Which memory is best for overclocking?

[paradoxeternal]

Hi, I've decided to upgrade my system a bit and want to overclock. I currently have an AMD Phenom II x6 1100t and an AMD Radeon HD 6870. I'm currently using an older motherboard with 800mhz DDR2 memory. Until i make my upgrade decisions, i'm going to overclock my CPU using the multiplier only.

However, I'm not sure what memory to buy. I'm a bit confused about memory speed and voltage-- From what i understand, 1600 mhz is the standard for gaming now. I'm going to game but I also do a lot of video editing and rendering; i'm pretty sure that 16 GB of 1600mhz memory would do me just fine for a while. However, I know that when overclocking you need to raise the memory speed. I also know that a lot of memory doesn't actually run at the advertised speed--at 1333 instead of 1600, for example. So would my "overclocking" involve raising the speed from 1333 to 1600, or raising it above that to a higher speed?

Also, what kind of voltage should I be looking for? I'm pretty sure voltage should match the CPU, but should it also match the motherboard's voltage?

Finally, here are the 3 things of memory i'm looking at: which is the best for overclocking?

Which of those is best and most compatible with my CPU?

First of all OC'ing the RAM does not provide much improvement is system performance. Second if you fill all of the DIMM slots most mobos will only run at the RAM at the default RAM frequency for the CPU which is 1333 MHz. for the Phenom II. You use the RAM voltage specified by the RAM supplier. The default DDR3 RAM voltage standard is 1.5v.

All of the RAM you list is DDR3 but you indicated your current mobo uses DDR2??? The new RAM *should* work with the Asus 990 FX chipset mobo but IME Asus mobos are very RAM sensitive so I do not recommend them.

so will the G. Skill ripjaws give me any problems since they run at 1.65v? and if you say the asus mobos are memory sensitive, how about this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16813128509
