OK, here's the deal. I've got a 1.6 mobo and am trying to put an X3 in it. I've done this about 15 times or so, so i'm not new to this. The problem is that besides fragging, I know that when the chip is in and the alternate 5V is not connected, the chip will always be on. Mine is not. If the chip is plugged in & alt. 5V not connected, the 5V & 3.3V lights on the chip don't come on. When I connect the 5V & turn the xbox on, it frags & both 5V & 3.3V lights are on like they're supposed to be. Here are my multimeter reports.
XBOX on, modchip not connected (ie readings off the pins)
1 - 1.63V
2 - 0
3 - 0
5 - 3.27V
7 - 3.32V
8 - 3.32V
9 - 3.32V
10 - 3.32V
11 - 3.32V
12 - 0
13 - 3.33V
14 - 3.33V
15 - 3.33V
XBOX on & FRAGging, modchip connected (ie readings off the back of the X3)
1 - 0
2 - 0
3 - 0
5 - 0.13V
7 - 3.32V
8 - 3.32V
9 - 3.32V
10 - 3.32V
11 - 3.32V
12 - 0
13 - 3.33V
14 - 3.33V
15 - 3.33V
I checked everything in relation to what I found here:
http://www.xbox-scene.com/articles/lpc-diag.php & everything looked ok except pin1 which should read 1.6V.
XBOX works fine with the chip desabled.
Anyone have any ideas or help me on this? Please.
P.S. I should also note, that I can boot up to the backup BIOS by holding eject & power on. I can also boot to any 256K bios by toggling the external switch. However, if I toglle to a 512, 1MB, 2MB BIOS i get the FRAG. I can flash when booting up to the backup BIOS, but then it FRAGS.
P.P.S I have tried 3 different X3 chips and they all do the same thing, however work fine in my other XBox, so it's not the chip.
