indeed i was surprised too, the sku seem to be used across few models, a deeper search on eBay will yield half what you initially found (still outrageous imho), SC has its own dedicated ribbon connected to a separate logic board off the mainboard, what you are looking in the image is below the battery and the plastic cradle that holds the M.2 bays, the two elements appear to be independent (main board is out in the image below, keyboard is still in place),

seems relatively easy to access, its located right under the fans, and above a small removable port module board on the right side,

@craigeryjohn i thought you will need to replace the entire keyboard, looks like the power button is not part of the main keyboard layout, should be fairly easy to swap with fingerprint power button (part number X029X) here is a closeup of the part sku (maybe you could scan the barcode to find the exact part number)

on the topic of CAMM since Dell marketing paid so many influencers recently to promote their CAMM module i did my reading and i cant help but lmao, how is it possible that so many clueless marketing personnel and executives signed off on this campaign blowing Dells money out the windows with a educational campaign why "shorter traces" is key and should be explain to the masses why they should adopt CAMM modules, what a bunch of degenerates, all they needed to explain in layman's terms is that even one physical CAMM module operate at quad channel speed over So-DIMM max dual channel speeds, So-DIMM also requires at least two modules to operate in dual channel speeds. (without even getting into other module benefits, just about everyone can understand these simple perceived benefits)

the traces leg argument this new schema argues it is so-called solving is again (in my view) a big marketing hype keeping away from asking the right question... so what happens to all other board traces if only ram traces are optimized for lower latency and other are not? unless all components operate at these speeds with same "short" traces benefits everything else will bottleneck, we already far surpassed diminishing returns point for what hardware can do in a mobile chassis atm, physics hasn't changed last I checked so where is the heat is going with 16 efficacy cores and 8 performance cores? it is inevitable that intel will shortly release 16 efficiency 16 performance for mobile chips too, i wish manufactures focused on optimizing their hardware little more like apple rather then follow a pointless eye candy hype for a premium,

before everyone panics... this is a factoring limitation when Microsoft Virtualization-Based Security (VBS) feature is enabled (this feature can be disabled manually) some applications might not work properly ( @Aaron44126 the article i read mentions some features will not work properly when this is enabled one of these is "Manual fan speed control might not work."), i think this issues been addressed for us already and why we cannot run virtualization with undervolting atm,

great minds think alike 😉 I will miss the days when Dell was synonymous with quality and Precision meant uncompromised performance.

that will render the 7X70 platform and many other with lackluster cooling solution unusable and pointless. this only effects 12th gen cpu?

you've taken the devils advocate angle more than once now, make me think you're a lawyer or a detective or something in those lines 😄 technically you cannot cause physical component damage when undervolting, even in unskilled hands, overvolt is another story but no one is overvolting an overheating laptop, the trend is to undervolt to make it useable, as for few bad apples, it is no different from one buying a new car and abusing it under warranty, nowhere is mentioned that one is not suppose to open his machine or make adjustment, if they are reading their sales metrics trying to correlate losses/returns they should look inside instead of coming up with nonsense, bottom line is... if Dell did their job in the first place none of this would be necessary.

well... if engineers at dell are out of important things to worry about why not kill their one and only saving grace? that will surely increase sales through the roof, another drunken immature executive decision, by the time Michel Dell will learn through spreadsheet and graphs his company is going down the drain it will be too late. R.I.P DELL

which cpu is installed on your system? the numbers I been posting as reference are for the 12950HX variant, i am not any form of authority when it comes to TS, i can only offer my personal experience, for more in-depth you should contact UncleWebb who is the author of TS, the way i work on undervolting is in increments, i do not undervolt for a specific formation rather to cpu's full spec and then lower core clocks etc., i start with cpu core undervolt settings first, next i set cache ratio and then move on to undervoting P Cache, after P-Cache is set i move on setting E-Cache, only after all cores been undervolted while cpu is stable in full default clocks i will look into locking performance cores at 4.7 etc. the order is as follows CPU Core Cache Ratio CPU P-Cache CPU E-Cache Lock Turbo Group to 4.7Mhz for each i go from 0 in -25mV increments, when you crash or fail revert to previous 25mV setting prior and move on to test the next value, rule of thumb you only make one change each time and test, if you mix too many variables you will never know which change made a positive or a negative effect, you than push in increments until the system crashes or fails during bench, that is your top threshold, from that point backoff +25mV and move on to test the next variable, below turbo groups you will see few ratio preset in form of button, you can manually set the clock speeds or click a preset and they will all be set to that, when i say lock all cores to 4.7 i mean just that, set them all to go max 4.7Mhz, this is preventing from cpu ramping up to 5Ghz where its generating more heat then efficient performance,

