If you use atom/ulv mobile, it will be 800.
If you use bloomfield, it will be 1066.
If you use lynnfield, it will be 1333.
False.

tks for the lengthy explanation, appreciate that, btw do you have a webpage link whereby i can learn how to do oc ? Currently my ram is 1600MHz, I still have not maximise its full potential yet, keen to learn.
tks.
I would do a guide, but my desktop's disassembled.
However, this is an excellent guide by Tom's Hardware.

And it's for AMD systems, so it's right up your alley.
Do take note that the RAM may not run stable at 1600MHz because the memory controller on Phenom II chips are not as robust as the controllers on Intel chips.

Hi Raraken,
Thanks for the link, I'll spend a few day to read up & try to do a oc myself, if encounter any problem, I may need your help.
BTW how do you know that ram run above 1600MHz is not stable on Phenom II chips, you learn thru trial & error ?
Your "unstable" means the system will hang occasionally ?
Then how come those hardcore gamers still want to oc their system (Phenom II) if its unstable, pls enlighten me.
Thanks for the reply.

It's a well known fact that the memory controllers on Phenom II chips are not as strong. Yes, you can get the RAM to run at 1600MHz and above, but there are right now only specific memory kits and board/CPU combinations that work well.
One example is the GSkill Flare 2000MHz C7 RAM kit. These modules are meant to be run in an AMD system, but will only work at their maximum potential (2000MHz at CAS latency 7) on a rig using an X6 CPU and certain ASUS motherboards.
Most RAM modules are meant to be run in Intel systems at the higher speeds, so they are not optimized for AMD memory controllers. You can get them to work at high speed, or somewhere close, but it will require a lot of tweaking. I've had my Team Xtreem running at 1600MHz, but at C8 and higher voltages (around 1.75V) rather than the C7 and 1.65V I would have gotten on Intel.
By "unstable", I mean BSOD. Very frequently.
Why hardcore gamers want to OC their Phenom II systems? Because OCing is fun. AMD Phenom II chips can overclock like there's no tomorrow. I've successfully gotten my 955 to 4.3GHz, limited by the motherboard's power delivery system. The instability comes from pushing components too hard. As I've said, overclocking is dangerous and very difficult to get high speeds. But once done right, you get the feeling of satisfaction and pride. And if you aren't overly ambitious, you can get a perfectly stable overclock very fast.
sorry to hijack the thread... I'm currently going to upgrade my com with more ram, as I still have 2 slot free...
is it better to get another 2 ram of the same make as the current ones I'm using or can i mix and match different brand?

In theory, it's best to get similar RAM sticks to the ones you already have i.e Buying Corsair XMS3 1600MHz sticks if you have Corsair XMS3 1600MHz sticks already in use.
However, in reality, as long as the modules are of the same speed it should work fine (like buying Team Elite 1333MHz RAM sticks if you have Kingston 1333MHz sticks already installed)
