Abit IC7 and a 400 fsb P4?

[MrMiyagi]

I know on newegg's site they make it clear that "400FSB Not Supported". But under some reviews (newegg's) people have said that they've run a 1.6a and a 2.0a in the board. Anyone else have experience succesfully or unsuccsesfully running a 400 FSB P4 on one of these? I wanna buy the board, but can't afford a new proc. right quick so I was gonna stick my 1.8a P4 in it.

Thanks

No, it won't work.

Read Intel's white papers on i865P/875.

i think all northwoods work. the old willamette's wont work on these..

 

[MrMiyagi]

Yeah, mine is a Northwood...so can anyone else confirm or deny this??

as long as its a nothwood it will work since the mobo can do 100mhz.

hmm... my mistake.

I thought Springdale/Canterwood where exclusively made to support 533 and 800Mhz FSB, as Intel's strategy to discontinue and discourage the adquisition of the old 400Mhz FSB P4's.

So if I plug in a 1.6A into a P875 chipset mobo, initially will it come up @ 1.6 Ghz ( 100Mhz FSB ) or 2.13 Ghz ( 133 Mhz FSB )?

On my IS7 it comes up as 1.6,100mhz, default, and there are memory ratios similar to any other motherboard. I assume that an IC7 would do the same thing, but the IS7 I'm 100% sure about.

400fsb cpus will work.

even my 533fsb cpu defaulted to 100fsb on its 1st boot.

why else would the board have fsb options from 100-133 and a nbs400 if they didnt work?

 

[HigherGround]

thanks guys, now to choose a brand

 

[MrMiyagi]

I'd like to thank you all as well

 

[THUGSROOK]

just fyi....

100fsb has a +3:4 mem ratio option for 266+ddr
if you overclock to 133+fsb youll also have a +4:5 mem ratio option for 333+ddr.

It worked just fine for me when I used my 1.7 celeron... the reason why they "arent supported" has something do to with the williamette requiring a voltage outside of the parameters of what the IC7 supports, or so I've read somwhere.

If you own and IC7, there is no reason why you should be using a 400fsb proc for more than a month or two anyway before upgrading to an overclocking 533 or a cruisin 800
