Can I run dual Celerons (different speed) on the BP6 ??

Batch codes, RAM specs, BIOS settings, etc..

Yes, it should work.

Search the message board for more information, my response was based on experience.

I've had a 466 and a 533 running on my Bp6.

The two will of course have to run at the same speed, typically the lower of the two (don't think that was made clear here)

It's impossible for them to run at the same speed because their multipliers are locked.

The FAQ at 2cpu.com claims that Intel says you can clock the CPUs to the same speed, to the speed of the slower one.
What about stepping and cache sizes?

There is a myth that in order to run multiple CPU's, they need to be the same stepping and cache size. This is not true. According to Intel, you must have the same family of processor, and that's it. In fact, according to Intel, you can even mix MHz! They say that if you clock the processors to the clock speed of the slower CPU, you'll be fine. Mixing cache sizes is also OK by Intel, as long as you're not mixing 1MB or higher cache chips. You're best off if you have the same speed and cache processors, but if you have to try an SMP system you can use whatever is available.
By the way, do not trust the speed readings WCPUID gives, they seem to be wrong. Check by changing the FSB with BP6FSB and then look of at the readings of WCPUID. WCPUID still seems to read the BIOS setting. No "real time clock checking" at all...

Maybe as the system boots up, the processor reads the system state (BIOS) and stores the this information in the its registers. When you use BP6FSB, it changes the FSB of the mainboard directly and WCPUID sees the original system state that was stored in the processor registers.

WinCPUID is accurate. If you want real-time readings use the Real-time Readings module included with WinCPUID ;) :P :D

Hi Derek,

it is not :P :) Despite the nice oh-so-realtime-flickering the "real-time clock checker" in WCPUID produces it still gives me 523 MHz after downclocking while BP6FSB says 366. And the RC5-72 client also says he´s crunching slower, so I tend to believe in BP6FSB (has that nice "BP6" in it´s name, hasn´t it...;))

Best regards,

WCPUID is accurate, whatever you tell, just use the newset version - I guess it was v3.1, right?

the older versions could not get the accurate realtime clock readings.

if not, so use CPU-Z

where wcpuid is still not accurate is on the new boards with canterwood chipsets, where you can use SetFSB - there not even sandra or CPU-Z read the changes in frequency.

besides, if you ever doubt about some readings of any program like that, then use real world!

USE winrar or alike and check the time of compression the same files in the same conditions, before and after the change. if the change is very small, be sure to use big files to get longer compress time and get the difference.

like this I have fidured out that on ASUS P4G8X board in BIOS you are not able to change memory timings above 140FSB - whatever you put it gets you to 2.5/3/3/7 after POST :)
Fortunately there exists tweaked bios for that :)

GOOD luck!
