Acer Predator Helios 300 PH315-53 with RTX 2070 Max-q bios unlock help required from @Lost_N_BIOS.
Have read a previous post for the 52 model tried reflashing the bios (extracted from my laptop) using ME tools and its write protected so I have attached the vars text file in the zip you have provided .
Eagerly waiting for your reply !
Thanks in advance !
H20UVE.zip- http://s000.tinyupload.com/index.php?file_id=71961397107769458305
Original Bios v1.11 just for reference.
@karthikdgr8
Please put the modified vars below into H20UVE_100.00.16.08 folder, then write back the mod vars using this command >> H2OUVE.exe -sv varsM.txt
http://s000.tinyupload.com/index.php?fil…133234898061446
There will be long list of success/fail, this is expected, reboot and then >>
Once you do this, reboot back to windows, and make a NEW biosreg dump, using new name (or toss older one) Then send to me
@karthikdgr8 - Here is your unlocked BIOS

*** WARNING - To ANYONE with laptop and unlocked BIOS!!!
DO NOT try to enable this graphics card or disable that card, switch cards etc. Otherwise you will end up with no display output (ie black screen) and no way to recover except by blind flash or with flash programmer.
You can change graphics related settings, like changing memory sizes, or core speeds etc, just don’t try to disable one card or change which is main etc.
Additionally, be very careful when trying to undervolt CPU, you can leave BIOS unbootable due to CPU voltage too low (Sometimes even 0.05 is too much)
WARNING *** - This BIOS is user specific! If you are not user karthikdgr8 at Win-RAID.com forum, DO NOT USE THIS BIOS!!
If you do, and you are not karthikdgr8, then you will loose your serial, UUID, OG NVRAM, and possibly LAN MAC ID as well.
You have been warned!!!
The bios is unlocked, thanks ! But I am unable to find XMP option . The overclocking feature is disabled and greyed out . Is XMP under overclocking ? @Lost_N_BIOS
@karthikdgr8 - Sorry, I may have forgot to unsuppress a submenu, if so I will get it for you tonight in about 5-6 hours from now. Can you see >> Advanced >> OverClocking Performance Menu?
XMP will only show up at "Memory profile" Option if your memory has XMP profiles, you can check/confirm that with HWINFO64
Yes my RAM has XMP profiles upto 3200C16 and the overclocking portion of Advanced menu is Disabled and greyed out . And the memory section has maximum memory frequency . No XMP option and I cannot see any of the options seen in the screenshot which I captured from another users post . I cannot manually change timings or choose a memory profile . @Lost_N_BIOS
@karthikdgr8 - That grayed out area at top is supposed to be that way, it’s text readout of SPD/XMP data to show you info. Looks like the XMP profiles are not compatible with this system, since all that XMP is zeros.
Please run HWINFO64, in the large window click report icon, then HTMl or txt, then uncheck everything except memory, and send me the report << Ignore this, for now, I thought those were your images is why I wanted to see this
Where you see “Custom Profile” in bottom image, that setting is where you choose Auto, Custom, or XMP1/XMP2
Ohh wait, those are not your images?? Very confusing here, show me images of your BIOS. Can you see >> Advanced >> OverClocking Performance Menu? If yes, show me image, even if it’s greyed out, so I can see what you see before I make edit
No, sorry for the confusion ,the image is from another user . My bios images are attached . I cannot use the overclocking feature as it’s greyed out . @Lost_N_BIOS
http://s000.tinyupload.com/index.php?file_id=17922355537838647316 @Lost_N_BIOS Also can you check if any battery charging parameters can be exposed . My system keeps draining battery even when plugged in under heavy loads as it is designed in such a way according to Acer . I would like to tweak some settings to prevent this if possible . Thanks !
@karthikdgr8 - It’s probably designed that way so when under heavy load all the power is not coming in from single source, less heat and stress on the board that way. I will see if I can find anything battery/charge related and let you know.
Here, now enable Overclocking Feature, and let me know if you can then see the memory menu inside there (reboot may be needed after enable overclock feature, not sure)

I see this, but I think it’s about when to always start to charge battery >>

If either of those sound like what you may want to try/test changing, and you can’t see them, let me know.

@karthikdgr8 - Great to hear it, and you’re welcome! So, you can access memory section in there now too, correct?
That’s correct .
Nice! 
Now, be careful, pay attention to what I mentioned in the warning above
Hi Lost_N_Bios
I have the same situation as karthikdgr8. I need to unlock this Bios in order to recognise properly the real ram frequency. Why Acer installed Samsung ram at 3200MHz but on specifications box label it is written 2933 ? … I mean, i just installed another SSD but suddenly i checked the ram and it’s not 2933 but it is at 3200MHz… I know that the cpu cannot support 3200MHz but the memory controller can handle… I did an upgrade to an iMac which supported max 1600MHz according to Apple but suddenly i installed Hyperx at 1866 Mhz and what… It was recognised by the system, it was stable and of course better benchmark score than others with the same model of CPU but lower ram frequency just because of Apple restrictions. Same thing was for my ex laptop Asus ROG, i had 1600MHz stock ram frequency just because of limitation of 4750HQ cpu then i installed Hyperx at 1866MHz. During benchmark test i got a better score and also the bios recognised the new ram frequency… My bios version from this Predator is 1.09. Could you help me to unlock this bios? Thank you
