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

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,
