GA-Source heeft een review van de Hercules 3D Prophet DDR DVI online gebracht. Het door GA-Source geteste exemplaar bleek verassend op een setting van 130/301MHz geklokt te zijn, hoger dan andere 3D Propheten die in de omloop zijn. De kloksnelheid kon middels het in de Detonator drivers ingebakken overclocking slidertje verder opgekrikt worden tot maar liefst 155/340MHz:
One thing that I was surprised by when I started to look at overclocking this board was the fact that it was default clocked at 130/301. I went and looked around the web a bit and found a couple reviews mentioning the core speed at 125 and a few others mentioned it as being 120. What this means, I don't know. I will of course update the exact specification that Guillemot ships the card at as soon as I hear from them. For the time being I will assume the default is 130/301.
[...] The SGRAM on the board was Infineon rated at 6ns. It was default clocked at 301mhz. Don't let the 6ns rating fool you, the speed of the chip is actually 150mhz times two. (DDR) At 6ns it should be able to hit 333mhz (166mhz *2) with no problems. It was able to do that and then some. The chips would run stable at 340mhz. It would run fine at 345mhz for a few minutes and then anomalies would begin to show up on the screen. The final number we are left with is 155mhz core and 340mhz memory. Not that bad of a jump over the stock speed.
