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

What is  DQ UI (ps)?

Rank Margin Table Equations

RX Timing Margin (each step = 1/64 * DQ UI (ps))

RX timing setup = RxDqLeft

RX timing hold = RxDqRight

TX Timing Margin (each step = 1/64 * DQ UI (ps))

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?
