Thx for the update.......

First off.. It is important for you to know that the 8550 is not a great overclocker regardless if its a BE or not..... They are basically defective AGENA chips that did not pass quality control and were set to be used as dual cores... The highest overclock I have seen with a 8550 is 3.4Ghz (stable) on a UD4P 790X motherboard....

Second, I do not recommend using 2 different sets of Ram if you plan of having a stable overclock. It basically puts more stress on the chips memory controller and does not help to attain stability....

I recommend you remove the off brand Ram and just use the 4Gb of A-Data for now... Later on you can add the other sticks when you find that your system is stable....As far as your cooler goes, you can overclock to about 3.2 / 3.3Ghz anything higher will give you high temps since you will have to raise the voltage...

1.4v should be enough for your CPU since it will not go past 3.4Ghz....Another thing you have to consider is that your mobo is not the best overclocking board so that might be a reason you will hit a wall at such low overclocks....

Try these settings :

Leave the bus at 200mhz <-- once stable you can raise a bit.....
Make sure cool n quite is disabled
Change the CPU voltage to 1.375v <--- Dont go any higher than that for now....
Make sure the NB voltage is @ 1.35v / 1.36v for now......
Multiplier @ x14.5 , if unstable lower to x14....
Chipset voltage should be around 1.10v / 1.15v MAX

Make sure your Ram has enough volts to operate @ 5-5-5-18 and run memtest just to make sure your settings are correct. The first thing you should do before overclocking is making sure your ram is stable at it's advertised speed.... Once that is done you can play around in the bios till you get a stable overclock but remember to raise in increments (little bit at a time)....

Btw I have a 7750 (2.7Ghz stock) running on a decent motherboard and it wont boot past 3.3Ghz.... The only BE's that can achieve high overclocks are the x2 550's, x3 720's , x4 940's and x4 955's ..... Let me know if you see a bios option that might need some tweaking, I am just going by the settings that I use.... hope this helps...
 
yeah thank you very much, i am gonna try that tomorrow, i have been playing ruins of magic for the past 3 hours and am kinda sleepy, thanks again!
