I've been working on this for a while and I just can't seem to figure it out and wanted to ask around if anyone knew or have an idea of how this worked. So AMI Aptio IV Bios - uses the boolean array 0101000101 to unlock the Chipset Menu. However AMI Aptio V Bios is completely different; extracting the setup module shows an entirely different format. I managed to find this which I believe may have something to do with the Chipset Menu being hidden; Using UEFIExtract on Setup module. 0x15E54 Suppress If: {0A 82} 0x15E56 True {46 02} 0x15E58 Ref: Chipset, Variable: 0xFFFF {0F 0F 20 00 02 00 03 00 00 00 FF FF 00 13 27} 0x15E67 End If {29 02} --- I changed it to ------ 0x15E54 Suppress If: {0A 82} 0x15E56 False {47 02} 0x15E58 Ref: Chipset, Variable: 0xFFFF {0F 0F 20 00 02 00 03 00 00 00 FF FF 00 13 27} 0x15E67 End If {29 02} Once I made the changes I flashed the modified BIOS and the Chipset Menu is still hidden. I've ran out of ideas and was hoping someone would perhaps know something that may help. I've used AMIBCPv5 to set all menus to USER so that I can unlock the hidden options which worked great but now I can't get the Chipset Menu tab to show up in BIOS. Any ideas? This is on an Asus G752VL -- Bios can be downloaded from Asus support page; if someone wants to take a look and get some ideas; https://www.asus.com/support/Download/3/833/0/1/R7OU0ay4MTR8jpC8/45/

Do the repaste, I had the same issue with my Acer 5750G with GT 630M and an i3 (Given the i3 probably produce less heat) Anyhow I was hitting 85-90C constantly. I repasted with Artic Silver 5 (Still good stuff & easy to find) I always do a good tiny X of thermal paste in the middle I always found it to work best than the dot) Now I idle around 40C and pushing it I don't go past 65-70C its been great, Do it for GPU&CPU. Clean the fan out and clean the cooling fins of the laptop cooler. I think there is a few tiny thermal pads in there if you do find any don't throw them away reuse them or replace them-

Have you tried removing the CMOS battery? take apart the laptop, find it, remove it for a good minute or so, reinstall- reboot and see what it does. Or else you can get the laptop to run Recovery Flash. I think its Cltr+Home upon bootup or something, but you have to have a BIOS file to flash in your drive. Google around as I don't know the details so well on the top of my head. You could however always get a Test clip and reprogram your BIOS chip that way, better than a paperweight laptop.

Yes that seems to be the issue, they didn't read the warnings because FTK will state that there is a Size Mismatch and asks if you still want to flash, I made the mistake of saying Yes once and bricked my laptop prior_ I hope others get as lucky as I did and got theirs repaired under warranty. Forgot the rep I talked to, but I told him I bricked it doing a flash and he just said, send it in for repairs and that was that =] If you want to flash your BIOS make sure it is size 6144kb, NO larger, NO less The BIOS file you download off the ASUS support website is like a few kilobyte larger but this BIOS is flashed differently and can only be used via Asus EZFlash or Winflash, now with this BIOS, its made to retain your original Windows 8 Key and Original Laptop Serial number. I don't know how it does it but it just does so that BIOS file flashes in a completely different way. FTK doesn't flash like Asus EZFlash and Winflash, instead FTK just completely flashes the BIOS file to the BIOS Chip. Meaning if the BIOS file size is 6144kb it flashes 6144kb to the Chip, if its 6146kb it will flash 6146kb to the chip, it completely avoids the steps that Asus EZFlash and Winflash would take to retain your original Windows 8 Key or Laptop Serial Number, so this is what causes the Brick and when you brick with FTK, there is no way to recover unless you replace motherboard or BIOS CHIP. Asus EZFlash and Winflash seems to only flash 6144kb to the BIOS chip whether the file is 6146kb or not, it only flashes 6144kb to the Chip (it does something I don't know lol) Its confusing to explain but I hope someone gets it.

Do not flash using the Bios prema uploaded, you will brick. Please follow my guide on overclock.net search my username and the thread should be under laptops and mobile computing category. At this moment you must only modify your own backup bios to keep your laptop serial number and windows 8 keys. FTK does work but if it gives you any warnings about size mismatch, do not flash, you will brick.

Sorry I got back to this kinda late, I made quite a lot of progress with this_ I was able to unlock my own BIOS and insert in my own modified GPU vBIOS follow my guide on overclock.net just search my username and find my GTX 670MX modified BIOS thread because I don't think the mods will like me posting links to another forum It'll tell you everything from there and the best part is, All the information I provide is from my own findings and completely free - - - Updated - - - Can't do anything, your bricked for GOOD unless of course you replace BIOS chip or motherboard as whole, if your good with soldering the BIOS chip is easy to replace otherwise you have to send it in for repairs_ DO NOT USE THE G75VW BIOS, it is a completely different BIOS from the G75VX (both models of laptop has different Bios) FPTW64 is not a good idea to use(Always flash from within DOS mode and never from within windows)

Looks like the GPU bios isn't loading_ best shot is to blind flash it. You got to create a bootable usb with and auto execute flash command to flash the original BIOS file into it. Remove your hard drive and remove your DVD/cd drive so the motherboard has no choice but to select the USB stick as a boot up option. I know there's some information about creating an auto execute command to flash on a USB stick to where all you do is plug it in and the auto execute command does the rest.

I had high hopes too, for now everything has to be done via Hex Editor_

I tested it, doesn't work on mobile bios, at least not Kepler.

