I'll give you details later today OPP when I determine whether it can be onboard modded via an IC and VR or if you'll need to do an external regulation mod.

MrIcee,
Does that mean a Chipset mod??
OPP
Yes...I'm not sure yet. It might be able to be modded like the EPoX. I need to determine which Mosfet has the Vdd output voltage, then find the IC Voltage regulator that controls it. Next up is finding out what IC brand and model #, and what pins thru datasheet research.
There is a Mosfet and Voltage regulator between the AGP slot and first PCI slot...I believe thats for the AGP voltage.
Theres another Mosfet under the CPU socket toward the back of the board. I'm not sure if thats Vcore or Vdd output.
I'll keep you updated, still awaiting my board:)
Randi:D
I'm at school right now, maybe by the time I get home you'll have it figuerd out before I install the mobo in the Prometeia :)
OPP
NF7-S owners !
I need a favor please. I just recieved my board and verified my voltage circuits work . I have the bare board in front of me without anything installed as I'm measuring voltages. What I need to know is what your AGP and Vdd(chipset) are set at at default....and what the other choices are. So I need default bios AGP voltage reading in the bios, plus all bios voltage choices. I also need Vdd default setting plus the other choices. Thanks in advance !!
Randi:D
Nevermind y'all:)
The AGP mosfet is under the power connector....just confirmed it. I'm turning to the Mosfet and IC between the AGP and 1st PCI slot. Looks like this might be like the 8RDA+. I'll check back in soon.:)
Randi:D
Glad it worked my man. Rip'emQuote:

I think for the NF7 we should start with a 200 Ohm VR if any one plans on doing it.
Any word on a chipset mod ?? :)
OPP
AGP doesnt need more Voltage, it has up to 1.8 which is fine. The VDD (chipset) needs voltage though, I forgot the default but it goes to 1.7 in bios. You can't read it from the bios either.Quote:

Hay yea Turbo, I'll be bring by the Epox next. Pretty much the same mod for the mem voltage. ;)Quote:

Thanks to MrIcee I'm now sporting all the chipset voltage I want on the NF7 :) Between this and my mem voltage we should see some killer FSB out of this mobo.

OMG...if I hear a sonic boom all the way here on the east coast, I'll know where it came from.
Hi guys:)
We have a Vdd mod folks:) OPP just mailed me and confirmed that it worked perfectly on his NF7-S. In the next day or so I'll have a guide for everyone to go by in these endeavors. All we need to do now is overcome the OVP on the Vcore regulator so we can achieve higher than 2v.
Thanks OPP for taking the chance on doing the mod, it's greatly appreciated. I was unfortunate and smoked my board as happened to a few EPoX guys after running too high a voltage. Funny thing is...OPP is using less resistance than I did....I thought I was too low to start and hence too much voltage. Who the he*ll knows...LOL I'm just glad it works:) I guess when I send this back where I bought it..I'll have to tell em it was DOA;)
Randi:D
EDIT: Guess I was better late than never:)
keep up the good work

In relation to to Vcore mod, with pin 7 and pin 10 mod's in place and the system running at 2.0vcore, what is the voltage on pin 10?. Looks like you need to maintain less than the bios vcore setting + 15%, and you should be able to check that on pin 10 and adjust the VR as required.
Also if this is correct, you'd want to be using a 500ohm VR?Quote:

You might try doing just the pin 7 mod to begin with, and see if you get any voltage changes.
If that is in spec, then it could be suffering from Over current protection which probably just involves another three resistors on the ISEN legs (3 phase power) :(
Great work again, MrIcee! :toast:
and what about your external Vmem circuit? already installed it?
:banana:
Great work MrIcee! :). Now as you said all we need is some 2V+ Vcore.
I tested my external Vmem mod first and it was working...I had dialed approximately 2.95v initially. I then turned to the Vdd mod, figured it out, executed the modification but toasted my board in the process. I have another arriving today so I will give everyone the definitive thumbsup after I run for awhile with it hooked up. The Vdd mod is safe and sound, my external voltage regulation for the Vmem needs a few hours testing before the final stamp of approval. As you know, OPP did get the mod done for Vmem by having the Pin 19 mod done on the Winbond 3330 which for the average guy is a nasty, cramped position modification. The External voltage regulator circuit I came up with is easily built with parts from Radio Shack by almost anyone...and only involves soldering 1 wire to the motherboard in a very easy place.Quote:

Nice will appreciate the positioning of the mods, the circuits are simple :) Hopefully the holy abit will be avail on my return...
Hoping to get some benching in after vacation, im off snowboarding :)

Randy your burning the candles a little later than usual this evening/morning. Glad to hear about the success on the mods. Are you still going to run some marks on the 8RDA+? I would like to see what kind of results you get out of it before I make my final decicion on what to do with this NF7-S that I have.
On another note I still haven't heard anything from Chip-Con yet. I thought they were suppose to be "Great" in the customer service department. Well maybe tomorrow. But you would think that they could of at least acknowledged the fact that I sent them 3 E-mails and said that they would look into the problem. I am not impressed. I do appreciate the help that you have given me and in no way do any of the above statements reflect on you! You definately went out of your way to give me a hand and I just wanted to say THANKS again.
Nate
Nate:)
I had the day off today...but got up early due to a bit of snow to call my boss and see if I was needed for a couple hours...but I wasn't so I jumped on here for a bit.
Unfortunately Nate....You are not the only one with NF7-S/8RDA+ problems with the Prometeia. Not everyone has a problem with those boards in the Prom. I have had the 8RDA+ and OPP has had both the 8RDA+ and NF7-S in his no problem.....but others like yourself have not been so lucky. The delayed response is more than likely because they need to recreate your problem(and others) themselves to find out whats happening. I agree they could and should acknowledge your emails. I wrote them directly myself and have got no reply yet either.
I can assure you tho after seeing others with the same problem, that they are working on a solution for everyone. My hunch that it has to do with the circuits on the nForce2 boards in some way may not be far off. I will drop another line to them on your behalf later today and try to get an answer for you.:)
Randi:D
I thank you friend, but don't put yourself out. I am going to try the method of starting the board with a normal heatsink and fan let it post shut down and then instal the Prom and see if it works. Remember, I also experienced the problem on my KD7-E which ran just fine for almost a month prior to this happening. I have to go on one more service call and I'll give it a shot when I get back. I was just inquiring on the 2 boards, because OPP never did say what he thought of the 8RDA after his attempts to publish his scores or if he was continuing to push it. I can understand though, what good is a score if you can't publish it. Have a good one.
Nate:D
well, i wanted to order NF7-S yesterday, but decided to give Asus one more chance after hearing news about new 250fsb bios. I just want to run few Sandra mem benches and compare them to Abit/Epox just for future reference. If this one dies, NF7-S will be my next choice:) I should be able to finally run Prometeia powered benches again in max. 10 days, i hope.
Did this at 220x13 on the NF7.
And no, it can't be published, I tell you, AMD just cant get a break, the Damn ORB must be sponcerd by Intel.
