I've been doing some extended long term testing in benchmarks & games with different overvolts & overclocks to work out a range of long term stable overvolt/overclock settings, and I thought you guys would be interested in the results because it might help you work out your own stable settings.

First thing I noticed is that passing through a 3DMark11 benchmark run sucessfully was not a measure of long term stability. In fact long term stability was usually gained by dialing back core clock by one notch (13Mhz) after achieving a successful 3DMark11 run. Second thing, there seems to be a direct linear relationship between volts & stable overclock frequency; if you take a look at the attached picture you will see that the graph is linear, so that could be useful for you to use to help dial in your own further overvolts/overclocks.

Hope anyone that reads this will find this useful or interesting!

EDIT: I was kind of flabbergasted at how linear & exact this relationship was!

Great job man! Thank`s!

But this is only for your video card. The fact is that any overclock is a lottery. How lucky enough. Much depends on the ASIC cards, and some other factors. I seen some laptops with GTX670MX and 1,1V did not take more than 1070Mhz.

"Klem so just to clear everything up? All of the info i need for windows, mac adress and all will stay the same, correct?"

Yes!

Can this be done to 640m? mabye a unlock bios ?

Yes of course. Why not.

When flashing my bios, all of your personal data (Windows keys, MAC address, serial number, etc.) still all your native.

no! you can have all by using official bios: I've oc'ed my graphics for testing to 750mhz gpu and Battlefield 3 is ok, no artefacts. Most of the unlocked menus are useless and the 0.0.2 gpu voltage increase doesn't work on all GTX 670M [my B revision doesn't get moded] so I get not even one benefit from using moded version...

Because temp threshold doesn't work in Bios [i would like the fans to kick in at 50degree and full load at 85degree], I will seek for the gpu +0.02 increase only

You are wrong. Why not?

killerpc has a laptop with a GTX660M and in his case, with this bios mod he will get 1000Mhz on GPU. It will increase its performance in games. Definitely.

In addition, with this bios mod he will get unlock the Nvidia limit only +135Mhz on GPU and will be able to overclock her GPU to 1150-1200 without overvolting. This will make it even faster her laptop for games.

If you want overvolting for your GTX670M ("B" videobios) +0.02 V and 820Mhz+ on GPU, write me to PM.

is this worth the hassle to install this for the increase of performance?

Yes, of course this increased performance of your laptop in games.

Nobody can help me?

Ok. Try this.

HI guys,

As a professional Pentester, I need to work with Linux, as many pentesting tools are made for this platform (Backtrack, Kali linux.....).

I own the original 750 Hdd/Windows 8, and i put a PLextor Extreme 128Gb on the other bay.

I tweaked the Bios 223 for better performance, but there is still NO WAY to choose booting from the Hdd or th Ssd, as the Uefi system disable every non Uefi systems.

If someone may help, I would give a (littl) contribution....

Thanks,

Clemson, Nice, FRANCE.

Try go to your BOOT Tab in BIOS menu and DISABLE Fast Boot, Enable Launch CSM, DIsable PXE Rom, then go to your SECURITY Tab and DISABLE Secure Boot. Save changes in BIOS and restart.

or

- Enter the BIOS setup menu by pressing and holding F2 key when powering on.

- Switch to "Boot" and set “Launch CSM” to Enabled.

- Switch to "Security" and set "Secure Boot Control" to Disabled.

- Press F10 to save and exit.

I tried to overclock my Fujitsu NH532 GT 640m LE but it only gives +135mhz. Please help mod this American Mega Trend bios. I have uploaded it to my dropbox. Here's the link.

Tried different offsets none stable result in a freezing of the computer or a random restart

If i don't change any offsets those don't arise. Thanks though my hunt for a unlocked vbios for 770m continues T_T

Try next version.

can i return to the original bios?

Yes, return to the original BIOS is very easy. Just flash your biosbackup.bin file.

Hi Klem, I'm curious, are you working with svl7 on these new modded vBIOS files, or are you doing it independently? Do you mod them in the same way that svl7 does?

Hi Robbo.

I make my mod bios and mod videobios independently from svl7. But i know that svl7 makes mod Bios files is very well.

I think that we both make them with the same way. But perhaps in different ways.

ok Bios Version 80.06.06.00.01 (P2303-1e00) https://www.dropbox.com/s/3l5ehe91fg6enly/11E0.rom

Here is my current vBios

thanks

Yes, link died.

Got mine to push 100, but encountered a strange flickering at lower brightnesses.

A month ago I got a black screen problemWas changed for motherboard, returned everything works.But The backlight keyboard does not working Please help:concern:

Warranty expired

Keyboard Light Fix (Gary Key)

I have succefully flashed my bios with the 223 modded bios, i follow correctly the instructions but my keyboard backlight doesn't work, what i have missing ?

Keyboard Light Fix (Gary Key)

I can get 100Hz with my G55 too, and 120Hz+ but with some aftifacts. Unfortunately, you can't really get more than 60fps on any modern games in 1080p

You have some aftifacts on 120Hz+ or with 100Hz?

The solution to this problem lies in the topic. I do not remember what page. Look closely.

One question,

I can flash the video BIOS without flashing my system bios ?

Nope. It is impossible.

- - - Updated - - -

when i run the backup.bat file no backup is being created. what am i missing?

But what happens on the screen?

Video bios is a part of all system BIOS.

Who can do a vbios for gtx 660m with an overvolt at 1.15V for oc the core clock speed at 1.350 mhz ?

Sorry for my bad english, i am french

I can. But overclock is a lottery. Some cards will earn on the frequency of 1350, and some only at 1280 . You need is only the video BIOS, or the all system BIOS?

Would this work for GTX 670M ??

Hi!

For GTX 670M work mod bios from the first post of this topic.

hi,SVL7

THIS IS the clevo P150EM gtx675mx 4GB original vbios.653/900

PLEASE MOD it to OC and OV(yes~ over valtage),to 1.05v or 1.08v:Banane03:

I will test it

Thank you:tennis:
