Post Your GTX 680M Overclocks and Temperatures

Have anyone made a vbios with LESS voltage than 0.987v? Does it exist in your vbios collection Meaker?

I`m curious to what temperature decrease we can get while still have the same performance as stock clocks

 

By the way the 3D voltage on the stock vbios is 0.962v, 0.987v is just a warm up voltage when the card start up before doing 3D stuff

OK everything after this line is just for the EMs:

All the GPU-Z logs I have recorded showed a similar sign. When any game is launched, GTX680M powers on with 0.987v @718.5/1800 to check the game you started, get in game, few sec later drops down to 0.962v @718.5/1800 and stays there, exit game back to windows, voltage went back to 0.987 @718.5/1800, this is with just the GPU-Z monitoring and logging.

The funny thing is, if you don't have MSIAfterburner running while GPU-Z is running, the GTX680M won't get into idle clock zone at all, until you close the GPU-Z and the GTX680M turns off itself, so I've never been able to capture the idle clock of the GTX680M when MSIAfterburner is off and only GPU-Z is on. And when MSIAfterburner is on while GPU-Z is running, the GTX680M will starts downclocking itself once get back to windows and the result will also be captured by the GPU-Z log as well. Something is up with GPU-Z when no other monitoring programs are running.

If you tick "Display GPU Activity Icon in Notification Area" up and watch closely, when you start any applcation(IE, notepad etc) you'll notice the GTX680M powers on to check the application you are running, if it's assigned to integrated graphic, then the GTX680M will power off, if it's assigned to GTX680M, then GTX680M will stay on. And this process will also check the GPU temp and set the fan to the according RPM or even turns the fan off. So basically, the fan profile is semi-auto, it doesn't seem to move into the according stage on its own, it's pretty much relying on the application check process from the GTX680M. When you open a program, it checks the program and also sets the fan.

 

Idle clocks is 0, when nothing is requesting it, it shuts off.

 

Before getting to 0 there are other stages too If you have MSIAfterburner on and also GPU-Z on you'll notice it down clock to 270/800 @0.862 and then downclock to 135/324 @0.837 and stay there and if you have all GPU monitoring program turn off and start any application, the fan will shut off.

But if you have only the GPU-Z running, the GTX680M will stay at 718.5/1800 @0.987 like full time, it's like the GPU-Z is preventing the GTX680M getting into idle clock zone.

 

Thats because it is.

 

Are you experiencing that on the HM as well or this is only with Optimus?

Edit: My bad, forgot you have an EM

 

wow hackness, you know waaaay to much about how the 680M and the system interacts lol

So its 0.962V on full load then

 

Yep 0.962 it is. All started when svl7 asked me where's the idle clock when I sent him the logs

 

Yeah I figured this out myself yesterday too - with the overvolted vbios from Salt and svl7, it acts the same way:
- Saltius vbios: when 3d load is detected, it get up to 1.037v for few seconds then stays at 1.012v for continuous 3d load.
- Svl7 vbios: similar but with 1.05v and then 1.037v <- this is the one I'm using at the moment and it is quite good.

Also, my 680M doesnt seem to underclock to idle clocks UNLESS i got NVInspector running - with it it acts the way it should so not sure why. I haven't tried with GPU-Z and/or MSI AB.

Almost hit 27k overall score in 3dmarkVantage, need to optimize this a bit more when got some time.

 

So guys, I just got the Cooler Master Notepal U3 thingy for my AW M17xr4 with the GTX680m, and when running benches such as Bioschock Infinite bench (at max graphics) and 3DMark 11 Basic, I cannot get my gtx680m above 67 degrees celsius. Stock VBIOS, but both CPU and GPU max OC'd as far as the AW will go. It idles at 46C. The CPU at about 50C (flares to 90c at max load). Is this good? Time for VBIOS upgrade? Edit: Just around 7000 points in 3DMark 11 at this config. http://www.3dmark.com/3dm11/6345192

 

Your CPU is a bit hot there; I'd suggest underclocking it a bit. As for your video card... I wish I could get a GPU that is impossible to pass 67 degrees celcius XD

 

Thanks! Its only very rare and at max load I see a 90 on the CPU, so I think I'm fine. Not impossible to get past 67 - a long Battlefield session takes it up to some 74c.

 

Even so that's still OC'd so that should be quite good.

 

Should I be worried?

I can't run 915/2400 without artifacting at some points. 915/2500 practically vomits artifacts. Also temps were soaring at 78 degrees C.

Here's a run at 915/2125:
7153

and at 915/2200:
7213

These both seem to hit 78 degrees C.

Edit: I think it may need more voltage to reach what you reported. 940/2200 worked fine, but 940/2300 crashed, and 915/2300 worked. ?

 

Voltage? Yea most likely. And 78 C is NOT huge temps... especially with such a high OC?

 

I think your memory overclock is too high, I would overclock the core more and lower the memory down to 2300. I never go past +500 mem, as it doesn't help with benchmarking or gaming (at least on dual cards.)

