Footnotes

  1. Here, this is L4 cache.

  2. CEX, Cache Expanded Memory, is a technology allowing the use of register-like memory as RAM. This can quadruple memory bandwidth but is a very expensive type of memory. Cannot be combined with normal RAM.

  3. Octa-channel memory requires a motherboard with eight or more memory slots.

  4. Faster speeds require CEX memory
