there's a lot of hives nested in this bios, searched through what made sense (temperature, speed, thermal, fan, rpm, pwm, acpi) found many hives with interesting sections including keywords above, i was unable to decrypt some hives, the few i was able to decrypt i didn't get the chance to go through yet, have at it 😉 File_DXE_driver_05B17EF3-26CB-444A-82F7-92705CFB6B1E_DellSetupFormSets IFR.rar

there's few more sections in the raw bios dump i didn't decrypt yet, later this evening ill try to extract and decrypt the other sections maybe we can find a lead there,

got it! line 25325 & 26443 mentions "CPU Fan Speed"

look at line 25186 "Platform Thermal Configuration" and below the keyword for thermal configuration are the "trip points" seen below "Platform Thermal Configuration" section, isn't that the fan curve?

@win32asmguy i can see the temp curve settings in the bios options (trip point 0 and trip point 1 etc., there's even more specific fan speed variables) they are just hidden from the end user, likely can be overwritten manually to change Dell's default behavior, one just need to further decipher the current embedded logic off the bios dump i posted,

its not direct or a huge influence but it is still some influence a user can utilize to some extent, for example i like to keep my CPU Mhz as low as possible when idle, its just a weird cork of mine, i don't like it when the system ramps up to crazy high Mhz's for no reason, if its not doing anything i want it at the lowest 799Mhz per core, i use the power policy to influence this behavior bit, if i run active cooling policy the system will allow the cpu to ramp up in Mhz when idle counting on the fans to keep things at bay, while if i chose passive cooling the logic is to keep CPU Mhz low first before fans are used to cool things down, this result in slightly (relative!) higher temps as fans are not always running while the CPU is kept relatively cool by its low Mhz merits as a base logic,

@Kataphract you misunderstood me, in that post i partially quoted myself from earlier post, in that post there are 7 or 8 images which i edited out in my quoted response, follow that quoted bit to its full post and you will find the other images, or simply click here

@Dell-Mano_G Thank you for the heads up, it does looks as if the SODIMM module is removed a CAMM memory module can be installed in its place, i was not swapping modules back and forth, this is how my system came, with the SODIMM pre installed, that's what i meant when i said "in hand" not my actual hand but in my system 😉 ,

i sure did, if you follow the link to the full original post there will be more pics with each step described,

same here :) i posted the full bios dump, i'm sure there some fan controls there that can be further modified, you can also change active power plan passive/active fan policy, passive will allow some heat buildup before activating fans vs. active where fans will always run to keep things cool,

14k score single run and 13.5k for 30 min run pre repaste, see below (on the right 30 min run, left single) 24.5k is a 74% improvement from Dell's original baseline (after going through many hoops to get what we paid for), in the Fiver control window there's a chart on the right corner summarizing changes, -125mV on the main core with IccMax 255.75 -75mV on P cache with IccMax 255.75 -75mV on E cache and all Cores set to 4.7Mhz no one setting makes this huge leap, its the cumulative effort of all settings together, 16 core CPU beating a 24 core Xeon and only 20% shy off the top 32 core Threadripper is respectable, considering the CPU is essentially still capped off, and resides inside a tiny chassis with lets face it not so great cooling solution, (though some may contest the cooling effectiveness due to these scores, consider the system is still throttling unless i also set PL1 at 80 and cap PL2 at 100 which puts CB R23 score at 19k)

now that's impressive Multi Core and Single Core Multi Core 30 min stress test your system miles may vary... these settings work on my Precision 7670, (with liquid metal application on the CPU side)

i had to go there... to make things simple here are the two commands needed to unlock and free Precision 7X70 for full Undervolring/Overclocking setup_var CpuSetup 0x10E 0x0 # Overclocking Unlock setup_var CpuSetup 0x43 0x0 # CFG Unlock Happy tuning everyone 😉 those interested in the full BIOS Dump Decrypt here it is DELL 7X70 BIOS Decrypted.rar

though not new to computers i am also new here, what i did is described in my posts, most of the information is in this thread, follow Aarons link in the post above me to apply the tweak, i had good results with PL1 set to 91 + locked MIMO

hmm... you think? got it! followed your link, indeed that is possible i didn't verify their operation, i wonder if blocking these internal outlets will improve airflow to the back radiator, seems to be wasting allot of static pressure going toward the one populated SSD slot, if i place my hand on the back where the radiator is there's barely air flow id expected from two fans (gotta test this now :D ), i couldn't agree more, this is a poor neutered design to a very capable cpu from a very capable company, there may be a way to remove the "cpu lock" through the bios than undervolt it, not sure ill venture the route, the lock is likely artificially imposed through the bios designed to prevent overclocking not undervolting 😉

