GTX 670MX Overclocking [Updated-custom BIOS file] - Page 61

post #601 of 610
Yeah this gpu is a monster of overclock, people hardly believe me when I tell them I doubled the frequencies, even less when i say that I nearly doubled the performance (which is quite obvious when you double both the core and the memory clocks)

Wow some of you guys have really pushed this GPU to the extreme, I started this little project because I was just having some fun but I'm glad a lot of people have made good use of it. I won't be on here much anymore until I get a new gaming laptop or start building another desktop. Work has been keeping me quite busy.

Sorry I haven't been able to answer anyone's questions. I probably won't be able to since I have been traveling a lot lately and barely get internet access.

Goodluck to all thumb.gif

It's good to see you back.

Hopefully you have more information about the unlocked bios.

Do we change all of the values to allowed or what ever in AMI bios configuration tool or are there certain options we can enable and all of them will be available?

What are some of the options we can enable that will help with making the CPU stable speed and not turbo boost, just stay at max speed.

Are there any options to give the graphics card anything? Any boost? Prevent that weird under clock thing when your running on battery and the screen dynamically gets brighter or darker?

There is no options to give the graphics card anything, I was only able to overclock and overvolt the graphics card due to messing with the vbios for the graphics card, that's how I was able to push it that far but I couldn't have found the voltage table without the help of gothika(if that's how I remember his forum name) I have that modified vbios file on a USB stick somewhere but I just can't seem to find it.

The screen getting dark and bright thing is a good thing and is controlled by the Operating system, not the bios. It's within your power settings(I don't want to get too deep into it)

You can't have the CPU disable its throttling since it's not really an unlocked cpu(or an extreme CPU; according to intel) so no way to disable those options.

The reason I unlocked the bios was so that I may control spread spectrum and be able to play with ram timings for better performance. There is no other useful option in the Bios. You can unlock it with amicp but you will need to fix the checksum otherwise you'll brick I believe and I did that through hex editor.

Everything is slowly coming back to me lol, well my memory of the process anyhow. I'm typing this from my phone. My desktop took a dump so... Waiting for my new laptop to come in.

The way I outlined how to unlock the BIOS in my forum post, you do NOT need to HEX edit the file, it just works.

The screen getting bright/dark wasn't what I was referring to. Plug in your battery AND charger. Open 2 tabs, but not side by side, full browser. With the charger in, switch back and forth between the dark (almost black website) and the bright (almost white) website. A dark and bright website are what you want open in those 2 tabs. Now, noticing that NOTHING changes, unplug the charger. Now switch the tabs. You'll notice that the lux (color temp) of the screen changes, as well as the color and saturation. I do not think this is the OS XD I have max performance enabled with everything max performance and never sleep, max brightness.

Which options would you recommend then for unlock the BIOS?

We already know how to overvolt and overclock the vBIOS now, Kepler BIOS Tweaker support's our chip now! You won't be needing to provide a vBIOS file or get into HEX editing it.
post #606 of 610
Hex editing provides a lot more than the Kepler Tweaker. No voltage drop, voltage slider and much more. Do not give up guys. All the credits go to Dreamonic.

Edit: before I forget: only bios 201 gives you PCI-E 3.0. It is not on the website but most of you have it in your backup partitions.

i had a question i overclocked my gpu using Total Commander using this command:"nvidiaInspector.exe -setVoltageOffset:0,0,0 -setGpuClock:0,2,801 -setMemoryClock:0,2,1400 -forcepstate:0,0"
it was working fine with temps at 50 deg then suddenly i kept getting this msg "Nvidia display/kernel mode driver has stopped working " 5sec into any game, even 5sec into the 3dmark vantage.
but it went away after a reboot.
was this caused by overclocking at gpu clock at +200?
srry i am a beginner so i am gonna stick with the +135 for a while.

If I can get 20 people to add me on Skype or Google Hangouts, I'm using my iPad, I will right now finish the tutorial I made with all the steps to do everything.

It's November 24th 2014 at 9:33am PST (-7/8)

Hello. I have an Asus G75vx with gtx 670mx. I wanted oc. I'm afraid of flashing the bios because i could brick it. My current voltage (default) is 0.925 mv 600mhz/1400mhz.... msi aft let's me +135/+1000 (735/2400) and is stable. In nvidia inspector i found command keys to go to unlimited but driver crashes over 800mhz.... at 950 screen black and reset ,after that is default 600/1400. Max i can get in stable clocks (with default bios) is 770mhz /2400mhz (gpu, memory). Performance is tripled from default. ok... mi laptop is very clean (fans everithing) i get in furmark over 70* .... 75* max i got in 1hour stres test.... if i let it more i get 80*...... mi question is: how can u have 1000mhz and temp below 80*, dude u are lieing!!! at 1000 u need water cooler sistem. Aniway i'm not here to judge, i'm here to sy mi story, im very tempted to unlock gpu bios. But 75* is enough for me.... so i got 770mhz with 2400 mem (at 2800+ i get artefacts).... at 4000 they are incredible ,can't understand anithing from video images smile.gif) ..... i came close in performance to gtx 770m.... this is more than enogh for me biggrin.gif (mi oc is aprox 30%).... I think that at 1200mhz (double default) u need double voltage to stabilize, don't gv me +0.5mv inc (1.25v) that isn't enough , u need 1.8 at 1200 .... now this card consumes 75watts, is it posible at high oc to consume more? yes. So what u do with the 150 watt adaptor? gpu steal power from cpu and rest of computer, this is not stable sistem to me.... btw again... at 770mhz i get driver crash : 1 crash in 5hours max (in 5 seconds it restores ,i dont loose data and i continue playing). Good luck to those who push more biggrin.gif hope ur card doesnt melt........ ps: at 850 core clock (drivers didnt crash 2 min so i fast tested it) i got undervoltage 0.925 went to 0.900mv on graph it was waves... at 770 i get continue line. at 900 i cant test cause dont run. driver 377.5 i think,,, one person mentioned it on oc sites to be best stable driver vers.
post #610 of 610
That was an almost 2 year old post. The latest drivers are the most stable for overclocking now.

And you really can get low temps after changing the voltage. I don't know what your reading but all computers are different. One computer might need 1.8v to reach 1000+MHz on the core, others only need a small bump.

For the GTX 670mx in our laptop, a voltage increase to 1.25v will allow you to set your core clock to 1000mhz and it won't harm your CPU, GPU or your power supply. Also, no one should be getting 4GHz on the memory clock. The highest stable is 3GHz.

At 1GHz core, 3GHz memory and 1.25v, max temps should be around 80-85 celsius even when gaming. The cards are designed to run that high. It's ok and safe. Yeah it's hot as **** but it's not going to damage the components.

Anything 87 or higher would be a problem, might actually cause artifacts before damaging lol the cards are super high quality and can withstand a lot.

If you don't enjoy the hotness under your hands, just get a laptop cooler thing. It's made of plastic and has some slip resistant foam stuff on top and 2 fans on the bottom. Take off the 2 bottom covers under the laptop and you can get your temps to 75-80.

Your safe to experiment man as long as you use the methods and programs we are using


DO NOT USE THE DOS VERSION OF FTK! That's when you can brick your laptop. Use the windows version of FTK, that's much more safe.

DO NOT force a flash if you get a Size Mismatch error. That's when you can brick your laptop.
