G752VS :: Lowered CPU voltage in BIOS = no more throttling

[Dreamonic]

So I recently decided to get the G752VS-XB78K. After taking it out of the box and finishing Windows Setup, I started benching and monitoring voltages, temps, etc.

To anyone that says 'clean' installs are stupid... obviously aren't enthusiasts and that's fine. I've always made a backup of the original drive that came with the pre-configured setup of Windows from ASUS onto another one or at least copied the eSupport folder out before formatting. Regardless, it is not required but it works just fine. Tired of seeing threads regarding this. Also, the NVMe drive requires the IRST driver loaded when you do a clean install of Windows during the setup in order to see it.

Anyway, back to the testing.

To my amazement, it was indeed reaching nearly 95°C almost instantly and throttling Turbo Boost clocks. The CPU 'static override' voltage was over 1.3v which adaptive makes 1.4v! So.... out comes the fun tools like AFUWIN to dump the BIOS, and AMIBCP to edit the access privileges for the additional menus and sure enough, there is an Overclocking one that's functional. You'll also have to go into the CPU configuration menu and adjust the override there for your cores as well. I'll post some screenshots. Sure enough after making the required changes in those screenshots, the temps drops to 77°C on extreme load and sometimes climbs to 80°C after a while when still at 4Ghz. This Aptio 5 BIOS is going to be so much fun to use compared to the Aptio 4 BIOS in the G751JY I had.

Now, what I would recommend doing is use ThrottleStop to find out how low you can go FIRST, before applying some random lower voltage and not be able to boot after saving it. When running ThrottleStop for the first time, you must default the voltages in its current state there to see any changes YOU make afterwards.

It's also normal for the system to power down after you adjust voltages in the BIOS and then turn back on.

This fix, literally addresses the entire issue regarding CPU throttling from higher temperatures due to the excessive amount of voltage applied under the "Extreme" profile.

I'm currently still testing things out with the machine so later on throughout the week, I'll post more up.

EDIT: Definitely uninstall the ROG Gaming Center and never use it! It affects and adjusts the settings I manually changed in the BIOS for the CPU OC.

Great Job! Congrats 😄

Not bad for a newb. Has nothing to do with clean install but more with BIOs and VBIOs tuning. You always were good at that. If I didnt just blow a wad of $$ on a desktop build Id go OS for OS with you, not much for hacking the BIOS. I do OK with one that's already open. I wasnt going to buy another laptop and got tired of waiting on ASUS to release the X2 GPU dock so I invested in a Z170, 6700K and two Strix 1080s in SLI. I cant hit 16K FS on one card if I turn everything down to nil. Mild OC on two in SLI is getting me 26K. Havent had time to push it just yet. Waiting on the 960 pros to put in a raid 0 array before I go ahead and push it hard. For a non enthusiast I managed to get the 6700K to 4.8 Ghz stable on 1.375V I know it has 5Ghz in it.

So I did -100mv, set all core to 3.8ghz, ran some fire strike, unigine, Ts benches, cinebenchr15. All looks good but then, 8minute into witcher 3 at ultra, it crashed and caused a reboot. 10 minute into Tomb Raider and it crashed. What the hell is going on.....is it the multiplier, or the undervoltage, or is it the overheating(can't get a reading because it crashed n rebooted)? I followed Miguel's starter set up :(. Any suggestions?

[Dreamonic]

It's your undervolt.

When you set the core multiplier higher (38x, 40x, etc), Vcore increases as with Adaptive voltage based on the set multiplier. This in turn affects how low you can undervolt while keeping stability in check.

Stock multiplier will be stable with an undervolt usually around -100mV to -150mV. Then, as the multipliers are increased (overclocking), that range could be around -12mV to -50mV (bin dependent of course). If your CPU die was from a good yield, then chances are your undervolting range will be really good as well.

It's definitely something you need to test (like in games or benchmark runs) to know what is stable and what isn't, before running it as a daily profile. When crashing occurs, adjust your undervolt and proceed to test again until no crashing or system halts, shutdowns or restarts occur again (complete stability).

Thank you! I thought 38x was default for -100mv to -150mv. I bumped down to -90mv and did some benchs + games. NO crashing! Did 3 hours of witcher 3 ultra 60fps with cpu temp of 80c and gpu 73c. Also 3hours+ Tomb Raider at very high with cpu 80-82, gpu 73c. And amazingly Fire Strike score of 14k+. Great thanks to Miguel as well :)!
To the guy wondering about Backlighting: strangely led still works, as well as backlit keyboard without gaming enter. No clue what's going on there...... Sonic Studio works as well.*

"...backlit keyboard without gaming enter. No clue what's going on there"


Putting this out there...

Keyboard backlight has nothing to do with Gaming Center.

Also, the link from this post above no longer works.

Hello, I got a g752vm, but I'm really noob at tweaking pc's, how can I do this safely and efficiently? All I want from my pc is to lower heat with same or similar performance, thank you!
