thats odd! did you change other values beside cache ratio? i suggest scroll back find my posts with under clock i applied to my system and use that as your baseline, i run all my tests posted here with the same under clock setting i did not need to further change them, they run very stable and never crashed here for me at any point,

re-flash/restore your bios

i believe you want to leave it off,

did you switch off secure boot option in bios? run setup_var and apply default values setup_var CpuSetup 0x10E 0x1 # Overclocking lock setup_var CpuSetup 0x43 0x1 # CFG lock

you can scroll back and compare with my images, i did not modify cache ratio i cant recall if the option is enabled or not,

yes, reapply both entries mentioned above,

try reapplying Overclocking Unlock and CFG Unlock in bios,

no I don't, I applied LM TIM (if scroll back you can see my posts and pics), my unit is going back to Dell soon, in prep i removed my LM TIM and re-applied Kryonaut TIM, from your pics you appear to have the same part number my unit has, my unit came from factory with the sunon fans installed,

yes!

hmm... as it turns out we can achieve the same CB23 LM TIM results without LM TIM application, regular off the shelf Kryonaut same as previous run just allowed the system to cool down,

LM TIM application in my 7670 unit bumps about 1000 point in CB23 score, below is with TG paste for TIM application with my undervolt setting published throughout this thread,

this just irks me to no end, look at cpu temps at idle, id say fair for doing nothing with LM TIM removed (Ultimate performance profile), now look at GPU temps also doing nothing, the CPU is working at extremely low loads, the GPU is not doing anything not even a basic calculation yet still temps are too high, since GPU has no activity its dedicated fan is sleeping, while CPU/GPU heat pipes intersection is overheating, thermal management seems agnostic to the situation,

if you put the numbers in place "some" becomes 50%, in most stress test i conducted i focused on CPU only, during these tests GPU hot spot was 10 degrees hotter than CPU stress temps while doing nothing,

there is a serious caveat both CPU and GPU on the same "street/side" of the heat pipe, when the CPU is working hard it automatically boosts heat level for GPU even if GPU not doing anything, the minute GPU start working it is already in disposition due to heat buildup from CPU and vice versa, the two of them on the same pipe side further exacerbate thermal conditions,

maybe something is off with the unit, are you under 30 days from purchase?

yes indeed, had no issues with S3 enabled thus far,

CB23 result with "Cool" power profile in bios are the same as with "Ultra Performance" -throttling, in windows i am running "Power Saver", for these tests i switched to "Ultimate Performance", if i stay on "Power Saver" profile for CB23 run i get 20200 with zero thermal throttling, (with LM TIM application and undervolt settings posted here + IA AC/DC LoadLine) idle temps with "Cool" bios profile + win "Power Saver" profile are around 32-36c, when its sleeping it will idle down to below 20c with all surfaces cold to the touch, (ACPI S3 Support enabled (setup_var CpuSetup 0xE 0x0) and classic Standby),

i'm slow cut me some slack 😄 i can see these hives in the bios dump, I can find them with specific keywords, I am able to extract the hive but info appears to be encrypted with newer RSA keys or some sort of tamper protection preventing from IRFExtractor accessing the data behind them, been experimenting with the 4 power plans in bios, it appears that setting to "Cool" power plan will keep the system from thermal throttling and surfaces from getting hot, all other power plans (Optimized, Quiet, and Performance)will allow power limits into thermal throttling range (PL2 110v and up, or in the event of "Quit" the system remains hot intentionally to keep fans low),

@Aaron44126 been tinkering around the bios settings, it became apparent to me that there has to be several trip points for each power plan in the bios which we have 4 of them, we are likely looking in the wrong place, some good news... I think I managed to get the system to stop throttling, currently testing stability under stress and various conditions,

@Light & @Aaron44126 would be nice if you guys could share a visual for reference where these "soft" area are, for reference i use guitar pick to pray the front gap open, slide a wide area in and gently twist like door key, lift the front up push towards the back gently, and the back should lift off its pins easily, close in reverse order, fit the back first,

call dell customer service and tell them you are having issues with the unit, they will replace it for you if you're in your first 30 days,

i am baffled by execs and engineers at Dell who whole heartedly believe this is a good design going forward, and its only for the mislay price of a small car, 7x70 are completely redesigned from the ground up and should be future proof, while we are burning hot under Elder lake architecture what will happen with Raptor lake with 16 E cores and 8 P cores in this poorly redesigned chassis, the sad truth is Dell is not what it used to be, i find myself the past 10 years giving them another chance over and over again (its mainly hope) with lame excuses all because of their "old" reputation and standards they no longer uphold, if i had to pick a laptop for light load now days i would go with XPS17 which in reality is a sleek design in a 15.6 footprint sized laptop, for heavy workloads I would sadly opt for the Razer Blade 17, the Razer Blade 17 has similar capabilities and expandability, i had some hands on time with both the Razer 15 and 17 i like the 15 size wise, but the 17 has a vapor chamber design and runs way cooler, i wonder if it has to do with some internal layout difference altering acoustics with the 7670 and the 7770, on the 7670 they are whisper quiet to the point it annoys me, most of the time i cant tell if they are spinning, for whatever reason dell went out of their way to not show fan data of any type anywhere, here you go normal run + 10min throttle test,

no, i hear nothing i have to turn the laptop over to confirm they are spinning through slits at the bottom, i'd guess its a placeholder to not veer from full gpu form factor and maintain unified rigidity, what i find interesting is the cpu has the entire thermal solution to itself and its still struggling, @keks2k i felt the same way first day or two until i got the undervolting going, will you copy my exact undervlting setting and share your CB results? without TM i would bet you will get to 22-23k easy, (note that i also locked all my cores @4.7)

mine arrived from factory with the sunon fans you will improve, sometimes less is more when undervolting, keep at it you'll get there, below is my 7670 score which I received Friday, mine also had bad thermals out of the box, i had to forcefully scrape off a dry as a bone paste on the CPU side which i replaced with LM, scroll back a page my undervolt settings are posted here if you want to give them a go,

@Aaron44126 i think we need to disable "Intel(R) Dynamic Tuning Technology" for these fan trips to work,
