    The way you word that suggests that overclocks higher than 2200mhz are unlikely to happen because of the voltage lock, I don't think that is the case. Overclocks over 2200mhz are probably going to be rare, and like Maxwell will favor lower voltages.

    The "thing" that makes ICs fail at high clocks is closely tied to temperature; there are also architectural factors that affect the clocking.

    For the sake of the argument let's imagine the GPU as a huge 2D matrix that represent gates. The GPU is a hugely parallel machine, so you can imagine that the thousands of independent paths (from input (top) to output (bottom)) represent the longest datapaths possible.

    The longest delay between any two "latched events" (when data must be "pulled" from a rail at a clock edge trigger) must naturally be shorter than the inverse of the clock rate by a reasonable amount. If not there will be confusion, errors, crashing and lots of frustration.

    Other than the physical propagation time of the signals (hence path optimization in pascal to allow for 2ghz+) you also have to factor that transistor gates themselves present an inherent latency called "gate delay" that increase with temperature; but I'm not taking about the GPU temperature. Local temperatures; "instantaneous hotspots" will affect gate delay before your average cooling solution can dissipate the heat away.

    This is why LN2 will probably be the only way forward, because much lower average thermal energy (overall chip temp) means local hotspots will dissipate more quickly

    What I have written above is why even on water 1600mhz 980Ti is hard because you want to keep it below 50c ideally, of course it depends on the chip and the voltage you need to sustain such a clock, but as a general rule if you can keep the GPU core and VRMs cool you will have more success for those overclocking 'fringe benefits'

    At the end of the day when someone complains that GTX 1080 "sucks for overclocking" you should realize it's a very petty complaint, because it's entirely contingent on where on the clock scale NV decided to stick the "stock" mark.

    The stock boost clock is 1733mhz. They could simply lock the clock at 1733 and not let it rise above that. You could overclock it to 2100mhz and everyone would be impressed. Instead it clocks out the box to 1860mhz so you're less impressed with the OC but the performance is the same.

    The MSI PCB looks like the same one used for the 980 Gaming. Maybe it will be the case. The 980Ti Classy used the same PCB as the 780/780Ti classy therefore the FC water blocks fit.

    If this is the case with these cards I'm not so anal that I would be upset about my 1080 saying 980 on the water block. Hell my 670 water blocks say 680 lol.

    You are talking about a fringe minority with LN2 though I'm referring to a slightly larger minority that being watercooled.

    No no, this applies to watercooling people too. Like I said, watercooled 980Ti @ 1600mhz + is made possible by lower temps

    Like if you can sustain 40-45c LOAD on the GPU you can comfortably run 1650mhz provided the chip actually clocks that high.

    This guy can run 1680mhz on BOTH 980Tis if we he leaves memory at stock. 1680mhz. 45c load.

    Basically as far as pascal is concerned, the maximum clocks achieved by the reference (FE) version are more or less the maximum you'll see on high end air and water. Golden samples may hit 2200mhz and be able to sustain them. It isn't a bad thing, it's the same as 980Ti really.

    The only thing is people consider it a bad showing because the 980Ti overclocked more in %. I mean nvidia could have said 1050mhz stock. That's 100% overclock. best overclocking card in history.

    Yeah, but noise is a huge concern as well. To be fair though, a GPU core with such high clock speeds is unprecedented!

    Six months ago I remember people thought I was crazy for suggesting that Pascal would easily hit 1.5ghz clock speed. Turned out I was low balling :grin:

    Where you get the review of the Strix? I preordered mine on the 27th and i have been advised first cards will not arrive in the UK intill the 10th of june, a far cry from ASUS's press release of available on the 3rd which from announcement to availability is well over a month disgusting really. Oh well guess it gives me plenty of time to cancel if need be.

    Ah i see. Bet you wouldnt have bought that 980TI if you knew that upfront.
    It is pretty high settings you are running there though.

    Thanks for the great article. This was the 1080 card I had my eye on and this just confirmed that this is going to be my 1080 card. I can't wait for NewEgg to get them in stock :)

    Fine, two generations old.

    And since nVidia were showing a demo of a "randomly picked card" running at 2114MHz people were obviously thinking that AIBs would be able to add another 150MHz on top of that which wasn't true since FE clocks about the same as any custom PCB card. nVidia were clever though locking the fps at 60 so the GPU load would be low enough for the card to sustain such speeds without crashing.

