nVIDIA mobile Kepler 6xx MASTER overclocking guide. Workaround for max clocks/OC stability.

I think the difference isn't that much right now. However, Nvidia is really likely to release their new drivers every time a big title on sell for improving game performance; the gap will become more serious eventually.
I have tried to contract the developer but it seems he has stopped his work for a long time. I have no idea who am I supposed to report this struggle now. Hopefully, somebody will manage to fix it soon.

 

Surprise! The unlocked BIOS is available! For Windows 7 bios is ready. Ask author for Windows 8 uefis.

 

Quick little run on the GTX 670MX. Not maxed out and that was the first 3DMark 11 I ran.

100% stable temps under furmark are 76c

 

Nice numbers man, didn't know the 670mx could bench that high :thumbsup:

 

That's what I run it at that 24/7

 

WOW! This is surprisingly incredible!! I love you James D and thanks very much to Prema. I would definitely miss this bios if you did not inform me about its availability.
Currently, I have tried overclocked @1110mhz with the lastest driver and it works like a charm. Now I'm looking forward for further overclocked speed, may be overvolting? Any suggestions would be really appreciated .

 

Drivers are not the best. Going to try some others i should be able to gain a few more points out of the system. No volt mod or anything yet totally stable running furmark so looks like its a nice card and very nice memory on it.

James D, is this for the barebone version of the GE60 too?

 

I have a G75VW with 660M. Can somebody help with this new bios thing for the Asus side ? Really appreciate it.

 

T|I has the unlocked Clevo 660M (and maybe OVed) BIOS which can be flashed to the G75VW's 660M to unlock it

 

My temps are just as high on my n56vz. I am considering using a cooler or repaste. Maybe add some extra cooling.

 

I did not get that. What are you saying I can do ?

 

You can flash a custom unlocked vBIOS so you don't have to use the NVinspector method to go past +135MHz

hi guys,

ive just purchased and originpc eon 17slx which i think is a sager 9370 equivalent i think. I opted for the option of overclocking from them. I spoke to them and was told that they would perform a "safe" overclock which should see upto 10% performance benefit. They also mentioned that they vbios would then be unlocked if i wished to further overclock it. Am i to assume that they will be doing the flash outlined in this thread?

 

Don't order the bullshiet OC option, they won't flash a vBIOS for you either.

You should buy from xotic instead, it's cheaper (by far)



N4/5/76VZ owners, currently we do not have a dis assembly guide. Repasting might be unavailable, and using a cooler pad does not affect the IVB N-series at all

 

Thanks for the update, I will be monitoring this thread.

 

As I know MSI warns that nobody used whitelist BIOSes for OEM MSI laptop and vice versa. Prema did 4 BIOSes but 2 of them (Win8 version for GE70 and GE60) are hied now because he needs to work with them more.
If someone needs for barebones he may ask Prema and give him a link BUT I have no idea if he has free time. He is busy man.

Overvolting is smth that Prema can't do now. He hasn't this laptop so he needs a looong chat with svl7 to create a working BIOS with overvolting.

 

I can't download the flash tool mentioned in this post. [G75VW] - modified BIOS & VBIOS for higher overclocking I need to be registered and have at least 5 posts to download. Can somebody that already has an account in that forum pass me directly the download link ? I would realy appreciate it. ex:depositefiles

 

Alright, I will update the 1st post later to link the GE60's unlocked BIOS and not to crossflash between barebones/OEM

PM me as a reminder

Looks like i will meet my goal of matching the stock GTX 680m performance with no volt mod. Yeah i know a GTX 680m will still slap this card and overclocking it just makes it hurt more but still for a $1250 system cranking out the performance of a GTX 680m is impressive.

Has anybody overclocked using this tool? Apparently it's a BIOS tweaker that works for all Kepler chips and gives you a ton of customization in regards to clocks, voltage, fan, power management, etc. You then flash your modded BIOS using NVFlash or similar.

I'm basically clueless when it comes to flashing so I haven't attempted this yet, but it seems like a better method of overclocking than using Inspector and .bat files. Plus, you can use any OC tool you want and maybe push the card even farther if the voltage is adjustable.

