64GB DDR4 kit for HP Z workstations

This 64GB kit contains four 16GB DDR4 2666MHz DIMMs built for HP Z1 G5, Z2 SFF G4 and Z2 Tower G4 workstations. The modules run at 1.2V with CL19 timings and are unbuffered non-ECC. They fill all four memory slots in the supported systems.

Suits owners of the listed HP workstations needing

Builders who need ECC error correction, registered modules, speeds above 2666MHz or a different form factor should look elsewhere. The kit is not compatible with laptops, consumer desktops or servers that require registered memory.

Four matched sticks enable quad-channel operation

Installing the full set lets the workstation run in quad-channel mode for maximum bandwidth. All modules come from Computer Memory Solutions and are tested together to avoid mixed-kit timing issues.

Perguntas sobre este artigo

Does my HP Z2 SFF G4 need four empty 288-pin slots to install this 64GB kit?

Yes, the kit contains four 16GB DIMMs and the Z2 SFF G4 provides four DDR4 slots, so all four must be free for a full 64GB installation.

If I keep two 16GB 2666MHz sticks already in my Z2 Tower G4, will this kit run at CL19 alongside them?

All modules will operate at the slowest installed speed and timing; mixing with existing CL19 2666MHz sticks keeps the kit at its rated CL19, but any slower modules would reduce overall performance.

How can I confirm the system recognises all 64GB at 2666MHz after fitting the four DIMMs?

Boot into a 64-bit OS, open Task Manager or BIOS and verify the total shows 64GB running at 2666MHz with timings reported as 19-19-19.
