Apologies for Double Post (re: Hyper-Threading)
Hi, I apologize for the double posting of my question about getting Hyper-Threading to work on my new hardware. The second message includes a bit more information and omits the P.S., since I've now subscribed to SuSE-linux-e. (The long delay in the first post showing up led me to conclude that only subscribers were allowed to post.) Randall Schulz

Randall, I think if you check, the HT Pentium4 cpus start at 2.8 or 3.0Ghz, so my first guess would be that you don't have a Hyper-Threading cpu in your machine. Lee -- --- KMail v1.6.2 --- SuSE Linux Pro v9.1 --- Registered Linux User #225206 I do everything my Rice Krispies tell me to do!

Advertising and Marketing are wonderful things Felix. ;o) Check Intel's actual specs though. Lee -- --- KMail v1.6.2 --- SuSE Linux Pro v9.1 --- Registered Linux User #225206 I do everything my Rice Krispies tell me to do!

My understanding was that hyperthreading came out with the 800Mhz FSB, as your link describes. And yes, these are/were avaiable as 2.4Ghz chips.

IIRC, there were a number of chips that set the ht flag, but only have 1 logical processor in them. I had a computer like that at work. :-( -John

And now I have one at home. It's no big deal, but why in the world does the processor set that feature flag if it doesn't actually have the Hyper-Threading circuitry?

Long time ago, I read an article that some P4 series of HT and non-HT CPUs were manufactured the same way. Later in the production, HT was disabled in non-HT CPUs. If the article is right then you have the HT circuitry in your CPU but you cannot activate it. -- A.M.
