Lets enable overclocking on all 6 and 7 series laptops

I opened up your firmware you linked and it is not in a flash image format. You need to dump the firmware off of your system for a full image.

Hey,

I was trying to figure out Nando's post, where he quoted you (here). Looking at the already modified ME9 FW in FITC (linked on Nando's post), and comparing it to mine in ME10 FITC, I couldn't deduce which setting enabled all of registers after EOP. Could you tell me specifically what I would have to change to enable all the clocks, thus allowing me to slightly increase BCLK via XTU?

Here's two quick FITC side by side comparisons, with mine on the left (ME10), and ME9 FITC on the right,

The size mismatch is fine when flashing.

This is the modded bios kindly provided by Khenglish from a HP Probook 6470b with an HM76 chipset. It is not my laptop anymore but I could try your mod since my friend gave it to me to perform a cleanup. Could you pls walk me through what I should change to test if your theory works with HM76? Link for the original bios here.

Theory is an overstatement; changing the ICC boot profile to be selected by BIOS instead of the default "soft strap" enabled BCLK access via XTU on an HM77 chipset. I just figured since it was the only additional change necessary to enable it on that specific HM77 mobo, and that this is something I have not tried on HM76 then it might be what's preventing XTU access/capability to change BCLK.

Step by step, explain-it-to-me-like-im-seven:

  1. Click and drag your ME FW onto FITC.exe
  2. Under the subsection Descriptor Map, change Number of Flash Component to zero so that only your ME FW is built/compiled
  3. Under the subsection PCH Straps -> PCH Strap 10, change the third parameter from the bottom ICC Boot Profile Selected [...] from true to false
  4. Done.

Or, you can just flash this, which I already modded. I used your stock BIOS, added the changes from the OP, and then did ^. End result is your full BIOS image.

Will be trying this as soon as I get home.

EDIT : not working. Seems like BCLK OC is not for HM76...

Thanks for the update. TBH, it was a long-shot wild guess.

How to unlock ICC Registers with Clock Commander Tool?

For ME8, you can issue the cct sl command. This has to be done before "EOP." In my experience, unless you have a programmer and you're using it in conjunction with the Clock Commander Tool, enabling all ICC registers this way is a dead end because issuing that command before EOP is impossible or unknown. Alternatively, you can enable all/most ICC registers via FITC.

Hey!

I'm new on this forum. And now i found this thing. And It could be helpful for me because last days I set up an eGPU and I think I have a huge CPU limit with this 2520M. So if somebody can help me to found the way how to tweak my latop, that would be great.

My spec:

Hp Probook 6560b(HM65)

8gb

2520M

+eGPU

Try the keyboard sequence for HP systems on the first page and get an image dump.

Okay. Now I think I got my dump file. Here is mine: Hp Probook 6560B

As I said I have an eGPU set up, so if you could modify for me that bandwidth, that would be the safest way for me. Can you set my cpu to oc over 3.5-3.6Ghz or higher with turbo? And what about undervolting/overvolting? Can you do that? I have a 90W PSU. I dont know does it matter anything?

I want to juice the max from this config, but Im new in this area. So sorry because of my noob questions.

Now I think I bricked my laptop. It doesnt boot up. Just turn on for a moment and shut down. Are there any method to get back? I cant reach the bios.

I did this before:

Open your ocme.bin with FTIC

Open the extracted folder named ocme

Moved only the me.bin part to fpt windows64

Cmd run as admin. And run the fptw64 program with this flag: fptw64 -me -f me.bin

After that i cant boot up.

UPDATE: Now I can boot up with the keyboard sequence but only with them.

Interesting findings regarding how to unlock the ME Firmware region on Ivy Bridge (and maybe SandyBridge and Haswell) Latitudes

@ http://forum.techinferno.com/dell-latitude-vostro-precision/9690-14-dell-latitude-e6430-performance-upgrades-system-mods-14.html#post140069.

There is a UEFI variable which temporarily allows ME Firmware Image Re-Flash. Maybe such UEFI variable in other notebook BIOSes too?

What did you do that bricked it?

Just flashed your ME FW. After that I was able to boot only with the keyboard sequence. But after I changed the 8gb ram to 2*4gb it worked.

But bclk in Intel xtu is inactive.

My ME FW? I never made a ME FW for an HM65 system. If you flashed one I made then it was for another system.

Why not make the CPUs full unlocked (no limits on bins) than mess with a puny bclk percentage?

Disclaimer: I don't know of any instances where this has caused a brick, but that doesn't mean it won't happen. I'm highly doubtful of this method's potential for bricking a laptop. In the event it does, just do a regular BIOS recovery using stock bios. dont blame me for anything !

Here's a short how-to for unlocking the flash descriptor on most laptops where the bios that is not encrypted, regardless of manufacturer. All you will need is a hex editor, your FULL bios image, and know how to perform BIOS recovery.

  1. Obtain/download a copy of your stock bios. Doesn't have to be stock, but just to be safe.
  2. Extract it to a folder (if it's not already), and open the bios image in a hex editor,
  3. Search for these bits,
    5A A5 F0 0F 03 00 04


  4. If you're in the right spot, 5 lines below that should be where your flash descriptor's lock is set. The block of hex bits for the desc region should look something like this,
  5. Untitled_zpssxi4fc2q.png
  6. Save it somewhere.
  7. Perform BIOS recovery using your newly modified bios, afterwards you should have ME r/w access.
  8. (if required) re-install using the latest IMEI drivers.

The reason you can't just flash this as you normally would when updating BIOS is because ME region does not get updated during typical BIOS updates, only the BIOS region does. When you do recovery, it flashes all available regions, including ME.

Hello,

Is this mod going to work on Asus g75vw? I have a i7-3610qm. Will I be able to overclock it?

Thanks

Whoa, nice info!
I stumble up on a supposedly full 8MB BIOS dump from a Chinese website that states it's for the G46VW.

This 8MB BIOS actually contained: 5A A5 F0 0F 03 00 04

Further down (as expected) it also contained: 00 00 0B 0A 00 00 0D 0C 18 01 08 08

 

Q: Since I'm not really sure if this BIOS is safe to flash, how can I examine it to be (more) sure, maybe someone with more experience could have a look at it?
@Khenglish @Klem @timohour @Tech Inferno Fan @ModJPB @blowntaha

I'll have to admit I'm a bit exited now!

 

8MB BIOS (my dropbox)

6MB BIOS V210 (ASUS)

 

EDIT1:

I've now compared the 8MB BIOS with the latest official G46VW v210 BIOS, the BIOS share a lot of common parts. I don't know how to go from there, my investigations are purely speculative.

 

EDIT2:

I guess pulling the 2MB ME part of the full dump (ME seem to be 2MB of the beginning of the file) and concat it to an official ASUS BIOS would an idea?

I have the ability to flash my ME firmware, I've updated to the latest version using the bios-mods website files and tool kits.  I am attempting to set the overclocking profile to turned on rather than standard which maxes BCLK out at 100mhz in XTU and cannot be upped.  I want to gain control over this to attempt to get a slight overclock on my Dell Inspiron with i5 6300HQ.  


Can anyone guide me on how to complete this?  I've been attempting to mod with FIT but cannot build an image.  I think what I need is my actual ME firmware from my own laptop, but for some reason cannot extract this and get it to load in FIT.  Anyone?

Your system is Skylake based. The tools here can only work for Sandy Bridge and Ivy Bridge systems

 I'd love to hear some input on my previous post. The 8MB BIOS dump is very very rare to find for my system afaik. I'd need some guidance, maybe I could include the ME region of the 8MB BIOS in the official 6MB BIOS?
