Yes, if you go above the volatge you are using to get a given clockspeed stable at full load, I believe you will need a water cooling solution. An H-100 is the minimum place to start.
Just my opinion based on my experiences smile.gif

I have overclock profiles in my BIOS, one for AVX stable (1.55v at 4.9ghz) and one for Windows/gaming stable (5ghz+). I haven't had any issues with 5ghz+ crashing, but using AVX instructions in Gentoo while being not AVX stable has created a lot of odd issues that I've slowly had to work out by recompiling everything at more stable settings. I recall it only actually hard locking once but I used to get lots of really crazy things like window contents not updating, transparent oxygen theme crashing KDE, and just nasty stuff.

I think all Bulldozer derivatives chug out wrong answers for some things while not crashing under extreme overclocks as a side effect of being low IPC high frequency designs. I have noticed that Intel loves to just hit a brick wall and hard lock or BSOD. But bdverX can just chug out NAN in linpack all day long and be stable.

I don't know how. Maybe it's designed so stack pointer and program counter registers aren't corrupted very easily and on Intel those are one of the first things to get corrupted which causes reading from instructions at goofy addresses which aren't actually instructions but just garbage which makes the CPU go "OH NO!" and crash.

im not as concerened for hitting AVX stable tahts why im really only hitting it on standard i just like sing the gflops high tongue.gif but because I did an FSB OC as opposed to Multi OC im getting strange reactions when I boost my graphics cards.. either the driver fails or I get a BSOD... i think the FSB is affecting my PCIe traffic....

Ouch, that sounds like a trip to corrupting your hard drive too.

Is your PCIe manually set to 100?
How high was your FSB? I've seen those issues sometimes between 290-300+. (Increasing the CPU VDDA seems to help with this)

Maybe your Hyper Transport Link is too high?

I do like using the FSB for AVX IBT becaues it makes the GFlop's really high, compared to just Multi.

i have my PCIe set to 130 which could also be the case.. it maybe also cause im running beta drivers My fsb is 252 HT is somewhere close to 3000 can't remember right now

really i have come to the conclusion that my chip has a huge overhead of performance and im trying to adjust my system to sync with it..

I should add that it only happens when I ramp my vid cards to 900mhz which when im not OC'd i can do..

EDIT: Also, could you recommend me a mobo under 100$ in amazon (can only purchase from there)?. I'm deciding between the GA-970A-D3 and the M5A97 R2.0, not sure what to expect.
If you choose to overclock 970 chipset motherboards just do NOT cut it. They lack adequte vrm phase control. 6x2 is a minimum. Better temps and control with 8 x 2. I am sorry to tell you but a $100 motherboard just isn't going to do the job. For $149 you can get a Gigabyte 990FX UD3. It has 6 x 2 phase control and will be afar better choice than a 970 board.

NO NO NO! You can do a 10% overclock to 4.4 possibly 4.5 GHZ on a stock 4.0 GHZ FX 8350. But after that the limits of overheating vrm's will come into effect.

Never ever do that. Everyone says you don't touch PCI or PCIe bus and they're right. When I was a noob I didn't lock my PCI bus when I was overclocking and I corrupted my hard drives completely and had to reformat.

Im glad u edited your post about your cooling lol much better smile.gif

im not sure on the asrocks bios but im guessing it will be a bit like asus bios. as its a sister company

Is there something called ai overclock tuner or something to that effect?

You need to turn that to manual

then on cpu ratio you can turn that up to 22.5
for fsb clock you can leave that on auto as it should stay on 200. if not then manually change it from auto to 200
vcore is next hmmm lets stay at 1.40 see it boots and test how stable it is you may need a little more or a little less. Im thinking more because it is the 8320

you may also have to fiddle with the digi vrms but lets cross that bridge when we have to.

you may find the wording differently but just take a screenshot or write it down and we can go from there

also check out this guide its well wrote and youll find it interesting smile.gif

I saw that Asrock 970 Extreme3 VRM is 4+1 phase. Is it even good for OC'ing and if it is,what's the limit?
Appreciate.

The 970A-UD3 is $100 and has 8+2 phase. It's a cut down 990FXA-UD3 with blue PCB and fewer PCI-e lanes, that's all. Quite the difference from the 970A-D3, believe me.

Thanks a lot! I'll go for 990FXA,as soon as I'll re-place my PSU and sell my Asrock.
Thanks! Really appreciate! smile.gif
