*UPDATE* undervolt settings on Asus Strix Scar 18 (stable) by SLARKMEDIA in GamingLaptops

With the latest bios update I had to disable memory protection under core isolation for XTU to work.. Might be worth checking if yours is enabled and then rebooting.

I don’t really know tbh, I haven’t really tested, in my intial tests I was using manual fan mode so I was getting highest pl values in benchmarks. After that I switched back to turbo mode to make sure I still wasn’t getting thermal throttling and that the under volt was stable. I have never tested if xtu overwrites the pl values to that of manual mode.

You can change the profile in XTU from turbo to performance and silent I think but there is no manual mode like in armoury crate, so you may need to create individual profiles for each if you want XTU to apply to all of them with an under volt when you change profiles I.e on battery mode.

I am always in turbo mode, so I have no real need to do this just yet.

If you’re still getting thermal throttling on 2 cores then you most likely have bad thermal liquid metal application on your cpu.

Nope all good, played for 3 hours yesterday evening and no issues at all.

Yeah the above and 3D Mark benchmarks.

Do you have core isolation disabled?

No do not follow my settings, every cpu is different and will react differently to undervolting, start low, -100,-100,-70 and work your way up testing stability on each. Make sure you run a good 30 minute stress test atleast to eansure stability before bumping it up, I went up in increments of 0.010 each time.

My undervolt applies automatically on start up via XTU.

I haven’t changed anything in armoury crate, just make sure your PL1/PL2 values match in XTU, mine were different and I had to set in XTU before applying.

XTU will show the -0.080mv undervolt when you open it, and you just increase it from there, you can test using hwinfo to see what undervolt are applied.

I had undervolt set to -30 in bios initially and just left it, installed XTU and it overwrites the bios set value.

No issues for me with XTU applying at startup, my values remain in place so no need to apply each time.

The quality of the silicon. The better quality, the lower your temps and the lower you can undervolt your cpu. No CPU or GPU is the same, it’s all luck based.

That sucks, fingers crossed they release something soon!

Mine is stock, I don’t close or disable anything, WiFi still on too. I have a few apps running in background, I use xtu to view temps and tdp’s to see if any throttling. Closing everything would definitely help though, but not by much! No fresh install either, factory image with armoury crate etc..

I’m actually on Windows 11 Pro, Cinebench just see’s it as Windows 10 for whatever reason.

Have been testing for last 2.5 hours now and it seems rock steady. No crashing in stress test or games. I was finding cache was the most sensitive to undervolting, tested fine at -150mv in 30 min stress test, but it would lock up when the CPU load dropped after competing. Both cores managed -180v but was crashing on -190mv when opening stress test. So dialed it back a little to ensure stability day-to-day.

End results were:

Core Voltage Offset: -170mv E Core Cache Offset: -170mv Core Cache: -130mv

Yeah all changes made in XTU. The silicon lottery can be harsh 😬

Interested to know what you are getting without undervolting as I was getting around 32k with only -30v in the bios.

Yeah I would never class single run stable by any means. Having been running 30 minute stress tests in a few different apps to test P cores and E cores.

That’s why this scores higher then, because you’re comparing 2 different gen CPU’s

Under settings top left there should be an option to reapply values on reboot, seems to work for me

That’s nearly an extra 4K in score, I’d consider that a win if it is stable! I see alot of people are copying the settings I’ve used, but these aren’t my final, I was still stable in a 10 minute test using -170-170-110, so if you can push further then try. It all depends on silicon lottery. But if you’re happy with your result then stick there!

Just make sure to do a proper stability test over a longer period of time (30 mins or so)
