need some help guys! i have opened a thread on TechPowerUp where UncleWebb has chimed in (Unclewebb is the author of ThrottleStop), i have explained some issues i was experiencing undervolting the 12950hx, in particular the issue of crashing when just enabling P-Cache undervolt feature without even undervolting, just enabling the feature will crash the 12950hx, unfortunelty i do not have my replacement system in hand yet, he will need some feedback from us with newer CPU's to help improve ThrottleStop for 12'th and 13'th gen CPU's, please chime in here to help speed ThrottleStop support for our CPU's https://www.techpowerup.com/forums/threads/throttlestop-p-e-core-support.300650/

no!

this is just painful to see, buy the 7770 from dell online outlet store for $2,409.00, or buy the exact same config for 220% more (or 55% less) from dell online store for $5,336.04,

100% true, hmm... where did i pull 26k number from i missed that bit completely in his video, i just read off the image he posted there, in a way gaming always had an edge or bit gap over workstations usually representing bleeding edge technology not fully suited to deploy on workstations (yet), but it was never this significant where a gaming station puts to shame a flagship workstation from one of the top manufacturers, come to show how much marketing taking precedence over engineering priorities now days, which is exactly what has changed the past 10-15 years with Dell,

its not like we are asking for something in the sky, their alienware line all run with a 330 bricks with proper thermals, its just handful of greedy pissant marketing executives thinking they outsmart us all, to them we are clearly too stupid to notice or know the difference, this is no longer Dells flagship its Dell's compromise ship.

that system has a heat pipe design not a vapor chamber hence the differences, they don't need to, with a solid vapor chamber the unit is able to maintain higher clocks its that simple, if you research you will see some show 60c constant temps during their tests which suggest heavy regulated cold environment, I've seen enterprise data center drivers in use in conjunction with these high scores, our platform is so far off there's no point in comparing, i also got 26k score on CB23 but it wasn't easy and it was for a single run, on a 30min loop i got 19k and again it wasn't simple to get there, the system had to be heavily manipulated first, that Asus shown tested unmodified and healed 26k score after 30 min loop, that's HUGE 40% performance losses for workstation class, when did it became ok that a workstation plays second fiddle to gaming station?

spot on! a gaming laptop that can boost a 30min loop on CB23 with a 26k score while our premium workstations can barely scratch half that score, that is aggravating and insulting that Dell has the goal to think they can get away with 50% castration on their expensive premium flagship workstation because we (used to) blindly trust them to always be the best, for general information all top 100 results on 3DMARK for the 12950HX & 3080 Ti combo we compete against are from less than a handful of users all running the same ASUS Scar 17 SE with the above basic specs, this unit comes from factory with a vapor chamber backed up by two fans, we cannot pull result beyond top 100 on 3DMARK i suspect the same handful of users logged up thousands of results as they appear to be competing with each other posting improved result, throwing off average scores for our machine class, what it does prove though beyond a shadow of a doubt (despite both CPU and GPU on that unit come with LM TIM from factory) is that proper taming of the beast is possible for this hardware level it just takes a proper vapor chamber like the one shown in the video below,

if you're familiar with Optimus or "mux switch", its a similar function just in a manual form,

there's is no higher mobile sku than the 12950hx atm

fyi ssd's are happier at 54c idle and up, they tend to be nonresponsive when cold, they require heat buildup for proper operation,

i gave it a try at the time i was not able to find all desired variables, i wasn't fully set on my underclock setting so i didn't insist on making these work from the bios directly at the time, i believe these can be set in bios just need to locate and verify their variables, (i couldn't find ring down "Voltage Mode" to set it to minus before setting a value on ring down which is variable for P-Cache) setup_var CpuSetup 0x1E8 # Ring Down Bin (Default 0x0) setup_var CpuSetup 0x263 # GT Voltage Mode (Default 0x0) setup_var CpuSetup 0x266 # Offset Prefix (Default 0x0) setup_var CpuSetup 0x26C # GT Voltage Mode (Default 0x0) setup_var CpuSetup 0x26F # Offset Prefix (Default 0x0) setup_var CpuSetup 0x2DE # Uncore Voltage Mode (Default 0x0) setup_var CpuSetup 0x261 # Offset Prefix (Default 0x0) @Aaron44126 here you go i think i fond the missing link setup_var CpuSetup 0x1E9 # Ring Voltage Mode (Default 0x0) here are few more variables that can be set setup_var CpuSetup 0x2E3 # Thermal Velocity Boost (Default 0x0) setup_var CpuSetup 0x2E4 # TVB Voltage Optimizations (Default 0x0) setup_var CpuSetup 0x378 # Enhanced Thermal Velocity Boost (Default 0x0) setup_var CpuSetup 0x7 # Expected CPU Freq (Default 0x0) setup_var CpuSetup 0x2AF # E-core L2 Voltage Mode (Default 0x0) setup_var CpuSetup 0x2B4 # Offset Prefix (Default 0x0) setup_var CpuSetup 0x27C # VF Offset Mode (Default 0x0) setup_var CpuSetup 0x1EE # Offset Prefix (Default 0x0) here is a binary converter,

