live chat session is a AI chat only...  it is not a real technical support .it is useless....

I have joined Pro Support 5 years plan already... I just want to find a solution online which could be faster only....

But other people could be wondering the same thing. Everyone has to message support?

I used Prevision 3650 with AMD W5500 display card, I also want to know why BIOS not support resizable bar?

Dell have released resizable bar support firmware update for GPU in 2021..... they have addded BIOS support on alienware series as well.... I believe some precision workstation BIOS / chipset is NOT able to add resizeable bar support probably.... as it have been over 1 year already....

NVIDIA GeForce RTX 3080 Firmware Update Utilityv1.0.0.2, A00 Release date
28 May 2021 <--------------
- Supports Resizable BAR feature to improve the gaming performance. <--------------------

Thanks for DELL-Cares Moderator check for me and confirmed there are no support on 3640.......

From what I had check online from google and community, seems DELL only provide resizable bar support on Alienware series only.... Y_Y

update :   I have another 3650 system, after updated BIOS , it have resizable bar support on / off option now.

so DELL not only support resizable bar in alienware.  

Please make a request to add support for resizable bar for the T3640 too.
