    Awesome!
     
  2. I got egzakly the same problems as you with the core and also do the trick with bending but it wouldn't fix the issue. Next I pull out tray with GPU from the core and attach little magnet on the rail to be able to turn this on without the chasis and it's worked for 2 days... So I was really angry and call Razer and they send me this:

    A) Reset the graphics card, then secure the cable connections within the Core.


    B) Restore BIOS settings to default

    1. Power on your laptop via AC adapter and immediately spam the F1 or Del key until the BIOS menu loads.

    2. Select ‘Save & Exit’, then select ‘Restore Defaults’. When prompted, select ‘Yes’.

    3. Select ‘Save Changes & Exit’. When prompted, select ‘Yes’.


    C) Perform system recovery, as the issue may have originated from Windows.

    1. Please backup your files as it will be erased in the process.

    2. Power on your laptop via power adapter and immediately spam the F9 key until the recovery menu loads.

    3. Select ‘START RECOVERY’ and follow the on-screen instructions. The process could take around 20 minutes to complete. You will have to reconfigure your laptop after the process is completed.


    D) Connect your laptop to the internet using an Ethernet cable or a 5GHz band wireless network. Please do not connect your laptop to the internet using a 2.4GHz band wireless network.

    And... it worked! For me the issue was with 2.4Ghz wifi, I bought new dual band router and it worked 4 days now without any issue. Hope that would help somebody.
     
  3. adrianplona funny you mention that I switched my wireless card to 5ghz in this whole troubleshooting process Friday when I decided to go ahead and remove the paper clip and press the rail slightly inward on the end to ensure good contact with the magnet. Rand across this thread and noted how many people had their issues with BSOD, etc. fixed by doing that.

    If you go into device manager and right click your "killer wireless" card you can go under band / frequency settings and set to "5ghz" only to alleviate that issue. Even with a new router depending it could swap back to 2.4ghz and cause the problem unless you have 2.4ghz completely disabled on the router. Interesting that something like 2.4ghz would have such an effect on the Core.
     
  4. Yeah, everybody thinks that was the problem with magnetic connection but in the end it was 2.4Ghz wifi. A wifi and a core. That's just don't seem to be correlated. :stuck_out_tongue_winking_eye: but it works now and that's most important thing. Cheers.
     
  5. Yeah I think my magnetic connection was fine with the paper clip test making the connection, I think I did everything at once including drivers, tweaked tray rail, and also swapped wireless card to only work on 5ghz in windows (thanks for some insiders). It's working perfect now and exactly like you said it's the friggen wireless that's the issue. Is it only a select number of users having issues with 2.4ghz wireless with the Core? Figured we would hear more about it on the forums or in the documentation / install steps.

    http://www.razersupport.com/gaming-systems/razer-core/

    Notice first FAQ question / answer is "for best performance ensure wireless and core are on 5ghz". Interesting wonder why, and why the issues related to 2.4ghz.
     
  6. Congrats! That's exactly what I did...Still had to RMA mine though...But I get the new one in today, so we will see how things go.

    Can you tell me what rail you are talking about bending, exactly? A pic (or explaining with one of the pics you posted previously) would help.

    I think I'm having this same issue occasionally, and to get the core to work I have to power cycle it (not unplug the TB3, but actually unplug the AC).

     
  8. Don't bend anything, it's not the problem.

    Do exactly like it write in those steps and it should help:

    A) Reset the graphics card, then secure the cable connections within the Core.


    B) Restore BIOS settings to default

    1. Power on your laptop via AC adapter and immediately spam the F1 or Del key until the BIOS menu loads.

    2. Select ‘Save & Exit’, then select ‘Restore Defaults’. When prompted, select ‘Yes’.

    3. Select ‘Save Changes & Exit’. When prompted, select ‘Yes’.


    C) Perform system recovery, as the issue may have originated from Windows.

    1. Please backup your files as it will be erased in the process.

    2. Power on your laptop via power adapter and immediately spam the F9 key until the recovery menu loads.

    3. Select ‘START RECOVERY’ and follow the on-screen instructions. The process could take around 20 minutes to complete. You will have to reconfigure your laptop after the process is completed.


    D) Connect your laptop to the internet using an Ethernet cable or a 5GHz band wireless network. Please do not connect your laptop to the internet using a 2.4GHz band wireless network.

    Especially important is point D!
     
  9. Did anyone try to connect the core to Ethernet and do the update or connect there laptop to Ethernet and do the update? Was wondering how that worked out for them?
     
  10. Douglas sorry it took me a bit to get back on here and reply. I just want to note that since doing this I haven't had a single disconnect, no reboots, no blue screens, and so far I've been able to play Edge of Nowhere on the Rift 2-3 hours straight no lockups.

    That little metal tab that the plastic rail piece is screwed to needs slightly bent / tweak inward toward the tray / psu. It doesn't take much really just put a little pressure and get that tab leaning more inward.

