HP Z600 triple-channel kit

This 24 GB kit contains three 8 GB registered ECC DIMMs built for the HP Workstation Z600. It targets administrators upgrading dual-CPU servers that require registered memory and triple-channel interleaving across all six slots.

240-pin registered installation

Modules are standard 240-pin DDR3 DIMMs that seat in the Z600’s three-channel banks; registered buffers add a slight insertion force but otherwise install like regular DIMMs. The board must carry the C2 revision of the Intel 5520 chipset, otherwise registered DIMMs will not be recognised. Mixing registered and unbuffered ECC in the same bank prevents boot, and x4 versus x8 DRAM variants must not share a channel.

Sustained server workloads

Rated at 1333 MHz with CL9 timings and 1.5 V, the kit delivers steady bandwidth across all three channels during long compute runs. Registered buffering reduces electrical load on the memory controller, helping stability when all six sockets are populated up to the 48 GB dual-CPU maximum. Unbuffered ECC cannot match this density on the same platform.

Questions about this item

How can I confirm the kit is running in triple-channel mode at 1333 MHz after installation?

Enter the system BIOS and verify that all 24 GB are detected and the memory speed reads 1333 MHz with triple-channel interleaving enabled.

What items are included in the box and is anything else needed for installation?

The package contains three 8 GB DDR3 240-pin registered ECC DIMMs; no extra parts are required if the workstation has available DIMM slots.

Which version of the 8 GB registered ECC module should I choose for the Z600 — the x4 or x8 DRAM variant?

This kit uses 2Rx4 (x4) organisation; for triple-channel operation install three matching x4 modules in the same bank.
