slot 1 Pentium 3 swap

[Guest58]

Hi there CPU-lovers!

I need your help please.

I have an 450mhz Pentium 3 slot 1 in my PC. I bought a second hand 800mhz Pentium 3 slot 1 and fitted it to my motherboard.

Unfortunately all I get when I switch on the PC is 4x loud beep from the motherboard and that is it, nothing happens

I looked at the part numbers (thanks to the great part number indentification section on this site!) I know the voltage is slightly different.
The 450mhz = 2.0v
The 800mhz = 1.65v

Can the difference in voltage be the reason it does not work?
Do I need to get some kind of adapter?

Thanks in advance for your help!

we will need the model number & make of the motherboard

but u may just need to reset the bios back to defaults for it to accept the new processor

Hi Neon, thanks for the reply|!

Mobo is a Intel SE440BX-2

PhoenixBIOS 4.0 release 6.0

Is this what you needed?

just did a quick check of supported processors on the intel site

http://support.intel.com/support/motherboards/desktop/se440bx2/sb/cs-013634.htm

a 600MHz needs bios version of P12
i presume its 512 not 256kB cache 600MHz P3 u have?

here is the main site for the board, while i look at possible reasons

thought this might help also (in FAQ section)

not all revisions of se440bx2 support coppermine CPU, and a BIOS update is often needed;

see the following page on intel's site for full CPU compatibility details, and compare with your board's revision and BIOS version:
