I need some help from the guru's. Just installed a second E5472 on my asus board. With one processor, processor was crunching at 100% with. Few dips. Installed 2nd chip and seems ubuntu 10.10 is throttling like crazy. My other dual processor E5420 on a asus board runs 100% with very little dipping. Only difference between boards is one has 800 fsb, the other is 677 fsb. This has me baffled as to why one is barely throttling and the other is throttling real bad. Any suggestions?
