SO while running the little built in gpu rendering program built into gpuz and looking at the PerfCap section in gpuz, it goes solid blue and says Voltage....... Im not understanding why its doing that, i have the slider set to 110% power, am i correct in thinking this is like a bios thing, and unless i want to flash the bios, im not gonna over come this?? Also, why dont i see temps for the VRM's in gpuz like i saw for my 290's??? my 980Ti's are eVGA SC's.. would really like to see the vrm temps, is there a program that can read it?

It means your clock is as high as it can go on the set voltage. The power limit slider doesn't have anything to do with that.
Is it "vrel" or "vop"?

blue = vrel. Only way to get around that is to tweak the vbios on the card. All four of my titan x's run without any perf caps when loaded, my vbioses have been tweaked though.

You can get vrel before you get to the max boost voltage. Now if it was saying vop, which is max operating voltage, then yes...the only way to get more would be to modify the bios settings.

I apologize for jumping in w a question but I get vrel in gpu. Wat the best way to "tweak" the bios?

The vbios voltage table & power table will need to be modified. First two sliders under the voltage table (P00,P02) need to have matching voltages. Power table will need to have the TDP, PCI-E Slot, PSU PEG PCI-E Rail 1, PSU PEG PCI-E Rail 2 & Power limit modified to match the maximum your card is allowed to pull defined by hardware. e.g. Titan X has one 6-pin (75w) & one 8-pin (150w) + 75w from pci-e slot = 300w maximum. NOTE: Matching P00,P02 voltages will make the card run at that voltage when loaded so figure out what voltage you need to be running before changing the two to match one another.

NOTE: this is entirely different for the Classy and KPE cards.... For vrel you don't need to tweak the bios. You need to use the voltage slider and up the voltage. The slider likely goes up to 87mv, depending on the model of GPU you have, but it'll likely not give you that much. Most of the EVGA GPUs have a max voltage set in the bios of 1.256. The only way to tell that, is if you look at your bios file. When it's reading vop (and probably vrel at the same time), then you need to modify the bios file to get more voltage if you want to run higher clocks. If you want to look at your bios file, open up GPUz and push this button (see below). Then you'll need to download the latest copy of MaxwellBiosTweaker in order to read it. The table you need to look at to see the voltage set in your bios, is also pictured below.

thank you everyone for your replies. Is this normal for this card to have this issue? also, im @ +.30mv added via MSI AB, should i ass more Voltage?

I click the above button and it fails to make a copy. I have the latest v of tweak and same v of gpuz that u have . You were correct I addaed the 87v on the slider in prec but the highest v reading is1.237. My question is would the extra >019 v give me that much of a perf inc? I should also say my card is the hydro copper and my temp never goes above 34., and my corrent oc is 1487mhz clock and +500 mem.

You may need to use a different version of gpu-z or use nvflash to save a copy. Did adding the 87mv via precision/afterburner remove the pref cap?

Yes, it's normal for the card to have vrel perf cap.

It really depends on the card. Try enabling KBoost, raise the voltage slider all the way up, and the power limit slider all the way up, and use the sensors tab on GPUz. What does the clock speed and voltage say? That's the top and bottom lines. It should read 1.237, and should boost above the stock boost settings. You can use that as a baseline for your overclock. I'm not familiar with the hydro copper, but I'd almost bet they're a dual bios card. If that's the case, I'd look into getting a modified bios to increase the power limits and voltage. Maxwell scales very well up to 1.262 to 1.268v. They can easily handle 1.3, so.....those voltages are completely safe. The guys over at overclock.net make some excellent bios versions....google "zoson bios"...you'll find em.
