Pentium 4 upgrade

[jusbigp]

I have an old dell demension E510 it has a socket 775 pentium 4 630 single core processor.
can I upgrade this to a pentium E5400 dual core processor (lga 775) or any 775 dual core processor

It's probably best to ask Dell tech support.

apparently the motherboard only supports Pentium 4 5XX/6XX Processors 2.8-3.8 GHz
so dual core processors are not supported

Well then you better get a new motherboard, If you already have ddr2 may i suggsest this - http://www.ebuyer.com/231358-gigabyte-ga-g41m-combo-socket-775-vga-6-channel-audio-matx-motherboard-ga-g41m-combo?utm_source=google&utm_medium=products

How do you know what an old motherboard will support? I have a HP dx2200MT with socket 775, and I want to upgrade my Pentium 4 CPU. I can't establish the exact model of the motherboard. The HP website has technical specifications but does not give a lot of detail about the motherboard. CPU-Z shows the board as an MSI oa48, but the MSI website does not show that model, or any models ever starting with O.

I'm thinking about a Intel Core 2 Duo E8400 for $99. Any thoughts?
