Well I was at www.InsaneHardware.com and reading a review of the new Durons. They talked a bout EasyTune 3 (a windows based o/c tool for Gigabyte boards) and I thought I'd give it a go. My motherboard wasn't listed on the compatible list but I tried it anyway and bingo! instant FSB adjustment!
Now I can crash my system from the comfort of windows (I can do that without Easytune). I ran 3DMark99 as a check. My CPU scores at 100MHz FSB were 3450 at 112MHZ they were 3890 so the speed was real. I have a PII350Mhz on a BX motherboard.
Well for the owners of Gigabyte BX boards Easytune III works!
