Multi core support process

Jon J Reese · Post by **Jon J Reese** » Sat Mar 31, 2007 4:55 pm

Hi,

I have an HT P4. I can't select multi core support in Live, as it is grayed out.

What is the procedure to get Live to recognize the second processor so that I can activate this option?

Sorry if this has been asked before. I did a few searches but didn't come up with anything.

I know other people out there are having/had this problem... I could use the help.

anyone?

P4 HT
windows xp
Live 6.0.5

live doesnt use hyperthreading

when i had p4 with HT i found live performed better if i turned HT off at the BIOS level.

in the event of HT on a P4, it really makes most difference in terms of the OS itself and response time of switching between applications etc.

I'm aware of that issue.However,m I believe that was an issue with builds upto 5 only. Now with 6 and it support of multi core platforms it should support the HT, but it doesn't give me the option

Can anyone else shed a little light on this?

Someone has to know...

Multicore and hyperthreading are 2 different things.

Multicore (multiple processors) are supported.
Hyperthreading isn't supported.

dual core - that is a cpu with two physical cores

hyper threading - that is one cpu with one core but acts to the operating system that it has two cores, multitasking based.

Exactly, I used to have a P4 3.2Ghz with hyperthreading. You are out of luck my friend. The engine in 6 supports multi-core, multi-processor, not hyperthreading.

Sorry.

thanks guys... how is it that a 3.4 just doesn't cut it nowadays? this thing lasted all of a year.

Mac here I come...

It's not that the chip doesn't cut it per se, but that it ran hot, and intel decided to invest its resources in putting two of the cooler running D cores on one chip. As far as clock speed, the core chips probably perform as well or better than the P4s at a lower clock speed, but the real boost is having two of them on one chip!!!

That is why your chip seems so dated, and due to the heat in the P4, I doubt we will ever see a dual P4 in a laptop for the same reason we never saw a G5.

BTW, I went from a P4 3.2GHz to a Macbook c2d 2.0 GHz, the speed bump is intense!

Thaks ofr that explanation.

The new mac laptop is what I'm going to pick up... Though it's hard to deny the desktop's sheer power.