    [​IMG]

    That little piece with the two screws next to each other holding it on the enclosure is the magnet that the rail touch's to establish that it's "installed" in the enclosure itself. I also put some pressure on the piece and pushed it toward the rail track you see under the mesh grill.

    Like I said above so far I've had no issues, I did follow the crazy suggestions of setting my wifi card to 5ghz only which could have helped also. But the main thing was the issue of not getting the power clicks and I believe a gap between those / flaky connection was causing more of the issue since the rail metal and magnet were not touching or barely touching giving it a loose connection. Not sure what all the magnetic sensor on the tray itself is looking for, possibly it needs a certain amount of magnetic strength / presence. I know those switches exist in many other things and they require a certain amount of magnetism to trigger I assume the same is true here. See if that helps, sure beats waiting 2-3 weeks without a Core if the Core itself is fine. Always have a year to send it for a replacement after that tweak the design / manufacturing.

    Thanks so much for that. Just opened it and pressed the rail in. Hopefully I'll see more stability.
     
  12. No problem. This past weekend I was able to let my Blade + Core sit running 24/7 no lock-ups, disconnect, or crashes. Reboots worked without any issues, shutdown and restart came up just like it should. No instances of chroma lighting going out either.

    I left Overwatch highlight looping Friday night 12 hours no issues still looping Saturday morning, Saturday night left DOOM sitting in Single Player watching a heavy scene run came back 15 hours later Sunday after lunch still running, grabbed mouse and started shooting and moving. So hopefully something as ridiculous as that sensor crap is the only issue hardware wise.

    Are you still getting the loading screen crashes in Doom, though? I wouldn't expect that to go away.

    I wonder if Razer can fix this manufacturing defect (seems that's what it indeed is) with a firmware update that governs the power response to the magnet trigger.

     
  14. I've heard some people mention putting a magnet on the rail (small little one) that negates any need or worry about that connection since the magnet is on the rail (also allows it to run even outside the enclosure to confirm that alleviates the sensor / magnet issue).

    I haven't had any crashes in DOOM at all or hangs, possibly drivers? I'm currently running the latest Intel Beta drivers here https://downloadcenter.intel.com/do...ows-10-and-Windows-7-8-1-15-40-?product=88345 and the 368.69 Nvidia drivers here http://www.nvidia.com/download/driverResults.aspx/104726/en-us . I did run through and use DDU cleaner here http://www.guru3d.com/files-details/display-driver-uninstaller-download.html to completely clean / remove Nvidia drivers first, reboot, clean / remove Intel drivers, reboot, then fresh Intel drivers, reboot, then fresh Nvidia drivers which installs the internal and Core at the same time, reboot. That seems to take care of any crashes, BSOD's, hangs related to drivers.

    Nvidia just released an updated drivers to address performance clock boost issues on 1070 and 1080 for VR games (Oculus and Vive SDK based). They aren't up on the site yet should be available sometime today. Give the driver clean / update regimen a go and see if that helps :).
     
  15. I don't think that the problem is in the rail, because I attached little magnet (strong one) to be able to turn on Core outside the chassis and it still BSOD/restart me. The problem is in Windows itself and 2.4Ghz wifi. After reinstalling Windows and connect only to 5Ghz wifi or Ethernet it worked. I do a little test and change the wifi for 2.4Ghz for a little while and it crashed for about 2 minutes. Set back to 5Ghz and it's working like Swiss watch.

    On an unrelated note, how is the fan noise for you guys on the RBS? I can go all day when I'm hooked up to the Core, but from the first few minutes in, the fan will kick in and stay loud for the entirety of play. Is this pretty normal?
     
  17. Well part of the problem adrianplona is 2.4ghz wifi and part of the problem magnetic sensor. Wifi problem can cause disconnects, BSOD's, etc. which switching to 5ghz only resolves. Now the issue of the Core rebooting it self randomly (power cycle, lights come back on, GPU fan stops and starts boot up spin, etc.) comes from the magnetic sensor not being close enough in contact with the tray rail. A good way to test that theory is plug power and thunerbolt into the Core with laptop off. Open the handle and pull tray out listen for the power click off and power click on when sliding in. When slid in all the way and handle locked push tray and let it move back/forth while handle closed. Listen if you hear power click on/off/on etc. Or if click is inconsistent on locking tray handle in full seat of tray it's the magnetic sensor. This on/off/on click can correspond to random Core power cycle reboots in Windows (heck just sitting at the desktop with nothing on it).

    Between both things I've been 100% stable, 24/7 stress testing GPU no crashes, disconnect, Core reboots, etc.
     
  18. Mine is pretty silent when doing normaln stuff like web browsing, Netflix, Spotify, Photoshop. But when I play some games it get a little loudly. Especially in Doom.

  19. Guys, do you noticed a problem with laggy Windows when operating on external monitor? I record some videos to show you what's the problem is.
