![]() ![]() But if you have one of the best graphics cards and you're looking to eke out a bit more performance, we'll discuss how we go about overclocking and determining "safe" settings.īefore overclocking, it's useful to get a baseline measurement of how your graphics card performs. Of course, as with any overclocking, care should be taken to avoid running your GPU at unsafe settings. Let's wrap up, and you can also watch the bossman talking you through this.Overclocking your graphics card can improve its performance by 5% to as much as 15% (or more), depending on the particular card model. In this particular instance anything above these figures hit a wall, so going further without investing in liquid cooling is outside of sanity. Only add volts once you've hit the clock cliff, or if your maximum speed remains high but the average drops like a stone. These are the bits you need to pay attention to. Naturally we've given you the key moments, so it looks like we blundered through a bit, but we wanted to show the big steps and trust to your intelligence to extrapolate the middle bits. Lastly another 25 Mhz, just to smooth things out, gives us our final figure. 200 MHz to begin with, as it's less sensitive than the core. Keeping the GPU clock and voltage the same, it's time to add a bit more speed to the GDDR6X. Maximum boost is all well and good but, as we have said throughout this, average clock speed is what gives better results. So the sweet spot is somewhere between these two attempts.īacking off on the voltage and core speed we return back to where we were, but more stably and with a better average clock speed. Greedy from the previous result we added a little core voltage to help push another 25 MHz (175 MHz total) and our Time Spy score went down to 16472. This is what we mean when we talk about cliffs and dropping off them. A nice start.Īdding another 50 MHz on top of that really unlocks things, seeing the score jump another 229 points to 16559. With a 100 MHz core clock boost, we get 16330. We've temperature limited our card, for obvious reasons even in the depths of a British Winter. It's very easy to get greedy and go over the top. ![]() With Time Spy Extreme to run we can test how good our OC is, and how stable it is. We don't want anything hindering our efforts, even if we're not utilising it all. Softly softly catchy monkey.įirst up we're just whacking the power limit right up. ![]() Don't take these numbers as gospel, take the method and apply it in a manner that lets you feel safe and keeps the magic blue smoke in your card. Secondly, and most importantly, these are the settings for our card. This side of water, just tolerate your fans doing their best. The RTX 4090 is the exact type of card that will annihilate anything you attach to it on air, even the excellent MSI Suprim cooler. Firstly you have to just accept that your fans will be running their nadgers off. As we'll reiterate in our wrap-up, there are a few key things to remember. It currently opens showing 93% power, so hit reset to get the full power - as you saw on our first page - and then get down to business. Obviously the first thing you'll need for an overclock is the famous MSI Afterburner utility. ![]()
