I see this Mobile PIII 733 cpu with motherboard last week from one repair computer shop.

http://cgi.ebay.com/Rare-Intel-PIII-Mobile-733Mhz-No-spec-code_W0QQitemZ260115655278QQihZ016QQcategoryZ3674QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

The shop owner tested the cpu by power on the motherboard and cpu. The screeen show it's 733Mhz so I believe it's not fake cpu.

However another guy(he probably a IT guy) watching the testing said it's fake cpu made by China. The shop owner said it's 100% work. He also said that all of similar sourced from China.

Is it true?

That looks like one of those unlicensed socket conversions the chinese were real good at making.

That IHS looks kinda shotty- Looks veyr poorly made. Also, the traces on the underside of the die look very different.

Mobile BGA PIII on PGA-370 adapter. Probably not correct speed. I think it is 550 MHz (5.5x100) and not 733 MHz (5.5x133). But it surely can work at 733 MHz.

From the specification of Mobile PIII mPGA2 typical voltage is 1.6V. I don't think so overclocked version from 550 to 733 could work with stability at 1.475V. But good idea Mixeur.

its also not a PIII, its a celeron, note the 128k of cache.
and celerons are typically more overclockable.

and found one important detail. PIII with 128 cache ? Impossible. So Celeron with 133 FSB impossible too Smile

I think there was low-power version of mobile Celeron with 1.35 V core. It's not in S-spec database. It should have part number KP80526LY550128.

chinese manufacturers modification. Not available in Plug and Play version Smile

sorry I forgot that Celerons mobile at low speed where with FSB 100. So that is very hard but possible to overclock FSB from 100-133 MHz.

Let me make the conclusion that it's fake cpu.

It's celeron cpu and "make" it to PIII cpu with the adapter, right?

I do want to open the silver cover and find the answer. (If no one buy it, I'll try to open it.)

Thanks all for your view,

Billy