 

Yes it is, but you risk bricking your vBIOS if you make any wrong adjustments. But from what I see, if you can extract your bios, the tool looks very safe.

If you decide to try it, please post back with results

 

I tried it out just now, but can't get it to work. Maybe I'm just not getting it, but somebody on Tech Inferno mentioned that it doesn't work for mobile BIOS, at least not Kepler, and everything has to be via Hex Editor for now.

 

Sorry to hear that. But maybe if you send them your vBIOS they can work on it.

 

Yeah that's what I plan on doing next.

 

Hello, my laptop is ASUS N56VZ with GT650M DDR3 version and I've been getting this weird throttling (is it really throttling?) where my clocks goes from 900mhz all the way down to 135mhz for 1-3seconds and goes back up and then down again... FOREVER!

I tried nvidia inspector, it does help abit by downclocking GPU clock to 630mhz so that it doesn't hit 70C but for some reason now it does throttling at 62C. CPU has no relation to this issue. ThrottleStop has no effect.

I cleaned my laptop vents more than once but with no real changes. Back then it used to stay at 70C without dropping all the way down below idling speed. This issue occurred when I formatted Windows using [Refresh my PC].

-Changing to max performance on nvidia control panel, no effect.
-Updating BIOS (says new vBIOS on asus support website), no effect.
-Cooling pads, no effect.

 

I have a Quadro K3000M and as soon as my power lead is removed the performance of the GPU is limited to around 20-30%.

Is there anything I can do to stop it?


My GPU performance is shocking on battery, gpu z tells me the clock speed drops to 135mhz on battery. Everything inside the Nvidia control panel is set to max.

Plug power back in and it's back to 654mhz?

On Mains Power



Just by removing Mains lead



No matter what driver I use always reverts to the lower speed on battery, also tried my backup Windows 7 OS

 

I would check your power profiles and see if changing the graphics settings in them see if that helps? I never checked my clocks when gaming on the battery but mine would probably drop to that as well.

 

Yeah I have gone through every setting, as soon as the power lead is removed even in Windows the clock speed is 135mhz and wont increase no matter what I do. OC etc

 

Throttling on battery is unavoidable on high-powered mobile Nvidia GPU's. Even if you tried to force the highest P-state by modding the vBIOS you'll never be able to achieve max clocks and voltage because your battery alone can't supply enough power and there's probably a hardware failsafe in place to prevent you from killing the battery through sudden rapid discharges.

 

Hello everyone. Awesome thread you have going! I love being able to tweak laptops to gain more performance for the hard-spent cash.

I've got some big questions that hopefully you guys can answer. So I just purchased a lenovo Y400 laptop with the i7 and gt 650m gpu (ddr 5 I believe). So based on this thread, it looks like I may be able to overclock it significantly. However, I'm confused on what to expect from it. What sort of performance increase can you get from an average overclock of this gpu? Like 20% increase? Frankly, I'm wondering if overclocking this gpu (especially with a more 'tolerable' unit) might really reduce the performance difference in a Y400/500 with the SLI dual graphics option, which is said to give a 50% performance increase.

What do you guys think?

 

You might want to look at this thread

See what clocks and synthetic/real performance increase you might be able to get.

Not games, Video Editing

 

Well, based on the 3dmark scores I'm seeing, it looks like I could expect about a 25-30% increase in gpu performance? Does that sound right? I'm more familiar with overclocking CPUs, and I know that eventually increasing the clock has diminishing returns. Not sure if it's the same for a gpu or not.

If you were to have this in sli configuration, could you concievable overclock both GPUs, and see something on the order of twice the performance you'd get over one, normal clock 650m?

 

Hey guys
I have a Lenovo Y500, which is running a core i7-3630QM and a gt650M graphics card. I recently tried overclocking the 650m using both Nvidia Inspector and MSI Afterburner, but the clock speed never changes. I can however, change the memory speed, although I suspect this is a false reading because performance does not increase even a bit. Am I doing something wrong? Is there a BIOS patch I have to apply to change the card's speeds? All help is appreciated. Thanks.

