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

I can confirm this works on a Lenovo Y580 using Nvidia Inspector and a .bat file pointing to nvidiainspector with the nvidiaInspector.exe -forcepstate:0,5
The Trick is, you have to install Lenovo's Energy Management software and enable Dynamic Graphics Mode before any of the changes to P5 Will take effect.
I Have my 660m set at 1100 Core/2600 Mem. If you set it to any other Power plan it seems to Not want to use the boost technology.

Thanks Everyone and especially you Mobius 1

 

No problem

Glad to hear that it works on a Y580, I will post your guide in the OP

No no, what bios brand do you have?

My asus uses an AMI BIOS (american megatrends)

 

Mobius 1,

I have a quick question for you.

Will anyone of the Vbios work on the first page of this thread for a 660M in a Asus G55?

I'm slowly doing some testing right now finding the max core clock. I'm at 1175 and ran 20 minutes furmark at 69c. I just want to know if I will have the option to up the voltage a little.

Thanks!

 

The vBIOS of the 660m in the G55 is tied to the system BIOS much like the Y580 because it does not use an MXM interface.

There is a v209 BIOS available in Tech Inferno that is unlocked, you might want to ask svl7 if he can up the volts

 

Figures, Asus trying to ruin my fun as usual. Kind sucks that it doesn't use MXM. Ruined the chances of upgrading to a better card lol.

I downloaded the v209 from Inferno, didn't flash it because I had a feeling the volts would be the same. I'll send him a PM and see if he can, maybe a little donation for some persuasion and he will hook me up lol.

Thanks you for the response Mobius

 

Hey guys, in particular Mobius 1

This is just a curiosity post. After testing the OCed DDR3 GT 650M on my Asus N56VZ ( haven't used this guide yet, still the locked +135MHz), I got pretty weird results.

During benching, the max stable OC (1085MHz core | 1075MHz memory) got me regular ~P2660 (+- 5) on 3DMark11, up from ~P2350 at stock. In Unigine Heaven it was even bigger, going from 17.3 FPS (437 score) to 27.0 FPS (679 score) at medium settings. Temperatures remained fairly identical - 3DMark11 registered about 74ºC max for the GPU and 84ºC max for the CPU (although I have lowered these a lot, down to about 72 - 77, by just building a makeshift suspension "gadget" to improve airflow).

But here's the catch. I ran these tests with most of the computer optimized. Shut down unrelated background programs, unplugged my 2nd display, switched to High Performance (Asus', P4G), etc. Just trying to draw that extra bit of power, don't even know what and if it helped. Two or three weeks have gone by since the benching (3 months overall since I bought the laptop).

That's where it got weird, cause a couple days ago I just decided to randomly run a 3Dmark11 bench. I didn't close anything, I had the dual monitor set up, left the power option at 'Entertainment' (again, Asus' P4G), didn't move a finger. My laptop hadn't been shut down in a few days, whichever influence that might or not have. Curiously, this random test yielded P2740 on 3DMark11.. I ran a few more and they were consistent, topping at P2746. Which is 80-90 ahead of my regulars with the same clocks, under above conditions.

I then did a lot of testing, switching power options, changing minimum processor power states, programs running, dual/single monitor, and many other stuff very much possibly irrelevant. Here's what was significant:

First of all, P4G's Entertainment power mode produced better graphics score than High Performance (or P4G's own), at the expense of very slightly worse Physics score, and therefore higher 3DMark11 scores. No idea why.
Raising minimum processor states actually lowered 3DMark11 scores as well. Setting them back low would increase again. No idea why either.
Benching with dual-monitor up (one benching full screen, the other with MSIAB / Skype / some Windows gadget) actually gave better scores than with single display. No idea why, again.

I know benching is what it is, but even then I can only guess at the reasons behind these differences. So here I am, asking if anyone has any insight, just so I could understand a bit more.

PS: To close out, while typing this post I decided to throw in another random 3DMark11. It gave me P2773. I noticed the only difference was that I had the League of Legends client running. So I decided to do one more test:
Running it two times more with the client running, I got P2772 and again P2773. Shut the client down, and I got P2744 and P2742. Reopened it, and it went up again all the way to P2779. Wut?? It seems I'm either a complete newb with this or that 3Dmark11 is just a bit random with the preferences.

