HP Z4 G4 Workstation Motherboard – LGA2066, Intel Core X, DDR4 – L12125-001 L09990-001

Alright, here’s what we got — a used HP Z4 G4 motherboard, pulled from a working system and tested.

It's got the LGA2066 socket, so it's ready for Intel Core X series processors.

You get 8 memory slots running DDR4 SDRAM, and it's packed with expansion: two PCIe 3.0 x16 slots, two x4 slots, and one x8.

Plus you’ve got USB 3.0, Ethernet, PS/2, and SATA III onboard.

Multi-GPU?

Yep.

On-board audio?

You bet.

This board comes with a 30-day warranty, so no worries there.

Just keep in mind the California Prop 65 warning — but that's on basically everything these days.

Part numbers are L12125-001 and L09990-001.

No UPC, but you don't need it.
