1.9.2 Supplementary information about DIMMs

Your PCA-6178 can accept SDRAM memory chips (with or without

parity). Also note:

• If the PCA-6178 operates at 100 MHz, only use PC/100-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 or 64 MB; double-sided

modules are usually 32, 64, 128, or 256 MB.
