VIDEOCARD OVERCLOCKING
With a stock value of 850Mhz core and 1200Mhz memory set, I tried to push the card to its 100% stable ceiling. Through several hours of testing and benchmarking, I finally found a 100% stable overclock of 950Mhz core and 1435Mhz memory which resulted in an astounding 100Mhz core and 235Mhz DDR5 overclock. That is nothing less than spectacular for a stock cooled card that only went up to maybe 57c during load testing. This should result in some excellent performance improvement over the stock results which you will see in the upcoming benchmarking section.
