Another sure way is to take the CPU from the socket. On the side with the pins you have 3 printed lines, sSpec number is the first word of the middle line. Now that I am considering upgradding 2 machines, I seriously think about buying a pair of matching Xeon for each board as it has been suggested earlier. But at same time I had my hardware vendor try to sortout the problem for me with Intel (1 year old CPU, not manufactured any more).

Well I don't know anything at all about sSpec number, but these: Family: Xeon Manufacturer: Intel ID: 34 0F 00 00 FF FB EB BF Signature: Type 0, Family 15, Model 3, Stepping 4 Version: Intel(R) Xeon(TM) CPU 2.80GHz External Clock: 200 MHz Max Speed: 2800 MHz Current Speed: 2800 MHz should be enough for you to choose new CPU to pair with this one. Also look for L2 cache info (it is also in dmidecode output). Anyway your hardware partner should have data about server he delivered to you and which are you about to upgrade.. enough data to choose right CPU for you.. We have Fujitsu Siemens Primergy TX200 from Siemens and we just picked up the fone and called them that we want second CPU and RAM upgrade and that was all I had to do. -- martin hudec * 421 907 303 393 * [EMAIL PROTECTED] * http://www.aeternal.net "Nothing travels faster than the speed of light with the possible exception of bad news, which obeys its own special laws."
