Fast, reliable memory testing for DDR3 DIMMs

The RAMCHECK DDR3 Adapter (p/n INN-8668-16) supports testing of 240-pin PC3-6400, PC3-8500, PC3-10600, and PC3-12800 DDR3 memory, including unbuffered (UDIMM) and registered modules (RDIMM), both ECC and non-ECC, that comply with JEDEC standards, and LRDIMM (RAMCHECK LX only).

The DDR3 adapter plugs into the existing RAMCHECK or RAMCHECK LX base tester. This makes the DDR3 adapter by far the most cost-effective solution for testing modern high-speed DDR3 modules. In fact, its features are what you would expect to find in test equipment that costs $20,000 or more.

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/RAMCHECK LX tester on, place a module into the test socket, then press the start button.

DDR3 Advanced Technology

We have incorporated state-of-the-art technology in the design of the new RAMCHECK DDR3 Adapter.

DDR3 adapter board

1. Main controller featuring our improved 1066MHz test engine.
2. High efficiency switching power regulator to generate the DDR3 STTL-15 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. 400-1333MHz DDR3 clock generator.
6. Digitally-controlled high resolution VDD high efficiency switching power regulator.

The RAMCHECK DDR3 adapter includes many new features which are relevant to the differences between DDR3 technology and the older DDR2 and DDR technology.

As with all of our RAMCHECK/RAMCHECK LX 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 DDR3 adapter is very simple to operate, with little training or setup required.

Introducing the DDR3 Adapter

DDR3 RAMCHECK LX DDR3/DDR2 includes a large, vivid, high-contrast display measuring 2.7" x 1.43" (69mm x 36.5mm). Easily viewable at an angle, up to 3-4 feet away. Seen here is the startup screen once the RAMCHECK LX DDR3/DDR2 is turned on.
 Basic Test
                              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 1066MHz with an automatic setting of CAS Latency to the default value of CL=6 for this frequency.
                              Basic Test OK Successful test phases conclude with a clear 'Pass' message and with distinguishing sound tones. Important parameters are shown in this screen, followed by a detailed test results summary screen.
  Test Results
RAMCHECK test log summary Test results summary screens provide a wealth of information after each test phase. All summary screens are also added to the Test Log.
RAMCHECK LX Test Log Test Log collects and retains all intermediary test results while the memory devices undergo all of the test phases. The Test Log remains until a new test is initiated. The Test Log may be uploaded to a PC for printing via the USB interface. You can also save the file.
 Extensive Test
RAMCHECK LX extensive test The EXTENSIVE Test performs various tests to establish memory quality.
voltage cycling VOLTAGE CYCLING performs tests under allowable voltage deviations from the recommended VDD setting.
                              Test MODE Test identifies various operational parameters of the device, including different bursts lengths and CAS latency settings.
Voltage Bounce VOLTAGE BOUNCE tests data retention during voltage variation between read and write.
March Up/March Down MARCH UP/DOWN reveals adjacent cell interference problems.
Chip Heat Mode CHIP HEAT MODE tests at elevated operating temperatures.
Autoloop AUTO LOOP tests memory with endless pattern changes. Great for burn-in testing.
 Change-on-the-fly and Setup
DDR3 coft 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.
DDR3 cotf Here we demonstrate how the module's frequency is overriden to 866MHz from a previous test at 800MHz.
DDR3 cotf CAS Latency can be set at 5,6,7,8,9,10,11, and 12. Please note that not all DDR3 modules support all CL values.
DDR3 setup Various Rtt_NOM and Rtt_WR (dynamic Rtt) can be set up by the user.
DDR3 setup The DDR3 VDD Voltage setup allows the user to change on-the-fly the test voltage in the range 1.35V-1.8V. When set to AUTO, RAMCHECK automatically tests the module at 1.5V/1.6V. In this example, the user is selecting a VDD of 1.57 Volt.
RAMCHECK LX Test Log The RAMCHECK LX provide advanced setup features. Certain timing parameters may be selected graphically as shown here.
 Wiring Errors Detection
Wiring Errors The DDR3 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.
Wiring Errors Address lines errors in the DDR3 modules are reported explicitly as shown in this example. Here address line A2 (pin 61) is shorted to ground.
Wiring Errors The DDR3 module uses ODT control lines to activate the internal Rtt termination resistors. In this test error example, line ODT0 (pin 195) is shorted to ground.
   SPD Editor
RAMCHECK LX Test Log The device's SPD can be conveniently viewed, edited and programmed on the RAMCHECK LX. You can also use our advanced SPD features in the PC RAMCHECK LX communications program.

The new DDR3 incorporate numerous enhancement over our previous DDR2 technology, some of which are currently implement in the diagnostic tests and will be fully enabled in upcoming firmware versions. Please make sure that your base tester (RAMCHECK LX or RAMCHECK) always has the latest firmware installed. Please note that the following technical specifications are subject to change while we introduce this new DDR3 technology.
