Intel 13980HX Settings Review

[JelMastaFlex]

Hello!

I've been diving into this world of laptop undervolting and been having a blast with it - minus the dread of creating an expensive paper weight. Laptop is an Asus G18 I9-13980HX w/ 4080 gpu and 32gb of 5600 ram. I have gone in and removed the liquid metal and re-pasted with regular paste and did a clean install like a year ago with no armory crate and installed Ghelper.

I initially just wanted to try and alleviate some frame stuttering in games that was driving me nuts but now I'm hooked on the min/max aspect of all of this. I think I've gotten on the right track with the help of lots of research but I'm still struggling to understand some of the diag and theory when it comes to all of this and was curious if I have made myself a stable(?) future problem or a laptop that should run for hopefully a few years like this.

I followed Valour549's post and had a decent undervolt going but decided I needed to crank knobs and ruined it. So, I did alot more tuning and goofing around and here I am. I believe I'm stable but I have been a bit afraid to run R23 as I just constantly bang off of BD PROSHOT in any long format testing, but I consistently get 34k+ singles. I have ran a ton of 3DMark benchmarks with Time Spy and Steel Nomad (I was tweaking the GPU in Ghelper) and have alleviated crashes there. In games like MH: Wilds the CPU barely ever touches 90c now and my stuttering is all gone with a solid FPS increase so I'm thrilled. I am a bit worried about the temp limiter in R23 though. Not sure if I need to take a better look at that.

If VBS is enabled the first time you run ThrottleStop, it can corrupt the ThrottleStop.INI configuration file. The result will be a bunch of odd looking FIVR voltage values like 0.0391.

When this happens, the best thing to do is to exit ThrottleStop and delete the ThrottleStop.INI configuration file. Shut down your computer so it can reset the voltage control register.

I have not tried undervolting the E Cache or the System Agent. If you can prove that undervolting either of these reduces power consumption then great, leave them undervolted. If you cannot prove that undervolting something improves performance or improves temperatures then I would set the offset for those back to 0.0000. There is no point in reducing the voltage of something and risking reduced stability if it is not doing anything to help out.

I just constantly bang off of BD PROCHOT in any long format testing

I have heard of this problem in other similar Asus laptops. I am not sure what triggers this. BD PROCHOT allows other sensors external to the CPU to send throttling signals to the CPU.

I got lucky. The MSI laptop I bought has an advanced BIOS so I can disable BD PROCHOT in the BIOS. This type of throttling is rarely necessary.

Thanks for the reply unclewebb. I did as you instructed and cleared the .ini and shutdown. Booted back up and loaded in all the same values I had except the intel iGPU stuff and System Agent.

I ran a couple R23 singles and I appear to be running less wattage than before and throttling down harder so it looks like I need to readjust now that Throttlestop is operating correctly. I didn't even notice the values were off and completely forgot I had messed with System Agent. For some reason after doing the reconfig my PL1 has went up from 165 to 175. Not sure what that was about. It could've gotten stuck when I was playing with TS with VBS still enabled not realizing it needed to be off.

In regards to E Cache - with my previous config I did seem to notice a bit of a performance uptick, however I'm not sure it was something to seriously look at. I was following the Valour guide and they had mentioned starting out at -30mv and working up along with the P core and cache. Unless I read that wrong. That was the only reason I had that there, however I had been meaning to do homework on the E Cache as I wasn't sure about it either.

Should I be doing more homework on adjusting the max cache ratio on this CPU? I've seen you mention that in a few threads and I had a tough time finding material to help me better understand what I'm doing there.

Disregard the bit about my performance not being the same as before deleting the .ini. I forgot to save immediately.
