So just to confirm, even if applications like GPUZ show your power states fluctuating and lowering when idle they are incorrect when the mod is applied? I was under the impression that it was AB that was incorrect, ohno-smiley02.gif
post #452 of 464
is anyone having trouble with afterburner beta 18 and going above 1.3v even with the new tool?

The volt mod and consequently Zawarudo´s tool work thorugh AB interface to operate the voltage controller NVC4206, so, only AB is linked to the controller getting the accurate readings from the monitoring chip INA3221!
All other programs get their readings from driver feed and as you well know are locked to 1,212V, so anything beyond that is not read!
Here, read my article about TDP:

"The PT is the increase of TDP (thermal design power) which is determined by the chips maker (GK110 =250W) but this is not a fixed value, refers to the maximum amount of power the cooling system, in this case a chip, is required to dissipate. The TDP is typically not the most power the chip could ever draw, but the maximum power that it would draw when running "real applications". This ensures the chip will be able to handle essentially all applications without exceeding its thermal envelope, or requiring a cooling system for the maximum theoretical power.
"TDP is meant to be the wattage of the processor at load. I say "wattage" because it is unclear if this is meant to correspond most immediately to how much power is consumed in watts, or how much heat is produced in watts, but as near as I can tell the TDP is pretty much meant to indicate both" GL



(where C is capacitance, f is frequency and V is voltage)

Now, you dont have to make complicated calculus or anything like that because you have this chip here:



It monitors real-time voltage and power draw and its where AB gets its reading from the VRM´s! wink.gif

Stock bios come with 250W TDP (AKA PT) so when its at 100% you will have 250W of power draw, if you increase it to the max stock 106% youll get: 250x106%=265W
The same is with modded 300/400/500W bios what you see in AB or precisionX is the percentage above what you set!
Ex: with a 500W bios (Slider set to maximum of course) you see 60% usage, this equals to: 500x60%=300W
YOU CAN DIRECTLY CONTROL TDP WITH THE SLIDER! thumb.gif

Now, why has AB a 300% slider while PrecisionX uses 200% for the same bios with the same PT?
Well, AB and precision have different interfaces so the readings are different for the same thing, just keep in mind the base TDP value and make your calculations from there
It doesnt matter what the % slider is in any program, just increase it if you having stutters or frame drops and when making calculations always make them from the base TPD:

aW x b% = cW (a= bios base TDP, b= OSD TDP, c= aproximate power draw)"

AFAIK no! i haven't had any reports besides not being able to do the mod but that is because people post their questions instead of going to the OP to check whats new and/or fixes! rolleyes.gif

If I could get some help that would be great smile.gif. When ever I try to increase the voltage with the tool the voltage slider glitches out and even if I change the power instead the voltage won't increase. Using the tool to disable the llc works fine tongue.gif

I'm curious, my overvolting/LLC tool (Zawarudo's) always resets the voltages upon computer reset/sleep wakeup.

Is there anyway to save it?

No, its the way things are, the only clocks that remain are those set in bios or through AB/precision profiles automatically loaded at startup!
Zawarudo's tool does not keep the voltages upon reboot and there is no way to save it! Even so why do you want to have high voltages at boot with high P states?
It only makes sense in extreme OC LN2/DICE! You can use AB profiles loaded at start up with the voltmod up to 1,300V!

AB beta 18 seems to report different voltages with same settings for me.

Hi all, first of all thanks to all those who created the tools we've used to OC! I'm putting my new WC rig to the test.

So my question is, when using the ncp4206 tool can I set the voltage higher that 1300mv? After I type in 1400 into the tool I go to afterburner and move the power slider so I can click apply but the voltage in afterburner is what gets applied.

I have set everything up properly as I can run at 1.325v solid, but my temps are at about 40c under load so I'd like to push it a bit more.

Hope this isn't a noob question - thanks in advance for the help!

EDIT: Forgot to mention I am running afterburner beta 19 since 18 won't run for me (I'm guessing its expired), I followed the steps in the main thread about the workaround for applying voltages but to no avail. It appears that the voltage set in the tool doesn't have any effect - only the value in AB

I've also tried using RunAsDate and I can get beta 18 to run but I can't unlock the voltages using the softmod llc hack.


Ok, I resolved the issue. Here's what I did if anyone else was stuck here:

download AB Beta 18 & install
create this batch script:

set BEFOREDATE=%date:~%
date 03-15-14
START "" "C:\Program Files (x86)\MSI Afterburner\MSIAfterburner.exe"
ping -n 10 127.0.0.1 > NUL 2>&1
date %BEFOREDATE%

run batch as admin, unlock voltage etc in AB
use the tool to apply voltage as shown in the OP

Passed more than two years. Is there anyone with 1.325V (with WC of course)? Is your card working well? Or died? Anyone?

from what I've seen, 99% of us retired our cards before excessive voltage/heat spikes caused any sort of noticeable damage.

I know for a fact that 2x of my WC titans went to someone who cranked the voltage to 1.4 & has had it there ever since. He's still folding on them today, and folding is really where you'll see cards go pop w/ high voltage / OC.
