[Mac Pro 1,1] SMC firmware

[cs.oyen]

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.

Yes I would recommend flashing the Mac Pro 2,1 SMC to your 1,1-2,1 if your up for such a task

it resolves several fan/sleep issues when running Clovertown CPUs in a Mac Pro 1,1 flashed to 2,1. I made sure to flash my Mac Pro 1,1 with the 2,1 SMC firmware when flashing the main Firmware to 2,1 Firmware (and installing clovertown CPUs)

Hi!

Thanks for your help, now have the 2,1 SMC too. I didn't notice substantial difference (like fan noise or other stuff) but if resolves some issues for me it's okay

One more question. What OS X version you recommend to use on this Mac Pro? I have done some hardware changes along with the CPUs, like 8Gb RAM, 1 SSD and 2 HDD and an ATI X1900XT. The latest version supported is OS X 10.7.5, I don't like much Lion, so in your opinion should install Snow Leopard or install an "hacked" version like 10.9? What you think?

Again, thank for your help

Cheers.
