Been playing with DFI's latest 4/28 pre-public beta bios and it seems to have improved memory clocking stability for Elpida IC modules as well as improved my max H20 cooled bclk validation from 233 on 3/28 pre-public beta bios to 235bclk on 4/28 bios. 4/28 is pre-public beta so flash at your own risk from here.
4/28 bios seems to be more tolerant of very tight subtimings .. so close to sub 9min 32M pi at <3900Mhz!
sub 4000Mhz 32M
