Can somebody help an OC newbie?

Great info on this board! I just picked up a Barton 2500+ (sorry don't have stepping right now) and 2x256MB Kingston PC3200 for my Leadtek Winfast K7NCR18D Pro. I'm having troubles getting any stability out of any noteworthy OC.

The machine spontaneously reboots itself in Windows @ 190FSB, 1.8v. I'm just using stock cooling for now, but I have a well ventilated case. CPU idles around 40C, under load gets to about 49C before it reboots. I have a BIOS alarm set to go at 50C, which I have yet to hit. To me that seems like some reasonable temps, but its not stable at all.

PCI/AGP are locked. Mem should be able to handle anything up to at least 200/400 I would think. PS is generic 400w. I'm getting some better cooling for the CPU but it doesn't seem like heat is my problem...

What about my mobo? It's supposed to support 400Mhz DDR Ram, but is it possible that it doesn't support CPUs running at 400Mhz FSB?

I'm not familiar with your m/b. What bios features does it have for o/c'g?

It's got pretty much everything... I think. Like I said I'm still pretty new to this but I'll try to run down the BIOS features:

1Mhz FSB increments
1Mhz AGP increments
AGP/PCI clock lock
Lots of FSB/Memory Speed dividers
Full memory timing control
AGP Voltage Adjust
CPU VCore Adjust (1.3v - 2.0v, .025 increments)

It appears to have a lot of OCing features...
