The GTX 280 (made by XTX) card I am using for CUDA development is producing lots of errors using the memtestg80 (https://simtk.org/home/memtest/) tool. I tried with different drivers, OS-es but the memory errors are reproducible everywhere (see attached the output for 100 test iterations over 900 MB of memory). Moreover, the weird thing is, that during the test iterations the number of errors seems to slightly increase. Even more interesting is the fact that when I downclocked the memory to 1000 Mhz, I got ~7.5 times less errors and at around 940 Mhz I got ~150 times less errors then initially.
Has anyone seen similar behaviour? I wonder whether only this particular card is faulty or maybe GTX 280s are generally more unstable?
PS: the XTX GTX 280 is the standard not the factory-tuned version.
