P4 Hyperthreading problem

[bubbles]

I have a P4 2.8g with XP Pro.

In Device Manager it lists 2 identical processors under the processors tab, but in Task Manager it only shows one CPU graph.

Is XP using hyperthreading? I think it used to have 2 graphs in task manager.

Hyperthreading is enabled in the BIOS.

Any ideas how I re-enable it?

Open task manager, click on "performance"....click the "view" tab.... go to "CPU history"..make sure "one graph per CPU" is checked and not "one graph, all CPU's"

That option is already selected and it still has one graph. I did some searching on other forums and someone said do a repair install to get the HAL or some crap re-enabled so I will try that when I find my disk.

Also try updating your chipset drivers?

Is there a /numprocs=1 switch in your boot.ini?

i would not change the ini file, it doesnt matter wether it is in task manager. the cpu manages that way better than windoz. windoz has sucked at multi processor ( evn ht) ever since time began. intel know this and so (low and behold do amd) hence they put instructions in the proc, so if it is needed it will use the HT. and honestly do u ever assign something to the HT (other core... yes i know its fake). have you tried reinstalling, tho if you do may i suggest a slip streamed xp install disc with service pac 2?

Excuse me, but this is absolute nonsense.
In fact, Windows XP is the first and only (excluding Vista) HT-aware OS available. It has a specifically optimized scheduler for HT which avoids any cases where HT would be slower than no HT. Other OSes just treat a HT-system like a dual-CPU system, which causes the system to be slower in certain cases.

What you're saying about instructions is nonsense aswell. Instructions don't do anything if the OS or application doesn't use them.

So stop spouting your biased misinformation please.

Thanks Scali2, saved me from typing a response... Oh and Easykill1978 fix your sig...its over the line limit...

Of course it does!

I can't make much sense of the rest of your post; from what I can tell, it's complete drivel. Which specific instructions are you referring to, for example?
