4GB 2x2GB DDR2-667 PC2-5300 RAM Kit for Dell XPS 400 - Reliable

In this review the focus is on a straightforward memory upgrade: a 4GB kit made up of two 2GB DDR2-667 modules specifically for the Dell XPS 400. The bottom line is simple - if you are running an XPS 400 with limited memory and want a reliable, drop-in upgrade that restores multitasking and responsiveness, this kit delivers. The reviewer found it to be a genuine, well matched pair that installs cleanly and is backed by a limited lifetime warranty, making it a practical choice for owners who need a no-friction memory boost.

Key Features

• Form factor: The 240-pin DDR2 design fits the Dell XPS 400 memory slots for an uncomplicated physical installation.
• Performance: DDR2-667 (PC2-5300) speed provides a noticeable improvement in application switching and general responsiveness over lower-speed modules.
• Capacity: Two matched 2GB sticks give a total of 4GB, which is a sensible upgrade for older desktops that were often shipped with 512MB or 1GB.
• Compatibility: The kit is specifically designed for the Dell XPS 400 so users avoid common mismatches and timing issues.
• Warranty: A limited lifetime warranty offers peace of mind against early failures or DOA modules.
• Voltage and timings: Standard 1.8V and CL=5 timings keep the modules within expected operating parameters for legacy systems.

Who It's For

This kit is best for Dell XPS 400 owners who want a targeted, reliable upgrade without the fuss of compatibility hunting. It suits users running older Windows installations who need more headroom for web browsing, document work, light photo editing, or improving OS responsiveness.

It is not intended for modern gaming rigs or systems that require ECC, registered, or higher-speed DDR variants; buyers who need cutting-edge performance, error-correcting memory, or modules for non-Dell platforms should look elsewhere.

Pros & Cons
