Probably because the board power is raised up higher than the stock bios.  Say your stock bios has a board power of 300W, and the modded one has a board power of 500W, and say you are using 330W, that would be over 300W so 110%+, but under 500W so only 70%. 

 

Those are just example numbers.

Ive been trying to overclock stability for a week; with an asic of 88.5% I was hoping for something. if I cant seem to find the issue to the power limit cap; Ill just revert to stock bios with stock speeds and just pickup another 780.

ehhhhhh... As games move into 64 bit format vram usage will go up. It's been a pretty steady trend over the past few years. I can go through the years in my steam log & watch the v-ram usage steadily climb. Specially in high res/multi-monitor.

Just to add Anubis; I even dropped the powerlimit to 110% on the custom bios; and its still stuck. Dropping the voltage below 1.212 seems to drop the power limit more. The card that I have is an asus 780 directcu ii

That should be a pretty good clocker, all the Kepler cards I've had over 80% asic, were good clockers.

Oh, one of those cards, still should be descent, but aren't they limited to 1.212V?

Correct. Asus GPU's are limited to 1.212, even with the voltage crack. Due to the kickass buck controller, or w/e it's called.

if skyrim passes 3.1-3.1gb vram, it will crash. this is a well known skryim "bug". cant really call it a bug, its part of the game engine and will "never" be fixed. never as in maybe if hackers out there find a way to mod the game.... but the dev team will never fix it. other than that, obviously because of texture/mesh mods skyrims is by far the most demanding vram game ever released.

other more modern games with modern engines like (insert heavy dx11 title here) should just offload the excess vram onto the system memory and wont "crash" but will start to bog and fps goes to the floor.

this is one of the wierdier of the 780s Ive seen. The clocks start high on stock, and then as time goes on; the core clock slowly drops down. This card will boost initiatly to 1058 on stock bios with no power limit increase and end down at 1019. Even if I overclock; same thing happens. Im thinking that their Digi +vrm is doing this to keep the card cool . Since the card isnt returnable and I dont really want to flash between bios anymore to avoid damaging the card, Im going to stay at stock.

I thought that 3gb limit was system memory and not vram. Maybe I misread or heard wrong.

hmmm, lemme look into that, last i knew it was a frame buffer related to vram.

edit: comes to think of it, i dont think its system memroy at all because they came out with the 4gb ram mod like a month or two after it came out, then bethesda fixed it... but still let me look.
