Tref conflict value in bios - AG care to comment

[BB_One]

I just came across this in trying to help someone and frankly do not have an answer to it, maybe AG or Rgone could query engineers or have an explanation for this one.

 

Look at this table and notice the redundant entry for value 1032, this is not a typo in the chart as I originally suspected, but in fact also in the bios of nf3 or nf4.

 

Is this a typo in the bios hence one setting for tref is gone missing because of it?

While we are on this subject, does anyone have a clue about the values (entries) for the µs identified with ??.

 

Thanks for your help.

Hello,

 

What do you think about this?

It looks like the two settings are not quite the same. I think one bank is a slightly relaxed version of the other (same MHz, different microseconds).

Nice info and in some instances refers to the same document...still puzzling question is how come twice the same value (1032) in the bios, and for different latency in theory?

 

Not sure my math skills are what they should be, for from Rgone's formula I am kind of puzzled as to how to get the missing values?

 

Vista if you pay close attention to my post and the table originator and the link you provided you will off course realize that those are the same charts and from the same originator...hence question is still valid and not answered.

Cannot be, for both have the same entry value in bios ---> 1032...hence one tref setting in bios missing...

They might have the same label, but they are different bit settings doing different things.
