I have an Abit SA6 i815 motherboard which is rated up to 1GHz. I currently have a P3 866MHz in it. Is this maximum rating or just another manufacturers theoretical maximum. I.e can I buy a P3 1.2 or 1.4 GHz CPU and use it in this board???????? FYI: The 1.2 has 256Kb cache and the 1.4 has 512Kb cache. SO, CAN I UPGRADE WITHOUT HAVING TO BUY A NEW BOARD AND RAM OR NOT? PLEASE HELP!
