Overclocking 760M GTX

By 'similar to 765m' do you mean you were able to overclock the cores to 797MHz (with boost to around 900)? Because with the 135MHz OC limit, I can only overclock to 750+MHz (with boost to 830+MHz, can't remember the exact values as I am away from my laptop). The base and boost clocks are still different, in the end..

 

mine is 763 with boost 854mhz..but with higher memory clock than in 765M(+295)..i checked on notebookcheck and i gained 3-4fps on ultra settings in sleeping dogs and its similar like 765M..cause every game runs max 2-3fps better on 765m on ultra than 760M..notebookcheck is a very useful site..it has every game benchmarked with almost all mobile cards

 

I just checked, and apparently my own 760m can also overclock up to 854MHz max. I guess you were able to reach 'similar to 765m' performance by compensating with memory overclock, fair enough.

And come on, man, of course I know notebookcheck. Look, I've been trying to help you, too, with your GTA 4 problems, but you dismiss my suggestions and brush me off as someone who just bought his first laptop ever. I'm not completely ignorant in this overclocking/gaming world, I know quite a few things (my previous laptop ran on constant overclock, and I'm not even mentioning my desktop rig; I've been tinkering with PCs for quite a while now). I'm just new to the Kepler generation of mobile cards and their apparent limits.

Going back to your GTA 4 problem, if your read around these forums, you'll discover that some people are having problems doing the +135MHz OC with their 765m's in their alienware 14's. The graphics card sometimes reverts to the P5 state @405MHz during gaming, since it cannot sustain the increased frequency at stock voltage. I know the 760m is different than the 765m, but it might be the same case that your 760m cannot sustain the OC'd frequency on stock voltage (which most probably is lower than the stock voltage of the 765m, and cannot be changed with stock vBIOS). So yeah, you may want to monitor your GPU frequencies WHILE gaming, if you haven't. Again, just my suggestion. Feel free to reject this, though, if you think that sasuke with his totally different rig has opinions which are always better.

 

Running Furmark and Prime95 at the same time.

Of course you are gonna hit very high temperatures with that. Those two programs have no merit in real life scenarios and to give you an example to why you can just check out the P170EM review. That notebook have 2 fans but that didnt stop the temperature from reaching around 90C when running those programs

Nope. The moron Dustin Sklavos is uncapable of reviewing notebooks: "Alienware 18 is too big. Nobody buys it. Everyone buy desktops instead" "95C is perfectly normal for a GPU. MSI engineered it this way"

He refuse to redo the review. He rather just put out BS reviews that have no merit in real life. He knew the paste job on the GT70 was wrong but didn`t bother to contact MSI or redo the review.

Tomshardware got a max 85C on the GT70 with the 780M with some sort of stress test. Notebookcheck didnt have any high temps during gaming.
That Anandtech review was faulty as hell and they knew it (admitted it in the commentary field later. Jarred, not Sklavos)

 

As an Alienware 14 owner, all of my throttling issues were due to Dell's overly aggressive throttling any time the GTX765M started running over 67C. Now that I've flashed a vbios, I don't have any throttling issues whatsoever. I've been able to run +250 core, +300 mem and pull 4950+ 3DMark11 runs with a simple a 100mV (0.1V) voltage increase. Temps stay below 75C when gaming and it's a completely different animal than it was stock.

Dell shipped it with crippled performance by making it throttle any time things started getting slightly warm.

 

well in a video of a youtube owner of a GT60 with 770M in mother russia (-10°c he said) he got 97° on the CPU while playing BF4 Multiplayer and 83° with cooler boost.. it's ridiculous how much MSI do not care about temps ! single fan on high end GPU's ? seriously ?

 

Well something is seriously wrong with his paste job or cooling system then. I have a GT60 with a 780m, and a 4900MQ and my CPU hits 78-80C, and GPU hits around 76C while playing BF4 on max settings in multiplayer. This is with cooler boost on and the laptop sitting on my lap in my bed..So no MSI does not have a problem with their cooling.

When the laptop isn't being used to game I never hear the fans.

The laptop does have high performance 1mm thermal pads, and also has PK3 thermal paste on both the CPU and GPU.

 

Yeah thats not normal. Even for MSI lol
I think there are a lot of crappy paste jobs done by MSI. Thats why you have reviews with high temps like the Anandtech review and the russian user you speak of. Oh well, it will ruin MSI reputation so bad for them.

