RAMCHECK LX OWNER’S MANUAL   

5. ADVANCED TESTS 

 

 

 

 

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
