Working Msi P35 Neo2-fr / Platinum Vdroop Mod

[Kobalt]

I just measured from the coils around the CPU socket (IIRC)

Do you remember if it was the coil by the mosfet heatsink (which would be nearly impossible to measure without removing the heatsink) or the one by the molex connector and northbridge?

I measured the one by the molex connector and i got 1.412V (set to 1.4125V in bios). But then I measure absolutely 0 vdroop (even to the thousandths place). Surely this can't be correct ?

Then that is the one I measured from, because I got very little vDroop as well. Something like .005 vDroop. And that was the only thing I found that measured anything that could have been considered vCore.

Ahhhh okay thanks! I never thought of measuring the inductors. I just poked around at the mosfets and found some that read 6.4, 5, 12, 1.6, and 2.1 (vdimm). The ones that give vcore are probably covered by the heatsink.

hey andi where did you get this info, and how has it been treating you. Any more info since the last post? I would like to vdroop mod my neo2 also.

So far so good, running at 3.6Ghz with a Q6600 G0 for six months or so. My board is Rev 1.1, vDroop droped from 0.1v max to 0.03v max.

It worked fine for me, I gained stability with less volts through BIOS, from 1.525v to 1.4875v right now. ~1.46v Idle 1.43v full load stable. Without the mod with 1.525v BIOS I get ~1.41v full load.

so is ther any hardmod?? I would love a hardmod but will use a pencilmod

[SiGfever]

Just did the pencil mod to my v1.2 board. Running Prime95 on my e8500 @3.9 to test. Will go to 4.0 if Prime95 stable for one hour.
Thanks for this mod.

I cannot find the chip that this mod is under, can anyone give me a location?

[oli_ramsay]

I believe it's just above the left RAM slot.

[philbrown23]

k found it penciled it and brought it to 1.458kohms and no vdroop at all anymore

[AndrewZorn]

I went to ~1580ohms (just happened to land on the same number as OP) and vdroop went from ~.05v to ~.025v. Should I mess with it more, is NONE realistic? It was really hard to me, I've never done this before. When I finally located the resistor I thought, NO WAY... that is SO MUCH SMALLER than I expected...

[philbrown23]

mine no longer droops at just unde4 100 ohms less than yours so hell yeah none is realistic just dont pencil to far or it wont boot he he went a tad pencil happy, I wish this was a hard mod or a vcore mod I I wouldnt have to enter the bios at all, infact I would love that on every board I own, bios less overclocking

[AndrewZorn]

Well there's talk about how vdroop is kind of a safety measure and surely any electronic engineer could completely eliminate the phenomenon.

By the way, I was never close to 3.9ghz before, but I think I might be able to make it happen now... I think at 70mhz increase is going to be pretty easy though.

EDIT and I really hate to go off-topic, but what is a good/safe max FSB, NB, and SB voltage? I'm afriad to go over 1.325 on FSB because I don't know what it does, I'm afraid to go over 1.45 on NB because I know what it can do, and I'm afriad to go over 1.6 on SB because I don't know why to do it.

[philbrown23]

ive had nb maxed out on this board, same with fsb volts so with proper cooling they are safe.

[highspeed]

Hi there, really noob question, but what you mean exactly with this pencil mod. You take a pencil and "write" over that resistor or what You need any special type of pen for that?

thx

[philbrown23]

yep just scribble the resistor a bit and measure resistance but dont go to far, if you do just erase and start over.

1.45 NB voltage is nothing.
I'benched many hours with 1.65 vNB.
P35 isn't that much different then P965. I have benched a few times with a P965 @ 2.4 - 2.55v and it only crippled the P965 a bit, but never died.
