Motherboard and CPU Compatibility
In stock configuration, the ApogeeÂ? LP is compatible with:
- Intel® desktop and server processors using socket LGA775, 1156 & 1366 - The Intel-universal hold-down plate is installed by default. Motherboard back plates for desktop boards class boards in 1156 and 1366 socket are included. Socket 775 back-plate is sent free of charge upon request. In server class boards, the waterblock bolts directly onto the existing motherboard back-plate.
- Optional Part # Apogee-GTZ-AM2-HD, provides compatibility with AMD® Socket AM2, and AM3 and is fully compliant with the component keep-out specification.

AMD® desktop and server processors using socket AM2 and AM3 - Installation of the hold-plate is required.
Optional Part # Apogee-GTZ-1U-S-HD, is a multi-platform hold-down plate and provides compatibility with the following legacy sockets:
Intel® XeonÂ? socket 771, and legacy 603, 604
AMD® socket F, and legacy 754, 939, 940
Due to the hybrid nature of this hold-down solution, users are advised to check for possible clearance issues with their particular motherboards by using the schematic below.
