So I read that Kingpin said that Maxwell doesn't scale well with voltage. So is 1.274 not a good spot for these cards? If I pull the voltage back will it get higher clocks (obviously not going to pull the voltage too far back lol) just curious guys


It may/may not help. You'll just have to test it out.

Things are quite a bit different between the SC, SSC, FTW models and the Classy and KPE.  With the SC, SSC, FTW models, if you go into the bios and set them to run at 1.275v, it's quite possible you'll see a little more core clock.  With the Classy and KPE, setting 1.275v in the Classy voltage tool will likely lead you to a giant heaping pile of crash.  

Just an educated guess, as to what the difference is, but I'd GUESS it has to do with Vdroop / LLC in the voltage controllers.....as I'm sure if you read the actual voltage on the core of the SC, SSC, or FTW, they're running about the same voltage as the Classy and KPE, but.....I digress.  As I said...I'm guessing....

So, when he says, "Maxwell doesn't scale well with voltage, and the Classys / KPEs run best at about 1.87 to 1.2v".  Apply what I said above, do some testing in the bios files.  Find the happy place with your GPU with temps and voltage and run with it.

I am running version 3 of the bios in the OP and so far it works great with Bake in disabled for my 980 ti. Just wondering since I am pinned at 1.274v if I lower it a tad bitt can I gain a few MHz, maybe like 10 or 20... I would like to do the testing on that, but this bios is capped at 1.274, Sajin would you kindly want to take a look if you can give me voltage control on that one?

great bios so far

That would depend on your temps.....

This should give you control of the voltage via the slider.

Or...wait for Sajin.  = )

Looks fine to me.

umm... yeah I am stuck at 1.274 v still no matter where I slide the slider on over volt

Google drive a copy of your stock bios file and link it here.

this is the one I am using atm and it works great, could you guys throw voltage control into this one?

Can anyone explain to me why setting the PSU PEG Rails so high on the power table doesn't cause any harm even though they're set to values higher than the rated outputs of 8 pin and 6 pin pcie power connectors?

Here, try this.  I wasn't sure why what I did to the other one wasn't working, so I dug up a stock one for reference.  This should work.  Don't forget though, that if you have the power settings in the driver set up to performance, instead of adapative, there probably isn't going to be any changing it...same for kboost.

6 pins can easily handle 150, and with a good PSU, handle 200 and even higher.  8 pins with a good PSU can handle up to 300 watts.  The spec on the 6 and 8 pins are the minimum standard....in order to be called a 6 pin PCIe connector, they have to be able to deliver 75 watts, and the 8 pins have to be able to deliver 150 watts.
