DFI X58 - i7 920 max bclk on AIR = 230Bclk NOW 233Bclk
Max 230Mhz BCLK
I had all but given up after I found my initial max Bclk 32M Pi stable BCLK of 220Mhz with tight 878mhz 7-7-7-17 timings.
But I'd like to thank Hazzan (233BCLK) and Solarfall (230BCLK) for their inspiration with their DFI UT X58-T3EH8 max BCLK attempts as this prompted me to keep working at it
After numerous bios reboots and trying looser timings and a few voltage combinations, I finally surpassed my previous max memtest86+ v2.11 bootable BCLK of 224, moving all the way up to 230-231 memtest bootable.
Enough for a quick boot into windows for a CPUZ Validation at least
