System-Specific DDR2 SODIMM Kit

This 4GB kit contains two 2GB DDR2-800 modules built to Dell specifications for the Inspiron 17 1720 notebook. It uses the 200-pin SO-DIMM form factor and runs at 1.8V with CL6 timings. The kit targets owners of that exact model who want to reach the platform maximum of 4GB.

DDR2 800MHz Interface Limits

The PC2-6400 standard tops out at 800MHz with 6-6-6 latency, so bandwidth is fixed by the memory controller in this notebook. No BIOS option can push frequency higher, and mixing with slower DDR2 modules forces the whole array to the lowest common speed. ECC and registered operation are not supported.

4GB Capacity Boundary

Two populated slots deliver the 4GB ceiling the Inspiron 17 1720 can address, leaving no free sockets for further expansion. Workloads that exceed 4GB of active data will swap to disk, while typical office and legacy applications fit comfortably within this limit.

Questions about this item

Should I choose the 2 x 2 GB kit or a single 4 GB module?

The kit provides two 2 GB SODIMMs, matching the notebook's two slots so both channels are populated for dual-channel bandwidth.

What does the PC2-6400 800 MHz rating deliver in the Inspiron 17 1720?

The modules run at 800 MHz with CL6 timing, giving the maximum throughput the chipset supports for DDR2 memory.

Will the 200-pin DDR2 SODIMM interface fit and run at full speed?

Yes, the 200-pin DDR2 SO-DIMM form factor is the exact slot type used by the Inspiron 17 1720, and the 800 MHz speed matches the platform's native memory bus.
