Razer Blade Pro 2016 / 2017 UHD

  1. I want my Intel GPU to be enabled in my laptop, so I can extend battery life and do cool things!

  2. I don't want my Intel GPU to be enabled because I don't understand use cases or afraid for G-Sync

  3. I don't want my Intel GPU to be enabled for other reason

  1. Hey there,

    Recently I made a post that my new Razer Blade Pro 2017 UHD doesn't have Intel 630 GPU enabled and my post was deleted with a reason that it's not a support forum (which is pretty interesting taking into account the fact that support team became silent last two days).

    I'm wondering that such a powerful laptop doesn't have a BIOS setting to invoke iGPU, so I want to identify whether other Blade Pro 2016 / 2017 users actually need such a feature in order to make an official request to Razer Company.

    This feature will allow you:

    - To reduce battery usage in times comparing with Nvidia GPU usage in simple tasks like video watching, internet surfing etc. You may assume that with switching on iGPU you will get like 5-8 hours of work with economy plan used (depends on your battery current state). G-Sync for such a case shall be disabled for OS but it will automatically be switched on each time you will start your game thanks to Nvidia Control Panel;

    - Do a GPGPU programming or executing GPGPU programs, which is essential for people who is involved in Computer Science or IT work. Without this you simply can't debug your or 3rd-party code;

    - Unlock iGPU for Physx or for other applications/processes you may invoke using Nvidia Contro Panel.

    If anybody wants this feature delivered with new BIOS and iGPU driver, post your vote here. I hope that Razer moders will not delete this thread since this is a kind of vote and request.

    Is it really that hard to understand ?

    For any modern switchable graphics to work, the iGPU needs to be attached to the internal display. Times when both GPUs had a physical connection and were switched by multiplexers (hardware key) are long gone.

    To adaptively change the display refresh rate (G-SYNC) the GPU and it's display controller needs to talk directly to the display. This can't be done when the video signal is passed trough the iGPU, there is no interface or protocol for that. So, for G-SYNC the 1080 is directly attached to the internal display. That's why the iGPU is disabled on that model, as it is useless. What benefit would be there to enable it ? It can't output the video signal to anywhere (or maybe through TB3 on an external screen), but especially not on the internal display.

    Just read this article: https://www.notebookcheck.net/Nvidia-Optimus-Review.25467.0.html

    What you want is a revision of the UDH model without G-SYNC (like the FHD version) that offers Optimus instead.

    I think it’s better to look to other laptops that has that option like Clevo, if you need the features to switch both iGPU and dGPU in a Laptop that has dGPU more powerful than 1060 (hybrid Optimus and gsync)
  4. You refer to old tech description that is not related to modern iGPU implemented within CPU SoC. I told you once already, that this implementation you refer to has nothing in common with modern implementations (there is no, e.g., Intel GMA 915 as a part of north bridge chipset which is not directly multiplexed with discrete GPU as it was done in the past).

    "Normal companies" such as ASUS / Clevo imlemented their hardware (or the thing you call "Optimus" in 2017) with a switch in BIOS


    I guess you will say on this something like "These companies put a direct connection between eDP and iGPU!" which will make me laugh once again.

    Also, I didn't ask you to comment and to missrefer,

    I asked Blade Pro 2016 / 2017 UHD owners to vote and support in order to make a request in Razer copmany to do a BIOS firmware because

    I believe that company who sell laptops for 4K USD shall not be so lame and should provide an opportunity for its customers to specify their own use case and way to use their hardware.

    Anyway, if you have an interest to support my proposal or you want to accept a challenge of this feature implementation (in order to prove that you missrefer), please vote also :big_grin_:

    Did you actually read the reddit post you linked to ? Here is a quote that says everything:

    What you refer to is outdated. I wasn't aware that Clevo still does it, but see it as an exception. Do you really think Razer would do all the trouble by implementing a Mux for the iGPU / dGPU and then just don't give you the option to actually use it (by BIOS switch f.e.) ?

    Edit: Or here is another one in case you think I posted that there:

  6. Check ROG laptops which have both G-Sync and your lovely Optimus. This is done or by chipset, or by mux in case chipset is a custom or old one. That's it. Any iGPU is "directly connected" in terms of physical lines. It's a business of firmware / BIOS to enable iGPU or not. And also I'm tired to argue with you. You may ask Razer support team if you don't believe. Razer support team also told me that it's possible to invoke it (last message I received from them). But I believe that they have to implement this feature in a firmware they will deliver.

    One more video for people who believe in magic like "direct connection" :eek_::

    Also, in case of no support from Razer company, I will put my paid request here


    And do it by myself. The problem is that I put 4K USD in this creepy "iGPU not connected directly to an eDP panel" laptop already and there is no way back, so I have to clarify this somehow by myself.

    Unlocking the Bios will do nothing to activate the iGPU, only laptops with a mux switch would allow for this, i.e. clevo. Unlocking the bios on the RBP shouldn't be hard, since I believe it is not signed, like on the RB 14.
