xicat487 Posted June 2, 2020 Report Share Posted June 2, 2020 Came across a X3 box with LCD ad BIOS bank switches. The problem is the clock Cap leaked. I want to move it to a known good motherboard but the LPC wiring to the chip differs from this link. https://team-xecuter.com/x3/tutorials/x3pin1015.htm Is this the most up to date install manual for a X3 chip ?

Ging3rguy Posted June 2, 2020 Report Share Posted June 2, 2020 What version board are you going to use? http://x3.bustedchain.com/installation.html Quote Link to comment Share on other sites More sharing options...
xicat487 Posted June 2, 2020 Author Report Share Posted June 2, 2020 v1.0 I found your link before but the chip install link HTTP is dead. I believe the link posted is supposed to be the reference and just wanted to make sure. team-xecuter.com vs teamxecuter.com the - is the difference Quote Link to comment Share on other sites More sharing options...

How's the wiring differ? All pins of Xbox LPC ports get connected to the same signals. For 1.6 Xbox's, you have to reconnect the signals to the pins since MS removed the signal connections to them. There's another tutorial showing you how to install the X3 modchip into a 1.6 Xbox https://team-xecuter.com/x3/tutorials/x3pin16.htm Quote Link to comment Share on other sites More sharing options...
xicat487 Posted June 3, 2020 Author Report Share Posted June 3, 2020 In the instructions it mentions the entire LPC is used minus pins 4/16. This install has missing pins 3/5/12. The chip works flawless in this way just not sure how. Quote Link to comment Share on other sites More sharing options...
KaosEngineer Posted June 3, 2020 Report Share Posted June 3, 2020 Pin #3 LFRAME# - I don't believe it's used by X3 modchip (MS removed this signal's connection from the MCPX chip to the port for 1.3-1.5 consoles) Pin #5 LRESET# - ??? I don't think the modchip needs a connection to this signal. Pin #12 Ground - same as pin #2. Ground is ground once you have one connected you don't really need another for the modchip to work properly. Pin #4 Not present on 1.0-1.5 consoles (1.6 power control signal - ground and the console will turn on / off - no connection necessary for the modchip to function) Pin #16 SERIRQ signal only present on v1.0 consoles. Not needed for modchip operation. Edit: Pin #15 3.3Vdc - same as pin #9. 1 Quote Link to comment Share on other sites More sharing options...
xicat487 Posted June 3, 2020 Author Report Share Posted June 3, 2020 Thank you for the technical explanation of the mentioned pins. I was erroring on the side of caution when the latest install revision did not match. So basically the unused pins must help with retention for X3 to the LPC.
