Corsair XMS PC-3500LL Pro 2GB
 

Those with a good eye will notice that the XP-90C heatsink in this picture is mounted upside-down. The heatspreaders make these modules too tall to fit under the fins and in the dimm slots. Thankfully, it just barely cleared my videocard when mounted upside down, and I was able to fit the modules without issue. This is something everyone should be aware of.
