Extended Memory Test
Selects a complete RAM test, including READ-
WRITE test, test for proper RAM refresh, and a check for
addressing errors. Bad chips are indicated by socket
and row location (i.e. U4,D). In addition, all memory
errors are reported by memory location. Bad chips
generally require replacement. Remove the problem
chip using a small screwdriver or other appropriate tool to
pry the chip up, little by little, each end a little at a time.
Refer to INSTALLING RAM CHIPS IN THE RAMPAK
4GS on page 5 for further instructions. The EXTENDED
MEMORY TEST is recommended only when you
suspect there is a memory problem, but the QUICK
MEMORY TEST doesn’t reveal a problem. The
EXTENDED MEMORY TEST takes substantially more
time to execute than the QUICK MEMORY TEST. The
length of the test is dependent on the amount of RAM
installed on the RamPak. Roughly 20 minutes is
required to test a full 4 megabytes.
Execute Test Now
Performs test immediately, without exiting the
program or installing any other settings. This is valuable
when seeking a specific problem. For running a test as
part of your routine memory set-up, simply select the
desired test before using the DONE--INSTALL
CHANGES selection under the FILE menu.
Selecting Execute Test Now opens the Memory Test
dialog box. You will have the option of running the
requested test one time, a user specified number of
times, or loop forever. The user can exit Diagnostics at
any time by pressing the “ESC’ key.
The Settings Menu
Under this menu, you are able to configure the
caching and statistical parameters of the RamPak, as well
as allocate RAM among the various caching functions.
But before setting up caches and using statistics, it is
important to understand what they offer:
The Concept of Caching
Often, users confuse caching with RAM disks,
