NF7 Voltage read points

[ricjax99]

I think i have this right but could someone confirm what the 3.65V reading is. I'm inclined to believe that it's the +3.3V dual, as it shows similar. And if someone could point me to the +5V rail reading.

I have to resort soley to multimeter at the moment my h/w monitor/bios readings are way out only one thats about right is vcore.

Bios settings:

VCORE = 1.93V
CHIPSET = 1.6V
VDIMM = 2.8V (10K VR)

h/w monitor/bios readings (under load):

+12V = 11.67~12.10V
+3.3V = 3.25~3.34V
VDIMM = 2.99V~3.06V
VCORE 1.84~1.94V

The readings on the board (pic), are rock solid apart from the +12V and +3.3V(and thus vdimm) which drop under load.

3.44V drops to 3.36V (and vdimm to 3.10V)
12.40V drops 12.04V

The PSU is an unmodded Enermax EG465AX-VE-(G) 460W 35A(+5.0), 35A(+3.3V) and 33A(+12V).


***WARNING, WHEN CHECKING THE +12/VCORE MOSFET BE CAREFUL NOT TO SHORT THE TWO LEGS THIS WILL KILL YOUR BOARD 100%***

Heres the pic:

Heres a prime pic with readings as you can see the are really odd, i cant see my +12V dropping below 12.04V on the meter

You show a large differenc in the Vdd voltage between the 2 spots.

Thats a 0.2v difference. The mod would settle that in for you I think.

The rest of your voltages look fine to me.

I dont follow what you are saying here.

DMM's are much more accurate than the bios/software.

The DMM, however, may also not have a high refresh which means it only responds the the voltage dips it catches, if any.

My +12v rail on the board when priming doesnt drop below 12.04V but in MBM (Same as bios readings) shows it dropping to 11.67V , but like stevil said it doesnt refresh as much. So it may be fluctuating but the read point doesnt refresh quick enough.

Theres a bit of graphite on the vdd resistor that accounts for that. Not sure which one to belive tho

I would always go with a direct measurement off the hardware.

Yeah so would i but i'm still debating which of the 2 vdd points is more accurate

put a DMM on each and see

I dont have one as far as im aware

EDIT - bah thinking a DMM was something else LOL

I have checked them, one reads 1.62v other reads 1.81v like the pic.

Thats an odd reading.

Mine are pretty close to each other. Within millivolts.

Out of curiousity, I checked it on a modded Vdd and an unmodded Vdd. Still the same result...within millivolts of each other per check point. I thought at fist maybe the mod steadied it out or something...but not the case.
