Memory Subsystem
The Octane supports 256 MB to 8 GB of system memory, using proprietary 200-pin DIMMs. There are two system board revisions. The first revision (part number 030-0887-003) supports 2 GB of RAM, while the second (part number 030-1467-001) allows up to 8 GB. The memory subsystem has vast reserves of bandwidth that can be directly served by the Xbow router to any XIO card.
The Octane's memory controller is aptly named HEART. It acts as a bridge between the processor, the memory (SDRAM) and the XIO bus.

Famous quotes containing the word memory:
“Memory is like a purse,—if it be over-full that it cannot shut, all will drop out of it. Take heed of a gluttonous curiosity to feed on many things, lest the greediness of the appetite of thy memory spoil the digestion thereof.”
—Thomas Fuller (1608–1661)
