DL740 and Hyper-Threading

Travis Finch — Sat, 17 Jan 2004 14:11:12 GMT

Hi all,

I have 2 fully populated (8 processors) DL740s running Windows 2003 with Hyper-threading enabled. In Windows, one machine lists 8 procs and the other 16. Hyper-threading is indeed enabled on both, so why the disparity?

Thanks, Travis

Hello Travis,
Please make sure that the BIOS is uptodate. Upon reboot go to F9. In advanced features just disable the HT save and exit. Upon reboot go back to F9 and re-enable HT. See if this makes any difference. Here is the link to update the BIOS just in case you need it.

I checked the BIOS on both servers and they are the same which is up-to-date. I tried disabling and re-enabling HT to no avail. Just to confirm, I should be seeing 16 in Windows, correct?

Hello Travis,
What happens when you disable HT in both the servers?? What's the end result??

Thanks!!

Check BIOS configuration, OS Config.
Set this option to Windows 2003.
