Cas 9 is fine but since memory is cheap these days, why not Cas 8? This article will explain very clear...Bit-tech's Article: The Best Memory for Sandy Bridge

Frankly, in my experience, it is even worth getting a good set of CAS latency 7 RAM (I have this: http://www.newegg.com/Product/Product.aspx?Item=N82E16820226134&cm_re=mushkin_enhanced-_-20-226-134-_-Product ). I have the 2600k and an ASUS P8P67 DELUXE, and that DDR3-1600 has worked @ 7-9-7-24 without a problem.

I apologize: that link was to latency 9. This http://www.newegg.com/Product/Product.aspx?Item=N82E16820226103&cm_re=mushkin_enhanced-_-20-226-103-_-Product is what I intended to link you to.

If your rig is strictly for gaming, then I agree...save your $24 and go with Cas 9 (although I would still buy the Cas 8 wink.gif). If you're doing some serious video-encoding, you will appreciate the Cas 8 memory thumb.gif

BackerU, I'm looking for 8gb kit though and the link you posted has 1.65v.
Didn't intel recommend 1.5v to have for sandy bridge ram?

drBlahMan, After seeing the review on bit tech about sandy bridge ram you posted, I don't see huge gap beween cas 8 and cas 9 ram from the performance bit tech post.

Well this new rig going to for watching ,blue ray movies,games,music and video converting.

The article was to help you decide what to buy biggrin.gif Like I had stated earlier for myself...I
would buy Cas 8

Ah, very true. The motherboard is the main factor limiting the RAM voltage, and I suppose if you're doing video editing/converting (and/or anything along the lines of Photoshop/CAD) you DO want more RAM, with CAS latency being less important there. I'd say that, at 8GB, you should just go for the 9.
