Question about cpu

[budsmoker997]

ok i know i only got one cpu in my comp but in like device manager it says i got 2 and several other things say i have 2 and before it use to say 1 i dont know how it happend and i dont know if it will hurt anything but does anyone know how to fix it?

If you are running a P4 with HT then it will emulate itself as two CPU's. If you are running either a PD, Core Duo, Core 2 Duo, or Athlon 64 x2 which are dual core CPU's then in fact you do have 2 CPUs in your computer but they are located on 1 chip.

"Dual core, do more..."

You should've told us what CPU it was.

Central Processing Unit.


In respect to anyone who didnt know.. of course



and ten seconds later I realize what you meant by that post.. and I sort of doubt that someone not knowing what hyper threading on a P4 shows up as.. would know what type of CPU they are running under the hood, so to speak.

Having never encountered HyperThreading (but heard of it) I wouldn't know either But I tend to know most the ins and outs of pcs

 

[Sardaukar]

Normally hyperthreading is handled differently on other processors, the old pentium 4 series just had an odd way of handling it.. it did help on server platforms to a mild degree, but it really never had to be that way.. just an old chip

i dont know but thanks......not to worried about but was curious

my cpu's are
intel(R) Pentium(R) 4 cpu 2.80ghz
intel(R) Pentium(R) 4 cpu 2.80ghz thats all i know about it thats all it says

dont know much about hardware :S

i just bought my comp as it is and put it in another case and addes some ram and another hdd other then that its factory

Your processor just has HT. All but one type (only limited numbers also) of 2.8ghz Pentium 4 is HT.

HT is what Sardaukar said. It's Hyper Threading. Which that simply means the CPU can handle more then one thread (in the case of the P4 it's 2) with no performance loss.

So the OS sees the CPU as 2. With each thread representing as a different CPU in the OS. So the OS can assign different programs to run on different threads.

So having it there doesn't hurt your computer at all. Performance of it depends on what you are doing anyways. If you run serveral CPU intensive programs at once like you do on a server or workstation then you'll see performance improvements. So if you like play games while encoding audio/video then it will benefit you. Otherwise if you just do a single thing at once it's best to turn it off as you'll see a slight performance boost in single tasks.

thx alot nopeace

how to turn it off?

 

[Rishwin]

thx alot nopeace

how to turn it off?

i dont think you can turn it off lol... but why would you want to?

It's in your system BIOS. There's an option there to disable HT.

Better single threaded performace.

HT lowers the CPU performace in order to do more at once.

kk thx man

before my upgrade (when i had a p4 HT)
Photoshop wouldnt run with ht enabled...

Nopeace are you saying that if you disable HT,
You would have more fps/preformance with games ? :O

Yeah some. Only on single threaded games. So for games that use the HL Source engine then forget about it as that's multithreaded.

I believe that the source engine is NOT multi-threaded to date but will be once Episode 2 is released

It is. One thread for Physics and one for AI + Environment variables.
