Corsair XMS (TWINX2048) PC3500LL PRO DDR
 

The LED's do not just light up or not, they actually scale from a few lights to all the lights depending on the current RAM usage. Corsair has turned the normal RamSink into a light show by including LED lighting in the top edge and also embossing "XMS" right into the covers.
