64GB DDR4 SODIMM kit for HP Zbook

This 64GB kit contains four 16GB DDR4 2400MHz SODIMM modules built for HP Zbook Mobile Workstation 15 G3, 15 G4, 17 G3 and 17 G4. The unbuffered, non-ECC sticks run at 1.2V with CL17 timing and use major-brand chips. Computer Memory Solutions guarantees compatibility with the listed part numbers.

DDR4 2400MHz SO-DIMM practical limits

DDR4 2400 (PC4 19200) is the maximum speed these workstations accept; faster modules will down-clock to this rate. The 260-pin SO-DIMM form factor fits only laptop and mobile-workstation slots, not desktop DIMM sockets. Four ranks of 2Rx8 organisation fill all four memory channels on supported models.

Upgrading from lower-capacity DDR4 SODIMMs

This kit replaces smaller or slower DDR4 SODIMM sets when the workload needs the full 64GB ceiling these Zbooks allow. The jump is worth it for virtualisation, large datasets or multi-application workflows that exceed 32GB. Buyers staying at 32GB or below, or using systems limited to two slots, will not benefit.

Questions about this item

Should I choose the 64GB kit or a smaller capacity for my ZBook?

The kit provides 64GB (4 x 16GB) which matches the maximum supported memory and fills all four SODIMM slots in the ZBook 15 G3, 15 G4, 17 G3 and 17 G4.

What does the 2400MHz rating mean for actual performance in these workstations?

The modules run at DDR4 2400 with CL17 timing (17-17-17) at 1.2V, delivering the standard JEDEC speed these ZBook models are designed to use.

Does the PC4-19200 designation affect compatibility with the 260-pin SODIMM slot?

PC4-19200 is the bandwidth label for DDR4 2400; the kit uses standard 260-pin unbuffered non-ECC SODIMMs that fit the ZBook slots directly.