    Yes, that's what they're saying and is also the total available headroom that Maxwell theoretically had. That's why the Pascal cards are not overclockable beyond factory OC, there is no headroom left.

    To repeat myself, 1080 is not a bad card by any means. For those sitting on 980 or even 970 SLI (taking average scaling into account), this is a very nice upgrade.

    I couldn't imagine those settings with my old 780gtx, this 1420mhz 980ti and looks like 1080gtx just about holds it steady, but there is always moar, idk crank that SSAA higher or raise GTA5 foliage to ultra while keeping 1620p and still get 60fps vsync all the time :D

    1080Ti would be ideal, but now I think I will pass that too, usually keep gpu for ~2 years. Just in time for Volta and AMD Navi :nerd:

    I am itching for a new card. A 1080 would be a huge upgrade for me. Hell I may put a 1080 in the main rig under water and a 1070 in the second rig as they both are due for an upgrade.

    but if you really want that extra omph then wait until 1080Ti (Q1 2017), worst case TitanY first in Feb-March, 1080ti in June. And extra 150-200$+ compared 1080GTX for sure, but at least "worth" it

    yeah in 2nd rig put custom 1070GTX e.g. like this reviewed 1080 MSI Gaming:nerd:

    Thanks,

    Pretty interesting, the MSI and ASUS are more or less on par with noise and thermals but the ASUS card is clocked higher. Although Computerbase seems to have slightly higher internal temps compared to guru3D. Still looking at the MSI card it would set me back £650 while i have spent on the ASUS £620. The ASUS card has almost 100MHz extra boost clock also (averaging 2GHz frequency).

    They have the Inno Airboss too, what i find interesting is both seems to be power target limited. Seems that extra 6pin power connector is useless then and is more of a gimmick.

    Although i must say memory overclocking looks pretty disappointing too 1GHz overclock but better than nothing i guess, both are using dual VRM's for the Ram.

    It's really hard to tell which card has the better thermal solution, as the test bench and ambient temps are undoubtedly different.

    One thing is certain though. A case with poor ventilation will stifle any GPU no matter how good the cooling is.

    Case ventilation is one of those things that not many people consider, but it has a massive impact on component thermals. My GPU has NEVER broken 70c....ever. And I attribute this not only to its awesome heatsink and fans, but to my case ventilation.

    On another note, I'm waiting to see what Zotac does with it's Amp Extreme model. The Amp Extreme heatsink and fans are perhaps the most capable air powered thermal solution for GPUs I've ever seen, if a bit cumbersome.

    But then according to Videocardz, the GTX 1080 Amp Extreme has just a mild overclock compared to the Strix Rog..

    Fingers crossed we'll have a GTX 1060 with 4GB before the end of the year.

    You know, once Nvidia get to 60 level (760, 960, etc...), AMD has much better offerings. (280, 380/x, etc...)

    480 was announced in the price range of the 960 and probably the 1060.

    It seems that since the 600 series or older Nvidia cards have been locked in such a way that the model u get doesn't seem to matter on oc aside from a few boards that are temperature limited. My old reference gtx670 with its h70 cooler and bios mod oced just as much as premium baords.

    The 4GB variant of the GTX 960 had no effect on benchmarks. The 960 lacked the raw horsepower to reach stable FPS at 1440P/4K, so increasing the ram meant nothing.

    Not at you in particular, but at this notion to wait. We could write some variation of ^this^ sentence for every king-of-the-hill GPU release. There is ALWAYS something faster coming in 6-12 months. There is always something more reasonably priced coming down the road too.

    Rinse. Repeat.

    Realistically, after the Titan ($1000?) in 6 months and ultimately the 1080Ti ($800?) release in perhaps a year, that's a long time to wait. AMD can't seem to find traction in the high end.

    Many folks want this GPU speed now. We need more power , Mr. Scott! Not 6 months from now, maybe. As with every new release, many are fine with paying a premium for the best. the 1080 is clearly the best. A 4K beast.




    I think the biggest problem right now with this release is timing, we are transitioning from 1080p to 4K. Many people need to buy monitors (even 1440p) with their new cards or it's almost pointless to have so much power. The GPU market and enthusiast monitors, overall, just aren't quite ready. The 1080 is the best yet though and by a clearly significant margin.
