Introducing the DDR Pro adapter, the latest advanced test adapter for RAMCHECK. This new high-speed DDR test adapter features advanced circuitry and a powerful high-frequency test engine, allowing you to fully test and identify PC433/466 DDR modules, with planned upgrades to 533MHz.
The new 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.
DDR Pro Advanced Technology
- State-of-the-art XILINX Virtex II Pro controller featuring our improved high-speed DDR test engine
- Vtt generator for true STTL-2 testing.
- Advanced analog section for measuring module's current, voltages and the board's temperature.
- Digitally-controlled high resolution VDD regulator.
- 200-533MHz DDR clock generator.
The RAMCHECK DDR Pro adapter includes many new features not available in our older DDR test adapter, including the ability to control voltage settings (2.2-3 volt) and CAS Latency selection.
New RAMCHECK DDR Pro Features
 |
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. |
 |
The 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 phase. |
 |
In this example, the CAS LATENCY was fixed to CL=2.5 throughout the tests. |
 |
The 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. |
 |
CAS 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. DIMM DDR converter and the 66-pin TSOP DDR Chip Tester.
DDR Pro Feature
| Supports Burst Length of 2, 4, and 8. |
| Supports CAS LATENCY of 2, 2.5, and 3. Default test allow automatic selection of CL=2 and CL=2.5 for different test phases. The user can select specific CL values using SETUP or the CHANGE-ON-THE-FLY feature |
| DDR Data rates : 466MHz, 433MHz, 400MHz, 360MHz, 333MHz, 266MHz, 233MHz and 200MHz. (support for 533MHz and 500MHz will be added soon in the form of an optional hardware upgrade). |
| True 2.5V testing with a wide support range of 2.2V to 3.0V at +/-50mV increments. While this range is sufficient to cover all popular DDR module, it can be extended using a special setup code. |
| Improved current and temperature measurement circuitry. |
| Controlled Vtt for true STTL-2 compatibility. |
| Parallel testing capability of 64/72-bits |
| Rugged, test-quality ZIF socket for convenient module handling. |
| Automatic detection and support for Registered/Unbuffered modules. |
| Automatic DQS8..0/DM8..0 or DQS17..0 support. |
| Four -S control lines for up to 4-rank devices. |
| Fourteen A13..0 address lines and three BA2..0 bank select address lines to support 4GB modules. |
| Complete SPD programming support. |
| Supports optional converter for 200-pin S.O. DIMM modules (p/n INN-8668-1) and future converters. |
If you need a test solution for nonstandard or proprietary memory, the DDR Pro's advanced technology also makes it much easier to build custom adapters and converters. Please contact our Technical Support Department for additional information.
