System Specifications C-3
NOTE
Use only 60ns unrestricted CAS Latency 2
unbuffered 4-clock SDRAM or 60ns buffered or
unbuffered EDO DRAM. Buffered or 2-clock
SDRAM DIMMs are not supported. Note that
SDRAM DIMMs with an
nx4 DRAM base and parity
DIMMs (x72) are not supported. For example, a
DIMM that uses 16 Mbit x 4 devices should not be
used.
External Cache Memory
Your computer uses 512 KB of Pipeline Burst static RAM
(PBSRAM) integrated on the system board
Direct-mapped
Two 64K x
32 GWE (Global Write Enable) PBSRAMs
One 16K x 8 external tag SRAM
Standard tag SRAM 32K x 8.
Chipset & PCI/IDE Interface
Intel 82430TX dual PCI set (MTXC and PIIX4) features
include:
Integrated PCI bus mastering controller
430TX System Controller (MTXC North Bridge);
integrates the cache, main memory DRAM control and
provides bus control to handle transfers between the
processor, cache, main memory and PCI bus.
Microprocessor interface control.
Integrated L2 write-back cache controller supports
256K and 512K Pipeline Burst SRAM.
64 MB maximum DRAM cacheability.
Direct-mapped organization – write back only.