YVW (hardly a collection bit technical know how) they are critical to unleash full power, the first layer is the bios power plan, there is a reason they created 4 plans and they each have their characteristics (imho the logic behind them is very old and not very suitable for the new generation cpu), nevertheless that is the first power definition layer, that layer regardless of windows power plan will set a starting point limits on power distribution fan operation etc., on top of these limits will come windows own power plan and their logic, but they cannot change initial bios power settings but execute over these set limits, as bios windows also have separate power plan for a reason it is not "automatic gear" operations you have to manually shift "power" gears, it is not ThrottleStop it is most likely your paste job, somewhere in this giant thread i gave step by step instruction for one of the users on how to properly repaste, make sure you brief over that and go for another repaste, i have ThrottleStop running as a task always in the background with stable undervolt you should have no issues, remember you need to back off 25mV from your highest sustainable undervolt, are you confirming that locking performance cores at 4.7 gives you better performance then default unlocked?

there are few steps to get classic power to work, its not as straight forward as it should (clearly MS don't want us to use classic because they made a new fancy app like interface they want us to use and debug for them), enable S3 in bios same way you activated undervolting with command below, afterwards it will be available for powercfg, # Enable ACPI S3 Support (default 0x1) setup_var CpuSetup 0xE 0x0 next you need to disable modern sleep and turn on classic in windows, backup the following reg hive than delete it and everything below it, afterwards recreate it with nothing under it, "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\ModernSleep" import the following reg keys [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power] "PlatformAoAcOverride"=dword:00000000 "CsEnabled"=dword:00000000 reboot after the above, next put this in a batch and execute as admin (adjust your file path as needed) powercfg -import "D:\System\Scripts\POW\High performance.pow" 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c powercfg -import "D:\System\Scripts\POW\Power saver.pow" a1841308-3541-4fab-bc81-f71556f20b4a powercfg -import "D:\System\Scripts\POW\Ultimate Performance.pow" e9a42b02-d5df-448d-aa00-03f14749eb61 :: (Power saver) powercfg -duplicatescheme a1841308-3541-4fab-bc81-f71556f20b4a ::(High Performance) powercfg -duplicatescheme 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c ::(Ultimate Performance) powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61 to execute the above batch you will need the classic .pow files in path which i have posted here for everyone, inside i also included Modern Standby Disable/Enable reg files to make changes needed and the batch file i use, just edit path in the batch to point to where you keep .pow files, after you execute the batch as admin if classic doesn't list it is windows acting up, run the batch again as admin they will show!!! https://www.mediafire.com/file/k4xwiu14yeop9uy/POW.rar/file archive pass: notebooktalk.net here is my "power switch" script i rewrote from earlier version i use it to activate best power options for workloads and back to cool power saving when clicked again, it will turn on ultimate power or best performance in windows, disable NVPCF driver (this needs admin rights, the script will self elevate) and switch bios power to Ultra Performance, and vice versa when clicked on again it will revert back to cool in bios and best power efficiency or power saver depends on if S3 or Modern Standby active, and re-enable NVPCF driver, the script is designed to work with either Classic Power plan or Modern Standby schema active, reboot not required when switching, put in PowerSwitch.bat @echo off setlocal enableextensions enabledelayedexpansion :: Check admin mode, auto-elevate if required. openfiles > NUL 2>&1 || ( :: Not elevated, Elevate. echo createObject^("Shell.Application"^).shellExecute "%~dpnx0", "%*", "", "runas">"%TEMP%\%~n0.vbs" cscript /nologo "%TEMP%\%~n0.vbs" goto :eof ) del /s /q "%TEMP%\%~n0.vbs" > NUL 2>&1 ) mode con: cols=35 lines=3 & color a @echo off REG QUERY "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\ModernSleep" /v EnabledActions > nul IF %ERRORLEVEL% EQU 1 GOTO ModernSleepOff GOTO ModernSleepOn :ModernSleepOn REG QUERY "HKLM\SYSTEM\ControlSet001\Control\Power\User\PowerSchemes" /v ActiveOverlayAcPowerScheme | findstr /i "777" >nul && (REG ADD "HKLM\SYSTEM\ControlSet001\Control\Power\User\PowerSchemes" /v ActiveOverlayAcPowerScheme /t REG_SZ /d ded574b5-45a0-4f42-8737-46345c09c238 /f >nul & REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\Power\User\PowerSchemes" /v ActiveOverlayAcPowerScheme /t REG_SZ /d ded574b5-45a0-4f42-8737-46345c09c238 /f >nul & powershell -Command "& {pnputil /disable-device 'ACPI\NVDA0820\NPCF'}" >nul & powershell -Command "& {Import-Module DellBIOSProvider ; cd DellSmbios:\PreEnabled ; si .\ThermalManagement 'UltraPerformance'}" & echo -=== Best performance Active ====-) if %errorlevel% equ 1 (REG ADD "HKLM\SYSTEM\ControlSet001\Control\Power\User\PowerSchemes" /v ActiveOverlayAcPowerScheme /t REG_SZ /d 961cc777-2547-4f9d-8174-7d86181b8a7a /f >nul & REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\Power\User\PowerSchemes" /v ActiveOverlayAcPowerScheme /t REG_SZ /d 961cc777-2547-4f9d-8174-7d86181b8a7a /f >nul & powershell -Command "& {pnputil /enable-device 'ACPI\NVDA0820\NPCF'}" >nul & powershell -Command "& {Import-Module DellBIOSProvider ; cd DellSmbios:\PreEnabled ; si .\ThermalManagement 'Cool'}" & echo ** Best power efficiency Active **) GOTO END :ModernSleepOff call echo OK >nul powercfg.exe -getactivescheme | findstr /i "saver" >nul && (powercfg -s 4b87c29d-e3cd-43bf-bdf8-202cc11f6f94 & powershell -Command "& {pnputil /disable-device 'ACPI\NVDA0820\NPCF'}" & powershell -Command "& {Import-Module DellBIOSProvider ; cd DellSmbios:\PreEnabled ; si .\ThermalManagement 'UltraPerformance'}" & echo -====== Ultimate Active ======-) if %errorlevel% equ 1 (powercfg -s a104489f-31f2-47b5-b73a-d56bd7ef4926 & powershell -Command "& {pnputil /enable-device 'ACPI\NVDA0820\NPCF'}" & powershell -Command "& {Import-Module DellBIOSProvider ; cd DellSmbios:\PreEnabled ; si .\ThermalManagement 'Cool'}" & echo ******* Power saver Active *******) GOTO END :end TIMEOUT 3 > nul goto :eof Edit: to make the bios changes in the script above "Dell Command PowerShell Provider" is required!

