Questions about this item

What does the 2133MHz speed mean once this module is installed in my HP ENVY Phoenix?

The module runs at 2133MHz, matching the DDR4-2133 JEDEC standard. Your system will operate the memory at this frequency, delivering the rated PC4-17000 bandwidth for everyday workloads.

How does the PC4-17000 rating limit real-world throughput?

PC4-17000 denotes a peak transfer rate of 17000 MB/s. Actual throughput depends on the memory controller and workload, but the module cannot exceed this JEDEC-defined ceiling.

Will the 288-pin UDIMM fit the DIMM slots on my HP ENVY Phoenix 860-005nf?

Yes. The 288-pin unbuffered DIMM matches the desktop DDR4 slot layout used by the listed HP ENVY Phoenix models, so it seats directly without adapters.