 

Yeah 20-30% increase on a single GPU seems to be the ceiling, but you would need a significant overclock for that and not every card can pull it off. As long as your GPU doesn't overheat, artifact, or crash then you should be good. Law of diminishing returns applies to any form of overclocking be it GPU, CPU, RAM. You're gonna reach a point where a small additional increase is not worth the tradeoffs in system stability, noise, heat, and power consumption.

SLI performance is always dependent on the application and how well it scales in that particular situation. SLI GT 650M has up to 90% scaling in some games so it is definitely possible to achieve twice the performance of a single 650M at stock if you overclock. Look at some of the 3DMark 11 scores in this thread. Some people who overclocked in SLI had more than twice the Graphics Score of a single GPU at stock.

 

Is there a tutorial on how to mod my own BIOS? Or is there one available for Lenovo Y500. I have a GT650M GDRR5. I have experience with 500M series

 

There is a modded Y400/Y500 BIOS made by svl7 who is also a member on these forums. It is located here on the Tech Inferno Forums and you need to have at least 5 posts to download the files. Follow the instructions in svl7's first post to the letter or you may brick your computer.

This BIOS mod is mainly for removing the hardware whitelist so that you can install different WiFi cards. It also unlocks a bunch of other advanced options that were hidden in the stock BIOS. There are a few that are somewhat useful like being able to disable C-states and changing the CPU thermal configuration but I would caution against messing with anything you don't understand. Some of the settings, such as those related to the integrated Intel GPU, don't do anything.

This mod does not allow the Intel GPU or Optimus to work as that is a hardware issue. It does not allow you to overclock the GPU and the Nvidia Inspector method is the only working method so far for the Y400/Y500 since nobody has yet modded an overclocking/overvolting BIOS for this machine.

If you are interested in this BIOS mod make sure you check what BIOS version your Y500 has and flash the correct mod for that version. So far, only v1.03 and v1.05 have been modded. Don't flash stock v1.03 with modded v1.05 or vice-versa and I don't need to remind you what might happen if you did.

BIOS revisions later than 1.05 have not been modded yet so you are out of luck if this applies to you. Somebody with 1.07 did report success with flashing the 1.05 mod but I personally wouldn't risk it. My first Y500, which was returned due to defects, was 1.05 and I was able to flash successfully . The replacement unit is 2.02 and since I don't plan on installing a different WiFi card having a mod for this version isn't urgent.

 

Any workaround for 313+ drivers limiting core overclocking? I'm on a VAIO S13 and previously I could clock up to 900mhz with the bios mod I picked, but now core is limited with the drivers later than 310.90 mo matter what I do. Memory is still freely adjustable

 

S13 has a 1GHz OC BIOS

Try find it in the forums somewhere, it's here but I forgot where it is.

 

I think you're misunderstanding. The OC bios only work with 310.90 and below. And driver version beyond that limits the core clock to stock plus 135mhz (using NVIDIA inspector) no matter what the BIOS. There is something in the newer drivers limiting the core clock no matter which modded BIOS is used

 

Are you sure about that? I thought an unlocked BIOS removes the artificial +135 MHz limit regardless of drivers and will allow you to use tools like MSI Afterburner to OC. You're sure the limit you're hitting on drivers later than 310.90 isn't due to Nvidia Inspector needing an update?

 

I've a question!

I have an Inspiron 7720 (with a 650m), and was thinking about overclocking it... the guide on the first page seems pretty complicated, but I tried EVGA Precision and it seems to overclock the card okay... is there anything bad about me using this program? Or do I have to use nVidia inspector for something?

edit: Ah, nVidia inspector was easier than I thought I thought I'd have to mess with settings and flash bioses and stuff like that, or am I missing something?

 

Did you go past 135MHz?

 

I ended up using nVidia inspector, and so far added +100 mhz to the core and memory in the 'gaming' state... does something happen after 135 mhz?

 

All drivers have always implemented that limit, that's the point of the BIOS tweaks. Can you shoot be a link on the 310.90+ drivers overriding the BIOS?

 

If you're on a driver lower than 310.90, OCing past 135MHz is possible (which is the entire point of the thread)
