Can you send a screenshot url here because from the numbers you have given I think your gpu is running at more than specified clock speeds.
The maximum boost speed allowed in OC mode for your graphics card is 1493 MHz and also memory clock speed allowed is 7008 MHz.

Since you mentioned your graphics card clock speed and memory clock (which is a bit high for normal range), by taking it into consideration I suggest you shouldn't overclock it as it is looking overclocked already.
Also for your graphics card temperatures check this link
