System Processor
The D865GLC motherboard supports a single Pentium 4 processor. The processor’s
VID pins automatically program the voltage regulator on the motherboard to the
required processor voltage. In addition, the front side bus speed is automatically
selected. The motherboard currently supports processors that run internally up to
3.06GHz and have a 512 KB second-level cache running at full CPU Speed.
The processor implements MMX ™ technology and maintains full backward
compatibility with the 8086, 80286, Intel386 ™, Intel486 ™, Pentium, Pentium Pro,
Pentium II & Pentium III processors. The processor’s numeric coprocessor
significantly increases the speed of floating-point operations and complies with
ANSI/IEEE standard 754-1985.
Microprocessor Packaging
The Pentium 4 processor comes in a micro PGA 478 package that connects to the
motherboard through a socket 478 connector. The package consists of:
• Processor card including the processor core and the second-level cache,
burst pipelined synchronous static RAM (BSRAM) and tag RAM.
•
Thermal plate.
• Back cover.
Second Level Cache
The second-level cache is located on the die of the CPU itself. The cache includes
burst pipelined synchronous static RAM (BSRAM) and tag RAM. All supported
onboard memory can be cached.
Processor Upgrades
The motherboard can be upgraded with a Pentium 4 processor that runs at higher
speeds.
System Memory
Main Memory
The motherboard has four DDR SDRAM Dual Inline Memory Module (DIMM)
sockets. Support for up to a maximum memory size of 4GB. The BIOS automatically
detects memory type, size, and speed.
The motherboard supports the following memory features:
• 2.5 V (only) 184-pin DDR SDRAM DIMMs with gold-plated contacts
•
Unbuffered, single-sided or double-sided DIMMs with the following restriction:
