Here is vars.txt module amd cbs where this setting is stored http://s000.tinyupload.com/index.php?fil...883456942959884

@Lost_N_BIOS help me please! thanks!!
------------------------------

is it possible?
------------------------

@Lost_N_BIOS

What is the exact full model of this system? It does not show on that download page, so not downloading anything yet
Once you let me know, then I will grab BIOS and see what can be done here.

Do you have flash programmer? If not, please test and see if you can dump and flash BIOS via the method shown at end of post #1 in the "Annex" area of this thread
[Guide] How to flash a modded AMI UEFI BIOS

* Edit - Also, please don't make multiple posts in a row, if you need to add more info, questions etc, please use edit button if no one has replied yet.
Thanks

Test method I mentioned, if that does not work, then you might need flash programmer.
When you flash the BIOS on this, or in CPU-z Motherboard tab, do you see FH50P or FH50Q

Sorry, I can't comment more now, it seems like Acer site is messed up right now, can't choose OS Type, or download BIOS from the page you linked me to, aside from not showing model
I tried two browsers. Once I can grab that BIOS, to see if it's same I already have here, I can advise further
You may be able to change settings via RU method without programmer, but I need stock BIOS first (From that page, that I download from there), and we need to know which BIOS from the exe your system uses

Here is RU method guide - Go to section 2.2 and make bootable USB with RU program, then read 2.3-2.5
http://forum.notebookreview.com/threads/...-issues.812372/

However, that guide shows you how to change something in "Setup" you wont be doing the change there, you will make change in "AMDSetup" GUID >> 3A997502-647A-4C82-998E-52EF9486A247

Go to offset 0x93 (93-96) (May be 0093), if default is now 2GB then you should see 0x93 set to either FF FF FF FF (Auto) or 00 08 00 00 00 (2GB)
You want to set this (93-96) to 00 02 00 00 = 512MB

Show me that page, sounds like wrong area or wrong offset, or you do not have Secure Boot disabled.
I never mentioned 0xD0???? You're going to brick the BIOS, don't make changes when you don't know what exactly you're changing!

I gave the correct change value above for 512MB, 02 is part of that yes, but it's not at 0xD0 (nothing here is) and it's a 32bit value taking four spaces that need to be changed (some may not need changed, if already 00)

Ohh!!! Sorry, you are 100% correct! I looked up at question ID instead of varoffset when I was typing out that info for you!! OMG, sorry!

All is correct that I mentioned, except for >> 93-96 >> Should have been D4-D7 Sorry about that, and I just told you to be careful

Go to offset 0xD4 (D4-D7) (May be 00D4), if default is now 2GB then you should see 0xD4-D7 set to either FF FF FF FF (Auto) or 00 08 00 00 00 (2GB)
You want to set this (D4-D7) to 00 02 00 00 = 512MB

If you see 03's as you mentioned, then it may not be correct varstore you are in, or secure boot enabled etc, show me image

The offset for 0xD4 is not the only one that this setting fills, it's 4 bytes in total length as I mentioned
0xD4 - 0xD7 >> If >> FF FF FF FF (Auto) or 00 08 00 00 00 (2GB) >> Change to >> 00 02 00 00 = 512MB



Wow, if you send anymore images, please resize to 800-1000px wide, thanks
If you get flash programmer, I can unlock menu for you, 2nd full advanced and power menu (plus anything hidden in default menus), but I can't make CBS visible

Maybe it can be flashed via crisis mode, I'm not sure, have you flashed mod BIOS that way yet?
If yes, let me know, then make change above first, then dump BIOS and I will edit that to unlock the menus, that way this change already in there (or I can do this edit too if you need)
