Yep, as the topic says I can't seem to OC from 900 mhz to 905 mhz using overdrive. It was working fine yesterday. I played Crysis at 790/1100 (core/mem) but today, the monitor starts blinking (as in some random distorted crap shows up on the screen for a split second and goes away every few seconds) if the memory goes above stock at all. The core still goes to 790 just fine. The card doesn't even have to be stressed - even WarCraft III blinks! I don't get it. VisionTek model bought yesterday - no BIOS flash, stock cooler, only OCed using CCC. Anyone got any solutions/ideas?

4870: screen starts "blinking" if memory goes 5 mhz above stock (in CCC)!

What drivers are you using? XP or Vista?
It's at 30% constant (set in the XML file through a CCC profile). 60 idle/77 load cause my room is hot but that's still cool enough. Heat shouldn't be causing artifacts at 905 mhz on memory. And as I said, this was working fine for hours yesterday.
