32GB DDR4 2666 Kit for ZBook Workstations

This 32GB kit contains two 16GB DDR4 2666 SO-DIMM modules built for HP ZBook 15 G5, 15 G6 and 17 G6 mobile workstations. It targets professionals who need reliable memory upgrades for supported Intel Core i9, i7 or i5 configurations. The unbuffered, non-ECC design matches the requirements of those specific processor families.

DDR4 SO-DIMM speed and capacity ceiling

The DDR4 2666 interface limits each module to 2666 MT/s and the system caps total memory at 128GB across four sockets. Mixing modules forces all memory to run at the slowest installed speed or the processor capability. A 64-bit operating system is required to address more than 4GB of memory.

Non-ECC requirement for Core processors

Intel Xeon processors in these workstations require ECC UDIMM memory, so this non-ECC kit will not work with Xeon configurations. Buyers with Xeon-based ZBook models must choose ECC modules instead.

Questions about this item

Should I pick the 32GB kit or a smaller capacity for my ZBook 15 G6?

The kit provides 32GB total in two 16GB modules; the ZBook 15 G5, G6 and ZBook 17 G6 support up to 128GB across four sockets, so you can add another matched pair later if you need more.

What does the DDR4 2666 rating mean for everyday workloads on these workstations?

The modules run at 2666 MHz (PC4-21300) with CL19 timing; the system will operate at the slowest installed module or the processor's supported speed, so performance matches the CPU's memory controller limit.

Will the 260-pin SO-DIMM fit and run at full speed in my ZBook 17 G6?

Yes, the 260-pin DDR4 SO-DIMM form factor matches the ZBook 15 G5, G6 and 17 G6 slots; the kit is unbuffered non-ECC at 1.2V, which is the correct type for Core i5/i7/i9 processors in these models.
