Overclocking FX-8150 on Fatal1ty 990fx [HELP!!]

post #1 of 14
Thread Starter 
Okay, so its finally the time for me to ask for help overclocking my 8150 after only getting BSoD and freezes im tired of trying doing this on my own.

I have looked at several overclocking guides also the ones about Bulldozer OC... I've read the mobo is not bad at OC but I dont see any other things that makes me fail so hard

Most important specs (check rig, is something more is missing) :

FX-8150
Fatal1ty 990FX professional
Chieftec nitro 1200w
XSPC Raystorm 750 RS240 (WC)

I have disabled everything in the advanced cpu mode and changed the multiplier and volt only.

I can run a prime95 stress test on 4.4Ghz with 1.450V and my pc will freeze almost instantly, and it pisses me off.
I have a goal getting it stable at 4.8Ghz but hows that possible when it cant even run stable at 4.4..?

Any help would be much appreciated redface.gif

What is your LLC setting, is the vcore dropping to low when you put it under stress ?

If the computer freezes you need to add more voltage until its stable.
Not every chip is stable at 4.5Ghz 1.32457V
Instance my i7 runs 4.7Ghz @ 1.4V whilst other CPUs can get it stable at 1.3V

I am not so good with LLC but its on Auto or something.
I just took some pictures of my current settings

(Just click if the pics are too small)

I looked at the Vcore when stress testing and yeah it actually dropped..

Edit : Apparently so did the Ghz.. -.-

Before stress test :

It looks like you might be having the same problem I had with my ASRock 990fx board, which I asked about here: http://www.overclock.net/t/1316561/overclocking-fx-8120-to-4-4ghz-problems-cpu-or-mobo/10#post_18393713

It ended up being that vdroop (difference in voltage with load and no load) was causing the problem. Try setting your LLC to 1/4, this worked for me, or even disable.

it shouldnt drop your clock speed under load, so in reality you would be overclocking for nothing. try to disable turbo. "overclock mode"- im not sure what that is but maybe should be put on manual. im not exactly sure what cpu active core is but im guessing you can shut down cores with it. set that to all cores or whatever setting will make sure to use them all. you can disable spread spectrum. put the LLC on the highest or second to highest setting. so that the vcore will increase or stay steady, not drop under load.

You have to increase the LLC, to stop the vdroop (that's why your insta-crashing under load).

As it was said above, 1-4 would be enough, to keep the voltage from dropping massively (1.376v to 1.208v? LOL STABILITY, NOPE.)
