Socket 370, and FC-PGA...

[Comage]

Hi guys, I currently have a Pentium III 600E (100Mhz) CPU running in my Asus CUBX (Intel 440BX chipset), and I have thought that I'd pay for a cheap upgrade to the highest end of the Pentium III line.

I was looking at the Intel Spec Finder link found here:
http://processorfinder.intel.com/list.aspx?ProcFam=25

and I see that my processor is labelled as a "FC-PGA" package type.

The fastest process in that list is the SL5QW, and it is labelled as "370" package type.

Would this processor work in my CUBX?

I know that both of these processors have 370 pins, but I'm unsure as to why Intel terminated the Pentium III 100MHz line (1.1GHz) with a 370 processor instead of a FC-PGA processor.

I had thought FC-PGA was a newer standard?

socket 370 and FC-PGA are describing 2 different things. Flipchip PGA is the CPU packaging.

unless you have a slocket card, you'd need to get a Slot1 chip.

Thanks for the article, Midknyte.

My board is a socket 370 board, and I am currently using a FC-PGA processor in it, so I'm not using a slot key.

I guess I may just have to take a plunge in here and hope that the processor works on my board.

It's a little odd that at this site, entering "SL5QW" into the S-Spec database, shows a FC-PGA processor.

I guess Intel labelled it wrongly or something?

ah. i saw the 440bx on there. that's an unusual setup.

Coppermine "E" CPUs should work ok. look at the asus site for cpu compatibility.

You won't get much of a performance boost unless you replace the mobo, processor, and RAM.

Socket-370 was altered three times. First came the Celeron-only PPGA370, then we got PIII-enabled FCPGA, then FCPGA w/ added 133 MHz support, and then finally FCPGA2 with altered electrical parameters for "Tualatin" processors.

With an Intel BX chipset, you probably have the 2nd flavor - 100 MHz bus, Coppermine PIII/Celeron (green lidless FCPGA) or Mendocino Celeron (black PPGA). 133 MHz Coppermine or Tualatin won't work.

Thanks for all the replies guys!

BPB: Thanks for the link, but unfortunately, legacy stuff is hard to find here; even more so for PowerLeap stuff.

I know this is a dead bird, but unfortunately an overhaul to a new P4/Sempron/C2D is out of the question at the moment. :t
