Compatible DDR2 Upgrade for Dell Studio 540/540S

This kit provides 4GB of DDR2 memory in a matched pair of 2GB modules. It is built specifically for the Dell Studio 540 and Studio Slim 540S desktops. The modules use a standard 240-pin DIMM form factor and operate at 1.8V without ECC or buffering.

DDR2 800MHz Speed and Motherboard Limits

The memory runs at DDR2 800 (PC2-6400) with CL6 timing. System performance will not exceed the DDR2 interface bandwidth or the maximum memory capacity supported by the Dell motherboard. The platform accepts up to 8GB across four sockets, so this kit fills half the available slots.

Two-Module Kit Determines Upgrade Path

The product ships as a 2×2GB kit, delivering 4GB total capacity. Buyers who want more storage than 4GB must add additional modules or replace this kit entirely. Builders who need a single high-density stick or a different pin layout cannot use this package.

Questions about this item

Should I choose the 4 GB kit or add a second kit to reach the 8 GB maximum?

The Dell Studio 540 and 540S support up to 8 GB across four slots, so the 4 GB (2×2 GB) kit fills half the slots; adding a second identical kit reaches the maximum.

What does the PC2-6400 rating mean once the modules are installed?

PC2-6400 indicates a peak transfer rate of 6400 MB/s at 800 MHz, so the memory runs at DDR2-800 speed with CL6 timing in your system.

Will these 240-pin DDR2 DIMMs work in the Studio 540 and 540S motherboards?

Yes, the 240-pin DDR2 DIMMs are designed for the Dell Studio 540 and Studio Slim 540S, matching the required unbuffered non-ECC specification.
