AthlonXP-M for 133MHz FSB m/b?

Hi. This is not quite overclocking, but this is the best place to ask :)

I'm looking to upgrade my Asus A7V133-VM KM133A 133MHz FSB motherboard.
The fastest thing I can see to put in this FSB speed is an Athlon
XP-Mobile Barton 2600+ 133/266MHz FSB 2.13GHz.
Would this be likely to work in my motherboard? Would the low 1.45vcore
be a problem? The m/b does nothing but autodetect for the vcore.

Would this Powernow thing be a problem (I read somewhere they don't want
to run at full speed in desktop m/bs)? I read something about pinmodding
them so they'll run at the correct speed, is this possible? Do the XP-Ms
still come unlocked?

Since they run cool, would my current Thunderbird stock hs/fans be
enough?

Thankyou!

2800+ MP would be the fastest. Barton core with 133MHz FSB.

Parobably.

Good question. Don't know.

Pinmod. Set anything you like.

I have never seen the stock HSF's, but I wouldn't use it on any of the
cpu's. TR2-M1 for $8 works great and is quiet.

From Newegg.com:

Model: AMD Athlon MP 2800+
Core: Barton
Operating Frequency: 2.13GHz
FSB: 266MHz
Cache: L1/64K+64K; L2/512K
Voltage: 1.65V
Process: 0.13Micron
$169

Model: AMD Mobile Athlon XP
Core: Barton
Operating Frequency: 2.13GHz
FSB: 266MHz
Cache: L1/64K+64K; L2/ 512KB
Voltage: 1.45V
Process: 0.13Micron
$104.00

Unless there's some L3 cache I don't know about, I think they may be the same
processor.

But there seems to be an XP-M 3000+ 2.20GHz(133x16.5). I wonder if those could
go to 3GHz ;-)

Great.

I'm basically wondering whether it's possible to force the XP-M to use its
correct multiplier (eg: 16x) rather than automatically revert to 133x6 because
of the unsupported ''Powernow" feature.

Ok, the XP-M dissipates less than my current CPU, so I think it'll be good
enough. I was just wondering how well it'd physically fit, as I've read
Thunderbird heatsinks aren't right for Bartons for some reason.

This reminded me..
Got any idea as to why there are no 166 - 200 fsb MP boards (or processors)
out there?

Has to do with the low vcore....lower fsb produces less heat...does this
make sense?

AMD never made a SMP chipset that supported anything above 133MHz
(officially) afaik.

basically, they are.

Well, you could get a little more speed out of this one.

I have no experience with the mobiles but I've heard that they start out
at the highest setting and that this setting can be changed via the L12?
bridges on the cpu. Don't tke L12 for granted, it may me another group of
bridges.

But the surface area of the new cores is smaller than the tbird cores. I
used my pretty good all aluminum cooler for a while, but in the end the
cheap new copper base cooler worked a lot better with the tbred core.

Higher FSB speeds needs better RAM, northbrige chip and cooling and
generally needs better motherboard components. These are more expensive and
needs more power and outputs more heat. Extra heat in a notebook is not
good and power requirements needs to be kept as low as possible for decent
battery life.

You look at a 1.0Ghz Intel Centrino processor and is uses a 0.9v Vcore! Wow!
Overall, Intel are better (at the moment) at making chip for mobile devices,
in my opinion.

Kinda
but
200 * 10.6
166.66 * 12.8
133.33 * 16
They should all produce similar heat shouldnt they?
and shouldnt they all run at the same vcore?

Got that proc from newegg and put it in a MSI K7T Turbo 2...KT133A chipset
15X141= 2115mhz- mem at cas2.
15X147= 2205mhz- mem at cas3.

Needed a program called CPU MSR to reach the 15X multi,
wouldn't go higher than 13X without it.
