Is this program REAL? #15

Open alainazpe opened 6 years ago

alainazpe commented 6 years ago

Hello,

When I open the program my GPU is correctly detected, so I click on "Mount" button:

gpu

So the partition appears on "My computer", but it isn't getting the memory from the GPU, it is using the system RAM:

So, is in this case the program working incorrectly or, this program is only making a RamDisk?

Thanks.

Hi, I never heard that device. It is possible that your VRAM is shared with system RAM. Does your GPU have dedicated RAM?

alainazpe commented 6 years ago

Is a Sapphire Radeon R9 290 with 4GB of VRAM. Here you have an image of Windows recognising it: image

I tested too, it's fake. Program using normal RAM, not GPU RAM

Is there any kind of solution for this issue? I can use Intel HD Graphics shared memory as ramdisk but I can't use Radeon 8570M's 2GB dedicated memory. It uses system Ram.

Works perfectly fine on Nvidia cards. Now sure why you ppl have issues.

bzn7 commented 5 years ago

Is there anything for me to do to find problem on Radeon's? @prsyahmi

For Nvidia this tool uses CUDA which is not supported on AMD cards. Possible OpenCL support is broken and thus its not working and by default the fall back is to use system RAM, which some here did observe.

On Nvidia cards you can see that GpuRAMDrive does allocate memory using GPU-Zm than you use ATTO to check that the performance is as expected.

AMD card try this https://github.com/brzz/GpuRamDrive/releases

The way the task manager displays is it combines shared memory usage and display it there. Note that it says "Memory" and not RAM.
