I reach FSB limit for this mobo is 140mhz any more have no effect simple after reboot in bios setup I will see for example 145 but when I boot windows cpu-z will detect only 140 (exactly 139,92)
140 FSB, of course, is fully stable.
I would understand if the higher FSB was not stable but it clearly looks like a lock.
And about Ram Voltages I want push a bit more but 1.65V ( mobo limit) it to low for more OC
