Processor question I really dont know.

I honestly dont know if this can be done I would think not but I have to ask. I have a P4 Alienware with a socket 775 now my question and I imagine you know where I am going with this, but can you swap it for a 775 Core 2? Thats my question, thanks everyone.

 

No........

 

Not a chance, they are completely different sockets and require totally different chipsets.

 

ok good to know because I asked on yahoo and the only guy that responded said it depends on my motherboard. I appreciate the definitive answers. Thanks again.

 

haha @ yahoo answers...you came to the right place

 

How about a different twist can you upgrade the cpu on laptops at all? For example could I go to newegg and get a 3.8ghz P4 and put it in my laptop?

 

Sometimes, rarely, but i belive you "can". That exact speed may not be available though...

 

You can replace it with any Socket 775 processor as long as the BIOS supports it (most likely will).

 

Im not sure I completely agree with that answer. Correct me if im wrong, but if these two processors weren't inter-swappable (Socket 775 Intel P4: Socket 775 Intel Core 2 Duo), would they not be two completely different sockets alltogether? Isn't that why processors are all made with different sockets?

I COULD see there being a problem if the BIOS doesnt support it but... idk...

Im not trying to stirr up anything but to my understanding isnt this the way it goes? Im under no condition a genius so please feel free to correct me .

They are completely different sockets.

P4s are socket 775

core duo and core 2 duos are socket M

newest core 2 duos (santa rosa platform) are socket P

 

What is the chipset used? If the Alienware is using a desktop P4 (not the P4 M) then you CAN replace it with a Core 2 Duo since they both use the same socket, Socket T aka LGA 775 - as long as your BIOS supports it. If it's a P4 M or an older P4, this uses Socket 478, which was phased out.

adinu, you are confusing desktop and mobile platforms. Socket M and P are for the mobile line and both have 478 pins.

 

A core 2 duo is not socket T aka LGA 775...

Like I said before, P4s are either socket 478 or 775

Core duos are socket M

Core 2 duos (santa rosa) are socket M

 

I hate to do this like this, but its time to settle this "socket" argument.

That is a link to about a dozen different socket 775 core 2 duo's listed on Newegg. Yes, they come as socket 775, so to answer the original post question; Yes, an upgrade from a 775 p4 to a 775 core 2 duo should be possible, and the only bottleneck you will need to worry about is front-side bus speeds. Possible? yes. Worth it? depends on your Motherboard.

Aaack...confused. So much for a definitive answer.

That link is returning zero items that match the search, by the way.

 

haha I almost feel sorry for even asking but I too went to newegg and saw a lot of 775 core 2 processors thats why I asked. Maybe I should get on the phone with intel!!

 

OK, pay attention, class!!

Intel make 2 ranges of their chips, one range for laptops, one for desktops.

Not counting budget ranges, the mobile chips are:

P4-M - socket 478
Pentium-M - socket 479
Core Duo/Core 2 Duo - socket M
Core 2 Duo Sanata Rosa gen. - socket P

Mobile chips after P4 have 479 pins.

The desktop chips are:

Pentium 4 - socket 478
Pentium 4 - socket 775
Pentium D - socket 775
Core Duo/Core 2 Duo - socket 775

(yes, I know I missed out Pentium Dual Core)

Desktop chips that are socket LGA775 have 775 pins.


So: there are socket 775 Core 2 Duos, they are desktop cpus. Desktop motherboards that support Core 2 Duos often support Core Duo, Pentium Dual Core, Pentium D and Pentium 4 as long as they are socket 775.

If your motherboard was designed for Pentium 4 Socket LGA775 chips, it MIGHT support Core 2 Duos. They will fit in the socket but the chipset/BIOS may or may not support Core 2 Duos depending on when the motherboard was made, what other chips were sold with that machine and whether there have been updated BIOS made for the board to allow it to support Core 2 Duos and other newer chips if it was not designed to do so in the first place.

So: a Core 2 Duo will fit, but it might not work properly. Find out if any more pwoerful chips were ever sold with your exact model. Also check for the latest BIOS and any release notes that go with it. Check the net to see if anyone else has made a successful upgrade with this chip. You could also contact the manufacturer and ask them.

Right. Sorted.
