I have two PCs with DH67CL and i5-2500K. One has BIOS 0132 and the other 0146. I seem to remember that 0146 was the first one to include Ivy Bridge support, but maybe I'm wrong. 0146 is no longer available on intel.com. Intel deleted all information about the update, so I cannot determine if it was the first for Ivy Bridge.
I changed the Graphics Max Multiplier on both boards to 30. This is nothing radical, given that the default is 22. The curious thing is that the two WEI graphics indexes rose from 6.2 to 6.5 as expected on the 132 board, but did not rise on the 0146 board.
Questions.
- Can I go back in time with the 0146 board and install 0132?
- Does a later BIOS (maybe 0151) allow WEI to recognize a Sandy Bridge graphics overclock?