i want to believe its just a matter of getting the right hint/tip/lead where to look for, if anyone can do it it's you, I believe you will figure it out eventually! if anything Dell has made bios operation and management fairly easy now days with PowerShell commands that can changes any settings from within windows, windows power management still communicates with the EC to ramp up fans (I think, EC could also be sampling temps (can we fake temps to fool ec?))

fan control solution is needed more than ever for the 7X70 line lets go Aaron \ o /

@dude123 there's no fan control/override solution for the 7X70 line yet, no third party including @Aaron44126 Dell Fan management works atm, to get the most out of my system during testing i activated S3 power management, disabled Modern Standby and activated classic power plans including ultimate power, if you scroll back i posted a small script to help switching between modes, during none stressful day to day operation in run on cool in bios and power saver in windows, when needed with one click I can switch between modes for high power operations, it is important to have the right combination in power plan to unlock everything the platform has to offer during bench, you don't have to switch to S3 or classic power plans you can still switch modes with Modern Standby set to best performance and in bios Ultra Performance, for best results in CB23 hybrid screen mode performs better since the task is cpu bound, for 3DMARK you want to switch Hybrid mode off and disable NVIDIA Platform Controllers and Framework driver, but first dial your cpu undervolt, with my undervolt for CB23 test i am able to lock all Performance cores to 5.0Mhz and Efficacy cores to 3.6Mhz, other benchmarks don't like this but CB23 doesn't seem to care, i also optimized my system services and background process to very basic (50 processes at idle) 17k is not great after repaste unless you were using the wrong power plan at the time (you need to be on Ultra Performance in bios and max power in windows), you should be hitting 22k-24k repeatedly for a single run (with 2min cooldown),

try setting bios power plan to "cool" and windows power plan to "best power efficiency" (my idle temps below),

