how can i enable hyperthreading on non hyperthreading cpu???

[samiii]

i just ran pcmark2005 on my 3yr old non-hyderthreading cpu......its cpu details tell me available hyperthreading but disabled.....how do i enable it???????

 

[RB9269]

Erm? What processor is it? I know i tried for ages to enable hyperthreading on a CPU that had hyperthreading disabled but couldnt get it to work. This was because the hyperthreading parts of the cpu had been cut off from the rest of the processor meaning that i would have had to have made some modifications on the CPU itself.

You might actually have a hyperthreading enabled CPU but the hyperthreading is turned off in the bios, or the motherboard may not support hyperthreading.

Need more info

as far as i know you can't. Thought it was a hardware thingy. and i have yet to here of software hyper threading...

just wait bet you in 30 secs sum1 who knows will post

No there is no software hyperthreading.
However, you might have a CPU which supports hyperthreading, but the feature is disabled in the BIOS of your motherboard.
It might be a matter of just enabling it in the BIOS, flashing a newer BIOS, or just being out of luck

its cpu details tell me available hyperthreading but disabled...

oh you mean pcmark 2005 says you have a hyperthreaded cpu, but it is disabled... oh. go into your bios and fiddle around with the settings (if you don't know wot a setting does it is a good idea to leave it alone).

in future you should give your system specs - helps the ppl figure out your problem

hyperthreading is pants anyway. leave it disabled. but hey, thats just me.
if there isn't an option in the bios to enable it, you're out of luck. sorry, your mainboard probably doesn't support it...

May be the problem of software......

ummmm, just so you know hyper threading vs non-hyper threading on a 3 year old cpu.... hyper threading kicks ass.... it increases cpu performance a shit load... however i am not too sure with the dual core cpus (i think it is the same but in a more complex way or sumthing, i don't wanna pull out my text books to you will have to trust me.... ).

Dude, Your The GOD of Hyper threading, Even the seasoned pro's didn't know that Hyper threading Is some hot Complexly enabled in Core 2 Duo's Or at least the Pentium D's 8O .

galespurehoney for a 3yr old System, Hyper threading vs Non-Hyper threading in you computer, Hyper threading will very much help out. But it's no where near actual Dual Core and not a Light year within Reach of the Core 2 Duo's.

Actually, if i remember correctly, the only dual core CPUs with Hyperthreading (for a total of 4 threads per CPU) were the Pentium Extreme Edition.
There is no HT in Core2.
Anyway, on a Pentium4 CPU, HT gives a performance boost in the range 0-10% application dependent (sometimes it even produces a performance hit), not too shabby but you don't miss out too much.

Just for a little light reading, check this out: http://www17.tomshardware.com/cpu/02q4/021114/p4_306ht-21.html

I turned off the HT capabilities on my work computer because the programs I use actually took a performance hit.

CPU-Z says p4 2.4 code name NORTHWOOD..... 1 core 1 threads........mobo is intel d845pebt2.....cant find any option in bios.....i read somewhere only engineers cud enable hyperthreading in that processor.....

Pour Mt. Dew on your motherboard. If it works for 3 year old humans, why not 3 year old computers?

From what I remember, Lightwave renders on my PC were about 30% faster with hyperthreading than without; however it's a long time since I tested it.

If they can do that maybe they can enable the 7th and 8th cylinders on my V6.

Intel were including the hyperthreading technology in Pentium 4s for a while until they actually marketed and enabled it and that wasn't until the Pentium 4 reached 3GHz (maybe with the Prescott core). This is why some utilities might recognise the technology but you won't be able to enable it.

Plus you did also need the right chipset if I recall correctly, so you might be out of luck on 2 counts.

Northwood 3.06 has hyperthreading enabled: I believe that was the first with official support, but earlier Northwoods had hyperthreading hardware in the CPU but disabled... whether that was physically disabled on the core or just in software I have no idea.

If your CPU has it, it'll be in the BIOS. If it doesn't, it doesn't.

IS yours a Dell by chance?
And ya like everyone said... that is an option that is enabled / disabled only in the bios.

I noticed a huge difference in multitasking abilities between my 3GHz P4 (HT) and my single-core AMD64 3200+. The AMD couldn't touch the Intel as far as multitasking goes, but after I got a dual-core AMD, that changed (duh). Then off to C2D I went and it's SO FKN SEXAH!!! I love that thing.

 

[CompTIA_Rep]

poor AMD.
