    No worries. If anything it is not as bad an issue as drive slots randomly disappearing or a stability issue. I think the heatsink in your photo and the other review look not quite as uniformly shaped as the one on the service manual site: https://www.dell.com/support/manuals/en-us/precision-17-7770-laptop/precision_7770_sm/removing-the-heat-sink-for-discrete-graphics?guid=guid-de17304b-782a-4ed7-bddd-f2e6f92aaa57&lang=en-us Also, this may sound strange, but I have noticed in the past that there is a marked difference to the initial fan "startup grind/whoosh" depending on the brand of heatsink. Generally I have found that the Sunon models tend to be smoother sounding than the CCI models. Sadly it is somewhat of a lottery in which one you get, and this early in the production phase you cannot even order them as a spare part.

    It really does sound like poor heatsink contact with the CPU surface. If you are willing to repaste it may not hurt to try. You may also want to have them send a replacement cooling system. The pipes on the unit in your photo look like they may have excessive bending marks near the curve. If the sinter inside the pipe was broken from that it effect how well they move heat to the fin stack.

    The Zbook Fury 16 G9 has support for 128GB DDR5 SODIMMS and 4x NVMe drives, but it also only has 80W GPU TDP and I am unsure of the CPU TDP. Also no 3080Ti GPU or a 120hz display.
  4. win32asmguy
    Yeah I had a few general ideas: Conservative LLC settings for current bios; Something related to 128gb memory in use; Poor thermal contact with heatsink; Something related to all m.2 drive slots populated; Something related to windows 11 memory protection or such; Initial thermal throttling because fans need a minute to ramp to max; Poor silicon quality that would be consuming up to 50W more due to higher stock voltage curve or current leak.
  5. win32asmguy
    Wow thanks for checking all of that data. It is a great chip for the NH55! I should delid it as there is thermal throttling.
  6. win32asmguy
    That multicore score makes it seem like it is power limit throttling at 55W or so. Is it with the most recent bios installed?
  7. win32asmguy
    You probably need to contact their support team so they can whitelist the new card device id. Same thing was needed for the 3080 in the 7560 last year.

    The 12900ks is much higher at the start but lower at the top end.. Curve is as follows: 8x 0.914v 18x 0.914v 40x 0.969v 48x 1.159v 52x 1.354v 53x 1.354v 55x 1.354v 47x 1.327v Cache It did not run very well in the NH55 at stock. 135W at 33x P-cores, around 20400 in CBR23. I also tried the locked 12900 non K in the strix z690. It could not read VF curve and the SP rating was crazy high - SP135 or so. Also undervolting had no effect either with the locked chip. The NH-D15S is a pretty tight fit with the strix z690. The Corsair case I have does not help either as there is barely 1.5 inch clearance at the top to unhook those fan clips.

