Hey, I'm overclocking my R9 290 with Gelid Icy Vision cooler using MSI Afterburner.

When I run furmark, I sometimes get this strange glitch where the FPS and temperatures drop by like 50% for a second or two, and this happens intermittently. However, when I run Unigine Valley with the exact same settings, it is perfect and has no artifacting or any other issues. So, I can achieve an enormous overclock if I benchmark in Valley, but not if I use Furmark.

Also, I get artifacts starting at much lower settings on furmark, where they are still not present in Valley.

What to do?
