Razer BIOS Mods - Potential to Unlock All Hidden Options

I had read since the beginning, but had completely forgotten all those steps since this thread is creeping on being 2 years old now and for quite some time the only method people spoke of what using a ch341a programmer. My apologies, I went back and re-read the OP to see those instructions. Thank you.

 

Let me know if you succeed!

 

So far so good except when I get to the ifr section of the guide, the link provided does not have a windows version of the ifrextractor, only a mac version which I believe will not work in command prompt. Perhaps you can point me in the direction of where you got that file?

Edit: NVM, previous version of that do have a windows file.

 

In case if you need smtg, I've uploaded all tools: https://drive.google.com/drive/folders/1ogId2FNKfJLjGejvrayjhZNHpskNh6hv?usp=sharing

 

You have to change 2 parameters: CFG Lock and Overclocking Lock.

 

Let me get this straight, you claim that we can modify the bios without any flasher or in need to unlock it? Do I got it right?


I have a Razer Blade Base 2020, with BIOS 1.06. So I can unlock it doing it your way? Can you make the step by step guide? I would really really appreciate it!

 

It worked, undervolting is unlocked now. I have a 10th gen which I've read don't undervolt very well, -100mv resulted in a lock up. Testing -85mv now and running 3DMark, and it's running fine so far!

He is not wrong. I just unlocked undervolting in throttlestop!

 

How? I downloaded his tools, can you give a small step guide?

And can I use the included BIOS? I have a RB Basic 2020 with a 2070

 

I will write you a step 2 step guide tomorrow. stay tuned.

 

I will, thanks! Also again, can I used the included BIOS? Or do I need one from my system?

 

I'm glad you did it.

 

Can you maybe give me a simple and short guide? I have downloaded your tools, whats next? Do I need BIOS dumb from my system? I just want the ability back to undervolt.

 

DO NOT use my Bios file. I've already removed. You can use only yours. I'm tired as hell will make guide tomorrow. If you cannot wait just simeply follow CAREFULLY the method I posted earlier.

 

No problem, I have time. I’m just highly interested in the method without any programmer. I just need to find the tool to make a dumb of the bios right?

 

I used the OP on this thread to save my bios to file and the guide Laszlo linked to to get it all done. Honestly the guide could be cleaned up since it's original intent is for Hackintosh, but the major steps needed are there.
Find your CFG lock and Overclock lock address locations, make a bootable usb (can use rufus choose non-booatable MBR & FAT32) and make folder in the USB drive called EFI, and a folder inside that folder named BOOT and copy over the general UEFI shell linked in the guide, and the RU program. Then reboot to bios, turn off secure boot, boot to usb and run RU, locate the address locations from early and change the values to 00, save then quit, back into bios to turn on secure boot and reboot last time into windows and boom.

 

Thanks! Really appreciate it, I dumped the bios from the bios updater for my Razer Blade. Now I will go through the other steps


EDIT: I just followed the steps, the only problem I have is to create a readable file from the UEFITool extraction for CFG LOCK and OVERCLOCKING LOCK. via the CMD I can’t get ifrextract to work, like in the Guide linked before.

 

make sure that cmd is in the right folder, and then just run the command, ifr sec.sct sec.txt

ifr if you renamed it that is.

 

Worked, had the wrong commend. So now I found CFG LOCK and OVERCLOCKING LOCK.

Are those the correct ones I marked, and all I have to do is to change both values to 00?

 

Yes, those are the correct address locations for you.

 

Okay and now I have to change those values to 00 RU.EFI tool via the stick?

 

yup, but remember to boot into bios first and turn off secure boot, then reboot again and press f12 to boot from usb drive.

 

I did turned it off, testing it now!

 

So I have the next small problem here. The stick won't boot the Shell-file. I select the stick in the Boot menu and it reopens almost instanty.


I created like you said a non bootable stick with MBR & FAT32 format, then I copied all the files into the BOOT folder on the stick. EFI>BOOT. Downloaded the Shell file from the linked guide, renamed it to BootX64 like in the guide but nothing.


EDIT: fixed it now I’m into shell

 

The last problem I have is how to direct to that adress? By finding the hex or block?

 

It works

I'm able to undervolt it now.

Thanks a lot!!!

 

Can you maybe explain how I can find the adress for Overclocking Lock? I got the CFG LOCK line and changed it to 00 now I can’t find the other one.

 

What's the hex value that you got?

 

I did it, sometimes I’m just small minded. Finally unlocked my blade! Thank you guys so much!

 

awesome, congrats.

 

kool, ZeroBarriart just did a nice overview, i think there is no need for guide thanks.

 

Atm I’m testing -0,140mv so far so good.


Can anyone confirm that, unlocking the CPU voltage actual works? I’m using Throttlestop (also on my older blade before) I’m at -0,190mv at the moment withour problems, I read often that the 10th gen isn’t good in terms of undervolting and people mostly can fo as high as -100mv, I have my doubts that I can legit pull almost -0,200mv without bluescreens. And yes I save the settings to be active.

 

Like I feared, I think the unlock isn’t real? Or I did something wrong. Throttlestop is unlocked but Intel Xtreme Utility is not. Also even when putting a -0,250mv offset I can’t see any changes in the Vcore curve so far. No Bluescreen, not even better benchmarks results like I had back then when doing a uv.

