Very helpful, thanks! Just tried it, tRD adjusts performance in DQ6 as well, somehow missed that.

Does anyone know besides secondary timings what else turbo or extreme adjust versus standard? I have all timings on manual except phase, and with bios F6 set on turbo or extreme instead of standard, I still get improvements in everest measured read (from 9350 to 9500) copy (from 7627 to 8425) and latency (from 54.4 to 52.9), and spi (from 13.04 to 12.95), despite all memset visible settings being same and all everest memory timings listed under chipset same.
