1.9.2 Supplementary information about DIMMs
Your PCA-6166 can accept SDRAM memory chips (with or without
parity). Also note:
•
If the PCA-6166 operates at 100 MHz, only use PC100-compliant
DIMMs. Most systems will not even boot if non-compliant modules
are used. This is due to strict timing issues involved at this speed.
•
SDRAM chips are usually thinner and have higher pin density than
EDO chips.
•
Chips with 9 chips/side support ECC; chips with 8 chips/side do not
support ECC.
•
Single-sided modules are typically 16, 32, 64 or 128 MB;
double-sided modules are usually 32, 64, 128, or 256 MB.
