System-specific DDR2 kit for Dell Vostro 1720

This 4GB kit contains two 2GB DDR2 800MHz SO-DIMM modules built to the PC2-6400 standard with CL6 timings. It is designed as a direct memory upgrade for the Dell Vostro 1720 notebook using major-brand chipsets.

Suits owners restoring a Vostro 1720 to working

Buyers whose laptops accept only a single module or require ECC registered memory should look elsewhere. The kit will not fit systems that use a different pin count or voltage, nor those needing the full 8GB maximum capacity this model supports.

200-pin DDR2 SO-DIMM form factor decides fit

Each stick uses the 200-pin DDR2 SO-DIMM interface running at 1.8V with unbuffered 2Rx8 organisation. Verify that the target notebook matches this exact specification before ordering.

Questions about this item

Should I choose the 2x2GB kit or a single 4GB module for my Dell Vostro 1720?

The Vostro 1720 has two memory sockets and supports up to 8GB total. This 2x2GB kit fills both slots for dual-channel operation, which improves bandwidth over a single module.

What does the 800MHz speed rating deliver in actual use?

The modules run at DDR2 800 (PC2-6400) with CL6 6-6-6 timings at 1.8V, providing the rated bandwidth and latency when installed in a compatible Vostro 1720.

Will the 200-pin DDR2 SO-DIMM interface limit performance on this notebook?

The 200-pin DDR2 SO-DIMM form factor matches the Vostro 1720 slots exactly; the memory controller in that platform caps the practical throughput at the DDR2 800 specification.
