-Subject: [PATCH 133/143] mainboard/asus/kgpe-d16: Limit HT speed to 2.6GHz
-
-The CPU <--> CPU HT wiring on this board has only been validated
-to 2.6GHz. While higher frequencies appear to function initially,
-and in fact function when only one CPU package is installed, dual
-CPU package systems will lock up after around 6 - 12 hours of uptime
-due to presumed HT link errors at the higher (>= 2.8GHz) HT clocks.
-
-If applications are not being used that stress the coherent fabric,
-then the uptime before hang may be much longer. Users attempting
-to overclock the HT links are advised to "burn in test" the HT links
-by running memtester locked to a node with no local memory installed.
