I'm not a computer engineer or something and I'm so curious why my gpu has 4gb but when I open my directx diagnostic tool (DXDIAG) , On the display panel, it shows that my gpu has 8129MB of Approx. Total memory. How did that happen?
 
Solution
The more detailed answer is how DXDiag registers memory.
Technically speaking you (and I) have 4GB of VRAM modules on our cards, realistically, this means you have 4 usable GB of memory.
DXDiag however, also includes pagefile into the count. You can process up to (in this case) 8GB of memory for the card, but only 4GB (the amount on the card) is actually fast enough to be considered usable. Hence if you ever go over Vram limits, it stutters because the system is waiting on the much slower memory outside of the card.


It's an Asus Strix GTX 960 OC II 4gbddr5. I'm just curious that's all haha thank you
