I was getting slowdowns like that in GTA V and Crysis 3 and few others where my framerate was dropping way below 60fps and GPU usage was going down.
And that was with 2500K@4.8Ghz

Like I said that is probably because of RAM - check out this article by HardOCP using the same RAM Speeds.

All I changed in that bios was disabling the auto boost. If you look in the common tab entry point are all #0 and the boost clock says 1405. The stock boost clock is 1405mhz, I don't know why yours is 1380 when mine is 1405. Just try my bios and see if you can overclock higher, if not then you're out of luck. You're not guaranteed too get better overclock than a reference card by the way, that's not how it works. You've either damaged the card by ******* the button on the back, or have a bad bios. either way the base clock on this card at 1405mhz is still much higher than the 1200 or so on the reference model, and most of them only hit what we have. Others? won the lottery. Just because you buy this card won't secure you winning the lottery.

Just try my bios and see what you get.

Is your card under water or custom loop?
my card always boosted to 1380Mhz, its because i got a 64.5% ASIC and its air cooled, the button on the back is useless, its just a bios switch, i never used it anyway, but yeah, 1405Mhz is the boost clock for ur card, and turbo boost 2.0 wont overclock my card higher if it dont feel it can handle it, this is why ur boost is higher than mine, just like my 750ti FTW, max OC was 1411Mhz and i saw a guy with another 750ti which boosted to 1411Mhz out of the box, what i cant understand is how its possible for both my gpu and vram not overclock high enough, Mr-Dark has a 980ti strix and he said it can reach 1430Mhz @1.28V, but now that i got the voltage unlocked and after doing some testing i think my card can reach 1430Mhz but stock memory, i even tried 1.3V and it wasnt stable (with memory set to 7.2Ghz).
980TiHOF.zip 152k .zip file
this is the second bios(the one u enable by pressing that button on the back) that came with my card.

For what it's worth, my ~65% ASIC 980 ti won't OC well either. The Witcher 3 even put a stop to my 1400 MHz OC so I've settled with ~1380 MHz for now.

Silicon lottery sucks 😥

it crashed at 1400Mhz on witcher 3? WUT! now im scared '-' cuz lek, im gunna upgrade my CPotatoU and i'll kill the bottleneck so.... i tested on GTAV and JC3, both on ultra @4K for as less bottlneck as possible, did u try increasing the voltage to see if it helps? it did nothing for me except for the extra TDP

In this article I can't see either GTA V or Crysis 3 or any other CPU intensive game so I don't know what are you trying to point out here.
Ram that I have now is 2400mhz and my sandy bridge system had 1866mhz with much tighter timings so I highly doubt that it had anything to do wit the slowdowns I was experiencing.
Reviews don't tell full story because mostly they only benching one scene in the game and not the whole thing as when you play it from start to finish.
I was getting fps drops to mid 40 and now I'm staying way above 60 all the time.
Besides his CPU is 2500 non K so he can't overclock it and mine was running at 4.8ghz and in both these games when I was experiencing slowdowns my CPU was reaching over 90% usage.

You want an example.? Here it is
Skip the video to 2:05 and you'll see that i5 4690K drops to 52fps where i7 4790K stays well above 70fps and all the other component including RAM are the same. So how will you explain this.?

Of course there are games that are CPU intensive which the newer chips will perform better on. As for GTA V that is a mess of a game with hitching videos and frame rate issues.

As fro your RAM comparison, that's precisely the point I linked the article from HardOCP, which shows that going from 1866 to 2133 already shows a 7% improvement across games. Using 2666 Mhz ram it jumps to about 15% improvement. In your case since you're in the middle (2400 Mhz ram) the improvement across the board is roughly around 10% (min and average fps).

Obviously the Witcher 3 is a very CPU intensive game and the more cores you have the better the game will play.

I shouldn't have made a blanket statement, I should have said for most games which are non CPU intensive the CPU won't bottleneck a GPU if you play 1080p and higher resolutions (of course player with 120 and 144 hz monitors is another issue).

Here's another test with games this time and obviously they mention that for CPU intensive games is where the new chips perform better than the older chips

Higher voltage will actually reduce the core clock even more when it starts to throttle due to heat. You can't disable the thermal throttle, and with 1.3v there is no way you're under 80 degrees unless you're under a custom loop. Like others have said in this thread Maxwell is not better with higher voltage, it'[s better at stock or slightly lower. Try 1.194v, and lock the voltage to that to stop the thermal throttle lowering it.

As soon as my gpu hits 60'c is down clocks by 13mhz and lower the voltage by 10mv. The same happens again at 66'c and 70'c and 75'c then 85'c. It's just how my card down clocks/throttles. If I locked the voltage it would still down clock the core clock I believe, it was the voltage that crashed my card. the max I can get while in games is 1480mhz core, 2000mhz memory. While benchmarking I can only get 1450-1460mhz core and 1960mhz memory. It's just more demanding.

For me I haven't seen any increase in performance taking my ram from 2133mhz to 3000mhz. Maybe it's because my cpu/gpu aren't being bottle necked as I only play on 1080p/1440DSR.

http://www.tomshardware.co.uk/forum/268650-29-overclocking-series-core-2500

According to that post he might actually be able to overclock it up to or around 4ghz using a multi. BCLK is also an option, but sandybridge is so limited compared to skylake and haswell. If his cpu is 3.3ghz then that can cause some instability issues and may stop his overclock from going higher due to bottlenecking. I had that problem on a gtx 960 strix where the cpu help back the gpu in a friends pc.

well, my card doesnt throttle at all, and its 100% air cooled, what i did was ask Mr-Dark to increase my fan speed to 100% and it hits 3300RPM, not 3000RPM, u should ask Mr-Dark for a custom bios too.
