Hi, this is my first post on this forum. A little history: I've bought my RX590 a couple of months ago, problems started right away with games crashing and high temperatures, but since returning policies in my country require some vendor RMA and it will do some benchmarking, in which the GPU behaves like a princess, no good would come my way. So, I've done multiple testing, read lots and lots of forums and nothing could tame the beast, until a couple of days ago when I turned power to -50%, then it was awesomely stable, I ran it for a day with some 1440p Forza Horizon 4 and Gears 5 in Ultra. No crashing, no nothing, but, obviously the card is so calm that it bothers me. So I started to go back little by little until I found the card is stable and regained most of its spice (those beautiful high pitch capacitors) at -15%. The thing is, it still bothers me I'm losing some performance, which, I must say, it's not a lot, at stock power the card gives me 3 or 4 more fps, which will change nothing. But, I've paid for that extra 15% and I intend to use it. I've used AIDA64 to monitor the 12V rail, and it never goes under 11.8, I know this is something that comes into everyone's mind while reading all this power related stuff. So, if anyone has some insights or ideas I'll welcome them and try them. Specs: I7 7440k (20% OC by Gigabyte BIOS grace) 12GB Ram (3 2400mhz Gskill Sticks) PSU is an XFX XTR 750 80+ Gold The story is longer, but I didn't want to bore anyone more than they probably are.
