FELIX - I'm trying to "translate" SPD, BIOS, and MemSet readings on a P35 as well. I fully understand why the terminology is used in MemSet and just wanted to make sure I understand a couple of items:

Sorry if this is remedial or obvious, just like to be sure.

-Write to Precharge delay = tCL + 3 + tWR
-Write to Read Delayed = tCL + 3 + tWTR

Would that be accurate?
You mentioned (spd), but if tWR and tWTR is able to be set in BIOS that is still used instead of spd, correct?

MemSet
RAS# to CAS# Read Delay
RAS# to CAS# Write Delay

Both of these can typically be from a "RAS# to CAS# Delay (tRCD)" setting?

MemSet
Read to Write Delay (tRD_WR)

This is also referred to as tWR?

And tRC is not used at all as P35 MCH doesn't have or use it, correct?
