Our take on the Axiom DDR5 module 16 GB SO-DIMM 262-pin 5600 MHz PC5-44800 CL46 1.1 V for HP EliteBook 840 G10 845 G10 860 G10 865 G10 ZBook Firefly 14 G10

A single 16 GB DDR5 SO-DIMM rated at 5600 MHz (PC5-44800) with CL46 timings at 1.1 V, built by Axiom as a system-specific module for HP EliteBook 840/845/860/865 G10 and ZBook Firefly 14 G10 laptops. It is a plain non-ECC, unregistered module with no heat spreader and no RGB. The point of it is fit and compatibility rather than speed: it matches the 262-pin DDR5 slot and the JEDEC profile those HP machines expect, so it drops in without BIOS complaints. Against generic DDR5-5600 SO-DIMMs it costs more for the same silicon, but it is the safer pick if you want a module that is explicitly validated for your EliteBook or Firefly.

Pros
  • Rated 5600 MHz at CL46, the standard JEDEC speed for these HP platforms
  • 1.1 V DDR5, so it runs cool and within laptop power budgets
  • Explicitly listed for EliteBook 840/845/860/865 G10 and ZBook Firefly 14 G10
  • Single 16 GB module leaves the second slot free for a later upgrade
  • No RGB or tall heat spreader to foul a thin laptop chassis
Cons
  • Non-ECC and unregistered, so no error correction for data integrity
  • CL46 latency is loose compared with premium gaming SO-DIMMs
  • No XMP, so there is nothing to tune beyond the JEDEC profile
  • Axiom branding carries a premium over equivalent generic modules
  • Single stick means single-channel until you add a second module

Questions and answers

Will this work in my EliteBook 840 G10?
Yes. It is listed for the EliteBook 840, 845, 860 and 865 G10 and the ZBook Firefly 14 G10, and uses the 262-pin DDR5 SO-DIMM slot those models have.
Is it faster than the 4800 MHz memory my laptop came with?
It runs at 5600 MHz, which is the higher JEDEC speed these platforms support. Real-world gains are modest, mostly in memory-heavy work like many browser tabs or large spreadsheets.
Can I add a second 16 GB module later?
Yes, provided your model has a free SO-DIMM slot. Matching it with an identical 16 GB DDR5-5600 module gives you dual-channel bandwidth.
Does it have ECC or RGB lighting?
No to both. It is a non-ECC, unregistered module with no lighting, which is what laptops in this class expect.
Is CL46 a problem for gaming?
Not much. Laptop DDR5 at 5600 MHz is JEDEC-specified at CL46, and the integrated graphics benefit more from dual-channel operation than from tighter timings.
