Hello! I'm new here and hope all goes well, as what I've been trying to look up, there was no answers or seen any scenarios of the gpu model of the like that I have.
System Specs (Custom Built Desktop):
- PSU: Corsair CX750M (750W, 80 Bronze)
- Motherboard: Asus Maximus VII Hero
- BIOS Version: 3201
- OS: Linux Mint 19.1 Tessa "Cinnamon" 64-bit
- CPU: Intel Core i5-4590 (Up to 3.70GHz)
- RAM: G.Skillz DDR3-1866 2 x 8GB (16GB)
- GPU: AMD Radeon R7 250 (Dell OEM, 2048MB of DDR3)
- Radeon Software for Linux (PRO, version 18.50-725072)
- Display Device: Insignia NS-24E730A12 (1080p @ 60Hz, DVI to HDMI)
For a quick rundown of what I did beforehand:
Although the AMDGPU-Driver or AMDGPU-PRO-Driver page on Ubuntu's website doesn't mention anything about my GPU model being supported, AMD's website does; so I've went ahead and edited /etc/os-release to Ubuntu (and changed it back after restarting), extracted the tar.xz file, ran ./amdgpu-pro-installation, then restarted.
All was working well as a video I was testing in 1440p 60fps was running really smooth, but when I started up a game of mine followed by connecting to a server, the game reporting Out of memory or address space. Texture quality setting may be too high. , other times it would immediately close itself without any warning.
After executing sudo lspci -v -s 01:00.0, I've gotten this:
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Oland XT [Radeon HD 8670 / R7 250/350] (prog-if 00 [VGA controller])
Subsystem: Dell Radeon R7 250
Flags: bus master, fast devsel, latency 0, IRQ 29
Memory at e0000000 (64-bit, prefetchable) [size=256M]
Memory at f7e00000 (64-bit, non-prefetchable) [size=256K]
I/O ports at e000 [size=256] Expansion ROM at 000c0000 [disabled] [size=128K]
Capabilities: <access denied>
Kernel driver in use: amdgpu
Kernel modules: radeon, amdgpu
The output showing that the video memory for my video card reported to have 256MB, despite the fact that it has 2GB on-board it...
Is there anyway I can fix this, or get it to recognize the full 2048MB video memory?
