Motherboard Description
two, three, or four sockets. Using the serial presence detect (SPD) data
structure, programmed into an E²PROM on the DIMM, the BIOS can
determine the SDRAM's size and speed. Minimum DIMM memory size is
8 MB; maximum DIMM memory size is 256/512 MB. Memory size and
speed can vary between sockets.
The motherboard supports the following memory features:
l
168-pin DIMMs with gold-plated contacts
l
66/100/133 MHz SDRAM
l
Non-ECC (64-bit) and ECC (72-bit) memory
l
3.3V memory only
l
Supports 8/16/32/64/128/256/512* MB DIMM Modules
(*512MB DIMM1,2 only)
l
Support unbuffered single- or double-sided DIMMs
¿
Note
Slot 1 processors with 100 MHz front-side bus should be paired only with
100 MHz SDRAM. Processors with 66 MHz front side bus can be paired
with either 66 MHz or 100 MHz SDRAM.
1-8.2 SDRAM
SDRAM improves memory performance through memory access that is
synchronous with the front-side bus clock. Burst transfer rates at x-1-1-1
timing can be achieved using SDRAM, while asynchronous memory
subsystem are typically limited at x-2-2-2 transfer rates.
¿
Note
All memory components and DIMMs used with the SY-6VBA133–B
motherboard must comply with the PC SDRAM specifications. These
include: the PC SDRAM Specification (memory component specific), the
PC Unbuffered DIMD Specification, and the PC Serial Presence Detect
Specification.
