600E - 2645-8BU - CPU upgrade questions

[Lacyt]

TP 600E - 2645-8BU, PII 400MHz

Flashed to current BIOS so it now supports 512MB PC100 and Windows XP.

Will this one support a PIII 850? SpeedStep or Non-SpeedStep?

Does SS work the same in Thinkpads as it does in Dell laptops; i.e., if the laptop is running off the battery, it automatically adjusts the CPU speed downwards to conserve the battery.

Yes, it should handle either the 850MHz SS, or non-speed step version....

I would just be careful of heat that an 850MHz will create.

Thanks!

Just now found this download, if anybody's interested.

Adds support for the SS CPU issue with the 82440BX chipset, soft audio/soft modem, PC Card, and USB Audio noise, adds ICC Color Profile, and resolves some issues a long list of these older laptops have running Windows XP.

I think that the XP Supplemental files for the 600 series only address two items:
1. cstateflags registry patch
2. LCD colour profile

The rest of the patches and files in the XP Supplemental Files disk are for other Thinkpads, not the 600 series. Make sure you check the installation instructions for each one before trying to apply it to your machine.

I'm not quite sure what the cstateflags patch does, but the SpeedStep support that is referred to in the Supplemental Files disk, refers to an 82440MX motherboard, not a 440BX:
"- (New) Support INTEL SpeedStep Processor Issue with 82440MX"

Nor are some of the other patches you mention relevant for the 600 series: soft audio/soft modem, PC Card, and USB Audio noise.

If you upgrade your CPU to a PIII SpeedStep CPU, then you are most likely going to run into the same problem that most 600E upgraders have: the CPU will initially run only at the lower SpeedStepped speed (150MHz below the maximum speed). Read through the Official 600 Series Upgrade thread for some ideas about how to get around this limitation.

Also, even if you do apply the required mods/software to get your new CPU to run at max speed, it wil never function the way SpeedStep is "normally" supposed to function, since your motherboard most likely does not have the necessary SpeedStep hardware to produce this functionality properly. You will most likely end up either always running at the low speed or always running at the high speed, regardless of battery/AC connections.

600e+600x don't need any of them supplement files to run xp properly.its more like xp pro was made for them,
xp loads every single driver .integation is seamless and of the highest standards bar none!
i remmember a few years back all drivers loaded perfectly even on
the ol 600 too.
the 600x is comfirmed to be 100% vista compatable +fully supported too.you can load vista on 384mb ram from dvd clean install + or duall boot with xp (contary to myths about minimum speed + ram it cuts through vista no sweat with sidebar gadgets glass effects on only 320mb ram a 500mghz?!!! runs like xp pro on 128mb+ win2k on 96mb.
win 2k+xp drivers are fully compatable,i disable aero ram hogging,manipulating evil, and use 2k glass software enabled programme as a superior means or rendering glass effects+ 3d flip with other proggie as the way to go with vista,
amazing what the 600x gets away with.
bring on the 600e with vista too


*with the modded spedstep cpu +deepsleep utility on the 600e,once done correctly (with cpu msr cache enabler)it
works even better than the factory dell ,ibm arrangments
that came out fully speedstep supported!
in that it resolves the typical (must use with factory working battery
in order to reach max speeds)instead one can decided if they want to run min or max speed with a single click of the button,no dramas,no driver issues,no complications once initially configured
thats how speedstep ought to be!

I think that the XP Supplemental files for the 600 series only address two items:
1. cstateflags registry patch
2. LCD colour profile

These patches were designed by IBM to be applied to XP on the 600 series. XP does appear to run fine without them, but I would nevertheless recommend applying these two patches to any fresh XP install, since that is what they were designed for. As I said earlier, I'm not 100% sure what the cstateflags patch does, but I know what the LCD colour profile patch does and in a clean install of XPSP2, the LCD display will not have a colour profile connected to it by default: you need to apply the LCD colour patch to add an LCD colour profile. Whether that colour profile makes will make much of a difference is another question...

I would not discourage people from applying patches recommended by IBM/Lenovo unless you've got a good reason. Just because XP runs without these patches doesn't mean they shouldn't be applied anyways.

i can understand if there is complications in xp with the 600e/x
but there ain't any without themsome patches.
that is no way implying that the software is utterly useless
but rather i prefer to run my laptop as i know it can.
my battery is nearly 3 years old now,i refuse to run ibms
reccomended power managment battery maximiser tools
instead configure the settings manually to let the battery
drain to the level its supposed to.
for the record i have used the patches and i can definetaly comfirm
they don't make the 600e/x run any worse.so its no problem either
way for me.
