BSel mods for Intel Xeon X54xx CPUs

post #1 of 3
Thread Starter 
I am trying to do a System clock mod to an Intel Xeon X5460 to increase the system clock from 333Mhz to 400Mhz. I have read a lot of people talking about it ; but can't seem to find anyone who will actually share the info/pictures on how to actually do it. I have found the datasheet for the Intel Xeon X54xx processors and identified the correct lands (BSel0, BSel1, BSel2) to accomplish this; but, I don't know what to do to the lands. Some mods take conductive pens and connect two or four of the lands. Some mods take electrical tape and just insulate the lands.

Can anyone out there in internet land help me?

I wonder if this is what you need. I have never modded a 771 CPU, but i've done several 775's, and AFAIK, the BSEL modding stopped at 333 MHz for the FSB, especially since only one CPU (QX9770) got to 400 MHz since the bus was 'necked enough already, before the change to QPI.

Thank you my friend for responding to my post. Any information I can add to my knowledge base of BSel mods is welcome. Is there any chance you could provide a link to where you got this information from or possibly provide a higher resolution version. It is too small too read and when I download it and try to enlarge it, it is too blurry to read. Thanks for your time in this regard.
