PC Building

[frangx808]

Hi, how are you? I have a pc with this specs:

- CPU Ryzen 5 5600GT
- Motherboard Gigabyte A520M K V2 (Rev 1.1)
- Two modules RAM 8GB to 3200mhz = 16 GB RAM

The problem I have with this processor is this: only i can put 2gb of VRAM and I can't put 4gb of VRAM, as I saw in other videos (with exactly the same CPU). I already tried updating the BIOS but the same problem continues.

Could it be a CPU issue?
Could it be that my motherboard also has a limitation?
Or maybe it's something else?

I would really appreciate your help.

PS: Later I plan to install a dedicated graphics card to play at 1440p. What would be the best graphics card for this cpu? Considering that I am aware of the bottleneck.

The integrated IGP of the 5600GT processor uses system memory to assign for VRAM. Therefore the amount it can allocate to use depends on the total amount of system memory present. It also depends on the motherboard support.

First make sure you are on the latest non-beta BIOS release. Then enter the BIOS under Advanced Mode (not Easy Mode) and go to Settings, IO Ports. Select UMA Mode and change from Auto to UMA Specified, and set the UMA Frame Buffer Size to the desired size.

I would urge you to benchmark test between 2GB and 4GB of VRAM however, as you will likely notice very little if any performance improvement in gaming. The IGP is simply not powerful enough to need or benefit from more than 2GB of VRAM. In fact, there is only a marginal improvement going from the default 512MB to 2GB. (<10% or around 1FPS on average in testing)

As for choosing a future GPU, keep in mind that the 5600GT processor only supports PCIe gen 3.0 and only 8x lanes for the graphics card.
