hi, im curious about the new dfi nf4 boards, like i have heard ist can go over
4v to the rams, and if so the cpu (mem controler is inside) can be damaged ?
or its like a "booster onboard" :D

the cpu cant be dammaged by vdimm voltage. This used to not be the case (ppl were killing their a64 chips with memory voltage) but now amd fixed their chips and they are not bothered by high vdimms.

i take my neo2 and 3200 winchester and work with my booster at 3.5v on vx memory and its work jest great (+- but its not the issue).

then i put out the booster and do vdimm mod at 3.5v, the system cant be boot at dual mode (the purple dimms on my neo didnt work) then i take out the vmode and check with my fx - work at dual.
i send the winchester for the amd distributor and gat a new 1 - the mem controler on the old winchester are dammaged .

the 4v vdimm on the dfi can work without threaten the cpu ?
like the ocz booster do .

you can make the mobo draw voltage from the 5v line if you need more than 3.3volts, or at least thats what i gather. they talk about it some in this thread http://www.xtremesystems.org/forums/showthread.php?t=50421

Actually, there's no difference if your vdimm is generated by the board, or by the ddr booster. It's still the same voltage that passes through the memory controller in your CPU. No voltage above spec is "safe" for your components.
It'll still be luck of the draw and dependant on a lot of factors, if your parts will stand the high voltage.

ok...
i dont know why but i waz thinking thet the ocz booster get the voltage directly to the dimms while vomd or onboard voltage go through the cpu memory controler.
