Fastest processor for Dell Dimension 4550

I have got a Dell desktop system and my model is Dimension 4550, my system is been quite old now and has currently installed intel Pentium iv processor. I am looking to upgrade the cpu on my Dell computer but I am a little puzzled as to what sort of processor I can upgrade to. It at present has a 2.4ghz P4 cpu with the 533mhz bus and has 478 pins as far as Right now I am stuck at northwood processors that has the 533mhz bus , now I want my processor ot be replaced with such a processor that makes my system the fastest , so please suggest me a processor that is really fast and increase the performance.

Yes you can definitely do it , but before that you will have to check a lot of things , then on the basis your BIOS version, a 2.8/3.0 would be the accuarate 478 processor your 845PE would maintain. Your trapped with a very old chipset supporting 4 x AGP video card and work on more than 300 mhz and a RAM. Equivalent to 512 MB . I would not spend much time if I was in your place

Well, If you ask my opinion do not really do any such major change with the computer that would merit a brand new system . With all the application and updates and stuffed software that come around over the last few years, you will need a small promote to make things a little more snappier. According to me simplest way clearly is to put in the faster processor and/or add the highest ram. I by now have 1gb of ram in my system so the only other thing is the processor change .

I checked the Dell system specifications your system is 2.8 and 3.06 compatible. These a 800mhz fsb capable processors. Like I I have told , you may have to upgrade to the newest BIOS version to hold the processors, clearly I do not know that for positive. I am not sure if the 845 chains with Prescott processors. It is s getting hard to position a Northwood, the 478 is very old. I have a total 3.0 ghz Northwood P4 800mhz fsb with an ABIT 478 MB and a GB of Kingston PC3200 installed in my cabinet. My cabinet has a 9200 ATI radeon, 80Gb WD IDE improved Hard drive it also has a DVD burner, and floppy drive, windows XP installed. The computer runs perfect. I would put up for sale it to anyone at the rate of 160

The 2.8 and 3.06 Ghz CPUs in query are both 533 bus processors. unluckily, 800fsb CPUs are not well-matched with your dimension system . They also do not matched well with Prescott-based Pentium IV and Celeron Ds on the 533fsb, due to Dell will never updating the BIOS and I do not think it offer this support. It is regretting to say , but you are trapped with 533bus P4s likely be finest to just be cost saving , as the improving step from a 2.4B to a 2.8B is logically irrelevant.
