<p>You know.. What i am going to tell you will not sound good. My
board was Sabertooth 990-fx R2. My little story is that at first
it seemed to run ok (with r9 270X card). I sinked enough hours to
titanfall and it was great. After good period of time of non-usage
(as board was in warranty service and eventually swapped to brand
new board), multiple kernel updates and migration to archlinux i
no longer could get it running as fast. Now i do not know if i
just did not feel slowness initially and it was always there or if
something changed, but i know for a fact that testing older kernel
releases did yield a little bit better performance (enough that i
could notice). So i moved back to dual-booting due to performance
reasons. In the end combination of this and r9 270X constantly
causing entire PC to go down with a red screen i simply swapped
hardware for intel x99 + nvidia gpu. Such is sad story of mine..<br>

depending on how kernel modules are compiled
config go to different places.</div>

<p dir="ltr">Hi all,</p>
<p dir="ltr">I was wondering if
anyone is experiencing this

<p dir="ltr">I am using
ArchLinux with latest stable
Kernel, qemu and libvirt.</p>

starting to spin quite soon.</p>
<p dir="ltr">Can anyone help

reports with about 3%
