This may be a duh! duallie question...

[GeoffS]

Do the CPUs have to be of the same speed? I have a bunch of Celeron chips, but no matched ones (yet!)... could a 366 and a 400 run together?

Thanks!

They sure do GeoffS.
You could do it by over/underclocking one of the CPUs to match the other as they are close together in speed.
I'm also 99% certain they'd both have to be Celerons or both be P2s etc but as you've got Celerons that's no problem. Likewise, you'd have to make sure they were the same kind of Celeron.

I'm almost sure I read someone posting here about his running dualerons with mixed speeds. Think it was theMagiman, not sure.

 

[GeoffS]

They are all original celerons... I'll have to give it a try! 🙂

Original celerons (slot 1 kind) won't do SMP without being hard modded.

The celery a version (socket 370) will only because they have done the pin mod on the slotket, or motherboard as in the BP6.
I've never run dual celery without adjustable slotkets, or they have all been on a BP6.

Kilowatt- I am using dual capable (and properly jumpered!) slockets. I'm currently using a Gigabyte 6BXD with a pair of slocketed c366@550... that puppy has been running Klinux for 66 days straight! 🙂 Tonight, I am setting up an MSI 6120N with a pair of c400 (found another one in my stash!) ... dunno how well they will OC, so I'll start at 400 and go from there! 🙂

 

[Kilowatt]

Cool Bud, you said "original" and since both 366 & 400's were made in the slot1 interface, that's what I thought you had.
/me is felling better about it now 😀

 

[GeoffS]

heh... OOPS.... 😱

Possessed Freak has successfully run a P2 400 and a P2 (unlocked) at another multiplier, and therefore, different frequency. I don't understand exactly how it works, but you're supposed to use CPU's of the same clock speed.

[EDIT]Had to change it to 400, 'cause I'm stupid and haven't slept in 2 days 😱

 

[Sukhoi]

Remember the celerons have locked multipliers so you'd need to alter the FSB of one of them to get 2 different celerons running at the same speed, and I don't think you can run 2 different FSB's. 🙂

 

[Possessed Freak]

BK is right,

I ran an unlocked 400 and a locked 400 together. I changed the multiplier on the motherboard to 4.5 and the unlocked ran at 450 and the locked at 400 just fine.

I do believe the multipliers are overridden by the CPU's so it *might* work. Best idea I have is: 1) put in the faster cpu alone, set the multiplier on the mobo (bios) to the faster cpu 2) put the slower cpu in the second slot...

see what happens...

Cool! 🙂
