I suppose you are all already tired of answering the same qs over and over again but since im noob at OCing I wanted to make sure im doing the right thing.

So to the point, im trying to oc my cpu on gigabyte 990fxa ud3 rev 4.0 mbo. So far i have not reached a stable OC of 4.4 ghz or above (prime crashes after and hour and 20 min more or less). My cooler is Evo 212 and i read that it can cool the cpu to up to 4.5 which is my goal. So the solution would be to up the cpu voltage which is by default sitting at 1.284xx i think. Raising the voltage to 1.29 or 1.30 gives me the temps im not sure i should run it with. The temp goes as high as 60 Cs on Core, 59 on tempin2 and 59 on package temp monitored with speed fan and hw monitor. The cpu starts to downcloack to 1.5 ghz as soon as it reaches 60. Think package temp is socket (?) but not sure.

So my first q is can i leave the cpu to run on 60 C and see if itll fail the test? (i read somewhere that 62 is the max temp for fx 8350 so im kinda afraid to leave it there while the hw monitor and speed fan shows "code red". Ran prime on those voltages for about an hour then i stopped it. Didnt want to risk it without asking first.

Second im running rev 4 F2 version of the BIOS, there is a newer version F3 that has "updated AGESA or AEGESA code" or some such. Really dont know what that is so my q is pretty simple, should i flash my BIOS or not, i dont have any problems with the current version on stock speeds?

Thirdly im using a combination of both multiplier and fsb to reach 4.5 at first, now 4.4 ghz but both failed so my q is did i misunderstand that both fsb and multi yields better performance and better "stability" and should i try it with just multi or just fsb to try and reach better stability without upping the voltage that much?

4th should i or shouldnt i touch the nb freq which is by default 2200 when i change fsb or multi, or can i leave both nb freq and ht link (2600) on auto and just check if they are near defaults like with memory? Memory goes up from 1600 to 1700ish.

5th cpu unlock option on my bios, read it that its something about hidden cores, didnt understand that properly so if anyone can tell me should i leave this on disable or enable it? Tried both but prime crashed with both options so right now im thinking it doesnt matter.

Well since this is my first OCing i hope my qs are answered since it would help me to better understand the process and hopefully reach at least 4.4 ghz without too much voltage. (i should probably reapply thermal paste since well it could be i didnt apply it properly (too much or too little) the first time, but uh dont have time for that right now.

Apologies if i used the wrong technical term somewhere, as i stated im a newbie at this.
 
Ok so ive dwnloaded aida64 extreme so i now know what temps im running my cpu at. Played with bios (voltages, vcore loadline calibration settings (finally know wth thats for) etc) googeled the rest of my qs and it seems so far ive manage to find a first step stable oc at 4.5 ghz with core temp at 55C and north bridge temp at 54 C ( as shown by aida). 12 h of prime and no error so far, still running. Im gonna run 3dMark next.

I had to set vllc at medium so my voltages are -0.01 to -0.015 than the ones i set manually. If i set it at extreme i get +0.06 and more voltage jumps and that gets me over 60Cs in a sec.

But now i have 2 new questions that i would really need an answer so i can continue with my oc.

First one is about Prime, during stress test i noticed that cores sometimes drop to 1.5 ghz under full load but voltages stay the same and temp at the downthrottle is around 53C, 55C max. Ive read that fx 8350 downthrottles at 62, im 7 degrees below that so is this normal? Dont have any errors in prime nor warrnings.

Second since i cant put vllc on extreme or auto or any other setting other than medium (the closest i get to set voltage, idile or under load but its still in - of the one i set) can i be sure that 7C is enough if the proc decides to pull that 0.010 voltage or should i test the oc on higher voltage to see if it can handle it?
 
P.s. run 3d mark a few times all good no crashes, but ran aida stability test and i got a crash in 10 sec, running trail aida, so im guessing im still unstable?
 
Just run most demanding SW you'd ever use and don't worry about torture tests. use them only if SW/games are crashing. So many people torture test their computers to death and their SW/games crash anyway !!!
 
Ill try intel. But well the aida fail wasnt cpu related fsu ran fine. I didnt adjust ram multiplier enough. Got that fixed now, will ask you later about the ram oc. But now im again on fsu testing case i dont wanna see 1500 mhz on any test not even after an hour of test for a sec. :)
 
So at what lvl should i run ibt? High? Very high? Extreme seems a bit extreme from what little i found on the forums for this test? And for how long?
