System-specific DDR1 kit

This two-piece kit provides 2 GB of DDR1 memory for the Dell Inspiron 9100. Each module is a 200-pin SODIMM rated at DDR400 speed with CL3 timing. The upgrade targets owners of that notebook who need the maximum supported capacity.

Sustained-load behaviour

The unbuffered, non-ECC modules operate at 2.6 V with a 3-3-3 timing profile. Under continuous workloads the Major Brand Chipset maintains the specified DDR400 data rate without throttling. The dual-rank 2Rx8 organisation distributes accesses across both sticks for steadier throughput.

DDR400 interface limits

The PC3200 standard caps bandwidth at 3200 MB/s per channel. The notebook’s two sockets accept a maximum of 2 GB total, so no further expansion is possible. Builders needing more memory or a faster memory type must choose a different platform.

Questions about this item

How much heat and power does the 2.6V DDR400 kit draw when the Inspiron 9100 runs all day?

Each module operates at 2.6V without a heat spreader; typical DDR1 SO-DIMM power at this voltage is low enough that the laptop’s existing cooling handles continuous use.

What must the buyer already own for this 200-pin SODIMM kit to work?

A Dell Inspiron 9100 with two free 200-pin DDR SO-DIMM slots; the notebook’s maximum supported memory is 2GB, which this 2 x 1GB kit fills completely.

Will the CL3 400MHz modules run correctly alongside any original memory left in the Inspiron 9100?

The kit is guaranteed compatible with the Inspiron 9100; the system will operate all installed modules at the supported DDR400 CL3 timing.
