Ok so I have a dell dimension 8400(You dont have to tell me I know they are not good for upgrading). But anyways its getting a lil old and I was thinking bout upgrading it then in a bout a year or so I wanted to give it a go at a custom built machine. Basically what I am working on now is adding RAM, a new video card, a bigger faster hard drive. Then I started Looking at upgrading the CPU and found out that it might not be possible. A friend of mine told me and I quote "The Pentium 4's were at the end of one Socket generation (478) and the start of another (775), and the CPU you have uses the latter (going off the 2MB L2 cache), meaning it might be possible to upgrade to a Core 2 Duo (higher end Duos and any Quads will probably be out of the equation, however)." So I was wondering if this is true and if so can anyone point me in the right direction of a Duo that would be in "the equation". And if not maybe a mobo that would be compatible and again I know that this is a long shot from what I have read. But anyways heres some specs and any help would be appreciated.

Solution


The 945 chipset version 2 was the earliest to support C2D 65nm. Intel 955 was released at the time of C2D release. But yeah, anything before 955 or a few version 2 945's that appeared did not have proper voltage regulation for 65nm C2Ds. Need P35 for a 45 nm C2D to run (properly). Again all about voltage regulation.

Edit i945 supports Pentium D dual core CPU's, but the 925 does not.

Options for OP as far as a Pentium 4 775 upgrade:

If you are looking at adding more RAM, a Video Card, a Hard drive and a processor, all of which you are spending money on an old outdated Dell system. You will still have an old outdated Dell system. You likely will need a PSU if you upgrade to any mid-range video card as well.
Now, if you are going to do all that, you realize that all need is a motherboard and case and you have a completely new build, without being limited to buying old slower parts that will work with your Dell board. I think I would try to come with just a little more cash and move in the completely new direction rather than dumping a wad into the old machine. It won't cost you much more than you are planning on spending now, not much at all.

Thank you everybody for the input.





Yea I understand that. I'm just trying to get another year or so out of my Dell. If i could of upgraded the processor within reason then I would of but since it doesnt look to be very logical to do so I wont. I was thinking that I could do a few upgrades as far as RAM and Hard drive and video card then in a year, like you said, just get a mobo and a PSU and build new. But what you said got me thinking, is DDR2 going to be obsolete within the next couple of years? Sorry to go off topic.

Ok so just to make sure I got this right, judging by your link my only option is another P4 just with a higher core speed? Which is pretty much waste of time and money right?
 



Yes, I would say that in less than a year, DDR2 motherboards will be hard to find at all, new anyway.
