Processor; Memory - Intel L440GX+ Product Manual

Processor

Each Pentium II or Pentium III processor is packaged in a cartridge. The cartridge includes the
processor core with an integrated 16 KB primary (L1) cache, the secondary (L2) cache, and a back
cover.
The processor implements the MMX
the 8086, 80286, Intel386
The processor's numeric coprocessor significantly increases the speed of floating point operations
and complies with ANSI/IEEE standard 754-1985.
Each processor cartridge connects to the server board through a 242 pin edge connector. The
cartridge is secured by a retention mechanism attached to the server board. Depending on
configuration, your server may have one or two processors.
The processor external interface is MP (Multi-Processor) ready and operates at 100 MHz. The
processor contains a local APIC (Advanced Programmable Interrupt Controller) section for
interrupt handling in MP and UP (Uni-Processor) environments.
The second level cache is located on the substrate of the S.E.C. cartridge. The cache includes burst
pipelined synchronous static RAM (BSRAM). The L2 cache is offered in 512 KB configurations
only, with error correcting code (ECC) that operates at half the core clock rate.

NOTE
If you install a processor that is 550 MHz or faster, and you use the server
management feature board, you must run the FRUSDR update utility.

Memory

Only 100 MHz PC/100 ECC or Non-ECC SDRAM is supported by the server board. Memory is
partitioned as four banks of SDRAM DIMMs, each providing 72 bits of noninterleaved memory
(64 bit main memory plus ECC):
•
Install from 64 MB to 2 GB of memory, using registered DIMMs.
•
Install from 32 MB to 1 GB of memory, using unbuffered DIMMs.
Memory should be added in order from slot 1 to slot 4.
/
NOTE
Do not mix registered and unbuffered memory. Non ECC memory may be
installed but ECC memory is recommended in a server environment. Mixing
Non-ECC memory and ECC memory causes all ECC features to be disabled.
The controller automatically detects, sizes, and initializes the memory array, depending on the type,
size, and speed of the installed DIMMs, and reports memory size and allocation to the server via
configuration registers.
