Difficulty Factor Of This Board Is "10" (grin)
the memory is a bear to set once you go beyond reasonable levels for a dual core and a Quad core, like mine with dual L2's!
i went from 470 fsb to 475 and it required a change in PL level and DDR2 Comp Reconfig...it appears that a 20 fsb jump is going to require to adjust the cpu skew control, mch skew and possibly the cpu pll...i was able to use 1.8v for cpu pll...never could do that before.
also, it appears that cpu skew and mch skew might require a 200ps difference...right now i am using 200ps for the cpu skew and 400 for mch skew.
i am trying to find the balance of memory settings and those skew controls.
it would have been nice for biostar's engineers to list all these changes in the bios in a row (on one page) like gigabyte does for the X48 boards.
I Think I Got It Stable For 490 Fsb @ 8x For My 9650
i've been working overtime on getting to 500 fsb for my 9650...i am currently at 490...i finally smarten up and used the built in Memory test....i was able to find the memory settings and cpu configurations to make it pass the built-in Memtest
i just dual boot installed Vista64 Ultimate, alongside XP, to see if that OS is more tuned with this 710 bios...it installed at 490 FSB @ 8x without a hitch...once i install SP1 on it, i will install the various benches and re-run them.

X48 (ddr3) AGAINST P45 (ddr2)
i thought this was interesting comparison.
i did a PCMARK 2005 bench on the IP35 Pro and then ran it against Gigabyte's X48T-DQ6 (ddr3)...as you can see, the X48 was ahead anywhere between 0 to 8% in the four categories....all the hardware was exactly the same except for the obvious ddr3 memory on giga's board.
what i see now, the P45 chipset is just about X48's equal...the obvious difference is the PCIe 2.0 bus speed..the X48 has 16x link speed for both 16x slots while the P45 offers only one full 16x speed...if you put it into the crossfire mode, the link speed drops to 8x for both 16x slots..you really do not see a big drop with the video card at 8x speed...graphics speed declines only 6% in performance...you kind of get faked out when you see a 8x linked speed for the P45 in the crossfire mode and then observe 16x link speed for the X48...it doesn't even correlate to even coming close, obviously, to a 50% drop.;)
reason i mention this is for users like myself who want to use the 2nd 16x PCIe slot for a raid card like the areca raid card (8x card)....so...i have to set crossfire mode to make the areca card operational, at least on the Biostar board.
EDIT:...need to add the reason for a higher PCMARK 2005 score...mostly due to my new WD Veloci-Raptor drives in Raid 0
