Socket M 478/479?

I live in my moms basement
I wear boba fett costume for pjs

 

Socket 478 is for Pentium Ms (478 pins)

Socket 479 is for the new Core Duos (also 478 pins, but arranged in a different order so that people don't put in the wrong cpus, thus is called socket 479 even tho it has 478 pins)

As long as you are getting the right cpu (core duo) then don't worry what the people decide to call the socket, it's all the same. Just don't put a Pentium M in a Core Duo socket and the other way around.

 

Thanks. That makes no sense, but in a way makes perfect sense. Like a lot of stuff in the computer world. Hey wait youare rocking an AMD! Can I trust you!

wait
then there is this thread

which says socket 479 and socket m are different things. Socket M actually having 479 pins, while socket 479 has 478 pins.
Um......yeah.

 

Unfortunately Adinu is incorrect.

Intel have a very annoying habit of having both 478 and 479 pin versions of their CPUs. The intel prcessor spec finder can help identify which ones are which here:

http://processorfinder.intel.com/Default.aspx

The Celeron-M 420 you have is listed as 478 Pin. The Celeron-M 400s are based on the Core Duos so a Core Duo (like a T2300) would make a good upgrade. Be sure to look on the utility I linked and look up the cpu model number and check it is compatible.

 

ok wow, now I am really confused.
so my "mPGA 479m, Celeron M 420. " is socket 479 which has 478 pins.
now what I need to figure out is which processors at newegg are compatible.
Would that be the whole T2000 series?
Would the T7200 work if its 478pin?

 

I checked the Intel thing you linked to. But it does not specify my actual current chip?! It is educational as eff to see that the same models come in different packages/pinouts. Go figure.

 

Please enlighten me with the correct information then, and show me where I was wrong.

 

ok I went back just now and I did find my chip. Before it was pointing to socket 775 when I chose celeron 400 series. I instead looked under celeron M this time and found it. It still does not say which socket. Only number of pins. ANd as pointed out above there are 2 flavors of 478 pins!

 

Exactly. Both sockets have 478 pins, but they are arranged in different orders. I believe one is called socket m, and the other is socket p.

 

hmmm interesting
well I went all over the lenovo website last nite and found documents listing parts for their notebooks motherboards There are about 4 dozen versions of my notebook, but only 2 motherboards. By cross referencing the motherboards against the cpu part numbers I came up with this list of possible CPUs that seem to fit.
T2060
T2300E
T2400
T2500 (its a maybe)
T5500
T5600
T7200
does this sound right?

 

Yes, but if ur upgrading from a cd to a c2d, you might need a new bios. Other than that, all those cpus are 100% pin compatible.

 

I actually already checked the bios thing. Apparently the same Bios is used across the entire Lenovo 3000 line. The did just rev it up to support the funny number newer CD and C2D which I think are the 2350 and 2250.
correction
T2060&T2350 CPU.

 

Here's some info to clear up the socket names:

Socket 478: 478 Pins, Supports Celeron, Celeron D Pentium 4 and Pentium 4 EE.

Socket 479: 479 Pins, Supports Celeron M and Pentium M

Socket M: 478 Pins, Supports Core Solo, Core Duo, Dual-Core Xeon, Core 2 Duo (T5x00, T7x00, Merom), and Celeron M (Yonah, Merom)

Socket P: 478 Pins, Supports Core 2 Duo

 

okay one more q if anyone is listening.
On the link above to the cpu identifier
my chip comes up as socket m 478 pin right?
All the core duos and core 2 duos are listed with Micro-FCBGA or Micro-FCPGA
which is pretty unspecific. Any wisdom?

 

bga means the cpu is soldered onto the motherboard.

pga means its a drop in cpu.

Most likely, their all pga, meaning they can be removed. Only low voltage ones are bga.

 

You posted that Pentium-Ms have 478 pins and Cores have 479. This is incorrect. Had you read my post and gone to the link I provided you would see that Inetel's current and past mobile cpus back to Centrino have both 478 and 479 pin configurations. That is, each chip has both configurations and this is why it is so confusing.
