The idea of combining FB-dimm with ordinary DDR2 is meaningless imho. Firstly, completely different preassignment and hardware component. For all frequency and speed characteristics, the FB-dimm will lose, no examples are needed here. This is the same as combining FPM and EDO based on the conclusion, that they are structurally the same and the number of contacts is identical.
I suggest that energy be directed in a different direction. Somehow, in search of one user, I stumbled upon a situation when I found more than a hundred registered overclockers from my own micro-country, with zero points and no results. It seems to me that there will be hundreds of thousands of such users who have been hanging for many years, and this is the place in the tables, and a waste of time in calculating their zero results. I propose to remove all those who registered more than a year ago and did not give a single result, I think this will benefit the HWBOT database.
