How to Find Graphics Card with Higher Overclocking Potential?

Graphics card overclocking is a process of increasing the frequencies of GPU and Video Memory to enhance graphics card performance. Overclocking is not for everyone as it is a bit of risky process and it can void the warranty of your graphics card. But on the positive side it can really boost your graphics card performance to up to 15% to 20% or may be even more depending on the amount of overclock and graphics card capability.

Each graphics card has its own overclocking potential and beyond it would fail and may get damaged or burnt. Even graphics cards with same GPU from different manufacturers have different overclocking potential. This is because of the various factors that I am going to explain below and also tell you on how you can choose the best graphics card having greatest overclocking potential.

What to Look for in a Graphics Card for Overclocking?

Here are the most important things that you have to look for when you want to buy a graphics card with higher overclocking capability. These tips apply to both Nvidia and AMD graphics cards.

Cooling Solution / Cooler

When you overclock a graphics card then the temperature of its major components i.e. GPU, VRAM and VRM (Voltage regulator module) rises to great amount. So if you are planning to buy a graphics card with good overclocking capability then you have to look for a graphics card with a good cooler having two or three fans and heatsink equipped with heat pipes and copper plates. If you really want to go pro then you can buy a graphics card with liquid or water cooling solution having hybrid cooler or water block cooler. You can read more about the various types of graphics card cooling solution by going to the link given below.

Better Cooler = Lower Temperature + Higher Overclocking

So if your graphics card cooling is good then you can push your graphics card GPU to much higher frequencies and get the more performance out of it. You can also overclock the video memory of your graphics card but generally it does not have that much effect on the performance of graphics card compared to GPU overclocking.

Power Phase

Power Phase is also an important factor that governs the overclocking potential and stability of graphics card. It is a very technical term and may be hard to understand for some users, but here i am going to explain it in the easiest manner. AC Current travel in form of sine waves and the difference between each sine wave is known as phase. A single phase system has only one sine wave and it has phase difference of 360 degrees whereas a three phase system or power supply has three sine waves and the difference between two peaks is 120 degrees or they are separated by an angle of 120 degrees each. This results in cleaner power, stable voltages and better load carrying capacity. So a graphics card with more phases means it has more VRMs (Voltage Regulator Modules) and thus can be overclocked to higher frequencies without putting load on the transistors and VRMs. With more phases you can push more voltage to GPU for higher clocking without worrying too much about the stability of the graphics card and temperature of the VRMs. Graphics Cards with more power phases tends to be expensive compared to the graphics cards with lesser power phases. Below you can see a three phase power system.

More Power Phases = Better Stability during Overclocking + Higher Overclocking + Constant Power Delivery + More Stable Voltage + Less Ripple and Jitters

Power Phases for graphics cards are expressed as X + Y notation. Here X is the power phases for GPU and Y corresponds to the power phases for memory or memory controller. For example a graphics card having 8 + 2 Power Phases means it has 8 power phases for GPU and 2 power phases for VRAM or Video Memory. So a graphics card with 12+2 power phase will have higher and stable overclock compared to graphics card with 7+2 power phase, even with graphics cards having same GPU and memory configuration.

Advantages of More Power Phases

  • Better and stable power delivery
  • Much Stable voltages
  • Less Ripples and Jitters
  • Lesser load on VRMs (also lower temperatures)
  • More Overclocking Potential
  • Higher current carrying capability
  • Higher overall efficiency
