hyperthreading

[Blind_Arrow]

well, Dual CPU (means 2 CPu in physical, not HT based 2 CPU) are for servers. so servers require Reguistered DIMMS, as Major said. they are slow, yes they are.

but you can get 1 Intel P-4 with HT (means showing 2 CPU where 1 is virtual), and it takes Un-registered DIMMS. (as in my case, HT on Un-registered DIMMS)

and where games. programs are concerned, there are programs that do support multi threads (thats y HT enabled CPU's are faster), like photoshop if opened on 3.6 (Non-HT) and at the same time 3.0 (with HT), then the 3.0 will ope it faster, even its 600Mhz slower than 3.6.

I am actually AMD fan, but this time i made Intel HT just beczause i'm Photoshop user, and many other software that support multi threading.

Ah, how can I find out if my is on or off? I have not messed with anything. Can someone give me a quick direction how to get into BIOS and turn it off or on. Thanks

 

[Blind_Arrow]

ah, u have same setup as mine (almost)

do this:

press alt+ctrl+del

and select performance tab,

the upper graph is for CPU (if u see 2 segments in CPU graph, then it means ur HT is working)

if the graph is as same as Page File (means only 1 segment),

then enter into BIOS and you'll find there HT [enabled/disabled]

Wow our computers are alot alike! *Looks down both lists* Now I know exactly who to go to for computer questions!

I saw two graphs on the "upper" side so I think that is what you meant by HT, so I think I am enabled which is good. While I was in Win Task Manager though I saw that I had 39 programs running. Is this ok? Way to much. Looking down the list I don't even know half of them. Only a Quarter of them look familiar? Any ideas should I take a screen shot or something to give better visual?

its perfectly normal:

I have 40 running (even I'm only running only browser at this moment)

even if u install windows for the first time, you'll see around 30+ programs running already, they are memory controllers, systems controlelrs etc etc., and as you'll install things that start-up with system start-up, this number will increase

so be worryless.

Well i am on a 2.4 P4 512 right now, and with 3dMark03 it says Hyperthreading is:

Availiable - Not Enabled

And the bios has no option anywhere to enable or mess with hyperthreading at all.

Is there someway I should be updating the Bios?? I've never done it and am sceptical, unless its just like a video driver....(input needed).

Oh yeah, if it matters, I have socket 478.

 

[Blind_Arrow]

Alex, not every 2.4 came with HT,

are you on 2.4C series? as in 2.4 clock, this is only CPU that came with HT. else higher versions.

Oh! Um check your PM Blind Arrow
