@Lost_N_BIOS I believe the DMI reported max DRAM size is fake.
Just try 32GB *2 first, and see what happen.

@dsanke - I thought that, and suggested it as well, and maybe thought I found maybe I found memory limits (lack of) in SiInitPreMemFsp @ routine 6FABF, but not sure at all.

I was thinking, could the reason i couldn't get above 2666mhz with my ram. Is it because of my Cpu? Cause my laptop is running an i5 9300h so could it be the cpu doesn't allow a higher memory speed?

@Lost_N_BIOS

Actually Acer says the RAM expansion limits are 32GB but Intel says the CPU limitation are 128GB.

So I thought it could be something set in BIOS.

I didn`t try to use 64GB or more yet, the RAM is a quit expansive.

Would be great to know if someone had tried to use more RAM than Acer says as the limit.

@moonzz Yeah, H without K usually have IMC locked.

@dsanke Thing is I've seen people with I7-8750h and 9750h overclock their rams with the unlocked bioses to 3200+MHZ. So I was wondering whether its a limitation of the i5 variant that doesnt allow an increase in memory speeds

@saltinbank - What CPU model do you have?

Hi @Lost_N_BIOS

i appreciate your work and would ask, if i could get an unlocked Bios for my Acer Predator 317-53, too. I'm new to this kind of stuff, so please don't blame me :-D And sorry in advance for the bad english of mine and the questions i may have .... :-)
The link to the bios downloadpage is h t t p s : / /w w w.acer .com/ac/de/DE/content/support-product/8051?b=1 there is always a space between the first few letters and 3 spaces between acer and .com, because the forum didn't let me post the complete link, not enough posts .... .

My vars are attached below, it worked in 3 files.

Thanks in advance and have a nice day

Regards

@Lost_N_BIOS Thanks for your quick response, i will wait then, thank you very much !!

@DaFeu - You're welcome! Please see my edit above, your upload was not correct

@Lost_N_BIOS here the new link, hope everything ist ok now s000.tinyupload.com/?file_id=02094982249567218857

Thanks - you can post links now
OK, please refresh this page in about 2-3 minutes, I will edit in here next step for you

* Edit - @DaFeu - Please drop this modified vars into H2OUVE_100.0.9.2 folder, then run this command >> H2OUVE.exe -sv varsM.txt
There will be long list of success/fail, reboot once that is done.

Then do step #1 of spoiler below and send me the file. I will edit this and send back to you in minute or two, then you will flash it back using step #2 and the new file name (I will rename too, so you know it's mod file)
Use a new file name, if you have biosreg.bin in your FPT folder from earlier, use new name like biosregnew.bin
