How to overclock FSB to 550MHz on P5B-Deluxe

[AndreYang]

Test Configuration:

CPU: Intel Conroe Core 2 Duo E6300 1.86G
Memory: CORSAIR CMX1024-9600C5
GeIL PC2-6400 GX22GB6400PDC

H/W changes: High FSB needs high Chipset core voltage

http://www.iamxtreme.net/andre/P5B-Mod/01.jpg


Decrease the resistor value will increase Chipset core voltage.
For example:

To get above voltages, you should select the “NB Vcore� item to “1.65V� in BIOS Setup Utility.

Sweet! So we put a 5k VR on that resistor and lower the resistance to get more vNB?

[sierra_bound]

Good tip, Andre. And very nice results.:slobber:

Maybe change SMD ohm is perfect.:)

[dinos22]

:banana::banana::banana::banana: man that's very good

anyone else aside from you and sierra with these results or what

[toddm27]

very nice, I may be trying this out tonight:p:

[Ace-a-Rue]

what is the FSB limit without doing the mod?

[AndreYang]

I ask my friend, you are right. You can put 5K VR on that resistor.:)

nice mod andre. Sure beats the heck out of the gigabyte with bios voltage options that dont do anything.


DQ6-

1.6+ VCORE, fail to post

.25+MCH, fail to get past 475FSB wall. System loses total stability.

[xgman]

ES:D

well that may have something to do with it. :D

[Kallenator]

Cool, but what is safe 24/7 voltage?

[zillaoc]

wow nice find m8... :)

May have to get one now... ordered a DS3 if its a "crapper" i'll go for the P5B dlux...

TY...

[AndreYang]

Cool, but what is safe 24/7 voltage?


Dual Prime 95 5 hours is no problems , but I am not sure 7/24 in the case.

This mod should be available on any 965P board, yes? Including the DS3?

Maybe it's different because layout is different.

Yeah, I didn't mean to say that you can do this exact mod on a DS3, but the resistor in the pic that you circled above is probably on a DS3 or any other 965P board...we just have to find it :D

[afireinside]

Is this pencil moddable? Where's the read point? 550 fsb would be PERFECT with an E6400 on dry ice and in my price range :D

Nice work AndreYang!:clap:
This mobo is very interesting...What do you think of these mobo?

[775911]

The king is dead, long live the king ?

The fsb has now been overclocked by over 100% :guitar:

[Ace-a-Rue]

this mod is NOT for the faint hearted...you will need a huge magnifying glass, steady hand, low power soldering gun and a LOT of courage:D

[775911]

So a bit of conductive paint/pen isnt going to work out then :D

[railer]

this mod is NOT for the faint hearted...you will need a huge magnifying glass, steady hand, low power soldering gun and a LOT of courage:D
Plz this mod is not so hard. All you need is to solder a wire to the resistor. Now if you would need to solder a wire to a small pin it could be chalenging. I only solder to the pin if there is no alternative. Usualy i try to search for continiuty from the pin to resistor and solder to resistor instead. Anyone with basic soldering skills and $8 low power soldering iron can do this mod;)

[Ace-a-Rue]

you are a better man than me...i am not a good solderer

[railer]

lol get a junk MB and start to practice. I could not solder before ether.... In 2-3 days you will get comftible with iron and this mod will not scare you anymore :)

[Tasselhof]

AndreYang, can you post results for vMCH 1.65(unmodded, maximum in BIOS) on this board?

[ben ifin]

Hi AndreYang & tanghiro

I'm still waiting on my P5B Dlx.

Two quick questions please

( i ) Can you please post a picture of the completed mod ?

( ii ) Can you please advise the highest FSB you can get when using
just 1.65v for the MCH ?

[ Reason I ask is that BIOS 0507 allows MCHv up to 1.65, so for those of us that are poor / shaky solderer's, I'm wondering how high a FSB 1.65v will get us ? ]

Many thx,
Ben.

[Drow]

Are the OC-abilities with a “Asus P5B Deluxe WiFi� limited? Because of the WiFi?

[over@locker886]

Follow Andre's Over-Voltage Recommendation, I got FSB552:D

Please try higher multi!
Thx

[Kallenator]

This looks better and better people but I got to ask again, What is 24/7 safe MCHv?

[bugeyes]

I haven't done the mod yet but 6x500 is benchable, but 7x500 is not :( even though 3500MHz is fine at lower FSB.

[thehellrazor]

Is it any difrence in max FSB on Asus P5B and the deluxe version ??
Is this mod working on Asus P5B ?

[cpulloverclock]

Nice Andre and tanghiro :), I'm sure it's possible to reach 550 and more with no mods and 24/7 rock stable around 510-520 ;)

soon... :D

I dont get it .You have retail 6600 and you can change multy downwards to 7? Didnt know its possible i thought only ES have lower multy option.

[Moonraker™]

I'm not at all good at hard-mods, and now 0507 supports up to 650mhz BIOS NOW!

