Increase vRAM in Dell 5575 with AMD Vega 8 graphics

Question

I have Dell Inspiron 5575 laptop with Ryzen 5 2500U and AMD Vega 8 graphics. The system shows that available vRAM is only 256MB. Is there any way to increase the vRAM? Any suggestion will be highly helpful

If you don't see any options in the BIOS to adjust that, then there's no way to change it.  I haven't seen options to change the VRAM allocation for a very long time, back when the options ranged from 1MB to 64MB.  However, although you may only have 256MB of VRAM dedicated to the GPU, it's likely that the GPU would be allowed to use additional system RAM as VRAM when the system doesn't need it. This is normally indicated in Windows as 'Maximum shared memory' or something like that.  If the system DOES need all available RAM, then the GPU wouldn't be able to use it, but in that situation the system will likely perform better overall by keeping that RAM allocated to the system rather than the GPU anyway.

There is no way to increase VRAM. Dell should upgrade the BIOS to allow us to change VRAM memory it's the only way or change the VRAM from 256Mb to 512Mb. From my point of view DELL is not interested in doing this in order to sell high end laptops, but it's downgrading the Ryzen 5 2500U power and not taking care of costumers. HP allowed their X360 users to change VRAM. DELL is not truky interested in caring their costumers.

Again and again and again.December 05, 2019, Dell releases the following bios update: VersionVersion 1.3.3, 1.3.3CategoryBIOSRelease date05 Dec 2019 Fixes & Enhancements- Updated the Video BIOS (VBIOS) to support the new Video RAM (VRAM).--------------------But after my update, no correction, the dedicated RAM is still 256MB. Dell's support wrote to me to say that it is impossible to correct the small amount of dedicated RAM. Stupid answer, because Acer and HP have made a bios update which corrects the same error on the Acer Swift 3 and Hp Envy 360 15z models. I also noticed that their updates allowed to go from version AGESA (AMD) 1.0.0.2 to 1.1.0.5 (which corrects the problem of RAM). On the Dell inspirion 5575, the bios version 1.3.3 only entitles you to AGESA 1.0.0.3.So Dell, other companies have done the impossible .... So do the impossible for us please.Thank you (i wait the bios update )

null132,   Apologies that you are not able to increase the vram on the system.   Dell-Jesse L

Yes this was very upsetting. All the other laptops with this APU have had BIOS updates that let you increase the VRAM up to 1GB but not Dell? I was actually excited for the last upgrade but it didn't change anything performance wise. I'm very dissatisfied with this laptop

I already told all my friends NOT to buy dell.I lost about 48000 in my currency.About 680$ usd.I will never ever buy dell.Nor will I let my family members buy one.

Thanks for the reply. I know it's not your fault but this is really upsetting, since the hardware itself could absolutely do more, and other OEMs have eventually patched out these restrictions. I guess it's up to the community to figure out how to reverse engineer the BIOS, and I will not be buying from Dell again
