I am currently using 905 BIOS and seem to be able to run much higher FSB (415), has anybody else tried for higher FSB with the 905 BIOS? I am having voltage control problems even at stock freq. I only seem to get 1.8v,2.28v and 2.5v on my DDR2 mem voltage and same sort of thing with the CPU volts. After booting and checking with CPU-z and nTune I'm running at 3308Mhz. They also show that it is set at 425 X 8. Everything appears stable as I can run 3DMark for 15 loops and run Crysis for hours , all settings high and 4X Antialiasing @ 1289 X 720. I'm a bit leery about trying higher FSB even though everything appears normal. Also running very quiet! Can anybody confirm whether this is within normal range of o/c?

SYS 425 X 8 (set) 415 X 8 (actual) 1.4v HT X2 Ram set to PC 400 3,3,3,15 2.5v
Ran orthos for 5hrs at priority 5 and then restarted at priority 10 and left it overnight. My own mixed bag of simultaneous programs had also ran stable for hours! The stability is the concern. If it is running this stable at near stock voltages (except RAM ) I would normally be compelled to start cranking it, but when the system is this far out of spec and the voltage issue I am a bit leery and would like to know if there are more people getting into this range. After installing 905 BIOS the first time, I tried to set the memory voltage lower then the 2.5 I was getting on auto. The voltage first went down to 2.28v, set at 2.45v and then 1.8v, set at 2.35. I then had to reinstall slower mem for a restart ( OCZ titanium wont start at 1.8v on this board ).After restarting I was limited to 2.28v no matter what setting. Thats when I found out I could not easily downgrade BIOS. I reflashed 905 and back up to 2.51 on Mem. It is hard to say which BIOS settings will take or not. This high FSB into evil INTEL territory has me amazed and may just have to jump in and take a risk. Sorry about the long post but like I said I would appreciate any info from others trying high FSB before proceeding.
I have been building and overclocking since '93 and have never seen a system this far out of spec!
