i have 2x gtx470. i need reduce my lowest fan speed to %10. because using a custom pwm-dc converter to control my fans.

already edited my bios and flashed. afterburner low fan speed limit still %30. what can i do.

thanks.

yes, it is possible..
Its all on the First site..there u get explained how u do it and what tools u need..
i could make u the bios. But im a little out of time and not @ home for at least 2 days

I have understood the options, but the Fermi BIOS Editor does not support the adjustment of the lower 3D clocks and voltages, and I don't know which fields and to which values to set in nibitor Fermi clocks to achieve this (this being: set the lower 3D clocks and voltages to be the same as the full 3D clocks and voltages to disable all 3D mode voltage/clock switching because it causes graphical glitches)

if you want to help me, here is my GTX 480 BIOS, I want to set all 3D clocks to 840 mhz @ 1.050V

no actually you know what, I want to to also set the 2D clocks to the same 840 Mhz @ 1.050V

thanks !

thanks !

are u shure u want the 2d clocks so high?
i mean wheres teh point in it? u dont save energy, waste heat and what for do u possibly need this power in 2d mode?

U also can do it like me..i made me 2 main profiles with afterburner..
one for desktop, movie, browsing, angrybirds et cetc low perf stuff. And one for gaming..

Profile 1 ---> 400mhz Gpu - 1250mhz Ram @ 0.875 volts.
Profile 2 ---> 880 - 990 Mhz - 2000mhz @ 1.060 - 1.100 volts.

Its only one click for me to change it..it saves power, doesnt make problems with 3d 2d throttle..is still enough perf to play a 1200p Full HD video with an bitrate of 180MB and more..(at 60 fps / hz that is)

Im not saying i wont help you, i just wanna understand why u wanna do that the way u want..

When my comp boots up the gpu is in stock state, though the unlocked bios makes it boost to 1306mhz

anyways i have three .bat files that i enable from start menu

gaming
-forcepstate:0,2 -setpowertarget:0,150 -setMemoryClockOffset:0,0,500 -setGpuClock:0,2,1258(1.2v)

movies
-forcepstate:0,2 -setGpuClock:0,2,854 (at this speed vram goes to full 3d clocks and voltage 1.0v)

browsing
-forcepstate:0,8 (it sets gpu clock at 324mhz) 0.98v)

Just thought i'd share.

that sounds interesting...
got any more info on that?

Well you need inspector, you then make the .bat files in that folder and you then make shortcuts of these .bat files and place them in the start menu.(ready to be selected at click of mouse)
The .bat file usage became a popular method of disabling Kepler boost feature.

nvidiaInspector.exe -forcepstate:0,2 -setpowertarget:0,150 -setMemoryClockOffset:0,0,500 -setGpuClock:0,2,1258

BetA, that's my problem: http://forums.guru3d.com/showthread.php?t=374034
doesn't seem to be any other choice except to completely disable all clock changes in the card, and set it always to highest, if it takes me power so be it, as long as I don't have to be stuck in 2D clocks forever until I reboot the system. I am not concerned of this change because I can always flash the original bios into it again. afterburner and any other software changes to the clocks have no effect.

Changing the default fan settings (40%-85%) .You can change the minimum and maximum "fan speed" that can be controlled with software to the desired values. For example that the fan can ramp up to 100%.

2: Voltage settings.
Here you can change the voltage settings of every P-STAGE

Note: the minimum you can go with FERMI is 0.825V , NiBiToR lets you go lower but it will not work !!!!!!!!!!!!!!!!!!!!

3: Clock & Memory settings.
New: use our FermibiosCalculator , it does it all , it calculates the right values and it shows you where to put them in NiBiToR :http://downloads.guru3d.com/download.php?det=2743

For the clock/shader speed and memory speed we made a real easy to use tool , "FermibiosCalculator" , this tool does all the calculations for you and shows you where to put the values in NiBiToR. We made this tool because NiBiToR doesn't do the calculations for you. Here it is :

Just type in your new shader speed and memory(not needed if you don't change it) and select your GPU , this app will calculate the values (bumped shader )and show you where to put them in NiBiToR in the P12 level and or P15 level depending on what GPU. The tabs that stay blank you DON'T change !!
Supported cards are: GTS450, GTX460SE, GTX460, GTX460 ASUS TOP, GTX470, GTX480, GT520,GTX550ti, GTX560, GTX560ti, GTX570, GTX580, GTX590.(can change)(If you use this please read the "read me" file !!)

