uhm... for starter u can try to leave the memory timing at auto, set mem voltage to 1.65v and see if its ok with that oced speed.

open up cpuz and check the vcore voltage, see what is the vcore and then try to set it in bios to make it about the same as the one showing in cpuz, reboot and then open cpuz see if the new vcore setting u set matches the one u check at the 1st time, this is to let u set the vcore manually and u know what is the baseline of it being set to auto and it ran stable with the stress test, from here on you can play around with the vcore in bios plus or minus, this would help u to oc further if u know the baseline of the vcore, this is for cpu overclocking. essentially u can lower down the vcore 1 step than the baseline, it might still stable and u will have less issue by lower it down.

for mem overclocking, 1.65v will be my baseline and it was mention by intel as well. max you can set should be 1.7v, put a fan on the ram, it would help a bit too. if 1.65v ran fine with the overclocked settings, then leave it as it is, dont add more voltage unless u wan to get higher speed but u will have the risk of killing the hardwares since you are new into this.

i hope you understand what i am saying here, else u can just pm me and shoot me with related questions, i will try to assist you from there

just becareful with the voltage u set, dont over-set it

set vcore to 1.3v and try to stress test it again

u are setting ur vcore as 1.87v now?? after lower it down lol.... try set to 1.3 and stress test again with the same cpu speed, if its passed the test then set the vcore 1 step lower than 1.3v then redo it, to find the lowest vcore it can get with that speed

advisable use a 3rd party cooler when u oc, heat is the biggest enemy in oc =)
also put a fan on top of ur ram to ocol them down

yes, if u are ok with 3.6ghz then its time to find the lowest vcore for 3.6ghz. after it is done, then its time for memory if u wan

it might be slightly different sometime, i dont know how to explain this but well... just set vcore as long as u can to get it stable.

well its actually helps in maintaining the vdroop, u try to open a cpuz and observe the vcore during idle, then u try to run stress test, the vcore value shd change, thats called as vdroop, load line calibration enable will set that as fixed =)
