 RAMCHECK DDR2 can be used "right out of the box." No lengthy manuals to wade through, no complex set up procedures to follow. Simply turn the unit on, insert your memory module into the rugged test socket, then press the start button. (Of course, RAMCHECK DDR2 allows you to define your own testing parameters if your application requires it.)
RAMCHECK DDR2 is easy to upgrade. Just download the latest firmware updates 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 a complete description of the RAMCHECK DDR2's features and capabilities.
During each test, the DDR2 module's size, type and structure are automatically detected. The initial Basic test takes just seconds. For more exhaustive testing, RAMCHECK DDR2 will then perform the Extensive and AutoLoop test phases. You may halt the test process at any time.
RAMCHECK DDR2 includes:
-
RAMCHECK* base unit (p/n INN-8668

**The new 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.
