[Searching] NF7(-s) v2.0 Vdimm to 3,3V Rail mod

I looked hundered times on the board, there is no burned point etc, when problem happened, there was no smell.... I don't know what will I do, I'm only smoking now....

Here some picts...
I know my bedroom is not tidy :D

Could be the bios is corrupt, or the vtt=vref mod killed it.

vtt = vref is the worst mod ever, i have always said that....do the cut trace or dont bother.

Can somebody please post a FINAL results as to what is best to get ram voltage to 3.3v please, im getting way confused with everyones different opinion! :confused: thanks per advance! :D

If you wanna do it right, then do the vdimm mod as it is supposed to be done - here. You'll also need a modded PSU.

If Im using my 600w OCz Power Stream with ajustable rails, i just use a multimeter and up the 3.3v rail to 3.4v and do the mod as stated above correct? thanks for your help!

So the dirty mod using (1) wire from the the 3.3 line does not work? (with an adjustable power supply)

Its just i dont want to have to remove parts off the board and add resistors and stuff - dirty punk mod looks easy enough - but can i get a verification it works>? Can you use the OCz DDR Booster with this dirty punk mod? not that you would - just asking if you can boot it up with one once the mod is installed to the back of the mounted motherboard. Maybe if u boot up with th rheostat turned down??

- ANother question, when doing a mod like this using the straight 3.3 rail - does it ADD to the voltage the bios normally produces?> like if you have 2.7v set does it just go to 3.3 or add together? How can you boot up with less than 3.0 AFTER doing the dirty pumk mod without killing mod? thanks!!

yup, u can use ddr booster together with this mod. but becareful, once u increase the vdimm, ur 3.3v rail will increased too.

once u did the mod, u cant set the vdimm in BIOS, u jz manage to do so via adjust the 3.3v rail. since u r using adjustable psu, that's not a problem for u.

I still dont understand - they add together? where would i change the overall volatage seting at - the bios will still show up to 2.9 (i believe) and once the mod is done it will be 3.3, how do i lower that after the mod? can you use the ddr booster for that....im trying not to use ddr booster because it takes away dual channel...i want to get to 3.3v but not at first, ive never pushed these sticks that hard and i want to do it slow...ya know? use the ddr booster to get to 3.3 on each stick, then do the mod, set 3.3 rail on psu to 3.4, boot computer, should be 3.3 vdimm right? :confused:

btw - i meant use the ddr booster to 3.3 to (test) the modules - then take it away and then proceed doing the mod/psu changes....

With the dirty punk method, the Vdimm will be exactly what the 3.3v line is set at and won't be effected at all by what the Vdimm is set to in BIOS.
I wouldn't suggest using the DDR booster with the dirty punk mod because once you set the booster to a voltage higher than your 3.3v line, you will be drawing a lot of current through the boosters MOSFETs (probably 30+ amps at full load), which the booster probably won't like ;)

Ok - I just recieved the DDR Booster...finally :mad: - newayz ...im havina tough time with this sorry :eek: Im going to test run the 3.3v using the ddr booster to verify that these bh5's will hold that voltage. After tests are ok i will perform the dirty punk mod on the board > question: I just hook up 1 wire right??? or should i do the other mod that is show in the pics??? At this point i would remove the booster....

The simplest way to do the mod is to do the direct link between the 3.3v line pin on the ATX connector and pin 7 on the Dimm slot (as shown here - ignore the Vdd booster mod - you don't need to do it)
The other mod which uses the capacitor connection instead of the connection on the Dimm slot, and will probably provide a more stable voltage.

Can anyone verify that the capacitor way is beter?> or beter yet, can anyone say they knew anyone that screwed their ram up by using the straight through dirty punk way? thanks for your help persivore

im fairly tempted to do this mod, its so much simpler in comparison to the standard Vdim resistor mod, im just thinking though, wouldnt it be possible to add a resistor in line with the wire between the 3.3 atx ping and ddr pin in order vary voltages to the ddr socket, ie. increase resistance slightly and drop the ddr voltage to like 3.1 or whatever?

You can't use resistors to drop the voltage. The Vdimm supply needs too much current (15A+ with 2*512 sticks of RAM) which will burn a resistor very quickly, and resistors won't provide any regulation for the Vdimm, so it will fluctuate a lot.
If you want to get a voltage lower than your 3.3v line (unless you have a powerstream!), you need to do the standard mod with the variable resistor. IMO, its not any more difficult, and will probably provide a more stable Vdimm.

Well, I know there is all this good stuff about the Dirty Punk method, but I did the standard resistor mod with the vtt mod, and I get up to 3.2V stable, and I can still control it in the BIOS. I have it set to be about .3V higher than whatever it is in the BIOS. So if I drop down to 2.6V, i get 2.9V. 2.9V, I get 3.2V. I think this is a pretty good method. I don't know, guess I just have hesistation on bringing in the 3.3V line without it going though some filter caps and stuff. Or does this mod's power still go through the same circuits?

Either way, i suppose you'll get more voltage :P

did the atx to pin7 mod over the weekend, with a standard switch on the cable as well so it can be turned on and off without a problem...

so i got a choice now, 2.6-3.0 through the bios or flick the switch and have 3.3 to the ram :)

seemed to work without a problem but it hasnt fixed my inital ram problem though

nice vmod!
monna get that when i get my bios fixed =)
