RAM Test Group
The
RAM Test Group
subtests check all the directly addressable RAM.
The
RAM Test Group
program has parameters for the subtests that you can set:
Test Limits
and
Options
.
Three subtests are available for RAM: the
Quick Memory Test
, the
Comprehensive Memory Test
, and the
Secondary Cache Memory Test
. The
Quick Memory Test
performs an address check to determine
whether the computer is properly setting and clearing individual bits in RAM and whether the RAM read and
write operations are affecting more than one memory address location at one time. This subtest checks all
available RAM. The
Comprehensive Memory Test
also performs an address check, as well as the
following:
Data pattern checks, to look for RAM bits that are stuck high or low, short-circuited data lines, and
some data pattern problems that are internal to the memory chips
A parity check that verifies the ability of the memory subsystem to detect errors
A refresh check, to verify that the dynamic RAM (DRAM) is being recharged properly
The
Secondary Cache Memory Test
confirms the functionality of the computer’s cache controller chip and
the cache memory.
