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, 965, and 45 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 processor.

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.

Note on the GL960

08/12/07

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

As of this update, at least one person has reported a successful to an 800MHz FSB Socket P Core 2 Duo with the new Penryn core, specifically a T8300. Hence, if you are looking to upgrade a machine with a GL960chipset, there is a decent chance that you can use ANY 800MHz FSB Socket P processor, but once again, compatibility is not guaranteed.

Note on Socket 479 and Socket P

08/09/06

Socket 479 and Socket P have both supported two generations of Intel mobile processors, with the later generation having a higher front side bus. In both cases, the later generation of processor will not work with the previous generation of chipset: almost always, a 533MHz FSB Pentium M will not work with a 400MHz FSB chipset and a 1066MHz Core 2 Duo will not work with an 800MHz FSB chipset. 400MHz FSB Pentium M processors work in 533MHz FSB chipsets, but there is no confirmation that 533MHz to 800MHz FSB Core 2 Duo processors will work in 1066MHz chipsets.

Note on Core 2 Extreme and Core 2 Quad

08/12/25

While nominally Socket P processors, Core 2 Quads and Core 2 Extremes have a significantly higher TDP than the typical Core 2 Duo. These processors usually require a special motherboard and/or BIOS to function properly. Subsequently, even with the correct socket and chipset, a given notebook may not work properly with the following six processors:

Core 2 Quad Q9100 2266 2/6144 1066

Core 2 Extreme X7800 2600 4096 800
Core 2 Extreme X7900 2800 4096 800

Core 2 Extreme X9000 2800 6144 800

Core 2 Extreme X9100 3066 6144 1066

Core 2 Extreme QX9300 2533 2/6144 1066

It is very useful to have this info in one place.

Can I suggest that you also add the L and U (low and ultra-low voltage) CPUs although, as far as I know, they are all soldered (BGA) and not socketed.

Nice guide! Nice to see my good old PM 725 on there

[vshade]

You could add the amount of cache on each processor....

[powerpack]

Nice work!

[moon angel]

Nice. You should add something about chipset compatability, e.g. Banias Pentium-M is generally 855 while Dothan is generally 915 and 943 doesn't usually support dual core except in some cases etc.

[kclives]

Thanks .

In order for a particular processor to be physically compatible with a certain laptop, the processor simply needs to the fit the laptop socket. In order for the laptop to function properly, the laptop chipset and FSB and the system BIOS need to support the particular processor.

Does this mean putting a 1066 MHz FSB Montevina (Socket P) chip in a laptop that originally had a 667 MHz or 800 MHz Santa Rosa chip will not work? Or will it just be limited to the 667/800 MHz FSB?

Noted, noted and noted. Will try to update when I've got the time. Thanks for the input.

By all means it should not work, though there are rare cases where a workaround may be possible.

Excellent work, Commander.
