz CL15 module need later?

No routine maintenance is required; keep the contacts dust-free and replace the stick only if memory errors appear or a capacity upgrade is desired.

What limit appears first when this 1.2V unbuffered DIMM runs under sustained load?

The CL15 latency at 2133MHz sets the throughput ceiling before voltage or thermal constraints become a factor.
