Thanks for this information ! I never tried to overclock VRAM that much before. Thanks to you I tried values I never tried before and achieved a +700Mhz value on Afterburner for my EVGA 980ti SC+ and now I am running at 4206Mhz for the VRAM and 1501Mhz for the GPU with the EVGA SC+ custom BIOS coming with the card (no handmade custom BIOS). Great !... For info I am just using a custom air cooler, a Raijintek Morpheus with 2 Noctua NF-S12B Redux-700. BUT ! 50% gain on the GPU clock ! And nearly everyone is achieving +40% with their 980ti... Why on hell NVidia is hidding so much power ??
After a massive all night session of tweaking and gaming, I found my pixel perfect 100% stable overclock. 1475 core 8748 memory Couldn't get 1500 stable no matter what I tried, even modding power limit in the bios to 125%. Overall I'm extremely happy with this card. Temperatures are great and power usage is less than my old 7970.
:3eyes: 1) Overclock core. Find stable. Method : Up core till artifacting, then add a bit of voltage. 2) Overclock ram. Find stable. 3) Wanted to get a bit more from the core so I mod bios Power Limit to 125%
Wasn't rolling eyes at you at all. <------ rolleyes smiley Was more of a, kinda miffed at the train of thought.
About the RAM overclock. Since I have a reference card I haven't been running crazy clocks on the core 24/7. I have a ROG Swift monitor and personally in FPS games I do feel the difference when I overclock the memory. So I believe that at least with older/lighter games or lower settings for better FPS, you do get extra smoothness from a memory overclock. Maybe I'm nuts, but I am super sensitive to the smoothness in games.
Just to add something here. It may have been mentioned before, but sometimes overclocking the vram on these cards can cause a massive drop in performance. I was running my card at 1510MHz and applied a 300MHz OC to the memory. I thought everything was fine, until I ran firestrike and scored 4000 less. Now, I've dropped the core to 1501 and added 400 to the vram and it's absolutely flying. http://www.3dmark.com/fs/5472300 vs now http://www.3dmark.com/fs/5492415 Edit: Added Firestrike scores
So I kept having Witcher 3 close on me with no crashes so I uninstalled 353.30 and installed 353.12 again. At these same clocks I no longer have the game close on me and I get a constant 99% GPU usage but now instead of a steady 60fps I get drops to 48. So I don't know wtf to do anymore.
980ti drivers are not great at the moment I believe nvidia is focused on Windows10 and only doing what they have to with windows 8/7 I plan on running windows 10 so hopefully the drivers will be better.
Yah I'm planning to move over to Win10 maybe 2-3 weeks after release... want to be sure no major issues are in the release version before install.
