Can someone with high (150)FSB speeds tell us your BIOS settings?

I'd be very appreciative!

What are you running at now? I see the multiplier and fsb on the 1800 but there is none on the 1900. Try lowering the multiplier and moving the fsb up as high as you can stable. I too can run at 11.5 at about 145ish. But at 11 I can run with the fastest settings at 156 stable (crucial ram). I backed it to 155x11 and all is happy. I found that at 10.5 or lower I could not raise the fsb any higher, so I went to the highest multiplier that would support the fsb.
