GPU compression tests are many, there are VRAM performance tests and you know if everything is working correctly, but get a test dedicated solely to component testing such as VRAM and its memory controllers … That's more complicated.
For this reason and to not break your head looking for hours on the Internet today we will know the basic program as it is easy to debug your GPU and VRAM, as if your RAM system.
Video Memory Stress Test: Easy as it is powerful
Used to use software such as Furkmark u OCCT, willing to push the GPU and its VRM and VRAM beyond the limit to show their robustness. However these conditions are not real graphics card while rendering and the problem arises that they cannot separate GPU and VRAM pressure separately.
So, knowing what really fails is a daunting task that without some software being seen by manufacturers alone. Fortunately there are programs such as the Video Memory Stices Test, which we will talk about extensively to test the VRAM of our GPU and its memory managers in charge of handling it.
Test preparation
The first thing we logically need to download is a program, which we can do from here. Once downloaded and unlocked we will use this software, which will look like the one in the image above.
The configuration is simple: we will select the test type (typically under DirectX for the most commonly used API), we will have to select our graphics card in the «Device»And finally the size of the surface.
The larger the size, the VRAM will become more complicated and more difficult to evaluate, and more time-consuming. For first pass we can leave 1024 × 1024 and then pass second and if all goes well, select 2048 or 4096 respectively.
We recommend activating "hold if errors are detected»So that we can do some work without noticing the system, because in case of errors it will emit sound.
The memory value configuration
The time will vary depending on the test load, and the VRAM test load. By default the system will only load 1 GB, usually smaller in size for current GPUs, or for newer versions of Video Memory Stress Test
If we want to make sure that this configuration is accurate, with the open program we will go to the folder where your files are located and create a file VMT.Loader.
A new window will be opened like the one in the picture above that describes the default parameters for the program to use. As we can see, we were marked with no specific limitation, in which we added that you always use DirectX and full testing.
We can now save a new batch or launch a program directly, when we will return to the original location. Now we're pressing Start to start the test, but first we'll have to answer two important questions:
This first one addresses the limit we just removed based on VRAM size, so we click right on Yes.
This second question tells us that we are at a decision XXXX x XXXX x 32, which should be our guardian's then. This means, therefore, that this decision takes more memory than a low-level decision such as the one recommended by 640x480x16.
Ideally, we should accept your offer to bring down the solution and thus have a free memory that I can explore. As soon as we click Yes, the system will start testing and will mark the remaining test time.
In our case it's more than 6 minutes, so it's not too long.
When this test is completed, it will mark the faults of our VRAM (if any) if we do not have a counter to zero and with this we can calmly fail, being able to direct our eyes to other PCB components.
