Mac Pro 3,1 Uncorrectable Fbd memory error detected

Dear Community,

I am running 10.10.2 on my early 2008 Mac Pro 3,1. I have recently been experiencing a sudden reboot, at least once a day, when watching video. Seems memory related and not sure what to do.

Below is the report shown after start up. Please help me decipher the meaning and guide me toward next steps for discovering a solution. Many thanks!

First go to About This Mac in upper left after clicking on the Apple icon and then to System Report and then to memory. Does it say OK by all sticks?

If so try reseating those sticks. If still listed as not OK then remove them since they appear to be bad.

If they say OK then reseat all sticks. If still problem remove a matched set and try again. If still problem replace those sticks and remove another set. Repeat until you no longer have the problem

Thank you Illaass. The system report does not indicate any problem. I found a recommendation to run memtest. I did so 3 times and the results were clean. http://osxdaily.com/2011/05/03/memtest-mac-ram-test/

I will now try the alternating set removal you recommend.

Sincerely, Liko

Mac Pros use ECC (error correcting code) memory and thus bad memory usually passes MEM TEST since most errors are corrected

Hi lllaass,

This screenshot is from my system information page. Does it look correct to you? Thank you!

Yes OK if the capacities are what they should be and B DIMM 3 and 4 are really empty. Sometimes suring the startup RAM test a DIMM show will show empty if the test showed it bad.

This is what a BAD one will look like:

thanks to anandtech.com for making and posting this graphic.

Correctable errors will start to accumulate in a Bad module, and eventually you will get an error that can not be corrected.

Keep in mind that this display is a snapshot, and is not updated unless you choose REFRESH off a Menu or invoke the report again. (which you should be doing, about every half hour, until you find the bad module(s).

Also keep in mind that temperatures inside the box will strongly influence memory errors.

Thank you so much for your assistance. Although the snapshot I posted did not indicate an error, I did find something on the quick "memory" tab in the About This Mac main screen. It indicated a problem with one of the DIMM. I reseated that pair of DIMM and all working well so far.

Thanks again, Liko Puha

Over t he years those that had an error, reseated FBDIMM, generally was a temporary fix.

I would still look into buying a pair of FBDIMMs.

In these Macs, reseating the DIMMs usually does not solve the problems for very long. You will soon be back where you were.

You should find a source of inexpensive FBDIMMs, qualified to run in the Mac Pro, in your part of the world. Where are you located?

Thank you for the recommendation. I currently reside in Santa Rosa, California. I have purchased memory online from Macsales in the past. Any other recommendations?
