[Bug 429036] Re: core i7 i5 (Lynnfield) turbo boost not working

Sat Mar 20 16:40:02 UTC 2010

CPU: core i5 750

MB: intel DP55WB
BIOS: WBIBX10J.86A.0251.2010.0302.2003 (03/02/2010)

OS: ubuntu 9.10 (karmic)
Kernel: 2.6.31-20-generic

gnome cpu scaling frequency applet reports 1.20GHz to 2.67GHz

i7z reports multiplier 9x to 23.96x

can i assume turbo boost is working for even a standard karmic system on
2.6.31?

Bacchus said hardinfo CPU N-Queens is single threaded and his result is
0.88s, but what i get is all 4 cores max out 100% @ 21x with a result of
8.65s! any idea what's up?