Im with you on the dual fan thingy though. I thought my GT70 was quiet earlier. That was before I got this Alienware 18. Its whisper quiet compared. With 1 extra GPU. So yeah, I`m not gonna buy any MSI notebook if they continue the single fan designs. MSI, Clevo, Asus, Alienware. Only MSI use single fan

 

i said 95-97 without turbo cooler @ stock paste

 

I stand corrected. Thank you for pointing that out. Still, it wouldn't hurt the OP to try and monitor his CPU/GPU frequencies while gaming to try to narrow down the problem.
And we're all getting slightly out of topic.

 

has anybody tryied this method??does it work???
Overclocking gtx 660m - Page 9

 

It should, its the same kepler core

 

feels a better option than flashing bios..i will try it

 

its not working for me?nvidia inspector loads 1050/2784 level 1 (P5) using the bat file but it wont apply the clock???i guess thats cause of newer drivers that lock 135mhz limit for core

 

Do i need to flash bios to overcome the limit or flashing gpu is enought for overclock??i found this video on youtube How to Flash Your GPU BIOS - YouTube

 

it's not the same process for the acer, the vbios is merged with the main bios so it's hard to attain it !

 

hey do you think that i can overpass the 135mhz if i downgrade to older nvida drivers that allowed more than 135mhz overlock(using inspector tool and aplying that in bios with msi afterburner) and than put again new drivers which limit that option?

 

The 760m and 660m use different Kepler cores which is why the 760m is much more powerful.

 

not the exactely same core, meant architecture my bad

 

Any solution to surpass the limit of 135mhz overclock?

 

anyone can help?

 

so long time no answers means dead thread ?!!? anyway i m interested in this and found some forums that modded bios for many gpus except the 760m which if we request the might do too...

NVIDIA Kepler VBIOS mods - Overclocking Editions, modified clocks, voltage tweaks

also there is another one for acer which there were some success...
ACER V3 772G bios for overpassing 135mhz overlock limit

Hey guys,
I've overclocked my GE40's 760M to 836 MHz base clock and 2126 MHz memory clock.When I ran the stress test (Unigine Heaven 4.0, DX11, ultra quality, extreme tesselation, x8 AA, 1600x900), I noticed that, for three brief moments quite far apart from each other during the 10 minutes, there was a slight flash of textures in some parts of the frame. Also,my GPU temp did not go above 72C, which is strange because at 816 MHz base clock and 2106 MHz memory clock (at which there were no such flashes at any point during the 2 tests which I performed on it), the temp would rise up to 75C Max. Does this mean I should stop overclocking?

UPDATE: I ran the test at the same settings again and flashing was observed a few times again. Can I stay at this clock for games?

 

Probably not.. You might want to decrease the core clock by a bit as your core might be too stressed..

 

I don't think I'd need to lower the clock. I played a few hours of Skyrim (modded) yesterday and didn't notice any problems.
What I want to know is what caused the flashing on the Heaven benchmark; the core clock or the memory clock?

 

GDDR5 is crash-resistant. If you're crashing, it's the core clock. However, a too-high memory clock can also make the core unstable. It's best to use a scored benchmark like Heaven or Valley to test memory clock. If your score suddenly drops, your memory clock is unstable. Going much beyond that starts to result in flashes and other visual glitches.

 

i have 760M and my memory clock is 2750mhz and its stable but the flickering begins for me around 2780-2790mhz and thats why i reduced it to 2750.My core clock is 1055mhz but at 1.050V voltage and i use a vbios and also i have unlocked advance menu in bios menu but i dont like to mess with it cause it can brick notebook especially if disabling integrated gpu.

 

I wasn't crashing but a couple brief texture flashes were observed. My score is still higher than it was with lower clocks (436 on Heaven 4.0). Does this mean that I can keep increasing the memory clock?

 

memory clock wont give you much fps boost its the core clock what is more important.I think you should be fine with 400mhz.Most people overclock memory at least 400mhz and after that they test if they can more.Whats your voltage?

 

Lower memory clock until no more visual artifacting. Also core clock generally more important for performance as Dmitri said.

 

Wait Wait.. Wut? Core clock is more important? I thought memory clock was...

 

You can test it yourself.

 

So I'll decrease memory clock and then see if I can safely increase core clock for an additional boost in performance.

Core clock is more important as it makes the GPU run faster in general.

 

Hey how didi you get past 135 limit for core clock ? i m trying to flash a new bios but nvflash wont recognize my card...i have asus n56jr with 760m...

EDIT : ok finally nvflash recognized my card, optimus was the problem, i modified the driver and worked. can you please share your vbios ?
