holly molly 😮, i know it! (was so excited i missed your TDP reading)

YaY \ o / Thank you Aaron ❤️ good call on the graphics switch in bios, i turned it off as it boosts a good amount of cpu performance (almost 16k on 3DMARK), i will switch it back on for the flash phase (i think in low bios regardless it will still switch but better safe than sorry), i have already dumped my vbios, before i re-flash can you confirm our DTP are different in nvidia control panel? (i have 125w limit atm)

Thank you Aaron, you're absolutely right i forgot it did the same to me here, i ended up using NVIDIA NVFlash tool to dump my vbios (will be used to reflash vbios too), dump command is simple from current dir run > nvflash64 --save Dell7770.rom (to re-flash it should be > nvflash64 --protectoff Dell7770.rom) did you check your current GPU TDP in nvidia control panel? (system info bottom left corner) these are fairly rare nvidia chips (10DE:2420) only shared with a handful of high end systems atm, Lenovo and MSI have these in their workstations with unrestricted 3080 Ti 16gb vbios with 155w top limit and 165W boost, i was unable to locate these anywhere atm,

bump... anyone can confirm the above and share their vbios off the 7770 for further testing? i have managed to get the 7670 cpu to around 15.6k on 3DMARK (no undervolt yet), for some reason (which i believe i found) gpu performance will not budge much from 9.6k, which keeps 3DMARK overall score low for gpu side and the system as a whole, two days ago my cpu also wouldn't budge above 9k score which been moved to 14k score now, but the gpu is dragging its feet atm and the only way to unleash the full potential is to remove the 125w TDP restriction which about 40w of performance are withheld atm to fully unleash the 7x70 platform,

anyone knows where to find a Higher TDP vbios for the Dell RTX 3080 Ti 16 GB Mobile? (Device ID: 10DE 2420 0B2A1028) i think the 7670 3080 has a lower TDP (125w) than the 7770 3080, (to check GPU's power limit in Nvidia Control Panel click System Information in the bottom left) anyone here with the 7770 and 3080 Ti 16gb can share their vbios please? (open gpu-z where it reads "BIOS Version" to the right there's an arrow, click and select save to file)

keep at it you will eventually get there, to bridge the remaining gap you see atm you will need to further dial your system services etc. repasting and undervolting will not get you there alone, my system after im done tweaking it idles with 45-50 process which is ideal conditions for my environment (beside the fact that im a control freak who lived in the days when PC actually meant Personal Computer not todays PC (Public Computer) nonsense we have now),

the way you put the heat pipe part pack in place after repasting is key for a good even spread, here is how I go about it... carefully move the part into place but keep it an inch above the board, locate your screws and align them to the board screw holes than gently place the part in place, make sure all screws are perfectly aligned, with one hand place gentle pressure on the cpu plate, when I say gentle I mean gentle as you don't want to put pressure on the board just to hold the part in place, next step is key, screw the heat pipes screws slowly counter clock wise until you hear a click then stop, that click is the screw jumping out of its thread as its being screwed outwards, with your hand keeping gentle pressure, go around from 1 to 8 and perform the same step stopping exactly at the click for each screw, do not move your plate holding hand or change the pressure, this will position every screw perfectly ready to be threaded back in, next go around each screw from 1 to 8 and turn/thread each screw a 1/4 turn in (keeping the gentle pressure on the cpu plate until the process is complete), than rinse and repeat... keep turning a 1/4 turn for each screw in its turn until they are all fully threaded in and tightened, by the end you have slowly lowered the plate into contact as even as possible, after the 8 main screws are in place put the 4 fans screws in any order you like, (note that when initially positioning the plate it is high enough that any paste on it should not be touching yet until the plate is fully lowered) I use painters tape around the gpu and cpu during pasting phase (before marrying the top plate), I don't just put a spot in the center I actually spread the paste evenly on both the cpu and gpu silicon die, I use a generous amount but not too much, just enough to get an even coverage without being "cheap", I than remove the tape from around the cpu and gpu so i get a clean paste area ready to be mounted,

i was able to reach 24.6k with kryonaut only, granted i do allot of other tweaking to the system, do you monitor your temps during CB runs, are you throttling?

@ATAN did you apply @win32asmguy loadline tweak?

id be curious to learn where you are now on 3Dmark, i think part of my score issues is running only one memory channel with my one 8GB stick atm,

anyone recorded default setup values for IA AC/DC LoadLine tweak?

