I own a laptop without a dedicated GPU. I’ve managed to run AAA titles with high graphics settings, and I see varying VRAM values displayed. This is puzzling for me since I’m not very technical. I’m curious about the exact VRAM capacity I have and whether there’s a way to adjust it via BIOS or Windows. If my system has limited memory, can I change settings to make it appear as if I have more VRAM? I also want to know how to trick the system into thinking I have more RAM than what’s physically available. Previously, I had 8GB of RAM and read about boosting performance by increasing RAM, especially since my CPU is AMD and benefits from dual-channel memory. I upgraded to a 16GB stick (total 24GB) at 3200 MHz, which improved performance. However, I encountered issues with VRAM values in the display properties—first it showed 128MB, then it changed to 512MB. I checked BIOS and used DxDiag, but I’m unsure where the VRAM numbers come from. I also tested various games like Assassin’s Creed Odyssey, Black Ops Cold War, Code, WW2 RDR2, and Watch Dogs 2.
Your AMD Ryzen 7 4700U uses the Radeon RX Vega 7 graphics card. It seems these APUs typically have restricted GPU memory since they share system RAM, though your setup shows 512MB of dedicated VRAM. For more details, check the provided links: the first one covers benchmarks for this model, and the others discuss its architecture and performance.
You're asking if you can boost the VRAM by using more of your system's memory. With 24GB available, it might seem possible, but it depends on whether the RAM is shared with other components like the CPU or GPU. The motherboard and chipset also play a role in setting limits. You’d need to check your system’s specifications to confirm compatibility.
The video chipset has a limited VRAM capacity, meaning you can't just boost it by adding more RAM unless you upgrade your GPU. AMD's APU processors are built this way, so the GPU often uses some or all of the system memory to compensate for the smaller dedicated VRAM on the chipset.
I understand your point, but AMD's documentation contradicts this. Still, if the data is incorrect, it's frustrating that a major chip and processor company would spread misleading information to consumers. I don’t have an APU myself, but I’d expect transparency from such a large manufacturer.
The documentation doesn't mention any special VRAM allocation. The 512MB figure refers to general system memory reserved for the GPU, not a dedicated VRAM space.
