The D-4550 has a Socket 478. Use P-4 Northwood 512k cache processors. CPU max is a 3.06/533 P4, 512k You cannot use P-4 Prescotts, 1mb cache, or the 256k Celeron-D, no 800MHz FSB, on the D-4550 motherboard.

No 3 prong fan connectors on the 4550 mobo. Yes, buy the heatsink from Powerleap and use the exsisting proprietary Dell case/processor fan. 2. Can you please tell me the 1GB RAM sticks(brand/model) that work with the 4550 mobo 100,000% so that I might have a max of 2GB? www.crucial.com and use their memory selector/scanner. Note the limits on memory the D-4550 will support. Not certain if the D-4550 will support a 1gb module. 3. What is the highest watt Dell power supply(more than 350) Dell makes that will work with my 4550 mobo? Dell does not make larger than a 250w for your system, You will need to buy an aftermarket power supply as you want a 350w + unit. For a D-4550 compatible 410w power supply go here, http://www.pcpowercooling.com/products/power_supplies/selector/ This is my WoW(world of warcraft) PC so I want to max it out so I can buy a better video card than the one I have in it now(agp/geforce6200oc/256mb) so that I can turn up the video settings in gamehigher than they are now.
