Something I have noticed about these cards, they are great but they have a issue. For me they appear to overcock and function great for even heavy gaming, but under OCCT testing, with even slight overclocking I get errors. Not many errors mind you but errors all the same. This has happened on the all cards I have owned from MSI Twin Frozer line, 5850, 460s and now 560ti s. I have heard this is from the voltage regulator overheating under stress testing what do you think? FYI at stock they were all error free even under OCCT. Also has anyone noticed the same issue and how the heck does kombuster work does it report error?
