Honored ContributorRunning SDRAM at double speed
I currently have a NIOS1 design (but I think this will apply to NIOS2 as well) running at 60MHz, with 16 MB SDRAM. The internal SOPC clock is PLL-ed to 60MHz and the E0 output (also 60 MHZ) is ...

Honored ContributorAs far as I know, the frequency of the sdram clk equals to the cpu clock, can your Nios run at 120?
Even if you can optimize your cpu to run at 120, I cannot remember where I had read an article said that the max frequency of the sdram controller is 100.
