Notes:
1. The -15E speed grade is backward compatible with 1066, CL = 7 (-187E).
2. The -15 speed grade is backward compatible with 1066, CL = 8 (-187).
3.
t
REFI depends on T
OPER
.
4. The CL and CWL settings result in
t
CK requirements. When making a selection of
t
CK,
both CL and CWL requirement settings need to be fulfilled.
5. Reserved settings are not allowed.
