I built up one of these about a week ago and have been messing with it since then to work out some issues. Here are the specs:
NSK2400
Replaced the Tri-cools with 2 Yate Loons, 5V
TR SI-128 (passive)
Brisbane 3600 X2
SuperTalent 2x1GB DDR2 667
XPSP2 32-bit
I'm on that 4/19 BIOS right now and it's got a coupla issues. One is that after resume from Standby (S3), the "automatic overclocking" resets to normal mode, BIOS still says "V12".
I reported this to Biostar and they're to have a fix soon. Also, I reported the "missing" Smart Fan settings in the BIOS, they say it's been removed, in lieu of the new Windows-based Fan Control Utility. I've reported some issues with that.
I was able to boot/load Windows @ 260, memory @ 533, more volts, but it was not stable running SP2004. Ended up being stable at 250, memory AUTO at 2.05V.
There is apparently a problem with the Brisbane DTS, basically it's not reliable. I have very cool BIOS numbers under PC Health, I have 10+C numbers using the Biostar Hardware Monitor in Windows and CoreTemp reports insanely low temps, simply cannot be accurate.
Everest reports a "CPU Temp", but it never changes from 40 degrees C, no matter what I do. Speed fan is the same. SPeedFan does not yet support the chipset, but I've submitted the info to Alfredo, so he's on it I presume.
RMClock totally screwed me up when I tried it, but then, I'm not very familiar with it. I could never get it to throttle down and when enabling managment features in RMClock, it would eventually end in an hard-lock.
Looking forward to hearing some more from other folks. For an mATX board, I am extremely impressed with this first-run unit. I will build at least two more machines with this board.
