SDVIA uses Dual Inline Memory Modules (DIMMs). Four DIMM slots are available
for 3.3Volt (power level) unbuffered Synchronous Dynam ic Random Access
Memory (SDRAM) SDRAM with 32, 64, 128 ,256 or 512 MB com binations to form
a m em ory s ize betw een 32 MB and 1 .5GB. SD VIA als o s u pports VCM DR AM.
IMPORTANT
!"
Use only Intel PC100-or PC133 com pliant Unbuffered DIMMs and VCM
D R AM. If th e FSB is at 100 or 133 MH z a nd non-com plian t modules are used,
system will not boot because of the strict timing issues involved under this
speed.
!"
Unbuffered DIMMs and VCM DRAM should not be mixed and used together.
Install mem ory in any combination as follows:
