Note:
With CPU speed changing rapidly, there might be fastest CPU on the market by
the time you received this installation guide. This table is kindly for your references
only.
Warning:
Intel
®
875P
(Canterwood) chipset supports
maximum 800/533MHz
(200/133MHz*4) system bus and
66MHz AGP clock; higher clock
setting may cause serious system
damage.
Note:
Since the latest processor,
Northwood, would detect the clock
ratio automatically, you may not be
able to adjust the clock ratio in
BIOS manually.
