Modern computers have hardware that seems to increase at least some of their performance values with each new version that every manufacturer puts out. Even with what seem to be exponential increases in potential or power, some computer users are still looking to push the limits of what their devices can do.
This is where overclocking comes in, and you can do this even without in-depth knowledge of technology. Overclocking involves getting certain components inside your rig to run at faster or higher speeds than the maximums for which they are rated.
In our article, we will discuss whether overclocking something like VRAM can make a difference in how your computer runs certain programs. Further, we’ll talk about the higher FPS potential, if any possible damage to the VRAM could occur from doing this, and whether the heat the memory gives off could also increase.
Your computer’s VRAM is its video random-access memory. If your device has a dedicated graphics processor, it should have some VRAM in order to help it perform its tasks. This memory is specific to the GPU, and it should not be confused with your system’s regular random-access memory, or RAM.
Your computer will access these two memory types in different ways, but the main thing to keep in mind is that VRAM is for storing data related to graphics and visuals. It is what helps your games or other graphic-heavy applications load complex, three-dimensional models or textures with ease.
Your graphics processor may borrow some system RAM as well, but we’ll cover just what the video random-access memory is capable of here, for the most part. If you want to overclock VRAM, you’ll ask it to run at higher speeds than it would ordinarily do, and this means storing or accessing data faster than you might be used to.
You can think of it as giving the memory more power to perform its tasks faster or better. Therefore, overclocking VRAM can make a difference. However, in order to be noticeable, this difference might be dependent on a couple of things.
Mainly, it can depend on the load your graphics processor is under before overclocking occurs. To get the most out of overclocking, your GPU would need to be running at a full load already. This benchmark would mean that increasing the VRAM beyond how it normally runs could help the GPU perform better operations even under a full load. It is possible that the difference won’t be as noticeable to you if your GPU isn’t already operating at full capacity.
Some users may notice low performance when it comes to games, and their immediate reaction may be to increase VRAM to overclocking speeds in order to compensate for that. While this makes sense, it may not address the issue at its source. If you are experiencing what might be performance-related issues while running something like a game on high-end specs, check the GPU’s percentage load first.
There are programs you can download and run to keep track of these numbers. If you notice that the graphics processor is only operating at around half of its full load with performance issues still present, this could point to a problem with the central processing unit instead.
Even though your graphics processor is a big help when it comes to games, your central processor still plays a vital role in all of your computer’s operations. In some cases, you might upgrade your graphics processor without touching the main one.
When this happens, your GPU then outclasses your CPU. This is one of the cases in which CPU bottlenecking might occur. If you’re running a game that is quite demanding, the overall performance of your computer across multiple areas could start to stall. When this happens, you’ll notice sluggish response times, drops in frames for the game itself, graphics issues, and other problems.
If your central processor slows down, your graphics processor can feel some of those effects, too. It is a separate unit, but it still relies on communication with the CPU to help it perform all of its duties. As a result, you may notice subpar performance with anything having to do with the graphics processing unit. However, it is important to note that some bottlenecking between these two components is normal.
It’s not possible to have absolutely perfect synchronicity between the CPU and the GPU. The key is to make this lack of connectedness as small as possible. Closing background applications or increasing a game’s resolution are two ways you might take some stress away from an overworked central processor.
The FPS is a measure of how many frames per second a game can render the images on your computer’s screen. The higher this measure is, the more smoothly a display can show you images running back-to-back.
That means that a good FPS range makes games or videos look cleaner, with minimal choppiness or tearing that could take you out of the experience. Some users like to overclock their VRAM specifically to see if it can have a positive impact on the frames their games can display each second.
Yes, overclocking the VRAM should increase the FPS rate. This may not be true in all cases, but there should be a noticeable increase in many of them.
If your game is already running quite smoothly even on high recommended specifications, you may not be able to tell the difference once you overclock the VRAM. However, this can depend on the specs for the rest of your system. It can also depend on just what kinds of graphics, textures, or models a particular game renders.
The other thing to note is error correction. Even if you can overclock your VRAM to very high levels, there is a point at which it will plateau. Once it does, the gains you’ll get in game performance will be negligible, and you may not notice them at all. Furthermore, the overclocking may go so high that framerates and other aspects of video quality begin to suffer.
When these things happen, it is usually because the VRAM is working so hard that errors are introduced into the system. There are error correction protocols that try to fix this, but they can result in decidedly worse graphical quality, even though that seems counterintuitive. If you’re going to overclock your VRAM, check to see if there are any recommendations for your specific make and model.
Most VRAM memory should be rated to run at somewhat higher than its maximum recommended speed without taking any damage. Usually, a manufacturer will make this decision as a way to keep the VRAM running at a stable rate under a heavy load.
However, anything that is pushed too far beyond its maximum limits for too long can find itself damaged, and this is particularly true for technology.
Overclocking VRAM requires that higher voltages run through it continuously. If the voltage stays too high for too long, you may find that it is too much for the VRAM to handle. Some of the parts through which the current passes may take some damage.
This could be negligible, but it could also be enough that the memory has trouble functioning adequately. To test for this, you may want to dial the overclocking back in increments of 50 or so Mhz. If the VRAM seems more stable and stays that way, you should be fine. This is also a good way to test the upper limits of its overclocking capabilities in general.
Yes, in most cases, overclocking the VRAM should raise its temperature output. It is running at faster speeds and takes on more voltage.
Both of these things increase how much power is needed for the video random-access memory to function, and that means an increase in how warm it gets when it is operating. In short, more friction equals more heat coming off the component.
The specifics of VRAM temperatures can vary slightly from one manufacturer or model to the next. However, most companies try to create video random-access memory that is able to run at temps close to 90 or 100 Celsius. That doesn’t necessarily mean that you should run your VRAM at the upper range of these temperatures continuously, however, running hot for long periods of time can shorten the overall lifespan of the memory.
If it is running at temperatures that are close to or over this limit, it is probably too high for continuous, resource-intensive operations. You may see a dip in performance if this goes on for too long.
However, you should still be able to overclock your VRAM and run it at comfortable temps. Thanks to the graphics processor’s own cooler, which is often close to the VRAM, the chips should be able to run at decent temperatures. Further, you might have memory that features cooling pads connecting it to the GPU cooler, too.
Overclocking VRAM just requires a few tweaks, and it can be a good way to squeeze more performance out of your GPU and its memory. This increase can result in smoother gameplay or textures at higher resolutions.
There is an upper limit for this, and there will be diminishing returns if the overclock gets too high. There are also some risks in damaging the VRAM or making it too hot, so be sure to follow any overclock recommendations for the memory you have in your system.
