First time poster, and I apologize in advance if some of my questions have been answered in previous posts. I have 2 kids under 4 and its the 4th of July (Happy 4th everyone!) so I don't have time to search all the forums.
I have a 2-3 year old Dell G7 15 7590. It has an i7-9750h and rtx 2060 in it. I just upgraded the Ram to 32gb. I have a replacement heatsink and some new thermal paste on its way as well. This was a pile of garbage since the day I got it. I have finally gotten around to wiping windows, restoring power plans with Revolutions, updating drivers, setting up throttlestop, etc. and there are a few things I had some questions about since I last used this machine daily.
I was on Bios 1.9.0, which was the last Bios where undervolting was allowed on this machine. Strangely enough after a random restart all of the FIVR and TPL windows were greyed out. I followed the old method of restoring the Bios to factory settings, rebooting, going back into bios, turning off UEFI updates, wiping back to factory, rebooting, and then undervolting was available again in throttlestop. I must have forgot to untick UEFI updates after the final reboot, because the next time I restarted the bios updated automatically during reboot to 1.14.0. After this, I made sure to go into bios settings, wipe to default, restart, wipe to default, disable uefi updates, set any personal bios settings I wanted to change, and then rebooted and I still had undervolting capabilities.
I currently have the CPU core at -200.6mv, and the cache at -125.00 and things seem stable. I have PL1 an PL2 at 130 (more on this later) both clamped, MMIO locked, PL4 set to zero, Speed Shift turned on.
My settings seem good, and I can run a TS Bench and Cinebench R23 without tripping any limits. However, PKG Power maxes out at about 67 watts. Is there a way to get this any higher, or is it a limitation of my 60wh battery, or 180 watt power adapter?
Question regarding C states. It seems totally random, but sometimes when looking at the Core C States screen C7% has 0s for all cores, and sometimes it shows it constantly fluctuating like its actually trying to save power. Whenever I tick C States - AC with On radio, and click apply it never keeps it ticked. It does show some values under sleep residency for C9 and C10. I don't think my C states are working properly and not sure where to start troubleshooting. I had wiped the .ini file and updated to throttlestop 9.5 as of yesterday, prior to diving headfirst into this again.
The 3rd thing I'm curious about is whether or not it is possible to downgrade the Dell Bios beyond a certain version? 1.19 is the latest version out and I'm pleased that undervolting is still possible on 1.14, and following the same "Factory Default settings" method I would be happy to try 1.19, but I feel like I saw a thread mentioning once you go passed a certain firmware you can't actually downgrade.
Currently during all testing none of my cores are pushing above 92C and this is in a warm room in the middle of summer.
To summarize, I have 3 main questions:
Why is my PKG Power maxing out at 67 watts during stress tests? I've read some of these chips in some machines can run up to 80/90+ watts. Would this be the Dell EC Controller trying to keep it down around 65w?
Why do I sometimes see 0s in the Core C States window, when other times C7% is full of numbers? I double check Task Manager that there is nothing using the CPU in the background.
Is it possible to downgrade from 1.19 Dell Bios on the Dell G Series Laptops in the event upgrading removes the possibility to undervolt?
