    Was it a problem with supporting the laptop on linux, or the docking station? What model? Was it ever fixed?
  2. Conan11
    This would make sense. The fans are supposed to circulate the air through the chassis, thus in addition to transferring heat via heatpipes to the fans, some of it can be removed directly from where the heat sources are. That's of course me guessing based on the advertising materials.

    Thanks. The thread is quite long now, and I jumped in in the middle, missed that. 2TB+4TB+2TB could be an interesting option for 7670!

    What RAID levels are supported? 7770 specs pdf mentions only RAID 10. Can one configure RAID 1, or two pairs of RAID 1?
  5. Conan11
    How do you know it (other that you happen to own 7560)? In this page: https://www.dell.com/en-us/work/shop/dell-laptops-and-notebooks/precision-7560-workstation/spd/precision-15-7560-laptop/xctop756015us_vp They clearly offer to get all drives Gen4. False advertising?
  6. Conan11
    Is it true? They offer laptops with all drives being Gen4.
  7. Conan11
    Does it concern only the mechanical size of the drive, or are there other limitations? Perhaps you can judge if the drive would fit just from looking at the slot? It might be hard to see on the photo, but if you own the laptop you can check to avoid buying wrong drive?
  8. Conan11
    How do you find out that a laptop supports only single sided drive?
  9. Conan11
    Thanks for the explanation. But that's what I was confused about. I was wondering why the choice is limited to three processors which support ECC, when ECC memory is not actually available.
  10. Conan11
    Excuse me, what leaks? From what I see in the specs selection of ECC CAMM modules is quite limited, perhaps they need time for that. But they support also DDR5 SODIMMs, and they are already an improvement from DDR4. Or do you need to select which memory type do you want, and you can't change it later? Does this mean the new 7770 does not support SODIMMs yet?

    But if I configure the laptop with the cheapest, 2230 SSD, I think I need a different heatsink for a new 2280 card? Or does the same heatsink fit both sizes?
  12. Conan11
    Ah right, BOE NV15N4R 200 Hz: https://laptopmedia.com/screen/boe-66xpp-nv15n4r-boe08cf/ while B156HANsomething no PWM: https://laptopmedia.com/screen/auo-5ng4m-b156han-auo3892/ https://laptopmedia.com/screen/auo-k1mp9-b156han-auo23ed/ I have no idea! So far I was lucky to get panels without PWM, and I want to take care of my health in general. I have 250 Hz on my phone and it's fine, but I spend much less time with the phone than with the computer.
  13. Conan11
    I think the main challenge with SSDs is getting the heatsinks, which DELL doesn't seem to sell individually? But I can see them available on amazon, so perhaps that's not so much trouble?
  14. Conan11
    I wonder how these screens perform in terms of PWM? I tried to look at reviews of some recent Precision models, but I don't see a clear pattern. The two bad examples are 5540 OLED, which uses 241 Hz PWM below 50%, and 7560 IPS uses 196 Hz below 100%. I wish the manufacturers gave those specs out (or better, did it right). This makes me reluctant about getting the newest, non-reviewed model. https://www.notebookcheck.net/Dell-Precision-5540-in-Review-Workstation-Doubles-as-a-Hand-Warmer.443886.0.html#toc-4 https://laptopmedia.com/review/dell-precision-15-7560/#pwm-screen-flickering https://laptopmedia.com/top-laptop-pwm-ranking-rated-by-negative-impact-on-eyesight/#Dell https://www.notebookcheck.net/PWM-Ranking-Notebooks-Smartphones-and-Tablets-with-PWM.163979.0.html?
  15. Conan11
    Ah, thanks for the answers. Yeah, I definitely would be fine to replace the components manually to save $1000.

    What's up with Dell prices of memory and storage? Looking at Precision 5560 page, upgrade from 1x8 to 2×32GB RAM is $680. Same spec RAM from Kingston: 2×130 = $260 2TB SDD at DELL: $780, while at Samsung it's $270, WD $240. Am I missing something about the specs or quality? You could buy RAM from Kingston and Samsung, then buy another set of spares, and that would be still cheaper than what Dell charges. https://www.cdw.com/product/kingston-valueram-ddr4-module-32-gb-so-dimm-260-pin-3200-mhz-pc/6245626?pfm=srh https://www.samsung.com/us/computing/memory-storage/solid-state-drives/980-pro-pcie-4-0-nvme-ssd-2tb-mz-v8p2t0b-am/ https://www.westerndigital.com/products/internal-drives/wd-black-sn850-nvme-ssd#WDS200T1X0E https://www.dell.com/en-us/work/shop/dell-laptops-and-notebooks/precision-5560-workstation/spd/precision-15-5560-laptop/xctop556015us_vp?view=configurations:

    Indeed, this is what's written in the document linked by AL123: DOO fans, which are a Dell proprietary design (patent number: 10,584,717 with further patents pending), improve on traditional fans by increasing the performance of the airflow system. The DOO design increases the size of the fan blades relative to the fan body, improving efficiency. The blades are made of liquid crystal polymer (LCP), which allowed designers to reduce blade thickness and pack in more fan blades to increase air flow per rotation.
  18. Conan11
    Ah, that's helpful. Thanks everyone! Yes, from what I read Alienware x series have very good cooling in terms of amounts of heat it can remove, but they also have reputation of being loud.
  19. Conan11
    Thanks. I've been looking at these pictures, but I'm not sure if they show the exact models? For instance, there are some differences between various photos of various components for the same model. 5570 page https://www.dell.com/en-us/work/shop/workstations-isv-certified/new-precision-5570-workstation/spd/precision-15-5570-laptop/xctop5570usvp?view=configurations mentions DOO. 5570 spec sheet: https://www.delltechnologies.com/asset/en-us/products/workstations/technical-support/precision-5570-spec-sheet.pdf mentions DOO with liquid polymer blades But if DOO consists of two fans placed next to each other, none of the 5570 photos or diagrams I could find shows it. This is a bit... confusing.
  20. Conan11
    I wonder if more air circulation means that the fans run more quietly at similar loads? Or the opposite, the unit can evacuate more heat, but at the expense of noise? I'm more interested in difference between 5560 and 5570, but if I understand correctly all xx70 models get similar cooling upgrade?
