does vram count twards os max?

[dudester101]

OK so suppose i had a x64 OS that maxed out at 8GB and i had 6GB of ram then got a graphics card with 4GB of vram would it work at full capacity, be bottle-necked or not work at all.

And furthermore what if I had the same kind of scenario but with the MOTHERBOARD max set to 8GB and the OS was higher.

vram is for gpu only.

A 64-bit OS should not have an 8 GB limit. A motherboard may list 8 GB as the maximum supported memory configuration, but that's not the same thing.

In the past, the addressable memory on a GPU had to be mapped inside the usable address space in your OS, but using a 64-bit OS has long since eliminated that as a common issue.

The motherboard's memory addressing limitations and the OS's memory addressing limitations are two different things. The memory on your GPU is not going to count against the total installable memory your motherboard can address, but it will count against what your 64-bit OS can address, however a 64-bit OS can handle significantly more than you have to be concerned with. Ultimately, you also have to consider the CPU, the device actually doing the physical addressing, and I think you will find that most modern processors can handle somewhere on the order of 8 terabytes of address space, so you should be fine for the near future. 🙂

ok so i wouldn't need to worry about getting a better gpu for this PC even if it was a really old 32x system with a 4GB limit or whatever i don't need to worry becuase it doesent work that way

If you are running a 32-bit OS you may run into problems. 32-bit Windows, even with PAE (Physical Address Extensions), limits it's physical address space to 4 GB. Your mileage will vary with other operating systems.

thank you for clearing that up i was really confused about that
