Not sure we can take this change for that reason. I'd also like to understand how much of a difference these specific tunes actually give. I know the Intel people have been trying to focus on a smaller number of tunes that work well on the majority of platforms rather than micro optimising the tunes. Are there some benchmark numbers or other analysis which shows these tunes as being more effective? Cheers, Richard
