P5B Deluxe Vmods

[ManagHead]

I did the mod too.

Before (1,45V in bios):
1,387V orthos-> 1,373V
After:
1,412V orthos-> 1,411V

Alright, I decided to rub the hell out of that little thing with my pencil.

I'm getting no vdroop reported by asusprobe. Vcore stays at 1.51 all the time

Nice, what have you set in bios?

[giovysax]

HI GUYS,
i have a question: safe range for vmch?
I measured vmch after mod with multimeter: 1,79volt real -> 1.65volt bios
how can i reach over 500 fsb?

sry for bad english

thx cya all

welcome to XS Can you not hit 500FSB at that voltage? for much higher voltages, i`d suggest improving the cooling on the chipset

Yea, my first tought too. I managed 505 with cold air, with normal air temp I can't get over ~495 with any vmch/vfsb.

1.5375 or something like that. The mod sort of fixes the board's undervolting, but not that much.

lol, magic forum
thx for fast answer
without vmod i get ~500....with mod vcpu, vdroop, vmch and vddr i get ~500 too ----> 505 black screen
i have liquid cooling on cpu, northbridge and vga
can i reach 500+ increasing again vmch or i break my mobo?

Thx, thx, thx!!

other voltages? other settings? you don't give much info , you might have something else you can tweak.

Thats a bit weird What BIOS you running? water on the chipset should definately get you past 505, tho from what i`ve read here, board performance ranges wildly from user to user?

i think it is your cpu that limited

[giovysax]

Well....

1° config:
BIOS: 0804 ufficial
CPU: E6600@3,5GHz 1,55volt 500x7;
Vmch: 1,78volt (bios 1,65volt);
RAM: 1000MHZ 5-5-5-15 1:1 2.45Volt (bios 2.35volt)

If i set 500+ black screen

Actualy i use this config:
BIOS: 0804 ufficial
CPU: E6600@3,84GHz 1,55volt 480x8;
Vmch: 1,78volt (bios 1,65volt);
RAM: 960MHZ 4-4-4-10 1:1 2.4Volt (bios 2.3volt)

thx for help xD

cya all

[giovysax]

well,
after various test i inderstand that my limit in overclock is SoutBridge Vcore!!!!
If i set it at 1,8Volt i can reach 500MHz fsb stable with vmch=1,55V, vcore 1,50volt, vddr=2,35volt!! (orthos run for 7+ hours)v

If i set it at 1.7 is not stable for me.
With sb vcore 1,8volt i can boot at 510 but is not stable with orthos

any southbridge vmod???

thx for help!!

(Merry Xmas and Happy New Year!!!! )

[ManagHead]

Interesting, I'll try this myself. Time to put watercooling on sb, and tec on nb?

I was able to pass 500FSB without cold air with southbridge 1,8V! Haven't tested anything else than Pi 1m. Nice find!

Thanks for the info..

[OnDborder]

Just checked mine. Set at 1.525(in the bios) reads 1.48 with programs. Load it drops a little, to 1.464.

Do I need the vdroop mod?

[OnDborder]

Did the pencil trick. It took more than a couple of times for it to stick.
Before I'd set 1.50 in the bios, I'd get 1.456.
Now, 1.5 I get 1.48.
Before 1.480 idle, 1.464 load.
Now, 1.480 idle, 1.472 load.
Not that much difference.
Maybe tomorrow I'll crack open the conductive ink.

what mods can you use conductive inc for?

[Viss]

Have to try that pencil mod. SB voltage does help for a few more FSB mhz. A good cpu as wel Me first one did 505 orthos, 510 dual 32M but bsod at 512 or higher... Second one does 550 stable on air and max about 570 1M with mach. Same board/mem/bios/settings.

[jVIDIA]

I think no mod can be done in the P5B with conductive ink.

[OnDborder]

Instead of using the pencil, thinking about using the ink instead, on this vdroop. It's more reliable.

[jVIDIA]

It's not the same thing ! be carefull !!!

The pencil reduces de resistance a little bit. The conductive ink reduces the resistance to 0 ! If you do that it could fry your CPU

[OnDborder]

Ok, I'm just a little confused. Help me out, please.
When using pencil lead aren't you connecting the 2 posts, by passing the resistor? So you can "control" the amount of resistance with the amount of pencil lead applied? A little lead, little resistance, rubbing the heck out of it, alot of resistance?
I thought either the current bypassed or it doesn't.

Maybe that explains the different readings. Like I stated, it took a few times to get a stable vcore. One reading would be 1.509 then fluctuate to1.49. Another try it read 1.3 when set to 1.5, maybe too much pencil?
Now it's pretty much stable at 1.48/set at 1.5.
I guess I got lucky and used the right amount of lead.

i don't boot with fsb 510+

help me?

You should just use a trimpot, its alot safer.
