HT CPU in NON HT mobo, and vice versa

[zixxer]

Okay..

Will a hyper threading cpu work in a non HT mobo? How about vice versa?

Thanks..

 

[stardust]

i started a thread about this already and was attacked by all sides..

but anyways...there are adapters u can buy to allow HT support for motherboards but no vice versa

The mobo MUST support hyperthreading in its BIOS, not sure what kind of ADAPTOR can do this. You can mix and match mobo and cpu without problems but you will not get hyperthreading. The mobo BIOS has to initialize the second logical CPU and pass the info to the OS. HT can be disabled in the BIOS.

Hyperthreading ADAPTOR thnk u

What the freaky!? It's like a slocket!

EDIT:

PowerLeap now offers an adapter which can help to make many mainboards HT-capable. The prerequisite for it, however, is BIOS support from the manufacturer. In practice, there are a number of boards with chipsets from Intel's 845 line that are supposed to be "upgradeable" in this way.

if you actually read that, it notes that not all boards will work with it
you have to make sure the chipset, and hte chipset rev, both support it (even if its not "official")
i didnt read much, so maybe theres more...


otherwise:
HT cpu + non HT mobo = check
HT mobo + non HT cpu = check

check= will work

however, HT obviously will not work

First off, Powerleap makes great products... but this one is pretty wacky. Many planets have to align just right for this baby to work.

As for the original question: Yes, a HT cpu will work in a non-HT board. You just won't be able to take advantage of HyperThreading. And yes, a non-HT cpu will work in a board that supports Hypterthreading. But again, you won't magically be able to us HyperThreading.

what he said and what mobo are you currently using? most i845PE mobos support HT through a BIOS update

most MB that support a 533 fsb supports HT. forgot the source, but its reliable

LoL! I remember those

Okay,

So the PC's will work, just no HT? Cool. Thanks

You mentioned HT, but what you should be concerned about is whether or not the board can support the 800mhz FSB. Definitely not all boards can support a 'c' chip (w/800mhz FSB).

 

[stardust]

yep, u gota see if ur bios can go to +200fsb, then u have a slight chance
my old SOYO P4X400 Dragon P can take "C" cpus cuz its new bios allows 300fsb..
tried and true

I have an MSI 845-Ultra ARU.. I don't know if it supports 800mhz fsb or not... any ideas? I looked on msi's site and couldn't find any info..

And the cpu in question here is a 2.8ghz HT cpu I can get for cheap cheap cheap. I have a 2.2 right now..
