The RAMCHECK
LX screen has eight
lines of text but only
four lines may be
shown to save space.
1G to 2G. Press F1 ENTER to set the size you selected.
Upon entering the size, you are then prompted to enter the bit configuration
of your module.

and

can be used to either increase or decrease the value
on the display and

and

can be used to move the cursor position either
left or right. Press F1 ENTER to set the bit configuration you selected.
Afterwards, you are prompted to select whether your setup will fail modules
not meeting this size, or whether the DUT should be partially tested.
Pressing

will highlight TEST DUT AT SETUP SIZE, forcing smaller
modules to fail and larger modules to only be tested at the size entered.
5.3.2 TIMING
This selection will display the Setup Timing menu. You may choose to setup
the speed or frequency of the module, or change either the RAS to CAS delay
time (Trcd) or the Row address Hold Time (Trah). If a previous timing
parameter was entered and you wish to reset it to the default timing setup,
simply select F4 AUTO. Selecting F5 for Next Menu allows you to enter the
Advanced Code Setup Menu. Please use Code setup only if instructed by our
Tech Support department.
SPEED SETUP:

DDR3, DDR2, DDR1
and SDRAM devices
use frequency setup.
Legacy EDO/FPM
devices use access
time setup.
5.3.2.1 SPEED SETUP
Selecting this function will allow you to change the current setup for the
access time from RAS or the DDR3/DDR2/DDR1/SDRAM frequencies.
Selecting F1 allows you to determine the test frequencies at which
RAMCHECK LX will access DDR3/DDR2/DDR1/SDRAM memory.
Use the

and

keys to scroll through the available frequencies.
RAMCHECK LX will now run modules strictly at the 667MHz level. The
range of frequencies automatically changes to fit the current RAMCHECK
LX configuration. DDR2 frequencies are higher than DDR1 frequencies
which in turn are higher than the older SDRAM frequencies.
Pressing F2 selects the EDO/FPM access time from RAS. The

and

keys are used to position the cursor, while the

and

keys allow you to
either increase or decrease the value at the current cursor position. To return
to AUTO SPEED, simply press F5 until the cursor reaches its last position on
the right. To enter your selected speed setting, press F1 .
After presetting the speed, RAMCHECK LX allows you to select whether the
value entered will be used for the default setup speed, or if it is to be used as a
