I will make a vdroop/vcore mods, but i have a question:
Do i place the 50K resistor on 50K and then turn it down, or how do i start?

yes always start with max resistance when vmodding.
I am 99% sure it does, if you want post some pictures of the mod area and i can confirm it. But the board has the same PCB and layout, so i would imagine its not any different.Quote:

fully clockwise is full resistance right?dont have multimeter atm hence the question. was going to do vcore,vmch and vdroop as I can measure them all in BIOS/windows.
Does show u teh tool from asus 1,76V Vmch if the setting in bios is 1,65V? If not u should better get a DMM.
Did all Vmods now and did the final adjustment:
Vcore = 1,72V
Vdimm = 2,72V
Vmch = 1,90V
Thats fine for my cooling imho. :)

1.72V with watercooling? you are a brave man. I might run that though my kentsfield when I have a S775 kit for the MachR507a.
Already benched with 1,66V and reached 4320MHZ for 1M.
But idle temps of the cpu was 11/6°C. ;)
11/6C? have you got a water chiller there?
just a quick Q is it safe to ground all my vmods to the same ground poit?(was going to screw them to inside of case all on one screw.
1. My CPU is a really cool one and it is lapped, plus fluid metal thermal paste and i was outside. Watertemp was about 4°C. ;)Quote:

ive finished them all except vdroop. either my skills or equipment but whenever I got contact with the cap I would then short the other wire to the first by mistake. it seems hard to get hands on flux here in Oz so solder isnt flowing too great. I suppose a magnifying glass would help and good light as was damned hard to see such small components.
can some one please measure the resistance from the vcore solder point to ground through the pot set to full resistance? im only reading 1000ohms(its definitely a 50k pot and I checked before soldering it in) set to full. I havent powered the pc on yet as im afraid it will blow the cpu. maybe ive done somthing wrong but I dont see what as it looks soldered to the correct capacitor.
or funkflix can you measure resistance across vmch with vr full. also not getting anywhere near 50k. :(
Someone please tell pumbertot the original resistance between the VCore-mod points, either on an unmodded board, or just with the 50K turned up to it's full resistance. Don't know why he's asking for vmch. :shrug: He had PMed me.
Already told him my resitance on Vcore and it was 963 ohm, but i increased Vcore by 0.06V, so his ~ 1000 ohm should be fine.
yep thanks to both of you for your help. both mods running fine. also vdroop pencil has reduced it from .03V under load to .01V. just ready in time for my kentsfield thats on the way. :D
Gratz and have fun with it! :toast:Quote:

i am worrying about the vdroop pencil mod.
if stability is the only result of this mod why motherboard manufacturers do not fix it from the beginning?
i can't understand why they just don't use a lower resistance?

The only logical reason that comes to my mind is that it stresses the motherboard more. (don't know how technically)
A few times i saw something like - "intel want that Vdrop from motherboard manufactures" over the forums, but don't know if this is true... ;)
chicken out of solder.
im using my p5b in a tower case. pencil dust wont fal or anything causing short outs willl it?
Sorry, but you don't get it. ;) It's not about that one resistor. Anyways, search on google, as I said, then you should discover what I'm talking about.Quote:

cover any pencil mod with some sellotape to stop it wearing off. ;)Quote:

the thing is that WE can minimise the vdroop effect just by decreasing one resistance. Couldn't they do just this? I am not saying to use completely different parts to diminish vdroop but to at least minimise it as we do.
do you still think that I don't get it?
