Pentium Ii Processor; System Memory - NEC EXPRESS5800 LC1400 series User Manual

Pentium II Processor

The system board includes a Pentium II processor that includes the processor core with
an integrated 16 KB primary (L1) cache and a secondary (L2) cache. The processor
implements the MMX
significantly increases the speed of floating-point operations.
The processor external interface operates at a maximum of 100 MHz. The second-level
cache is located on the substrate of the SEC cartridge. The cache includes burst
pipelined synchronous static RAM (BSRAM). The L2 cache is offered with error
correcting code (ECC) that operates at half the core clock rate.

System Memory

The system board contains three 168-pin DIMM sockets. Memory is partitioned as
three banks of SDRAM DIMMs, each providing 72 bits of noninterleaved memory (64-
bit main memory plus ECC). Your system may include from 32 MB to 768 MB of
memory, using up to three DIMMs.
System memory begins at address 0 and is continuous (flat addressing) up to the
maximum amount of DRAM installed (exception: system memory is noncontiguous in
the ranges defined as memory holes using configuration registers). The system supports
both base (conventional) and extended memory.
