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

That's okay, the end result is what matters

Is the vBIOS for a SLi 680M different? Is it possible to just flash the GPU's individually?

 

Im new to overclocking but i got a Samsung Series 7 NP700Z7C-S01US i oced the memory of my gt 650m up to 2898mhz and the core up to 969mhz my max temp was 72c i was using msi afterburner but im guessing to go any higher on the core i have to use nvidia inspector. whats is the maximum anyone has acheived with their 650m and what is the max safe temperature u guys recommend.

 

I'm sure you could flash, I'm not allowed on this review sample. Drivers that let me overclock on my P150EM won't let me overclock either card on the P370EM, even if I disable SLI. They are locked at 719MHz.

 

Who knows "-forcepstate:0,x" what is the use value for gt640m?

 

If you open nVidiaInspector it's the P state listed in the overclocking pull-down menu.

 

Available only p0 and p8.

 

even with nvidia inspector i can only overclock +135 on the core. i read something about forcing pstate but i am confused.

 

Then you are stuck.

 

I don't understand this and haven't read it yet but it looks pretty awesome. Preparing to upload 3 Quadro k5000m vBIOS for you guys to screw around with or whatever.

The vbioses I have (and the cards I guess) were made for various test procedures as far as I can tell, so far the 1st one has a note in the boot message that says "hwdiag".

 

Haven't had any luck overclocking my SLI 680m's yet though.

 

heres a pic of nvidia inspector does anybody know how i can overclock my 650m. i havent had much luck forcing pstate.

 

Check 1st page for a 650M pState tutorial

 

i went into nvidia inspector and set p0 at 2600mhz so i would be able to adjust the memory in p5 then i entered nvidiaInspector.exe -forcepstate:0,5 into cmd. the pstate 5 took my numbers so i tried 2000 memory (stock) and i tried to bump up the core but anything from around 1100mhz and up makes my computer freeze i think its a driver issue because it was only at 53c any ideas

 

Tried the same configuration as this one. I have the same hardware (HP DV6-7084la) but I get BSOD a few seconds after launching any heavy application like 3D Mark 11 or BF3. The BSOD is for nvlddmkm.sys (NVIDIA Driver).

My drivers version is 306.23, the one tested above is 306.00. Maybe the problem is the drivers?

Can I get some help please? Thanks!

 

I think it's your drivers, I would recommend updating to the latest WHQL from GeForce.com, most HP users (Dv6/Dv7) can push their 650M to 1100Mhz+

After you managed to get the OC limit bypassed, don't set the offset to high, add only 5Mhz OC from +135Mhz to +140Mhz and see if that works, if you manage to get it working, by then it is OK to try higher clocks

 

Mmh... My drivers are up to date.

Managed to make it stable but I have some weird FPS spikes, but the overall is better:

P0:

Spoiler

P5:

Spoiler

Something off-topic:

Is it normal that without overclock (default everything) and without a fan base the temperature with BF3 at High is at 100°/105°C?
With a fan base is at 90° at max.


Let's see if I can push it further, any recommendations?
Thanks by the way!

 

Here's my GTX 660m. Not maxed out load temps at 72c runs nice and stable.

Weird, while nVidia Inspector calls out P5, I had to use the P2 state to overclock.

In any case, I was only able to get an extra 80MHz out of my 680m SLI setup:



That's about a 15% improvement over the stock clocks.

Here's the X Score. I realize this puts it well over a desktop GTX 680, by about 10-15%!

Try setting HP coolsense to max settings, set min/max CPU state to 100% at power management and cooling to "active"

Check C.Mod C.Clock Mod and Set multiplier to "turbo" at throttlestop, disable C1E.

90c is quite high, if it's still under warranty, ask tech support to do a repaste for you




@HT, try overvolt the 680M, I wanna see two 1Ghz 680M in a laptop

 

Can I turn on the p5-state on my card?

how they did it?
P.S. I think the core rate was more than 135Mhz

 

In theory, I would check Set Multiplier but I wouldn't bother checking either type of clock modulation. If your CPU is not using either of these methods of throttling then telling ThrottleStop to continuously check for this only wastes CPU cycles that could be better used elsewhere.

 

I think you are right.
C.Mod, C. Clock Mod and Set Multiplier makes no diference. FID always changes, and no other value seems to change it behaviour.

Also... What deactivating C1E does? I can't tell any difference.

 

i was able to overclock my gt650m to 1100mhz core with 74c running furmark but when i went to 1150mhz it blue screened the nvidia 304.79 crashed. what drivers are u guys using to overclock i would like to get to about 1200mhz core and 2600mhz memory? Also furmark said my gpu was throttling down to 965mhz is there any way to stop it from throttling?

