Hello everyone
i am using msi reference skynet 780ti bois for my reference 780ti card
skynet gpu freequency is 928mhz
i have tried to modify bios for my stable clock cause i dont like to use afterburner
so
i test my card and i know that my stable clock is 1267 mhz
so i use kepler bios twearer 1.27 and modify boost limit by slider to 1267mhz and TDP base clock by increase button to 1267mhz
also i change all 600w and 300w tdp to 400w in power table
save and flash
but now i have only 1150mhz in 3d with perf cap reason vrel with vop in gpu-z monitoring
i deside to try to increase boost limit clock and tdp base clock to 1300mhz to have something about 1180mhz(as i think) but the windows would not boot with such high freequency. 1300 is not stable for card at all for stock voltage

how can i make the card to work at 1267mhz from bios?

I'm not really sure but I made a couple of bios's that you can try. Option 1 has the gpu boost limit set to 1267 Mhz with the power tables set to 400 watts with increased gpu core voltage up to 1.21 volts. Option 2 is a little more relaxed as the gpu core voltages have been left at defaults also it has slightly different gpu clocks as the boost limit is still at 1267 Mhz but the boost clock speeds are set to 1202 Mhz. This way the card can boost up to 1267 Mhz but only if conditions are perfect and some may not boost that high.

Give them both a try and see which one works better for you. Also if you feel the need to modify my bios then go ahead and do what you need to do in order to get it just right.

I also raised the max fan speeds on both to 100%.

thank you very much!
ill try them both
i forget to say - my card is watercooled with fullcover, the conditions are perfect)

Hmm
i tried both bioses

Hmm
i tried both bioses
both of them boostimg my card only to 1084mhz with the same perfcap reason "VRel, VOp" in gpu Z
gpu temperature under load is 33C

i fount that 1150mhz with my modified skynet bios and 1080mhz with your bioses are all 37 position in "Boost Table"
in "voltage table" CLK 37 set to 1025mv - 1225mv in all bioses

why card is stopping at 37 boost position?

cause of ASIC quality
so i needed to move boost clock slider to 1267mhz at 37 position
but this slider adjusts all another position freequencies
so i opened modified bios by hex redactor
opened original bios by hex redactor
and copy 2-36 positions from original bios to modified

now i have 1267mhz stable boost clock
and perf cap reason in gpu-z is empty

maybe you could make the same for 1293 Mhz?

Zup man. I used the custom BIOS you made for me with the increased power tables and the rest left to default and it seems to be working just great! No crashes for now. Will have to test more but 8hr benchmarks (I had to stop it myself) are way better than the previously 1.5hrs crashes

Thanks!!

Hi all ... thanks for all the valuable knowledge in this thread ... I just got my 780 Ti 2 weeks ago .. price had gone down alot since Pascal release.

After I extracted the bios using GPUZ from my ASUS DirectCU II 780 Ti ... I opened the bios with KBT 1.27.

Unfortunately, the Boost Slider was greyed out so I couldnt modify anything in the Boost Table tab ..
I couldn't move my target frequencies to Clock 35 (this is the frequency where my card wants to target for some reason)

After I hex-edited the bios ... the slider now works.

So for those using the same card and unable to shift the Boost Table ... I attached in this post my bios ..

What's inside this bios ?

- Everything as per Stock settings except
- the Boost Table can be shifted (move your target frequency into the Clock 35 box
- Power limit is now 300W (default) and 375W (can be selected in AB/GPUTweak)
- Boost States is modified accordingly too

My OC is quite mild (+100MHZ over stock Boost clock .. my ASIC level is just 60%) ... so I just simply shift the boost table, adjust the power limit and edit the Boost States accordingly as the photo..

I prefer to let the card manage the Boost Clock/Voltage while I manage just the temperature (tuning my cpu/case/gpu fan)

Hi all residents of a 1650 page thread. I have a 780 ti eVGA reference card that I am looking into overclocking to get a little more life out of it.

I just recently received a brand new h100i v2 corsair AIO cooler that I have no need for at present. I want to integrate it with the hg10 NVidia 780 bracket for this card, but I have not bought this bracket yet.

Also, I am not opposed to using my current h220 swiftech AIO unit and adding a waterblock to the loop and not even using the cpu cooler itself. Basically, I have two full AIO coolers that I want to use for both my CPU and video card. Your recommendations are welcome. By all accounts the hg10 N780 bracket works well enough, but my h220 swiftech AIO is just collecting dust so I'm trying to use both.

Can you guys give me any advice for which BIOS to use if anything other than stock? I think my card is reference:

Base Clock: 876MHz
• Boost Clock: 928MHz
• Memory Clock: 7010MHz Effective

And with a water cooled solution, what should be my reasonable expectations / starting points for an overclock on this thing. I'm not trying nor need to get anywhere near what some of you Classy guys are getting, but I figured I can get something considering I have a low cost water solution at hand and from what I read here, the 780 ti is one of the few cards out that that actually benefit from a overclock.

Appreciate the advice, I am trying to digest the entire thread, but there seems to be an army of BIOS recommendations out there.
