Last try i made, 1075mv, uped the core target to 1650, now i get around 1600MHz 66-67ºC. Passed a 3dmark stress test. 1075mv core target 1650. Spoiler I dont get this, now with a Firestrike extreme test. Why cant clock stay at 1600? Same config as above. Started around 1400-1500, maxed at 1600 second test for some time, then back to the 1550. edit: Could be the power target? Got it at 25%... ill try with 50%. Spoiler Yep, it was de power target. Spoiler Dont know if its worth the 50% power. W tops at 250 for the first test. Where is the sweet spot? What would you do?
