I assume you get your chip from divineo ? try sending it back , i have spoken to them at lenght regarding the issues with these chips. There should be no problem returning the chip to them.
If you buy a game like Splinter cell and a Xbox Memory card you can install a softmod easily. Or do what i do and solder in a headerpin , ground d0 and plug a duox2 chip onto the headerpin. Boot AID 2.11 final and install a softmod to the hard drive and then remove my duox2 and remove the link from d0 to ground. Now the xbox is softmodded and if i ever have a problem i can just ground d0 and plug a duox2 ( or similar lpc modchip ) onto the headerpin and boot AID again. If you can't solder then you can even use a Solderless adaptor to make it solderless and painless !
