So, from what I can see, the soldering needs some work. You need to trim the wire leads a bit, that is how you short out boards, and burn CPUs. Also, why do you have the stby_clk wire going to multiple spots on the bottom of the board?

Is that a genuine CR Rev. C?

Which hack are you trying to use?
I doubt it is genuine, but it is hard to tell with the current pictures. lol. From what I can tell, he is attempting RGH1.2, or R-JTOP. lol. I didnt see any jtag wiring, so I would assume RGH1.2.

It is easy to see it's fake? No idea what you guys are smoking!

OP clearly cant solder by the clk repair, the CR wires are woeful too.

I am using an alternate stbyclk as I have messed up the original

I couldn't find a legit Coolrunner that ships to Australia

Yes right 1.2

What leads do you mean? Sorry I'm new to this.

So what do you guys think is the cause of the green light? JUst soldering or is there another problem.

a bridge can cause the green light to appear.

desolder each wire from the CR until it disappears, so you can understand the issue.

I was talking about all of the exposed wire. if it touches another point, or the metal case when you put it back together, it can and/or will burn out the coolrunner, and/or the motherboard...... Especially the CPU_PLL_BYPASS wire(Wire A). So trim all wires, so that there is not any exposed wire, that is not in the solder point. As for the other question, I was talking about the orange wire, that goes from one point on the bottom of the board, to another, and then to the coolrunner.

ok thanks and the orange wire is an alternate stby_clk wire because I messed up the reccomended one

If you burned out the point on the top, and are using this as a repair, there should be a resistor(I dont remember the value off the top of my head, possibly 22ohm), between the points on the motherboard. So, if you were to remove the wire from the coolrunner, and leave the repair wire, that is where the resistor would go. ;)
