increase vram without bios

enter the bios, set vram size for the integrated graphics to 2048MB or 2GB, this is the maximum for integrated Vega graphics on AMD CPU's like the Ryzen 5 2500u. Tho some manufacturers lock this ability for normal users, for "safety reasons", basically they don't want unknowing customers to alter their products setup, because it can damage the machine. like explained here: https://h30434.www3.hp.com/t5/Noteb... But Vram capacity for vega might be unlocked :) here is an example video: https://www.youtube.com/watch?v=506... btw there shouldn't be much of a difference, because if the vega grahpics(iGPU) runs out of Vram (integrated GPU vram is actually system RAM), it will tap into the system RAM anyways. the only benefit you could see, would be games or other apps, checking your hardware setup to see if there is enough dedicated Vram available. So the app will not check for the not yet allocated system RAM, which the onboard Vega GPU can also use as Vram. Hope this makes sense, if it doesn't feel free to ask away. notes: GPU=Graphics processing Unit on-board graphics=same as GPU iGPU=integrated GPU ^ (means the same for you as the 2 above) VRAM=Memory dedicated to the GPU RAM=system memory YOUR GPU=AMD RX Vega 8 (Ryzen iGPU) YOUR CPU=AMD Ryzen 5 2500U default iGPU(vega 8 grpahics) vram=128MB or 256MB max iGPU vram=2048MB or 2GB for short i5-6600K[delid]@4.7GHz/4.4GHz cache/@1.395v LLC=6 | 2x4GB Crucial-DDR4-2400CL17@14-15-15-28 1T 3000MHz@1.4v | MSI Armor RX 570 4GB@1410Mhz core@1.2v/1920MHz message edited by hidde663

so i cant change it?

You can attempt to "fool" windows, but you'll have to try something like this: https://www.youtube.com/watch?v=85f... this doesnt actually change the VRAM size, but you can fool games into starting with "too little to run" amounts of Vram. note that 1GB= 2^30 = 1073741824 bytes, not 1000000000 2 GB would be 2^31= 2147483648 bytes, not 2000000000 attempt this at your own risk, and make a windows restore point if possible as i do not know what will happen if you start writing data to a memory location which doesn't exist. Please note that in the video hes working with a HD 5450 i believe, and you should be looking for one of those long {1726916HF-861531-bla-bla} folders" where the 4th entry says "AMD Vega 8" Graphics instead as shown in the video@1:52 and for checking if it worked, use something like GPU-Z, found here: https://www.techpowerup.com/downloa... i5-6600K[delid]@4.7GHz/4.4GHz cache/@1.395v LLC=6 | 2x4GB Crucial-DDR4-2400CL17@14-15-15-28 1T 3000MHz@1.4v | MSI Armor RX 570 4GB@1410Mhz core@1.2v/1920MHz message edited by hidde663

Your graphics chip is integrated into the CPU therefore the "vram" is not dedicated, it's shared. In other words, the graphics memory is taken from system memory. There may or may not be a base setting in the BIOS (256MB, 512MB, 1GB, etc). Anything beyond the base setting is taken dynamically on an as-needed basis. If better gaming is what you're after, your only choices are to lower the in-game settings to improve FPS, or get a gaming laptop with better specs.

I just had a feeling he was getting running out of VRAM, because the default setting is 256MB for the vega 8 iGPU. why else would you need more than 256 MB. my previous answers just explain how to trick certain applications into bypassing a hard-coded blockage, but not without risk. i think its better not to explain the difference between dedicated and shared and what not types for VRAM/RAM. of niet dan :) i5-6600K[delid]@4.7GHz/4.4GHz cache/@1.395v LLC=6 | 2x4GB Crucial-DDR4-2400CL17@14-15-15-28 1T 3000MHz@1.4v | MSI Armor RX 570 4GB@1410Mhz core@1.2v/1920MHz message edited by hidde663
