P5W DH vdroop with pen instead of pencil?

Hello,

Has anyone tried doing the pencil vdroop mod on a P5W DH motherboard but instead using a conductive ink pen?

I used a 2H pencil on the given resistor and didn't notice any/much difference. I've read success stories on it but as yet can't confirm success.

What pencil did you guys used?

Thanks,

1) Use a 2B pencil
2) Are you sure you're..."painting" the right resistor ? ( show us which one you're drawing )
3) I assume that you're measuring your Vcore @ idle & full load with a DMM ( Digital MultiMeter )

1) So the lead should be softer rather than harder? I was under the impression if the lead is softer it won't stick as well to draw a line between both points. I'll rub the lead off and use a 2B pencil then.

2) I'm at work now hence can't upload a photo. But it's the one shown in already existing photos, very near to the left DIMM slot. I'll upload a pic later.

3) No, I was looking at what Lavalsys Everest reports as even if it's not accurate, it should change after the vdroop mod right?

P.S Why are you so against the P5W DH and other Asus boards?

1) It's not related to the softness or hardness of the compound.Each type of pencil has got its own resistance 'value'.

2) Ok :)

3) That won't help.Especially if you didn't do what you had to.Vdroop is the voltage drop between idle & full load.
Lets say that you're supplying your CPU with 1.455V, and that's what you get at idle, but in full load the voltage drops to 1.428V ( example ), that's Vdroop.
To test your Vdroop mod, better get a DMM and read the Vcore voltage during idle & full CPU load.
Everest or PC Probe, etc won't help

P.S. I own these boards, I kinda like them, but I hate those stupid ( mainly ) BIOS bugs, and hate Asus for avoiding the community & their clients, especially when most of these bugs are easily fixed with a good BIOS release

So from this logic it would be 2B pencils have a greater resistance thus should cause the vdroop to be improved (less).

Have you tried BIOS 2004 for this board? I flashed it and it's stable but don't have a link at hand. It's on one of the Asus FTP servers. Still doesn't fix the CPU ratio bug on Extreme CPU's though, 10x max for now.

I'll have to get a DMM.

Thanks.

Did the vdroop on 2 different boards. One pencil-mod, and one with a VR (removed the resistor from the pcb and replaced it with a 50Kohm VR)
The resistor orginally measures approx 5OKohm.

Both cards found their sweetspot around 20Kohm.

Also found Speedfan (ver 4.32) to report the correct vcore.

regards.

I used a HD pencil instead and it works like a charm, the vdroop for the Vcore is now zero o 0.1V. For those who replied, thanks for finding the time to help me out.
