Xeon it is then. As for the rowhammering attack as far as I know ECC RAM is not vulnereable to that. t's a shame that the more powerful Xeon CPUs don't come with a built in GPU, I'll have to make do with a current one. Added benefit here is that pretty much all Xeons support technologies necessary for Qubes 4.0 compliance. Wonder why they aren't more popular among desktop users. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
