Yea, I see that people misunderstand this quite a bit....<br><br>
No, I have a Quad CPU Tyan k8qs-4880 which has 4 Opteron<br>
CPU's. This is a Hyper Threading motherboard and shows<br>
up as 8 virtual CPU's. You can disable processors on the
board.<br>
These Tyan MoBo's are a hidden little secret. The throughput
increase<br>
between CPU/Cache, Bus and memory through HT is the best<br>
thing since sliced bread. (I picked up on these when Jay mentioned<br>
them about a year ago, and when I saw this board,I fell in love<br>
with it.)<br><br>
The other machine is a Totalcontrol Dual P4 3.2GhZ Proc<br>
with 2GB Ram at theplanet.com. I will get that one going, but<br>
it will take more time due to location, and I am only 1 resource.<br>
That box running RHES 2.4 with 2 3.2P4 HT is dual CPU with<br>
4 virtuals per the 2.6SMP Kernel.<br><br>
To get similar results I can disable 2 CPU's and it runs close<br>
to the Dual CPU P4... (A little better actually, because the
HT<br>
CPU's code even in 2.6 SMP Kernel is not all that efficient when<br>
compared to throughput increases on the Tyan MOBO with HT
Bus...<br><br>

</font><font face="arial" size=2>Yes unfortunately a 2.6 P4 is now a low

used all your ram your CPU is crying in most cases.<br>
