* From: roberto@keltia.freenix.fr (Ollivier Robert) * One thing to consider is that you'll suffer a 10-15% speed penalty with ECC * RAM. (number from some -hardware mails in the past). To clarify: 10-15% penalty on maximum memory bandwidth. (E.g., 70MB/s vs. 64MB/s on TritonII with 66MHz bus and P5-133.) This is NOT the same as application speed penalty, which obviously varies depending on how memory-intensive it is. Satoshi
