A-Tech 4GB DDR4 2133MHz CL15 1.2V HP 798033-001 834931-001 T0E50AA Desktop RAM

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.
