Hi! I have an old Mac Pro (1,1 - 2006) with the 2,1 FW to support some CPU's that original 1,1 FW doesn't support. The SMC controller FW currently stay the same (1,1). My question is if I change the SMC FW too for the 2,1 Mac Pro can have a better stability on the overall system or by other way is better stay with the current 1,1 Mac Pro SMC. Thank you. Cheers.
