What does FCPGA means?

[Enkrates]

Hi, I am looking at a socket 370 pentium III chip and I see FCPGA. What is it? What does it means? Do all socket370 have FCPGA ? Do slot 1 has FCPGA ?

FCPGA = Flip Chip Pin Grid Array

It is a type of packaging for the chip itself. On a FCPGA chip, there are actual pins on the back of the chip that fit into a socket on your motherboard.

A slot1 CPU literally fits into a slot on the motherboard.

They are completely different. If you have a motherboard for slot1 CPU's and you have a FCPGA CPU, you can buy a FCPGA to Slot1 converter called a slocket. Try searching the forums for some more information on where to buy one (if you need it).

Oh if there is anything you are unclear on, be sure to ask. Thats what we're here for.

FCPGA = Flip Chip Pin Grid Array

Only Socket 370 has the FCPGA (for Intel chips). No slot 1 chips are FCPGA, but not all Socket 370 chips are FCPGA. The original Celerons were PPGA and socket 370 (plastin pin grid array), but all P3 socketed chips are FCPGA.

FCPGA is specifically for Pentium IIIE (Coppermine) and Celeron II CPU's. Essentially, it's the socketed form as stated above. PPGA was for Celeron CPU's with on-board cache. The chipsets are actually different though they look physically identical. It's important not to confuse the two, because they are not electrically compatible, although there are converters from both PPGA and FCPGA to Slot 1.

One more importen thing you other guys forgot to tell. The fcpga chip is actually upside down so that heat can get off the core much faster. This is not the case with the old Socket 370, but they both use the axact same amount of pins which means that if the mobo can handle both then you actually can save some money .

PPGA was used for all Celerons.

Err uhm. Slot 1 was used for Celerons up to about the 300A. Dunno if they made PPGA cache-less Celery's or not. I do know that the 300A was made in slotted variety cause I have one laying around somewhere . Anyway, I'm not 100% positive about whether or not any cache-less celery's were made in PPGA format, but the switch happened around the same time.

Up to the 366. Not many Slot-1 366's though.

Hmm, what about AMD chips? The Duron spec sheets seem to refer to it as PPGA. Might be mistaken though.

 

[AndyHui]

Slot 1 Celerons existed up to 400MHz as both retail and OEM, 433s were OEM slot 1 only.

PPGA applies to Celerons from 300A to 533.

There are no PPGA Celeron 266 and 300.

Durons are Socket A....they have nothing to do with PPGA.

Durons/TBIRDS are also flipped, hot side up. ALL Coppermines regardless of Socket or SLOT use flipped Chips, but FCPGA specifically refers to Socket 370.
