got latest bios, no improvement.

This is the one made for Presoctt and performs better than the previous large copper base design.

Surprise on the temp you are getting.

Is there a CPU FSB strap setting in your BIOS?

When I use my IS7 on P4 2A, I picked 667 FSB setting to "fool" the board to clock over 3.34 ghz. In your case, I believe if your board has CPU strapping, you have to pick 800 to go over 200 FSB.

yes, I picked 800 (200) fsb , and in the bios I could set fsb up to 400 (1600), but from the moment on I set it over 200 fsb, let's say 202, then I get on my bootscreen 101 fsb...

thus 300 fsb = 150 on boot,
and 400 fsb is 200 .....

also when I reset the board, en set it to fsb 166 or 200 by jumpers, to fool the board, the fsb is set to 150....

133*4 = 533
166*4 = 664 or 667
200*4 = 800

Not trying to be funny... just for illustration.

Have you tried to set at 667? Or, does the BIOS provide this option?

tried everything.
