do latest MacBookPros support ECC memory?

Rate this Message:
Hi,
I recently got a new MacBookPro. In the system profiler, under Memory Slots (in the lower panel), it says ECC: disabled Does this mean that I have ECC memory and there is some switch I need to throw to enable it? If so, does anyone know how to enable it (assuming there is no downside to this)? Or is this just an obscure way of saying that I have non-ECC memory?

Macs have never used or needed ECC memory. Used to be they wouldn't even run with it; I suppose it's possible current models will run with it but still not use the feature. -- Macs R We -- Personal Macintosh Service and Support in the Wickenburg and far Northwest Valley Areas. http://macsrwe.com _______________________________________________ MacOSX-talk mailing list MacOSX-talk@... http://www.omnigroup.com/mailman/listinfo/macosx-talk |

Thanks for confirming. By the way, on my MacPro, this same field says ECC: enabled, so as you say, it is supported by some Apple hardware.

I also thought that apple hardware did not support ECC memory, but apparently it does now, since that same field on my MacPro says ECC: enabled. _______________________________________________ MacOSX-talk mailing list MacOSX-talk@... http://www.omnigroup.com/mailman/listinfo/macosx-talk |

While most Macs in the past never used ECC memory, it is patently false to say they never needed ECC memory. ECC memory is ALWAYS a good idea. Being a Mac does make it immune from the laws of physics. Macs are great but not that great. > Used to be they wouldn't even run with it; I suppose it's possible > current models will run with it but still not use the feature. MacPros at least will use it and have for some time. Saved my bacon too. I had a problem with a memory riser card in my MacPro which was causing bit errors but the ECC facility meant I got a warning instead of a crash. _______________________________________________ MacOSX-talk mailing list MacOSX-talk@... http://www.omnigroup.com/mailman/listinfo/macosx-talk |

The last, late 2005, Power Mac G5 also uses ECC memory. -- Larry I.

My Mac Pro most certainly uses ECC memory, and my System Profiler says ECC: Enabled. -- The real world was far too real to leave neat little hints. It was full of too many things.
