If it isn't broken, don't fix it. the problem is: how do you know it is stable? Just might be lucky that fixed function was not hit by you so far. But will that be true tomorrow? Next week? With the next gcc version? Microcode updates are there for a reason. There are ZILCH reasons to turn it off in the bios. 'Oh, there are a lots of fine 4cores marketed as 3cores. I want that' is not a reason not to turn it on. It is a reason to buy a mobo who can unlock those cores without turning off microcode updates. Call me old fashioned, but I prefer computers as deterministic machines - and not very expensive random number generators (which is also the main reason why I don't overclock. 5% faster for 1% better chance of errors? 5% I will never ever able to 'feel'? No thank you).
