Processor Subsystem
The Intel
®
Server Board X38ML supports one Intel
®
Xeon
®
or workstation processor utilizing
Flip-Chip Land Grid Array (LGA) package technology, with an LGA775 socket. The supported
processors are based on the Intel
®
Core™ micro-architecture and built on 65 nm and 45 nm
process technologies. They maintain compatibility with 32-bit software written for the IA-32
instruction set, while supporting 64-bit native mode operation when coupled with supported 64-
bit operating systems and applications. Previous generations of Intel
®
processors are not
supported.

Intel
®
X38 Chipset
The Intel
®
Server Board X38ML is designed around the Intel
®
X38 chipset. The chipset consists
of two components that work together to provide the interface between all major subsystems
found on the server board, including the processor, memory, and I/O subsystems. These
components are:
Memory Controller Hub (Intel
®
X38 MCH)
I/O Controller Hub (Intel
®
ICH9-R)
