msi 865PE neo2 pls (MS 6728 v2.0) voltmodding

[Jort]

Hey guys, I have a oc'ed cpu here.
pentium 4 prescott 2.8 ghz @ 3.69ghz (3.71ghz superpi stable)
totaly custum cooled system (Cpu, NB, Gfx)
first did a small oc then bought new ram(ocz pc 3700+ gold rev3)
then I could get to 3.5 aircooled, now problem sa far
then I got my custum wc installed and got to 3.7 ghz with aircooled NB.
but today i installed my NB block but no better oc.
so i am looking for a NB vmod, vcore not needed i think(goes to 1.6v, stock its 1.3875).
Vdimm goes to 3 V.


I searched on google, but no results, don't think any voltmod is done on this mobo. maybe just a guide where i could measure the NB voltage.

tnx on purpose

ps: if you want to take a look @ my wc (and case) topic is over here

You forgot to search the forum

Nice watercooling.

[Jort]

i searched but not on that type of mobo.
tnx dude.

about the watercooling, did some time building it but it was realy worth it

[Jort]

k read the entire thread.
this is the first vmod i do so, i need some more info about some stuff.
1st=> Vs,Vg,Vgs,Vds,Vd what is all that?
2nd=>i have time for this this weekend so.

tnx,

[Jort]

about the procc, i have a C0 stepping.

[Jort]

oke did some looking @ mobo.
there some things that don't match.
oke did some looking @ mobo.
there some things that don't match.

LM358 37M => LM358 39AH

HIP......=>HIP6601BCB L34FJ8

about the FET it saids=>NIKOS P06P03D Q3A44981

about the numbers that don't match =>is that just a serial or something?

just read some more in the vmod thread, it seams the 865 neo isn't a succes or do i see it wrong

[NoX]

Dude I have exactly the same mobo as yours. Same revision too.
The mod works fine.

[Jort]

oki doki then,
i'll buy a pot later this day(20K ohm)

srry just saw it on the mobo, did not pay attention to that

this is what i have to do he ?
20K @ max

[NoX]

Yeah, that's it!
Once you have done the mod , plz report the results in this thread.

[Jort]

oke if thats all :P

btw so you don't have to touch the pot @ all?

[confuzzedintel]

so this will also work for the MSI 865PE Neo 2 Platinum Edition?

By playing with the POT you can raise or lower the cpu voltage. For me, it didn't seem to produce any advantage so I set it back to max resistance.

[Jort]

uhm vcoremod is with this 20K or am i wrong.
or does it stabilize you vcore?
because you say =>

By playing with the POT you can raise or lower the cpu voltage

[Jort]

oke i did it, solderd a 20K resitor on the 2 pins.



very weird, i didn't make any advantage after the voltmod.
how mutch mhz more did you get with voldmodding your board?

[Jort]

oke pelt cooled my NB, its 5° @ 3.7 ghz(not stable)
the voltmod does nothing to my oc'ing.

NOX please answer ???

[NoX]

Maybe you have just reached the limit for the cpu. Anyway In my case the mod stabilized the vcore and it allowed me to reach the same overclock I had before but with a lower voltage. My max OC remained the same but the sytem stability improved because the cpu runs cooler wth less volts. I also noticed that now the vcore read by cpuz matches the bios value. Try to raise the vagp, I read that it's related to the NB voltage. I run mine at 1.7v.

[Jort]

i'll try increasing my Vagp.
