Hi community,

   I use a new DDR3(W632GU6MB12A) for my customer board(I.MX6D) and the board get stuck at high ambient temperature sometimes.So I measure the temperature of the DDR3 and it is 93 degree. Accordding to the DDR3 data sheet:

   The case temperature can not be less than -40 or greater than +95. JEDEC specification require the refresh rate to double when Tcase exceed +85.

   So what should I do to fit this feature?Can I just change the configuration of the <DDR3 Script Aid.xlsx>

to double the refresh rate when Tcase come to +85 to +95?

 

 

Best Regards,

Azmat
