MSI GTX 1080 w/ Custom VBIOS, PCB, & 10-Phase VRM

2016-05-30
Aaron we're at day one of Computex for our trip and we're looking at some of the new msi products including the new GT X 1080 with the twin rows or six cooler so this is a bit different than the founders Edition that we reviewed previously and the main differences are going to be for power and thermals and that's relevant for all the overclocking so we talked pretty heavily about overclocking when we did our GT X 1080 hybrid mod as you all saw and this will resolve some of those thermal issues so the main thing to look at is the twin froze or six cooler so it's got a double ball bearing fan design with a torx 2.0 fan and this is a updated version of the torques fan that Emma size used on previous twin Fraser models the main update is there are two types of fan blades one is a dispersion fan blade and one is a traditional fan blade so the dispersion fan will help generate a turbulence that the traditional fan can force through the heatsink and cool down the GPU itself the GPU itself should run about 20% cooler we haven't tested this ourselves but we will soon should be about 20% cooler that will help with some of the thermal Headroom issues where we were hitting 82 Celsius on our overclocks and causing really crazy spikes on the frequency so in theory that helps with that with regard to overclocking specifically the things that I'm most interested in are of course there's an extra power header you may have already seen that is an extra six pin so there's an eight pin and a six pin the total power allowance is now upwards of 300 watts the extra six pin about a 75 watt add there but you start running into the BIOS and voltage limitations on your overclock as we saw with a 1080 hybrid mod so to get around that there is a custom v bios on this we don't know a whole lot about it yet it should have some extra millivolt milli volts for the over voltage when you're doing your profiles but we don't know how much so hopefully it'll push beyond the 10 61 millivolt limit that we were running into on the founders edition if it even pushes the 1080 or a little higher 1100 that should be enough to get a good maybe hundred megahertz extra clock if it is actually unlocked in that regard so that's a big thing power phase is another big thing the VRM is now at n + 1 phase v RM and that's against the 5 + 1 phase on the founders Edition card pretty massive difference there in terms of voltage cleanliness so to speak outside of the power phasing the PCB itself is custom so this is not a reference piece B or founders Edition PCB is a custom PCB and it's a ten layer one which doesn't give some extra stability and overclock in performance then the reference design there's a backplate of course for your structural integrity but that pretty much wraps up most of the new Twin Frozr models you'll find additional information linked in our article in the description below and yeah stay tuned for the Computex coverage will have some x99 motherboard stuff coming up shortly and then other AIB partner video cards as well for the 1080 and maybe the 1070 so as always thank you for watching subscribe to watch more or if you just want to see me sweat over here in Taipei because it's crazy hot but I'll see you all next time
