Memory Ratio on P4B533-E

Is there a way to change the options on the cpu/memory ratio? I am currently running at 170 FSB and my options are 1:1 or 4:3. I would like to have a 3:4 option. Is this possible? That option existed below 133 FSB, does it come back at some point?

Thanks.

Yes, 3:4 is an option but you have to do a little trick. Read this thread, it gives all the details. I've been running my P4B533E at 150FSB/DDR400 for the last eight months using this method.

Thanks for the info. I'll try it out.
