Intel Mobile Processor Compatibility Guide

Intel Mobile Processor Compatibility Guide

Introduction

A few months ago I tried to perform processor upgrades on a relative's Dell Inspiron 1150. The 1150 had a Socket 478 Mobile Celeron that ran hot and performed poorly. After doing some cursory research I thought I knew what I was doing and bought a Socket 479 Pentium M. Needless to say, it didn't fit. So I did a bit more research and found myself mired in the rather confusing world of mobile sockets. And it took me a while to figure things out. Recently, after reading a few threads concerning processor upgrades, I figured I'd make a guide. It'd be fun. It couldn't be that hard.

So this is my first guide on NBR and while it's more of a chart and may or may not be terribly helpful, it should, at the very least make a reasonable reference for those of you interested in upgrading mobile Intel processors.

About This Guide

This guide does NOT list every Intel mobile processor. Processors older than the Pentium 4-M and associated Celerons have been omitted. Some chipsets supporting the Pentium 4-M, Mobile Pentium 4 and associated Celerons may also be missing.

Sockets

Current Intel mobile processors can fit one of four mobile sockets. These are Sockets 478 (N), 479, M and P. Laptops utilizing Sockets 478 and 479 are no longer being produced and laptops utilizing Socket 478 are becoming few and far apart. All four sockets have 478 pins in flip-chip pin grid array and are incompatible with each other.

Processors

This guide lists all Pentium 4-M, Mobile Pentium 4, Pentium M, Core Solo, Core Duo, Core 2 Duo, Mobile Celeron and Celeron M chips. Processors under a particular brand are listed according to core. Each processor entry is followed by its clock speed (in MHz), its L2 cache size (in KB) and its front side bus speed (in MHz). All processors listed under a particular socket are mechanically compatible with that socket.

Chipsets

This guide lists mobile 845, 852, 855, 910, 915, 940, 943, 945, 960 and 965 chipsets. As a rule of thumb, chipset names including a G usually ship with integrated graphics and chipset names including a P always ship with dedicated graphics. Processors listed under a particular brand are followed by compatible chipsets. Each chipset entry is followed by its front side bus speed (in MHz). Not all chipsets listed under a particular brand of processor will be compatible with each and every associated processor.

Compatibility

In order for a particular processor to be compatible with a particular laptop; (1) the processor must be physically compatible with the laptop socket, (2) the laptop chipset must support the processor, (3) the chipset front side bus speed must match the processor front side bus speed, (4) the laptop BIOS must support the process.

This guide does not guarantee compatibility. Laptops are immensely complicated machines and sometimes will not be compatible with a particular processor even if the four aforementioned conditions are met. Sometimes, the opposite will be true. The most accurate way to use this guide may be to find out what WILL NOT work rather than what will work.

Socket 478

Socket 478 supports Pentium 4-M, Mobile Pentium 4, Mobile Pentium 4 HT and associated Celerons based on Northwood and Prescott cores. These chips were produced from 2002 to 2005.

LV and ULV

Low-voltage and ultra-low-voltage processors are usually soldered to the motherboard and therefore unassociated with a particular socket. You will unlikely be able to remove or replace a low-voltage or ultra-low-voltage processor.

Notes on the GL960

08/04/05

As of this update, the GL960 only has official support for Socket P Celerons. Manufacturers, however, have been shipping the GL960 with Socket P Pentium Dual-Cores. The GL960 will certainly work with the following processors:

Celeron M 530 1733 1024 533
Celeron M 540 1866 1024 533
Celeron M 550 2000 1024 533
Celeron M 560 2133 1024 533

Pentium Dual-Core T2310 1466 1024 533
Pentium Dual-Core T2330 1600 1024 533
Pentium Dual-Core T2370 1733 1024 533

As of this update, several board members have reported successful uprades to 667MHz FSB and 800MHz FSB Socket P Core 2 Duos and none have reported unsuccessful upgrades. The GL960 will probably work with the following processors:

Core 2 Duo T5250 1500 2048 667
Core 2 Duo T5450 1667 2048 667
Core 2 Duo T5550 1833 2048 667
Core 2 Duo T5750 2000 2048 667
Core 2 Duo T5850 2133 2048 667

Core 2 Duo T5270 1400 2048 800
Core 2 Duo T5470 1600 2048 800
Core 2 Duo T7100 1800 2048 800
Core 2 Duo T7250 2000 2048 800

Core 2 Duo T7300 2000 4096 800
Core 2 Duo T7500 2200 4096 800
Core 2 Duo T7700 2400 4096 800
Core 2 Duo T7800 2600 4096 800

If you are looking to upgrade a machine with a GL960 chipset, there is a good chance that you can use any of these thirteen processors, though once again, compatibility is not guaranteed.
