<DIV>i disabled it just to see if that's why its causing the system to display 4 cpu.</DIV>
<DIV>on the RAM issue disabling HT shows only about 6k used, i don't know how it consumes much with HT enabled, might be it doubles?</DIV>

<DIV>Hi Gurus,</DIV>
<DIV> </DIV>
<DIV>I just built an ibm x345 with 2GB ram and 2xCPU(xeon) running Linux ES 3.0 with kernel - Linux version 2.4.21-9.0.1.ELsmp. Apps running are httpd(stock), sendmail and bind. </DIV>
<DIV>This is not yet launched on production so basically this machine is idle. I ran /usr/bin/top and it gives me these output (sorry for the display):</DIV>

<DIV>My concern is how come it shows 4 cpu's and the memory used way the total. Does that mean when I go to production this machine will need more memory?</DIV>
<DIV> </DIV>
<DIV>Is there some settings/tuning parameter I should be aware of?</DIV>
<DIV><BR>Thanks for any info.</DIV>
