RAMCHECK DDR2/DDR1 (p/n INN-8668-DDR2+1) is a popular combination package for testing and identifying industry standard 240-pin DDR2 and 184-pin DDR1 DIMM memory modules. In less than a minute, RAMCHECK will display the DIMM's size, speed and type, then perform a thorough test of the module. (Support for testing older SDRAM modules is available.)
 RAMCHECK DDR2/DDR1 is easy to use. The user will not have to read lengthy product documents or memorize complex setup procedures. Just turn the RAMCHECK base unit on, insert the memory module to be tested into the rugged test socket, then press the start button. (Of course, RAMCHECK DDR2/DDR1 allows you to define your own testing parameters if necessary.)
RAMCHECK DDR2/DDR1 is easy to upgrade by downloading the latest firmware updates directly from our website. A powerful PC interface is included, providing you with everything you need to log, print and save your test results. A convenient SPD wizard is even included for viewing and programming SPD information. Click here for complete list of the RAMCHECK DDR2/DDR1 tester's features and capabilities.
During each test, the module's size, type and structure are automatically detected. The initial Basic test takes just seconds. For more exhaustive testing, RAMCHECK DDR2/DDR1 will then perform the Extensive and AutoLoop test phases
RAMCHECK DDR2/DDR1 includes:

**The RAMCHECK DDR2 adapter can perform DDR2 tests at actual test frequencies up to 667MHz. Modules designed for 800MHz can be functionally tested on the DDR2 adapter but at a reduced frequency. The DDR2 test engine can achieve 800MHz internal diagnostic speeds. Please see the product specifications for futher details.
