Crap, I was looking everywhere for newer bios, did not know they were listed here! Found via google.
The author of cpuz is trying to get Cas corrected, it is bug in cpuz, I sent him some dumps as did others, should be corrected soon.
By the way, Gigabyte nice job on quality board with GB X58 Ex!! no problem getting 4ghz (with turbo enabled for 4.2 single core) prime small ffts stable 9hrs. Small learning curve since all new, but love the board!
I agree about QPI, nice to keep that at stock 6.4 or lower, no benefit on desktops to higher...need more multis, like 48, 36, 32, 28, 24, 20.
btw...did I say I love the board!
Edit: holy crap, some timings/volts or something must have changed dramatically in F4E. F3 I am prime, linpack, memtest stable. Using F4E, barely got it to boot after few tries w/exact same settings. Prime caused immediate reboot. back to F3, booted right up w/same settings, priming away. Think I will wait on F4 until done.
