Is this a Decent Overclock

[Dyewitness]

After some trial and error. I have managed to create a stable overclock. The overclock speed is shown below. I was wondering is this a decent enough overclock speed. Idle temp is 48 and Full load temp is 63.
Ram is at 2.8V (5:4 ratio)

Or.... can i overclock more with this specific chip ?
