    Integrated HD graphics - workaround solution for dedicated video memory

    seekingbuddha

      After extensive search on the internet,   the only  useful thread i found is  in these forums (Is it possible to increase the amount of dedicated video ram? ).  My system (Thinkpad T410 laptop - see attached image below for details)  has  integrated  Intel HD graphics.   I took image below by going to Intel Control Center, to show the details of the GPU/system.  "Process Manager" reports only 64MB of  dedicated memory to GPU  and i understand that system will use the shared memory as needed.  But, streaming video is stutters,  and I want to  allocate more into the dedicated GPU memory (since i am usually using only half my RAM).   I tried creating the Registry entry  as pointed in the above URL,  and  assigned 256 (decimal)  to the entry i created.  Reboot system -> still has only 64MB  dedicated to GPU.  Is there any work around to increase the GPU dedicated memory, so that system does not have to dynamically  intervene  into  video  operations ?  (I have the latest drivers installed with a SSD in system;  BIOS has no options to change VRAM).

          By the way,  i also came across another  internet  thread (How To Get More V Ram Memory From HD Graphics On A T410? )  that  has a posting / URL to download,  where  i can find & install a "modified driver".  I have no further info but this modified driver would  increase the dedicated vram  on this laptop.  I am  uncomfortable  with that idea,  as we have no clue as to what goes into a  device driver that comes from a non-authority  source.   If  someone  has posted a modded  driver  in  Intel  forums,  i would be more comfortable  with the idea i guess.  Comments on this welcome. Thanks.

            Hello seekingbuddha,

            If you tried the suggestion posted by Bryce@Intel and it did not work then from our end there is no much we can do. In some Laptops in the BIOS there is an option to increase the dedicated video ram called DVMT; you can see the following thread:
            https://communities.intel.com/thread/20552

            Basically this depends on your motherboard BIOS and the way DVMT option appear. If this is not there you can contact your Laptop manufacturer to check if there is a BIOS update that can support this configuration.

            I’m sorry from our end this is all the support we can provide.

            Best regards,


            Ivan.

              Hi   Intel  support  Rep,

               

              Thanks for your answer.  I will contact  Lenovo but there is not much hope since their support is nowhere  near  Intel  support in these community forums.   So, i am on my own to try and find a proper  driver  on intel website,  since  Lenovo has not updated  video drivers  in many years (my T410 is an old model).   Now,  in order to find the right driver from Intel website,  for my  "Integrated  Intel  HD  graphics GPU",  i  need to first  find out what exactly  is the version of  HD GRaphics  GPU  that is  Integrated into my  motherboard.  How  would i find out the exact model number of my  Intel  HD graphics ?   Note  that i have posted  the relevant  output from Intel Management Engine/Software  in the  images  i posted with original  post. 

               

              I am pursuing  this to the end,  even though hope is low  because  I can not stand the  stuttering  and poor  performance  in simple  video  streaming  from  HULU.com or netflix.   I am not even playing games on this,  which  are more demanding  than  video streaming.   So,  i can not understand  how to fix this issue.  CPU  is spiking  upto  80% during video playback  even  though i have a Intel i7  at 2.7Ghz - the only  explanation  i can think of  is that  CPU  is  sharing the load  of the  GPU  in order  deal with the shortage  of  VRAM  etc......

              Thanks for your support.

                Try to see if you can install this driver:
                https://downloadcenter.intel.com/download/22521/Intel-Graphics-Media-Accelerator-Driver-Windows-7-64-Windows-Vista-64-exe-?product=43560
                 
                Note: Based on you processor model, this driver is available for Windows®7 only, there is not Windows®10 support for this version.

                  Thanks  Intel.   Installing the above mentioned driver (which my manufacturer/Lenovo  did not supply)  has helped slightly.  I am noticing that  GPU is using more of system memory (which i had plenty of  while video streaming, but previous driver was not using as much as this new is using).  So,  the video playback has improved definitely, and i am also noticing that more of  "Shared memory  usage" now.   But,  the video  stuttering/freezing   has not stopped completely.  That is a shame, when there is 1.6GB of  shared memory allocated to GPU,  but it is only taking up about 250 MB to 300MB  for a video playback (in addition to the 64MB that is dedicated to GPU).   It would be nice if  Intel takes notice of this fact, and  changes the video driver  in future, to more effectively  use  shared memory  because  video  streaming has become an integral part of  a large population in  USA.  Thanks much for the pointers.  Lenovo  support sucks and Intel support is more active in replying in forums.

                    I’m glad that this driver helped you at least a little bit, with your system; most likely this is a limitation from Lenovo.

                    With most recent computer technology there is more dedicated video memory available, but this is the previous graphics version that it was launch at the beginning of 2010 so at his point the support for this graphics is limited from our side especially because of OEMs limitations.
