Which ram for i7-860

Pretty decided on the below build minus RAM

Case- CM 690
MB- ASUS P7P55D EVO LGA1156
CPU- i7-860
Cooler- Dark Knight cooler (and 1156 bracket when it comes in)
Video- ASUS/XFX/Saphire 5850 (probably whichever I can get my hands on first)
PSU- Corsair 750TX
Hard Drive- WD Black or Samsung F3 spinpoint (lots here love the Samsung, but makes me nervous...)

RAM Options I was considering:

G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) 8-8-8-21 / 1.5v $85

Thanks for taking a look. I don't really have a 'budget', but I'm just looking for the most cost effective option. I'm leaning towards the $95 option as it has decent timing and rated for 1600.

Thats what I was wondering... OC'd memory freq vs timing

I think I'm leaning towards the $95 set, decent timings with 1600 freq... I'm probably going to load it with 8GB as I'm fairly certain the cooler will over hang the slots and make it more difficult to upgrade later.

Can anybody confirm that this ram (with decent size risers) will clear the Dark Knight on an Asus p7p55D 1156 - also looking at the Zalman CNPS10X QUIET as the brackets are still out for the Dark Knight
