NVIDIA Maxwell VBIOS mods - 900m series overclocking versions

Recommended Posts

Ok so I finally flashed the card so, like I read on this thread before, it came with a clock of 1200 (no boost) and +500(x2) on the memory.

So I started Witcher 3 and it was a no go.It froze and sent me back to desktop.

So I ended up setting a profile in AB with a -300 on mem and +50 on core.Temp pretty high 85/87 but I have 30 degrees celsius in house. Before with default bios I had about the same.When I have the AC on and my room temp drops to 25 then I have like 77-80 max on gpu.

IN nvidia inspector I can move all the sliders except the power & temp target which is grayed out.

I will try to cut less on my meromy and bump another +50(1300 total) on my gpu without any mV added.

And MSI After Burner is still locked for voltage power limit, ad temp limit .Anybody know why?

With mobile NVIDIA cards, MSI Afterburner can adjust only the core and memory clock. For voltage adjustment use NVIDIA Inspector or ASUS GPU Tweak or EVGA Precision.

Run any games only with AC adapter.

having trouble flashing, mnvflash just gets stuck on trying to detect the GPU?

Please i had asked before, but i will try again. I have a alienware 17 ranger and i got stucked in detect the gpu with mnvflash. There is a solution for this? I am using windows 8.1!

i believe the version linked in the OP is incompatible as I have tried mnvflash and 2-3 versions of nvflash with all of them getting stuck on listing the GPU or trying to flash it and the result is the cmd window locks up and i am unable to close it.

in the end i got lucky and found a version that worked linked below:

https://biosmods.wordpress.com/mxm-vbios/

click on the 'THIS' link to download the nvflash.

To use it to help with the throttle on Alienware, please take a look

HERE and use THIS NVFLASH!

this version was automated but worked for me at least. I now have my 980M with svl7's vbios running in dedicated mode.

Thanks!!!

I used my m15x to flash svl7 vbios and used in dedicated mode in alienware 17, i need only work to remove throtling when overclocking, when i have more time i will follow the steps on post that you showed me.

Now i have it in M15x and is working very well playing gta V and crysis 3 with 920xm and 330w psu.

In m15x with svl7 bios got 13550 pgpu 3d11 and in alienware 17 13250!

Ok, so I use NInspector now.I wonder how much voltage do I need to run the card at default unlocked bios 1200/6000 ?

I guess I will start by adding +25mv each step.

you may hit a power limit because of your PSU, if it's a 180W then forget it you won't ever get power you need, if it's about 230-240W then you can adjust a little.

Well my adapter is this one adp-230eb t a 230W adapter link :Products - AC/DC Adapters - Delta Group

In the end the unlocked bios did nothing for me(I could only add max 25mv but still not stable).I flashed back the stock bios, went to NVInspector and I can modify the voltage just like the unlocked one? What's up with that?

Now I keep my card +135mhz and +200(x2) on mem.

These are almost the exact max settings that I achieved with the unlocked bios.

probably cos of the lack of any decent cooling system or just the luck of the draw when it comes to chips....though I probably wouldn't suggest overclocking a BGA GPU anyway.

I understand and I'm happy with my laptop from asus, but next time I will buy a sager laptop.

i would just leave your GPU with the unlocked vbios and keep the stock speeds...if there's a speed increase.

The unlocked bios did nothing for me, except having default clocks 1200/6000 and that's it.Plus it can't go more than 1250-1300 stable with or without adding voltage.

With the stock bios I can also modify the voltage.

At 700 more euros I should have gone with a sager 970m sli and a hole lot better CPU.

Hello guys.

I'm searching for some answers to update myself lol. Is the past when I wanted to make my gpu overclock permanent, without relying on software I mean, I had to extract the oprom module from the main bios, edit it, replace the module and reflash the main bios. On the other side with mxm gpus we could just threat it like a normal desktop gpu and use nvflash. I'm certain this is all familiar with many of you.

It has been a long time since I have looked at laptops for myself and I'm particularity interested on the"new" g751jy with g-sync, I'm trying to really figure out if the difference relies only on some license inside the bios / vbios not.

What I'm finding hard to understand while leaning all of this uefi bios voodoo is if the process of getting the vbios remains the same. If the gpu is "mxm" I presume nothing has changed. You have a vbios eeprom that you can read and write normally. ( correct me if I'm wrong ).

I would really like to hear from all of you that are familiar with nowadays reading and writing vbios process.

I'm really asking all of this because the g751jy 980m is not mxm has you know but it definitely can be flashed since serbicu has done it already and it really seams like the typical mxm ways of flashing on my time some years ago lol ... Does it have a eeprom just for the gpu onboard or is there something new regarding the way these uefi bios work ??

