I'm looking at upgrading my XP2100 cpu running on a Ledtek K7N board
(Nforce2 chipset). Its just a cpu upgrade as I'll be keeping the same
motherboard. I'm looking at a AMD Barton 3000 which runs at 2.1 GHz and has
double the cache as my XP2100. I'm running a ATI 9700pro video card.

Here is my question:

Which front side bus would be better 333 or 400 if the CPU runs at the same
overall speed? My first thought would be the 400. Currently with my XP2100
which is a 266fsb with some oddball 366 ram. When I got the faster ram it
really made a noticeable jump in performance over the 266 ram I had before.
So that got me to thinking that if I run a 333fsb cpu with some 400 ram I
"should" get me better performance than running a 400 cpu and 400 ram. I
know there isn't as much difference between 333/400 (120%) as there is in
266/366 (137%), but it can't hurt. About the only thing I can think of is
that the 333fsb cpu might run hotter since it has a higher multiplier than a
400 fsb version would. Or better yet is there a ddr ram that faster than
400? Then I could go with a 400 fsb and still bump up the ram speed.

TIA

Go for the 400 mhz cpu

Care to explain why?

400 FSB...FSB is very important to the speed of everything.

Speed of what? Both CPUs are runing at the same oveall speed, agp, and
pci bus are running at their standard speeds so what is gaining speed from
the fsb?

I'm not saying your wrong, just trying to figure it out.

Over simplified here Dawg... MHZ means millions of cycles per second,
equate that to RPMs If your car, with 14 inch tires, travels 60 MPH in 5th
gear at 3300 RPM thnk about how fast that same car/tires will obvioulsy go
at 4000 rpms? so this means that so many inches/feet/or miles per second
are going to travel under each "tire" per second (miles per second). Same
idea is about instructions that a chip can process, if it can be fed 400 MHZ
rate, into the 2100 processor, all things being equal the 400/2100 should
run much faster than the 2100/333. the only other change that you could
make to make car go faster would change the tire diameter to larger 15 inch
tires,{think of that as the 64/128/256 buss width changes}

if it weren't much of a gain, there wouldnt be much reason to follow that
path...

FSB = Front Side Bus
Speed of the bus between CPU, chipset and memory I guess.
Memory speed is important.

I run a XP3000 333FSB on a Abit NF7 with corsair Low Latency dual channel
DDR400 and a ATI 9700 pro. The abit board are really good for o/c so i
raised the FSB to 400 and drop the clock to still run at 2.1 gig, and the
improvement is surprising. I've been running with this 333fsb cpu since over
a year at 400fsb without any problems. Make sure you mobo can tweak the fsb
and clock if you plan on doing that.

...The Front Side Bus....

The Front Side Bus is going faster, which means that the memory and
processor are going to be receiving and sending info out a lot faster. For
an easy comparision, look at a P4 2.4 w/400FSB, P4 2.4 w/533FSB and P4 2.4
w/800FSB...the 800FSB is much faster.

Nothing like having someone with direct experaince!
