Is the Pencil mod safe?, I rekon I can get 3.4Ghz stable if I can get the CPU to run safe at 1.6V set in bios

Is probably worth asking somebody like WJA96 who is a bit of an expert on this Mobo but ive had the pencil mod for months and there have been no issues apart from Zero VDroop :D .

So to clarify - at idle, and under full load, the vcore is identical as reported by software ?
 
So what does no Vdroop mean? better overclocks? more stable mobo?

So I guess a pencil mod is were you use a pencil and draw a line somewere on the mobo lol?

Zero Vdroop creates less voltage fluctuations towards the CPU. All electrical components like a nice steady power feed and this can help with stability, longevity and perhaps even overclocks. The mod itself consist of penciling over one resister.

Sounds scary, so its just a simple job of scribbling on one resister then thats job done? Soudns too good to be true :p

An example
If you need to set a V Core voltage of 1.6v in the bios to be stable at 3.4ghz due to a vdroop of 0.5v under full load.
So at idle you have a V Core voltage of 1.6v and under load its 1.55v due to a droop of .5v.

So after the pencil mod you can run an voltage of 1.55v at idle because it will still be 1.55v at full load due to zero droop.

This helps with lower idle temps and increases stability due to a constant feed of volts rather than it flitting between 1.6 and 1.55 volts.

Just noticed, it voids the warranty, and these have a reputation of breaking by the looks of it, so I guess if I pencil mod it, and it breaks, that's it, got to buy another one?

How can they tell if its been pencil modded? and ive only known the odd mem slot issue with this mobo, mines been fine at 1.6 to the CPU and 1.7 to the NB for months.

I've got a fan on the NB now, got it set at 1.7V, seems I had to for my memory to be stable at 1000Mhz 4-4-4-15 2.35V.

So it should be safe for me to set the CPU at 1.6V, but sounds like it could fry the E6600, but then again, its not the true voltage right? What is the true voltage whens et to 1.6V?
 
Its the true voltage. Think of it like the height of a car, put enough loads in the back and it goes down some.


Pencil mod mainly helps idle temps I think, you dont need to set as high a voltage

So doing this pencil mod wont help me overclock higher? I mean at 1.45V 3.2Ghz my idle temp is allready low enough at around 28-30 degrees and 32-34 degrees idle at 1.55V 3.4Ghz.

Yes it can help with an OC due to the increased stability of a constant (rather than fluctuating) voltage.

So atm, I got it set at 3.2Ghz and 1.45V, 8 hours orthos stable, so I am infact orthos stable at 3.2Ghz 1.4V?

Also is there something I need to do to set HDD's up on this mobo, getting transfer rates of 4mb/sec when transfering files, so something is wrong, posted on a thread on this but not got any further.

You need to check the vcore when you are clocking, speedfan shows a graph and will show any drop. It might help to stabilise that, maybe

Check the HDD are not showing any errors, speedfan does that too. If its serious then a manufacturer dos util will check for anything big but they recommend backing up data usually

The HDDis showing no errors, I dont know if I should be using the jumper pins on the HDD or what.

Speedfan is reporting my Vcore 1 at 1.46V and Vcore 2 at 3.33V, at load the Vcore goes down to 1.38 :eek:
 
Well, I feel like I want to get rid of this mobo, I dont like it, causing me nothing but hell, the damnd Vdropp, HDD problems, no profile problems, I saved an OC Profile using that Asus O.C Profile, then loaded defaults, then Bios went all crazy on me, was moving down the options, and it was as if the down key was stuck but it was not, could not do anything at all, had to reset, when into Windows, got BSOD about USB Bug Code driver or something, and next the colourfull Vista screen just before you are on the desktop was black with lines on it, and then I tried again, it froze on the screen with the orb, had to go back to my overclock settings :(

Is transfer speeds like that good?

Have you got a Hdtune graph of that drive. 4meg/s was poor ten years ago. Its a speed I would expect if a drive was about to fail or was setup badly



Does Raid work on ide or is it just sata with this board, anyone know?

C and F drive are on partitions on the same drive, now I did try transfering a smaller 1.5gb file and I got around 27mb/sec, I asked someone else who had FSX, and was also in Vista, had Raid 0 and he got about 3.7mb/sec, I onlt have one drive in my PC.


Also, does TAT work on this mobo, I always getan error message.
