amd microcode

[vsreeser]

Do I need to install anything concerning the amd microcode in Kubuntu 14.04? Running an AMD Phenom II X6 1065T proc. I see posts about it being bad and good

I'm on intel

looks like 2.2 is newer that what I have ............

wander how dangerous this may be ,,,,,,,?

I'm on AMD with 2.0 Come to think of it, only my 2 slower laptops are Intel. Wondering how dangerous installing 2.2 would be. Well, I made an image last night so I guess I'll go ahead with it. If it blows up, I'lllet you know on the other computer.

[vinnywright]

well you go with it then

sudo apt-get install amd64-microcode

good luck

virgil@reeser-dad:~$ apin amd64-microcode

I guess I should have run a benchmark or something. Hard to get X6 machine to load down much. Hardly ever see cpu usage (overall) about 5%. So, not sure if I just accomplished anything

On Athlon 64 X2

virgil@reeser:~$ dmesg | grep microcode
[ 1.643689] microcode: CPU0: patch_level=0x0500010d
[ 1.643812] microcode: CPU1: patch_level=0x0500010d

[60029.780035] microcode: CPU1: new patch_level=0x05000119

X2 used to run about 15% total cpu usage. After microcode install and reboot, it is running about 4%, so there may be some benefit for lower core processors. For reference, the X6 runs at 2900 and the X2 at 1400. Info from conky. Not sure why temp doesn't show on either, but I'll figure out and fix that eventually.
