From looking at the source code I don't believe it will work... I don't 
think it will work with v5.0 either...

Hi Mikhail

In MPMC v4.03 I don't find any hint that 1:2 clock ratio is not
allowed for DDR1.
In v5.02 the 1:2 clock ratio is described in chapter Performance...

Have fun

Does anyone know if I can run DDR1 type of memory at double the frequency of 
MPMC4.03 (EDK10.1) main clock? Or is this possible for DDR2 only? I am 
having difficult time trying to understand this from the datasheet. So, 
before digging into the MPMC source code I thought I would try asking...


Thanks,
