It doesn't surprise me that Euwe got these results. I have two 4400s here right now, and each came with P4 1.6ghz. The published CPU ceiling is 2.4ghz. I upgraded one to 2.4ghz, and the other with a 2.8ghz that I totally expected to come up as a 2.4. Well, it comes up as a 2.8! (The latest bios release for the motherboard probably supersedes the technical nomenclature published by DELL at the time the units were produced. Also, I'm not sure that 1gbt DDR modules were even available at the time - so two slots with a period limit of 512mgs per module translated to a limit of 1gbt total capacity.)
Now that Euwe has tried this trick with the RAM, that I never would have even thought to try, and it works, along with the 7200 RPM 60gbt drives I replaced in each unit, some salvaged DVD-RWs and the aforementioned processors, these 10 year old computers now seem viable as very capable business machines. I wouldn't be a bit surprised if the AGP x4 slot now supported an AGP x8 as an AGP x8!
I would also know how to work this memory and CPU "trick". I just recently bought Corsair DDR 400 1 GB (2 X 512MB). It will arrive Saturday, and I will try to instal it. If I can get more memory out of my computer, I am very interested. In regards to the CPU, where can you fin a reasonably priced new CPU. Everything i see is around $200, and for that money, I might as well by a new system. I know the CPU is socket 478, but places like New EGG and Tiger Direct do not have much to choose from. Any advice is great. Oh, I also want to upgrade the video card, and I see that it is a AGP X4, so is that the only requirement I should be looking for? This computer is still working on PCI slots, right?
