INSTALLING MEMORY
6.2.1 System Memory (SDRAM)
The PCI-934 board supports FPM and EDO memory types.
Memory specifications are as follows: vertical SIMMs (Single In-line Memory Module),
single-sided or double-sided, 5V, 32/36-bit, 70ns/60ns, Error Checking and Correction
(ECC) or parity with 36-bit SIMMs.
The memory sockets consist of four 72-pin vertical SIMM sockets divided into two banks
labeled: Bank 0 (U29 and U32) and Bank 1 (U34 and U39).
B ank 0
B ank 1
At least 8 MB of system memory (2 SIMMs of 4 MB) must be installed for proper operation.
Memory can be configured from 8 MB to 512 MB using the following modules:
1M x 32-bit / 36-bit = 4MB module
2M x 32-bit / 36-bit = 8MB module
4M x 32-bit / 36-bit = 16MB module
NOTE
The memory banks can be populated separately or jointly. Each bank
must be installed with the same SIMM capacity, however the SIMM
capacity used in one bank may be of a different capacity from the
other bank.

8M x 32-bit / 36-bit = 32MB module
16M x 32-bit / 36-bit = 64MB module
32M x 32-bit / 36-bit = 128MB module
