Hi Adzim,

I tried the auto-precharge control option but with no change.

also the address ordering.

it seems strange because we are talking about only 15 gbps throughput, when the maximum theoretical throughput is 25.6gbps with this chip and the memory devices.

there could be difference in the throughput between using one port bidirectional, or two ports when one is for write only and the second is for read only?(see our ip settings).

I don't know where else to search,

I will appreciate if you find more options,

BR,

Ram.
