External Email - Use Caution

If you use non-ECC memory, it is a good idea to run something like memtest86 to ensure that it is error free (and return any sticks with errors to the manufacturer). ECC and non-ECC RAM should be similar assuming the non-ECC RAM doesn’t have errors 😉

External Email - Use Caution Dear Freesurfer community,

I am interested in building a PC with the goal of running Freesurfer (about 2000-2500 Euros). I have carefully read thishttps://surfer.nmr.mgh.harvard.edu/fswiki/SystemRequirements very informative webpage. However, I still have some questions and I would be glad if some assistance could be provided.

I suspect that a proper PC would be placed towards the workstation side of the spectrum, since from what I read in the above webpage, Freesurfer can utilize multiple cores and is quite demanding in RAM memory per instance.

What I would like to ask is whether ECC Memory is critical for this application or if the corruption coming from a non-ECC module has any significant effect on the end result. Also, any advice or suggestions about the system's buildup would be more than welcome.

Best Regards, Sotiris Michos
