DRAM Test
The purpose of this test is to check the validity of DRAM, both standard and
optional. The test writes patterns of data to SDRAM to verify that each bit in
memory can be set and read correctly.
To run the SDRAM Memory Test:
1. Select DRAM Test from the menu. The power indicator blinks
indicating the test is in progress.
xxxMB represents the amount of installed DRAM memory in MB.
P:###### represents the number of times the memory test has
passed and finished successfully. Initially 000000 displays with the
maximum pass count being 999,999.
F:##### represents the number of times the memory test has failed
and finished with errors. Initially 00000 displays with the maximum fail
count being 99,999.
2. Once the maximum pass count or fail count is reached, the test stops,
the power indicator is turned on solid, and the final results display. If the
test fails, the message DRAM Error displays for approximately three
seconds and the failure count increases by 1.
Turn the power off if you want to stop the test before it completes.
