ASUS P5K Deluxe Vmods.

[SF3D]

I am trying to confirm if some of these mods are the same for the P5K Prem too. The board layout and components seem identical to the Dlx, but use diff brands.

Can someone with a Dlx measure the PLL and FSB VTT points and tell me what readings you get at minimum BIOS setting for them (not AUTO) and then 1 or 2 steps up? Neither of the voltages I measure on those legs on the Prem ever change no matter what I set the Vpll or FSB Term to in BIOS. No one else here seems to have done the mods on a Prem yet, so I am curious if I just need to look for different measure points on the Prem or if I need to dig further than that.

See my thread here for additional info/pic of the Prem board if you can help out

You should try to do vsb mod, cause your vfsb read point is actually SB readpoint. (in your thread -picture 1) Mod point is under the PCI-E connector.

Vpll mod is working right on my P5K dlx, so maybe you just try it on premium and let us know if it works. If I remember right, the ohm value in mod point was 1.1Kohm. I have the right values somewhere if you need them.

The answer is yes

And could it be the same for the P5K-Premium ?

Thanx, regards

pepinorang- It should be same.

boostedevo- I will answer your pm later this weekend.

i tried to mesure the vdimm...

is it normal?

2.30v Bios = 2.16v Idle / 2.14v Load

[boostedevo]

That seems pretty weak for sure. Mine is right on the money (2.30V set = 2.298V measured), but 2.55V setting = 2.59V actual. NB is the same, right on at lower settings and a bit of an overvolt at higher (1.80V setting = 1.89V actual).

boostedevo- I will answer your pm later this weekend

Thanks, any help you can offer is much appreciated!

Sorry about the noob question, but could somebody tell me EXACTLY where to put the red lead, and exactly where to put the black lead, for measuring vCore based off of

...this is my first time using a multimeter and I have no clue where to even start.

[flaker]

hmm, I still have a vdroop after vcore damper enabled.. Any suggestion for vdroop pencil mod point? I already found a P5K vdroop, but the layout of deluxe is different..

[Counter CS]

Hi, i want to know what Vcore i´m using.
I pute 1.225v in BIOS, and get 1.19 idle and 1.184v Load
On my DFI 965P Infinity Dark-s this CPU needed 1.221v to pass Orthos.
But i became confuse with this new mobo.

You can see what i'm talking about in this pic.

Hey
I had same issue, and I've found all required information for pencil mod on P5K deluxe in this thread:

[Pete]

I think we need the mods conferming and tidying up in here..anyone agree?

[Gligy]

The Vdroop mod in the other thread is wrong.
Here is the right place.
Before mod it reads 48Kohm after 20.5Kohm
With q6600@3600
Before
bios------idle------load
1.5v | 1.474v | 1.448v

After
bios------idle------load
1.475v | 1.480v | 1.464v

[Gribo]

Ty - it was really helpfull !

[Counter CS]

Where do you read the Vcore ?

[Gribo]

I read it with ASUS-PC PROBE program.

[sobol]

Guys, what is the proper vdroop pencil mod for P5K deluxe? ( i don't want to solder anything to mobo ). I'm confused with different versions.

[Gligy]

In my previous post the resistor marked with yellow, I've used HB pencil to take it down to 20.5Kohm and it did the trick.

This pencil mod it's in the same place at P5K-E?

[Gligy]

This pencil mod it's in the same place at P5K-E?

It should be, virtualy it's the same board. Measure with multimer the resistor if it reads 48-49Kohm then it must be the same.

[RaMmElEe]

This pencil mod it's in the same place at P5K-E?

Tested and confirm work great on P5K-E
Thanks Gligy

bios------idle------load
1.3875v | 1.392v | 1.384v (voltage damper enable)

[Chri$ch]

hello guys,

which pll voltage (for P5K-E) is safe or critical?

[SF3D]

I have tested PLL voltage up to 2.4V without any problems. So ~2.0V-2.4V should be safe enough.

till how much Kohm be safe??? looking to do this one... my first time.

and what does PLL voltage contol?
Thanks in advance

[dpa]

is it possible to solder a pot instead of using a pencil...? if so, how high res..?

[Gligy]

You can use 50Kom in parallel the resulting resistance should be around 25Kom, according to my calculations (original resistance is ~48Kom).

Best Regards.

Please can somone conferm Vdroop, Vcore, Vdim, Vmch and other mods that work, pohoto and what parts needed. I'm getting so manny dinffernt bits of info and need to mod bord ASAP
