Compatible ThinkPad T42 upgrade

This 2GB kit uses two 1GB DDR333 SO-DIMM modules built for the IBM Lenovo ThinkPad T42 Pentium M series. It matches the 200-pin DDR1 PC2700 specification required by models 2373, 2374, 2375, 2376, 2378 and 2379. The memory is unbuffered, non-ECC and runs at CL2.5 timing.

Passive thermals and low voltage

Each stick operates at 2.5V without a heat spreader, relying on the notebook's internal airflow for cooling. The DDR333 speed and standard CAS latency keep power draw modest during typical office workloads. No active cooling or additional voltage is needed for normal operation.

Two matched modules in the box

The package contains a pair of 1GB sticks so the T42 can run in dual-channel mode where supported. Computer Memory Solutions backs the kit with a limited lifetime warranty when purchased directly from them. Product appearance may vary from the reference photograph.

Preguntas sobre este artículo

How do I install the 200-pin SODIMM modules in a ThinkPad T42 without damaging the contacts?

Power off the laptop, remove the battery, open the memory door, align the notch on each module with the slot key, insert firmly until the gold contacts are no longer visible, then press down until the side clips click into place.

Will the 2.5 V DDR333 modules need any firmware updates or periodic re-seating to stay reliable?

No firmware updates are required; the modules are unbuffered non-ECC DRAM with no moving parts, so only occasional dust removal from the slot with compressed air is needed if the laptop is used in a dusty environment.

What thermal or electrical limit appears first when the 2Rx8 chips run at 333 MHz continuously?

The 2.5 V supply and CAS 2.5 timing set the electrical envelope; sustained loads will hit the DDR333 bandwidth ceiling before any thermal throttle point on these unbuffered chips.