@FlashWolf i cant post screenshots for you i returned my 7670 unit few days ago, going off memory so follow these steps to the T, start by deleting your ThrottleStop.ini than open TS, in TS Main window 1. in Settings section, Uncheck SpeedStep 2. in Settings section, Check "SpeedShift - EPP" 3. in Settings section, Change "SpeedShift - EPP" value from 128 to 34 (you can edit exiting value) 4. Click "Save" (bottom left window corner) click TPL tab 1. in Power Limit section, Uncheck "Disable Controls" 2. in Power Limit section, Uncheck "Clamp" from Long Power PL1 3. in Power Limit section, Change value for "Long Power PL1" from 85 to 77 4. in Turbo Power Limit section, Check "Lock" checkbox 5. in Miscellaneous section, Check "Speed Shift" 5. in Miscellaneous section, Change "Speed Shift" Max value to 68 6. Click Apply than OK on the bottom right of TPL window Click FIVR tab 1. in Save Voltage Section, Select "OK - Save voltage settings after ThrottleStop exits" 2. in "All Core" Section, click on 47 setting all cores in "Turbo Groups" to 4.7Ghz 3. in "FIVR Control" Section, select "CPU Core", than check in "CPU Core" Section below "Unlock Adjustable Voltage" and drag "IccMax" slider to max 255.55 5. in "FIVR Control" Section, select "CPU P Cache", than check in "CPU Core" Section below "Unlock Adjustable Voltage" 6. Click Apply than OK on the bottom right of FIVR window exit TS at this point and open again, you are now ready to begin undervolting, start with undervolting your CPU Core first, Click FIVR tab in "FIVR Control" Section, select "CPU Core", in "CPU Core" Section below use "Offset Voltage" slider in increment of -5mv at a time from 0, apply and run a mixed cpu gpu benchmark like 3DMARK (CB23 not sufficient!) if bench completed with no issues increment another -5mV and so on, when you reached your cpu max undervolt limit back off +5mV, once CPU Core been udervolted, you can move on to undervolting CPU P Cache using the same process, you do not need to undervolt anything else beside these two variables, on my CPU i was able to achieve -165mV on CPU Core and -150.4mV on CPU P Cache, do not try to jump to these values each CPU bin is individual! in bios you want to set ultimate performance power plan and turn Hybrid Display off, few pages back i posted step by step guide how to repaste properly, with 107c idle it sounds like you need to do a repaste before you should begin undervolting, Good Luck

for @ATAN case i love that idea (very smart!) much better than tailoring a vapor chamber solution from scratch, this can potentially smooth some spikes not having a GPU below, more copper will do the trick and that should fit right in like a glove, @1610ftw there is another heatsink design for the 7770 with more fins and a plate over the dGpu area on the top and a bigger bottom plate, with a much beefier heat pipe instead of the thinner one, if you scroll back to @Aaron44126 early images you will see it there,

@ATAN did you try LM TIM? that with bit of undervolt should do the trick (provided your silicon agrees with your undervolt), i was able to eliminate throttling on the 7670, for that i had to undervolt cpu core -165Mv and cpu p cache -150.4, at that point (actually bit before at around -120mv on p core) thermal throttling was eliminated, i could see turbo spikes up to 147w and settles around 77w after boost,

you're off your rocker mate 😄 you cant just mount random vapor chamber in a laptop chassis, to start with there's no room for one unless you hack at the existing heat pipe mount, a vapor chamber itself has to be fully incased between supporting copper plates for further heat distribution and dispassion, and preventing from any physical pressure on the chamber surface itself, you will need to combine in precision both GPU and CPU into one large chamber and have them incased, just return the unit (if possible) and look into a unit with more thermal overhead instead trying to reinventing the wheel, i had to face facts too sadly i returned my 7670 unit, it's just not my place to fix Dell engineers poor design even if it was possible,

