Thank you. No, i didn't write that my card stinks, just has low asic reading (60.8%). And i have skyn3t rev 4 bios flashed already wink.gif Well, anyway, skyn3t increased core mhz from 993 to 1110.5, so i thought maybe he increased voltage as well, cause PX reads 1.2 on load. I'm not extreme overclocker, not under water, so don't wanna push it too far. Thought to go up to 1.212 and push as far and as stable as i could on that voltage. But PX reads 1.2, my card stable 1200/6k (didnt try to overclock memory yet), temps not exceeding 63, so maybe i'll try Classy voltage tuner, to push it a bit more.
Well, i thought about going only to 1.212, cause i'm on air. Thought i could do that on PX or AB. But every software program i used (PX, AB, Hwinfo, gpu-z) shows different voltage readings wink.gif And they dont change if i, for example trying to increase it on PX or AB. So probably skyn3t Bios rev 4 has 1.212 set already and only PX shows it correctly..
Thank you for that. I wasn't sure about it.

Actually, you're lucky it didn't roast your card. those commands are for the ON Semiconductor VRMs - only.

Whats up with the skyn3t rev4 bios for 780 classy its keeping 1.150 volt, even through I change it from MSI AB? Do I just have to use ClassyTool to change voltage?

Try EVGA Precision, 1.21v should be possible without Classy Tool. If that doesn't work reinstall your drivers.

Have you tried running heaven for at least an hour at max settings? I found that at 1440p + max settings in Heaven is the perfect test for stability. I usually run it between 2-4 hours. 6 hours if I have time. If it passes without issue, I'm good to go in any game.

Im running 24/7 clocks of 1300/1600@1.212v just using afterburner for my gaming. I have gone about halfway through crysis 3, quite a few hours of bf4 multiplayer, a little bit of borderlands 2 and a few long hours of very heavily modded skryim(soft memory modded) without any issues at all. I had always found with my 7950 that skryim on long hauls or crysis 3 for a few hours will fish out instability in an overclock. Im willing to bet at the 1350mhz core i wouldn't be fully stable in those two games, it was just a benchmark run.

Thank god it didn't happen! It was in "GK110 overclocking guide", I'm on GK110, so i thought its valid for my card. Need to do more research before doing something like that..learned my lesson, thanks wink.gif

Meh, run Heaven benchmark at max settings @1440p for about 4-6 hours. That puts a hurting on your card since it's at a constant full load.

Go back over the last several pages, there are discussions on this very subject.

Yea, I do plan on running a loop, unfortunately unless I want to order from EK directly neither FrozenCPU nor Performance-PCs currently have the blocks or back plates available. I'll definitely download the Classified tool. Thanks.

Since you're using a stock BIOS, we don't know what your clocks are when you say "+120" since you're using a boost BIOS. If you really want to see what your cards are capable of, then flash the skyn3t BIOS to your LN2 BIOS.

If you're cards are Rev. A1, then you can use Rev.3 skyn3t BIOS. If you have Rev. B1 cards, you can use skyn3t Rev.4 BIOS.

To save your stock LN2 BIOS, you're going to need NVFlash v5.142:
http://www.techpowerup.com/downloads/2258/nvflash-5-142-for-windows/

Then open up a command prompt and in the command prompt go to the directory where you have NVFlash. For ease of use I always just put it in C:\Classified:

1st step
Nvflash --protectoff
(This will disable the bios protection in order to save or flash a bios)

2nd step
Nvflash --save call.it.what.you.want.rom
(This will save the stock bios or vbios)

Don't use GPU-Z to save bios, some versions may save your bios corrupted.

For flashing a new BIOS:

Unpack the bios you want into C:\Classified (the same folder where NVFlash is). Then while in that folder right click in an empty space and select "open command window here" or run a command prompt from the start menu and then proceed with the unlock command below and the rest of the commands as needed.

nvflash --protectoff

nvflash -4 -5 -6 biosname.rom

You might have to hit "y" twice. Once it says completed reboot. You might also have to reinstall drivers depending on bios.

Flashing with 2 cards installed -

nvflash -i0 -4 -5 -6 biosname.rom - (This is for card #1)

nvflash -i1 -4 -5 -6 biosname.rom - (This is for card #2)

For stability just bench (Valley, Firestrike, Heaven) and play games.

For seeing how your cards stacks up against others I like going to the Valley and Heaven threads. There area spreadsheets in the OP with scores, though they are bench stable and probably not game stable. I have a pretty decent SLI score in there but it was artifacting during my Valley run.

http://www.overclock.net/t/1360884/official-top-30-unigine-valley-benchmark-1-0/0_100
http://www.overclock.net/t/1235557/official-top-30-heaven-benchmark-4-0-scores/0_100

Everything you need (except for a newer version of NVFlash) is in the OP of this thread including the Classified Voltage Tuner (direct download from here: http://www.overclock.net/attachments/19143)

Good luck! thumb.gif

Thanks for the thorough response! I'll definitely try out the SKYN3T BIOS. Apologies for not providing actual clocks; the "problem card" does 1240~Mhz/1650~Mhz but nothing seems to move it higher than that whether it's 75c or 65c, the second card will do 1300~Mhz/1650~Mhz and again it taps out regardless of temperature. I'll submit a GPU-Z validation some point soon, thanks again for the help guys!

Australian/Taiwan EVGA got back to me about my RMA. The card is completely broken and they are waiting from stock in the US to replace my card frown.gif

Looks like i'll be waiting awhile... sigh

This happened, couldn't even see the clocks or anything in GPU-z after it either.
