i'm with reggie, no need to put the voltage up like that. wait until you're using the DFI as they are brilliant for overclocking. you will always want to increase the voltage by the smallest amount possible when you find it is necessary to do so. as for your memory, if i were you i would use a "divider". look around in the BIOS. it will be a ratio for the memory:FSB frequencies. set it to smallest one possible. i.e. the one that is furthest from 1:1. this is just so that you can find out how far you can overclock your cpu without any problems from the memory.
edit: with the DFI you won't have to worry about the LDT ratio anymore. at least not until you really know what you're doing
as the "auto" setting is good enough unless you are breaking records.
