X-Ram on Sound Cards?

Question

can someone explain to me what extra x-ram on creative sound blaster sounds cards is/does

Answer 1

X-RAM—onboard memory that can be used by the X-Fi audio processor to store additional voices and higher quality audio assets. Creative claims X-RAM can ultimately improve gaming performance. Fortunately, both X-RAM and additional I/O ports are available on the X-Fi Fatal1ty, with a red LED riding shotgun, of course.

the site posted is where i got it, and the article also says they put the x-ram to the test if you want to read about that

Hope this helped
