PowerColor Red Devil RX 580 Golden Sample Overclocking

We take the new PowerColor Red Devil RX 580 Golden Sample and overclock it as much as possible as we did not have time to do this in our original review. Find out our final overclocking results and how high the new AMD Radeon RX 580 GPU is capable of going. Will we break through past 1.5GHz on this GPU?

Introduction

On April 18th AMD debuted it’s refreshed re-branded AMD Radeon RX 500 series. We evaluated the Radeon RX 580 variety using a PowerColor Red Devil RX 580 Golden Sample video card. While this video card carries a decent factory overclock, we did not have the time to perform our own manual overclocking in the initial evaluation. This short article today will show you what our results are when manually overclocking the video card and a couple of performance measurements so you can see what the difference is. If you aren’t familiar with the Radeon RX 580 and its specifications please read our evaluation.

Here is a short re-cap of the important bits you should know about before we dive into our overclocking attempts. The reference clock speed on the AMD Radeon RX 580 is 1340MHz and 8GHz memory. Our PowerColor Red Devil RX 580 Golden Sample comes clocked at 1425MHz and 8GHz memory. That is a 85MHz overclock compared to the reference specification. If you compare it to the default clock on an AMD Radeon RX 480 this card is 159MHz faster.

One of the benefits of the Radeon RX 580 is its potential for much higher clock speeds, albeit that comes with healthy does of wattage as well. At 1425MHz the PowerColor Red Devil Golden Sample is already overclocked past the highest overclock we ever achieved on an AMD Radeon RX 480. Now we want to see if we can take it even higher, to clock speeds a Radeon RX 480 could only dream of.


Highest Overclock without Voltage Increase

We first like to begin overclocking by finding the highest GPU clock frequency we can without touching voltage. This tells us how much headroom there is on the GPU at the default voltage. Then we proceed to raise voltage and overclock for our final highest stable overclock.

PowerColor does not have its own overclocking utility, and while AMD Radeon WattMan is an option, we chose to use MSI Afterburner with its easy interface and UI. It also has the ability to display information like clock speed, voltage, temperature in-game so we can monitor those frequencies in real-time while gaming. The latest version of MSI Afterburner did work, and did allow us to increase the voltage.

In the default screenshot above you can see it starts out correctly at all the defaults. Note that the Power Limit can be increased by +50%. We can also set a manual fan speed, and for our testing today we did set a 75% fan speed to ensure temperature wasn’t holding us back. At 75% fan speed these fans are not very loud.

In the above screenshot is what we were able to get the GPU up to without touching voltage. As you can see we hit 1440MHz just fine without touching voltage and just raising the Power Limit while keeping 100% in-game stability. That is a 15MHz increase at the default voltage. Remember, the default voltage on this GPU is 1.225v. That shows that there is some headroom even at the default voltage. Of course, you all want to see what we could really push it to at the highest voltage we could set. For that, read on to the next page to see the final overclocking result.
