The DDR Pro adapter (part number
INN-8668-9) features advanced circuitry and a powerful high-frequency test
engine. The DDR Pro allow you to fully test and identify PC433/466 DDR modules,
with planned upgrades to higher speed devices.
The DDR Pro adapter plugs into the existing RAMCHECK base tester. This makes
DDR Pro by far the most cost-effective solution for testing high-speed DDR
modules. In fact, DDR Pro's features are what you would expect to find in test
equipment that costs $20,000 or more. It works with both the

The RAMCHECK DDR Pro adapter includes many
features not available in our older DDR test adapter, including the ability to
control voltage settings (2.2-3 volt) and CAS Latency selection.
|RAMCHECK DDR Pro
||Basic Test screen shows the size, the speed, the voltage, the test
pattern, the module's bank and the CAS Latency. This example shows testing at
466MHz. (533MHz testing will be available within a few months.)
||Users can set up the frequency, the test voltage and the CAS
LATENCY either through setup or CHANGE-ON-THE-FLY. This example shows a module
that was setup to run at 500MHz and at 2.90V.
||Setup Parameters menu allows the user to setup the Frequency, the
Voltage, the CAS LATENCY, the Refresh rate and much more. These setup values
remain in effect until changed by the user. Each parameter has a default value
that can be reset by the user.
||Expanded CHANGE-ON-THE-FLY can be used to setup the Frequency, the
Voltage, the CAS LATENCY and the Refresh rate only for the current test.
Following test, it returns to the current setup parameters.
DDR PRO allows you to set up the CAS LATENCY. This screen shows our default
setup which allows the test program to selected CL=2 or CL=2.5 during each test
this example, the CAS LATENCY was fixed to CL=2.5 throughout the tests.
new DDR PRO VDD Voltage setup allows the user to change on-the-fly the test
voltage in the range 2.2V-3.0V. When set to AUTO, RAMCHECK automatically tests
the module at 2.5V/2.7V.
||Unlike the CHANGE-ON-THE-FLY above where the new voltage setup is
effective for one test, you can use the Setup Parameters to change the test
voltage parameters for all tests.
||RAMCHECK Basic Test provides several screens for test result. The
third structure screen shown here includes some of the new features of the DDR
PRO, including the CAS LATENCY and the voltage setup.
||Here is another example where the CAS LATENCY was set at CL3 ONLY
and the voltage left at automatic mode (2.5V for modules running up to 333MHz,
2.7V for higher speed modules).
||RAMCHECK's built in test log shows the actual voltage of the test.
LATENCY override is shown in the Test Log. In this example, the module is
tested at CL=3 only. In the automatic (default) mode, the CAS LATENCY is
changed between CL=2 and CL=2.5
As with all of our RAMCHECK testers, each module's
size, structure, and type are automatically detected, without the need for
user's setup. Test flow of the DDR modules follows our standard Basic Test,
Extensive Test, and Auto-Loop process. DDR Pro is very simple to operate, with
little training or setup required.
The DDR Pro also supports the RAMCHECK 200-pin S.O.

If you need a test solution for non-standard or
proprietary memory, the DDR Pro's advanced technology also makes it much easier
to build customized adapters and converters. Current users of the older
RAMCHECK DDR adapter (p/n INN-8668-6) may also convert their existing adapter
to the RAMCHECK DDR Pro level at a substantial savings.
