Now it's disabled by the BIOS but since today I've upgraded the machine 5.5 to 6.3 though if under 6.XX series it worths or not. I've read for performance penalties under 5.XX series w/ HTT on. I'm not going to change to ULE (it's said to be better for HTT awareness). Please advice. If someone has a machine nearby please paste dmesg & top.
