ahh you only hit 425mhz core?! 1.1ghz memory?! yea i guess u did get a dud with overclocking, but either way your running a fast video card, or you might want to check and see how hott your card runs. my x850xt with the stock cooler would overheat and get bad performance in games and this would be at stock clocks, but thats all changed with the cpu heatsink mounted on there with artic silver 5. i got 530mhz core with 1160mhz memory and max core is 49c.