    Finally got some data for my 12900k that correlates why it can maintain higher clocks in the NH55JNNQ. It seems like even though its a poor SP rating, the VF points are lower at 4200mhz and below. I guess these numbers do not indicate how leaky it is, but it is something.
  10. win32asmguy
    It can be very good. Here is a review of a Precision 7760 and desktop 6800 XT via that adapter: https://egpu.io/forums/builds/2021-17-dell-precision-7760-rtx-a4000-11th8ch-rx6800xt-64gbps-m-2-adt-link-r43sg-4-0-win11/ He could have also used a 3080Ti but getting the Quadro dGPU working with a Geforce eGPU has driver conflicts. It would be better to have chosen the laptop 3080 gpu option or just no dedicated gpu at all from Dell's choices.
  11. win32asmguy
    Here is a Timespy benchmark of a 3080 Ti desktop card inside a Razer Core X eGPU connected via TB4 to the Precision 7560: https://www.3dmark.com/3dm/77926408? The other eGPU option is the ADT-Link R43SG 4.0 which can plug in through the bottom cover SSD door to the Gen4 M.2 slot and gives you the full 64Gbps. It is not as convenient as TB4 and you lose a M.2 storage slot but definitely the best option for bandwidth and latency. It will be great when we get a GPU benchmark result from @Aaron44126 so we can see how the internal Precision 7760 3080 Ti compares. It always is a trade off of convenience / power / price.
  12. win32asmguy
    Yep, it will be interesting to see how it compares with the gaming-focused HX laptops already out and the other workstation HX laptops. By chance do you have access to a TB4 device so we can get a topology report for the system via HWiNFO64? I am just curious if its PCIe lanes are via the CPU or PCH, similar to this:
  13. win32asmguy
    https://psref.lenovo.com/Product/ThinkPad/ThinkPad_P16_Gen_1 On the specs page it has a section for the displays. In theory they are all only made by a single vendor so they should have the same characteristics. I do think the 15.6 inch WQHD 240hz OLED in the MSI ge67hx was reported to have PWM in the notebook check review.
  14. win32asmguy
    I am not sure if it helps, but on the Thinkpad P16 it is advertised to have a similar spec OLED touch panel option with "DC Dimming" which usually implies no PWM.
  15. win32asmguy
    It sounds like yours is really close! Mine is still stuck in "Confirmed" so it will probably not arrive until mid-August if I had to guess.
  16. win32asmguy
    I think it would be easier to just get a TB3 eGPU instead, especially now that the mining craze is has died down. They work quite well when the system has no built in dedicated GPU and in a way are even more reliable than using a TB4 dock for connecting many displays.
  17. win32asmguy
    Yep that is a big difference between those 10900k chips. Its a shame that this metric tends to go unnoticed by most of the Clevo DTR resellers, and they force you to buy some kind of throw away processor regardless (unless it was sold by RJTech as a barebone). Maybe some people get lucky and are randomly shipped a great chip, but I otherwise feel its wasteful to pair a DTR with poor silicon, especially since its one of the few machines on the market where you CAN do something about it. I went ahead and ordered a Strix Z690 D4, LGA1700 bracket for my NH-D15S, and a second 120mm fan. I figure that way I can better compare things without having the NH55 specific limitations skewing results. Not sure if microcode injection is going to be possible for raptor lake if modded bioses cannot be flashed on the NH55, but maybe if Jaybee and Prema keep working at it they may find a way. Sadly I doubt I could ever get a modded bios from Prema for mine, as I bought it from Eurocom. It is stupid that they are the only North America reseller for the NH55J... their support also has stopped responding to emails about my open ticket for the wrong keyboard they sent. Not exactly happy with their service.
  18. win32asmguy
    Yep. Did you mention if there was a specific way to test how leaky a chip is? I think I found that certain desktop boards have dedicated voltage regular sensors that more accurately report how much voltage and current is being supplied. So the more leaky chip would draw higher current at the same voltage and load, correct?
  19. win32asmguy
    Got another chip on the way now. This one is a 12900ks, SP91 overall, P-core SP100, e-core SP75. Already delidded with the copper IHS glued down.
  20. win32asmguy
    For the 7760 I ordered last year, it was confirmed on 7/12, went into production on 8/19, shipped 8/25, picked up by Fedex in Chicago 8/30, delivered in Colorado 9/2.
  21. win32asmguy
    Ordered on the morning of 7/7, with the 2 day shipping option. So far it is only in the confirmed status.
  22. win32asmguy
    I have 7/26 ESD and 7/29 EDD, for a 7770 with 12950HX/3080Ti/32GB/FHD. It may ship on time as I have already received a notification from Fedex that a shipping label was created.
  23. win32asmguy
    I have seen bursts of 136W with the 12900k in the NH55. Not bad given Clevo designed it to target 65W LGA CPU's. The undervolting really helps boost performance and lower noise I am very glad its possible now. The BGA chips are ok but I think performance testing in the reviews are kind of useless and potentially misleading because we don't know if the results are because of good/poor silicon or good/poor thermal contact both of which can highly vary even with the exact same model.
  24. win32asmguy
    Yeah those precision tools tend to be better than the generic stuff at hardware stores. How bad is the IHS warped by the stock mounting frame?
  25. win32asmguy
    Maybe a hex nut driver, like these from a iFixit kit?
