RAM Heatsinks/Spreaders and Overclocking -- do they do anything?

[WhipperSnapper]

I just finished reading Anandtech's excellent article about overclocking the Venice chips and I was wondering whether or not adding heatsinks to RAM stucks has any benefit at all.

If so, which ones would be the best? I've seen some copper ones at Geeks.com, though I can't say I'm thrilled with a conductive and inductive material.

Are there any good articles or reviews that specifically address this subject.

Hey Anandtech--how about an article on this specific subject to complement the article about overclocking the Venice chips? <Hint> <Hint>
