This worked a little to well for me, i have a pentium d805 and under load it would go from 1.60 ( selected in bios ) to 1.32.
But now it does this; i set it to 1.6 in bios and under load it goes up to 1,75

did you do the pencil mod? If so check your resistances. You only want a resistance of between 20 and 30. I have found that 25 works very well for me.Quote:

first i wasnt able to do 3300 stable now i'm doin 3900.
one thing still bugs me, my bios says 1,7
cpu-z shows 1,7
everest tell's me its 1,45
to be honest i believe everest. I'm running on air cooling and temps are max 67 deg. not lapped cpu. I dont think the vcore is right in cpu-z and bios, because i know other people wo are doing 3.6 or so and have a temp of 75-78 with same cooler and 1.5 volts
you would believe freaking everst over cpu-z ? yeah uh huh.. sure..
67deg ? your gunna kill that cpu.
and if you saw others running 75-78deg then they are ,,, well i wont say retarded but thats what i want to say and so are you if you think those temps are ok.
your gunna shorten its lifespan if you keep running at those temps.
and you may be seeing some thermal throttling going on at those temps.
if your bios says 1.7 then thats what it is
and god help you if your running 1.7v on that cpu on this motherboard.
yes the Pencil mod reverses the droop so now its not a droop its a *insert funny phrase for a reverse droop* its an increase.. and once again your running 1.6v on that cpu your nuts especially on air
i wont even go over 1.5 and im on water
need to lap this cpu, mayby it would give some better temps. but a'm not verry concerned about the lifespan. i'm going to get a conroe when they come out and a celeron d 356 in a week or 2.
btw if i go back to 3,0 ghz and set my vcore to auto i get 1.5 volts and 65 deg.
btw 2 , i should probably tell you my room temp is currently 38 deg ( live on attic next to dry'er,washing machine and tanning bed )
AARRGG Fowers in The Attic!!!
so how the hell do you get above 1.5v with this mod.. its really pissing me off and limiting my overclock.
i only need 1.42 to run 4.5ghz stable but i cant get any higher unless i hi 1.5v and i cant with the pencil mod. the system wont even boot with 1.5v
i had it higher than that prior to the pencil mod. so i know its the pencil mod doing it.
the way i did it was like this :
------------------
| | |==| |
i tried to drew small ( miniscul ) lines between the two pins, you cant actualy see, you have to do it using one of these
huh ? were you replying to someone else as i didnt ask how to do it i asked how to get past 1.5v the mobo wont let me. it just bombs if i try
im gunna pull this all apart this week and send it to proth to mod so im not all that worried but if i can get away with NOT destroying the warranty i would prefer that.
The resistance has been lowered too much... This is why it's best to use a VR if you have good enough soldiering skills. ;)Quote:

well i have done the pencil mod.
i have got 0,1V incresement.
my 940 Presler runs at 290FSB 4640Mhz Stable with watercooling
but i want to reach the 300FSB or more.
actual settings:
VChip 1,6V (PCI-E)
Vcore 1,3V (1,4v measured)
VMem 2,1V (don't need more bcz of hot chips)
P5WD2
G.SKill 5400 GBHZ
940
any tipps?
can someone give me information for incresements ?
thats very low volts you need to raise the vcore.
everything else seems ok
whats your FSB speed ? like 1160 ?
okQuote:

load up to 75°C
well and it's seems to trottle bcz of overheating
so i'll select 4,5Ghz with 1,325V (measured)
Is there also any non-hardmod to get more vdimm in the mem's on a P5WD2 Premium ?
only possibility would be to do a direct wire from the 3.3v line to the vdimm which would lock your vdimm at 3.3v and kill any ram you tried.
i dont know why you need more vdimm. this board gives enough vdimm for all but one type of ram that can handle high voltages.
other than that you'll just kill your ram.
Lestat, 2.3v is not enough ;)
lol
its a hardware mod only bro.
yes. I only wanted to know if there was a possibility of doing that mod in some easy way like the pencil vdroop mod ;)
I just did this mod...works like a charm! Some weird things happened though. I couldn't get the tip of the pencil to stay in between the pin points, so I kinda just rubbed it in. The voltage is now completely stable, and it actually reports about .11v above what's set in the BIOS. I don't mind it though since the voltage report is stable!
see if you can go over 1.5v
whatever setting in the bios you need to use just try to go over 1.5v real voltage.
mine wouldnt boot or it would reboot if i went over 1.5v
its like its too much voltage and the pencil mod causes it to fail
Ive tried this mod more then half a dozen times and not really had great sucess so far.
It could be because my system is less then perfect but Iam testing it after reapplying the mod, cpu, thermal compound and some light lapping on the IHS.
Seems to be better this time but Iam not that hopefully really :/
So far, winrar benchmark is almost a flatline on vcore but it just blipped from 1.39 to 1.41. 1.3375 in bios is set
S+M is the ultimate test and that switched my pc off in the past. My zalman heatsink has no heatpipes so I know that is lacking, at 2.72ghz Iam getting 61c. It throttles at 65.
If I get sucess, I will update with speedfan vcore graph.
edit:
Nope it crashed after I closed winrar and temperatures were falling. The northbridge heatsink gets hotter then the CPU one despite me placing 3 small fans around it, should I try reseating it ? If it was bad contact then surely it would not be getting hot!
The vcore does not fall from 1.39 even though the bios is set to 1.3250v now.
thats WAY!! to hot man your hurting that cpu.
go spend the money on an XP-90 or a Big Typhoon.
those are the only ones that i know of that cool it good enough.
and whats the problem with the droop mod.
it does exactly what it is supposed to do,
i stops the droop mostly and reverses it into an increase.
it obviously is supposed to do something else from what your thinking and its not. if you want the proper mod then do the hardware mod or have someone from here do it.
its called a ghetto mod for a reason, it has issues but it still works.
I found the crash was caused by corrupt software (I think) from previous crashes so Iam retesting.
I know its too hot but at 60c it should still be stable as it has been in the past with no mod. (Its idling 35c presently)
Iam not complaining just pointing out difficulities Iam having that others might too, its a budget system which is why I appreciate the ghetto mod but I cant upgrade the HSF quite yet as I just brought some ram
I havent found any vcore increase under load yet but it is looking a bit more stable now so I'll continue testing and report any sucess I get.
edit: froze again after dual sp2004 had been stopped when trying to load another program
Giving up for now as its more unstable with the mod then without, I'll try again once I find a proper 2H pencil
Yeah, over 1.5v is no problem. I have my 805 at 3.9ghz 1.6v now...70C load under AS Ceramique and BT. These things run hottt...but I know Intel's can take the heat (esspecially the 90nm ones).
From what I can see, the mod doesn't really help my overclock though. 4GHz is still unstable with the first core. I have an untested Ninja here as well...and I need to get some sandpaper to do lapping on these sinks. Maybe then I can get the big 4 before I go conroe.
