HP Z1 All-in-One 16 GB kit

This 16 GB kit contains two 8 GB DDR3 ECC non-registered DIMMs built for the HP Compaq Workstation Z1 All-in-One. Each module runs at 1600 MHz with CL11 timing at 1.5 V. The 240-pin design matches the system's four memory slots. Computer Memory Solutions guarantees compatibility with the listed Z1 models.

For Z1 owners needing ECC memory

The kit suits owners of B2B85UT or B2B84UT Z1 workstations who want the full 16 GB ECC capacity in matched pairs for dual-channel operation. Buyers whose Z1 runs a Core i5 or i7 processor cannot use ECC modules; those systems only accept non-ECC memory. Mixing ECC with non-ECC is not supported on this platform.

Must install in matched pairs

The Z1 requires modules to be ordered and installed in pairs to enable dual-channel mode. This 2 x 8 GB kit satisfies that rule and delivers the maximum 16 GB ECC unbuffered capacity the system recognises. A 64-bit operating system is required to address the full amount.

Questions about this item

Does the DDR3-1600 (PC3-12800) interface limit the modules to 1600 MHz even if the workstation supports higher speeds?

Yes, the kit is rated for DDR3-1600 (PC3-12800) and will run at that speed; the system will not exceed the module rating.

Will these 240-pin DIMMs fit the HP/Compaq Workstation Z1 All-in-One, and how many slots does that system provide?

The 240-pin form factor matches the Z1 All-in-One, which has four memory sockets for dual-channel pairs.

The spec sheet says modules must be installed in pairs — which slots should the two 8 GB sticks occupy for dual-channel operation?

Populate the two slots of the same channel pair (typically slots 1 and 3 or 2 and 4) so the kit runs in dual-channel mode.
