HP Z4 G4 Workstation Motherboard

This HP Z4 G4 workstation motherboard uses the LGA2066 socket for Intel Xeon processors. It provides eight memory slots for high-capacity configurations. The board carries part numbers L09990-001, L12125-001 and L12125-601. It is supplied in new condition.

Suited for Xeon LGA2066 upgrades

This board suits technicians repairing or upgrading an existing HP Z4 G4 chassis that requires the LGA2066 socket. It is not for builders starting a new system with a different processor platform or socket type. Buyers needing a retail motherboard with full overclocking controls should look elsewhere. The proprietary form factor limits use to compatible HP workstation enclosures.

LGA2066 socket compatibility

The single specification that decides fitment is the LGA2066 CPU socket. Only Intel Xeon processors designed for this socket will install and operate. Verify the exact processor model against the workstation service guide before purchase. An incompatible CPU will not seat or function on this board.
