For the past 24 hours since i have set up my new computer, i have just been testing out Overclocking and im enjoying my self, being doing a lot of reading and watched a few videos on the matter, anyways here is my specs:

CPU: FX-8350 4.0ghz Overclocked to 4.5ghz
Motherboard: M5A99X EVO R2.0
GPU: VTX3D 7870 LE Black Edition
RAM: 16GB 4x4 Kingston DDR3 Dual Channel 1600mhz
Cooling: Asetek 510LC Liquid Cooling system w/ 120mm Radiator ad 6 120mm fans
OS: Windows 8

So ive got it set up at 4.5ghz, ive tested it with:
Cinebench: CPU 7.73 OpenGL 77.23
3DMark11 Basic Edition: 7609
Unigine Heaven Benchmark 4.0 Score: 1341

Here are all my bios settings and few other screenshots: http://s129.photobucket.com/user/PipsonFM/slideshow/Overclock%204500

So for the experts:
Im running 4.5ghz at 1.4V because at the default 1.38 it simply failed CPU stress test.
This is my first overclock and bios settings are based on what i read, is there anything i could change to make it better? click on link for bios settings.


Now the real deal, advice on going towards 4.8ghz and keeping temps low??

Getting to 4.8 im guessing it will be trial and error with the V, i just want to know if someone who is more experienced could look at my settings that i have selected, whether the stuff that i have enabled and disabled and etc are correct

Can anyone give me an advice if the settings i chose in the UEFI Bios for my 4.5ghz are correct or not? I changed alot in cpu config,digi power and etc... i just wanna know if i changed too many things, i disabled or enable somethign i shouldnt have and etc...

You should be getting better overclocks with a closed loop water system... I use a CM hyper 212 evo on my 8350 and I get 4.7ghz at 1.350v (keep in mind I got quite a good chip)

Pipson, I am not so sure O5akari23 is getting 4.7 ghz at 1.350 v. I have been working with the 8350 for almost 2 years and I have never seen a chip than can even pull 4.6 on stock 1.38 v. much less 1.35. Usually, and remember it varies with processors, 4.8Ghz will require a voltage around 1.48 or somewhere in that arena. 99% of the time I can get 4.4-4.5 Ghz on stock voltage, but as soon as I go up to 4.6 I get failed cores on Prime95, and raising the v .1 at a time usually does the trick. You might have to lower ram speed to attain higher overclocks, but you will have to adjust ram and maybe even ram timings at some point. Ram is only tested to a certain speed, and all ram is different. Also, sometimes higher overclocks are harder to attain running 4 sticks of ram. If you need 16 gb ram, try 2 8gb sticks, but generally 8gb ram is easier to overclock. Ram can play a big role in how high you can go, and how easy it is to get there.

Nope, I definitely get 4.7ghz on 1.350v. I just got a good chip.

Try this out: Cpu Mulit--20.5--Cpu NB x11 2596--CPU Bus Freq 236--HT Link Freq 2596--Cpu Voltage 1.3875--see if it posts. If not, up the voltage in small ammts until it posts. Run benchmark, then back off until it wont post. Then start adding again until stable. Run Benchmark 24 hrs.~~ Some 8350's will require 1.48 or 1.49 on cpu voltage to run a 4.8 Ghz clock. Should be a stable 4.8 Ghz Overclock on an 8350-- Suferbus

My ram settings are 2201 for 8 gb Gskills (2x4gb) with the aforementioned oc @ 4.8 Ghz.
Also, high overclocking stability can be an issues when utilizing 4 sticks of ram. I find it best to just run 2 sticks, less can go wrong and seems to work better for higher overclocks. you won't find many over-clockers using all ram slots. I am assuming you are using 4x4gb to get the 16 gb. If is is 2x8gb, you should be okay, but less ram is still better in most cases.

tried what you said: but one processor failed after trying a blend test within 1min.

Cpu muti = 20.5
Bus speed = 236
HT link and Bus Freq = 2596

and this is using 1.49V
ram at 1599
Everything disabled in CPU configuration apart form
Cpu spread Spectrum/ PCIe/ EPU power... all disabled
DIGI settings:
CPU Load Line Calibration = Ultra High
Cpu/NB load line Calibration = High
Cpu Current Capability 130%
CPU/NB Currecnt Capabliity 130%

Try just overclocking using multiplier. It has to be a ram setting that is causing you to fail so quickly. You will be able to get a more stable overclock just using multiplier for overclocking at this time until you get ram figured out. I would make sure to run only 1 matched set of ram 2x4gb and use 9-9-9-24 2T. you might have to use your XMP ram profile when overclocking using FSB. Now, the performance is better when you use a combination of mulit and fsb overclock, but it is more difficult to get stability on some processors, but it is not dangerous as long as you keep the voltage and temps in check.~~ Suferbus

I tried your setup got the same CPU and MB ... the system loaded but it failed on benchmark and after all it was just failing on everything and froze. But I managed to make my own setup.

here is how I modified it and it passed all stability tests so far but I did not try longer tests like 1 hour or 24 hours .. I need my pc for work so ..

I pulled out 4525 Mhz which is for me final number :) saved the profile and I am happy with it so far.

Please ignore my ram as I only have 1 in the board and another peace is on the way so I will figure that out later or if someone has a simmilar ram maybe he can post tips.

I attach screens:
