The iGPU is determined by the CPU. You'd have to complain to Intel about this. They use the same iGPU in all Alder Lake HX CPUs. (Well, aside from 12450HX which gets only half of the EUs compared to the rest.) The iGPU in Alder Lake HX does use the same Xe graphics architecture used in the Alder Lake H CPUs. It is just 32 EUs, compared to 64 or 96 in the Alder Lake H CPUs that they have labeled as "Iris" graphics.

Went and ran 3DMark Time Spy against the integrated Intel GPU. The result that I got was a brilliant... 855. What I was interested in here mostly is how well the iGPU compares to the best dGPU from ten years ago. My Precision 7770 replaced a 10-year-old Precision M6700, which originally shipped with a Quadro K5000M GPU. The K5000M (at stock clocks) was able to get 6.37 FPS on graphics test 1 and 5.60 FPS on graphics test 2. So, the Alder Lake HX iGPU is sitting at just about exactly 75% performance compared to the 10-year-old Quadro K5000M. Presumably, an Alder Lake H iGPU (with 3× the execution units compared to HX) would be able to beat it.

There is something messed up with Optimus on my system. The dGPU remains powered on even though nothing is using it. That can raise temps. (I don’t know if it even uses the lowest power state in this case.) This probably is affecting other users as well; it’s been a pretty common complaint since Precision 7X30. To fix it, I basically… Log into Windows and wait about a minute. Go to Device Manager, disable the dGPU and enable it again. All good now. (Must be done at every reboot. I have it scripted.) Note that the NVIDIA tray status icon shows gray/off even though the dGPU is on. You can check to see if the dGPU is “really” off by running a separate tool to check its power use or temperature.

Depends how far back you want to look. The Linux code was derived from some DOS-based diagnostic utility — from Dell themselves — that someone reverse-engineered. It's my impression that the old controls are gone. Dell has revamped how fan control works. ...That said, I am totally interested in hearing if anyone on the Linux side figures out fan control because I think that I would be able to reproduce it on Windows.

I am not using ThrottleStop, but have you checked to make sure that the virtualization features are disabled in BIOS setup?

I don't really know, I have never bothered with discharging the battery before disconnecting, and I have never seen a Dell tech do this either...

You can remove the bezel easily. Tilt the screen open as far as it will go. Start with the outside edge of one of the bottom corners and then just work your way around. I have a Precision 7530 sitting right here and I was able to get it started with just my fingernail. A pry tool would probably be best so that you can avoid bending the plastic too much as you work your way around (it can snap and break), but I have done it by hand without issue on multiple systems.

Elon Musk seems chummy with Tim Cook now. https://www.theverge.com/2022/11/30/23487040/elon-musk-tim-cook-apple-threatening-twitter Trouble in the EU. https://arstechnica.com/tech-policy/2022/11/twitter-claims-none-of-our-policies-have-changed-after-abandoning-covid-policy/

Yeah, so here I am just referring to the sound when the fans first power on. My Precision 7560 is silent, you can't hear them spin up. My Precision 7770 fans start with an obvious whirring noise. You can hear it when you power on the system from a cold start using the power button (in addition to when they cycle on and off during normal operation). ———————— I just updated to BIOS 1.7.1, no issues so far.

I haven’t had flickering, except when trying to run with graphics switching disabled. I have had the really slow behavior once. I finally got Task Manager to open and found the CPU capped at 0.39 GHz. It was solved just by unplugging and replugging the PSU. If I got a system that behaved like that out of the box, it’d go right back…

Twitter Blue launch delayed while Elon Musk figures out a way around Apple's 30% cut for in-app purchases. https://arstechnica.com/tech-policy/2022/11/musk-wont-relaunch-twitter-blue-until-he-finds-a-way-to-avoid-apple-fees/ (Hint: Just make people use a web browser to sign up.) (Also: Google charges the same fee.)

I think it's basically just a matter of display bandwidth. Dell doesn't set particular resolutions as allowed or not allowed. That's more up to the GPU driver. Precision 7710 can output to a 4K display at 60 Hz. (I have personally done this on Precision 7510, both over mDP and through the TB16 dock. WD15 dock can drive it only at 30 Hz.) 4K is approx. 8.3 megapixels. Your ultrawide display is just 7.4 megapixels. The bandwidth is there. I think it should work.

Weird. I've definitely pulled the Precision 7530 bezel off and put it back on and it should be the same part as the one in Precision 7540. Be careful when you are pulling it off and you should be fine. (It is pretty easy to break if you bend it too much.)

Buying panels is tricky, for sure. This is a seven-year-old system and the panel that it originally shipped with is likely not manufactured anymore. I remember trying to get a replacement LG 1080p panel for Precision M6700 when that system was 6-7 years old, and it was impossible. I got an AUO panel from someone that worked as a replacement, but I ended up sending it back because the display quality was poor. A lot of sellers offer "compatible replacements" so as you note it might not be clear what you're actually going to get. They may work, but with lower quality than the old panel or pixel issues. (Most sellers won't guarantee zero dead/stuck pixels, and will even complain that is a ridiculous standard to meet when pressed... though Dell does make that guarantee themselves. It makes me think that they are getting reject panels that weren't sold in laptops because they have a defect. I'd happily pay a bit extra to guarantee no pixel issues if I needed a new panel.)

Replacing the display panel is even easier than that. You just need to pry off the display bezel, undo a few screws to free the panel, and then remove the display cable from the back of the panel (attached with both a clip and some tape). Despite what the manual says, there is no need to remove the bottom cover and detach anything from the motherboard (other than the battery maybe, just for safety?). I've done this multiple times with Precision M6700 and Precision 7510, and once with Precision 7530 and Precision 7560. To enable integrated graphics, just pull the coin-cell battery to reset BIOS settings to default and that will do it. You can also get into the BIOS without a working internal display. Connect an external display, mouse and keyboard; then, power on the laptop and quickly shut the lid. It should run the BIOS screens on the external display.

You can remove the bracket from the old card; you might need a heat gun or hair dryer to heat it up to get the adhesive to release. (You will need something to hold it in place while you mount the card in your new system until the heatsink has it screwed in. The adhesive that is sort of still stuck to it when you remove it might be good enough.)

I dabble in cryptocurrency a bit and was lucky to not have any wallets at FTX. This is another "fascinating to watch" situation. It's still rather unclear what happened. (Granted, I haven't been following this one as close as I have the Elon Musk / Twitter situation.) Clearly there was mismanagement going on, but rather it was "intentional fraud" or just "gross negligence" (combined with some losses from hackers) isn't clear to me. Sort of stinks for people who either unable to withdraw their funds or just had their portfolio drop in value (more). Like @Reciever, I'm not in a position where I have to sell anything, so I'll just continue to hold for now and see what happens. I'm good playing the long game. The cryptocurrency market is generally (wildly) unpredictable so who knows where we will be in another few years.

Nice, not a bad deal... The card "belongs" in this system so no INF mod nonsense this time right?

Well. A new update was posted, 1.9.8.6.

Apple reportedly has concerns over the state of content moderation on Twitter. It could risk getting pulled from the App Store. (It would be at similar risk of being pulled from Google Play...) https://www.macrumors.com/2022/11/28/elon-musk-apple-stopped-twitter-ads/ https://www.theverge.com/2022/11/28/23482387/elon-musk-twitter-apple-threat-withhold-app-store The "source" is Elon Musk himself, so who knows what is really going on, but... For precedent, Parler was temporarily yanked from both stores after failing to deal with violent content in the wake of the January 6 2021 event, and Truth Social had a difficulty launching on Google Play over content moderation concerns. Further back, Tumblr was temporarily removed from the app store in 2018 also because of content moderation issues. With Twitter's content moderation teams gutted, it's been widely reported that they've had a hard time keeping up. If Twitter gets pulled, Musk's solution is to create an "alternative phone"; Twitter certainly has the resources for that, right?

That's a bit better than I got on mine out of the box. I'd still recommend the IA AC/DC loadline fix, it is the easiest substantial performance boost for these systems and it will help for "idle" thermals as well. The directions are in the very first post in this thread, see number "3". (No hardware modification necessary.) It would likely push you up into the 18000 range.

Macrium Reflect free edition is going away. They will offer security updates through early 2024 but no other features & fixes. On the plus side, Macrium Reflect Home is 50% off right now (both single licenses and four-pack licenses) so I'm going to go ahead and purchase that right now.

(Speculation) If you're hitting power limits, the iGPU would also consume some power, so cutting it off could give a bit more headroom for the CPU to just do "computing".

Fair enough. Dell doesn't, for example, stick new workstation GPUs in an existing Precision laptop if something new becomes available "between" generations. I don't consider this to be a big issue. The yearly refresh means that you won't be waiting for that long. (Also, Intel and NVIDIA have recently sort-of aligned laptop CPU/GPU upgrades for "mid-winter", at least if you don't need "HX" CPUs; so CPUs and GPUs upgrading separately might be taking a break for the next few years.) I also agree that there are more gaming laptop users than mobile workstation users out there. I wish gaming laptop makers would offer laptops with a broader feature set (i.e. 4 NVMe slots! numeric keypad!) and a more "normal laptop" appearance — I think they'd find a market for individuals (like us) who want a high-spec laptop not necessarily just for gaming, and tend to gravitate to business-focused mobile workstations because there aren't really any other choices.
