Anyone knows where are the voltage-reading-points for Vcore/NB and Vdimm?

Mike, if you look at a pic of an older NF4 chipset, there are two empty pad set positions.
Here's a pic of an older Ultra chipset to show you the pads now covered over:

just an FYI for those curious, I just did the SLI mod on my Ultra. I just recieved it 5 days ago.
I had no reason to do the mod other than to have it say Nforce4 SLI at startup...but what the hell...the mod was there and doable...so I couldn't resist. :D
:D Here's all You need my friend:Quote:

My ultra@sli mod pretty easy, i'm not using sli but so easy...i said to myself...what the hekk, why not :D ?
Made it with liquid silver...

The pic on the above Anandtech link and the one right above my post are both excellent pics of where to do the mod.Quote:

While you're at it, get rid of the crappy TIM that's on the NF4 chipset fan. clean it off real good and if you want, you can even lap it (but you'll lose the shim if you do this) and then put some AS5 or Ceramique on there. It'll drop your chipset temps a bit and possibly improve your stability at high overclocks.
I think I have enough of DFI NF4 adventure....constant freezes..etc...tried new bios/ram = zip
i've a problem with dfi & 6600gt extreme..... The Vga on SLi-mode on a A8n could bench @ 600/1300 stock cooled (with vcore mod but def voltage).....Now on DFi the vga is liquid cooled and have a vcore of 1.54v..... But it don't go up 620/1220...What's the matter?
PS: Sorry 4 my bad english....
have you tried narrowing down where the freezing is coming from? from your sig you're running your chip at 2.5Ghz @ 1.425v...tried giving a little more juice? Mine was prime stable at 2.5Ghz @ 1.45v, but would have random freezes and crashes...until I bumped it to 1.5v.Quote:

Umm... mine doesn't say anything when it comes up. Is there some way in windows I can check to see if the mod worked correctly? (I don't think I used enough pencil)
It will say it in the POST screen, right below the CPU/RAM information and right above the Drive information. Not sure how to tell in windows. The other way to find out is if you go into the Genie section of the Bios, a new option will appear to allow dual 6600GT support.
Note: mechanical pencil doesn't count for pencil modding...Quote:

My mobo is ambigious! LOL! Maybe I have an unmodable newer version. The Chipset reads, "nVIDIA nForce4" that's it.Quote:

Is it maybe the fact i don't have plugged that extra connector 5V to mobo ?
+12V is pretty low...goes even low as 11.71....any ideas ?
I've got several issues I'm hoping you guys can help me with. This is my rig:
A64 3000+
DFI NF4 Ultra D
2x512 OCZ 3200VX
Visiontek X850XT
various drives. . .
PCPC 510SLI
So I assembled the system last night and it won't even post while memory is in the yellow slots (dimm 2 + 4), and the VX won't even work in the orange slots (1+3). I tried single sticks, etc., but nothing would work to get the board up and running. I have 2x1GB Corsair XMS3200 so I threw that in; still no dice with the yellow slots but this time the orange slots work. I flashed to the 3/10 bios and now I can get into Windows with VX ram installed in the orange slots (still no dice with yellow). I installed the NF4 drivers and everything seems smooth. I do have a few remaining issues which I need help with:
1) Why won't the yellow slots work? Is there a workaround?
2) I cannot get the 4V memory line to work off of the 5V rail. I've set the jumper-block in the top right corner over to pins 2-3 but still no dice. I've got the 12V 4-pin connector beside the 24-pin connector connected. I've flashed and reflashed the bios, set optimized defaults in the 1-2 jumper position and still nada. Since I have the VX mem, you can see why this might be a problem for me, right? ;)
I'm sorry if these topics have been done to death but after 2 hours of thread-combing last night I couldn't find any answers. I really appreciate any suggestions :)
First thing to do after having all hardware ready to boot - flash bios ;)
Before that i have issues with tccd mem's and bh-5
Oh i almost forgot i've flashed with only one mem!
You have to change cpu voltage from auto to something else before you change the jumpers to get 4v memory working.Quote:

thats weird man i check all the boxes in winflash and all my stuff works fine and if i shouldnt check all the boxes what should i check?
It was weird, entering the mac address fixed it though so it was no bother
Did you check your 12V line with a multimeter? My 12V rail readings are as low as yours but my multimeter shows 12.1V. I had the same problem with my shuttle AN50R wich uses the same monitoring chip.Quote:
