which memory?

[DocMartin]

Which memory would be best with a i72600k cpu?

Item# N82E16820231445 at Newegg g.skill ripjaws X Series 8gb (2x4)

or Item# N82E16820233147 corsair vengeance 8gb (2x4gb)

With 2 good brands like that, with identical specs, it would come down to price for me.
The heat sink looks taller on the Corsair, if space is an issue.

I've been buying GSkill, for a while now, because it is usually a little cheaper, and just as good, as my old favorite Corsair.

You're not going to notice a difference in them except benchmarks and your wallet.

Agreed.

Newegg currently has these ones for $59.99, about $20 cheaper, same speed as well:

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

Just a Higher CAS Latency of 9 instead of 8. Other than Benchmarks you probably aren't going to notice it much.

the CAS 8 basically allows you to run it at "looser" timings if overclocking beyond the 1600 rating for stability. otherwise little noticeable difference between the 2.
