P5B Deluxe OVP mod

[blind_ripper]

so can some one now make a clear pic how we should mod a P5B for OVP ?

[massman]

No one knows the modification. I could sure use it this friday:-)

Any news on this, found a Premium

Try to use schematics in last loopy83 post. But except Hipro maximizer just hook that 500 ohm (better VR 1-5k) to quiet +3.3V. You will get 132mV extra.
No warranty tho, have P5B atm to check. But it's easy.

interesting thread
I'm back to overclock and i'm waiting for i7 setup, anyway i'm playing with a p5b dlx (i like old school mobo) but i'm a bit confused, can someone tell me again how to bypass this damn ovp? I'm limited to 1.936v and i hate limits...
Thanks in advance
Edit: I'll try to connect a 500ohm resistor from pin 3 to 3.3v rail... i hope it'll work

[c1rcu1tburn3r]

Ok, officially IT WORK! Thanks

So what voltages was without mod, and now? Tell more

[c1rcu1tburn3r]

i'd +0.230v with normal vmod, than passed from 1.7v to 1.93... after the ovp i had to low down the voltage in the bios till 1.62v so i can have around 1.97v on cpu-z (vmod+ovp)... or you can set again 1.7v on bios and turn down the vcore mod it's the samething
Anyway with this ovp mod you can go higher than 2v without problems

If can help...

c1rcu1tburn3r, so it's 3,3V rail?

Yes, sorry i forgot to write it... is the 3.3v rail (u can choose one of the orange wires pins)

My version of OVP mod on P5B DLX

Got 2.1V on celly 356, and this allowed 8127MHz clock archivement from my hwbot teammate.

Thanks a lot for sharing , got a simple question before i give this mod a go. If i got it and understood correctly 1K ohm VR trimed down to 500ohms conected to 3.3v rail , but the other end of the VR im not clear where to solder the other end ? Can you please provide a clearer picture if possible and explain exactly wich point to solder the other end of the VR ? Thank you in advanced c1rcuitburn3r , appreciate your help very much. I just want to be 100% sure on this mod as i have a dead P5B-Deluxe already but i found a new one on e-bay and bought it , this new board looks very promising for high fsb and i dont want to kill it as they are hard to find good P5B-Deluxe boards. cheers M8.

Kind Regards: Angelo.

Yes, you've to connect, like in the picture, a 1kohm vr setted to 500 ohm from 3.3v rail (under the atx connector) to the pin #3 of the chip (adp3198)... i think is clear in the picture, just look there and see the two red lines i've done with photoshop ...

I tried this Vcore mod on my last Commando and it was working...maximum vcore was around 2.06V on my E5200



next time, I want to try combinate Vcore mod and Vdroop mod and I will see, what will be maximum Vcore for Celly D 347

[joker_v3]

There's something that I don't understand: should we do just the OVP mod or make the OVP mod + vmod to overtake the ~1,95v ??

You need vCore and OVP Mod.

[TiN_]

OVP + Vcore of course. OVP just level up protection shutdown limit.

ok thank you guys !

If can help...

I thank you for this.

Edit: nvm. should have read before posting.
