Thanks for that information, Clint. I'm used to working with AMD processors
and aftermarket boards. I figured most of the same rules would apply to
Intel, but didn't know if they might be more specific or critical about that
stuff. The 850 with the 133 FSB was a misprint.
I know this has the 440BX Chipset, (FW82443BX North, FW82371EB South)
but can't find the actual model number of the board. Does Intel stamp them
in a certain place? The MBs I've been around have an ink stamp that tells
the model number. Maybe its on the solder side of the board? I would have to
completely remove it to see the solder side because of the case design.What
I've found on the Intel site is that there are 2 prefix letters, **440BX
that determines the model number. At least I think that's correct. Maybe
Dell has covered it up with one of their stickers.
Is there anyway to get the heatsink off of the processor without
breaking everything? I tried alittle but didn't want to get carried away.
This has 4 plastic pins that stick through and they look like their
"swedged" or something into the plastic cover side. The reason I would maybe
like to get it off is because of the mounting and the way it locks into
place. Some of the other processors look different in the way they lock into
the board. I figured I would just switch the heatsink so it would fit my
hold-down.
Thanks again for the help.

Subject: Re: PCWorks: Fw: Intel Processor Question
The CPU may work, it depends on the mobo model #, but it's only
going to operate at the fastest CPU speed/bus speed that the
mobo supports. If your mobo only supports 100mhz bus tops, and
let's say for example its max multiplier is 6, this means the
fastest CPU speed will be 600mhz.
Most 440BX boards can support PIII's, but some only with 100mhz
bus while others can support 100 and 133mhz bus. You may want
to look into a slocket adapter and see if your mobo supports
them. These can allow you to use an even faster socket 370
(aka PPGA) PIII on a slot 1 board. Unfortunately, it sometimes
can be trial and error since most mobo manufacturers don't
mention this.
If you'd be happy with an 850mhz CPU, and if Dell says the mobo
will support an 850mhz CPU @100mhz bus, then I'd get the 100mhz
bus CPU to avoid any compatibility problems. BTW, I don't
think there's such a thing anyway as a PIII 850 with 133mhz
bus. That would mean a multiplier of about 6.4 which is
impossible. The PIII's with 133mhz bus are those who's speeds
end in multiples of 33 (633, 733, 766, 833, 866, etc.). Any
one listed as 850mhz w/133mhz bus is either a misprint, or
actually 800mhz.

Hello,
Does anyone know if Intel Pent. III , Slot 1, Processors are
backward
compatible as far as bus speed. Can I put a Processor with a
133 mhz bus on a
board with 100 mhz bus? Will the faster processor just run at
the slower
speed?
The Board has the 440BX chipset. This is a Dell PC with a 450
Mhz CPU and I
want to put in an 850. Some of the 850s I'm finding are 133 bus
speed. On the
Dell website, it lists up to a 850 cpu but with a 100 mhz bus.
I'm guessing
that's all that will work but thought I would ask.
Thanks,
Roger C.
