Hi
I am speccing a new machine for some heavy math number crunching, looking at using i7 860 in an asus P7P55D-E Premium board.
1) The memory QVL published by Asus does not agree with the QVL in the manual, will both sets be applicable ?
2) Finding affordable memory from the QVL is a nightmare, What risk is incurred departing from the QVL ?
3) Are any warranties dependent upon keeping within the QVL's
4) I understand that using memory with a transfer rate above 1333 GT/s, the processor will downgrade the memory transfer rate to 1333 for a proc speed of 2.66 GHz, and to 1066, for some slower proc speeds. What about higher proc speeds ? Is the process scalable.
5) How does 4) work with XMP
6) Which Intel specification states that for 1600 GT/s memory, only one DIMM per channel can be used, what about memroy modules with higher transfer rates.
I would appreciate any advice, there is a great expense at stake and I dont want to make any mistakes.
Many Thanks
