@ 780 if you don't have it modded bios you are very limited to to any high clocks and be stable at it. The gain is much over the stock. but many found not much gain because they have a weak GPU. This is the problem with some ppl they don't face that they have a weak GPU. You are righr about the Power target in the 780/Titan at stock we hit the wall at 1215 Mhz and start to throttle.
with boost disable gain are between +13 to +39 score gain about +200 marks and Up. it does make you bench running a flat line when you set the core where you want. no drops during bench "only when bench changes the # stage" many of was have and memory weak, 760 and 770 has the best OC memory around, our GPU are very binned in terms of memory.
I did sent you a rev 3 of my vBios based on MSI lighting LN2, It can be flashed on DCII but I don't know if it will behave like DCII bios, it should because the value of voltage and power limit is the same. it only changes the % for ex: 109% some GPU to 115% on another.
but let me explain something here that i had to
they heads to understand it.
Many GPU has different slide on "Power Limit" is for fact 109% to 200% "aka 300% on AB"
the same amount of Power TDP 200% to 300% % can be on 109% , ppl thinkg the more slide the more juice it has, NO they are wrong, I can set "900" TDP on 100% or 300%. I was had that talk with FtW420 a few days ago about it cuz many ppl was drive me nuts about it, but happy now that everyone there had understand how it work's. so before we get to the Power limit we do need to know how the bios itself work because it must be set depends on the usage and feedback , I cannot just raise everything up and expect to be the best.
Too much voltage throttle , less voltage throttle too, same for Power limit. it apply for GPU and CPU, who know how OC works would agree with me. I'm not saying this is your case but many around here. this is why and how ppl in the 780 thread support others , right now I don't need to give support at the 780/classy/titan thread everyone there know how it works and give tyhe support for noobs or even the experienced users "even me get's help"
I'm here because you and all put me here not because I come alone.
support and feedback is the most important thing in a community. no difference between you and me.
lol I think I had spoke too much yeah...
Hey, since you guys are hotwire I will cook the DCII for both of you. i will pm both of you with the DCII modded.
