Memory Checkout
Depending on the model, the memory size that is available
for customer use appears differently. This is not a
hardware problem. See the following table for the
available memory size of each card.
Note: For Models 370C, 755C and 755Cs, one of two
types of memory cards can be used, IC DRAM card or
DIMM card. If DIMM cards are installed, replace IC DRAM
with DIMM in the following.
Memory errors might stop system operations, show error
messages on the screen, or hang the system. The
computer detects memory parity errors but does not
correct them.
Use the following procedure to isolate memory problems.
Notes on Memory Errors
For Models 355x, 360x, and 370C, ignore any
references to parity errors.
DIMM Adapter and DIMM card are not supported
for 355x and 360x. Remove them (if installed).
1. Installing a non-parity memory card causes memory
errors. Before you go to the next procedure, check
whether or not the memory card use parity or
non-parity. If the non-parity memory card is installed,
disable the parity check on Easy-Setup configuration
screen.
2. Make sure that the memory card is fully installed into
the connector. Loose connection can cause an error.