sure have, if you scroll back few pages when i initially posted it i have also applied it myself after enabling the classic power schema back in windows, worked flawlessly no hiccups were observed and i had you in the back of my mind with the wake issue you mentioned having, couldn't replicate it here with S3 switch on, (i added two more S3 switches to the post above in case it fits your situation),

setup_var CpuSetup 0xE 0x0 # Enable ACPI S3 Support (default 0x1) setup_var CpuSetup 0x259 # Slate Mode on S3 and S4 resume (Default 0x0) setup_var CpuSetup 0x25B # Dock Mode upon S3 and S4 resume (Default 0x0)

one can also try to hunt down the specific codec missing in this case it should be HVEC which can be downloaded from Microsoft directly https://apps.microsoft.com/store/detail/hevc-video-extensions-from-device-manufacturer/9N4WGH0Z6VHQ?hl=en-us&gl=us my situation is slightly different, i have many old files from older cameras, there was no regulatory back then (still isn't), it is practically impossibly to track a 20 year old camera codec, the bundle K-Lite provides up to this point resolved any codec issues i run into,

call Dell's customer support and ask for replacement unit, plain and simple, don't try to explain why just say this unit is not working for me its overheating, i want a replacement or to return the unit, they are aware of heating issues with the 7670 and wont argue trying to save the sale by sending a new replacement asap. (i just returned two 7670 for overheating, both original order and a replacement unit went back, just put it to performance mode in bios and you will have native solid 80-90c at idle reason 😉 )

mainly increased CPU and dGpu performance, as CPU onboard gpu is disabled and iGpu becomes sort of dedicated GPU tunneling everything through it, also for control external screens assignment for iGpu or embedded gpu,

i am surprised i didn't think of this earlier, by now its a second nature i don't really think about it anymore, you most likely missing lots of codecs since its a new default system, Download and install K-Lite Codec Pack (i recommend to use Mega, select install everything option) afterwards you should be able to render your file in media player, you should also have a new media player classic 64bit & 32bit also included with Mega i suggest making 64bit variation your default, it is the good old classic media player with lots of controls never exposed in the original version, you can swap rendering engine and much more, been using it for years now, occasionally i will encounter an odd video that wont render properly, for those i also have VLC Media Player installed (not used as default), VLC adds few odd or very new codecs to the collection which will make virtually any media file render properly, (it is recommended to update these two every 6-12 months or whenever new media file doesn't render properly)

yep, change your bios power plan from balanced to performance and try again, (in windows use either power plan you like, power saver or balanced to compensate)

if my next endeavor with the 7770 wont stick i will be looking at one of these when they come out,

i am by now a certified Dell junky, i don't know when or how i ended up like this, no one warned me this Dell stuff will mess you up for good 😄 i went the Razer route while back, tried both 15 and 17, tried an Asus model as well Lenovo (wont touch MSI with a stick), i need my Dell logo proudly prancing or its not a workstation for me 😉

@Aaron44126 Thank you :) just as yourself i don't use my laptop for its "portability" its mainly stationary on my desk, occasionally ill bring it to the kitchen to watch something while i make dinner, and i never use it on my lap, i do have Samsung's CHG90 a 49" ultra wide screen taking most of my 7ft. desk space (the CHG90 is connected to a custom build Corsair ONE i160 sitting on the left of the screen), leaving me with sliver of minimal space on the right side for my laptop to coexists at a slight angle, previous generations of full size mobile Precision 17 were too big for my desk and personal taste, seeing the XPS 17" with smaller footprint than my current 15" M3800 made me a big fan of the XPS 17", even the latest 7670 with its bit odd taller screen ratio next to my old 15" still has smaller footprint, if the new 17" is an inch less wider than previous 17" generations i think i can live with that, the expandability and options under the hood with the 7770 are phenomenal and cannot be matched anywhere, if only the heat can be little better managed i would keep it, i am thinking i will give the 7770 a go with same config as with the 7670. 12950HX, 3080 Ti, 4k screen, 256GB NVME (i already have 4 2TB 970's), 8GB SODIMM module (will upgrade later with 64GB aftermarket kit), any other hardware recommendation/consideration I should make?
