Ok funny problem
I don't know how popular it is but I found the original MemtestCL is a fantastic little app which can weed out even the most minute of VRAM errors. It is far more sensitive and precise than the old fashioned method of staring at the screen for artifacts. Unfortunately, it really hasn't aged well because from what I can gather from my extremely limited knowledge of software, the program has a bug with its internal routine where it tests Random Memory blocks. It something to do with how the modern AMD GPUs are so powerful that they complete the iterations so fast that the RNG generator can't read from the Seed fast enough. The result is that it incorrectly records an "error" when the seed read is missed.
Now, the original Dev has taken the Closed Source version, fixed it, and made his Open source. However, due to the niche nature of the software, I can't contact the original dev nor do I have the expertise with VS2013 to compile it (I've been trying for days).
I find the programming forums to be a little intimidating so thusly
I'm calling on the programming might (specifically OpenCL devs) of NoteBookReview to try and see if there are any additional problems with this fixed MemtestCL app and perhaps to compile it in to an .exe package for everyone to enjoy.
It is a great program that simply was forgotten in the sands of time.
Heres the GitHub link.
