Hmm, where did yo uget the pot from? And also, I know it sounds really obvious but you are turning it the right way to lessen resstance...i have a pot that doesn't stop turning.Quote:

i got it from radio shack and i am turning it counter clockwise i think it is the right way and mine doesn't stop turning either which way are u turning yours?
It all depends which of the two hot pins you decided to use. I'm not sure if right/left is clockwise, but if you have a multimeter measure the resistance turning it both ways, but you have to take the grabber off first. If you dont have a multimeter, then it's gobba be hard to tell, and all you can do is try both ways and see which raises voltage.Quote:

EDIT: Hold on, are you using a hot pin and ground pin to connect, or using both hot pins? If you use both hot pins it will give you a set 1k resistance no matter what you do.
i am using the middle pin as the ground and one of the side pins to go on the chip
Did you read one of my previous posts (the long one)
if you didnt that will explain how a cermat pot works and how to ue it.
If you have any questions feel free.
Use the ground to connect to the ground on the actual chip...pin4 I think it is, furthest from the DIMMS on the same side as the pin you already connected to...That could be your problem, not sure. Also, try turning it the other way or read Holst's post like he said.Quote:

clip the grabbers onto the + and - of a multimeter (digital preffered) and turn the pot while watching the multimeter, that will give you the direction and if its working or not...
How do you have the wires soldered to the Radio Shack pot? If you don't have the SMD grabber wire soldered to the middle post, it isn't going to work.
i just check the resistance with the mm and it said .371 is that hogh low or what and i am turning it the right way also i have one wire in the middle and i am using it as the ground
Use the middle pin to connec to the ground ON the chip that the other pin is connected to...The ground pin on that chip is the last pin on the same side as the one connected to your right/left leg on the pot. It should be the one furthest from the DIMMs. Also i'm assuming it says .371k, so 370ohms is far too low! Adjust it to 780 Ohms for a nice, safe voltage, then do what I decsribed above :)Quote:

i had it grounding on the hs for my nb cause i broke that smd grabber. could that be the problem?Quote:

Yes, absolutely! The NB is not a ground.
I'm not 100% sure, but I assume that's what it is...Do you have aan extra SMD grabber you can use? Check if that heatsink has 0 Ohms btw, it might not even be a ground.Quote:

Ok, if you broke the ground SMD then just cut the wire and put an electrical grommet type on that cut end. Now attach it to any place on the case or to one of the m/b fasteners.
You don't have to attach it to leg 4 to make a ground for a complete circuit. It can go to the case or m/b mounting screws.
no i don't i ordered 3 from outpost.com/ frys and they are on backorder but as soon as they are in i will get them overnight
so where else can i groung this ire can i put it on my case?
ok will try that nowQuote:

This is starting to scare me now.
Please stop and read some more stuff before you continue King, it soulds like you have allready come close to killing your board. Better to stop and work out what your going now rather than break something.
Yes, yes, yes put it to your case!!:)
i did it and it is running at 1.82 vdd now thank u everyone for your help i don't know why i thought the hs was a ground thought i read it somewhere right now i am at 215 fsb thanx to u guys and do u guys think i should post this on my website it should be up and running tomorrow and for some reason i am getting alot of hits and it's not even up yetQuote:

Great to see it worked out :)Quote:

Is it possible that the MB burned up because something got loose in the mod and shorted out? Or maybe a combination of mod's?
If you don't use a multimeter to set the screw/ohm before installing the mod, you are just working in the blind. It is much safer to set the screw outside the board on a multi meter and then put it back.
I set 740 ohms on my 1K from radioshack and then installed it. It went form stock 1.58-1.6 to 1.82-1.84. So far no signs of trouble. I do have a crystal orb on my NB. I wouldn't reccommend this mod with only the stock NB heatsink.
Yeah, time to rev up those 6K 60MM fans.:D
I'm running @ VDD 1.56V with 220.
What ohm do I need 2 stay save?
I'm cooling the nb with water.
What FSB could I expect?
I'd like 2 run @ 10*230.:D :D
Rich,
How were you grounding the mod? If you were chip grounding then maybe that's overloading another component?
Holst,
I'm scared too :D , it's nice to see people getting involved and it's the only way to learn, but I can see alot of fried boards if people don't take a little care. I know it's dangerous, but check other components with your finger to see how hot everything gets after a mod, and add little heatsinks and fan cooling as appropriate.
The 8KHA+ vcore mod is a classic example, the vreg chip and mosfets were cooking at about 1.95+ causing instability.
Grounding from a fan connector.Quote:
