Rank Margin Tool

[shiv_a_]

Does anyone know what the Rank Margin Tool is?

[Bernard]

Is that tool related to DRAM?

Bernard,

Did you get answer of your question?  I am looking for the same.   Is this this RMT tool for system level test or memory device (DRAM) evaluation?

Thanks

Wen

Rank Margin Table Equations

RX timing setup = RxDqLeft
–
RX timing hold = RxDqRight

Hi everyone,

I'm getting Mixed Memory Speed warning after getting the Margin Tool to analyze the data.

Where do I go from here?

Do I check with the bios settings?

all four DIMMs are the same model and same vendor.
I'm looking for answer why I'm getting mixed speed.

Can someone help?
