RAMCHECK LX OWNER’S MANUAL 4. RAMCHECK LX OPERATION
Section 5 describes the RAMCHECK LX SETUP mode, which allows you to
perform advanced tests in which you setup your own parameters and testflow.
4.2.1 STANDBY MODE
The RAMCHECK LX begins in the STANDBY mode, where you are
prompted with the following message to insert a module and start the test:
During this mode, no devices are being tested, and RAMCHECK LX
internally tries to reduce its own power consumption.
From STANDBY mode, you may select the following actions:
F1 - starts the automatic test as described in the following sections.
F2 - allows you access to all of RAMCHECK LX’s advanced setup functions,
which are described in Section 5.
F3 - run the DEMO program.
F4
-allows you to view the Test Log, to view any modified setup of
RAMCHECK LX, or to access the SPD management program.
The Test Log is a unique feature of RAMCHECK LX. It is actually a
scrollable list of all the results obtained during the last test. The
information in the Test Log is retained until you perform a new test.
F5 -is used by our technical personnel to run the extensive diagnostic
programs.
4.2.2 BASIC TEST
The initial group of tests recognizes the memory type (DDR3, DDR2, DDR,
SDRAM, etc.) and determines the module size and DDR/SDRAM frequency
rate (or speed/cycle time for EDO/FPM). This group looks for basic wiring,
addressing, and defective bit problems. If a problem is detected, the test is
halted with the corresponding error message. If no initial problem is
detected, the test continues with every cell being written to and read from
with different basic bit patterns.
During the BASIC test, the graphic display shows animation depicting the
progress of the test, a test timer, module type, size and speed. Speed is shown
as the frequency in MHz for DDR3, DDR2, DDR1 and SDRAM devices.
