''Because Intel® Turbo Boost Technology is a processor technology, first make sure you have an Intel® Turbo Boost Technology supported processor. Desktop board vendors normally enable Intel® Turbo Boost Technology by default. You can typically enable or disable through a switch in the desktop board BIOS. See your motherboard documentation or vendor website for more information''

I use non k cpu's and works fine - I yet to see a motherboard [intel] that did not support it -- even using a non k cpu I still prefer to get a ''Z'' board for the rest of its options and features [opinion] may go with a k cpu and covered may go sli and covered the ''lesser '' board series [H-B] may find yourself short if doing a certain up grading or not covered ?
