have a look in the manual, you can find it on the product page, answers at least the voltage question. I'm running 4x2 GB GEIL DDR3-1600 9-9-9-9-24 on it, which makes no problems.
This is a new motherboard and I guess once more memory manufacturers have validated their memory for this board then there will be a wider range of compatible memory and also we will be able to known what latency this board will support.
It is a bit more diffucult to make an exact specifications about these memory details on these boards since the memory controller is on the processor rather on the motherboard itself.
This board will support memory that have a voltage of less that 1.6V.
Hep this will be useful to you.
Kingston HyperX 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600. CAS latency 8. 1.65V.
So far working fine.
