RAMCHECK DDR2 Adapter Key Features
  • Tests and identifies 240-pin PC2-6400/5300/4300/3200 DDR2 modules at true clock speed.
  • Supports Registered (RDIMM), Unbuffered (UDIMM) and ECC DDR2 modules up to 8GB+.
  • Reliable and affordable, very simple to operate - size, speed and structure are automatically detected by the tester. No need for user setup.
  • Rugged test socket for heavy use.
  • Very fast. Test a 1GB DDR2 DIMM in less than one minute (Basic test).
  • Supports SPD programming.
  • Automatic and user controlled test parameters of Trcd, CAS Latency (CL), Additive Latency (AL), Write Recovery (WR), OCD and more.
  • Upgrade with free firmware upgrades available online.
  • Includes powerful SPD Wizard for programming, editing saving SPD files.
DDR2 Specifications

Basic Test
  • Identifies module type, size, configuration, voltage and frequency
  • Checks open/short, addressing and identifies defective bits

Extensive Test
  • Voltage Cycling
  • Voltage Bounce
  • March Up/Down
  • Special DDR2 Tests
  • Temperature Stress Test

Auto-Loop Test
  • Module is endlessly tested with different pattern bits
  • Detects pattern sensitivity problems
  • Excellent for burn-in procedure

Test Frequencies
  • Test DDR2 modules at 866MHz, 800MHz, 667MHz, 600MHz, 533MHz, 466MHz, 400MHz and 366MHz.
  • Test frequencies automatically selected by the current test flow. Selected frequency can be optionally changed interactively by the user.
  • Maximum test frequency of 866MHz.

DDR2 Test Parameters
  • Trcd setup of 2, 3, 4, or 5.
  • CAS Latency (CL) setup of 2, 3, 4, 5, 6. (Note: Not all modules support CL=2 and 6.)
  • Additive Latency (AL) setup of 0, 1, 2, 3, 4.
  • Write Recovery (WR) of 2, 4, 5, 6.
  • OCD control of None, 50ohm, 75ohm, and optional 150ohm.
  • Burst Length of 4 or 8.

Addressing Capability
  • 16 Rows and 12 Columns addressing. Up to 8GB modules can be tested. Test support is added as larger modules are introduced to the market.

VDD Setup
  • Uses digitally controlled state-of-the-art switching power supply for Vdd range of 1.5V to 2.2V.
  • Voltage automatically defaults based on frequency to 1.8V-1.9V.
  • User has interactive control of the wider range.

Data Bus Width
  • x64 to x72 bits (Parity/ECC).

SPD Programming
  • Edit/program/save SPD data, unlimited SPD files
  • Production Mode for automated SPD programming
  • Convenient SPD Wizard

Upgrades
  • Free firmware and PC software upgrades via the Internet
  • Optional DDR2 converter/adapters are under development for a wide range of DDR2 memory formats

Test Socket
  • Yamaichi 240-pin test socket, with rugged latches for easy insertion and removal of the modules.

Operating Temp/Humidity
  • 3C to 32C (40 F to 90 degrees F), 20% - 80% non-condensing

Dimension/Weight
  • 7" x 2.6" x 2.1" (W x L x H)/1 lb (3 lbs shipping weight)
  • 17.8cm x 6.6cm x 5.4cm (W x L x H)/.45kg (1.4 kg shipping weight)
  • NOTE: These dimensions do not include the RAMCHECK base tester on which this adapter must be mounted.

Warranty
  • 1-year limited warranty

Please ask for part number INN-8668-15.

Product operation and specifications are subject to change without prior notice.

Some customers may want to build their own adapters for unique memory formats not supported by RAMCHECK. This may require special firmware customization, provided at additional cost. Please review this application note for more information.
