This purchase is for ONE Coolrunner Rev C board/chip.  These are NOT Team Xecuter products, but rather a duplicate made from the same design.

This chip is used for diagnostic/repair work on the Xbox 360 console.  


Purchase includes:

-CoolRunner Rev C Chip

-Adhesive pad to mound chip

-Phat/Slim Wire Pack

** The CoolRunner Rev C come BLANK as default and requires programming.   I offer the option on the right to program the RGH 1.2 "21" timing file as I find that one gives great performance on both Falcons and Jasper motherboards.  Additionally I offer the option to program the Muffin 7_1 timing file which works great for Trinity installs.

You absolutely can program it yourself with any number of possible programmers on the market.  Programmers that could be used include the JR Programmer (v1 &v2), Super Nand Flasher, Squirt Slave programmer, or Nand-X.

*We've had a lot of folks buying a Nand-X and still ordering their chips pre-programmed. If you order a Nandx just program them yourself and save yourself the $1 fee we have added. 

Here is the download file pack for the muffin timings: 

Here is the download file pack for the RGH 1.2 timings:


This product requires professional installation and should NOT be attempted by amateurs.

Due to the high risk of user error the Rev C chip is sold here with absolutely NO WARRANTY.

There are NO RETURNS ACCEPTED under ANY circumstances once the item has been touched by a soldering  iron.

Purchase of this item does not entitle you to me supporting your own DIY install!  I have lots of videos you can follow, but I will NOT promise one on one support for installs!
