Disappointing that Asus has not provided the BIOS options to lock in a specific RTL value for each channel manually. Instead they continue with this 'let the board decide' scenario which causes a lack of repeatability of results, and takes control away from the user. If I spend this much on a board, I want to be able to set things to what I choose. This is the same behaviour the Rampage II Extreme has, and I have raised this exact issue with the Asus rep on this site and nothing has been done to correct it. Interesting to see the legit reviews reviewer of the Rampage III Extreme raise the same point in a negative light.
