Manually unlock a processor?

I clicked "validate" and nothing happened, does it automatically send? I'm using an old version of CPU-Z. I just use it for clock validation on BSEL mods like on LGA 77x.

 

I also clicked "Bench" and "Submit" but nothing happened either.

 

As far as I can tell each microcode is uniquely parsed for each CPU, so a decryption method for one set of codes won't necessarily work for a different CPU, even if it's the same family.

 

I'm gonna see what I can do with my i5 3470. I have two of them so if I break one there's no loss.

You need an account on hwbot.org and there are more steps like screenshot before you submit. You can just validate CPU-Z, it'll give you a checksum you use on their validation site.

 

Now that is very interesting the code is unique for each chip in family. Do the identical i5s have the same code?

Yeah I'd rather not spend $300 on a new processor

You undervalue your time.  The amount of time this would take, if possible, is not nearly worth $300.

 

Edit: Saw that you made some progress.  Nice work.  Was it worth the effort?

I'm not making an account I'll never use.

 

I don't know if it's unique to each CPU specifically, because they'd need the UID of each chip manufactured, but considering the i5s I have are both the same, I'm guessing "yes".

 

For now I'm gonna keep my multiplier at 37 (where it belongs) to avoid damaging my Xeon, used ones are still $300+ and I got mine for three times less than that.

It took about three months, starting the day I posted this (because of work). I found the unencrypted microcodes easy enough from Intel but they're "packed" in the UEFI. I didn't do the decrypting, someone on /r/crypto helped with that. It's like an archive but in a proprietary format by the MB vendor. Some BIOS utilities and UEFI editors can help, some can't.

 

I used DMEdit to do some digging in AsRock's trunk.

 

The rest can be done in a hex editor as long as you have the info from Intel that states how the codes work and which do what. Which you can only get FROM Intel. I had to email them for about two weeks to get them for my Xeon, and even then I had to assure them I wasn't going to sell the modified microcodes.

 

So yes, it's not worth my time or effort, but the knowledge and experience is nice.

 

Here's the Sandy Bridge pad-out:

That's a good call if they're holding their value 100%.

 

E5-2683v3 are 14c/28t at 3GHz turbo LGA2011v3 chips that go for $399 used. If you could get your hands on that setup and do this it would blow up the CPU market.

[TahoeDust]

Do you have any benchmarks of it running at 4GHz?

I just spent a month's savings on a GTX 1070, maybe when I can afford the MB/CPU/RAM combo I'll take a look, but I'm guessing that the microcodes have been completely rewritten for the new gen of CPUs. Maybe if I win the lottery.

I uninstalled Passmark because the D3D9 test was broken, but I can run the CPU-Z test and post a screen.

 

I'm working on a customer's tablet right now, replying in between steps (screen glass replacement). Right now the screen is on the hot plate.

With all due respect OP, I won't believe anything until I see some rock hard proof (such as CPU-Z validation). 

 

[TahoeDust]

Why don't you run Geekbench or anthing else that produces an online validation link?

Yep.  Looks like more bullshit from a poster that has a history of Bullshit.  Like claiming he can type 250 words per minute...lol.

I've added Xeon microcodes to a factory Dell board, but that was with a guide.

 

So the microcodes dictate whether the multiplier is set? I've locked my E3 1240 at the 37th step multiplier (3.7GHz, which is actually the turbo speed) so it never throttles (always at said speed).

Not even close to editing microcode.  You are just adding already signed microcode to an existing BIOS, not changing the microcode itself.

 

What you propose is like claiming you can hack a server because you can ping it while not really knowing what a ICMP packet is or does.

Not possible. Buy an unlocked processor if you want to overclock (Intel: xxxxK or Extreme Edition, AMD: Everything that has "Ryzen" in it's name and some older ones)

This information is for education purposes only.

 

It is possible just research the processor in question either it is on the market (a little cover for certain pins you attach) if it is in the market you can also just look at which pins are being covered and put a little tape on top to do it ur self cheaper since these pin covers cost 15 to 25 USD. If there is nothing on the market you can just research ur self which pin to cover and do ir manually.

 

to clarify you might lose some other functionality by doin this and you can also just go by trial and error but I don't know how risky that might be for your cpu 

Edit: I want to apologize for Miss informing people apparently in the more recent cpus this does not work since I have rather old hardware I was mistaken that this still works