Any ideas are highly appreciated xD

 

First of all, wow. I've never seen anything like it.

Maybe what you should do is reinstall 3DM11 and upgrade to GeForce v306.97 WHQL.


I also read the Dell M6700 review, although the conditions were not same as yours. The OP got a higher GPU score when he runs 3DM11 and Prime95 (CPU load) compared to only having 3DM11 run.


You might also want to use the windows power management to manually set stuffs for a particular power plan, I've never used the P4G control panel before.


/:

That is quite weird, try asking this question again in the N56VZ's owners lounge to get more answers.



But other than 3DM11, did you try running an actual game-based benchmark (3DM11 is synthetic) like Crysis 2 or Resident Evil 5?

 

Thanks for the reply. I think I updated 3DM11 just a few weeks ago (don't remember very well, it asked for an update iirc), and as for the drivers, I performed a lengthy, clean install of the 306.23 WHQL earlier this same month.
Neither seems to be 'outdated', so for now I'll leave them as they are. Once I do update them I'll be sure to post results though!

As for the Dell review, well, I don't know why either but it does resemble my case in the basic sense that he got higher scores with more programs running at the same time than with few. Long shot, but could for some reason have some sort of influence.

I did try the other power options, and those were the only significant differences. I tampered with the advanced settings in many of them so the names themselves don't really make any difference.

And no, I haven't benched those yet. Let me look it up! Thanks

(meanwhile, onwards to the owner's lounge )

 

I wish you the best of luck!
Post back here if you have the solution

 

Hi!

Can anyone tell my which notebook has better OC capabilities? I've seen the y580 Lenos got good results, but I am also thinking a Dell's 7720 with 650M ddr5 (may it have a better cooling due to bigger size). Anyone can give me some advice? Which one should I go for?

 

The vcore is the same, the difference is the unlocked +135MHz limit
As of now, neither MXM 660M or integrated 660M has an OV BIOS

The G55 does not have an MXM card due to the size (asus's claim), but what's funny is that MSi can make a 15" laptop with an MXM board and an extra HDD slot
Even with the MXM G75, asus uses proprietary cards to disable user upgrades (you know, profit)

The Y580's cooling is better or comparable with the Dell. It also has a better 660M (2GB DDR5)

Getting a laptop with a screen two inches larger does nor mean that the heatsink is two inches bigger

 

Sadly...

 

I would take the Y580 instead of the 7720, not only is it smaller (15" v 17"), it also has a 660M

But tell me how it goes in your end

 

Just an update Mobius,

It seems as though the more I free up the computer of background programs, the better my CPU scores (higher FPS during CPU workloads / better Physics score). But for some reason this comes linearly at the expense of graphics power...

For example:
-- with 4GB of RAM in use with many different programs running, GPU scores go as high as, and CPU as low as, this:
NVIDIA GeForce GT 650M video card benchmark result - Intel Core i7-3610QM Processor,ASUSTeK COMPUTER INC. N56VZ score: P2764 3DMarks

-- with 2GB of RAM in use with almost everything "optimized", GPU is for some reason severely hindered, while CPU workload improves (not weird on that department I think though), going to complete opposites as these:
NVIDIA GeForce GT 650M video card benchmark result - Intel Core i7-3610QM Processor,ASUSTeK COMPUTER INC. N56VZ score: P2717 3DMarks

Why would the GPU suffer so much? Could it be not enough power supply? I've no idea... yet

 

The 3610QM+650M uses 45+45W

The PSU is 120W I believe?

 

Yap, it's 45+45, and my charger is 125W so I don't think that's the issue. Although...
Just 2 days after getting the laptop the charger broke, and spent a week away being repaired.

 

Will keep visiting for more update.

 

Ros, try to shut the screen off (backlight) and the keyboard light to maximize available power.

It is also a possibility that 3DM11 is bugged and you must contact support to implement future fixes.

Cheers!

Btw, how did the RE5 bench and Crysis 2 bench go?

 

Thank you for the guide!

