MEMORY
1-8.1 Main Memory
The motherboard has two DIMM sockets. SDRAM can be installed in one,
two, or 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 most flexible configuration
DRAM interface may be faster than CPU by 33 MHz to allow use
of PC100 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 K7VLM-B supports 2 DIMMs or 6 banks at 133MHz for 1GB
max memory)
Flexible row and column addresses
64-bit data width only
3.3V DRAM interface with 5V-tolerant inputs
Programmable I/O drive capability for MA, command, and MD
signals
Dual copies of MA signals for improved drive
Optional bank-by-bank ECC (single-bit error correction and multi-
bit error detection) or EC(error checking only) for DRAM integrity
