I want to upgrade the chip in my PC from 1.7Ghz to a 2.8Ghz i have seen advertised.

My mboard has an fsb of 400 and most chips I have seen are higher than this, the one seen is 800 - is this compatible with my mboard (although wll run slower?)

Is this upgrade worth the bother for medium user?

It would probably run (but not guaranteed) but since it would be going at 1.4HZ on your board, I can't see the point! Odds are your board ONLY supports 100MHz chips (I'm not falling for Intel quad-pump "bus speed" of 400MHz - it's really running at 100MHz, and the "800" CPUs are really at 200MHz). Worse still, if your board is old then it's a socket 423 CPU so the 2.8 won't fit anyway, as it's socket 478.

What model of computer is it? Or if you know what the motherboard is, what is it?

the board is a via p4xb, socket 478

probably shouldnt bother then if the front side slows it down?

Yes, that board is for 100MHz fsb CPUs only. Technically you can overclock up to 199MHz, but I don't think the PCI and AGP buses are locked, unlike with Intel chipsets, so you 'd hit problems.

So sadly you need a new motherboard to take advantage of that newer CPU - that would add about £80-100 to the cost.

oh well, will wait for decent bundle.

thanks for the advice, just as well i asked!
