Is it possible to buy a P4, 478 with 100 Mhz FSB?

[Ian R]

Hi

My friend has a PC with a Shuttle AV41 systemboard and he'd like to upgrade
the CPU (currently 1.7MHz)

The spec* says the fastest processor it supports is 133MHz FSB Pentium 4
socket 478 3.06 GHz. Is it still possible to get these?

Most socket 478 P4's Ive seem for sale are 400+FSB

*See

Thanks for any info

No, Intel no longer makes that CPU. It was discontinued a year ago. I know
because I bought one of the last ones for my Asus P4PE motherboard.

Howdy!

There's still some stock out there, although either OEM or
used/pulls.

Yes, it is. But it says 533Mhz on the package.

The RAW clock is at 133MHz. But Intel uses a quad-pumped clock, so
they call it 533MHz instead.

Confusing? Yes. But it's no different than the "200 / 233 / 333 /
400"MHz AMD processors - save that AMD uses DDR clocking.

That is showing the FSB clock rate. Marketing of course prefers to use the
FSB data rate which is clock rate times 4, and see the remark at the bottom
of the table.

I wouldn't expect the board to support Hyperthreading, which is a feature
of the 3.06 GHz P4 CPUs I see for sale. A 2.8GHz Northwood P4 with 533FSB
ought to be a safe upgrade.
