I have a T22 and I am not intending to up grade the processor. The highest speed is 900Mhz @ 100FSB. Your processor is 700Mhz hence a increase of 200Mz is not worth the troouble.

I suggest you wait for a good and cheap T40(1.5 or 1.6G) and upgrade to a 2.1G or 2.0G, then you will get a very fast system. I am just doing that. I am waiting for 6-12 months for T40/41/42 prices to drop about $300-500 from their current prices.

To upgrade your processor.....u need to change the fan as well. The maximum processor upgrade would be the 1000 Mhz ones. But I'm not sure you can get it or not....
However, I would not recommend this upgrade........and not worth it as mentioned by ttan98. His recommendation is much better...

43% increase (700-1000), P-IIIs are cheap (<$30) = not worth it??? Wait a few more years and you can get a T60 for a few hundred bucks, or you can spend a few bucks now to put a little more zest in yours while you wait. JMAO

If were to put a little more "zest" into it...what model # of PIII 1000ghz should I get is the biggest question??? I am trying to upgrade the girlfriend comp, cuz it's just a little sluggish for me. And she's actually complaining about it a bit. So I thought it'll be fast enough for the next couple of years if I do a upgrade on it now...It's just a surfing and word processing comp....

hello

i was wondering about jumping up to 1.oghz as well but wondered what the code no is also if there is a better stepping to be found i have been reading about the 133/1.3 with 512k cache... yes 100/256.. i no that you would drop speed but maybe the extra cache could really help.

I don't think a 133 would work...it's gotta be 100? doesn't it?

Someone for the love of god! PLEASE HELP!

I believe an SL5QV should be the right 1.0ghz CPU but I would need to know the sSpec on yours to be certain.

You definately need some more ram. I would suggest adding a 256MB stick into your machine. A faster HD (also larger) would add to the serviceable life of the machine.

will the thinkpad t23's cpu fit in the socket on a t21?

Take a deep breath!

To be honest there is a wealth of knowledge on this very board about T2x CPU upgrading. There may be an apparent lack of help as most are thinking "use the Search button" !!

Anyway, it's not often I can say "been there, done that" on this illustrious forum but in this case I have. You require a Mobile Pentium III but it MUST be the 100MHz bus model. 1GHz is as high as you can go. Technically, the voltage requirement is slightly higher for anything above the 850MHz but I have had no problem with that.

I went for the SL5TF though I have a feeling the SL5TB or the SL54F would have been fine. The Micro-PGA2 or BGA2 package is required. It's POSSIBLE the 495 pin package SL58S and SL53S might fit but I wouldn't risk it.

Quick check of Ebay reveals 3 x SL5TF's but I see they are still fetching quite a decent price ~ $65. Ah, the wonders of the free market - I saw a Mobile Pentium M (Centrino) 1.7GHz go for the same price yesterday!

Now, heat. You are going to be generating substantially more for your T20 to cope with. The fan really should be upgraded. Again possible but for a price. Despite upgrading my fan/heatsink when my 1GHz is running full tilt the temperature gets really quite (impressively/worringly) hot - there is no way I would want 100% load for any sustained period of time.

So, should you do it? From experience I'd say yes if you 'just want to' or 'because you can' but to be honest the RAM/hard drive combo is a better bet as is often the way.

Jonathan, I completely agree. If you can get a dirt cheap 1GHz CPU for the T20 it would make sense to upgrade. The problem is the thermal compound of the T20 (which is crap and must be trashed).
You then have to get the T22 Fan unit. Heat is no problem with the T20 and the old heat sink, but your fan will run most of times.