You should try raising voltage to 1.05v as well. 78C isn't worrying, but I keep my fans at full speed during benchmarks so I don't see those temps, even at +342/+500 at 1.1v. Can you use "fn+1" to raise your fans to full speed?

 

Oh ok. That worried me that I wasn't able to reach those clocks at stock voltage. But is it normal that I can't reach core 940 and memory 2300 on stock voltage? It causes two or three artifacts total through a 3dmark11 run. I believe I could fix that with more voltage but it has me worried in conjunction with my 680m's low ASIC quality.

Yeah I haven''t been using max fans so that may explain the temps lol.

That's a good point about the memory clock. As I was reading through the thread it seems the core is bottlenecked until approximately 950 mhz at which point the memory becomes the bottleneck until about 2500 mhz.

 

I wouldn't worry too much about it, +500 memory is pretty high for stock voltage as well. The highest I'll run on stock voltage is +200/400 (though it could go higher,) and anything higher I bump up to 1.00v, 1.05v, 1.875v, or 1.1v depending on the overclock. Try running at 1.05v, I bet you'll be able to +300/500 without any issues. If you want to go higher than that, you'll probably need more voltage.

 

Yeah. I run 900/2200 at stock voltage. I can run 980/2350 at stock voltage, but just run it at 900/2200 because the extra few % FPS I gain isn't worth the extra heat.

 

What HTWingNut said. Thou I run at lower core, at 858.

 

Oh ok thanks guys. I guess I was a little worried I may have had a defect card or thermals and wanted to get on top of it.

 

Hi guys!

How many the stock voltage GTX 680M? I use now 7970M,but i think need exchange NV card.

 

The stock voltage for the GTX 680M is ~0.96V and 1.01/1.02V in turbo boost. Current consumption is 100W.

 

Thanks!

I hope will be cooler stock clock than the my 7970M now.Coming soon to my M17R2.
Turbo Boost can be switched off somehow?,or need always? I see some modded vbios think there also
working the boost.Someone tried undervolting 680M?

 

does anyone else have GPU usage issues fluctuating with high clocks? im currently at +375 core and +600 mem and when playing crysis 3 i see usage go from 70 to 99 randomly especially when turning fast in the game. This causes the games fpd to dip for a second and really gets annoying. Lowering the clocks helps that a little. Hope its just crysis cause my 680m is stable at those clocks


as for the topic: i benched 3dmark with +400 on the core!

http://www.3dmark.com/3dm/534045?

 

Your Graphics Score was only 6.4k at +400? Something isn't right there man. That's less than most 680ms on stock clocks...

 

Isn't that a good score for my clocks in 3dmark fire strike?
Think u got it mixed up with 3dmark11 , where my gpu score is much higher in my signature

 

*facepalm* lol sorry bro, I thought it was 3DMark 11

Nice score :thumbsup:

 

this is mine its fairly decent i think considering i havent altered the stock voltages and im running at 940mhz gpu clock and 2350mhz memory clock

Is there anything else I can do besides overclocking further to get a higher score?

EDIT: the memory clock is listed as 1,200 MHz in GDDR5 format I believe so in DDR it's 2,400 MHz.

 

The data rate is 4x that due to gddr5.

 

How about temps?

This is just 2000 points short of my SLI default score :thumbsup:

 

Sorry to necro but I'm getting a GTX 680M on Wednesday for my P150EM. I want to be able to get the extra juice hiding within the card but I don't want to have to overclock it using MSI Afterburner (or any other software) every time I use the card. This is the only VBIOS I found: svl7's VBIOS. From reading around in that thread and reading the readme, I can't tell if it overclocks the card or not by default or if it will run stock clocks and I have to overclock it manually. Does someone know the answer to this? Thanks!

Edit: Also do you know if it is stock voltage or if it overvolts?

 

On my 780M it basically makes the card run at the maximum factory boost clock constantly and preventing it from throttling down unnecessarily. It unlocks voltage controls but doesn't alter factory voltages by default, it leaves the option up to the user. It also gets rid of the +135MHz overclock artificial limit of the NVIDIA drivers.

It may be slightly different for 680M, so best to wait for someone with that actual card to answer!

 

It, as Cakefish pointed out, keeps the throttling down to a minimum and reduces FPS drops by a fluctuating clock speed. It doesn't overclock by default and removes the overclock limit so you to overclock yourself. Depends which one you choose but the rev 2 is the stock voltage.

 

Well it raises it all, not quite unlimited if you like extreme overclocking but as good as for the vast majority of users.

 

What benefit does overvolting have? I'm currently running svl7's vBIOS with 1.025v on my 680M.

 

From a non experienced with overclocking perspective, I believe it gives you more room to increase your clocks. For example running 1v overvolt from svl7 I noticed it was automatically oc'd 40MHz. I could easily push the card another 140 no problem. I tried 1GHz though and it crashed the game I was playing. I assume I needed more voltage or my card wasn't stable enough. I'm thinking about flashing to the 1.025v version now that I feel comfortable with flashing firmware after a successful vbios and bios flash two days ago.
