System-specific DDR2 upgrade kit

This 4GB kit contains two 2GB DDR2-800 modules built for the Dell Vostro 320 all-in-one. Each stick is a 240-pin unbuffered DIMM running at 1.8V with CL6 timings. The matched pair installs directly into the system's two memory sockets.

DDR2 800 platform ceiling

The Vostro 320 all-in-one accepts a maximum of 4GB across its two DDR2 slots. This kit fills both sockets and reaches the platform limit. Any additional capacity would require a different motherboard or memory standard.

Full 4GB capacity for legacy workloads

The 4GB total handles period-correct operating systems and everyday applications from the DDR2 era. Memory-intensive modern software or heavy multitasking will exceed the available headroom. Buyers needing more than 4GB must choose a newer platform.

Questions about this item

Should I pick the 2 x 2 GB kit or a single 4 GB module for the Dell Vostro 320 All-In-One?

The system has two DIMM slots and a 4 GB maximum, so the 2 x 2 GB kit fills both slots and reaches the limit; a single 4 GB module would leave one slot empty but cannot exceed the 4 GB ceiling.

What does the 800 MHz rating deliver inside the Vostro 320?

The modules run at DDR2-800 with CL6 timing and 1.8 V, giving a peak bandwidth of PC2-6400 that the Vostro 320 chipset can utilise without overclocking.

Is the 240-pin DDR2 interface compatible with the Vostro 320 motherboard?

Yes, the kit uses standard 240-pin unbuffered non-ECC DDR2 DIMMs, which match the Vostro 320 All-In-One memory slots and the board's supported PC2-6400 speed.
