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,

i have the 7670 with SODIMM module in hand, in case anyone interested it is just a module converter mounted on top of the CAMM connector, technically one could remove the SODIMM bracket converter and use a CAMM module instead,

Hello Everyone Chris here :) new member and as of last night owner of new 7670, Basic Spec: 12950HX, 256GB SSD, 8GB RAM (SODIMM Module), 4k Screen, NVidia 3080 16GB, bought my unit with minimum memory spec with intensions of populating 64GB after market set, I am currently looking at this kit www.amazon.com/dp/B0B1L2NJY6 anyone has experience upgrading memory on this platform?
