Very important, read it before you kill your RAM

If I had a nickel for every thread I see about some problems with DFI nf4...

Mainly because its an enthusiast board....It is made to run like a beast out of the box it cannot be perfect. If everyone ran their DFI boards at stock :p:, I doubt you would see half as many problems.

been using the 414-3 since last night, so far so good and it appears to be just as stable as 331-3, though I haven't notice any difference or improvement, it would be nice if someone can try it and shed some light. :)

I can see what you're saying. I've also read that the bios the board ships with is complete garbage and you practically have to flash ASAP. :p:

the problem is not with the running of it, but the heat in the area...they have used higher tolerance mosfets in the area, but extended use would cause a large amt of heat to build up in the area...under stressful conditions, this may deteriote the performance of the board, but simply placing a fan blowing over the area should be more than enough to ensure continual operation.


Too many took that post wrong...IT IS OK TO RUN 24/7, AS LONG AS YOU TAKE THE PROPER PRECAUTIONS.

lucky me... I`ve done it(switching 1-2 jumper @ Vdimm >3.2V) a few times so far, and both the board and ram is still working... ^_^

Hey OPB can you ask oskar wu whent he dfi nf3 will come out?
And will i have this problem with that board 2?

maybe if everyone stops asking them about the NF3 s939 board they can finish this one!

DFI recommand cumstomer need to set to 3.3v AND clear CMOS before set the jp17 back to 1-2 default position.

OPB.. do you mean "need to set lower then 3.3v AND clear CMOS " before changing back to 1-2 position..

Sorry not trying to correct you just wana confirm it ..


Also is there any special things that need to be done when switching from the 1-2 to the 3-4 position ?

Thank you ..

ok, when jp17 at 1-2, the lowest default is 2.5v right?
3-4, the lowest default is 3.3v,
so when you done for playing the vdimm over 3.2v(whatever you set)
then you need to set it back to 3.3v or 3.4v then power off thenset back the jp17 to 1-2. so when you boot up, the vdimm will back to 2.5 or 2.6
That's about it:)

Ok .. I havent messed with that yet and didnt know that when set to 3-4 the lowest default is 3.3v.. I thought they were all there still but just worked off the 5v rail ..

So if im playing with over 3.3vdimm with the jumper on 3-4..lets say 3.6v..and I wana switch back to the 1-2..

Go to bios set vdimm to 3.3v or the lowest available setting.. then power down (clear cmos?)and move jumper to 1-2...

Also I read here in XS that to change from 1-2 to 3-4 the vcore setting needs to be set manually and NOT on auto.. so im assuming when changing from 1-2 to 3-4 clearing the cmos is not needed ?

Since clearing the cmos will make the vcore back on auto..


Sorry if im being dense..lol.. just want to get the correct way down so I dont kill anything.. ;)

Thanks again..

i'm running a 510-2 beta bios. Already killed 2 sets of redline :(

Its newer than the 414-2. But still killing the memory

In this tread there are people who killed there ram wile running the system and not even switching the jumper. In all cases it was @ +5v setting so i don't know whats worng withe these boards but i wil run 3.2 for now.

I think I'll just use my DDR booster........I don't feel like killing ANOTHER set of VX.

Nice. A board which supports 4V on Vdimm and people are still better off running boosters or maximizers (when they come out).

So true, This is only needed when you switch UTT to TCCD e.g.

When the Jumper is on the 5V, I first set the bios to 2.7V and THEN switch the jumper to 3.3V. Works all the time :)
