2.1.3 SODIMM Installation
All 144-pin SO-DIMMs up to 64 MByte and some 128 Mbyte SO-
DIMMs that fit into X701 and X702 can be used with the BAB 740.
The firmware reads the type and size of the SO-DIMM from the SPD
(Serial Presence Detect) EEPROM installed on the memory module.
However there are some restrictions and recommendations:
·
SDRAMs should be 100 MHz or faster.
·
FPMODE or EDO RAMs should be 60 ns or faster.
·
X701 must be populated with a memory module.
·
If two memory modules are installed they should be of the
same type but may have different size. Otherwise the
firmware uses only the module installed in X701.
·
Due to performance reasons the use of SDRAM is strongly
recommended (50% advantage).
After reset the firmware tests the memory modules. If the test fails or
the firmware reports the wrong size - the module may not be suitable
for the BAB 740.
