8 cores shutting down

[Jeffmcohen]

Sleep is turned off. I did a reset for the power and the restarts have quit. Final Cut still quits upon long renders though.

Does it quit in the same place every time? Any chance that it quits when it gets to a still frame that’s CMYK instead of RGB, or that is particularly huge in size (over 25 MBs or so?)

Wow, I had a bad feeling when I started thread this was a bigger problem than our two 8 cores. Is it only 8 cores, I realize mac books have had this problem but do the 4 core Mac pros have this problem too?

We are on conditioned power, we’ve gone straight into the wall, it doesn’t seem to be tempeture related, it happens first thing in the morning. It is certainly render related with FCP 6. We have another 8 core encoding with compressor and it never shuts down with heavy encoding. If it’s FCP 6 related why in the world is the entire computer shutting down?

Try resetting the power Management Unit (although it’s not called the Power Management Unit in MacPros, I can’t remember what it’s called, something like the SMC) and see if it cures it like Jeff did.

Power management? SMC? We certainly have the sleep turned off and all energy saver things turned to never

Thanks for the response but I’m not where to find this

Let me dig it up for you. It’s a tiny button on the inside of the Mac on the motherboard.

I’ll get it, stand by.

Looky here, it was the SMC (System Management Controller)

A Mac Pro should only get up to about 70c or 160F, any higher there might be a problem. I do know the case can handle quite a lot of heat, the powermacs got up to 180F-190F. The new intels though are much cooler than the PPCs, and use less electricity.

If you need to you, you can always reset the SMC(another option I forgot about): https://docs.info.apple.com/article.html?artnum=304123

This normally does fix or help much, but in your case it might. Every time I have a computer that shuts down like this, Apple always says I need new parts.

Great info, we also just used the smooth cam plug in which seems to be a heavy render but I believe it’s actually coming from Motion not like a heavy FCP render which causes the shut down.

Thanks for all the great feeback! If any or all of it works we’ll certainly post ASAP.

Quits in all different places. Just long renders.
