16GB DDR5 UDIMM for HP Z2 G9

This 16GB DDR5 4800 module is built for the HP Z2 G9 Tower Workstation. It targets IT professionals and system builders who need a validated memory upgrade for that specific platform. The unbuffered non-ECC design matches the workstation's desktop-class memory architecture.

CL40 latency at 1.1V

The CAS latency of CL40 at 1.1V is the decisive timing parameter for this module. It determines whether the memory meets the Z2 G9's qualified vendor list requirements. Systems that demand a different latency or voltage will not accept this part.

Single 1Rx8 module, no spreader

The kit contains one 1Rx8 UDIMM without a heat spreader. This keeps the profile low for dense workstation chassis but offers no thermal headroom for overclocking. Buyers who want RGB lighting or passive cooling fins must look elsewhere.

Questions about this item

What does the DDR5 4800 speed mean for real-world throughput in my workstation?

The module runs at 4800 MT/s, delivering the standard PC5-38400 data rate for DDR5 platforms that support this JEDEC speed.

How does the PC5-38400 rating translate to the memory bus in practice?

PC5-38400 is the JEDEC designation for DDR5-4800, so the memory controller will operate at 4800 MT/s on a compatible motherboard.

Will the 288-pin UDIMM fit my HP Z2 G9 tower without clearance issues?

Yes, it uses the standard 288-pin DDR5 UDIMM form factor with no heat spreader, matching the slot layout of the Z2 G9.
