Maximum RAM for Dell Dimension 4550 is 2 GB

Although many memory sites and even Dell proclaim that the Dimension 4550 has a memory limit of 1 Gigabyte, many will run two 1 GB sticks.

See an article located at http://en.community.dell.com/wikis/desktop/dimension-4550-maximum-memory-2gb-not-1gb.aspx, which led me to attempt to upgrade an old 4550’s memory to 2 Gigs.

While some commenters complained that they could not do so, they didn’t specify whether they had also upgraded to BIOS A08 or if they had the 400 Mhz FSB motherbourd or a 533.

The one I worked with was upgraded to the A08 BIOS and it had a 400 FSB board.  Its original CPU was previously upgraded to 2.8 GHz. The RAM used was 2 two DDR DIMMs of PC 3200 Kingston Value Ram with a clock speed of 400 Mhz.  The Dimension 4550 ran it at 333 MHz.

The only reason I am posting this info here is I had so much difficulty finding something on the net about the problem.  Most posts said it couldn’t be done.
