[Matthew Lucas]

well not sure where to post this, it's my first post but i acquired a IBM intellistation Z pro 6221 and i would like to upgrade the processor . it currently has dual single core Xeons at 2.8 GHZ and the motherboard is socket 604. I couldn't find much on it so any help would be greatly appreciated

That socket type was introduced back in 2002 and the last CPU that could utilize it was announced back in 2008.

Good luck. Here is a list:
