Yeah I know...
I'm wishing it had the old set of options for bank interleaving.
Instead of auto I want the "address bits 12" setting.

Don't wanna upgrade the bios to the 3x ver and lose a good chunk of bandwith .
I'de make the switch to the 3x ver's IF they had that 1 value, performance should be close enough afterwards.

It really does seem like it's the main slowdown there to me.
Perhaps there's a bit more to it, but I honestly think that's most of it.
