I'd suggest this to you.

Install a side blower in your case if you don't have one where it can direct cool room temp air on the RAM.
Next if you have to buy a quality thermometer and attach one or more thermisters to the heat spreader. Get some accurate temps at the highest voltage and O/C you can run at under full load.

Now remove the heat spreaders and repeat the testing @ the same settings, then try for a higher O/C.

At Directron they have some skived fin heat sinks for system RAM. I'd suggest you buy sets of that and attach with thermal epoxy. Again run the same tests.

I think you'll find that just taking the heat spreaders off will drop temp & increase your O/C, may be only a small gain, but I'd bet you'll get a gain.

Adding the heat sinks will also give a boost if you are pushing a pretty high O/C at a good high voltage (3.2+), and the higher the voltage the more it'll help.

There was a thread on this topic a while back at Xtreme Systems. Most, but not all, who ditched the heat spreaders made some gain. And a couple who added heat sinks gained more.

For those after MAX O/Cs a few extra mhz gained on the FSB is well worth the cost of finned heat sinks.
