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.
