wireless usb is problematic w/ heaps of other boards too (eg my thinkpad w/ xp x32).
but its probably worth to wait for yet another bios ver.
as for the raid prob. you need the sp2 and the two driver floppy disquettes prepared
for the beginning of the install time (msm and gsata) - dont forget to press F6. After that you will be able to use the intelMatrixStorage tech. I was able to build two different raid volumes
(0 & 1) using only two wd5000ys hdds. one for security one for performance and the third one
is the system disk i boot from.
Dont forget to enable the ahci or raid mode in the bios - depending of what you need - this may be also the source of your eSATA problems. check the provided dongle and eSATA
cable - they are not the best quality - i was lucky and my chep ext HDD eSATA w/ the stock
cable - provided by the hdd enclosure manufacturer - runs flawlessly.
All the drivers are perfectly fine, just dont forget to download all the latest drivers for everything.
Other thoughts:
I am running xp x64 edition, which is notoriously hard to find-drivers-for and the only thing which is not working (crappy unmaintained drivers) is a pinnacle pctv pro AnalogTV/FM tuner card (i don't really care about it anyway).
My setup:
cpu: Q6600 (fsb at 400 x6Multip)
ram: 800MHz pc2-6400 5-5-5-15 4GB (2x2GB) (1:1 memory:fsb ratio)
mobo: see the topic

system disk: 1x wd5000ys (partitioned to 4 diff partitions for linux, xp x32, and other stuff)
raid0 & 1 (131GB & 399 GB espectively): 2x wd5000ys.
windows xp x64 (as the primary OS)
all this w/ a CM 732 case with a tiltable wide screen really makes for a powerful photoshop and multimedia workstation.
If only they (Gigabyte) provided firewire on this board it would be perfect. but that's already solved w/ a 3+1 firewire PCI controller.
I am testing this system (i had to replace the defective ram kit - i am not saying any names ;-) now for two days with different bios multiplyers and it runs pretty stable on the correct settings.
ah yes, my temps are idle: 30C-34C & load: 50C-65C depending on bios settings.
the prime95 v25.3 load on all four cores will generate 50C-51C with the current bios settings. with the stock intel HSF. I plan to replace it w/ a zalman cnps8700 and ArcticSilver5.
I am still in the process of finding a good way to measure NB temps... anyone w/ a solution?
