Droop mod

P4P800 solder points

Done

P4C800 points

Well the amount of voltage drop depends on how the 'droop mode' of the regulator is configured. Mine used to drop from 1.76 to 1.68V under load but now with adjusted Droop it stays at 1.76-1.74V all the time

around 28kohm will give idle=1.76, load=1.74V

I used 500k VR set to around 28k

I'm guessing the P4C800 has a vcore under volting problem such as the nf7-s eh?

How lucky am I to have known someone who is so hard to say good-bye to.

this seems intesting to me. although what performance would be gained from doing something like this?

If your cpu/system is stable at 1.76vcc but the board drops you to 1.68vcc under load You loose stability. Keeping the vcore closer to where its set under load will keep the system more stable.

I am liking that mod. I believe the p4p800 is in my near future, and I will have to give this vmod a look. Thanks buddy!

What is this phrase "Running Stock" that you speak of?

Nice. I wish there was something like that for my NF7-S.

if you happen to find anything on the is7, feel free to let us know!

Thanks, that was the Mod I was looking for!..

That should Finally get me over 300FSB on my P4C800..

well, I am going to get The Pots today for the Mod.. Mine is dropping from 1.65V No Load to 1.56V Full Load..

Also Pulling That (*&)^%^$ Water block off the Radeon 9800. That is heating up the water way too much for Stability on the cpu..

reply to Exit
why exactly do mobo makers do this? is it like a safety issue or something to drop volts under load?

well, Just finished the Mod and it Did Absolutely nothing for my Overclocking.. Still cannot get over 300FSB..

Vcore though is Much more stable

But Corrupted the Bios twice when I switched from 1:1 to 5:4 Ratio..

Take any pics?

I don't thing the cpu voltage was holding you back. I think watercooling the NB and good cooling on the cpu is the only way to get over 300FSB stable. Also you have to up the agp/pci speed to 70Mhz before you up the fsb over 300. Also if your on an S-ata drive you won't be getting over 300 because the controller dies