 

Ah, I was under assumption that those two have to be checked /: sorry

C1E if set as "disabled (unchecked)" disables the CPU lower clock at idle, it works on desktops but I haven't tried or seen anyone disable this feature with a laptop

Try WHQL drivers (newest)

World's Fastest Graphics Cards, GPUs, and Video Cards | GeForce

 

Ah... Don't worry you already helped us a lot

But about the drivers, I've been using WHQL drivers the whole time, going above 1000mhz for core make it unstable and leads to a BSOD. For memory I'm at 2800mhz without problems, haven't tried higher.

 

Have you tried using the install guide by Kingpin? Most Clevo 650M users can push to 1100MHz. Might I ask, what vendor/memory type is your 650M?

Last thing is to check ASIC quality, (GPU silicon) check my sig

 

Mmh... I don't think I need to follow the guide because I formatted 2 days ago and installed directly the latest drivers.

The memory type is GDDR5 (2GB) and the vendor is HP.
The notebook model is an HP DV6-7084la. It is a long history how I got this notebook, HP replaced my first purchase (DV6-6c80la) about 5 times to get a proper working laptop, NEVER BUT NEVER get a notebook with the ATI HD7690M.

And the ASIC quality test shows 96.6%.

 

I never trusted AMD for laptop tech anyway xD

What driver are you on? 306.23 WHQL?

Strange how your sample can't break 1000Mhz

 

Yeeh, 306.23 WHQL.

Also made it to 1070Mhz, but any higher it gets unstable and I get a BSOD.

 

You played at 1071 just now

Also, kinda off topic, but that BF3 server was total hacks, aimbots and stuff. Got headbanged by an M9 as if it were a sniper rifle

Very nice, but how about 3Dmark 11 and a 30-minute Furmark burn in?

 

dafuq? What drivers are you using? Are you using Throttlestop?

 

Jota, it might not be his max clocks, however, if Vault can run Furmark for 20 minute without crashing by then his 1200MHz OC is legit

Weird to see how a change of vendor can have a 100+MHz more overclocking headroom /:

Haha xD

I was shocked when you can get to 1200MHz, never seen a 650M pull that clocks

Anyways, experiment some more and add +1MHz more and more to the clock

 

Why cant i Force P0 state? Running Nvidia Inspector with the parameters only switch my GT630M on Aver AspireV3-471G to P0 State in less than 1 sec...

 

The GT 630M isn't a Kepler based GPU. It's a rebranded GT 540M. Sorry. Different GPU.

 

1050/2575 and the CPU is now game stable thanks to the new PSU

 

Actually, I need to continue overclocking the vRAM since I originally set it to 2100
EDIT: It seems I can no longer OC my vRAM as it never accepts the boost value, any ideas?

I don't believe overclocking vRAM does anything for Kepler, memory controller load never passes 80% at 2200mhz, and I've observed the difference between 2000 and 2800, and there is no difference in performance.

 

Depends which kepler you speak of.

NVIDIA GeForce GTX 680M video card benchmark result - Intel(R) Core(TM) i7-3740QM CPU @ 2.70GHz,CLEVO P170EM score: P29154 3DMarks

MMMmm 30K GPU score.

 

Yes but who says overclocking the memory did anything? Meaker, you like to do benchmarks, see if there is a difference with just OC'ing vRAM.

 

Overclocking the memory does do something, I got 4 FPS out of FFXIV with ambient occlusion On/ Depth of field On. That was 854/1800 vs 854/2200. However the GTX680M still can't run that game at solid 60FPS at 854/2200 when ambient occlusion is turned on.

 

Ok, so I finally got my max OC, I got 1090/2500 and any higher gets BSOD, tested with 3DMark11

Used this " Using your 4GB GTX 680m to its safest and full potential" guide to flash my 680M 4Gb vbios and here's what i've got:





Nvidia made a great card indeed and the clocks are super stable for 24/7) I will try to get my hands on 3740qm when OEM is out! P170EM still has some potential under the sleeve.

 

Hey Mobius, if i got 1090/2500 clocks,what would the desktop equivalent to the GT650M GDDR5 2GB be and what would the laptop equivalent be? Thanks.

I would overclock it, even it it doesn't affect the performance

Have you tried breaking 1GHz? xD

If you run a 3DMark11 bench you can compared it to other scores with systems using 2500K/2600K's

Mmm, I have not discovered how to break the limit for memory clock on a kepler.

How much can a 680M on 1GHz pull? Paired with a 45W CPU wouldn't the original PSU (180W) yield the same result?

 

Mobius 1, yeah i might give it a try. But the thing is that with that exact vbios the card should throttle to 928Mhz core if i exceed 980Mhz overclocked settings. I just need a better CU, like incoming [email protected] to make the card shine, hehe))

 

Hmm, maybe the 230W PSU plays a crucial part, the card does not receive enough power?

Also, how did meaker and you get the 3740QM? I wasn't aware of a minor refresh in the mobile IVB world...
