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!

nice..... i dont know why more people didnt catch onto that board... i liked mine before i sold it.
 
Yeah true.. maybe it's due to folks thinking dfi x58 has tricky bios options like past x48 boards, but the fact of matter is dfi x58 has less bios/timing settings than other brands asus/gigabyte/evga etc all have more timings/options than dfi x58 heh

Starting to hit probably thermal limits of my i7 920 3836A756 on H20 cooling as 32M Pi seems to be topping out around 4680mhz with HT disabled. Only managed to shave ~1 second off my best 32M pi time with i7 920.

If I won't find an answer to my Gigabyte EX58-Extreme + Thernaltake PSUs then I'll probably get one of these.
I've used DFIs before the LP era, very stable and lovely boards.
