No one knows the modification. I could sure use it this friday:-)
Any news on this, found a Premium :D
loc.o
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. :D
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...:D
Thanks in advance
Edit: I'll try to connect a 500ohm resistor from pin 3 to 3.3v rail... i hope it'll work :D
Ok, officially IT WORK! Thanks ;)
So what voltages was without mod, and now? Tell more ;)
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)Quote:

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.Quote:

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 :)...Quote:

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
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 ??
Thxxx
You need vCore and OVP Mod.
OVP + Vcore of course. OVP just level up protection shutdown limit.
ok thank you guys ! ;)
I thank you for this.Quote:

My version of mods on P5B DLX, prepared for cedarmills :D
TiN_EOF, voltageregulator for stable OVP?
yes-yes, details are here http://www.xtremesystems.org/forums/...90&postcount=1 :)
