T23 cpu ugrade 1.13 to 1.2...worth it?

Hi all,

Would this be worth it for the gain? I will already have the TP opened up for my wifi project and thought I might as well. One might be available, so I was considering. Would I have to worry about heat issues?

Thanks

This would be less than 10% in MHz, so i wouldn't spend money on it. If you already have a CPU, or it's dirt cheap, than sure, go ahead. Or if you seriously need all the power you can get.

Otherwise, i'd go with more RAM and bigger/faster hard drive.

As we've discussed before, the performance jump is negligible, but knowing you have the fastest (well, fastest you can actually get your hands on) T23 CPU is a good enough reason! 1.2 sounds so much better than 1.13...

Upgrading the drive to a 7200rpm model will have the most significant impact on improving overall performance and will probably cost less then a memory upgrade. I would definitely do the drive before the memory upgrade. A 60gb Hitachi 7200 ata costs $74 shipped at www.zipzoomfly.com.

LPC, I see that you too are "caught" in the upgrade game

I guess you are enjoying your T23.

Many people prefer the 1.13 Ghz CPU since the temps are a bit lower than when using the 1.2 GHz chip, esp since the performance gain is negligible. But as Dan (dsigma6) mentioned, knowing that your machine is maxed out gives you that nice glowing, satisfactory feeling

Thanks guys for all the input.....I think Gator hit the nail on the head......

how much higher temps on the 1.2? Enough to lower battery life? On my 1.13 i usually wont get past 60 deg C on full load and average in the mid 40 to mid 50.

I just bought a 1.2 for that maxed out feeling...

It shouldn't be much of a temperature change. Maybe a couple degrees at the most.

I have tested this upgrade while repairing a Fujistu Siemens 1.2GHz laptop and it is not worth doing it.
First of all- the overheating has become an issue, the fan goes off twice as frequently than on 1.13 GHz and secondly, which I consider big disadvantage, the battery life is reduced by approximately 10-20%.

Indeed all the memory upgrades, 7200rpm disks and faster processors hit the battery life quite hard and the gain is difficult to justify- perhaps upgrading memory is the only justifiable upgrade in my view. 5400rpm disk that is less then 6 month old will do the same service.

But the maxed out feeling is great anyways

10-20% battery life reduction for a .07GHz increase? I find that hard to believe.

Run the CPU on adaptive and it shouldn't really matter.

Or run it full speed ahead and keep TPFancontrol running at all times (Which I recommend using on every TP that supports it).

When I changed from 1.13GHz to 1.2 (Thinkpad T23), I didn't notice huge power consumption. The battery lasts nearly same as before, not even 15 min diffenrence.

Neither overheating was problem. But I rarely drive my machine at 100% load.

Edit. When I checked Intel specs about 1.13Ghz and 1.2GHz models, the second draws only 0.2W more power:

http://processorfinder.intel.com/detail ... Spec=SL5CL

Edit2. But I have to tell, that changing old Travelstar 4200rpm disc to 7200rpm was very huge improvement comparing to this cpu change. And that didn't shorten battery time significantly.

In my experience, T23s with 1.2 tend to run warmer than those with 1.13. No, I haven't bothered measuring the actual temperatures at the time, but I do remember that fact quite distinctly, although it's been a while...

Battery consumption has been on the equal side.

As with any machine, the key is what its intended use is going to be, and whether it fits for it...although 1.13 processor happens to be one of my all-time favourites, it has its limitations, and that's the case even more so with the video card involved...

If I were configuring a T23 for myself today, I'd max out the RAM, probably go with 5400rpm HDD and run W2K on it, if I were to stay within the Windows pallette...but that's just me.

awong · #13 Post by **awong** » Fri Oct 26, 2007 11:58 am

well my 1.2 came today going to put it into the r31, which has a worse video card than the t23, but will see how it turns out after I figure out this booting up two different hard drives (xp and ubuntu)

so yeah I think I maxed out this r31 that I think I should have maxed out a t23 instead, well there is always looking for a barebones t23 and making a 2nd laptop r31 with 1.13 for my sister

I did not spend really much time elaborating on this, I only noticed that the average runtime reported by the NHC (notebook HW Control) dropped from 2:40 to 2:15 with full battery while browsing the Internet with the CPU speed varying between 750 and 1200 MHz- it was running in dynamic adaptive switching mode. I should have run the battery calibration to get more verifiable results.
Also the temperature of the CPU was reaching the fan threshold faster and the laptop was running hotter. I do not know much about the variations in the CPU manufacturing process, it was one of the early steppings and the processor was one year older then the IBM's 1.13GHz.

I have a 1.2 in my T23 and the paint melted off the bottom. Wasn't too happy about it. It still runs fine and I've had it forever, it just has a bare metal bottom covering 25%.

#16 Post by **rkawakami** » Tue Nov 13, 2007 1:29 am

Paint melting off the bottom appears to be on the memory bay or MiniPCI covers. The CPU on the T23 is in the area where the product label is attached and I've never seen any T23 that has crossed my path which has paint missing in that area. Yes, the memory bay gets hot; probably hotter than than the bottom of the CPU since there's a fan (hopefully) operating on top. I've got mostly two, 16-chip 512MB modules in the T23s that I normally have been using and after several hours online, the memory bay is very warm. And yes, these are on 1.2Ghz systems.

I think on my r31, the rubber feet came off near the cooling fan b/c of the heat of the 1.2, I dont feel like taking it apart again, so I may hold off a while longer to put the 1.13 back in

Hi...
Is the 866 processor/system board capable and upgrading to the 1.1 Intel chip?
