Overclocking XFX SPEEDSTER MERC 319 RX 6700 XT BLACK

To overclock the XFX SPEEDSTER MERC 319 BLACK Radeon RX 6700 XT, we are using the latest MSI Afterburner.  XFX does not have its own overclocking software.  The version was 4.6.4 Beta 3.    

XFX SPEEDSTER MERC 319 BLACK AMD Radeon RX 6700 XT msi afterburner highest overclock

Above you can see the highest we were able to overclock on this video card.  Firstly, the Voltage was maxed out at 1200mV, this is the default, and the highest we could go; therefore, it was not possible to change the Voltage.  However, what was impressive was that we could bump the Power Limit up +15%.  This is higher than the MSI Radeon RX 6700 XT GAMING X which was restricted to +10%.  That extra 5% did make a difference for us. 

Another feature that was locked though was the memory, the maximum it could go up to was 2150MHz, this is the same on the reference video card, and the MSI.  It seems AMD does not want you to go higher on memory, even though it could probably overclock higher than this. 

Overall, then, we were able to push the Core Clock setting up to 2890MHz.  Now, this doesn’t mean the frequency ran at 2890MHz, it basically just gives the GPU permission to run higher if it can, and the further you push it up it gives it more headroom to increase.  To see what the actual frequency was when overclocked, look at the graph below.

Highest Overclocked GPU Frequency

We will now graph out the overclock of the GPU playing Cyberpunk 2077 at “Ultra” settings in a manual run-through. 

XFX SPEEDSTER MERC 319 BLACK AMD Radeon RX 6700 XT overclocked gpu frequency comparison graph

This graph shows our overclock compared to the default frequency.  Remember, the default frequency averaged 2576MHz for us.  Well, this overclock, with the setting at 2890MHz, allows the frequency to hit around 2788MHz, in that range.  The average is actually 2787MHz.  At 2787MHz this overclock provided a 211MHz average frequency overclock, or 8% higher GPU frequency.

This is the highest overclock we’ve seen to date on a Radeon RX 6700 XT video card.  The MSI Radeon RX 6700 XT GAMING X overclocked to 2737MHz average.  Therefore, the XFX MERC 319 overclocks higher at an average of 2787MHz.  That’s a 50MHz higher overclock.  It is also much higher than the reference card which overclocked to an average of 2717MHz.

GPUz Sensor Data Overclocked

Overclocked at 100% fan speed the maximum GPU clock it hit briefly was 2804MHz.  The GPU Temperature was 47c and the GPU Temperature Hot Spot was 68c.  These are incredibly good temperatures, but the fans are at 100%.  The GPU Voltage was the default 1.200V.
