Intel D925XCV and 1.9 Volt DDR2 Ram

I've been looking but cannot find the answer to a DDR2 question regarding
the Intel D925XCV motherboard. In the documentation for the board, it claims
only 1.8 volt support for ddr2 ram. I was looking at some pc-5400 (667) ram
that runs at 1.9 volts. Will this 1.9 volt ram work in this mobo? Is the
voltage adjustable in the BIOS maintenance menu.
Thanks in advance.
