Overclocking software One-click overclocking If you really want to take any of the tinkering and most of the fun out of overclocking your Nvidia GPU, you can instead opt for Nvidia’s Scanner functionality. Leaving only memory clocks down to the user. That ought to either flag up any gremlins lurking in your system or help get rid of them before they become an issue.
Next, grab some overclocking software. As well as the software for enacting any overclock you want to achieve you should get yourself some benchmarking applications too. I suggest downloading the Unigine Heaven benchmark. And it looks kinda purty, too… 2. Benchmark baseline performance You need to get some baseline performance numbers for how your rig currently performs.
You could also download the free version of 3DMark and run the basic FireStrike test to get a reliable index score. Time for an upgrade: On a native p screen, run it at x , and then, with a p or 4K panel, run the test at x We cannot stress this enough: Start shifting the memory slider to the right in MHz increments, hitting the tick button to apply the boost each time.
After each step, check the looping Heaven run for visual artefacts appearing on-screen. Memory glitches will manifest themselves as either solid blocks, blobs of colour, or pin-sharp stars. Keep pushing the memory slider up in small increments until you start to see those telltale signs of failing memory… or until the card or system crashes.
Once you get to that stage, dial back the clockspeed by either one or two steps, apply the new memory clock, and leave Heaven running for a longer period to make sure it remains stable at the new speed. If you see more memory artifacts, drop down another MHz increment, and test again.
Before you start upping the GPU clockspeed, push the power limit slider up to max — allowing the graphics card to deliver more power to the silicon if it can — and also push up the temperature limit a little higher to account for the increased heat generation.
Using the same process we used when overclocking the video memory, push the GPU clockspeed up by MHz increments, checking the game window for artefacts as you apply each step change. Processor artefacts manifest themselves in different ways to memory issues. Keep an eye out for pixel-sized dots of different colours appearing around the screen, random shards of colour, or bright and coloured full-screen flashes. The full GPU overclocking package Now you want to see how everything looks with both the GPU and memory clocks set to the peak levels you discovered individually.
If you get a system crash, on the other hand, simply reboot and set both memory and processors speeds back one step, and test again. Test and test again Close down Heaven in windowed form and restart it fullscreen at your native resolution and leave it looping for a good ten minutes to make sure it remains fully stable at your new clocks. When you are positive it is stable, hit F9 to benchmark, and see what performance increase your efforts have afforded you.
You cannot be guaranteed of a particular overclock or indeed any overclock at all as every GPU will have a different limit because of vagaries in the manufacturing process. You might get lucky and find your GPU will boost like a beast. Similarly, you might not be able to get much extra performance at all. But as certain accidental horse-meat suppliers are wont to say: There are other things you can do to help, however. If your card is a reference version, using either a standard Nvidia or AMD cooler design, you can buy relatively cheap third-party coolers to replace them and potentially deliver higher overclocking performance.
The overclocking process is similar to the one I detailed earlier — patiently pushing up clockspeeds while checking Heaven in a separate window — but there are a few, slightly different steps. First you need to raise the minimum and target fan speeds, then switch from auto to manual and increase the temperature targets.
How to overclock — CPU 1. Prep work Overclocking your processor is a slightly different bag of chips to boosting the performance of your GPU. Though the basic principles remain the same: Not every processor can be overclocked these days. Intel put the brakes on that a while back by locking down the clockspeed multipliers on all but their most expensive SKUs.
You need to make sure your CPU has an unlocked multiplier to be able to get serious performance boosts. Check out our guide to the best CPUs for gaming for our take on the top processors around right now. They just happen to also be the ones that are most comfortable with having the clocks tweaked, too… Read more: Though you will have greater access to the different settings of your AM4 board going through the BIOS rather than the more basic software.
Stay fresh, stay frosty Once again, you need to make sure your PC is fully up to date. The manufacturer and model of your board will be listed in the window that pops up, as well as what BIOS version is currently installed. Chances are the BIOS will reject it. But, at worst, it could brick your motherboard completely. You may also find your BIOS has a handy auto-overclocking function — many of the modern boards will come with such features. The BCLK will likely be set at MHz by default, so for a Core i5 K, for example, the multiplier will be set at 35 out of the box producing a final clockspeed of 3.
You should then see a calculation of the final clockspeed somewhere on the page. Then save the settings and restart your machine, booting into Windows.
Then, if everything works as it should, reboot into the BIOS and rinse and repeat until either the machine refuses to boot why, hello Mrs. Bluescreen of Death, how nice to see you… or it falls over part way through your stability benchmark. When that happens, simply reboot into your BIOS again to change the settings. From here, knock the multiplier down by one, save, and reboot testing for stability in Windows.
You may need to delve into your machine and get a look at your motherboard, though. The method can differ from manufacturer to manufacturer — Google is your friend here. Prime95 is a great stress-testing tool for CPUs — if your overclock can survive ten minutes running Prime95, chances are your new clockspeed is pretty damn solid.
Now you should have a rock-solid CPU overclock, hopefully at least boosting the minimum frame rates in-game, and potentially freeing up a little extra performance from your graphics cards as a whole. There must be more to it than that…. Of course there is. Get up to your elbow in CPU overclocking and you can start messing around with the voltages and baseclock settings, but that way lies greater long-term risk to your hardware, and a lot more intricate fiddling in various BIOS settings, too.
Besides, fiddling with voltages also increases the heat output and may only get you a little higher clockspeed. You can also increase the BCLK of some processors but doing that is more prone to failure. You can improve the cooling of your CPU and your PC as a whole, which may help net you a higher final clockspeed. A good third-party cooler can be surprisingly cheap and can help improve overclocking scores by a long way, as well as ensure that an overclocked CPU keeps on trucking without falling over a little while down the line.
