How to overclock FSB to 550MHz on P5B-Deluxe

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

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.

Thanks your reading.:)

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

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

Maybe change SMD ohm is perfect.:)

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

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

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

what is the FSB limit without doing the mod?

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.

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

Cool, but what is safe 24/7 voltage?

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...

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.

Are these inline measurements or desoldered components?

Thx Andre!
I think change asus p5w dh..

How do you get such memory ?

any validation link andre ?

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

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

Incredible...

:slobber:

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

Marco:)