the XPS 17 has a vapor chamber thermal design, it is different than the 7x70 series heat pipe thermal design, i had some hand on time not long ago with the XPS 9710, excellent piece of equipment, i got the 9710 to run full blast with zero thermal throttling no matter what i dished at it,

did even more testing, despite scoring pretty constantly now 22+k in CB R23 the unit ultimately still thermal throttling getting there, i noticed in a mixed stress test that the unit does manage to handle its relative power reduced -60% before it settles in, even in that mixed test when temp reached equal Librium GPU was around 81 with 91 hotspot, CPU was at 76, when i say mixed stress test that's all options in AIDA64 selected and the system allowed to run for an hour, even went the route of liquid metal on the GPU which didn't improve anything reverted back to paste before shipping the unit back a more robust vapor chamber design could easily run HX without thermal throttling, i am sure the blade 17 with its vapor chamber cold handle the HX with more grace, these two sad heat pipes cant carry the load short of capping the CPU itself, this powerful CPU can only run in this chassis at 40% capacity atm, also noticed the fans this unit equipped with don't really move much air , even when at full rpm there is relatively poor air exhaust in the back,

cant upload more images to my previous post, here are the changes made in ThrottleStop TPL settings to achieve last test result,

those who wanted to see the SODIMM module here it is

here are some test result pics from my runs single run next to 30min continues run results prior to repasting, single runs (post repasting) after editing @win32asmguyIA AC/DC LoadLine next... cooking with fire :) (i may have to eat my words and keep this baby after all), (disclaimer... results may be further hindered by my system running in single channel memory mode atm)

the past 48h I've been hands on putting the 7670 to the test, it became apparent through Aarons thread here that there's some thermal issues to deal with, with my past experience this should be a walk in the park for me, or at least I thought it should, before I dive in deeper a Thank you Aaron, I came across you fan tool and tried to run it here, unfortunately it bugged out on my system for whatever reason, I didn't dwell on it too much as I already formed my opinion, I am an avid fan of Dell and in particular their mobile Precision line, i have been since my first M60, stopped counting awhile back, this unit should be my 10th Precision mobile workstation by now, started seeing diminishing quality and engineering efforts the past 7-8 years, this pattern sadly gotten deeper instead of changing on its tracks, the 7670 as much as i wanted to love it will unfortunately be going back to Dell, this is just poor thermal design no matter what efforts one will take there is just no way to tame this beast, the old heat pipe design just can’t keep up, there's only two heat pipes one for the GPU and one for the CPU being shared between both, when this thing fires up it’s just too small to handle the heat, it needs a vapor chamber design to stand a chance with these powerful CPU's, short of that this unit is unable to run at its full potential as its immediately capped off to crawling speeds to cope with heat that's dissipating over a short not meaty heat pipes, as a comparison i recently tuned a Dell XPS 9710 with i9 11980HK which i was very happy with, end results are very similar to what we are now getting with the 12950HX (see results here) i ended up stripping all Dell pads and thermal application replacing it with proper grade paste and pads, i also did a liquid metal application and pushed the system until I was able to (artificially) iron out 99% of thermal throttling, even than the system is unable to push through, the best i was able to push (with allot of efforts) the system is to 20k on CB R23, these are synthetic result artificially imposed to see if the system can still perform to its full potential removing heat any variable and still the system refuses to go any higher than 20k score, without means of further tuning the CPU aka undervolt etc. this unit is sadly keeping 50% of its capability off the table without the option to regain these resources back as these family CPU are further locked which makes no sense to me being high end workstation, while none high grade laptops are allowed to be tuned further, here are some repaste pics

i already have repasted, i did take few pics along the way, what are you looking to focus on? the existing paste was hard as a rock i had to "scrape" it off instead of just wiping, i will post my tests, findings, and conclusions in the evening later today,

i am too encountering thermal throttling issues and (relative) low performance with my new 7670, first test Dell default, after full system update and no tinkering or tweaking single CB R23 run got a score of 14089, 30 min sustained run scored 13674, tweaked the system bit and run again single CB R23 run scored 17019, 30 min sustained run scored 15268, all along system is thermal throttling through the roof, even at idle temps are at low 80's, i will see how far undervolting and repasting gets this system alog, as it is this is simply unacceptable,

make no sense to me either, every other RTX variation works and supported, what makes the 3080 an exception puzzles me, going off your hands on experience apparently there's something going on the background we are not privy to, googling exposes allot of issues with 3080/3090 and Ubuntu (im sure you sifted through these by now?),

for what its worth i looked up your specs, when i placed my order the internal Dell system configurator would not allow the agent to mix Ubuntu with the 3080, despite me insisting on Ubuntu for my OS it was simply not possible and i was forced to buy a Windows license if i wanted the 3080 in the mix (all other GPU options don't have the same issue), i did not get an explanation as to why the two are incompatible just a confirmation that they are not compatible from a higher tech before i placed my order,