I just wanted to share my results with a Lenovo Y480 with 650m (GDDR5). I was able to run 3DMark11 at 1200mhz but I noticed artifacts. I bumped it down to 1175mhz and its running great. ASIC Quality is 73.7.

I use a shortcut to NvidiaInspector with the -setGpuClock:0,2,1175 -setMemoryClock:0,2,2000 -forcepstate:0,0 command.

1175mhz- 3069 NVIDIA GeForce GT 650M video card benchmark result - Intel(R) Core(TM) i7-3630QM CPU @ 2.40GHz,LENOVO Product Name score: P3069 3DMarks

1200mhz- 3120 NVIDIA GeForce GT 650M video card benchmark result - Intel(R) Core(TM) i7-3630QM CPU @ 2.40GHz,LENOVO Product Name score: P3120 3DMarks

 

Well, at stock they have the same price here. I would choose the 7720 since that is a better multimedia desktop replacement, but do not want a relatively weaker rig as the Y580. My main concern is that I heard the dell is having issues cooling an i7, so I am not really sure it could handle also an overclocked 650M (my hopes are quite high that the card has good potentials, since the alienware ones performs quite well).
On the other hand they have basically the same card. A 384 cuda cored Kepler with gddr5 on 128 bit. So if I could get the same performance on the Dell, I would definitely not choose the other. (Of course the Y580 is not bad at all, it is just me who is more attracted to the other )

Thanks for replies!

Regards.

 

Glad that you decided on the laptop

 

Mobius, sorry I've been away for a while, lots of tests at uni.

As for RE5 and Crysis2, I've only run the RE5 one yet, will run the other one when I have a bit more time.

Result was roughly 42 FPS with max settings for fixed scne, and 36 for variable (run for... 5-10 minutes, didn't keep track).
These numbers don't mean anything to me though, had never run these benches.
Or were you asking me to compare results under different loads / clocks / etc?

 

Test them under the same clock/settings, but make a different scenario where you load the CPU/use another power scheme etc

 

Which method is better for OCing? This thread or unlocking the vbios? ( [M14x R2] VBIOS mods - unlocked overclocking limits, voltage tweaks, modified clocks - Page 7)

Also would it be a good idea to disable my CPU Turbo Boost 2.0 since it uses the same heat pipes as my GPU? Especially if i enjoy streaming, which uses up CPU resources

Would i need to change voltage in correspondence to higher frequencies?

I have a 2 GB GDDR5 650M. Would setting my memory clock to +1000 be safe and stable? I have it set to +250 at the moment.

 

Disabling Turbo Boost is not needed, since the 14x's cooling system is more than adequate to handle a 3610/3630 paired with an OC'd 650M.

Using an unlocked vBIOS, this method is no longer necessary since you have bypassed the +135MHz limit in the BIOS level. You can use normal OC'ing method (afterburner)

 

Well currently i can't clock higher than 135Mhz. I haven't flashed my BIOS yet either. My CPU is a 3720QM if that helps with anything. Would I need to change anything with my voltage to compensate for the higher power usage?

 

No, you will not need any undervolting measures to keep temperatures down. The 3720QM can be overclocked (400MHz) to give a performance boost.

 

At work so I can't read through the entire thread at the moment so I apologize if this is covered already but,

Anyone done a higher than 135 clock on a Razer Blade? I'm getting ready to try to do the forcestate thing, but I've got no clue how to create a .bat file to keep the settings after a reset, and doing that each time I reboot will be a pain.

Trying to see if there is an alternative vBIOS I can use here, or if someone can kindly point me in the right direction as to how I make a .bat file and use it to start on windows start up?

 

is there anyway to shut off wot dynamic boost on the gt 650m? i have the unlocked bios

 

With my guide you disable the dynamic boost until you reset the clocks.

 

Can someone help me with nvidia inspector? I have ASUS N56VZ with GT 650M 2GB DDR3 graphic card. I downloaded the program and ran the overclocking section but I see only 2 performance levels - P8 and P0. There's no custom performance level (like P1 or P5) to overclock my GPU. Any idea why that is?

 

Try updating your drivers to 306.97 WHQL and make sure you have the latest NVIDIA Inspector version

 

Are there any differences between MSIGE70 660m and Dell / Asus 660m? Is there a simple way to change the BIOS? i have so much problems at win8pro with nvflash.

