Ouch. Does it cost something as well or is it "just" the effort to go
through the datasheet request procedure? I think asking for the data
sheet just in case we'd use it later may save us the waiting time if we
ever need it.

Indeed. The wording is horrible. They should have written "Please note
that some non-standard high performance DIMMs may require voltages above
the standard 1.8V. Please set DIMM voltage to the values recommended by
the DIMM manufacturer."
http://www.kingston.com/hyperx/products/khx_ddr2.asp has a listing of
some of these non-standard DIMMs.
