Reset the thing because I suspected installing drivers from the Metabox website package was the start of some screwy stuff. Default windows drivers only now. iGPU still locked at 300mhz and requires "overclock" (will set up XTU command line to profile load to run at startup) but the speaker crackling is gone by reducing quality from "Studio" to "CD quality" (16bit 48KHz) in windows settings. A nice inconvenience fixed and its not like the speakers are anywhere near good enough to notice the difference ...

I figured out the issue with general Windows stuttering under Advanced Optimus. The UHD 770 iGPU is not boosting above 300MHz. 300MHz is enough for about a 720p youtube vid but causes 100% utilisation and dropped frames at higher res e.g. 1080p60, or Google Earth, or causes lag when dragging or scrolling complex elements on the screen. To fix this, I installed XTU, set the igpu voltages to the minimum available (UV protection didn't allow OC on default voltages), set the ratio to x14 for 1400mhz, and iGPU util% dropped far below 100ish% and all the dropped frames on yt went away. Power consumption was barely affected at all. (the two hwinfo screenshots show a before & after on the same 1080p yt vid that was dropping frames at 300mhz. These were just the first settings I tried and further tuning I'm sure will refine it) But basically the point is, this laptop was sold with Advanced Optimus disabled in the BIOS, and I've seen loads of reports of 'stuttering' with it enabled from various resellers, and here I think is the explanation for that.

Is anyone willing to admit they own a X370? I can't even see an owners thread I picked up a X370SNW-G (Metabox Prime VR) cheap on ebay (cheap compared to what its original spec would have cost - 13900HX, 4090M, 64Gb and 4Tb SSD) knowing the cooling was bad but with some mods in mind. And yes the cooling is bad and the fans are horribly loud and it gets hot on the chassis above the side vents and the bottom RAM stick goes above 85C and I have had to underclock both CPU (4.5ghz max) and GPU (0.8V / 2000mhz) to be able to watch TV in a room while using it and Advanced Optimus causes minor stuttering in Windows and the Clevo Control Center doesn't allow fans to go below 30% dutycycle which is too loud so I use ClevoFanControl which can set them to 23% but keeps waking the GPU and the speakers are rubbish and I get audio crackle as soon as I install a Realtek driver and the caps on the keyboard are all wobbly and loose Aside from that it's nice to be back to a 17" UHD screen after a couple years on more midrange QHD laptops and its less noisy at these settings for more pixels and fps than the i9/4060 Helios Neo 16 on which I have had to redo the liquid metal 3x now in about 20 months of ownership. I had my P870 on my lap the other day and the stand dug into my legs after 15mins, I forgot how heavy that thing was! (6kg with all the extra stuff from my watercooling mod) To be honest this feels very similar to the Helios and that's both good and bad... I actually really like the quality and materials of the Helios chassis, but can you imagine the howls of rage if I said a decade ago on NBR to the never-BGA crowd that one day Clevo's high end would be on par with a midrange Acer.......

price difference is also huge. $5000 for Clevo X370 w/ 4080 in Aus dollars. (+$1500 for 4090!) I could recoup some of that by parting this, 9900K, 2x 1080s, 4x16Gb 3000MHz RAM still have some value. It will just be incredibly insulting to be buying only 4070/4070Ti desktop performance for well beyond actual 4090 money. I guess nobody has yet put a 3080 into DM3?

Is a 3080 from X170 going to work in a P870DM3? Re electrical/firmware compatibility Modding a heatsink is not a concern I currently have Prema EC code and Dsanke BIOS (his original pre-Spectre one for my P0 stepping 9900K) Just looking ahead. 40 series is underwhelming and/or horrifically expensive, and if Dragon Range ends up being a damp squib I think finding one of these will be the next least rubbish option
-
3070 looks more promising tbh, the lower power limit on the 3080 (due to the extra memory chips?) will hurt clocks but yeah, who feels lucky going for one of these

clevo We did it. TM1 heatsink has been grafted to KM1

about 170W. I have had to raise various secondary power limits in the prema bios to get that high without throttle, it was a long process to find what to raise to get rid of the eDP throttle flags on this DM3 (and the older DM 6700K also with premabios to go beyond 4.6ghz). Tbh I forget exactly which settings I raised iirc it was input current related. This 9900K can handle 4.9 with a -25mV offset so the headroom is there but there's a hardware limit that causes instant shutoff that gets triggered beyond 170W so do all my testing with power and iccmax limits in place Cooling is the main problem, I had to make my own heatsink with extra heatpipes and a waterblock on top adding hybrid watercooling to handle 9900K @ 4.9ghz/150W. I don't bother stress testing AVX anymore I hardly ever use it, just set and forget with a -3 offset. I stress for stability using x264/x265 as I do have to encode semi regularly. -
ugh. Horrible news I guess with the silly prices of new cards in general the DTR niche and aftermarket MXM mod scene is deader than ever. I'd risk maybe $1k on a 3080 MXM to see if it worked with the possibility of getting most of it back if it didn't At least we have eGPU as a fallback and we just have to hope we can hack the power limits on CPUs to keep them interesting for those of us with exotic cooling methods (Speaking of which, I'm fixing up my watercooled P870DM3 at the moment, I better be super careful)
