 Posted: Fri Jun 06, 2003 9:24 am Post subject: Problem: Hyperthreading with Xeon |
 |
|
Hi, me again 
I've not managed to enable Hyperthreading on my dual-Xeon Workstation, equipped with a Tyan Thunder i860 motherboard.
I have enabled APIC & Co like in the HOWTOs i found here in the forums... Hyperthreading IS definitly enabled in the BIOS.
Also it's strange that i have to set the Processor-Speed to 2Ghz in the BIOS to get 1,7Ghz recognized by the kernel... - That's shurely a problem with my BIOS!? Going along with that i wonder why the kernel detects a 100Mhz FSB, shouldn't the Xeon support 400Mhz?
Here's my dmesg:

The FSB clock frequency is really 100MHz but it supports four transfers/clock (quad-pumped bus), that's why marketroids are calling it a "400MHz" bus. |

I'm not sure how much luck you are going to have with those particular Xeons.
http://www.intel.com/design/Xeon/prodbref/
Check out the 3rd row of the table. The Xeons with only 256KB L2 cache don't do hyperthreading. That's why in dmesg it says hyperthreading disabled. Yes, it is very annoying. |
