Well,after some gaming,it was't stable at all.
Pubg tends to find unstable oc easily and crashes.And other things crash when that happens which makes me think it's the ram,but I seriously can't find the cause of instability.
As I said ,my settings for the past two years which were 100% stable were 1.21 Vcore,1.06 Cache and +0.06 offset for SA.Now I have tried up to 1.22 Vcore,1.12 Cache,+0,1 SA and 0,05 Digital and analog offset.I haven't messed with Vrrin,because at load is at 1,69 which is over the 0,4V that it requires from the vcore.
When I oc only the core and cache,it's stable.I'm checking it with Prime95,which at 95% of the situations if I get past the 2 hours then I'm stable.When Ram gets into the game,then it's not.
It's quite hot here there days,but it had been the past years too and it worked just fine with no problems.
