Well, I've had my 7NNXP running for a couple of days now. I had some trouble with the memory settings, but once I resolved that issue, the board seems to be doing great. I played around with overclocking my XP 2200+ just a little...more experimenting than actually intending for a serious push. I was able to set the FSB to 150 with a 13.5 clock speed and get Windows XP to load up no problem. But, as soon as I put a real stress on the system, it rebooted. I increased the voltage to 1.75 and that helped, but eventually, it rebooted by itself again. As I had other things to do, I temporarily returned all the settings to "normal." I'll try again in the near future.
But, this board sure is fast! I crunch SETI@home and with the same CPU on this new board, I was able to reduce the time to crunch a single workunit by about 30 minutes. That's a lot!
Also, I tried using the included software that Gigabyte claims makes overclocking easier...my suggestion? Don't waste the hard drive space. It's a neat looking system monitor (prettier than MotherBoard Monitor 5, but does the same functions). But as a tool to make adjusting FSB, multiplier and voltage setting easier...well, there must be a trick I haven't discovered. LOL
