1GB DDR1 333MHz SODIMM for HP Pavilion dv1000

This module is a 1GB 200-pin DDR1 SO-DIMM rated at 333MHz with CL2.5 timing and 2.5V operation. It is built as an unbuffered, non-ECC stick using major-brand chips in a 2Rx8 configuration. The part targets owners of HP Pavilion dv1000 and dv1040US notebooks who need a direct memory upgrade.

Installation fit and system impact

The stick fits the 200-pin SO-DIMM slot found in the listed HP Pavilion models and requires no BIOS configuration beyond standard detection. Because it is a single 1GB rank, it leaves a second slot free on dual-channel boards for future expansion. No heat spreader is fitted, so clearance inside thin chassis is not affected.

Sustained-load behaviour

Under continuous workloads the module runs at its rated 2.5V without active cooling, relying on the notebook's existing airflow. The CL2.5-3-3 timings remain stable at 333MHz during extended sessions, and the unbuffered design adds no extra latency overhead. Buyers who need ECC error correction or registered buffering for server workloads should look elsewhere.

Questions about this item

Will the 2.5 V DDR1 SODIMM throttle under sustained load without a heat spreader?

The module has no heat spreader and runs at standard 2.5 V; DDR1 at 333 MHz typically stays within thermal limits in notebook chassis airflow.

How much power does the 1 GB PC2700 stick draw when the laptop runs all day?

DDR1 SODIMMs at 333 MHz and 2.5 V generally consume a few watts, producing minimal extra heat or fan noise during continuous use.

Does my HP Pavilion dv1000 need a BIOS update or matching DIMM to use this 200-pin CL2.5 module?

The stick is listed as compatible with the dv1000 and dv1040US series; no extra hardware is required beyond an empty 200-pin DDR SODIMM slot.
