Swapping out 2.0GHz P4 for 2.8GHz P4?

Ok I have an old Dell Dimension 4500 with a 2.0GHz P4 and I want to update this PC a bit with some RAM and a 2.8GHz P4(both are Northwood). According to everest under the motherboard tab the fsb effective clock is 400MHz, but under the chipset tab it says it will support 400 or 533. (Northbridge is Intel brookdales i845E) Will the chip plug and play?


So I guess I will have to find a decent socket 478 cooler if this works? All it currently has is a heatsink attached to the CPU with some tin foil looking thermal tape with no fan, and the only fan in the case is an 80mm exhaust fan in the back.

More about : swapping 0ghz 8ghz

After looking up your pc it looks like the 2.8GHZ p4 was an option which means the bios should know how to handle it, if not you will need to update the bios. Getting a heatsink is a good idea, but it may be pretty hard to find.

Heatsinks for 478 are plentiful on ebay, I have even seen a couple very good aftermarkets for it on there.

However I did come across this P4 HT and motherboard combo I just wonder if it would plug and play...

I wouldn’t plug and play because they are different brands. The os knows what board it is running on, so you would have to have a generic copy of windows to change out the board.

You may need to swap out memory, as a P4-2Ghz uses 333mhz memory while the P4-2.8Ghz will use 400Mhz memory.
