Dell Precision T3400 memory kit

This 4 GB kit contains two 2 GB DDR2 modules built for the Dell Precision Workstation T3400. It runs at 667 MHz with PC2-5300 timing and CL5 latency. The unbuffered non-ECC DIMMs install directly into the workstation's four memory sockets.

Thermals and power profile

Operating at 1.8 V, the modules draw modest power and produce little heat without a heat spreader. The low voltage keeps system fan noise unchanged during typical workloads. No active cooling is required for normal operation.

Upgrade path and limits

The kit fills two of four slots and raises total memory toward the 8 GB maximum supported by the T3400. Mixing with DDR2-800 modules forces the bus down to 667 MHz. A 64-bit operating system is needed to address more than 4 GB, and installed memory above 4 GB may be reported as 3.5 GB or less depending on configuration.

Questions about this item

How do I install the 240-pin DDR2 DIMMs in the Dell Precision T3400 and what step is often missed?

Power off, open the case, align the notch on each module with the slot key, press firmly until both side clips click, then verify in BIOS that both 2 GB sticks are seen at 667 MHz; the step often missed is seating the second stick fully so both clips engage.

What maintenance or replacement will the CM256645300DIMMDR kit need later?

No routine maintenance is required; keep interior dust-free, and replace only if a module fails — the kit carries a limited lifetime warranty from Computer Memory Solutions.

What limit appears first under sustained use with this 4 GB DDR2 667 MHz kit?

The 4 GB capacity ceiling is reached before thermal or voltage limits; a 64-bit OS is needed to address the full amount, and mixing with DDR2-800 modules will force the bus to 667 MHz.
