Having started with a soft mod, then TSPOP and finally installing an open xenium with the help of this great community I've decided to go to the next level. I've received the RAM below in the post today and just checking if this will be okay to use for upgrading to 128mb on one of my experement xbox's? I've also read somewhere that you can install one chip at a time and test it through the the one of the BIOS's that is specially made for this. Then I can continue to add more after each successful chip install!!!
