I'm a bit confused about MMC-1, MMC-2, micro-PGA, micro-FCPGA etc.

I have a Thinkpad T20 (PIII 750) and a Thinkpad 600X (PIII 500).
I know the T20 can support up to 1GHz 100FSB, and I've heard the 600X
can go a fir bit higher than 500MHz (not sure about the cooling system
though).

BUT - could I - for example - up the T20 to 1GHz and hand-me-down the
T20's 750 to the 600X ?

No Martin, different form factors, the 600X requires an MMC2 module and you
can't upgrade the processors in them.

Do you mean you can't upgrade the _CPU_ on a MMC2 module, or do you mean
you can't upgrade a 600X with a later MMC2 module ? <g>.

What sub-flavour of CPU is the T20 ? micro-PGA or micro-FCPGA ?

TIA :-)

The former, you can't swap the CPU on an MMC2 module. You _can_ swap MMC2
modules in the 600X, but I've never had long term good luck with upgrading
the non-speedstep 600Xs. My personal 600X is upgraded to a PIII 850MHz MMC2
and I've got several PIII 800MHz ones also.

Another denizen here in the NG (and a good friend but lousy pilot) is TJ,
AKA Capt. "Wild" Bill Kelso, USAAC. TJ reports that he's had success with
upgrading even the PIII 450MHz 600Xs, so apparently there have been some
successes with the non-speedstep systems.

micro-FCPGA IIRC.

This is what I would have _thought_ ...

From what though ? Presumably something later than a 500 ... Am I right
in thinking that the 500 is pre-speedstep ? My (reasonably educated)
guesswork tells me that putting a speedstep module in a
non-speedstep-aware machine/BIOS/VRM would :-

1) _Work_ ... but ...
2) Possibly result in a BIOS error message at power-on
3) Make the speedstep module run at its lower speed, probably negating
the advantage you're trying to achieve <g>.

Yeah - I think I heard from him fairly recently about this ... he didn't
mention if there was any BIOS code or other hacking involved ...

I think that TJ has forgotten to mention that you have to install the Intel
Speedstep utility IIRC.

Is it possible to stick a Pentium 3 Mobile 1GHz at 133MHz into a T20
and have it run at 100MHz, or do I need to find one that is rated at
100? Is the 1GHz limit inherent to the ThinkPad, or just that there
were no CPUs at 100MHz FSB that went higher than this?

Many thanks in advance! :D

I think you're right, there were no P3's over 1GHz that didn't use a
133MHz FSB. However, P3-based Celerons went all the way up to 1.3 or
1.4GHz using 100MHz FSB. The Celerons at that speed are Tualatin core --
Intel bumped up the P3 to 512k cache, and the Celerons to 256k cache.
So a Celeron at those speeds is still a pretty good performer. They
might be hard to find, though. And it is possible that a Tualatin-
core chip might not work in your laptop. There are some compatability
issues, although those issues might not be present with a Celeron.
I know for a fact that some P3 Tualatins will not work in certain
motherboards, but there are socket adapters available. It's still
the S370 packaging, so I don't know what the deal is. Maybe voltage
requirements are different.

And putting a 133FSB 1GHz CPU into a 100FSB laptop should work, but at
a reduced speed. The multiplier is locked on P3's, so you'd be
looking at 1000 / 133 = 7.5 multiplier, times 100FSB = 750Mhz instead
of the 1GHz you wanted. It'd probably run nice and cool though. :)

Wont boot, cpu must be the same bus speed. The T20 will take a 100mhz bus cpu.
I put a 900mhz cpu out of an A20 in my T20 and it works fine. You MUST watch
the cooling tho. The cooling table is set for 700mhz heat.

Thanks for your replies - that's cleared things up a treat :D 

Yep - I've been reading up on www.thinkpads.com and I'd need to get
the cooling assembly from a higher-end T-series for it to work
properly. I think for my needs it would be better to go for more RAM
and perhaps a quicker hard disk.

Many thanks :)

Those are your better/easier upgrades. The RAM increase is the first, follwed
by faster HD... 5400 to 7200 rpm... then the cpu upgrade

I have a trusty old 600X, which I would like to upgrade to a 850Mhz
MMC-2 Pentium III processor. Unfortunately, these are getting about as
rare as moon rocks. Can someone point to a source? eBay has not listed
any for a long itme now.

TIA,

Jerry

don't bother, it won't work. Even though the physical packaging is
mmc2, the motherboard chipset would not know how to implement the
instructions set from the p3. Not to mention, the cooling issues. Just
sell your 600e and buy a A2X, t2X.

600X, not a 600E, and they work just fine! I've upgraded about a dozen 600Xs
to the PIII 850MHz MMC2.

I've got a few PIII 800MHz MMC2 modules left. Email me if you're interested.

Yes, the 850s are about as rare as hen's teeth, although I recently found a
source and grabbed two against future needs.

Now if I could only find some 2.6GHz P4Ms for my T30 and A31!

