<br>
unganged = single channel. Each core gets access to a stick of ram.<br><br>Is this correct?<br><br><br>------------------------<br>

<p style="margin-top:0px;margin-bottom:0px;margin-left:0px;margin-right:0px;text-indent:0px;">Yeah, it's a wonderful thing AMD calls "unganged" mode. I have 8 GB of ram in my server and the motherboard has enabled "unganged" mode to be more efficient. CentOS only recognizes 5.8 GB of ram and I cannot turn off unganged mode.</p>
