I ran the quick regressions and it seems at least the readPktSize stat changes significantly even with a DDR3 that has a 64 byte burst size. I haven't yet figured out why, but it would be good to understand better why the masking changes the stats. - Andreas ----------------------------------------------------------- This is an automatically generated e-mail.
