hey guys. ive had my 780 for about a week or so. i thought i would give overclocking a go and i dont seem to be having much luck with it.
i have the evga 780 sc acx. stock clockings are 967core 1502mem 1020boost
i just bumped up the core +100 so at 1067 now and everything else is at stock. works great. i thought well ill overclock the memory. i've read online that you should be able to add +200 to +400 to the memory easy. well i went all out and did +400 on the memory bringing it to 1702mhz. in games and or heaven benchmark it goes well but after say 10 minutes or if i start just manually going around the benchmark and toggle wire-frame or tessellation or whatever my game or benchmark will lock up then come back and my card will be back at stock clockings. Sometimes i get an pop up error saying there was a DirectX error or something. i dropped the memory to +200. same thing happenes. dropped it to +100 and still happens but may take a minute or more longer to happen.
power target is at 100 linked with temps. my temps ever go past 67C so it cant me that. i guess i didnt get samsung memory chips in my card
i did not touch voltage.
whats a good overclock on stock voltages?
