We are working with the H8QGI-F and we are testing it with MELANOX conectx 2 cards.
In order for the card to reach max throughput I must work with PAYLOAD of 256b.
The driver shows payload 128b.
The throughput shows only 60% of max and according to Melanox support it must be at least 256b.
I am working with bios 1.1 and I can’t see the option.
BIOS didn't have this option since AMD SR5690 only supports payload size 128B.
