Lanparty P35 Dark, pictures, voltage measurements and vdroop mod
-
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 :D
I've had the board for a few weeks now, haven't had anything strange with it so far :up:
Also, this is the first time I see the possibility to eliminate vdroop by bridging a resistor :eek:
Then you create... v-up? lol...
:up:
-
how i can do the pencil v-drop mod?
-
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 :up:
-
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...
-
Can someone confirm this working?

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 :D

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.
-
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?
-
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.

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

Vdroop??
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. :confused:
-
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

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...
-
Got down...
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 ?!?!

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 ?

look at the picture of the ports...there is a foam mat under the board.
its a concrete slab and used as a background for visual effect

Praz, could you please indicate which is that leg #15 in that picture? http://www.flytek.effectivehosting.c...ark/vdroop.jpg
You could use descriptive words like "3th leg from the left at the bottom of the chip" as well :D
-
you're right... it says pin 13-24 on bottom row, so 15 would be the 3rd from the left... lifting smd leg :| does not seem easy to me?

Actually, I just blindly guessed lol :) Got that board only yesterday, haven't had time to check it out yet.
-
both pin14 and 15 connect with 0 resistance to the now 0-ohm bridged resistor

Somebody tell me please. Where is Vcore Mod For LN2?
-
hi all
Not need Vcore mod in this MOBO because his max in BIOS is enough same on Ln2 cooling (+2v...)
We need only Vdroop mod
-
So basically this mod is not eliminating vdroop but rather is overvolting. So those of us on air that are having issues of setting the vcore to 1.46 and then having it drop to 1.39 under load will not benefit from this mod and should think of getting rid of this board and opting for the UT which does indeed have vdroop control in the bios?

You've hit the nail on the head ElAguila. Unless you are contemplating LN2 runs, the pencil mod will not help you. All the original poster found was a way to over volt the board. In the manner it was done, the long term consequences on the balance of the components are unknown. In your case, I would not do the mod. Either live with Intel's V-droop spec or opt for board that is built to override Intel's V-droop spec through the BIOS.
-
Thanks for the clarification.

1.46 and it droops to 1.39 man you got a poor board then.
mine, and MANY other people i have seen only get 0.02v
i set +.300mv and get 1.42 in the bios (1.44v in windows) and it only droops 0.02v
-
I know this sounds crazy but after I moved my ram from the orange slots to the yellow slots my vdroop went down and I was able to settle on the oc that I have in my sig on my cpu, video, and ram. Not too bad for this cpu and my 620w psu.
-
i tried yellow slots,no difference here...
same drop as in orange.
-
today i made the droop mod with conductive ink.
before i had 0.07v drop @ load
now overvolts 0.01v @ load
after the mod pwms are ~5c hotter
-
Can somebody get me a zoomed out pic of where the vdroop mod is supposed to be? Thanks

i would think its best have the board free and clear of a case and psu wires too.
the very last thing you want is to mistakenly join the wrong points or get carbon dust flying who knows where.
inspect your mod as clearly as possible, with a magnifying glass if you have one, to make sure you have done it right.
also take careful note of the vcore results i posted so you know what to expect for actual load vcore after you complete the mod.
mine has been running with the mod since i posted this thread...it's my 24/7 rig and the cpu is a QX6850.
edit:...and yes it would be wise to clear cmos...or at least drop the cpu to around 3ghz and set stock vcore to start with

Thank you again :up:
Can I use a #2 pencil? How many times do you stroke it with the pencil, and how much pressure to apply?
-
well pencil modding is a rather inaccurate science at the very best of times.
ideally you want to measure the resistance of that component with a quality multimeter prior to pencilling it and then again after pencilling so you can see the resistance drop as the carbon conducts around rather than through the component.
usually i find one has to stroke more than i would expect before any result is seen.
please make sure you blow away any loose carbon that will fall around the area as you stroke.
in this case where i'm pretty certain you can use as much pencil as you like its also possible to pencil the sides of the component in question to reduce the resistance further.
for everyones benefit it would be very nice if you would take a few vcore and vdroop measurements, with smartguardian if you have no multimeter, so that when you're done (and repeated your measurements) we have some idea of what you achieved with the pencil method.
-
In the picture is says I only have to pencil the side of the resistor. I don't have to pencil anything else?
-
you can safely pencil the top and both the sides too...and you can use lots of pressure.
my diagram indicating the side is really just so the component can still be seen after marking it.
with conductive ink one can paint just the side of course as the resistance will drop to 0 no matter where its done.
with pencils it will take quite a bit of carbon to drop the resistance meaningfully and i think you'll need to do the sides and the top.
-
Then I guess Ill have to buy a conductive pen. Will this modification void newegg/DFI warrenty?
Edit:
Will this mod only decrease the difference between the voltage found in CPU-Z and BIOS vcore, or will it also stop the jumps in vcore ffrom idle/load?
-
yes it will void your warranty as you're modifying the power delivery circuit.
if your board dies for some other reason unrelated to the mod you may be able to clean the area well enough for it not to be detected. (although carefull inspection will probably detect carbon dust under the edge of the resistor or pencil marks in the solder...conductive ink can be removed with acetone)
the basic law of modding is don't do it unless you can afford to lose it.
you should be able to reduce the vdroop with just a pencil

Ok, thanks a lot. Ill give it a go soon. You've been a really big help :up:

:cool: sure....no problem...good luck

I have made yesterday vdroop mod on Blood Iron in the same way. Everything is all right, voltage keeps stably, at strong loading under Q6600 3700MHz 1.44v rises on 0.02v a little. But at loading CPU MoBo starts to hiss and whistle very strongly!! No, it is bad - I have cleaned vdroop mod... :(