Thanks Prema, yeah I suppose I'll have to wait on the voltage tables, there seems to be a lot more to it than I expected, or maybe there isn't and I just don't have the correct keys_

Thanks Prema, how can I look into this BIOS? I eventually figured it out and made a BIOS of my own_ including modding the GPU, still trying to figure out how to do the voltages_ I was going to look at this BIOS you uploaded but it requires a password?

I was able to extract the GPU Bios out of the Main Bios, but no editor software out there can mod this BIOS yet, so I'm just waiting to see if they'll eventually add support or if someone can help modify the GPU Bios for me, until then I'm going to look into it the best I can.

Download 11DE11A1.rom from Sendspace.com - send big files the easy way Here's a link to my GPU Bios for an Asus G75VX GTX670MX. If someone could kindly tinker with it to allow me to push higher clocks that would be great!_ I can't get nvidia inspector to work on my laptop(keeps bugging out) I would definitely donate to buy a few beers for your time* =]

Ahhhh OH YEAH!! The sweet smell of SUCCESS! I got it, just can't seem to upload screen shots, but I can now adjust a few good settings like fan control adjustments for active trip points, and I can adjust turbo ratios individually and have the ability to disable hyperthreading and such, pretty sweet_ Took me a while but I knew I would get it to work, now its just about trying to get the chipset tab to appear_ I would load up screen shots but apparently its not letting me at this moment.It was a lot easier than I thought, just needed to find the right tools, now it all goes up from here ! I will share my BIOS file once I get it worked to when I think its proper to release. My last flash was just a test flash to see if what I'm doing will work and apparently what I did work so now I need to go finalize a few things before sharing this BIOS. Now I know how to get it to flash, next stop will be modifying my own Bios for the GTX 670MX, just gotta figure out how to extract the gpu bios out of the bios file since Nvflash won't work on it. Any advice would help if someone is willing to give some.

You probably have more knowledge and skills in this than I do, I usually learn off information I find around the net and I have been quite successful with Phoenix BIOS's and some AMI Bios for OEM motherboards for desktops. If you do end up getting to it that would be awesome, I will be your first willing tester_ For now, I will see what I can come up with if anything at all.

I'm here to report on my progress, today I made a somewhat effort to try and flash my modified BIOS, but no to avail I just can't get any flashing program to work. With AFUWIN, I get error Bios doesn't allow full erase_ With AFUDOS in DOS, it says that its unable to erase rom, using a new program called FTK, it states that it can't get access_ so apparently they locked down these BIOS pretty good_ If I can't flash it, I can't test it... so I'm sorta out of luck here_ Any tips?

[h=2]Asus G75VX Bios (difference between downloaded version and version already on laptop)[/h] Currently I am working on a modified BIOS for my Asus G75VX, I wanted to unlock some overclocking options along with the ability to change ram timings and such(Just because I'm always wanting to push for more) Anyhow, I downloaded the Asus G75VX .204 bios off the website and proceeded to work with it and attempt to unlock a few Hidden BIOS menus, well once I completed it, I went to try and attempt a flash with AFUDOS. Apparently AFUDOS reports back that BIOS Checksum is incorrect. (Now don't get me wrong, I know I modified the BIOS but I made sure the Checksum was the same as the Original unmodified BIOS I had downloaded from the support page) I then decided to make a backup of the Original Already Flashed BIOS on the laptop using [AFUDOS Original.rom /O] as the command to backup existing bios. To my surprise I find out that the Original Bios that is currently on the laptop is only 6144kb(in total size) compare to the Original downloaded BIOS on ASUS's support website which sits at 6146kb(in total size) Odd thing is, both bios is the same version .204 which is current according to Asus support page. CPU-Z and HW64Info reports that my current BIOS is .204_ I am still confused about why there is a BIOS size difference between these two BIOS the one downloaded on Asus support page and the one currently on the laptop considering they are both the same BIOS versions (204) In theory, I'm guessing this is the reason why I've been seeing a lot of BIOS update failures lately from other owners of the same laptop(It might be due to this checksum error) But who knows? Anyhow, I'm currently working on a Modified/Unlocked Version of my Asus G75vx 204 bios that I got from backing it up via AFUDOS. I tried flashing it but apparently AFUDOS reports back that there was an error in deleting the old bios but Checksum is correct. SO I am making some progress with my BIOS modifications.. just really slow. Just thought I would share my findings. Thank you. It would be nice if my attempts actually work without me bricking this thing haha, wish me luck_

No one has any input? I guess I'll have to look into modifying this BIOS on my own and see what I can come up with. If anyone has some tips please input.

Go buy some rubbing alcohol from your local store, I recommend at least 97% or the 99 percent rubbing alcohol because it'll take the old thermal paste off much faster and it'll evaporate quicker. I usually get some paper towels, wet them with rubbing alcohol and wipe the old thermal paste off, for small areas and difficult wipe off area, I usually use a Q-tip, Soak it in rubbing alcohol and wipe the old thermal paste off. Let it dry(Takes a few seconds) then re-apply thermal paste as needed (usually a tiny pea size dot in the middle of the GPU/CPU is fine and good enough.

I have looked everywhere to see if I can find someone who has an Asus G75VX Bios that has all the options unlocked for some overclocking/tweaking capabilities. It's been such a long while since I've done any BIOS Mods and my knowledge is quite low on these new AMI Bios If someone would please kindly look into unlocking/modding an Asus G75VX laptop BIOS for me that would be awesome. Here's the link to download the BIOS ASUS - - ASUS G75VX It seems this laptop is quite new, so many users haven't been around to modding it yet. I've heard that if you just change everything in the BIOS with AMIBCP 4.53 from Default to USER, you might be able to access it, but I am completely unsure about this and if someone with more knowledge can input it would be great, if someone can modify a BIOS for me, I am more than willing to be a TESTER to try and flash it, I understand the risk but am still willing to do it for the sake of the modding community.
