Re: I bought a 8GB RX580 GPU and only shows 4gb.

I have exactly the same problem.

The system(Win7x64) sees 8gb but uses a maximum of 4gb.

On win 10 everything is fine.

I need exactly win7.

Installed on different platforms 2011,1151, AM3+(tried different updates).

The result is the same-more than 4gb is not used.

maybe upgrading the RAM capacity will help with the problems, I often advocate Cramming it with RAM

Dear friend screenshots are attached.it's not even about monitoring.I know how the system works on 4GB and 8GB vram.but monitoring does not deceive.on W10 repeat all OK.2019-02-20_135329.jpg
