Ok, so I have some new RAM. It has the large heatsinks which are attached by metal strips that fold over the edge of the memory cards. Now, my question is this: when I install the RAM is it ok to press on those strips, or do I have to push the card edge directly? On the one hand I don't want to do anything that loosens the heat sinks. On the other, I don't want the imprint of a circuit board edge on my fingers for the rest of my life Thanks.
