Intel Core i9-13980HX Undervolt - Observations and Questions

That should be OK as long as the ThrottleStop folder is in the same location. Best to create a new INI if you decide to move ThrottleStop to a different folder or different drive.

Try running LatencyMon

It might show a badly behaving driver or something like that which could be causing your jitter issues.

I actually took a look with latencymon the other day. It was a Windows service that seemed to be creating issues. Just finished the reinstall and its working great so far. We'll see how long this hold up.
Since I have screenshots for throttlestop, I can just copy my settings that way instead of moving the ini. Let ya know if I hit any issues, appreciate the help you've given me!

Sorry for bumping the thread. I have a Strix G16 laptop with the same CPU. Do you need to set both the P core and P cache offset to the same value in order for the UV to take effect?

Usually. Do some Cinebench testing to confirm what works best.

I tested Cinebench 23 with -160mv on both core and cache and scored around 34k, a bit lower than the 35k I got previously with a setting of -160 core and -110 cache. Maybe it's the recent Windows and Asus bios update. I noticed that the core has a default Iccmax set to 240 and cache set to the highest 511.75. Perhaps I need to slide the core to that value as well? Will this increase my CPU temperature?

Hey! Glad this resolved it for you Jittery might be too much filesystem corruption so try repairing those before reinstalling windows, might save you time reconfiguring all over again.
For the sake of talking about undervolting... I have managed to have further more undervolting for my i7 13650HX

Currently new undervolt:

• CPU Core= -185.5mv
• Intel GPU= -40mv
• CPU P Cache= Previously was -125mv now... -250mv
• iGPU Unslice= -40mv
• System Agent= -40mv
• CPU E Cache= Previously was -137.7mv now... -147.5mv

I was shocked when I can go this deep with CPU P Cache/Ring because I tried to go higher like -270mv and I got BSOD after 5 min. but I tried to go -260mv stable but I would see jitters so... finally went with -250mv was stable and it is been over 4 months now stable on everything I throw at this CPU.

Of course obviously no OC just using stock frequencies with undervolt

What are the current undervolt settings you can recommend for the 13650HX Asus ROG Strix G614JV? dear theboss



now default settings

View attachment 401201View attachment 401202

now default settings

start at -100mv on Cores and -125mv on P-core cache, and start from there until it crashes. After that test out -60mv on e-cache and start from there (not all CPUs can handle E-cache undervolts)

Which application do you recommend for benchmarking?

I still haven't had a crash but my temperatures aren't dropping for some reason.

Your computer appears to be power limit throttling. If you reduce the voltage, the CPU will run faster. If power consumption remains the same, temperatures will also remain the same.

Which application do you recommend for benchmarking?

Cinebench R23 is a consistent CPU benchmarking test.

Cinebench is the perfect tool to compare CPU and graphics performance across various systems and platforms

Open the ThrottleStop Limit Reasons window so you can watch for any power limit or thermal throttling while Cinebench is running. Most laptop computers with HX processors will throttle. Knowing what type of throttling allows a user to make adjustments to try and solve the problem. Turning on the Log File option in ThrottleStop is also useful.

Setting V/F Point 1 to 150 or 160 can help stability.

I prefer to set IccMax to the max, 511.75, for the CPU Core, P Cache, Intel GPU and iGPU Unslice. I set Power Limit 4 to the max, 1023. These adjustments can help avoid some types of EDP current throttling.
