Actual voltage wont start changing until you go +150 or higher. I think inspector doesn't see that 1.012 is the stock max correctly.

Are u using an unlocked bios on ur GT70?

strange thing is it doesn't crash the driver. it just wont go above 993. all benchmark tests run ok and don't crash.

does the 780m vbios overclock edition posted on page 2 work on any 780m. I have MSI GT70 dragon edition 2. Thanks.

have you tried to increase power and thermal limits ? are you using inspector or afterburner?

Probably driver signing was disabled cmd admin type "bcdedit /enum" look for windows boot loader results, better to leave F8 safe boot option enabled.

the bootmenupolicy was set to standard

For drivers, extract 7-Zip (v9.25 x64) NVIDIA DRIVERS 320.49WHQL Intrnational folder>delete GFExperience / MS.NET folders>copy/paste NVWMI folder from MSI 311.70 driver / International folder.

Use first nvcvn.inf http://forum.techinferno.com/attachments/general-notebook-discussions/8109d1372827532-nvcvn.inf_msi_gt702od_gtx780m_v320.49.zip then try with NVMIn.inf http://forum.techinferno.com/attachments/general-notebook-discussions/8111d1372840127-nvmin.inf_msi_gt702od_gtx780m_v320.49.zip

Disable driver signing and enable F8 safe boot option. Command prompt(admin) then reboot.

bcdedit /set {default} bootmenupolicy legacy

bcdedit -set loadoptions DDISABLE_INTEGRITY_CHECKS

bcdedit -set TESTSIGNING ON

Exit safe mode / normal boot

bcdedit /deletevalue loadoptions

bcdedit -set TESTSIGNING OFF

bcdedit /set {default} bootmenupolicy standard

@CACV , @dttran83 , could one of you guys test if the voltage changes when u increase it?

are any of you able to increase voltage ? also @dttran83 is it completely stable? because when i ran at those clocks the card didn't even run 3dmark 11 or complete a 3dmark11 test

^^^ k thank, do you still need do that sign off mode to install the driver?

I will try your solution killer!, regards!

The entries for the 119F.10EA.1462 will need to be changed to 119F.05AA.1462 for the 311.70 drivers to work on the modded ROM

the modded ROM works on the MSI cards , it is most likely a limitation in the bios that we can't increase voltage

the BSOD are caused by driver incompatibilities most likely due to the NOS system since no other laptop companies is using this technology

yea you can change it in your overclocking utility or it might just be downclocking due to power restrictions but it take alot into consideration when it starts to downclock

Hey svl7,

Will the gtx 780m vbios prevented it from down clock? My card start to downclock from 980mhz to 967mhz at around 84c. I have a MSI gt60-20D. Thank!

thats due to the dynamic system, maybe u have the temp target set to 85 or something similiar?

Did you use the Nvidia Inspector?

Also you could try it without the MSI software installed, i.e. without that nos crap etc.

sadly enough the NOS system is built into the laptop itself , yea i was primarily using inspector , i posted the MSI vbios in this thread , but u have been working on a MSI vbios so it has to be the MSI laptop , but in all seriousness the card is great even without the increase power .

I'm using an MSI card and 320.49 is doing well. Might be your system.

Yes, the throttling will be gone, unless your temperatures are way too high. Just use the modified version of your bios, whether you want more voltage or not is up to you to decided. The turbo button will loose it's functionality with the modified vbios, I removed that since it's pointless with the mod vbios.

ya , I think its the MSI system itself .... the 311.70 from MSI work so , well the 320.49 do work well except it bugs out sometimes when switching from igpu to dgpu but thats all, also the 780M OC vbios on MSI GPU with the MSI laptop doesn't allow the voltage to go above 1.012 , which i believe is the default max voltage if i am not wrong. it might just be that the NOS system they created might have a fixed voltage set for the Card on MB ... maybe i hope i am wrong

thanks for help , but it seems that any drivers that don't support the msi version cause a driver_power_state_failure BSOD ... so i went back to 311.70 from msi

yep i did disable driver signing however using a different method since the smart boot doesn't allow the cmd prompt method for some reason , i did windows_key+I>change settings> general> scroll down to bottom and click on restart now under advanced startup> then select advanced options> advance startup then f7 for disable driver signing , i wish i could use the cmd prompt method , this one such a hassle, however there is one bug , when the screen turns off or something like that it freezes but aslong as the computer is being used it perfectly fine, also this bug is related to the driver not the vbios

IDs PCI\VEN_10DE&DEV_119F&SUBSYS_05AA1462 ?