I have done this many times. Currently I gave my old T20 to my father. It has a 1Ghz CPU, T22 Fan Unit with the heat transfer spring to the keyboard and it is dead silent most of times.
Again, WinXP needs 256MB Minimum just to run itself, anything below is a waste of time.
You will never get the T20-T22 up to speed, not even with a fast drive. suggestions otherwise are foolish. The problem is the limited I/O data rate of the Intel BX440 chip set. A 4200 rpm drive is the best and it is dead silent.
However, if you upgrade to the T23 motherboard, you have a VERY different beast. A 7200 rpm here is very nice. Data throughput us vastly higher. Of course, no DDR Ram, but still, it is very nice to work with.
Actually, to most of my friends, I recommend to dump the T20 on EbAY and make the cheap upgrade to the T23. You can even keep your hard drive and everything on it installed, just plug in the drive and let the hardware be recognized.

Getting a T23 upgrade on Ebay is a very cheap solution, most of the time the systemboard is already in a base, drive caddys and cpu's included. Your old hardware is interchangable, sometimes even your PC100 ram works too.

BossTone74 · #15 Post by **BossTone74** » Tue Jan 24, 2006 10:43 pm

WOW you guys are a wealth of information!
It's really making me think twice about doing anything...

PC100 will not work in the T23.

AbsoluteRaleigh · #17 Post by **AbsoluteRaleigh** » Wed Jan 25, 2006 9:52 am

A 900Mhz will work fine w/out a new fan. Code: SL53T. They're $19 on eBay. Installing a T22 fan will offer a little additional cooling. A 1Ghz SL53S offers a little more performance however they go for $40>.

betabill · #18 Post by **betabill** » Wed Jan 25, 2006 12:42 pm

PC100 will not work in the T23.

Read some prior threads. True, just like overclocking memory, it's a crapshoot but I used 2-256meg PC100 on my T23 last night just to see how stable it would run. Could have save some money if I had tried that before I bought 2-512 PC133.

hello

i just got a 1.0ghz sl5 tf , old fitted was 800 ist boot was start up screen then there after it gets warm but no screen etc my bios is 2003 march ,feels like a bios problem any ideas its a t22 384 ram 80gig samsung dvd burner , o/s xp pro been running fine . still ok with old cpu

thanks ianf

djpharoah · #20 Post by **djpharoah** » Mon Feb 06, 2006 6:25 pm

you sure your 1.0Ghz cpu shares the same voltage demands as your original 800Mhz cpu?

cuz if the 1.0Ghz needs more voltage, then it will not work in your motherboard.

ianf · #21 Post by **ianf** » Mon Feb 06, 2006 7:35 pm

can't say but if the the board gives 1.65v at the core ,speed step will surely clock cpu to say 750 . have updated bios so still no go my board is a t22 bios is latest for that board i ID it at lenovo i will cotact seller from ebay see what he can suggest . ianf..

i noticed jonathan w fitted this type hope he has some input also what board ver he has ..

JonathanW · #22 Post by **JonathanW** » Wed Feb 08, 2006 7:30 pm

Hi Ian (I presume!),

Yep the SL5TF is what I went for and it was a drop in replacement. My first thought/concern is that your CPU is faulty.

Only real way to see is pop it into another machine which I appreciate may be easier said than done. I put my SL5TF into a T21. You have a T22 which in my opinion rules out the compatability question - it definitely is. I'm afraid my vote is for duff CPU, sorry.

I can't check my board revision at the moment as I am in Sydney for a while with only my X31 for company!

thanks jonathan w

great place sydney just a very long flight , i think its dead as well the guy i bought from on ebay seemed happy to change it although he is in poland.
i wish the bios was a little more tweakable . i upgraded to the newest bios from xp it was the simplest ever

ianf

yes ian

djpharoah · #24 Post by **djpharoah** » Fri Feb 10, 2006 12:45 am

anyone know if once you put in the 1.0ghz cpu into the T20 does the bios recognize it as a 1.0ghz cpu w/ speedstep?

i remember trying to use amd xp-m cpus on amd motherboards and they couldnt determine the cpu speed

It will recognize the 1G as long as you upgrade your bios. Mine only read 800 and 128 of ram until I upgraded the bios. Now it reads the 1G and 512 RAM.
