now I spent a fair amount of time with the latest version of afterburner and I just want to oh okay that won't work well with the GTX 590 the the latest beta version of afterburner I was able to get my hands on does support over volting and I wanted to test my hypothesis that the under clocked gf1 tens on here the under clocked under voltage EF 110 s would be able to clock up nearer to their single card brethren like the GTX 580 if they were over volted or even Volta or even set to the same voltage as the GTX 580 so while I was not able to get to the same performance level at the same voltage with more voltage so I actually maxed out the slider and after burn I'll show you guys the settings afterwards I was able to achieve better than stop clocks of a GTX 580 on the GTX 590 when you consider how much lower clocked it comes by default I was able to get over 800 megahertz on the core which is about a 30 percent overclock which is outstanding and then on the memory I was able to get up over 2.1 gigahertz so that is about 22 percent on the memory so that's going to turn into some serious performance improvement so what I'm going to do is or what I'm doing here is I'm gonna be running a 3d mark 11 before and after to give you guys a rough ballpark of how much extra performance were able to get out of the GTX 590 by overclocking it as such now I won't make any claims about how long your card is going to last and do bear in mind guys that yeah sorry my light hasn't been pointed in the right direction here do bear in mind guys that depending on the manufacturer of your GTX 590 you may not necessarily have any warranty left as soon as you start over volting and overclocking and stuff like that so be very careful I mean this card has no warranty anyway so I'm not that worried about it so anyway yeah I'll be back when I have the results all right so here's my final 3d mark 11 score I'm using the extreme preset on the overclocked GTX 590 now bear in mind guys okay check this out temperatures even in a benchmark so we're not even talking when I'm intentionally stressing the temps are up to 86 degrees so max temps and max power consumption I'll show you guys the power consumption numbers in a bit here are significantly up versus the stock card so here are the clocks that I finalize done what just got to get it to focus okay there we go nope okay let's try this yeah yeah there we go all right it's a core voltage I have maxed out the slider that is as much as afterburner is going to allow us to give it core clock we're up at 809 megahertz so that's well over a stock GTX 580 and the shader is correspondingly high memory clock were up over 2.1 gigahertz on the memory and the fan speed I have left at Auto so I'm gonna run the stock benchmark now cuz I didn't actually do any 3dmark testing for my reviews and then I will be able to give you guys even more details so with our stock clocks we get just over 3000 3d marks so that gives us a yeah I guess it's not that much of an improvement so I guess Nvidia knew what they were doing when they clocked this card at what they did because I'm about to show you guys well first of all here you can see that the temperatures are much lower so in this benchmark we peak at about 75 degrees so I'll show you guys what I run into in terms of power consumption and acoustics so there you have it guys we can easily pull over 500 watts from the wall I've seen it peak higher than that in games like metro 2033 up as high as around 550 to 570 watts from the wall with the GTX 590 overclocked the way it is one thing to note actually is that in Metro 2033 I saw a bigger performance and than I did in 3d mark in 3d mark 11 I went from what was it a long about the numbers here beside me yeah 3d mark 11 I saw like less than 10 percent performance improvement but in Metro 2033 it was closer to 15 percent so I'm not really sure what's up with that but those were sort of informal testing numbers so I don't but - too much stock in them as far as max temps go it looks like this is pretty similar to what we saw before so about 88 degrees is as high as it goes and since it can't focus with anything there we go 88 degrees is about as high as we see it go but it is significantly louder so I'll throw a couple audio clips onto the end of this one where I'll show the non overclocked versus the overclocked to GTX 590 thank you for checking out my little video here on the limits of the GTX 590 in terms of overclocking don't forget to subscribe to Lynas tech tips from on boxing's reviews and other computer videos
