Sounds great! Thats in the top 5% of for short burst CPU performance for any laptop. Sounds like a winner, especially if the Sunon fans on yours do not make that creaking noise when they cycle on.
-
The best I have seen from Dell was the Alienware 51m R2 which had an optional CPU side vapor chamber. It could easily handle higher CPU loads at lower noise as it prioritized cooling over weight and size. Even better you could purchase a binned processor from eBay or silicon lottery to overcome the issue of getting a bad BGA CPU (and keep the good one if a mobo replacement were needed). Such a machine probably was never destined to become a Precision though, as most mobile workstation users want something portable even as a DTR.

Oh wow can it resume from S3 standby reliably? 7560 had issues with that even if S3 were enabled via hidden options. Although these days with fast ssds I found using block sleep then cold booting was best as having it randomly waking in my backpack while traveling was VERY bad and not worth the risk of it baking itself.

An NH55J refresh should be "low hanging fruit" from an engineering stance, so long as Nvidia 4000 mobile designs can be dropped in with minimal modification.

From this post from Tom at XMG it sounds like Clevo did not have direct support from AMD on the AM4 laptops: https://www.reddit.com/r/XMG_gg/comments/xveejf/we_regret_to_inform_you_that_we_see_no_further/ So anything AM5 might be less likely. I think historically Intel has been a better partner with Clevo for building their DTR models. I would be happy to see one or at least a NH55J refresh with Raptor Lake support and 4070 mobile with a working MUX. Even better if they offered it in the 17 inch form factor so it could take the larger 97WH battery, have additional USB-C ports and better cooling / ventilation.

The sunon fans on the 7770 heatsink do make a creaking noise when they cycle on. I asked the support rep who sent me the replacement heatsink if we could have the fans always run at a minimal speed via a bios option.
-
Yeah it was pretty harsh. It is very upgrade friendly so appealing in that regard. Which bios version are you running from Prema? I noticed last night that a 1.07.08 is available from https://repo.palkeo.com/clevo-mirror/NH5xJNN(Q)_R(Q)_PS(Y)/ so I want to ask Eurocom if they have their variant of it as well. Too bad still no Service Manual posted with schematics.
-
It does not help that there is something about it that hurts each potential use group. Overclockers do not want it due to lack of Z690 and low CPU power cap, DTR crowd does not want it because no 128GB memory or 4x SSD slots, T&L do not want it because its thicker and heavier than most 15 inchers and not as good battery life, Gamers do not want it because its a low TDP 3070Ti without MUX/AdvOptimus.
-
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.