I hope I made it clear :S

Thank you

This might be a noob thing to ask - but is it safe to flash the card?

I've heard (and I'm not sure if these are rumors) that doing a flash can render your card a brick..

I'm in a bit of a conundrum here - as I have the throttle issues with my new GTX 980m, but I don't really want to risk anything breaking XD

it's safe if you know what you're doing and have experience. if you're not comfortable in flashing the card then don't do it.

if you really want to flash the card then you better read up.

Seems I won't have to any more - I downloaded the drivers from here: Index of /support/drivers/upgradeyourlaptop/Alienware

Fairly new drivers for my GPU, and no throttling.

Though I would like to know how the mod the drivers to work?

What? Flashing the GPU and drivers are separate things.

I thought the reason people were doing flashes, was to prevent this throttling issue? Or is there another reason?

people flash roms to overclock, you can still get throttled even though you have overclocked.

Hi, I'm new here, and I have a problem, can anyone help me? I just bought an ASUS laptop, it's G551JM, with GTX 960M and I7 4720HQ, so far everything works fine, except one thing: the GPU gets thermal throttling at 74 degrees, which is low as hell for a gaming laptop. I've been googling for many days now and I found out it's because of the vBios, so I have to mod the vBios, I've followed this guide but I have a problem with NVFlash (I got a modified version too that bypasses certification), it keeps saying "No NVIDIA display adapters found". Is there any NVFlash version that supports GTX 960M? Or am I doing something wrong here? Any help is appreciated. Thanks.

Hmmm...at stock clocks I can't get the 980M to benchmark with the heaven benchmark, it just crashes after a few minutes with the svl7 vbios. Any heavy oc I do causes the pc to restart into optimus mode.

Can't tell if there's not enough juice or if I have damaged the GPU.

Have you only just now flashed & tested svl7's vBIOS, or have you been using it a few weeks? I've read that some people find that stock clocks on svl7's 980M vBIOS can be unstable, this is because it runs the card at max boost clocks all the time, and some cards can't sustain that at the stock voltage of the svl7 vBIOS. You might have to just increase the voltage by a notch or two to get it stable (without adding an overclock). Did you compare your measured voltages (using GPUz for example) between your stock vBIOS and svl7's vBIOS, could be that your stock vBIOS uses a bit more voltage when the card is at max boost?

Yeah that is what I am thinking. I have been using it for a few weeks now, even testing prema's vbios mod as it has a slightly higher voltage but stock clocks.

hmmm....prema's mod keeps resetting the GPU temp target :(

EDIT: looks like I can only do about 1230MHz on the core with a voltage boost of 62mv.

Yeah, that's not a massive overclock, but it's still 100Mhz faster than the stock boost of 1126Mhz, and those 980M's are already clocked pretty high at stock. I don't think many people are gaming at much more than 1300 odd Mhz anway, so you're probably only 100Mhz off what some people are gaming at. 100Mhz increase in clock speed up from your 1230Mhz clock is only a very small increase in performance anyway (max 8% performance improvement).

      Following the release of NVIDIAs new 436.02 driver which I mentioned in an earlier article here, I've decided to make a quick and dirty video showing off NVIDIAs new Sharpen filter which is part of their Game Filter feature. It works with the most popular APIs including DX 9, 11, 12 and Vulkan and can be set on a per-game basis with granular settings of 0-100 unlike AMDs RIS which is limited to Navi and lacks DX 11 support.

      Well everyone...I have a confession to make-I flashed svl7 modified 970m vbios before I wiped my drivers! Everything seemed to run fine, I could game but noticed my clocks fluctuating a bit crazy. Figured I'd try a OC profile in afterburner while running a 27 27 26 26 clock in TS a bit stupid I know. Well 3d mark froze so I did a reboot...Black Screen on startup I heard windows boot so I feared I bricked my card. Tried external monitor..works fine. This is where my stupidity really hit the cosmos. I had another m15x 900p LCD laying around plugged that in. Worked fine back too overclocking bro! Well same thing happened. My profile was not overly crazy as I can remember. But I bricked another screen. Plugged in external monitor everything fine. I was using latest nvidia drivers 436.48 I believe. So I wiped drivers using DDU. Reflashed to stock clevo bios. Tried both LCD again still nothing. Installed old 7970m still nothing. Cleared CMos again nope. Reinstalled 970m with svl7 vbios with newest driver and been gaming on my external monitor. Have done some OC with inspector. Everything seems to work as it should. Temps and performance are great. Did I brick my monitors??? Never heard of this problem.
