Ah, what is the likelyhood to order one of these to USA? Be happy to test out something that is an improvement over the stock radiator!
-
Also useful for M.2 eGPU adapters. It has great bandwidth with none of the latency overhead of thunderbolt and easy access with the door.

We might try using RW Everything to monitor EC memory area and see if some addresses map to fan speed control. That is essentially how MSI implements their fan control (and interfaces to it via their GUI software), so you can write six Temperature Threshold + Fan Duty combination values for each fan. You can see more about this mapping table I described here: https://github.com/YoyPa/isw/wiki/MSI-G-laptop-EC---Rosetta Its just a hunch but if things have changed from their previous implementation the new design may be accessible via the EC memory area now.
-
Ah, good point. The bios may be adhering to those hidden settings or even the power plan fan policy. In the past I think the Dell EC ignored them and used a custom hard coded curve based on which of the four dell performance modes you were in. One of my biggest pet peeves about laptops is that virtually no manufacturer has bios options for custom fan curves similar to what you would find even on a cheap $150 desktop motherboard. The only exception to it is system76 which allows you flash a customized EC with user defined fan curves to certain models they offer.
-
I am just glad we were able to improve things up from the initial worse multi core results. I still wish we had a bios option to force the fans to run at a minimum speed on AC power!

I think Nvidia does not support the Geforce GPU's under Linux, at least not in a capacity where if a bug is reported with their driver they guarantee any timetable for a fix. As far as unofficial support I have found the cards work as good as most other gaming laptops with the same card. I have not tried Ubuntu but could maybe try swapping SSD's over the weekend and doing a quick install to see if it has the same issue compared to Fedora 36 with 5.19.13.

Its the pro version of the GT77. No light bar on the back and the keyboard is membrane instead of mechanical so its very quiet. It also has a decent three year onsite warranty included for the price which is great as the previous MSI workstation laptops were mail in only. Of all the workstation devices this one has the best bios as everything is accessible via the advanced unlock. Oh, and it also has modular wifi, and the ethernet is 2.5g. Also it supports S3 sleep which is less likely to randomly wake while traveling or otherwise.

Yeah, the Precision is probably not the best choice if you need closest to desktop CPU performance. I am also testing a MSI CreatorPro X17 with a 12900HX and it can score up to 25,500 in CBR23 with max fans enabled.
-
Fedora 36 with Kernel 5.19 has been working pretty well for me on the Precision 7770 with xorg+intel only. There was an issue with 5.19.12 that broke the iGPU driver (black screen with flickering) for 11th and 12th gen laptops, but that has been fixed with 5.19.13. Is that the issue you experienced? As far as Linux laptop experiences go the Precision is pretty good, other than the fact that it only support Modern Standby which I have to deactivate via the Block Sleep bios option.

The part number is RPD7J from the packing list. If you do order one be sure to also check each thermal pad and ensure they are sitting squarely in place, and try to only do 1-2 turns on each screw in the pattern until they all bottom out.
-
I am not sure if there was a bad batch but I did not mind trying to replace mine as it was easy to order and install myself. I am happy the new replacement heatsink has higher quality thermal compound on the CPU side. Its a sad thing that there are some reported issues but the tolerances are only tighter on this generation of products so its not something easy to get perfect on the first try. There is still not another option out there with 17 inch FHD, 12900HX, Windows 10 support, 3080Ti GPU, and generally professional aesthetics.
-
I am not sure about the 7670 capabilities, but for the 7770 my performance issues were fixed with a replacement heatsink. It can now get over 22,000 CBR23 with stock pads and thermal material and no undervolting.
-
Did Prema get you a modded bios with Raptor Lake microcode injected? If so you could try it on launch day. Additional e-cores and larger cache means the P-cores will be even more power starved than Alder Lake at 125W unless they have seriously improved efficiency. Although it would be pretty cool to see 5.5-5.6ghz single P-core boost in a laptop with that chip if its possible.
-
I used the stock pads. I did straighten a couple of them just to make sure they would sit squarely on the component and not cause the heatsink to lift off of the CPU. Thanks for the heads up on the bios. I want to check and see if they silently fixed the IA AC/DC loadline values with the update as well.
-
I ordered the pad version. Lenovo does seem to have had success with using it. If anything it seems to have a more consistent result from the factory. Also to rule out the heatsink I ordered a replacement from Dell. It took about 30 minutes of troubleshooting then they sent an overnight parts dispatch. The new heatsink has Sunon fans instead of Delta. The specs are slightly different on the fans (Sunon, 5v, 0.8a, 9.4cfm) vs (Delta, 5v 0.5a, 9.2cfm) and they have a different sound cycling on/off which is quieter. The stock TIM also appears to be better than what was shipped originally from the factory, I will use it this week to see how it performs. This one is already exceeding what was sustainable with the original.

