Hi
Can anyone help me here:

a1 28nm module

Cgminer:

Utility showing half the speed of all the rest of the other modules.

Running at about 20-30% hardware error

Was missing a capacitor. I have soldered one back on.

What should I be looking for? Would this maybe be poor quality of capacitor?

Or should I be looking at something else completely? What does the utility show/measure between?

Thanks in advance
