Ill add that my system is currently just the mainboard, no case, living on a test bench before i buy a custom 3d printed metal laptop chassis.
I will further enchance cooling on any 45c+ (on full load) components before installing them in a custom enclosure. One day i may test the stock temps but i never planned to use this system stock.
For the record I stripped my system day one and have only suffer one shutdown at 90w while playing a game and running cinebench in the background (i mightve also been adjusting the power cable leading for the magnetic connect that i have yet to replace to disconnect, who knows, either way I fucked up).
Using stock ram with copper heatsinks in the giving config avoided shutdowns after 30m of cinebench at a higher wattage(although the cooler can barely sustain 90w, try 75w, your warranty is void regardless).
Memory wise I still have yet to test if there is a 1.1v lockout like on the um790. Ive only been in the amd ocing settings which it always has these settings. 6400mhz ram comes in tomorrow, even if it doesnt do 6400mhz the kit has 40-40-40 timings at 5600mhz so its better regardless. Rip no xmp or amd eq.
Currently my igpu is not showing up in windows and my new oculink cable came in so ill be testing that instead, because I know my 6900xt's drivers are stable. m.2 4.0 egpu via adtlink worked perfect once I dissabled the amd 780m oem/test driver that came with it(in the GTR7 DRIVERS provided by beelink). Im sure I can use both but windows woes.
I am designing the last parts of the build, ie battery charger (for 29.2v, 8 cells, 19.2v is 6, wouldve been easier to find chargers for and less conversion) i prefered my final choice of 8 specific cells for 102wh instead of 86wh (6 cells 19.2v, same-ish footprint), a custom cpu cooler than can handle 200w(mainly for the next build so I dont have to build a slightly similar one again), building the keyboard in the most efficient configuration (split ortholinear, choc(kalih slim) keyswitch/cap, custom trackpad and lenovo trackpoint, a few extra mouse related buttons, 3 low profile encoders, preferably within 15mm thickness if not 13mm). But its in the 90%+ of completion range design wise. Parts otw, soldering to be started soon. Hardest part is my reverse swiviel monitor mount. I want to fold it backwards but not with the screen facing down, 120hz 4k oled whist is relavtively cheap is still $200 too much to be risky a dirty surface touching the screen. So far Im planning to jerry rig two laptop monitor mounts to get this range of motion in a relatively small package, because making my own cast, cut or forged, will cost as much as the whole enclosure being 3d metal printed.
As far as power a minibox openups and smartdcdc both running a 19v rail, the open ups being a secondary bms, handling charging(albeit slow but at 29.2v even 3 amps isnt that bad), and reporting it to windows, the minibox smart dcdc giving more stable amperage to said rail, being ran by scripts(ie voltage dropped 0.1v sustained for x time, shutdown dcdc and send off signal to either a microcontroller or straight to the openups, there are too many ways to accomplish this safely and im not breaking it all down here). The system im setting up can output over 250w into 19v, 120w for this system(the openups can do that alone) and 175w+ for strix point (16c zen 4, 40cu rdna 3.5, amd monster apu of next gen, dcdc needed for additional sustained current) the openups and dcdc systems can be ran up to 30v, and buck for output down to my needed 19v.
