Dell Vostro 420 upgrade kit

This 4 GB kit contains two 2 GB DDR2 800 MHz DIMMs built for the Dell Vostro 420 tower. The unbuffered non-ECC modules run at CL6 timings with 1.8 V voltage. System-specific validation guarantees they will be recognised by the motherboard without manual configuration.

Matched pair improves throughput

The two sticks form a dual-channel pair that doubles memory bandwidth over a single module. Each DIMM uses 64M×8 major-brand chips in a 2Rx8 organisation for stable operation at PC2-6400 speed. No heat spreaders are fitted, keeping the profile low for tight tower clearances.

Simple 240-pin installation

Insert each module into the 240-pin DDR2 slots until the retention clips click; the Vostro 420 has four sockets supporting up to 8 GB total. Buyers who need more than 8 GB or who use a different Dell model cannot use this kit.

Soalan tentang produk ini

Will the CL6 timing on these DDR2 800 modules require any future timing adjustments or replacement?

The CL6 6-6-6 timing is fixed on these unbuffered DIMMs; no user adjustment is needed and the modules do not degrade timing-wise under normal use.

What limit appears first when the Dell Vostro 420 runs these two 2 GB sticks at full load all day?

The system maximum of 8 GB across four sockets is the hard ceiling; with only 4 GB installed you still have headroom before hitting that cap.

How much heat and power do the 1.8 V DDR2 6400 sticks generate during continuous operation?

Each module runs at the standard 1.8 V for DDR2 800 without a heat spreader, so thermal output stays within normal DDR2 limits for a tower chassis.
