youll always see a 5c or better drop with good paste and good application
Try lowering the vram a bit, core clock vastly outweighs vram oc on a 384 bit bus.
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 ??
The performance wasn't needed.
After a massive all night session of tweaking and gaming, I found my pixel perfect 100% stable overclock.
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.
You tried memory at stock?
What do you mean by stock?
Of course. Ran the card stock first couple days I had it.
I think he means stock memory with overclocked core to make sure that's stable.
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%
Just telling you what I think he meant. No need to roll eyes at me.
That's what I would do, exactly what agent said.
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.
Sorry, guess I'm going blind. :wanker:
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.
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.
