Good design, good overclock, good pipe-The MSI P35 Neo2-FR overview

[monographix]

1.
I got this board and i placed an 8800GTX in the white PCIE slot thinking that this is the 16x (#1) and the card was crawling at 9fps in 3dmark06 WTH ... i went to bios and changed the PCIEx4 speed controller from auto to 4x and disabled "Auto Disable DIMM/PCI Frequency" and 3dmark06 run 85-35 fps showing normal function

Is there a chance that the physical 16x is the yellow one ???


2.
with any bios version above 1.3 the CPU (Q6600) voltage options in the cell menu start from 1.300v, the only bios from the ones i tried (1.3, 1.4, 1.5, 1.6, 1.76) that gives correct values in this field is v1.3 . The actual voltage the CPU receives seems to be right (aprox 1.260?), looks like its just the menu options that are labeled wrong, for example the 1.300 option corresponds to 1.252-1.272 of actual voltage. Again, WTH?


3.
I have two sata drives. Is it normal that in AHCI mode they are detected only in two of the four ports? ("3" & "4" i think)

Also, is there a way to get rid off the annoying USB scan beeps on POST ?
And is it possible maybe to disable (or selectively disable) those usb checks anyway altogether ? (or speed them up. i have lots of usb stuff on)