The Strix is great for gaming performance, noise and built in audio. I didn't like the overly gamer design, lack of webcam, port selection and honestly no FHD panel option. The NH55J is great for CPU performance, good aesthetics. I didn't like the audio (especially lack of Windows 10 driver support) or the fact that it has a 15 inch screen. Even with tuning it is noisier than I prefer and has random noise spikes. Battery life isn't great but it can usually last through a longer meeting. The Dell has the best build quality, aesthetics, keyboard, webcam, battery life and support. The performance is low but is a work in progress. The price is about the same as the Strix if you do not factor in the warranty upgrade cost. It is also the quietest of the bunch just because of the way the fans are tuned and its thickness. The port selection is amazing, all laptops should USB-C and USB-A on both sides.

What would have been wrong with Clevo refreshing the X170 with Z690 + DDR4, and stick with the existing 3060/3070/3080 MXM lineup? I am annoyed Nvidia holds this double standard. I have a Precision 7770 with a modular 3080 Ti mobile chip, if they allow Dell to make this, then they should allow Clevo as well. Or maybe they made some requirement like "modular Geforce only allowed if Quadro cards also used". What a bunch of crap.
-
Maybe one of the panel manufacturers Lenovo uses has a Gsync bug? Iirc they use BOE, CSOT/TCL and AUO for that panel.
-
This machine is definitely more challenging to tune. Over the course of a week the temperature deltas had grown by another 10C (71C coldest, 100C warmest) so I pulled the heatsink back off and it appears the paste had pumped out. Repasted and reassembled and its back to where it was before. I am also ordering some Honeywell PTM7950 from China which is supposed to be more resistant to pump out and offer better thermal transfer.
-
Maybe this is helpful? https://www.techpowerup.com/review/intel-core-i9-12900k-e-cores-only-performance/7.html Granted, the e-cores are subject to the same silicon lottery as P-cores so an excellent or poor sample could inaccurately represent what to expect. They are probably not as efficient at 3.9ghz in the 12900k as they are at 3.4ghz as well, so maybe more testing would be good using a system that can freely adjust the multiplier range. That being said I think the battery life is pretty good on the Precision so long as you take steps to ensure the Nvidia GPU is not activated unless it is needed. You can create a power mode for battery with P-core turbo limited to 4.0-4.2ghz which is definitely in the sweet spot of their efficiency.

I mostly only did the CPU side because of these reasons: Ran out of time and wanted to just get it reassembled Lack of proper tools (really need plastic tweezers and scissors / cutting knife and mat to properly create the custom pads) No good resource of guides (tried looking back into NBR archives for that, or youtube) Issues with eyesight and lighting I think going back and doing the GPU side is a good idea as Nvidia has a sliding clockspeed scale depending on temperatures, so a core at 60C will benchmark faster than a core at 75C even if its not technically thermally throttling. If I remember correctly HID Evolution used to offer CTO Precisions through their repaste / repad services. It could be quite valuable if a turn key "excellent" job is required.
-
I was curious where you purchased these bricks? Eurocom wants 250USD for these which is quite a bit.
-
Yeah, unfortunately it still cannot be sustained at that level. It eventually settles back to 85W scoring about ~18500 in each CBR23 loop and still thermal throttling with P-core temp deltas still 16C. This model is worth tuning as it is the only option with HX cpu, 17 inch FHD display, 3080ti, Windows 10 support and a TB4 port mux. It also gets over 8 hours of battery life in light usage scenarios with my config so its also superior to the Clevo NH55J in that regard. The only downside is that only modern standby is supported so I have that disabled and only completely power off the machine or use hibernate.
-
I replaced the thermal pads today on the CPU side with some mid grade 12.8W/mK and now performance has jumped over 15%, CBR23 Multi scores without undervolting was 20634 with e-cores enabled. This was with Phobya Nanogrease Extreme. I did not do exactly a great job with the repad. My vision is not great these days nor my ability to make the precision cuts and hold them steady dropping into place, but this is still a great improvement over the factory job. I will post an image with the pad thicknesses marked later. Aaron I hope you do not mind me borrowing the photo you took for the pad measurements.
-
I enabled undervolting and tested -75mV P-core and P-cache, which scored 14750 CBR23 with e-cores disabled at 75W pull.
