post #11251 of 21377
Please can some give me some advice please ?

I see their is a .1 and a .2 of the bios skyn3t ?

Which should I use for my EVGA Classifeid 780 TI's ?

And then what does the bios actually do for my cards,ie I'm guessing it will unlock the card .
But what parts and to what level ?

IV read some custom bios are re set overclocks and others just allow the user to adjust voltage and power target higher ,, which is this and which is better .
I would like to see what these cards can do ,?but I'm not looking to overclock the balls out if them lol

But I am going to be gaming on them for 6 to 8 hours at a time , they are on the stock air coolers and I have a extra custom air cooling unit give a good temp.

Thx for any advice

Do what I did and pop the top on your 800D with a dremel - there's enough room up there to lay in four case fans with a nice grill, keeping the fans inside the case. (I went a little overboard with my 800D and also mounted a quad radiator, shroud and 8 GT 1850's for a push/pull setup. Adds LOTS of air flow to the case.

Giving some thought to just finishing the loop like it was supposed to be. Though it will be costly

I think my card is dying. I was running it with some 750 Ti's on the 335 driver with the Ti's mining and the TiC driving the monitor for Simulation CFD and I kept getting driver crashes. I'd disable the miners and still get the same result. This was with the Ti's and TiC at stock at since CFD doesn't really like anything else and there was no benefits anyhow. At least once a day I get stuck in a driver crash loop now. I haven't even ran overclocked in at least a month as I haven't had time to game.

I've since moved the Ti's to a new motherboard and stability improved for a couple weeks. Now it's crashing again with constant loops. The driver recovers and falls right back over until reset.

I've ran DDU in safe mode, reverted drivers to 332, no PX running, and no classy tool running. Once the card comes under load for a few hours, I get driver crash loops. If not under load, I still crash, only it's in the middle of the night with nothing happening. I wake up to my computer looping driver crashes. I'm out of ideas at this point.

I remember coelcanth (sp?) had issues with the drivers messing with voltages w/ a 750 Ti, but I chalked it down to bad luck, file, config issue. Maybe that wasn't a wise move.

Any ideas other than RMA at this point?

Upgrade to the beta 337.50 drivers. 332 doesn't support the 750Ti but 334 does and still doesn't run as well as the newest beta driver. 335 has been nothing but a giant ball of complaints since it was released. Read up on the drivers at EVGA and you will get better info.

Yeah, that is my next move. Only thing is it shouldn't matter. There are no 750Ti's in the system now. I bought a cheap motherboard and put them in there. The 780 Ti is alone now.

Let me cross my fingers and install the new drivers.

I am currently considering getting a 780 classified to run in sli with my 780 lightning because the lightning supply has totally dried up in my country. My lightning is already watercooled and the classified would be also. From looking at pictures of the mounted blocks, they definitely don't line up. I figured that I could just use some of my regular tubing and a couple barbs. Has anyone tried this?

I would be hoping to do maybe 1300 core per card. My lightning laughs at that low a clock, and I am hoping that a classified would also. Anybody foresee any issues trying this? I have a 1300 watt Evga PSU. Thanks in advance.

There also have been countless post about this as well and nobody has gotten GPU-Z to show correctly consistently - especially at higher than stock. The higher you go, the more GPU-Z is usually off.

All TIC cards load higher by .05 volts. Some will load slightly higher, but none will load lower much lower (as in nobody with a DMM has shown lower). Also, higher frequencies will pull more voltage than lower frequencies. This is supposedly more pronounced at higher frequencies and voltages. Hence why some people are .15 over what is set. Heat will also play a part as well, as the hotter the GPU is, the more inefficient it becomes. This isn't much more voltage, but it is enough that you should be aware of.

The danger with increasing voltage in my opinion is the increased wear and tear on the regulation circuitry more than the GPU itself. MrTooShort lost a golden Titan because a VRM blew, not from the core cooking at 1.4 volts. With memory, I'm worried about the memory chips because there are so many of them, and only one has to go bad for your card to be a pretty paperweight. You also have less phases/components feeding it, so any one piece causing spikes makes up a significant chunk of the power delivery for the memory.

If you are on air, eventually adding voltage will lower stability. The GK110 core is very temperature sensitive. Stability at stock may tolerate 95C, at 1.3 volts it could drop into the 60s on some chips.

I monitor my clocks using PX. There is no way to correctly monitor voltages without a DMM. I use GPU-Z to validate my card for the owner's club.

In respect to this, I was curious if i am running ~1.3125 on my cards with a pwm of 416khz for an effective voltage >1.4 (probit connector on my to buy list) would it be less strain running actual voltage with lower pwm or? I know either way there is strain on the circuitry but which is worse?

You could do something similar to what I did.

I'd guess the higher PWM offers lower strain on the GPU. It may put more strain on the components, but that is just a BIG guess. They could very well be equal. There are a whole lot of power phases to smooth delivery to begin with. If your on air, I personally would back it down a bit as RMA's aren't any fun. I'm staring at one right now and not to thrilled about it.
