1. Please check your motherboard's PCB version. The PCB revision is printed on the board under the model name, such as ASUS P2B-LS REV.1.04. "ASUS P2B-LS" is the model name, "REV.1.04" is the PCB version. You can also refer to the following URL for "How to find motherboard product Revision Number?" http://www.asus.com.tw/inside/product_revno.htm 2. Please refer to the attached picture for the Coppermine CPU supported list and the max CPU support for your reference. Please note that P2B series only support 100MHz FSB, so please don't install 133MHZ FSB CPU on it. You may also refer to the following URL for more information: http://www.asus.com.tw/inside/Techref/Coppermine.htm . Some motherboards need Bar code for final identification. The Bar code is often sticked on the ISA slot or any other connectors, on the sticker it printed the number such as 010102-M6PB65-A02-00371. Please send it with the motherboard model name and PCB Revision to us to identify whether your board support Coppermine CPU.
