Hmm. Trying to push an SDRAM DIMM into a never used before slot on a new motherboard, and it seemingly required so much force (no, I didn't have it backwards, I always test-seat them gently beforehand), that my fingers ripped off one of the capacitors near the top of the DIMM. Since they were PC100, and the system was only running them at 66Mhz, it still seemingly worked, but I no longer trust that one to use in an important rig.
I don't understand why DIMM slots, and Socket370/A heatsink clips, require so much dang force. Why don't they drop the whole "ZIF socket" thing, and go back to the old type of evil high-insertion-force socket too. I mean, really. (Why can't they invent a ZIF socket for DIMMs? It wouldn't seem impossible to me.)
That reminds me - anyone remember SIPP memory? That stuff was kind of a fun PITA to upgrade too, especially if you bent a pin.
