ASUS Maximus Formula SE

[Talonman]

I am confused on the memory for this board: (Newbie)

It has for info:
Dual channel memory architecture
4 X DIMM, supportmax 8GB, DDR2-1200*/1066/800/667 MHz, ECC, non-ECC and unbuffered memory
DDR2 1200 is O.C. speeds.

So if I want to buy Crucial 4GB kit (2GBx2) what memory kit is best?

Here is one that I am looking at:

http://www.newegg.com/Product/Produc...2KIT25664AA53E

and another:

http://www.newegg.com/Product/Produc...2KIT25664AA667

Are these the type I need the the Maximus SE, what is the best Crucial 4GB kit (2GBx2) that I can select, that the board could actually make use of on a high memory OC?

Thanks for the help...

I want to get my memory on order for this baby....

*Update: I noticed the top link is Cas Latency: 4, the second is Cas Latency: 5, but the same price? Isn't that odd?

I guess the top link 'DDR2 533 (PC2 4200) CT2KIT25664AA53E' would be a good choice correct?