I changed both hex codes to 00. Throttlestop is unlocked but I feel like it doesn’t do anything.

EDIT: Did I miss something? Even a offset of -0,500mv does nothing. Still same Vcore.

EDIT2: I double checked everything went back to Ru.efi but still both values on 00, I just edited both hex numbers from 01 to 00. Throttlestop is now able to change the Vcore etc but even after pressing save, nothing changes. The Intel Xtreme Utility is still locked and unable to change anything. Even changing the Turbo clocks for the cores does nothing. I changed the all core clock to 45 to test it, nothing. I even put a -0.500mv offset on, nothing no Bluescreen or better temps, Vcore curve is the same.

I really hope I just did something wrong. Has someone proof and actual success in changing the Vcore and saw a lower curve? Or even a bluescreen for a too low Vcore? Do I have to trick Razer Synapse or something, to get actual control over the Vcore?

 

Working with MezZo_Mix, and we're getting it sorted. Remember when undervolting you should apply the undervolt too all the chip; core, cache, unslice, etc.

 

I found the solution, first off what confused me the most was, with my old blade I just had to click on CPU Core, on the FIVR control panel and could apply the offset.

now I found what freaked me out. On the FIVR Control Panel, I have to select System Agent and apply there the offset. Now anything over 0,85v will crash.

 

I thought System Agent is something else, it isn't related directly to the CPU. I read somewhere that it is more of PCIe bus controller and memory bus.

 

I don’t know ether, but applying a offset anywhere else does nothing. Even -0,500 on ThrottleStop does nothing.
Other people put on a .0,125mv and get a crash I can’t create a crash on purpose even with 1,000mv uv. And it’s not like im using Throttlestop the first time.

but yes you’re right it’s not cpu related. I feel like a retard, I built computers for my whole life and Overclocking etc isn’t new for me. But how the settings in ThrottleStop affection nothing is freaking me out.

i will test it again. I will set on both cpu and cache a offset of -0,100mv and watch everything again,


Edit; so this time I set a offset of -0,125 on the Core and Cache. Nothing, I even can’t bring the laptop to a bluescreen. I even set -0,500 to core and cache, nothing. The only way to get a crash is when I apply -0,100 on System Agent.

I mean why has this be to be so complicated? On my older blade all I needed was just to apply -0,125 on the core and that’s it, more than that gave me a bluescreen. But with this blade there is nothing.

 

After countless tries. It finally works. I don’t know why it suddenly works but now, any thing higher than -110 as a offset will cause a crash. Also my clock while gaming rises from a average of 3,5-3,7GHz to like 3,9-4,2GHz. Which gave me a good 15% performance boost in benchmarks. The last step I’m about to to is apply LM.

 

Does XTU work for you? Mine is not, it is only available in Throttlestop

Nope XTU is still locked. Which is sad because the program is far nicer to handle than Throttlestop

 

Haha seems like I’m having the same issue as you. UV did nothing. Any tips on how to get it going?

Edit: maybe it is. I’m not sure, cinebench basically has the same score 9736(UV) vs 9735

i would try to shutdown the laptop entirely wait 10 secs and then start it. Open ThrottlesStop, give cache and core a offset, it doesn’t have to be the same.

the easiest way to see if it works is, start a game, watch the clock while you just stand at one spot and change the offset. If it works, your clock should go higher, the higher your offset is.

 

Unlocked and working!

Just wanted to say thank you!

Blade Pro 17 Mid 2021 (11800H - RTX 3070 - QHD) here. The Blade came with 1.03 which was unlocked from the beginning but after updating to 1.04 (fixes type-C display output in dGPU mode) yesterday, the unlock was gone. Took me a while to unlock it again, but its working! (-125mV instant crash @gaming for the test if its truly working)

THANK YOU!

 

In theory it could work to turn off Bios flash protection, which would make possible to flash BIOS back without hardware programmer. All hidden menus could be revealed with an edited Bios file. I wouldnt try it becuase i dont have hardware programmer if anything goes wrong. Someone should try it out who has progammer and experienced with Bios file editing.

 

I have unlocked Bios 1.06 (by HW programmer).
For some reason only XTU ver. 6.5.2.40 works fine with UV. Maybe you have the same issue.

RBA, 10875h, 2070 super. Early 2020 version.

 

Is there an option to remove/change PL1 power limit by editing Bios settings via RU.efi?


I was able to unlocked my RB15 base 2020 via v2.efi and ru.efi but i still have power limit set to 45W. Long CPU test give me only 3.66GHz even if i undervolt CPU Core -125mv and CPU cache -85mv

 

Had anyone here success, unlocking the Memory overclocking menu via the RU.efi hex editor? I just can find the needed menu to get to the hex number.


I just can't find the needed category on the Ru.Efi editor.

 

After completing this guide will you be able to use Intel XTU and/or ThrottleStop on your Razer Blade 2020 model as if it was running on BIOS v1.01 where UV is enabled by default? Basically, Im not interested in any advanced overclocking and pushing the limits, I just want to get control over my Razer Blade.

 

For me just ThrottleStop works, XTU is still locked. Overclocking is not possible, and any turbo clock change on the 10th be will be ignored.

 

Did you go through the entire process described in the first post or is it possible to just unlock the Overclocking section in BIOS?

 

Which blade do you have? And which bios version?
