hey everybody i am steve from gamers nexus not nad we're here at Computex 2016 i want to do a quick live overclocking demo of some of MSI's new GT x 1080 cards so we talked about these yesterday in our previous video if you want to learn more about them what we're working on today are to 1080 Z's this is the top end of MSI's line of Twin Frozr 6 cards so they are effectively the flagship we're gonna just kind of see very quickly on the show floor how far they can go obviously this is as serious and overclocking test as you might get from our labs at home but let's just go ahead and set something up here so I'm gonna set up fire strike to run custom in the background I only want the graphics test to because the most intensive on graphics I'm gonna loop it I want to put it in windowed mode and we're just gonna run this and I'm basically going to keep it in the background while we tune some of the settings you can see here we've got three monitors setup so the scaling is a little bit ridiculous but we're gonna go ahead and launch that to start let it let it load once that's loaded in I'm gonna be playing around with msi afterburner which you can see right here and we're just gonna tune the clock settings and see how stable it is and where we're sort of the thresholds are for performance so one quick note this is an SLI setup which means it behaves a little bit differently for overclocking but we are gonna still go ahead and try this so 3d marks are almost done loading now it looks like our maxed 107 on these particular cards and I'm not sure if there's any limiting because of SLI but we're just gonna go ahead and start with this max I'm not applying it yet because I want to monitor the clock rate so you can see the clock rate right now 1987 megahertz and the memory is 50 54 megahertz it's an effective times to rate and then we have our tuning settings here so let's go ahead and apply the 107 for our power target and then we're gonna keep the temp limit at its max it's 92 I'm gonna start with a pretty conservative seventy-five megahertz offset and we're just gonna apply that and see if it remains stable so you can see I've got fire strike running in the background that all that's doing is stress testing the overclock as much as we can with a pretty simple setup I'm going to move there over a little bit hopefully doesn't crash so I move that over we've got afterburner here we're running stable right now 20 37 I saw it spike to 20 50 briefly I'm not sure where the voltage control is on this version I think it's up here it's up here so we can over we can over vault in a minute if we need to let's go ahead and just push this to a 100 offset hit apply see how that goes and it's it's not survived to that so we found the limit already which is about where the 1080 should be limited because of its voltage concern or the voltage limitations by on video speed BIOS and the drivers do automatically recover which is pretty cool this is new with the new generation so we don't actually have to restart to just start testing again I'm gonna launch this let it get started again and then we're gonna just back off that clock rate I should probably do that before it's loaded in here back off that clock rate to the 75 offset which seemed pretty stable one thing GT X 1080 the founders edition when we tested that it required 25 mega Hertz offsets for the clock rate so we're just gonna stick to that here I'm not sure if this can accept smaller offsets than 25 mega Hertz at a time I'm not gonna try and figure that out as a trade show either so let's let's do the fan speed first we got people playing on the case behind me so I'm gonna try not to hurt their fingers to a 72% fan speed just for safety and got the 75 mega Hertz offset core and watch this is loaded we'll go ahead and do the memory overclock and see just how far we can push that I want to review we were able to push memory to a 900 megahertz offset when using fir mark but that is not a real-world application so it's not really great look at things and the only way I could do that was by playing away around with the overclock on the core and reducing it to allow the extra voltage to memory let's start with a again a conservative 300 offset so there's 300 megahertz you can see we're still running here fire strike in the background it's not oh oh there's our instability so we found the limits again this instability by the way generally you want to burn in for about at least an hour to make sure it's good and ideally maybe overnight but we're just doing it all live here so obviously there's someone to take let's let me back off of this a little bit make it a little less intensive just to see it see if there's any difference here some of this may be SLI and I can disable that if that's part of the issue now we're back I was not able to successfully disable SLI just as a demo rig a lot of stuffs locked down cuz right a trade show I've already screwed up a lot of the stuff here so we're just gonna do as much as we can with what we've got because I don't have to rebuild the whole system so it's do another custom run graphics to loop windowed let's drop that to 2560 by 1440 run then this I'm going to back down to a zero offset on the memory fan speeds we're gonna set to auto just for safety because I'm not sure what was causing the instability these are unreleased cards after all so we don't really have the best idea of how they perform in a real environment but we've reset everything to pretty much stock one hundred seven percent power limit we've got the core clock it's offset seventy-five megahertz that's going to put us in a little over two thousand I think for the overclock it's pretty good overclock although the founders edition could get pretty close to that and in our case did exceed the 2088 alright so there we go we're at twenty eighty eight megahertz right now and that is exceeding well what we had for our founders edition and Tesla's canceled by the user it says it's just something something's not working here because of the sli setup I think all right so we're back again here's our fire strike window I'm gonna look at the overclock one more time see if we can get something to work here so we're offsetting this I'm keeping at 103 percent on the power limit just see how that goes try not to stress out the car too much 50 megahertz offset on the core let's keep this 250 and just see if it survives if not then we know it's an SLI issue with afterburner trying to keep them locked or something so here we've got the 50/50 it is applying about 20-25 boosted clock rate with a 5103 memory so it is actually working you recall we have 50/50 something before for the memory and we were below 2000 in the 1900s actually for the the core clock so this is functional now I'm going to cautiously extend this to 105 percent you see we're still alive back here and now we're going to go ahead and increase this to 75 which was functional previously so hopefully wow functional for the few seconds it was tested of course show floor and all so hopefully that's good looks to be surviving we're at 20 37 still 50 103 and it's died so that's that's I think the limit of what we're gonna be able to do here at a trade show I do with in theory have one of these cards back at home base already and we will be testing it more exclusively and more extensively in our normal test bench but it looks like what we're hitting here is about 20 20 18 20 25 for the core memory I'm not really able to see how far we can push that just yet so without SSL I should be a bit easier I think that's part of the problem that's our live overclocking experiment and thank you for watching patreon like the first all video if you want to learn more links in the description below if you want to read more about this card but the takeaway here is that overclocking at a trade show is hard thanks for watching I'll see you all next time