[Moonraker™]

I've just ordered it. Can't be arsed waiting for 590 SLi and this board looks far too good to turn down.

[Frank M]

I dont get it .You have retail 6600 and you can change multy downwards to 7? Didnt know its possible i thought only ES have lower multy option.
It is possible with retail, too. You just can't change it upwards; and even downwards, it's just a step or two.

[bugeyes]

Only with the later bioses, I think it has to do with Intels speedstep tech (cool-n-quiet)

what was your board max withprevious bioses

you on E6600 yeah?

[bugeyes]

what was your board max withprevious bioses

you on E6600 yeah?

bios 0405 multies locked FSB to 500MHz
bios 0507 multies unlocked FSB to 650MHz ( bit of a joke that..505 is the max I could get unmodded)

[dinos22]

i'm asking you how much your max OC changed from first bioses to the latest ones

[bugeyes]

i'm asking you how much your max OC changed from first bioses to the latest ones

Max OC for that retail E6600 has not changed from 3.6GHz using later bioses, however when approaching 500MHz FSB max cpu clocks do reduce, as to what level I have not determinded.

[775911]

Can I see a pic of the motherboard after the mod is done

[dinos22]

Max OC for that retail E6600 has not changed from 3.6GHz using later bioses, however when approaching 500MHz FSB max cpu clocks do reduce, as to what level I have not determinded.
max FSB OC i should say sorry

[bugeyes]

max FSB OC i should say sorry

shipping bios I could max out at 400MHz, 0405 I could max out at 400MHz (limited by locked multies), 0507 will only give me 505MHz though I'm sure it will go higher if I get rid of the N/B passive heatpipe.

Hi AndreYang & tanghiro - re-posting as a few of us here are asking / awaiting this info

( i ) Can either of you please post a picture of the completed mod ?

( ii ) Can you please advise the highest FSB you can get when using
just 1.65v for the MCH ?

Many thx,

You reckon that the NB is that bad then?

I was thinking of replacing it with the TT Extreme Spirit II. and leaving the voltage heaty's on. Using silver as the compound. on both. Sawing the bar off in between them.

Could you plz post the info requested above as im about to order two of these bords for new setups paired with E6400's and TEAMgroup DDR2 5300 kits, but still don't see how exactly to do the mod.

-What voltage for MCH did you guys use to get 550fsb ?
- could you please post pics of a more general (zoomed) out view, as the only pics i have seen show a wire or two attached to the resistor, not an overall view of the completed circuit?

Here is my elite image manipulation for 1.65V :banana:, is it right at all ?

My soldering skills are good but im not sure exactly what to do yet, and i think some other people need help understanding too.

Thanks very much lads :toast:

No I don't think it's bad at all... 266MHz out to 500MHz thats pretty good, I'm just trying to make the point that as I got to 500MHz @ 1.45v to the N/B any more volts gained nil mhz, that could and I stress the word could mean heat is a factor.

I wouldn't be sawing anything in half, particularly your mobos heatpipe, leave it be, but if your a compulsive tinkerer, remove it and replace with whatever, buy some ram sinks for power mosfets.

[ben ifin]

Hi AndreYang

How high a FSB were you getting with just 1.65v in the MCH ?

Ben

[adfinni]

I presume this resistor is suitable:

http://www.maplin.co.uk/Module.aspx?ModuleNo=2201&doy=17m8&C=SEO&U=strat15

Then solder the relevent pins (leaving the top one unconnected ?)

Once installed do you incease its resistance to max then turn it down until the voltage measured goes up to 1.65V ????

thanks

P5B Deluxe 4:5 has some problems. You need to use 1:1 or 2:3.:)

My ES modded mobo is about FSB 560 1.65V in BIOS, but I don't know retail box how high did it get.

My ES modded mobo is about FSB 560 1.65V in BIOS, but I don't know retail box how high did it get.

My retail board is hitting 540FSB at 1.65V, 525FSB at 1.45V. I have a modded ES board arriving that is suppose to do up to 600 although it will require a heck of a Northbridge cooler. ;)

Well yeah that seems to be the issue- total frequency still matters. Still it is nice to know this mobo can max out a E6300 chip with 7x multi. My DS3 will likely need the 8x multi of the e6400 to reach the true potential of the allendale core.

nah man even this board is not even close maxing out really good E6300 CPUs....... well at least not my mobo...the chip is priming happily at 1.38v on 3.6GHz.......this chip would most certainly go to 4Ghz but my mobo is not even close to 571MHz FSB :(

[Blacklash]

My best FSB on an unmodded P5B Deluxe = 520FSB X 7 for 3.64:

http://img206.imageshack.us/img206/6011/p5b520fsbqy5.jpg

http://valid.x86-secret.com/show_oc?id=114761

522 is where instability starts to crop up and 529 will freeze my system in the BIOS. The board will actually do a flat 500 x 7 with just a slight bump to the vcore, 2.25 on the memory and auto on the NB.

Dividers are terrible with the 0507 BIOS. I am pretty much required to stay 1:1.