yea same ID , the driver installed however it just didnt go into windows :\ i also tried modding 326.01 mineself and it caused a bluescreen so im not sure what went wrong

With dynamic action going on, you might not see a change if the GPU is not under load. Did you load the card to see if it made a change, or are you relying on what you see when idle? If I understand how it works (which I may not, LOL) you are using an offset that raises a peak limit (ceiling) and not directly adjusting the static amount. Your Haswell CPU should also have power offsets that work in a similar manner if you have an unlocked sBIOS or if your system is XTU 4.1 compatible. Those are design to allow a higher maximum only when demand exhausts the normal amount of power available.

yea i was running 3dmark 11 but it would just lock it to 1.012 V which is the default max voltage so when i was trying to push the 1ghz core it would simply cause the 3dmark to error saying the DX11_Removed or something similar, im starting to think its either that im using NOS+180W to its limit but wouldn't the laptop shutdown if i was pushing it further than that or MSI has voltage lock on the EC or somewhere where it shuts down the device... i have attached the MSI vbios just incase svl7 would like to look at it but im thinking there might be a limit on to voltage somewhere else but i most likely am wrong

OGTX780M.zip

Well i installed the vbios which installed perfectly fine and then tried to do @J95 suggested however it it wouldnt boot windows so i uninstalled and then installed the laptopvideo2go inf for the 320.20 drivers for the 320.49 drivers and that worked out, also when i set it to +25 mV it wouldn't increase the voltage to that amount

will the GTX 780M vbios should work fine in all 780M cards? or is there only a specific one since the MSI do have different memory modules ?

also forgot to say, great job guys and thank you

has anyone looked this yet ?, it is for primarily desktop cards but it seems interesting:

KGB - Kepler BIOS Editor/Unlocker

i had this issue before, what i did was remove the rubber foot on the bottom and put another screw in the same hole and screwed it in and then the broken part should be visible on the other side and i got a piler and kept rotating the broken part till it past all the way thru.

Hello,

I am wondering if it is possible to repair a GPU card bios chip copper plate locations, it should be more clear of what i Mean in the picture

any help is appreciated

But, it should not go down below reference voltage under load. Sorry, I think I misunderstood what was being said. Those higher voltage values are not the normal operating voltage for the 3D state. So, as I would see it, it is not a "voltage drop" as much as it is the voltage returning to normal after a spike. I thought there was someone having a problem with a power throttle or a condition where voltage was dipping below what it should be in the max 3D P-state.

Once my GPUs enter a performance state the voltage remains steady and does not fluctuate while it is under load. It might do something like that with a stock vBIOS, but I don't use a stock one and never bothered to check.

You will not see voltage "drops" under load in either video...

Even with this old outdated vBIOS it does not fluctuate... pardon the low score. ...was an old vBIOS.

interesting, could you provide a HWinfo log showing from idle clocks voltage to full 3d clocks voltage

EDIT: sorry i would do this test on my own GTX 680M but it currently has a broken vbios, I'm still waiting for the programmer to get here :\

I fully understand this safe voltages. My stock voltage is 1.0120(With Stock BIOS, as I remember). So why under 100% GPU load voltage is 1.0120 insted of 1.05. I saw only 1.05 when 3DMark was loading.

Edit: May be slv7 changed power-save voltage insted of 100% use voltage

Edit2: Made another test in Medal of Honor Warfighter. While i was in menu voltage was 1.05. When game started voltage is 1.0120.

if u open up MSI kombuster or any 3d stressing program you will see the voltage jump to 1.05 then after awhile it will drop to 1.012, this even happens on my GTX 485M.

EDIT: well when I said my GTX 485M , i meant it's respective voltages

It is normal to drop voltage, core and memory clocks if the demand does not require use of the resources. That's not a feature if it is doing it even when it is not supposed to (i.e. under load).

its more power savings, for full 3d clocks , like for stock clocks it goes to .987 then drops down to .962 , i believe , they only reason why the have upper voltage is to safely transit from going from 135 or 450 mhz to 716 or whater your clocks are set at, then after it detects that card doesn't have any faults occurring or issues then it drops down to the lower voltage. your card should show the same behavior i believe, my card did. so that is why it goes from 1.050 then drops to 1.020. well it seems like sv7 increase the drop voltage, i think however it is still completely normal thing to happen also discussed earlier in the thread.

all GTX 680M have two seperate 3d voltages, one is the transient 3d voltage to initialize the clocks speeds and the other is takes over after the initial boost to maintain the clocks.

so this one has .987 and then goes to .962 , also another is the the 1.05 volt which goes to 1.037
