I bought this combo earlier tonight at the Fry's in the City of Industry, CA. It is a Thorton chip and a rev. 8 board.
I'm running right now as we speak and it seems to be stable at 175MHZ FSB.
The back of the motherboard box states that it should have overclocking features (like voltage adjustments), but I don't see it anywhere. The only thing I could change was the FSB. I'm suprised that it is running without changing any voltages. I'm using a generic heatsink with some old 7000 RPM delta fan that I had lying around. I have a 512 stick of Crucial DDR 333 in it running at 350. I've been running Super PI, 3dMark2003, and I've been running games all night. Not one lockup yet. I even did an XP repair install because I was too lazy to re-install all of my apps. This is SOLID!
I haven't tried the "barton upgrade" yet. I need to get some conductive ink tomorrow.
Does anyone know if this board is really supposed to allow you to adjust voltages? I don't see it anywere. The PCB is clearly marked "8.0" and the box says it SHOULD have the features.
In any case - not bad for 65 bones.
One more thought - the onboard sound didn't work and the board was used. I had to use an old Philips Acoustic Edge I had lying around. I'm too lazy to return or RMA it since it works fine otherwise. None of the boards at the Fry's in the City of Industry were new. I looked through the whole stack.
