RAMCHECK DDR2/DDR1 Key Features Tests and identifies 240-pin PC2-5300/4300/3200 DDR2 modules at true clock speed. Upward compatible to test PC2-6400 module at reduced speed. Supports Registered, Unbuffered and ECC DDR2 modules up to 8GB. Tests and identifies 184-pin PC466/433/400/333/266/200 DDR1, 4GB+ 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. RAMCHECK DDR2/DDR1 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 Relative Refresh/Cell Leakage Relative Voltage Spikes Temperature Stress Test Auto-Loop Test Module is endlessly tested with different pattern bits Detects pattern sensitivity problems Excellent for burn-in procedure Addressing Capability Maximum 16 Row/16 Columns addresses. Currently up to 8GB modules can be tested. Test support is added as larger modules are introduced to the market.
