Hi @Jimmyme
Yes I was able to unlock the bios setting and underclock. One major advice I would say if you do unlock the bios is to save as user default first in the bios and play around with it afterwards. Its probably got me out of a few headaches my user backup and saves having to load the default backup and start all over again.
With my laptop I could only go -80 for core in the bios, but it only sets the cache offsett. Otherwise it goes to 0 for anything higher and it doesnāt set, which im guessing is due to some safe guards. So I mainly use throttlestop. Currently at x36 for all cores at -180.7 for core offset and -79.1 cpu cache. But as you are starting off , maybe try -50 and see how it goes. I have multiple profiles in throttlestop, as Iāve found a lower turbo ratio gets stable for games which are mainly reliant on the gpu.
Im a beginner myself so its mainly been reading about other forums and trial and error. But go slow and incremental jumps. It might be tempting to reduce it by a lot, but best to avoid that.
is there a way to unlock the bios for the new aero 15 xc laptops?
@rezzy_s thanks so much for your reply and advice!
I might start to try undervolting it tonight - but I am scared of making mistakes with the BIOS flashing!
With your undervolting did you see better temperatures during gaming and normal use?
Thanks again for your help!
@schrumpelrat I guess it will be possible by doing the same steps others have taken:
STEP 1 - dump your current BIOS
STEP 2 - unlock flashing of your current system
STEP 3 - edit the dump of your current BIOS to unlock settings
STEP 4 - flash the new BIOS
Iām a total beginner and am just learning myself so be careful and do your own research!
Sorry to post again in this thread so quickly.
This is the system I want to undervolt:
AERO 15 KB-7JP1130JH
i7-10750H on HM470 chipset
RTX 2060
144hz Panel
These are the steps that I understand that I need to do:
STEP 01 - Install lastest BIOS from manufacturer. Dump BIOS and archive it.
STEP 02 - Provide link to BIOS from manufacturer to @Lost_N_BIOS. (help with variable to unlock BIOS region and unlock BIOS itself)
STEP 03 - Unlock BIOS region with variable from @Lost_N_BIOS.
STEP 04 - flash unlocked BIOS.
Is that correct?
Iām concerned that all the guides and programs are for older models (HM370 chipsets, my model is on a HM470 chipset).
Can I still use to older guides (particularly when unlocking the BIOS region) with my newer model?
@Lost_N_BIOS
Hi! I hope you can help me with my BIOS requests. 
Here are pics showing my current BIOS:

@Lost_N_BIOS
Sorry to bother you again. Is it possible to tell me the variable to unlock my BIOS Region?
Thank you for any help possible!
Hi @Lost_N_BIOS
Sorry to bother you again. I have been reading and researching! I hope to unlock my BIOS now!
Any help you could offer would be much appreciated!
I dumped my BIOS.
It can be found here: http://s000.tinyupload.com/index.php?filā¦329893849923525
Now I will try to unlock BIOS flashing. Can you help me identify the variable that I need to change to unlock the BIOS Region?
Any tips for an AERO 15 KB (no OLED) would be much appreciated!
EDIT: Disregard
@rezzy_s
How did you unlock your BIOS Region? Using RU method?
Also, what was your variable?
Our systems are similar so maybe it can help me.
Thanks!
Iām trying to do a hardware upgrade of my Gigabyte AERO 15 SA (i7-9750H).
In a few words :
- Adding of one new 8 Go RAM module (in addition of the OEM 8 Go ram module) : SAMSUNG SODIMM M471A1K43CB1-CTD
- Adding of a second 1 to SSD M2 NVME (250 Go on the OEM M2) : WD Blue SN550 NVMe SSD 1 To
Tests report :
1) First try :
- Black screen on laptop startup
2) It seems to be a RAM problem, so I giving back RAM to OEM configuration :
- the BIOS seems to go further (GIGABYTE logo on screen), function keys reminder but no OS boot and I canāt access to BIOS setup (F2 key doesnāt workā¦).
3) I giving back SSD slots to OEM configuration
- laptop is working normally (OEM configuration)
I tried with and without Trusted computing enabled.
new ram module and OEM ram module photos in attachment.
Could you help me to solve the problem please ?
Hi!
Iām not an expert with laptops but have some experience with desktops.
Start by just changing one thing first and testing. This will help to find the issue.
First reset you BIOS back to factory defaults and then try changing things.
With the RAM:
Have you tried booting with only the new RAM installed?
If you have problems with just the new 8GB RAM installed then you probably have a bad stick and need to send it back for a replacement.
With the HDD:
Iām really not sure here why this would be happening. Sorry. I hope someone new else can help.
@Jimmyme Yes correct. I had to use the RU method, since the other one didnt work. If you go on page 4 of this thread Lost_N_BIOS mentioned these steps. I think it is is around the #203 reply.
@rezzy_s
Thanks for the reply!
I have prepared for RU method.
I just checked reply #203 in this thread. So you changed this variable: (4570B7F1-ADE8-4943-8DC3-406472842384) at PCHSetup?
Thanks for your help. Our system is same except for OLED display. I think this can work for me too.
Yep correct. But just read a few of the comments on that page about the RU method and you should be good to go.
@rezzy_s Thank you very much for your help. I managed to do it!
BTW, does Windows 10 install BIOS updates automatically on your system?
I think it might do that on mine. Did you disable it somehow?
@Lost_N_BIOS Could you please unlock the menus in my BIOS?
Of course, I would be most happy to donate to you and the site.
Thank you in advance!
I used RU to edit the BIOS. Then dumped it in windows and reflashed it. No errors.
Here is my region unlocked BIOS: (REMOVED)
EDIT: I will remove the BIOS file until I hear something from @Lost_N_BIOS or another user who can help unlock it.
Bumping this for help.
Hello all, found this today searching out temp issues on my Gigabyte Aero 15 2021 version.
Just wondering if this would work on the latest one?
Mine is the AERO 15 KC-8US5130SP
IntelĀ® Coreā¢ i7-10870H,
16GB DDR4-2933 RAM
512GB PCIe SSD
15.6" UHD OLED (3,840 x 2,160)
GeForce RTX 3060 6GB GDDR6
iāve noticed my temps are always high, in a game for instance on a cooling pad in witcher 3 settings on ultra, hair fx off
80 on the CPU and 83 on the gpu, didnt seen any stutter or fps drop below 61ā¦ just wanted to be able to use throttle stop or xtu to drop my cpu tempsā¦ I will be running afterburner to drop the GPU tempsā¦
basically, can the bios be modded to allow cpu adjustmentsā¦ thanks.
Hi @epikhanzen
I guess your system is pretty similar to mine.
Check through this thread to learn the various steps neccesary.
At first it can seem intimidating but soon things get clearer!
Bascially you need to do the following:
- Unlock your BIOS Region for flashing with RU method. (see post #203 for possible variable to change)
- Dump your BIOS and get it unlocked by someone.
- Reflash your BIOS with the new unlocked one.
Good luck!
I have done most of the steps but am only a beginner. And Iām still waiting and hoping someone can unlock my BIOS for me so Iām not even finished doing it yet!
IMHO, these are not temp you need to worry about. Are these max temps you are seeing?
Look in the Control Center first page: what are the fans speeds you are seeing on max setting?
Yes, you can unlock CPU menu options to use ThrottleStop, but I doubt very much youāll be able to bring temps down via undervolt. Keep in mind, finding a stable offset for undervolt may envolve crashes which by nature are unpredictable and have potential for data corruption and other headaches. See my experience I posted here. Good luck!