The -X -can- take up to an 850, but you dont have to go that far... there are
lots of 650, 700, 750, and 800 cpu's around... just look for the MMC-2 form
factor.. and any of those are faster than the 500mhz. I have two spare 700's on
hand, but can only ship/mail inside US.

"buuuzzzzzzzzzzzzzz, nope, I'm sorry Albert, thats not the answer we're looking

Sorry Al, you dont know what you are talking about. The 600X will take up to an
850MHz CPU. I have swapped out the 500mhz cpus in three -X's and they are
screaming right along at 800mhz. Flash the BIOS with the latest, turn it off,
open up the hood, yank out the 500, stick in the 650 to 850mhz CPU, slam the
hood, turn it on, load up SpeedStep, siddon strapin and hangon.

my bad, i mistakenly thought the upgrade is for the 600E, some of which
also use the mmc2 packaging.

Back a year or 2, the price difference between 600x and the A or T
series was substantial. Now, it is not. By going to A or T series, you
also upgrade the video for the gaming enthusiasts.

Personally, 600e will do fine. the Apps i use do not require a great
deal of speed. To address slow window startup and shutdown issues, i
use the more stable windows 2000 hibernate and resume feature; it does
the trick for me.

Uh, the motherboard chipset does not "implement the instruction set", that's
what processors do.

Aha, so you're the guy ! I should have guessed. Email on the

you are correct of course, p3 implements the instruction set.
OEM engineers also put other controllers (i/o, multimedia etc) into the
chipsets to lighten the load on the Intel processor, these controllers
change as more and more newer i/o technology comes online, like USB1.1,
USB2.0, USB3??, firewire,flashmemory cards etc. A2*/t2* motherboards
would support newer i/o, faster video etc the microPGA 850 processor is
way cheaper than mmc2 850 processor. microPGA packaging goes up to
1000mhz if i am not mistaken.

Nope, they put them there to provide interfaces to external devices.

Some day maybe.

So?

Uh, at 850 MHz talking about "faster video" is kind of like talking about a
"chaster prostitute".

all interfaces have controllers (processor) in them with instructions to
handle the data transfer task. ( ethernet, modem, sound, video,
parallel, serial, usb, firewire)

If you redefine "processor" to include a UART or the like maybe. The only
one of those functions that normally has anything that a computer scientist
would define as a "processor" is video, where the processors on high-end
boards are as complex as CPUs but specialized to the task. There are
ethernet boards with onboard processors that perform various tasks, but
they are not common and are seldom incorporated in typical chipsets used on
motherboards. Serial is handled by a slightly improved version of the same
UART used in the original IBM PC--only real difference is that it's now
implemented as a standard cell in a VLSI chip instead of as a standalone
chip. Modems used to have onboard processors but the trend has been away
from that, with processorless modems (aka "winmodems" or "linmodems") that
use the CPU for the functions formerly performed by the onboard processor
becoming the norm. Parallel is just a different reciever/transmitter chip,
again different in no major fashion from the one in the original IBM PC.
USB and Firewire the same, just bridging from those interfaces to PCI.
Even the disk interface normally has no processor--there _is_ a separate
processor involved, but it's on the disk itself, not the motherboard.

For each of these functions there are boards with onboard processors to
support the function, but they are typically specialized and somewhat
expensive products such as multiport serial boards intended to be used to
connect dozens of terminals, not devices that are normally found on a PC
motherboard.

Sorry, but you seem to have been seriously misinformed about the details of
implementation of the various I/O devices on contemporary motherboards.

With respect, I dare to disagree. Actually right now I am clicking on
Thinkpad 600E (gorgeous machine!) with pII 500 MHz processor installed and
running with no problems at all.

I read many posts on newsgroups that argue that 600E mainboard can't hold
MMC-2 pIII processors because of issues with boot (217 error) and embedded
32 megs of 66MHz RAM. Well, there is a forum (look for address below) where
I found answers to all the qestions. Now my 600E boots without tiniest
errors and runs with 500 MHz without memory instability at all (the key is
to modify, with embedded CMOS editor, few bits that disabling onboard RAM).
One and only problem (or rather a tiny disadvantage) is that L2 cache is not
enabled at boot time and one has to explicitly enable it later. But there is
a tool for Windows to do that; and Linux users have a special kernel module
for enabling L2 cache (both I used).

If someone is interested, here is the source:
http://www.wimsbios.com/phpBB2/viewtopic.php?t=4046&pos...
&start=0


"Sharedoc" rules the forum, he is the first who found a solution for most
600E upgrade problems :-). His solutions I have tested personaly and I
simply can't tell how happy I am that my DVD movies are playing flawless on
600E at last.

And Sharedoc et al planning to hit the 1000 MHz record in 600E :-) (they
developed a mod -- with soldering, unfortunately -- for enabling Speedstep
processors to run at full speed...).

Apologize for my poor English skills, by the way.
