Lanparty P35 Dark, pictures, voltage measurements and vdroop mod

[s e t h]

[Garrett]

Nice find, excellent quality pictures too... unfortunately I won't be able to measure the cpu voltage due to my EK Supreme block... the holddown plate blocks access to that point

I've had the board for a few weeks now, haven't had anything strange with it so far

Also, this is the first time I see the possibility to eliminate vdroop by bridging a resistor
Then you create... v-up? lol...

[ztop]

how i can do the pencil v-drop mod?

[Supertim0r]

awesome !!!

If I understand correctly, it will overvolt ? idle ex : 1.4v and load like 1.42-1.43v ?

Thanks a lot for the vdroop mod

[TSFroggy]

How similar are this board and the Blood Iron? I've heard that they are about the same, except for some board layout exceptions. I ask because I've been looking for a vDROOP mod for a while for the Blood Iron...

[Peter949]

Can someone confirm this working?

Im also looking for this mod !!!

i bridged the resistor to 0- ohms with > adhesive conductive paint <

same resistor...just blow any loose carbon away carefully. you don't want any getting between two other pieces of mettle anywhere on the board

awesome !!!

yes...now it overvolts at stock...and then overvolts further when loaded...minumum load voltage available after the vdroop mod becomes 1.436v ...without the mod minumum load voltage is 1.312v.

[ztop]

i don't understand.. if i made de pencil v-drop mod and i set from bios 1,3v, in idle wich is the real v-core? and in full load?

[Lestat]

i dare you to use conductive ink on that mobo for droop mod.

go ahead see wtf happens.

and you realise what your doing to the other parts by giving zero resistance right ?

Me too!

Excellent pics, BTW.

[Greed4Speed]

Very sexy board, pitty I can't buy one of those in my country (UK).

[CERO]

u can buy them in germany ( stock overflood) and get them shipped to the UK for fairly cheap. I know many UK`rs ordering from shop like www.trend4pc.de and hpm-computer.de, both shops sell them for pretty cheap.

[RGone]

Vdroop is a drop/droop/sag at load not an increase over the set Vcore as this seems to give. A real Vdroop mod as I have seen them does not increase Vcore from what is set in bios but only stays at the set voltage by disabling the droop circuit. It would instead seem you have hacked the voltage offset and not the Vdroop. I would actually wish to have my Vcore set to 1.5 knowing droop would lessen it or a mod to disable Vdroop and me still have 1.5volts but I certainly would not want a mod that increased my set Vcore by some amount that could dink my cpu with an overvoltage beyond what was expected and knowing the tolerances of boards, could wind-up being a far greater voltage than expected.

[s e t h]

ah well i'm just repeating what a trusted DFI engineer told me after testing it myself...the fact that it differs from what's expected is possiblly due to this particular design being new to DFI

this is only really needed by LN2 heads anyway when looking for more vcore than the board delivers stock....and useless to air/water heads.

kind of suprised by the deleted thread at the club.....but then again not really

What mem do you have and what was the first vDIMM you booted with? (Garrett)

Deleted? NO. Moved yes. There was a section for Modded and Out of Warranty that might have proven to be a location much more suitable for such board modding since it certainly will void the warranty on the board. Or here at Xs which is supposedly for the extreme user able to shoulder the responsibility of board modding onto his own shoulders and not flinch if the modding kills off his stuff.

See I know how you push your parts and pieces and have seen some of your scores. What that does not transfer over onto is JSP and his understanding. It is mostly our problem at the Club to get the newer user up and going and not point him in a direction that if caught will certainly void his warranty. Two entirely different aspects of the computer game. Two different venues likely for such exploitation of the boards. Luck to you in your runs with LN2. RGone...

i need a 45nm chip before i bench again anyway.
how did it go with you building yourself a block?

anyway i think that thread got moved into the twilight zone somewhere because i can't find it.
but no sweat...all it has was a few pretty pictures really
if your mods can find it and they feel like saving anything for any thread thats fine...

[RGone]

Got down to the point of working out a couple of early pots and got side-tracked into phase and helping a bud with ideas on a water chiller. Just too many things happening at once that grab off attention nowdays it seems. RGone...

On this controller, VDROOP is controlled by leg #15 being connected to leg #14 using a tuned RC network. If VDROOP is not a desired characteristic leg #15 is to remain disconnected. Because of this requirement the proper way of eliminating VDROOP would be the lifting of leg #15 from the board. The unexpected rise in VCORE resulting from this mod is most likely due to shorting the resistor of the offset circuit. Anyone doing this mod needs to be aware of the possibility of blown MOSFETs. With only two FETs per phase, they are going to be hard pressed to cope with the on-load transient spikes that will occur when the processor is pushed hard. This will be especially true when using a quad-core CPU.

very well said Praz.

yet another reason why ghetto mods are dangerous. and more dangerous when done by someone who doesnt fully understand the reprocussions.

conductive pen or ink should NEVER be used as a form of resistance in ghetto mods.
conductive pens are used to create a trace, or a path for current to flow.
thats why they use it on the Core 2 Duo chips for the 1333 mod.

to use it in a mod where resistance is required is utter trash and all you're going to do is kill your motherboard or the hardware attached to it.

now he may have offered it as a suggested tool be cause he is asking for 0ohm resistance which is a dangerous game to be playing on such voltage sensative hardware. (and i dont mean the cpu necessarily, i mean all the other hardware)

Is the board layed out on a gravel road in the pics ?!?!

LOL!

That's what it looks like.

I know this has been said, but I will say it again: with no resistance on the voltages you are putting most components (CPU included) under some high stress. I wouldn't call this mod useful for air or water set-ups--but it would certainly be so for LN2.

Why put a motherboard on gravel ?