"you take the good you take the bad and there you have the facts of life" out of curiosity i run 3DMARK bench on the 7670 to my surprise despite the high CB scores the system is scoring very low in real world tests, so low it is having a hard time even reaching the 60% performance mark other same cpu score show, despite my efforts the system score on 3DMARK remains poor and cannot reach even the average score, for this cpu family 3DMARK is reporting a score of roughly 14k as the highest, 13k is average, my system can barely reach a 9k score atm, it doesn't seem to matter which power plan is in play nor any undervolt settings seem to make any difference nudging the score there, these results basically summarizes everything we all been reporting on this thread, thermals on this unit are not great to say the least,

the amount of cooper used is significant and makes this part relatively expensive, apparently thermals is the only corner left to cut in the already pricy Precision line, @1610ftw i think i mentioned the cpu (sorry i messed up the model earlier), i did the generic benchmark everyone runs, i think it was time spy, it was XPS 9710 with i9 11980HK RTX 3060 on Win11 undervolt settings for that unit were shared on Linus tech Tips forums here

Dell as far as i remember always had top notch engineering and always ahead of the curve when it comes to design, whoever signed off on this designed should be fired along with similar creepy minded executive concerned with cutting corners for their personal bonuses, that is not the good old Dell spirit I know and remember, that newly spreading mentality the past few years should be nipped at the bud.

having a hard time seeing this heat pipe design running HX CPU with additional 8 cores, something has to change,

you don't think they will change the 7x prefix to 8x with a new vapor chamber design? (pls no bubble buts) hmm... i donno you were way off on the 7570 there

like yourself I've been waiting for several years now for the perfect platform to move on to the next few years, i was elated with my 7670 specs and looking forward to falling in love with it, then Jensen announced his new GPU, and Intel with their new CPU's and faster DDR5, i felt like a rookie who didn't do his homework when i learned these were coming out shortly, ouch, i don't know that i want to wait another year for the next iteration,

@1610ftw i worked at getting that score it didn't just fall out of the sky, its a fun habit of mine to see how far a certain pc can be pushed, there's allot more that goes into this, undervolting is the least and last tweaking element in my setup, i recently had 11900HK XPS 17 i also dialed in to the highest score on 3DMARK, you can check you will see my handle name with highest score next to it for that cpu, i returned that unit and got this instead, initially i got a great deal on a refurbished XPS 17 unit, when it arrived there were allot of scuffs and dings all over and the worst part the screen had a wobble, i could fit my fingernail between the screen back shell and the screen itself, cosmetics aside i did my thing with that unit too just to see what its potential is, i have to admit i loved that unit and would have kept it if it wasn't botched or if Dell offered an exact replacement, long story short i was always eyeballing the 7670 upcoming line as soon as they were out i was ready to order, but they didn't have the sodimm module available so i waited until it finally became available and placed my order, two weeks into me waiting for my order to be built with top of the line specs, NVidia comes out with Lovelace architecture showing effectively twice the performance from previous generation, followed by Intel announcing and releasing Raptor Lake architecture with additional 8 E-Cores and faster DDR5 support, i just specked a brand new system with top of the line components and two weeks later before i even get to enjoy it its already old news hardware wise, i usually commit 5-10 years with each personal laptop driver i don't like switching, if this machine didn't have issues i would have kept it, but it does have issue, the high CB score comes with unmanaged heat premium that throttles, i am not fully comfortable committing the next 10 years to this unit, i don't feel thermal design in this unit is sufficient or robust enough to host the HX CPU line, i will be waiting for the upcoming 8x80 line with the hope they design it with proper vapor chamber that can manage demanding thermals, if they keep this flimsy heat pipe design for the new Intel Raptor lake CPU's i will reluctantly look into a Razer Blade solution instead, to be fair and to DELL's credit and true fashion... before i started tinkering with this unit i already called them to complain about idling at 76c and few other anomalies i observed with this particular unit, they immediately offered a complete brand new replacement which i agreed too, its one of the reasons i am addicted to DELL for over 22 years now, and why i bought and supported hundred of thousands of their machines over the years, a replacement is on its way, i have not yet fully walked away from the 7670, we will see.

i find it hard to believe, either way that's an application level issue not a system wide or remotely close to be an issue! indeed you can set your final undervolt setting directly in bios with setup_var so it is low level implementation and permanent, i still fail to make a logic connection how virtualization effects TS, i have these settings for my system if you want me to post (look for "Voltage Offset" in bios dump),

i am running everything thus far with a single 8GB SODIMM stick which puts the system in single channel mode, makes me wonder how much more can the system improve in dual channel mode

nop you did not, i am not @Aaron44126 😄 follow hyper links i added to this post they will take you back to all previous posts containing info relevant to undervolting the 7x70 platform

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