CHANGING CLOCKS: (Core and shader are linked with FERMI)

"NiBiToR" (Tools - FERMI Clocks)

When you change the "Shader" speed then the "Bumped shader" speed must be adjusted!!!!!!

There are differences between the Fermi GF100 and GF110 like the pictures shows.

-For the (GF100) GTX465 , 470 , 480 the rule is to put in TAB4 the new calculated "bumped shader" value and in TAB11 the same value as your new SHADER speed!!!!!!!!!!!!!!Also the ASUS GTX460 DirectCU TOP)

-For the (GF110, GF104 , GF114) GTX460 , 570 , 580, 590 and GTX560ti you put in TAB4 and TAB11 the new calculated "bumped shader" value!!!!!!!!!!!!!!!!!!except the ASUS GTX460DirectCU TOP)

ASUS GTX460 DirectCU top is exception on this rule.
Here you see the ASUS GTX460 DirectCU top compared with the MSI Factory overclocked card and a ASUS card at NVIDIA reference speed.
In the Asus GTX460 DirectCU TOP bios the overclocked Shader speed is in Tab 0 , 1 , 3 and 11
Only in tab 4 they put the Bumped shader speed.
(center BIOS = ASUS DirectCU TOP , all bioses are version 70.04.13.00.01 , so it is something ASUS does to this bios with this card)

If you edit the ASUS GTX460 DirectCU TOP bios with "FERMI BIOS EDITOR 1.55" things are adjusted automatic in the way ASUS does in the DirectCU TOP card. Or use the FermibiosCalculator and select GTX460 ASUS Top card.

How to calculate the "bumped shader".Or use the FermbiosCalculator.

I calculated the value that you need to multiply with your new "shader speed" to get the new "bumped shader" value.

Here are the values for each card .

GTX460 = 675/1350/1800MHz = 1431:1350 = 1.06
GTX 465 = 607/1215/1603MHz = 1272:1215 = 1.04691
GTX470 = 607/1215/1674MHz = 1272:1215 = 1.04691
GTX480 = 700/1401/1848MHz = 1472:1401 = 1.05067
GTX570= 732/1464/1900MHz = 1539:1464 = 1.05122
GTX580 = 772/1544/2004MHz = 1620:1544 = 1.04922
GTX590 = 607/1215/1707MHz= 1272:1215 = 1.04691
GTX560ti = 822/1645/2004MHz = 1744:1645 = 1.06018

(NOTE: the calculation of these values are based on the stock bios settings of every card)

The rule : divide stock "bumped shader (tab4)" with stock "shader (tab3)" , the result of this you multiply with your new "shader speed (tab3)" and the result of that is the new "bumped shader speed".

Examples:

1:Changing the clocks on the GTX480 (GF100)

Stock settings on this "factory-occard: "Shader":1512 (tab3 & 11) , "Bumped shader":1590 (tab4) , Memory 1900(tab5)

This card runs at stock "factory-overclock" 756/1512/1900MHz

We are going to change this to 800/1600/2000MHz.

Memory : change the value in tab5 to 2000.

Shader: change value in tab3 & 11 to 1600.

Bumped shader: 1590/1512 = 1.0515873 x 1600 = 1682.53968 = 1682 in tab4

Warning for GTX 460 , 465 , 470 , 480!!!!
Not for GTX 570, 580,590 and GTX560ti.
Or use the FermbiosCalculator it shows this !!

2:Changing the clocks on the GTX570 (GF110)

Stock settings on this "factory-oc card: "Shader":1600 (tab3) , "Bumped shader":1680 (tab4 &11) , Memory 2000(tab5)

This card runs at stock "factory-overclock" 800/1600/2000MHz

We are going to change this to 850/1700/2200MHz.

Memory : change the value in tab5 to 2200.

Shader: change value in tab3 to 1700.

Bumped shader: 1680/1600 = 1.05 x 1700 = 1785 in tab4 & 11
---------------------------------------------------------------------------------------------------------------------------------------------

TIPS:
-I did find that with GTX570 , 580 and GTX560ti that when you put in tab 0 and 1 the same value as the new shader speed (tab3) in the P15 level the overclock was more stable , meaning that "the driver not responding" message didn't appear so fast after a oc.

-When you are on watercooling are other exotic cooling, set the fan speed at 0% (min and max) , I noticed that i can get higher speeds with lower voltage if I do this , I think that when you do this the fan controller on the card is disabled so it don't need no more power.

---------------------------------------------------------------------------------------------------------------------------------------------

Finish every editing with "APPLY" and save your edited bios as a (.rom) file.

