Asus ROG GL502VS Unlock Request
#61
Guide is in post #27 on page 3, you need to name the efi file you put on USB >> Shell.efi
IFR file is posted on page 5, post #42, this has all the settings and their variables you use in grub / setup_var

This is in reply to BuP4Uk for anyone reading in the future, for GL502VSK system

Core Voltage Mode - Selects between Adaptive and Override Voltage modes. In Override Mode the voltage selected will be applied over all operating frequencies. In Adaptive Mode the voltage is interpolated only in turbo mode.

Core Voltage Mode, VarStoreInfo (VarOffset/VarName): 0x660
One Of Option: Adaptive, Value (8 bit): 0x0 [b](default)[b] {09 07 1A 13 30 00 00}
One Of Option: Override, Value (8 bit): 0x1 {09 07 1B 13 00 00 01}

Change via >> Setup_var 0x660 0x1 / Or Setup_var 0x660 0x0


Core Voltage Offset - Specifies the Offset Voltage applied to the IA Core domain. This voltage is specified in millivolts. Uses Mailbox MSR 0x150, cmd 0x11. Range -500 to 500 mV - see following setting after this one below, set that negative first/at same time, then set your desired negative voltage hex value here. Here is some hex values - http://online.sfsu.edu/chrism/hexval.html

Core Voltage Offset, VarStoreInfo (VarOffset/VarName): 0x663
Default: DefaultId: 0x0, Value (16 bit): 0x0 {5B 07 00 00 01 00 00}

Change via >> Setup_var 0x663 0xhexvalueyouchoose / example setting -200 (Negative set below first) >> Setup_var 0x663 0xc8


Core Voltage Offset >> Offset Prefix - Sets the offset value as positive or negative.

Offset Prefix, VarStoreInfo (VarOffset/VarName): 0x665
One Of Option: +, Value (8 bit): 0x0 (default) {09 07 A1 02 30 00 00}
One Of Option: -, Value (8 bit): 0x1 {09 07 A2 02 00 00 01}

Change via >> Setup_var 0x665 0x1 / Or Setup_var 0x665 0x0

I tried
Setup_var 0x660 0x1
Setup_var 0x665 0x1
Setup_var 0x663 0x73
and saw no change in HWMONITOR

Check with CPU-z before and after those changes, also 115mv is not very much = 0.115, may be not noticed due to vdrop/vdroop. I think you made all correct changes, so should be applying

I noticed this looking now, you may also need to enable this, text help string says Menu enable but in IFR menu is right before this and then this is first setting, so maybe it's enable these settings to function and not just enable the menu (Since it's hidden anyway that makes no sense)

OverClocking Feature - Performance Menu for Processor and Memory.

One Of: OverClocking Feature, VarStoreInfo (VarOffset/VarName): 0x65D
Default: DefaultId: 0x0, Value (8 bit): 0x0 {5B 06 00 00 00 00}
One Of Option: Disabled, Value (8 bit): 0x0 (default MFG) {09 07 04 00 20 00 00} < Default = disabled
One Of Option: Enabled, Value (8 bit): 0x1 {09 07 03 00 00 00 01}

Setup_Var 0x65D 0x1

If life were that simple, we won't need this forum haha : ). No go with 0x65D

On the other hand, thanks for the address for Voltage offset. It works like a charm. more importantly, my machine BSOD much less frequently. 

Offset by -140mv.

RealGM - I only meant maybe that (0x65D) needed to be enabled before the other settings would apply. "Chipset" or Second "Advanced" (I forget where it's at and don't have BIOS open right now) would need to be visible for that setting to actually make a menu appear or disappear. Good you were able to get -140 applied, and it's great this is making less BSOD's for you! Where is voltage shown in that image I can't see it, what was voltage before and after? I thought maybe BuP4uk had something incorrect, and it seems so due to his reply above Sad

BuP4uk - reset CMOS, if that does not work, do long reset CMOS (Remove main battery, unplug from wall/power block, press and hold power on button for one+ minutes), then see if it will start or not. If not, you will have to do extended clear, all that I just mentioned plus remove CMOS battery and leave all without any power for 8-12 hours.

Are you in correct EFI-Shell/grub, all black and gray text (no yellow text anywhere)? Difference between 0.115 and 0.140 is not enough to cause the system to not function, max negative value wouldn't even do that. Sounds like you possibly entered and incorrect value and caused some error. Correct value for -140 would be 0x8c

Thanks Lost_N_BIOS, really appreciate your time and help. =)  It is in the VID column, I was averaging 0.905V when running Prime95 power consumption test when undervolting at -140mv. While that works it crashed at 3dmark, so I decreased the undervolt to -120mv, now it averages around 0.94V with prime95.

I was looking at the list and see this:

0x2ED9B One Of: Maximum Memory Frequency, VarStoreInfo (VarOffset/VarName): 0x7C6, VarStore: 0x1, QuestionId: 0x33E, Size: 2, Min: 0x0, Max 0x1025, Step: 0x0 {05 94 4E 05 4F 05 3E 03 01 00 C6 07 10 11 00 00 25 10 00 00}

Is this a continuous variable? I get memory error at times and I'm wondering if I can downclock it. 

Thanks again!

I see now, thanks! Maybe BuP4uk can figure it out on his eventually! For the Maximum Memory Frequency, see the setting right above that, I think maybe this is some fail safe or "Safe" memory speed thing, due to the one right above that. "MRC ULT Safe Config" but it's disabled by default so maybe changing the one you mentioned wouldn't apply at all, only a test would let you know. If it does nothing, enable that MRC ULT Safe Config and test again, then if nothing you know it's not what you want to downclock memory.

I think this is how you do what you want, you need to set several items to change the ram speed (Now, this may get limited by what you mentioned above, if enabled and set to some value = leave disabled, don't change and use this instead)

Memory profile >> Change to custom
Memory Reference Clock >> Choose 100 or 133, based on your desired outcome speed
QCLK Odd Ratio >> Enabled, so all multipliers can be used at either 100 or 133 above
Memory Ratio >> Set whatever your want (memory Reference Clock 100 or 133 x value set here >> 3-15 available)
Memory Voltage is also available to change, as well as many individual timings and command rate (NMode 0=Auto, 1=1T, 2=2T)
