I've been hearing rumors about it for years. Intel has finally
released an overdrive chip for the PPro. Looks great on paper.

So, have any of you fellow PPro owners upgraded?

I love my 2 1/2 year old PPro, but it's showing it's age, and
is a little slow, 15fps, on GPL. Will the Intel overdrive give it
a little more life, or should I just live with it and wait for
Katmai/Tanner in six months?

Thanks

Larry,

Honestly, as a former dual PPro user (til my SuperMicro motherboard tried to
fry itself), I'd seriously look at building a Celeron 300a or 333a machine.
You should be able to get the basic box (case, mboard, 128mb ram, processor)
for the $600 that Intel wants for the PPro Overdrive chip - and if you can
overclock the Celeron, even better.

If you could somehow get the Overdrive for $300, it might be worth it, but
you'd get so much more by going to a PII/Celeron - DIMM slots, AGP graphics
capability (still not being used in my PII-300), UDMA IDE controllers, just
a more modern machine all-around.

The amazing benefit of a p2 overdrive is it is basically a xeon. The ppro
was and is an excellent chip because its cache runs at the processor speed,
not bus speed as in socket 7 chips or 1/2 processor speed as in pentium 2
chips. So, for whatever the chip costs (I have no idea, probably too much,
intel overdrives have always been outrageously expensive) you get a Xeon 333
I believe it is which is probably overclockable at least a smidgeon. What
does this mean? Well, since you posted to sim groups, I assume you are
interested in games performance. I don't have any numbers but I believe
sequential operations, as in a business app more than a game where code is
totally dependent on user input, benefit most from speedy and large L2
cache. Basically, if for some reason you would have to buy all new
everything to go with a true P2, it's probably just not worth it financially
to get the overdrive. If however you need superior business app performance
(and I'm not sure if a dual ppro can be upgraded to dual overdrives, which
would of course yield the greatest gain) or can get your hands on an
overdrive cheaply, it may be something worth considering. Also, remember
that the intel overdrives are marked as, for example, 120/133, which means
if you are too stupid to change a jumper, you get less performance, even
though you paid for more. Note that this is not overclocking, and I'm kind
of shocked intel wouldn't explain that the overdrive doesn't give a shit
what chip you used to have, but will (to make it easier I suppose) take the
current bus speed and run with it. In other words, if you have a ppro 150,
tell your computer its a 200 (or at least change the bus speed to 66 or
whatever your board supports) before you go with an overdrive...

My PPro/200 is a totally competent Solaris S/W development
workstation and a WIN98 sim-station with 1/4 Gig of parity EDO,
Adaptec 3940UW (duel Ultra SCSI), 20 Gigs on 3 fast IBM ultra
drives. Fast DATs and CD-ROM, on the second SCSI bus.

In anticipation of my next computer, it has recently acquired
a Obsidian2 X-24 and a Montego.

The only number I can give you is 15 fps in GPL at
Nurburgring, with the default five competitors, 1024 by
whatever. The Montego set to Digital joystick.

It's a smooth 15fps, and I would have guessed higher. But
that's probably right, and kind of disappointing.

It's not like I'm dropping a Ferrari engine into a rusty
Rambler. But, ya' know, $600.00 bucks. If already does a fine
job for development. A 333 processor with, as Patrick said, the
faster cache currently available on a P2.

Anyway, that's my story.

Thanks
Larry

I have a PPro 200MHz CPU and would like to get a little more out of it. I think
the motherboard is an ABit one but I have no idea what the bus speed is - I
would guess 66MHz. Are all PPros Socket 7? Can I put an AMD K6-3 and K7 into
this board when they become available? I use the machine for *** only and
would rather upgrade it than replace everything. Is the Overdrive the last ditch
for this box?

PPros are socket 8 not 7.

No, PPro's are socket 8, and they are (to my knowledge) the _ONLY_ chips
designed for socket 8. If you don't want a new motherboard, your only
solution is a P2 overdrive. I also don't believe any PPro boards (at least
officially) support higher than a 66MHz bus. It's possible that a more
recent high quality PPro board might have jumper settings for it though. If
it does, you can squeeze significant performance out of an overdrive. (I
would assume they are multiplier limited, if not locked, so you could get
5x75 = 375MHz or if you are really lucky, 5x83 = 415MHz) Otherwise, despite
the obvious benefits of a fast L2 cache, it probably wouldn't be worth the
money at this point. Now, if the overdrives were like 300 dollars, rather
than the 600 I suspect, it may be better than a new motherboard/ram/P2, even
if you got a celeron and overclocked it (which of course holds no
guarantees)

I have overclocked my 2 year PPro 200 to 233 and it work fine without any
major problem. I think it is a little faster than it used to be :)

The OD PII pumps a Pro 200 up to 333 and the bench marks suggest a
SIGNIFIGANT improvement in performance in all area's..intel has the Specs
and some third party tests on their site. Unfortunately, the price is also
SIGNIFIGANT (over 500 bucks) so its in that "Muddy" area where in the long
run it might be worth dropping the other 300-400 to get a real PII, a new
Mobo and new memory etc

This was something that was pondered by many, but was found that the BX and
LX boards would not recognize the PPro OD. There was hope that the ALi (?)
PII chipset would recognie the chip, allowing 100MHz FSB with the riser
card, but I am not sure of the outcome yet.

Anyway, from the benchmark results I have seen on Intel's forum that have
been posted by people who have bought the chip show that it is very fast.
