Almost. Much to my dismay, the 4 stick testing went well but the
BIOS screens occasionally hung during reboot through the course
of the day. I finally just pulled the 4th stick and went home.
I've modified the rc3.d/S99local* script to just reboot every 10
minutes and compile a kernel and modules in between. I thought
I'd heat things up a bit piping urandom into /dev/null as well.
I've got other fx-62 boxes running the same mainboard with all 4
ram slots full, but those are Corsair ram @1G each - the ram timings
are different as well; 5-5-5-12 for the Corsair and 6-6-6-18
for the GSkill. Maybe the GSkill ram just isn't up to the task
running Dual channel. I have the weekend to play with it so maybe
I'll try two sticks in Dual Channel for a while and see what happens.
I'll post kernel compile times between the 3 sticks in single channel
and 2 in dual channel :)