I believe you can, prob using MSI Afterburner .NET class under the hood, there is also EVGA Precision X1, but development ended since they exited the GPU market, (final X1 Precision build with 4090 support v1.3.7.0)

parameters values may vary from one system to another based on the user choice, but the same parameter exist in all 7X70 bios, Dell also packs one bios update for both models because they are the same, on my cpu bin they do, test your cpu for what it will accept, for all -mV values reduce in -25mV increments to find your bin comfort zone, test each parameter on its own until you find its limit then go back +25mV, (my bin can accept up to -175mV but I'm not comfortable with that) Cache Ratio and Turbo Groups all play part in your final results, only for these two parameters use the values i posted (if you don't set Cache Ratio properly you will likely find that your system crashes as soon as you try to undervolt P Cache),

since few of you out there having issues finding CSME that matches our models Intel ME version (It's not about the latest CSME tools version it's about matching tools to our models Intel ME version), here is my personal CSME System Tools v16.0 r8 that works with 7x70 in a self extracting archive or rar format archive pass: notebooktalk.net @zexspart01 not sure why you need the tools in the first place, to edit your bios settings you don't need CSME tools, members on here have figured it all out for everyone, all you need to do is to apply the commands required to activate the features you're after booting from a usb drive with GRUB on it, the only time one needs CSME tools is to dump bios image initially in order to locate features of interest, the address its located at and the options available, once that's all figured out there is no need to dump another copy with all variable known in advance, you want to follow instructions below to apply them on your system, 1. Download grubx64.efi file from v1.0 alpha release available here 2. Get (or format) a blank FAT32 flash drive. 3. Create a folder called EFI. Within this EFI folder, create a folder called Boot. 4. Place the grubx64.efi folder above into the EFI/Boot folder path. 5. Rename grubx64.efi to bootx64.efi. You should now have a flash drive with one file, bootx64.efi, located in the path X:/EFI/Boot (where X is your flash drive’s drive letter.) Time to boot it! 6. Disable Secure Boot in BIOS and Boot Prepared EFI USB Drive Before your computer can boot the EFI flash drive, you will have to disable the Secure Boot option in your BIOS. Then you can access the Boot Menu and select your flash drive to boot into a modified GRUB terminal. You should now have the ability to execute the command “setup_var” to read and edit settings of interest, which are stored as EFI variables. here are the bios commands i applied on my system setup_var CpuSetup 0x132 0xAA # set IA AC LoadLine LSB to 170 (1.7mOhms) (default 0x90) setup_var CpuSetup 0x133 0x0 # set IA AC LoadLine MSB to 0 (default 0x01) setup_var CpuSetup 0x43 0x0 # CFG Unlock (default 0x1) setup_var CpuSetup 0x10E 0x0 # Overclocking Unlock (default 0x1) setup_var CpuSetup 0xE 0x0 # Enable ACPI S3 Support (default 0x1) setup_var CpuSetup 0x42B 0x1 # Enable PCIE Resizable BAR Support (default 0x0) here are my ThrottleStop Undervolt settings for my current 7770 bin (below is for reference, do not copy these test your own bin limits than back off from your top limits, for further reference anything above -125 to -150 is considered aggressive undervolt, you don't want to go above that.) FIVR: CPU Core -122.1mV (effective -125mV) with IccMax 185.00 CPU P Cache -122.1mV (effective -125mV) with IccMax 185.00 CPU E Cache -97.7mV (effective -100mV) Cache Ratio > Min/Max value 8/36 Turbo Groups > all performance cores set to 47 MSI Afterburner Settings Power Limit (%) +130 Core Clock (MHz) +200 Memory Clock(MHz) +1300

i would try to redo the usb stick, format it first then populate with a fresh downloaded clean image and MediaCreationTool again, if that still doesn't work ill have another route for you but it will be bit more technical,

Ripjaws DDR5 SoDimm 64GB kit I picked off Amazon worked out of the box with no issues, as you can see from CPU-Z above it is running XMP3 with declared clocks, had to wait 2-3 min on first boot while system was testing new kit clocks, that followed by a system confirmation that ram changed and that was it,

time to make it official...

you will first need to activate raid in bios, then you should have a secondary raid management screen you can hit hot key combination to enter the console the same time you can hit F2 or F12 for boot option or entering the bios, i don't recall the key combo to enter the raid menu on the dell 7770 (i think its Ctrl+R during startup) it should be listed in bios when you activate raid how to enter raid management console, from there you should be able to enable disable RST,

another really annoying issue i chased as well is the clock, volume, WiFi, and power controls on the right side disappear, they will come back as soon as i call up task manager they become visible, if i minimized all is still good until i close task manager completely they will disappear again, the solution to fix this once and for all is to paste and run the following in a batch, @echo off REG ADD HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced /v TaskbarSd /t REG_DWORD /d 1 /f taskkill /F /IM explorer.exe & start explorer
