Kit for Dell Dimension 4550

This 1GB kit contains two 512MB DDR333 modules built specifically for Dell Dimension 4550 desktops. It uses 184-pin unbuffered DIMMs with a CAS latency of 2.5 and operates at 2.5V. The kit is designed to match the original system requirements without configuration changes.

DDR333 bandwidth and density limits

The DDR333 standard caps transfer rates at 333 MT/s and this kit reaches 1GB total across two slots. Each module provides 512MB, so the system cannot exceed this density per slot. Builders needing more than 1GB with this speed grade must look beyond DDR333 technology.

Major brand chips without heat spreaders

The modules use major brand chipsets on standard green PCBs and have no heat spreaders attached. Their low-profile design fits the tight clearance around the Dimension 4550 motherboard slots. Gold edge connectors on the 184-pin interface resist oxidation during long service intervals.

Questions about this item

Should I buy the 1 GB kit as two 512 MB sticks or look for a single 1 GB module?

The Dell Dimension 4550 has only two memory sockets and a 2 GB maximum. Using the 2 x 512 MB kit fills both slots and leaves room for a future upgrade to 2 GB with two 1 GB modules.

What does the DDR333 (PC2700) rating mean for everyday use in this Dell?

The modules run at 333 MHz with CL2.5 timing, matching the system bus of the Dimension 4550 so the memory controller operates at its native speed without down-clocking.

Will the 184-pin DDR333 DIMMs work in the Dimension 4550 without BIOS changes?

Yes. The kit is built to the 184-pin DDR SDRAM standard at 2.5 V, unbuffered and non-ECC, which is the exact specification the Dimension 4550 requires.
