RAMCHECK DDR2 240-PIN ADAPTER Introducing the new RAMCHECK DDR2 Adapter (p/n INN-8668-15), the latest advanced memory test adapter for RAMCHECK LX and RAMCHECK. The RAMCHECK DDR2 adapter supports testing of 240-pin PC2-6400, PC2-5300/PC2-5400, PC2-4300 and PC2-3200 DDR2 memory, including unbuffered (UDIMM) and registered modules (RDIMM), both ECC and non-ECC, that comply with JEDEC standards. The adapter can achieve a maximum frequency of 866MHz. (Please see this page for information about DDR2 fully-buffered FB-DIMM devices.) The new DDR2 adapter plugs into the existing RAMCHECK or RAMCHECK LX base tester. This makes the DDR2 adapter by far the most cost-effective solution for testing modern high-speed DDR2 modules. In fact, its features are what you would expect to find in test equipment that costs $20,000 or more. Click here to download the one page spec sheet. Don't let the adapter's small size fool you! High speed operations require short connections, while the adapter is loaded with state-of-the-art electronic components. No special setup is required. As with all of our products, the adapter is extraordinarily simple to use. Insert the adapter, turn the RAMCHECK tester on, place a module into the test socket, then press the start button. The DDR2 adapter will not work with the older SIMCHECK II tester, although these units can be factory-converted to the RAMCHECK. We have incorporated state-of-the-art technology in the design of the new RAMCHECK DDR2 Adapter. The following pictures provide you with a look "under the hood."        DDR2 Advanced Technology  1. State-of-the-art controller featuring our improved 866MHz second generation DDR2 test engine. 2. State-of-the-art high efficiency switching power regulator to generate the DDR2 STTL-18 interface power source. 3. Advanced analog section for measuring the module's current, voltages and the board's temperature. 4. Digitally-controlled Vtt regulator. 5. 333-1100MHz DDR2 clock generator. 6. Digitally-controlled high resolution VDD high efficiency switching power regulator. Provides twice the current capabilities of the previous version of the DDR2 adapter. The RAMCHECK DDR2 adapter includes many new features which are relevant to the differences between DDR2 technology and the older DDR technology. It also includes many of the new advanced features first introduced with our DDR Pro. Please see the screen shots below (with the RAMCHECK LX base tester display). Introducing the RAMCHECK DDR2 RAMCHECK automatically identifies the presence of the new DDR2 adapter. RAMCHECK prompts the user to insert a 240-pin DDR2 module and start the test with F1.    BASIC TEST 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 800MHz with an automatic setting of CAS Latency to the default value of CL=5 for this frequency. In this Basic Test screen we test a 64Mx64 ECC module at 667MHz with the default CAS Latency of 4. This module is unbuffered. In this Basic Test screen we test a 128Mx64 (1GB) module at 533MHz with a reduced CAS Latency of 3. Some 533MHz modules which are normally designed for CL=4 may still pass tests conducted at the more demanding CL=3. The DDR2 adapter supports all popular Unbuffered, Registered modules. In this Basic Test screen we test a Unbuffered 32M64 (256MB) module at 533Hz with the default CAS Latency of 4. In this Basic Test screen we test a Registered 64Mx72 (512MB) module at 400MHz with the default CAS Latency of 3. In addition to the industry standard frequencies of 400MHz, 533MHz 667MHz and 800MHz, we also offer testing at the additional frequencies of 866MHz, 600MHz and 466MHz. These frequencies can be used to gauge if a given module can run at slightly higher frequencies than it is marked for. This screen appears upon a successful completion of the Basic Test. It is followed with several detailed screens with detailed information about the module's size and structure. This sample structure information screen indicates that the module was tested at the default 1.90V. CAS Latency was the default 3/4 setting, in which the program automatically select CL=5 for frequencies of 533MHz and higher. This sample structure information screen states that the currently tested PC2-6400 module has its SPD set for 800MHz at CL 5 and 667MHz at CL4.    PARAMETERS, CHANGE-ON-THE-FLY AND SETUP Expanded CHANGE-ON-THE-FLY can be used to set up the Frequency, the Voltage, the CAS LATENCY and the Refresh rate only for the current test. Following the current test, it returns to the current setup parameters. Here we demonstrate how the module's frequency is overriden to 866MHz from a previous test at 800MHz. CAS Latency can be set at 2,3,4,5,6. Please note that not all DDR2 modules support CL of 2 and 6. By default, the test program selects CL=3 for 400MHz and 466MHz, CL=4 for 533MHz and 667Mhz, and CL=5 for 800MHz. At 667MHz, the test program dynamically tries to test the module at CL=5 if CL=4 fails. This example shows testing at 800MHz with a forced CAS Latency of CL=5. This test ended successfully. The new DDR2 VDD Voltage setup allows the user to change on-the-fly the test voltage in the range 1.5V-2.2V. When set to AUTO, RAMCHECK automatically tests the module at 1.8V/1.9V. In this example, the user is selecting a VDD of 1.94 Volt.    WIRING ERRORS DETECTION Unlike older DDR, the DDR2 devices utilize the differential DQS technique which assigns a pair of two control lines per each DQS. In this test error example, DQS4 line (pin 84) was stuck at 1. The DDR2 module uses new ODT control line. In this test error example, line ODT1 (pin 77) is shorted to ground.    EXTENSIVE TEST During Voltage Cycling, the module is tested at various voltages, which are automatically selected based on the current frequency. Higher frequencies require higher voltages. The March UP/DOWN test attempts to capture pattern sensitivity and addressing errors. The Extensive Test ends with the Final Test. The module is heated up by this point so that the test indicates the ability of the module to work at elevated temperature.     AUTO-LOOP TEST The AUTO-LOOP test is great for extended burn-in. This test continues forever when there are no failures in the device. It is terminated by the user. It similarly follows our standard AUTO-LOOP for SDRAM and DDR1 devices. As with all of our RAMCHECK testers, each module's size, structure, and type are automatically detected, without the need for user's setup. The test flow follows our standard Basic Test, Extensive Test, and Auto-Loop process. The RAMCHECK DDR2 adapter is very simple to operate, with little training or setup required. DDR2 Test Features Supports Burst Length of 4, and 8. Supports CAS LATENCY (CL) in the range of 2,3,4,5,6. Trcd is supported in the range of 3,4,5, and 6. Additive Latency is supported in the rane of 0,1,2,3,4, and 5. The test allows automatic selection of CL and Trcd for different test phases. The user can select specific CL values using SETUP or the CHANGE-ON-THE-FLY feature. DDR2 Data rates : 866MHz, 833MHz, 800MHz, 733MHz, 667MHz, 533MHz, 466MHz and 400MHz.
