HP Z4 G6i Workstation

This HP Z4 G6i workstation is a new tower desktop built for professional workloads that demand ECC memory and vPro manageability. It ships with Windows 11 Pro, an English keyboard and a mouse included in the box. The air-cooled chassis uses a 1200 W power supply to support sustained compute tasks.

Intel Xeon 636 with 48 MB L3 cache

The single installed processor is an Intel Xeon 636 running at a 3.50 GHz base frequency with 48 MB of L3 cache. It uses the LGA-4710 socket on the Intel W890 chipset and supports vPro Technology plus ECC memory. Only one CPU can be fitted, so the 64 GB DDR5 ECC registered configuration (2 x 32 GB) occupies two of the eight available DIMM slots.

Tool-less tower access and DDR5 ECC modules

The tower chassis provides tool-less entry for memory and storage upgrades, while the 1 TB PCIe NVMe 4.0 x4 SSD occupies one M.2 slot. Installers must use DDR5 ECC registered DIMMs; non-ECC or older DDR generations will not function. The 10 USB ports include one USB 2.0, one USB 3.0 and one USB Type-C 10Gbps connector alongside a single Gigabit Ethernet port.

Questions about this item

Will the 3.50 GHz Xeon 636 clock stay high under sustained multi-core load in a tower chassis?

The 1200 W power supply and air cooler in this tower are sized to support the Xeon 636 at its 3.50 GHz base frequency during extended workloads.

What does the PCIe 4.0 x4 link mean for the 1 TB SSD in daily use?

The NVMe drive connects through a PCIe 4.0 x4 interface, so sequential read and write speeds can reach the drive's rated ceiling without bus bottleneck.

How many memory slots remain free for expanding the 64 GB DDR5 ECC configuration?

Two of the eight DDR5 slots are occupied by the factory 2 x 32 GB modules, leaving six slots open for registered ECC memory up to 512 GB total.
