P7P55D-E Pro best memory to use?

[GMJim]

I'm using a Asus P7P55D-E Pro board http://www.asus.com/product.aspx?P_I...n2V&templete=2 and an i7 860 CPU and am having trouble deciding on memory. I don't plan on gaming heavily but may do some in the future. I use my computer for general use and photo and video editing. I want my system to be as fast as possible yet stable as a rock. Now on to my question.

Is there a noticeable difference from 1333 to 1600? When would the 1600 be most advantageous.
Here is the ram I'm thinking of buying. Do you know if this ram has Intel XMP (Extreme Memory Profile) Support?

8GB of G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-4GBRL

or 8gb of G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Desktop Memory Model F3-10666CL7D-4GBRH

If there isn't a significant difference in real world performance would it be better to go for the 1333? If the 1600 is better is it considered overclocking if I use it and is it difficult to make the necessary changes in the bios? XMP?

Thanks
Jim

With this motherboard and CPU, any DDR3-2000 and below memory package should have no issues. Simply enable the XMP Profile in "Ai Overclock Tuner" and everything will be automatically set. 1600 is the maximum speed without adjusting CPU settings, but with this motherboard you can simply enable the XMP Profile, so even DDR3-2000 would be fine.

If you are using this for photo and video editing, I would suggest a low latency CL7 memory package. Otherwise a DDR3-2000 kit would be great as well.

The DDR3-1600 memory package I would recommend is the G.Skill F3-12800CL7Q-8GBECO

This is not only a fast DDR3-1600 CL7 memory package, but it is also low voltage, so if you have your computer on for long times, this would surely benefit you by using less energy and providing great stability.

Thank you

Thanks very much for the reply. Had I got this this morning I wouldn't have bought 4gb of this. http://www.newegg.ca/Product/Product...82E16820231276

I decided not to go for 8gb right away because of my lack of knowledge in this area. I thought Ripjaw was a better line. I will consider returning the Ripjaw 4gb and buy what you suggested if you think it's better. Could you tell me what this means at the bottom of the description on your web page?
*G.Skill guarantees 2 Dimms dual channel operation would reach announced specification.

Thanks for the help.
