I believe it's possible if you use a variable resistor but you won't get alot of variance that way, mainly the mod is more or less a straightfoward jolt of voltage. Luckily I have a few sets of BH5/CH5/HynixB that can use the boost.
I have a couple of dipswitch blocks I could use to turn it on or off with at least, also a few of those said resistors to try it with and see if and how far it can be adjusted. Scavenged these resistors from the now dead Ultra B that had all the mods applied to it and it was setup with these things all over it, clearly an all-out modded board. Too bad it didn't live long after I got it but it did work for a few at least.
Don't worry, I'll use the meter and check things as I go before I even try to apply it so no worries here.

If your variable resistors are the blue multiturn used in basic feedback voltmods they will not do to limit current by putting them inline with the dirty punk mod they are only .5 watt. Another thing having a resistor in the line is not a regulator the voltage will go up and down depending on the load the memory is putting on it when the system is idling the voltage will be higher than when the system is running say SPI and the mem is working hard. A regulator continually keeps the voltage constant under varying loads.
I would just run the punk mod with a switch to turn it on or off.
For everyone that doesnt know what the Dirty Punk Mod is its just running a wire under the board from one of the 3.3v lines on the back of the 20pin power socket over to the memory input so the memory gets 3.3v direct from the power supply.

Good info here - Running the mod with the switch then should work and I can set it up for on-off operation. However I also have variable resistors/regulators from things like a chem pump and electric forklifts I salvaged, the ones for the lifts actually control the speed of the lift depending on how much control voltage is sensed, that telling the motor controller how much voltage to give the drive motor ='ing how fast it should go.
I'm just experimenting here, these could do it or as you said not, depends on what it really is and how it applies to the setup. If it's a regulator type then it should work BUT I'd still have to check by how much it controls the voltage from source to end before actually trying it.
If it has no effect then I'll know not to use it but if it does affect voltage then it could work - Not that it actually will until proven and I do have a few things to test with if I have to. I will also look into soldering in a cap or two inline to see how that works.
If it does work I will definitely chime in about that and say how it's setup and such for you guys to use if you want.

Thanks all, learning stuff here, have a couple buck controllers coming.

dirty punk mod, (double dutch to me), sounds like a bloody good name for a punk music band to me

Dirty Punk was a user on a forum who came up with the idea of running a wire under the board connecting the 3.3v wire from the power supply to the output of the memory regulator feeding the memory 3.3v direct from the power supply. Hence the name dirty punk mod. You have seen the power supply that I have got with a trimmer for the 3.3v rail run the 3.3v rail at 3.6v and you have got 3.6v memory voltage with his mod.

A picture is worth a thousand words here is a pic of the dirty punk mod as you can see it is just a wire from the 3.3v pin of the motherboard plug to the memory. Scotty do you know anything about this VDD booster mod?

Yes. It's never been proven by anybody to do anything. I've tried it, makes no difference in anything.

Same thing as a FJQ4C, just newer manufacturing date. Should clock well. Interested in seeing it go. Wanna see my box of 462's?

Right it just looks like an extra power link but if there is sufficient copper in the board for the load it wouldnt do anything.

Question if you are filling more than one memory slot does each slot need it's own wire?

Thanks for the 12v idea Pete. That's the way to go. Buck set at 3.6v delivers a solid 3.62v to the dimms. Awesome.

I will get the virgin board I have got here out in the next day or 2 I am just going to try the dirty punk with a 3.6v rail.

Here is my board as you can see its virtually the same as Scotty's with an A1 Northbridge. I know it posts but I dont know the bus speed its capable of will find that out in running. I have gone with the Dirty Punk Mod a straight connection to the 3.3v rail from the power supply to the mems with no adjustments I have also added another 1000uf of capacitance. I have got a power supply with the 3.3v rail modified with a trimmer so I will run the 3.3v rail at just over 3.6v supplying the mems with 3.6v I have also gone with a hard VDD mod I have a dislike of pencil mods for anyone thats wondering the small resistor that is next to the chip where I have soldered the wire to is the one Scotty has shaded with a pencil it basically does the same thing I have also put a new Enzotech copper NB cooler on it. I have yet to glue heatsinks on the Mosfets.

Went ahead and ordered up a buck controller for my use.
I do have an idea about how I'll set it up and the particulars about it, should work great once done BUT the final results will be the true judge of that.

Looks good Pete. My board does about 270 max. Been doing around 240 @ 2-2-2 Not really happy with that.

I started testing mine this arvo it will boot at 248x11 2-2-2 but not stable I couldnt get through SPI at 245 its going through Ok now at 242. Not happy either I will try another CPU or 2 in it yet also will make sure VTT is tracking properly I know on my other board it didnt and the VTT mod improved it.

Probrably won't but have to ask anyway - Don't suppose the Dirty Punk mod in some form could also work with an AN7?

So what is the difference between NF7, NF7-S, NF7-S v2.0? Any one better than the other?
|

Post by Macsbeach98 on Dec 7, 2017 9:03:45 GMT -5
S stands for Sata. You want a version 2 of either NF7 or NF7-S

Post by mrpaco on Dec 7, 2017 9:30:56 GMT -5
Cool, I already have the NF7-S v2.0

Macs what value is this part to order? variable resistors are the blue multiturn on your mb pic

Great link ... that is seriously cheap yep, takes 3-4 weeks to get here tho, no biggie, i dunno what size he uses tho, diff resistances for diff applications i know that, too bloody techo for me, i bought him a box of em last year coz hes done a few cards and boards for me, and pete sets them like a tap, anti clockwise is for more , clockwise is less, like a tap, easy to remember
