SOYO SY-6BA+ IV Personal Computer User Manual


 
Motherboard Description SY-6BA+ IV
10
two, three, or four sockets. Using the serial presence detect (SPD) data
structure, programmed into an PROM 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 256MB. 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 MB DIMM Modules
l Support unbuffered or registered 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-6BA+ IV
motherboard must comply with the PC SDRAM specifications. These
include: the PC SDRAM Specification (memory component specific), the
PC Unbuffered DIMM Specification, and the PC Serial Presence Detect
Specification.
