I recently bought a Titan Black Hydro Copper Signature and i and trying to work on how the Overclocking limitations work. Obviously I don't want to over work something and burn out my gpu but I also want to know what this great machine is fully capable of doing. I have been working on a single card and tapping up the mV and gpu clock offset and it does getting up pretty high but I'm trying to research and make sure my particular card isn't limited more than anyone else's. When I get up a little over 1400mhz it becomes unstable and the drivers crash, freaking crazy machine, but is this a typical point where people would expect to see the drivers crash and is it normal for the drivers to do this? I am new to the overclocking world and my knowledge is rather limited and cant find much info on web about this particular matter. I am also aware I don't need and really shouldn't overclock to such extremes for most uses, this is pretty much just to understand what it is fully able to do. Edit: Is there a formula or some kind of guideline I should follow for a ratio of overclock mhz on cpu to gpu to prevent bottle necking? using x99 Deluxe motherboard i7 5960x core water cooled with a 3 section and single rad corsair AX1200I power supply

1400mhz on water is a very good overclock. You're somewhere around 20% over stock. Which is quite decent for a GPU. Bottleneck, is an overused term. There is no 'ratio'. Basically, since the CPU runs the show including telling the GPU what to render, the more powerful your CPU the better your GPU will perform. Of course, the law of diminishing returns applies. There is a significant performance increase going from say 3.3ghz to 4.4ghz on your CPU. Going from 4.4 to 4.6ghz, will net you only a FPS or two. Personally, I value absolute stability over an extra FPS.

Can you clarify what you mean by "3 section and single rad?"
The card overclock sounds pretty darn good to me. Sounds like it is a winner for sure.

You can laugh and joke but NVIDIA use best GK110 for Titan Black. For me is important build of card and class not only pure optimization for selling. I think many people will agree with me than on of biggest NVIDIA's sin is because they didn't allow 6GB on GTX780Ti Classified and GTX780Ti K|NGP|N Classified. Because if someone ask me to give price on package, build, look, design I would say that GTX780Ti Classified and KP version are 300-400$ more expensive than GTX980 ACX 2.0 and 200$ more expensive than GTX980 Classified. Titan Black SC have 6GB and still is most complete NVIDIA card on market and graphic card at all. HydroCopper have even higher clock I think. When I say most complete I think on video memory, speed, etc... Only better option is Titan Z but that's 2 in 1 not performance of one graphic chip.

In keeping with the OP's post, is there a recommended voltage limit and typical OC clock for a Titan Black? I'm also curious to know how one stability checks it, because when I tried OCing mine EVGA's OC scanner couldn't find a problem but the card was not Folding stable. I believe that was because EVGA's furmark tests greatly underclock the card, but none of the remaining artifact scanning tests that run the GPU at full speed seem demanding enough to generate errors.
Have water, will cool.

Best from stability testing is 3DMark 2013. You start all test and leave to finish. If everything pass fine card is stable, is somewhere stuck and show some message card is usually not stable. You can test with 3DMark 11, Unigine Heaven 4.0 and Unigine Valley 1.0 too. Increase PT on MAX, and set clock and voltage how do you want. You are right Kombustor, Furmark, EVGA OC Scanner are not accurate for overclocked card because no PT freedom and card will boost on much lower clock than in games, folding or benchmark tests. You know that some voltage mods are available on net for all version of GK110. If you ask me I would concentrate on max voltage available through software. I mean on AB and Precision X. 1.300V is probably max safe voltage for card under water as Titan Black but I would stay up to 1225-1250V. Anyway without unofficial BIOS to prevent power limit, 110% PT could be limitation before than voltage sometimes.

Says the guy running an air cooled rig with 2 770s. LOL. To the OP. 1400 is a nice clock on your Hydro Copper Titan Black. If it's stable that's a good place to be for day to day performance.

Anyway without unofficial BIOS to prevent power limit, 110% PT could be limitation before than voltage sometimes.
I would think a more "synthetic" GPU load test would be better? But of the live 3D demo/rendering engines, I've found the Unigine Heaven benchmark to be quite telling in terms of artifacts and crashes. It seems to let me know pretty quickly when I've crossed the stability line, at least as far as gaming goes. If I can get through that a few times back to back without any issues, I can be stable for any game I've tried. I mostly use my Titan Black Superclocked cards for crunching for BOINC though (roughly 90% loaded 24/7), so that's a whole different story. Either way, 1400MHz is a nice OC, depending on how stable it is. Safe voltage levels for GPU longevity isn't within my expertise though, since I just set the power target to 106%, temp target to 80 C°, prefer maximum performance in the Nvidia control panel, and leave my GPUs at 1124MHz. I've only pushed them stably to 1275MHz (+152MHz offset) without upping their voltage. They're in SLI and using the stock coolers.
