how to enable Hyper Threading

**NightRise420** · October 28th, 2004, 10:43 PM

yea....i just found out that my cpu supports HT
but its disabled ...how do i enable it?
i know it has to do something with bios but my bios dont have anything with HT
do i have to update my bios or something?

**GroundZero3** · October 28th, 2004, 10:45 PM

how did you find out it supports HT?

is this a factory built machine like dell or something?

What are the specs of the machine

**NightRise420** · October 28th, 2004, 11:58 PM

well when i was testing from 3dmark05
it saids it supports HT
my specs are p4 2.4G currently OC to 2.9G FSB533
512mb (2x256) pc3200 running at ddr333
g4 ti4600 overclocked
thermaltake purepower 420W silent psu
ecs 648fx-a mobo
this is my specs
so how do i enable HT?

There should be a setting in your cmos / Bios setup that will enable/disable hyperthreading for the P4. I thought only the 3.06 Ghz/533 FSB had hyperthreading, Changes ? P4- 2.4C + has hyperthreading/800 FSB.

Any who,, When is Intel going to support Multi threading ( more than two threads)
Oh,,,When they a get a license from the Japanese fisherman,, thats right ,,,lol

and dont forget AMD as well..............

any who Hooray for those E's
Its the core specifications talking, its not configured in the CPU, though.
Lookey here,,, Mobile 2.66GHz HT,, wow wee,,,I missed that group , oops!!

533 fsb processors don't support HT, the overclocking might be fooling 3d mark into thinking it does

EDIT no you edited

**NightRise420** · October 29th, 2004, 11:12 AM

hm...that might be true headband
my fsb is 162 right now
so 162x4 is..... 648 FSB...which is way higher than 533
anyway yea i dont think my cpu supports HT so nvm lol
plus only few programs support HT

I always thought that HT just meant 800MHz FSB

which is supported by any program

no you can disable HT on an 800fsb cpu, and the 3.06 533fsb has it

what it is bisically is a task prioritizer so more important things get done faster

OK, so all programs "support" HT?

**tmgrood** · October 29th, 2004, 09:45 PM

Are you sure the 3d mark program isnt telling you that the "motherboard" supports HT?
Ive got a ECS 848P-A Version 2.0 motherboard and it supports HT but I had to get a P4 2.4 GHz cpu that is HT, for it to actually show 2 processors in device manager.
There's P4, P4 Celeron and of course P4 HT cpu's.

Lots of 533FSB support HT,, check the link I left ,,,,lol

yup, I know, I checked it out, before I saw that, I always use to think that "HT" just meant 800MHz FSB

I think you have to say "Hyperthread Go!" in your best superhero voice when you turn the PC on.

**Fofo** · November 2nd, 2004, 03:13 PM

I have a 3.0 GHz 800FSB P4, hyper threading is ENABLED by default correct?

Regulus

still none of them are 2.4 ghz...and i'm not so sure you should count mobile p4s they suck compared to a regular one

and i believe HT is disabled by default

**Fofo** · November 2nd, 2004, 03:24 PM

So then even though in task manager under performance, it shows 2 cpu's, hyper threading isn't enabled??

**HeadBand** · November 2nd, 2004, 03:34 PM

if it shows 2 it is enabled but i have always had to enable it...you may have without knowing by loading optimal dettings or something of that nature

I recall from the first day of installing I didn't touch the BIOS and it showed 2 cpu's, so I guess it was enabled on my board. Just checkin!

I went from a 2.4 ghz p4 to 3.2p4 w/800 mhz fsb... wasnt really impressed with the difference. My meters on windows default to two cpu's on installation. Does anyone have any lag issues with the HT?

The lag could be because of:
-small amount of RAM/not enough RAM
-slow RAM
-too much crap on your PC

Anyway, yo give you more info post the rest of your specs (esp. RAM)
