Re: PAE or not PAE?

No, you also need it on machines with 4 GiB of RAM and remapping capability, in order to use the part of the RAM which is remapped beyond the 4-GiB boundary due to the "PCI hole". Usually the remapped memory amount is about 500 MB, but I have seen machines remapping 1 GiB or even 2 GiB, leaving only 2 or 3 GiB of usable RAM with a non PAE kernel.

Note that the non PAE kernel in older Debian versions up to Jessie lacked multi-processor (including multi-core and hyper-threading) support.


Thx for the clarification.
