vram upgrade

[Saerp]

hi i just wanna ask how to increase vram i have ati radeon hd 4650 512mb and i wanna 1024 or something like that and how to do it in windows , and if it increase performance

i increased the vram in my intel hd 4400 by editing the registry

Yeah that is a Intel HD. And it uses your normal RAM so it will be SLOW.

I believe vram is exaclty that, like some old VGA.
I think VRAM is virtual ram, an virtual memory, or logic memory, is a part of the RAM, dedicated to store VGA things, like an "extra" memory for the VGA.
For example, an 8400GS have up to 512mb RAM, but it could store 1,5gb of data, using those shared 1gb.
The OP could search about it, since is logic, its possible.

VRAM is physically built into your GPU. While I believe a GPU can use your system RAM, it wouldn't help much with a system that old.

TurboCache technology is a method of allowing video cards more available framebuffer memory by using both onboard video memory and main system memory. Main memory is accessed using the high-bandwidth PCI-Express bus."
TurboCache is the name for the nvidia version, i believe intel and amd has different names for this, but intel for sure does it.

No like MossyRathalos said; Vram is actuall RAM build in to the GPU. Intel HD uses the normal system RAM for storage but that is very slow compared to Vram.

TurboCache is trash I don't think modern GPUs even use it any more.

I dont think so, look at those pictures, first one, vga without any dedicated memory (or driver support)), 100% of "VRAM" is shared with main system memory.

Now, newer version, with dedicated memory and more memory shared.

Another picture, showing usable memory, less than total, because it is sharing with the VGA.

If you have an hd graphics and an pci-e card you can test it yourself, take your VGA out, and see your usable memory decreasing..

Sorry about virtual ram, i miss confused with virtual memory, my bad, but my point still valid.

Integrated GPUs don't have their own dedicated VRAM. They utilize system RAM (shared RAM). This is why faster system RAM for APUs means better gaming performance. You can see for yourself the differences in performance on AMD's APUs on this link from Tomshardware (it's a few years old, but it'll prove my point): http://www.tomshardware.com/reviews/memory-bandwidth-scaling-trinity,3419.html

You cannot add VRAM to an integrated or dedicated GPU. It is possible for a GPU to utilize system RAM, but system RAM for a GPU is a lot slower than it's own dedicated VRAM. Shared system RAM is not the same as VRAM.

The first two screen shots, they show us how much shared RAM the system can use. The integrated GPUs are using the system RAM and not VRAM. Integrated GPUs do not have VRAM.

The third screen shot could be a combination of various hardware needs for the system to hold available system RAM so things can function properly. That APU processor is still utilizing system RAM.

You cannot add VRAM to a system. VRAM is built in directly to a dedicated GPU. If you need an image, you can check out the circuit board that was analyzed here on techpowerup ( https://www.techpowerup.com/reviews/MSI/GTX_1080_Ti_Lightning_Z/5.html ) for the 1080Ti Lightning. You'll see the orange highlighted squares around the GPU chip - those are the physical memory (VRAM) chips.

What i trying to say, it is possible to make integrated GPU use more System ram..
Im miss confused vram with virtual memory, thats it..
I re-read again and see where i made a mistake, sorry guys..

Virtual Memory is a part of computer's Hard Disk Space which sometimes works as a System RAM when needed. it has nothing to do with Graphics card or GPU. No connection.

I already sorry.. what else do you want dude?
They both works to achieve the same goals, more memory.
