  RAMCHECK LX OWNER’S MANUAL 

4.  RAMCHECK LX OPERATION   

 

 

This section outlines the operation of RAMCHECK LX.  It instructs you on 

how to handle the test sockets, and describes the RAMCHECK LX tests in 

some detail. Please note that actual screen displays may vary as 

RAMCHECK LX’s firmware is modified, or if you swap adapters. 

 

     

CAUTION

 

 

1. Do not insert or 

remove a module 

when the Module 

Power  red  LED is 

on! (Press ESC to 

turn it off prior to 

insertion/removal.) 

 

2. Never use excessive 

force to insert a 

DIMM module.  If a 

module is not 

sliding in smoothly 

-  please review the 

manual addendum 

for the adapter: 

 

www.memorytesters.

com/tec_man.htm

 

 

3. Keep the test socket 

empty when  the 

RAMCHECK  LX

  is 

turned on, to allow 

the adapter to be 

fully configured be-

fore  you insert the 

module. 

4.1  INSERTION AND REMOVAL OF MODULES 

   

INSERTION:

  

 

Make sure the Module Power 

red

 LED on the front of the RAMCHECK LX 

is off (if not - press ESC). RAMCHECK LX adapters use vertically mounted 

high-quality test sockets  with two ejectors that need to be opened prior to 

insertion.  Carefully insert the DIMM into the socket, pushing it evenly along 

its top.  When the DIMM is properly inserted, the ejectors will snap onto the 

semi-circular notches on each side of the module. 

 

REMOVAL: 

 

Make sure that the Module Power 

red

 LED is off (if not - press ESC).  In 

certain modules, the 

red

 LED may still be glowing slightly, even when the 

tester is in Standby Mode; if this occurs, it is still safe to remove the module 

from the socket (only in Standby Mode), as the module is allowing only a 

minor amount of leakage current to flow.  This however, should not be 

interpreted as an indication of a defective device.   

 

Place one finger on top of the DIMM module to 

prevent the module from 

popping upward

 and simultaneously pull both ejectors sideways. 

 

NOTE:  The Yamaichi sockets (used in DDR3/2/1 adapters) are rated for 

10,000 to 20,000 insertion/removal cycles.  We cannot guarantee that the 

actual number of cycles will meet the above rating since the sockets are 

subject to wear and tear and potential rough handling. Using it carefully 

will provide you with a long period of use.   

 

Replacement test socket are available for purchase. (Please note that some 

test heads and inexpensive converters do not use rugged sockets. These units 

are inexpensively replaced when worn out.)   

 

 

4.2  TEST PHASES 

 

The main tests performed by the RAMCHECK LX, including the BASIC test, 

the EXTENSIVE test and the AUTO-LOOP, are MULTI-BYTE tests where 

all the data bus bits are checked simultaneously.  

 

RAMCHECK LX starts with the BASIC test, which lasts between 3 and 60 

seconds, depending on module size  and type.  The EXTENSIVE test 

automatically follows the BASIC test and it lasts several minutes.  It includes 

different voltage and temperature related test procedures, as well as mode 

analysis.  The AUTO-LOOP test  proceeds in an endless loop of varying 

pattern (and algorithm) tests.