 

Hey man! Can u send me/write down the exact batch files and settings u use? (which is stable) I have gt650m ddr5 (m14xr2) video card and I read this topic and see that u have great experience about overclock! Your result was convincing, but Im telling the truth: I'm a beginner
Thanks for ur answer!

 

Yes there is. The G55's BIOS/vBIOS is tied together, the G75's vBIOS is separate.

While the GE70 uses a different combined BIOS/vBIOS

 

thanks for the reply. which is 660m from the MSI overclocking will be more difficult? I installed nvidia inspector and I locked on max 135. I was looking for a half-day any tutorial overclocking on msi, and I found nothing. can anyone know how to unlock the BIOS?

 

Ask Techinferno (svl7) or prema/moral hazard from BIOS-MODS

A 660M in the GE series have been successfully OC'd, look in earlier pages for a guy named "vaultboy"

 

http://forum.notebookreview.com/gam...d-max-clocks-oc-stability-14.html#post8857591

You need to read all of his pots. He didn't write both the reason why his clocks weren't in effect at the beginning and how exactly did he manage to OC it. Also no 3D Mark score

 

Alrighty, using the cmd prompt method for forcing p5 state I got stable clocks on my Razer blade up to 1170/2900, I think I could get the mem up to 3000 but I didn't wanna push it. 3dMark11 Score of 3208. Runs hot, 80-82c, and the fans are fairly loud on this machine, so I don't think I'll be doing very much OC'ing into that range, but good to know I can do it! Thanks for the info in the thread guys!

 

Hi, with my new Dell there is an issue with the boost – at some point I remember it working, but since then I can’t get it to work. I tried this guide and while the memory overclocks normally, the core won’t go above 745MHz no matter what I do. I tried last WHQL driver, the last beta driver and the last Dell specific driver. I guess I need to spam Dell’s support forum? :/

 

Did you use option of clean install driver?

 

Mobius 1, great guide! Here's the result from my Y500: http://forum.notebookreview.com/ideapad-essential/700135-y500-gt650m-overclock.html#post8987802

 

Glad that you're able to do it

What other things that you have to change (system power profile etc?) to break the limit?

 

I did but I might try again...

 

What GPU do you have?

 

Huh, I thought I had it in my signature x). GT650M with GDDR5.

Update: Huh, so I manually downloaded and flashed the latest BIOS:
http://www.dell.com/support/drivers...-17r-se-7720?driverId=GH4PH&fileId=2970873797
And so far it seems to be boosting again. I'll see if there are any major drops, otherwise I probably won't push it because I don't like the noise and I have the i5 version with a 90W adapter (which I love because it's so light, just in this case it "might" get unstable).

 

I've been unable to clock the GPU core of my GT650M with 2GB GDDR5 higher than 1000Mhz. I used clean install with my Nvidia drivers. Clocking higher than 1000Mhz will cause BSOD...
Anybody idea? Is it the Dell, or the bios of the 650?

 

(copypasta'd so maybe someone in this thread can help me)

Okay, maybe it is just me, but every time I setup a value for nvidia inspector I it gets 'locked' into that value, and doesn't change unless I use a different value for an underclocked state. This is all fine, however, if I restart/turn off/ close the laptop it then goes to 135/405 and stays there. Not even using my nvidia inspector .bat works to restore the overclocked state.

Here is what I'm using for my overclocked .bat

And my underclocked .bat

here is a screen of my y500 after the clock speeds/memory speed has been 'locked' (also, using latest driver) Not to mention, trying to put the clocks on 1110/2900 and applying them from nvidia inspector simply puts the slider back down to 405/800.

View attachment 88936

 

I can't get this to work on my MSI GE60 (GTX 660M) :/ . When I run the bat file nothing happens (the Turbo button which shows the GPU being enabled lights up for a second) and if I start Nvidia Inspector and set the values manually the sliders just jump back to where they were. I'm using the latest Nvidia Inspector and the latest GPU driver (310.70 WHQL).
Any ideas on whats wrong?

 

Can someone attach both MSI 680M unlocked VBIOS(s)?
