New to Overclocking. Need Advice.

Specs:
AMD Quad Core 955 (3.2 stock) - Arctic Cooling freezer pro rev.2
gskill (2x4gb) 1333

Corsair 650w

I'm a beginner overclocker. Yesterday, I overclocked my processor from 3.2(default) to 3.4 by changing my multiplier from x16(default) to x17. I ran prime95 overnight for about 7 hours without any errors. My temps ran about 30 degrees idle and 49 degrees when cpu was at 100%. So I think this means I have successfully overclocked my processor from 3.2 to 3.4 because its stable?

Afterwards, I overclocked my processor again from 3.4 to 3.6 by changing my multiplier from x17 to x18. I already played some heavy gaming with my processor overclocked at 3.6. I plan to run prime95 against overnight for stability testing.

Before I did all of this, I used CPU level up in my BIOS. I think this feature is only used in ASUS motherboards. It gave me a choice for an overclock to an AMD 965 that changed my cpu bus frequency and gave me 3.4 (965), but it upped my ram from 1333 to about 1440. It was unstable because my computer was crashing on desktop. I put everything back to default. I tried this a second time but dropped my ram lower than 1333 and it seemed stable without stability testing. So I think this means that my computer will be unstable if I do anything above 1333 or I'm not overclocking my ram right?

I currently haven't changed anything else in BIOS for an overclock including voltages because I'm not sure about those. I'm afraid I might up the voltages too much and burn my processor.

I would like some advice on overclocking. Are my methods of overclocking correct? What temperatures are not good? If something becomes unstable like a processor or ram, does this mean I have to add more voltage to make it stable?

Also, what programs are needed for overclocking. I currently have an ASUS program that tells me the temperatures, CPUZ, AMD overdrive (not sure if I need this because I already have CPUZ), and prime95 that I used for stability testing. Is benchmarking really needed? Isn't benchmarking a program that just tells you how fast your processor is running compared to other processors?

My current overclock - cpu 3600 ram 1333

If you do that 965 OC mode on your motherboard it looks like your ram will need increased voltage to run at where it was before setting it to 1333.

Edit:Btw your links don't work for me.

Thanks for replying. Fixed Links.

How much volts do you think I have increase to lets say reach 1600

CPU level up overclocked the bus clock. Which overclocked the RAM. Which, obviously because you have generic RAM not meant for overclocking, turned out unstable. Use the unlocked multiplier to OC.
you might be able to reach 1600Mhz with some 1.65V, but I doubt it. 4GB DIMMs with 1333 CL9 settings don't usually overclock well.

If you purchased recently, you could've gotten a 1600 CL9 2x4GB kit for a full $10 less. Such a shame...

Tom's did a small piece.
Hope this helps. I've never actually overclocked an AMD CPU.

Thank you for all your replies.

I have a question... whats better? overclocking your cpu by changning the multiplier or changing CPU bus frequency if I can make it stable with either method?

Prepare to be held back if OC-ing by bus frequency due to the generic 1333 CL9 RAM
Your best choice would be a multiplier OC

I was watching my temperatures while using prime95. My cpu was at full load and I got two temperature reading. One if CPU temperated at 52c and the other one was a core reading which was at 62c. I heard that 62c was the max, but I dont know which one it was referring to, cpu or core temperature?

I believe it refers to the core. On Phenom II x4/x3/x2 processors the core reading should be trusted unlike x6 where you trust CPU temp. Looks like you hit the max.
