The E6 stepping has some erratas (113, 114, 116) fixed that were present in the E3 stepping.
-Errata #113 - Enhanced Write-Combining Feature Causes System Hang
-Errata #114 - DDR Data Pin Drive Strength Also Affects Command/Address Pins
-Errata #116 - DDR Chip Selects Tristated One Clock Early in Power Down Mode.
Evo ovo sam našao. Još samo da zam što je errata
EDIT: errata sheets su popisi problema tj hardwerskih bugova-ili tako nešto.
