Question

Intel CPU packaging question BGA OR/AND PGA

Asked by: hitcher_lt

Hi,

I want to find out which processor packaging type will fit the chipset. I have tried couple of different utilities to identify CPU type including Intel one. But all of them have this under packaging FCPGA/FCBGA. Does this mean that motherboard supports both types of packaging? I'm trying to upgrade CPU on my laptop and I am little confused here. Thanks for your help.

First, we need to know which CPU you have. There are at least 3 different sockets for Core 2 duo mobile CPUs.

its T7250 socket P

 

by: willcompPosted on 2009-10-07 at 15:15:59ID: 25520676

Well -- you just answered your own question. It's socket P (which is a PGA socket). Only Socket P CPUs will fit. Both Socket M and Socket P have 478 pins but the pins are arranged differently.

 

by: hitcher_ltPosted on 2009-10-07 at 15:29:17ID: 25520810

Processor is T7250,  I think it is a socket P I am not sure, sorry. And Intels diagnostic utility same as Everest or CPU-Z says that packaging is FCPGA/FCBGA. How do I identify which is it exactly and back to the original question can motherboard support both types FCPGA/FCBGA of packaging?

 

by: willcompPosted on 2009-10-07 at 15:48:46ID: 25520972

All of the T7XXX CPUs are socket P. No you cannot interchange PGA and BGA CPUs nor can you install a PGA CPU which requires a different socket. As previously stated, you are limited to Socket P CPUs. In addition, the CPU must be supported by the BIOS and chipset.

 

by: hitcher_ltPosted on 2009-10-08 at 02:23:32ID: 25523386

Ok, I am attaching Intel's utility CPU report screenshot. Can you identify from that which packaging is it? As for instance CPU T7800 (this is the CPU I want upgrade to) has both types of packaging available. Both CPU's are identical except for the packaging type.
It is kind of contradicting to your statement that "All of the T7XXX CPUs are socket P"

I owe you a word of explanation. The reference I used was quite obviously incorrect and I know of no way to definitively determine which socket you have other than physically inspecting the socket or CPU. Maybe someone else will have another method.

 

by: hitcher_ltPosted on 2009-10-08 at 15:25:19ID: 25530856

thanks for the explanation.

Socket-P is the same as micro FCPGA.  FCPGA is Flip Chip Pin Grid Array, and FCBGA is Flip Chip Ball Grid Array.  FCPGA has pins for contact and is typically used in sockets, while FCBGA has balls for contact and is typically soldered to the motherboard.  FCBGA can be used in sockets, but requires an adapter.  You should visually inspect your motherboard to see if it uses a socket or not - if it doesn't, you won't be able to change it.
