The same 3d scene was rendered after overclocking the CPU to almost 4.9Ghz, and I could see and hear, all the fans spinning at top speed, and my liquid cooler is pushing it’s limits, as the CPU ran hotter. CPU runs at 4.4Ghz without any overclock settings and completed the render in 2 minutes and 32 seconds.
This is a basic rendering test, where a 3d car model is rendered with Vray materials, like car paint, ray-traced glass, and HDRI used for lighting the scene. The graphics card that I have is a basic level gaming card which gives 45-50 fps with graphics settings set to extreme at the resolution of 1024×768 pixels in Crysis 2, and with Ultra settings, frame rates drop below 30 and becomes choppy.ģd rendering with and without overclocking.ĬPU speed without tuning or any overclock settings. The board I own is MSI Z97 pcmate, which has settings for overclocking in the bios, and I used Intel Xtreme Tuning Utility as well, and my CPU i7-4790k is an unlocked processor that runs at 4GHz base clock, and 4.4GHz Turbo Boost Mode, and you can still overclock it with an excellent cooler, as this CPU will turbo boost as long as thermal headroom is available. First I will brief out the hardware, apps used and experiments done with overclocking.Īpps used – Intel XTU, CPU-Z, Realtemp, 3ds max and Crysis 2Įxperiments – 3d Rendering and Crysis 2 Gameplay FPS. Here is my experience on overclocking a CPU and how much of performance I really gained out of it. In my case, as I said, I caught wind of it and got carried away. But in the end it boils down to one thing, personal preference. Many will say that you won’t get a direct answer, or there are over thousand answers for it. Ok, that being said let’s dive into the obvious question. But remember, overclocking produces a lot of heat, and you must have an excellent cooler to protect your CPU from being fried, you also need to consider the ambient room temperature, a factor that directly impacts the performance of your CPU cooler. Well lets see how fast an overclocked CPU will perform.
The process of increasing a component’s clock rate, eventually to make it run at a higher speed than it was originally designed or intended to run, which is usually done with CPU or GPU, so that the CPU or GPU perform more operations per second. The debate would be about the advantages and disadvantages of water cooling the processor and running it at 10.4 Ghz, seriously?
There will be a debate on overclocking even if we are likely to have a 10 GHz processor in future. Oh yes, I said it, yes, there is much debate in regard to Overclocking a CPU on every tech forums, and it will go on for ages. CPU Overclocking is almost like a highly infectious disease nowadays, and I suffered from it for a brief period of time, and recovered from it before crossing the extreme levels of insanity.
