I don't feel like my card is in danger by operating at that temperature (65C) under load, and I know about the 95C throttling. I do however, want to make sure what I'm seeing is comparable to others running the 780Ti SC ACX on air near that clock speed, as I plan on pushing my card further and I don't want to waste my time (or hurt my card) if it's not cooling effectively as it should be. Until then I'll just keep shaking in my boots as I worry to death about my temps! ..... thumb.gif

Hi-o,
Me once again with the same Question.

Is it possible to you change (stable) Clocks in the"default" Skyn3t Bios,flash it and don`t get any trouble?

Can Someone tell me please.

Thanks in advance.

Different cards behave differently. I have an early EVGA 780Ti with a ~70% ASIC that runs at about 92C under full CudaMiner load. I have a new similar card with a ~60% ASIC that with the exact same BIOS/settings in the same machine (not adjacent, before you ask, no air intake restriction) that runs at 77C under the same load. Both have standard reference coolers on them, and both run at same clock speeds and voltages and have equal performance.

The only conclusion I can reach is that different cards behave differently under identical conditions regardless of what GPU-Z might be guessing about ASIC quality and environmental similarities.

You may find it interesting to know that a card's ASIC quality can change. I have one card that went from 73.6 to 72.2.

That is indeed a fascinating finding that casts further doubt on the meaningfulness of the already questionable metric that is impossible to scrutinise due to lack of source code.

Source code is out there. What GPU-Z shows is based off of a tool given by TSMC.

Also, ASIC on AMD is not the same as ASIC on NVidia. I actually think that ASIC quality is more about board power usage than silicon quality.

Got a link to the source, perchance?
I'm not convinced it's about power usage because I have a lower score card running much cooler, and heat = power.

I'm not 100% convinced either. But what I can say for sure is that BIOS changes do not affect ASIC... so why did one of my cards change? I haz no idea...

Why not simply add some gpu fans with high cfms. Just make sure you have some kind of filter on the intake to trap dust. I have some 1/8" cotton in a

sheet I'm thinking of trying. Gotta c if it's too much though...So far just blowing it out regularly has been all right, but time to take it a step further.

Looking at a number of different things I could use like a pleated furnace filter type of mat'l,...

Any suggestions would be welcome.

I have a Lian Li case which has a filter, but it's not enough with higher cfms.

I'm talking 60 cfm or higher. Mine has a 140 mm and I add a cpl of fans 120mm, about 60-70 cfms/fan when using more than 1 card or 2.