ALWAYS REINSTALL THE NVIDIA DRIVER AFTER FLASHING BIOS.

REMOVING POWER-DRAW LIMITER WITH GPU-Z WILL RESULT IN BURNED VRM'S !!!!!! (This is a fact for the GTX570)http://www.overclock.net/nvidia/9291...led-570-a.html
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Some INFO on the GTX590

The GTX590 got a P14 level , this level is the downclock level , when the card got to much powerdraw the card will trotlle down to these clocks.
Core=553MHz / Shader =1107MHz and Memory=1603/3206MHz Effective datarate.
It will use the voltage setting 1 .

You can not see these clocks trottling down , your software will show the default clocks 607/1215/1707MHz. The only thing where you will notice is that your FPS will drop down.

So overclocking this card its hard , you need to find the max voltage before you notice that your FPS in games are dropping down. Better to just try raising the Clock speeds and NO Voltage tweak.

The latest NVIDIA driver won't even allow voltage Tweaking with software.

I think the highest stable clock that you can get without voltage tweak is 680/1360/1850MHz(3400MHz)

This p14 level will be activated by the driver. (Ex: Running Furmark will activate this and some other stress programs)

The GTX590 is a bad overclocker if you want to tweak voltage ,If you put the voltage to high the powerdraw limiter will kick in faster.

My advice on the GTX590 is NO OVERVOLTING!!!!!!!

GTX590 BIOS Screen

Changing the original BIOS and flashing your GPU will void your warranty. ALWAYS MAKE BACKUP OF ORIGINAL BIOS with NVFLASH or GPU-Z.

How to backup your original BIOS and how you flash your NVIDIA gpu is explained here :http://forums.guru3d.com/showthread.php?t=313989

If you have questions about the "FERMI BIOS EDITOR" tool or you want your BIOS to be edited for voltage Maximum and Fan speed "BetA13" is the person to talk to.
You find his thread here :http://forums.guru3d.com/showthread.php?t=329033

DRIVER 280.19:
It seems that the voltage settings on some GTX570's and 580's is up withone step if you use Driver 280.19.
Example if you set in nibitor 1.013V it will read out in software like AIDA64 and MSIAfterburner as 1.025V.

It is only when the bios voltage settings are not the same as the nvidia default bios.
This is what ManuelG had to say about it :

Quick update on the changes in the way the voltages are being reported in GPU utilities. This is not a bug and actually corrects the way the voltage is communicated to 3rd party GPU utilities. The older drivers (pre-R280) had a couple bugs which didn't round the voltages in the Perf and CVB tables to the board values in the SW caches of the Perf and CVB tables. When those values were actually applied to the HW, they were rounded up to the correct board values. The new 280.19 driver fixed that issue to make sure that the code only cached the true board voltages. However, in both cases the values which are applied to the GPU are the same so the only difference is the voltage that is displayed to the user. The actual GPU voltage has not changed from 275.50 to 280.19. We have verified this ourselves

CIVATO 2011 (THX to BetA13 for extra INFO)

No. Its Not possible. A GTX 460 cant be flashed with an gtx560 BIOS...
I mean it can be flashes but it wont work...

unfortunately the problem I had in the 480 also exists in my 580
I am trying to force all clocks and voltages to be fixed at maximum at all times, I would like your opinion before flashing this bios onto the card

there should be two images above, can you see them ?
if you can't, then I will explain.

my nibitor voltages don't show anything in the Setting 0,1,2,3 fields
there is only voltages in the Perfmode / Voltage category, is this an indication of anything ?

I copied the P15 voltage into all the other voltages

then I copied all the clocks from P15 into P7 and P3 exactly as they appear

Hi, I have a very particular request and some doubts, could some please help me?? All is concern about editing Fermi bios´s.

I have an Asus G74SX laptop with GTX 560M 3GB 192 bit version, which I use for Hackintosh (install MacOS X on no Apple Hardware), so all it´s working right my only problem is some desktop animation lag, this is caused because this as many other GF 11X Fermi only has 3 Pstates, but apple´s power management drivers waits for 4 Pstates. My Desktop GTX460 has all 4 Pstates and no lag at all.

I found a VBios from other laptop (MSI GT683r) with the same GPU GTX 560M 192 bit version but has only 1536 MB of RAM. This Bios has 4 Pstates on it!!!

Can I use this BIOS with less ram??, the amount of VRAM can be edited?? Can someone help me to enable 4 Pstates on my VBIOS?

My VBIOS http://www.techpowerup.com/vgabios/1...72.110504.html

MSI VBIOS
