SIS-8601-LVA
2.2 Main Memory Installation: DIMM1
The SIS-8601-LVA ISA Industrial CPU Card supports one dual inline memory module
(DIMM 168-pin) sockets for a maximum memory of 512MB on PC100/133 . Using the serial
presence detect (SPD) data structure, programmed into an E
2
PROM on the DIMM, the BIOS
can determine the size of SDRAM and speed. Minimum memory size is 64MB; maximum
memory size is 512MB.
The CPU card supports the following memory features:
• 168-pin DIMM with gold-plated contacts
• 100 or 133 MHz SDRAM
• Non-ECC (64-bit) .
• 3.3V memory only
• Un-buffer single or double-sided DIMM in the following sizes:
SDRAM
SYNCHRONOUS DRAM (SDRAM) improves memory performance through memory
access that is synchronous with the memory clock. Burst transfer rates at x-1-1-1 timing can be
achieved using SDRAM, while asynchronous memory subsystems are typically limited at x-2-
2-2 transfer rates.
The CPU card supports single or double-sided DIMM in the following sizes:
DIMM size Non-ECC configuration
64MB 8Mbit x 64
128MB 16Mbit x 64
256MB 32Mbit x 64
512MB 64Mbit x 64
Note: All memory components and DIMM used with the SIS-8601-LVA ISA CPU card must
comply with the PC SDRAM Specification. These include: the PC SDRAM Specification
(memory component specific), the PC Un-buffered DIMM Specification, and the PC Serial
Presence Detect Specification.
