2-3 SYSTEM MEMORY INSTALLATION
The 6240V provides four 168-pin DIMM sockets for system memory expansion
from 8MB to 1.0GB Unbuffered SDRAM for VIA Apollo Pro+ chipset or 1.5GB
Unbuffered SDRAM for VIA Apollo 133 chipset. These four DIMMs are arranged to
four banks, please refer to page A.

u
For 66MHz host bus CPUs use 12ns or faster DIMM module;
u
For 100MHz host bus CPUs use 10ns or faster and PC-100 compliant
modules .
u
Please insert 512MB memory module to DIMM 1 and DIMM2.
@
SPD (Serial Presence Detect)
This EPROM contains speed and design information of the memory module. The
mainboard may get optimal performance via accessing the data of SPD.
@
ECC (Error Check and Correction)
This mainboard can support the ECC function while utilizing parity modules. To enable
this function, users must set “DRAM Data Integrity Mode” to “ECC” through “Chipset
Features Setup” from the BIOS setup screen. All in all, ECC’s function is to detect and
correct the errors of transfer data.
