@Lost_N_BIOS Alright , I'll try disabling the FD later from the Bios that you gave me earlier .
and as of the edit "overclocking feature" its unlocked and I understand the edits now .
I'll try to enable anything grey if I see any , with that post/method you explained above and post the results !! hope I don't brick again .
thankyou so much again !!

Un-Suppress/Gray is done same way, but sometimes it varies how exactly it's done (like some will have multiple items you need to FF in same instance)
Example
Suppress If {0A 82}
QuestionId: 0x45E equals value in list (0x2, 0x3) {14 8A 5E 04 02 00 02 00 03 00} << This needs 2 + 3 FF'd

Most of this BIOS is like that, other BIOS have other similar things to be changed in same ways, but not always exactly same location for the controlling byte you edit

Yes, if you want to unlock the FD, program in that one BIOS I sent you, then reflash via FPT this latest BIOS region after that, then you'll be back where you are now but with unlocked FD in there

@Lost_N_BIOS hello again .
Memory Profile - DEFAULT , CUSTOM - only these two are present in my tab .
and when I checked the extracted IFR from bios , I can see two extra option "XMP1" and "XMP2"
do you think we can unlock them ? thankyou !

here's the code from advanced-overclocking-memory overclock-memory profile

XMP usually will appear only if your memory has XMP profiles, you can check this in HWINFO64 in the little CPU-z like window and in left side, memory, select a stick, scroll down and look for XMP, also with CPU-z in SPD tab, AIDA64 (similar to HWINFO64) etc. I assume your memory doesn't have or you would see
I use UEFITool version 25, don't use 26-27 in case it breaks your BIOS. Always be sure you replace same way you extracted too (as-is or body)
Yes, same as before for those two items. But if your memory has no XMP profiles you can't use them anyway.
Thanks for images, I only popped in for a second, will be back tonight

@Lost_N_BIOS hey

yea , I'm using two different memory modules .

Just updated my bios to v1.25 and unlocked all the above using your edits !!
I think the problem before was UEFItool 55 .
I even enabled the AHCI/RST mode that they supressed/greyed in the new bios .

@mesh17 - UEFITool 5x is Alpha NE branch, only for inspecting and extracting etc. I extract with 51, edit/insert/replace with 25
For the XMP, if one module does not have XMP, then it may be the one the BIOS is selecting to decide to show you XMP or not, swap them and see if XMP then show up.
If not, you can force it visible, but with mixed modules and one not having XMP, I'm not sure the outcome of selecting/enabling it generally.

So, how's progress been going? Have you been comparing BIOS images vs IFR or BIOS and unlocking the rest, or do you still want me to do that?

@Lost_N_BIOS yea I did ungrey the XMP1 & 2 , but I don't think my modules support XMP as they are inbuilt memory profiles , the laptop just hangs if I boot it ! Or maybe my laptop/Bios just doesn't support overclocking
I can buy new XMP enabled modules as they are pretty cheap in my country . But what if it doesn't work ? It would be a problem as I already have 2x8gb 2666mhz

I'll work on comparing IFR/hex tomorrow as its 2 days off for me , and I'll let you know the progress or if I get stuck somewhere .
thankyou for your help :)

XMP is not overclocking generally, but it is possible, if your memory has XMP, that your CPU wont run the memory speeds that is programmed into the XMP.
You can see if memory has XMP with HWINFO64, CPU-z, check and see. If you need me to show you how/where in images, let me know.
What do you mean "inbuilt" memory? If they are soldered to the board, then you can't swap in new memory. If they are soldered into board, it still may have XMP, you have to check how I mentioned.
And look in both, because if too many SPD profiles then that is all you will see at CPU-z, so you have to also check in HWINFO64 to be 100% sure

Good luck on the editing process

@Lost_N_BIOS Can you show me how XMP looks on hwinfo64 ? No my memory modules are not soldered , one's form Kingston and other form sk-hynix or something .
also do I need to edit more stuff in other region like you explained in this predator thread/post#62 - ( [Help] Unlock advanced menu on 2019 Acer Predator Helios 300 PH315-52 (5) )

You can see it in two places in HWINFO64, when there is XMP profile in the memory. SK-Hynix may not have XMP, especially if not "branded" by some company, but the Kingston one may have XMP, depending on it's original price and what lineup it comes from.
You'll need to select both sticks one by one and check in the large window, same in the little window above the size and and speed, directly under "Memory Config" you can select module too


Not sure what you are asking about editing, in other region? Do you mean about NVRAM? If yes, no, you don't need to do any of that. We did that edit for something he was wanting to hard change the default for.

Test your memory with only one stick at a time installed into slot one. Then see if XMP will boot with either one, if it does, and you see speed or timing change in CPU-z memory tab, then you know one has XMP and it works
Then leave that stick there and install second one, if it then fails to boot, you know that stick can't run whatever speed/timing the first one applied via XMP

@Lost_N_BIOS hello again .
Just updated my BIOS to newer v1.27 ( Had issues with setting Vcore+ setting , but acer just released a new bios with this fix)
the issue comes when using vars.txt - here's the file (first I flashed the new bios - created a new vars1.27.txt - edited it for FPRR unlock - flashed it) my laptop won't start then , I only edited the FPRR variable . - http://s000.tinyupload.com/index.php?fil...933321021087251

I then unlocked all the advanced , power , overclocking at the bios level , so FPT flashing is not available .
Can you help unlock FPRR, bios lock at the bios level ?
Also can you Fix my FD too as this is the new bios .
here's the new bios file from programmer - http://s000.tinyupload.com/index.php?fil...397113791140914
thankyou .

EDIT- Got it disabled :)

@mesh17 - so, is it bricked, or not? It's not clear what you mean, after you said you edited and reflashed mod vars it wouldn't start, so this means bricked or you recovered it?
Ohh, I didn't see the end! So you have programmer, and have sorted all this out now? if yes, great work

I have nitro 5 an517-51 i7 9750h i am also having the same bios chip i just wanna know do you have to remove entire mobo to have access to the chip

Hi

I have the very same laptop as OP, an Acer Nitro 7 AN715-51.

I am currently on latest manufacture provided BIOS 1.29, originally had lower version but I had updated on the hope I would get more options.

So which file can I use and how to flash, please guide me once as I am new to unofficial BIOS but have flashed many Android phones.

Regards.

Hi.

Firstly, please pardon me if you see that some detail is incomplete or I have not yet included any info/image/ss one would need to assist me further. Just let me know if any such thing is needed and I will give a prompt reply.

NOW THE MAIN THREAD -

Current Bios version - 1.29 .
System Manufacturer: Acer
System Model: Nitro AN715-51
Processor: Intel(R) Core(TM) i5-9300H CPU @ 2.40GHz (8 CPUs), ~2.4GHz
Memory: 8192MB RAM
Card name: UHD630 + NVIDIA GeForce GTX 1660 Ti

Most of the options are hidden and/or locked in the new Bios.

Online search reveals possibility of my BIOS containing overclocking, power tweaking and other menus and unlocking the option to boot in legacy mode, as I cannot install the specific Ubuntu I need to without that.
