Maybe you can find something in the document.

UPDATE:I THINK WE MAKE IT!!!!!
My boss called me just now,i'll be back and explain asap.

Sounds promising! Please update when you get a chance, thanks! Hope boss didn't give you a hard time

Job done and I'm back.
Again,your way of modify is totally CORRECT.
The problem is,as you mentioned,I actually messed up with NVRAM variables value.That value of 1/2/3/4-core turbo ratio control shoule be HEX,and I took it as OCT.After read that thread you provided i finally realized this problem.
Now,my gear works like a charm.PLS look at CineBenchR15 result down there.Around 670CB for stock and around 720CB after overclocking to 40/40/40/40x.And as we know,720CB is higher then a stock Haswell i7-4930MX (around 710CB)!

Dude,thanks for all thing you did for me and you are a real genius:D
For now i'll try to push this thing to its limit,and find a decent value for daily use.Later I'll dig into the ACPI table and try to figure out the specific compatibility problem between M6700 and mobility Quadro P5000 graphic card.Could I request for your help again in the near future?thanks in advance!

Great you found the correct method, I was going crazy as it seemed like my first time actually unlocking this was correct but it failed, so I was sad

Very nice overclock and scores, for a laptop too! Faster than my system I'm using now I think

You're very welcome, and thank you for sticking with me too while we figured it out together!

I'll have to call in help with ACPI tables, that one is definitely above my head, I think.... I thought assembly/disassembly use was too, until this 0x194 lock help me figure it out, so thanks to you for making this thread and having me dig into IDA again!

@Blossomcrown @Lost_N_BIOS Congratulations!

Thanks for checking in @oldirdey and thanks for all your help/discussions on assembly we've had too, it kept me going on figuring things out.

Now I just need to learn how to change a DVMT selection choice from 128MB to larger values like 512MB or 1024MB, I thought I had it but reality it only changes the selection labels
Might have to hit you up on PM to look at that for me, if you don't mind? If you're OK to check let me know in PM and I'll send, thanks!

Thanks for trying to provide useful infomation!
We finally made it thanks to LNB's outstanding works and helpful community members just like you :)
Have a nice day.

For my machine I think I have seen the DVMT settings somewhere in NVRAM variables list,not 100% sure about the certain machine you are researching.

Thanks again to you as well!

The DVMT I'm needing to change has to be edited in/by assembly, like this edit I made for you, it's part of the setup module of the BIOS I'm trying to sort that out in, it's an Acer 1830Z (With super-limited options shown in Intel tools, it does not open it's menu options fully, but that wouldn't help anyway)
I don't need to change the setting, well I will once done, but I need to change the actual allowed values and the included variable/instruction sets that call them into play. Change option of 64Mb, 128MB, 256MB for example into 128MB, 512MB, 1024MB, or really just change one of them into a large amount would be ideal.
I made some edits that I thought looked like it would change them, it changed the code and auto updated the instructions defined value info too, but in reality the BIOS only changed the labels, once selected same original values were applied

Pleas help i have the same notebook and i will Overcklock my CPU too. How can i get the modded Bios File?

@pseudodeed - new links added at post #17, thanks for the dead link heads up!

Hi Lost_N_Bios,

thank you for the links. I have tried to flash the modded bios with a programmer but unfortunately is hasn't worked.

Because i have two EEPROM (8MB + 4MB) on my Board i have tried to split the 12MB Bios to two parts so it will fit in the two chips.

Do i need to do something else to flash the modded bios? Can you provide me a proper splitted file or mod my bios?


Thanks in advance!

It's OK, that BIOS meant to be "Flashed" Since you need split, here I split file from post #17 However, I recommend you flash the 12MB BIOS, because if you write this mod BIOS to your board with programmer you will loose all your original board details (Serial, Service tag, LAN MAC ID etc)
Here is the split modified BIOS, but I think yuou should wait for Blossomcrown to tell you how to flash, I sent him a PM and tagged him here.

I am not sure what method @Blossomcrown used to flash with, please wait for his reply, I do suggest you flash instead of programming for the above mentioned reason. Unless you modify these BIOS with your service tag and LAN ID etc.

Hi ok. I will waiting.
Sorry I dont know how to modifi the bios.
But thank you for helping.
