[UPDATED AB B18] Team Skyn3t's Unlocked NCP4206 Voltage / LLC mod tool - Page 109

post #1081 of 1362
I assume having 1.21v voltage unlocked is not a good idea for those who use air cooling? Right now my card does 1280 / 7400 on air using unlocked 1.21v ASUS GTX 770 BIOS, which I unlocked myself with KeplerBIOSTweaker. I only want to know how to edit my BIOS further to completely remove any Boost feature. From what I see from your BIOS is that you set TDP Base = 3D Base = Boost. Would that insure that Boost is not used? I want there to be only 2 possible speeds for my GPU - base clock of 1046Mhz and OC clock of 1280Mhz. There should be no fluctuations in GPU clocks between those two speeds. How can i make it happen? I am sorry if this is off-topic...

Works great for me mate.......Thanks!

Windows 7 Ult. 64 and no hitches at all..... Haven't done anything with it yet as I have been to busy, but I just wanted to see if it would change and it does.

here this should be a better pic. how come it is so horrible when uploading??

Have you enabled "run as administrator" on both AB beta 19 and the voltage tool? is your anti-virus blocking any of them ?

Our bios are modded through HEX tools, not by KBT! its a nice tool for simple things but its not a complete editing tool as you know!
I gave you a link to our modded bios for the GTX770 earlier or you can try your luck with KBT, your choice!

  • All V-Bioses have a base clock of 1150Mhz
  • Voltage is set to 1.212v unlocked
  • Default power target is 100% 300W to 150% slide 450W
  • Boost is disabled with this feature you should achieve a better OC and high core clock. for some users it may be making much difference because each GPU Chip has they own potential OC capability it does apply to any GPU class, and brand.

For flashing you have EZ3flash in my SIG and my guide about it!
Our tool is designed for the voltage controller NCP4206 with the Titan/780 PWM in mind, i cannot tell you if it works with your card, i have seen GTX770 working with it, but you have to test it at your own will and risk to find out if it works with your card!
You have my volt mod guide in my SIG but here it is: OCCAMRAZOR VOLTMOD / LLC GUIDE

You have my volt mod in my SIG

When I download the Zip folder from your sig, I am u able to unzip it. I get an error saying the folder is empty.

Use winrar or winzip, the windows zip functionality is broken for some type of files! thumb.gif

My only question regarding the 770 BIOS is that Power is set to 300-400W! Would that not kill my card, being on air cooling and all?

Read my articles 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 doesn't 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 with my formula:

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


"IMO, The way LLC works makes some cards crash because the VRM's cannot cope with the sustained

power without variation as its harder for them to sustain it! the overshoot with LLC at 100% (ON

technologies, makers of the NCP4206/8 voltage controller labeled it at 0% but its really 100%) is

actually higher than with LLC at default!
Voltage is not to worry about but the amperage drawn by the voltage increase, you can limit the TDP at

a "safe" level (depends on the card) with the AB slider (thus limiting the amperage), make the

necessary calculations with my formula to find the maximum drawn wattage:

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

Then convert it to Amps:

The current I in amps (A) is equal to the power P in watts (W), divided by the voltage V in volts (V):

I(A) = P(W) / V(V)

Knowing that: 6 Phase VRM´s (CORE) 60A each = 360A

The only voltage you can control is the core, so:

DC-DC = I(A) × V(V) = P(W) =» 360A x 1.6v = 576W Theoretical MAX Wattage for the core

Lets think "safe" but at the same time not restraining the chip: 360A x 80% = 288A

Amps to Watts:

The power P in watts (W) is equal to the current I in amps (A), times the voltage V in volts (V):
I(A) × V(V) = P(W)

288A x 1,20V = 245.6W
288A x 1.30V = 374.4W
288A x 1.40V = 403.2W

You can go lower depending on the cards needs! As every card is different in power draw you have to

fiddle with it to find your best "safe" limit!"



While these articles reflect the GK110 chip you can adapt the knowledge for the GK104 too! thumb.gif

Does this work with AB BETA 19?

for some reason after doing the CMD hack it just launches the AB Program.confused.gif

IF your cards are the classifieds as you have in your SIG, no it doesnt work! This is for reference cards with the voltage controller NCP4206, your classifieds have the CHIL 8318



For voltage control you have the Classified voltage tool!
