Motherboard Description SY-K7VTA
10
1-7 MEMORY
1-7.1 Main Memory
The motherboard has three DIMM sockets. SDRAM can be installed in
one, two, or three 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:
DRAM interface synchronous with host CPU (66/100/133MHz) or
AGP (66MHz) for more flexible configuration
DRAM interface may be faster than CPU by 33 MHz to allow use
of PC133 memory modules
DRAM interface may be slower than CPU by 33 MHz to allow use
of older memory modules with newer CPUs
Concurrent CPU, AGP, and PCI access
Supports SDRAM and VCM SDRAM memory types
Different DRAM types may be used in mixed combinations
Different DRAM timing for each bank
Dynamic Clock Enable (CKE) control for SDRAM power
reduction in high speed system.
Mixed 1M/2M/4M/8M/16M/32MxN DRAMs
The K7VTA supports 3 DIMMs or 6 banks at 133MHz for 1.5GB
(max memory)
Flexible row and column addresses
64-bit data width and 3.3V DRAM interface
Programmable I/O drive capability for MA, command, and MD
signals
Supports PC100 and PC133 SDRAM
Two-bank interleaving for 16Mbit SDRAM support
Two-bank and four bank interleaving for 64Mbit SDRAM support
Independent SDRAM control for each bank
