This page is designed to help interpret the markings on a mobile Intel® Celeron® processor, and to explain some of the tools available for determining the stepping, voltage, and features of a particular Mobile Intel Celeron processor. The primary tools that will help identify a mobile Intel Celeron processor are the Intel® Processor Frequency ID Utility and the Specification Update.
The Intel Processor Frequency ID Utility was developed by Intel Corporation to enable consumers with the ability to identify and in some circumstances determine if their Intel processor is operating at the rated frequency intended by Intel Corporation. Beginning with the Pentium® III processor, the Intel Processor Frequency ID Utility has the capability to provide actual and intended frequency or speed.
If you need information about the voltage, thermal specifications, the processor packaging, or other information about a particular mobile Intel Celeron processor, you'll need to view the part numbers on your processor and compare that with the Specification Update or the Quick Reference Guide.
The Specification Update is a document that has more complete information, but the Quick Reference Guide is a web-based tool that may be a bit easier to use.
The Product Specifications and Comparisons tool was designed as a reference to help you look up technical spec information on your Intel® processor. To find the information that you are looking for, you will need to know your processor's sSpec number.

Micro-PGA2 and BGA2 package types
The mobile processor's Micro-PGA2 and BGA2 packages have laser etched markings that indicate the processor's core speed, L2 cache size, S-spec number, serialization code, and country of origin. The markings are located on top of the chip.

Mobile module markings (MMC-1 and MMC-2)
The Product Tracking Code (PTC) determines the Intel assembly level of the module. The PTC is on the secondary side of the module and provides the following information:
The PTC will consist of 13 characters as identified in the above example and can be broken down as follows: AABCCCDDEEEFF
||Processor Module = PM|
||Pentium® II processor (MMC-1)=D|
Pentium® II processor (MMC-2)=E
Pentium II processor with on-die cache (MMC-1)=F
Pentium II processor with on-die cache (MMC-2)=G
Intel® Celeron® Processor Mobile Module (MMC-1)=H
Intel Celeron Processor Mobile Module (MMC-2)=I
Intel Pentium III Processor Mobile Module or Intel Celeron Processor Mobile Module (MMC2) - .18µ=L
Pentium III Processor Mobile Module with Intel® SpeedStep Technology (MMC-2)=M
Intel Celeron Processor (.18µ) Mobile Module (MMC-2)=N
||Speed Identity = 266, 300, 333, 366, 400, 433, 450, 466, 500, 550, 600, 650, 700, 750, 800, 850, 900 and 000 (1 GHz)|
||Cache Size = 01 (128 KB) - Intel Celeron processor|
Cache Size=02 (256 KB) - Pentium II or Pentium III processor
||Notifiable Design Revision (Start at 001)|
||Notifiable Processor Revision (Start at AA)|
H=Intel Celeron processor Mobile Module (MMC-1)
01=128 KB Cache
