CPU upgrade T30

[Kyocera]

My t30 has a gig of ram, a 72K60 hd and the 1.8gig cpu, is there a plug and play cpu upgrade to say 2.0ghz?

[dsvochak]

Is this any help?

Yeah, looks like i wouldn't gain much, I'll just leave well enough alone.

You can actually go all the way up to a 2.4gGHz. Some have even said 2.6GHz.

2.6GHz. I've got one in my A31p and have toyed with the idea of throwing it in my T30 just to see the result.

Costs a fortune on eBay, if you can find one!

have a 2.6 ghz sl6wz running but wouldnt recommend it. fan runs a lot more, temperature runs up to 85°C. got the supposedly larger "fan 2" that was used for models above 1.8ghz the other day, which is IDENTICAL to the "fan 1" i had installed. so that won't help either... or maybe ibm sent the wrong one.

the gain in speed is remarkable. huh the processor expensive? i paid ~100 USD for it?!

IBM sent you the wrong fan!

US$100?? Buy all you can and sell them on eBay US!

You could easily triple your investment.

Ditto!!! Either you had some serious patience, or no one else bid on it. Great price!!

[censored]. i already put the fan in. it has fru 46P3132 on it, yet is no larger than the original. the one i took out has 46L4753. THEY ARE THE SAME. which one do i need to get?! and where? do you think it would reduce the heat?

the deali got might have been an exception?!

Same size housing, different fan inside. Supposed to run faster. A judicious application of Arctic Silverwill bring the temps down!

Apparently not a lot of demand for them over there, so I'll have to keep checking eBay.DE for more.

There'a a 2GHz one with two bids and it's only at EUR 2,50! Another 2GHz is at EUR 20,50.

Watch out for german sneakiness though. I 'heard' a lot of people 'might' be using sniping software...

Thanks for the hints. Yeah I used Arctic Silver 5 this time. Havent 'felt' any change yet though. Then again people say it takes 200 hours uptime until it works up to its potential.

hey, has your overactive fan calmed down a bit by now? i'm looking to do this t30 cpu upgrade too. i'm zeroing in on some 2.4 ghz p4-m's, but i kinda like the peace and quiet of my relatively cool and slow 1.6ghz chip. if the arctic silver 5 helps to keep the fan unobtrusive, then that will throw things in favor of the 2.4-2.6 range of chip.

otherwise, what useful stat is the nominal heat output for these chips? is there much heat output difference between a say a 2.4ghz chip and a 2.0ghz chip? how about a comparable 2.4ghz celeron?

[danage]

unfortunately, no. the fan runs almost constantly now. even though there is a slight noticable gain in processing speed, i am planning to downgrade. compared to the benefit, it's just not worth having the annoying fan running all the time. plus, i get less battery life.
i heard upgrading the hard drive will bring large improvements, so this is probably what i'll do.

that's too bad. what chip did you have in it in the first place again? i'm looking at my cpu history, and i peg it at 100% regularly. i'm just running a 1.6 though. i wonder if a 2.0 or 2.2 would run any cooler.

upgrading to a 7200rpm drive really will do wonders. that was one of the first things i did. remember though, a 7200rpm drive also runs hotter and sucks more energy too. i mostly run plugged in so battery life isn't much of an issue for either the hd or cpu, but i do like the mostly quiet fan though...

[JHEM]

remember though, a 7200rpm drive also runs hotter and sucks more energy too.

That, simply, isn't true.

Any increase in heat output would be negligible and hardly noticeable, at worst.

Any increase in power consumption is offset by the increased data transfer speeds. A 7K100 will use LESS power overall than an ancient 20GB 4200RPM Travelstar.

Taken directly from the datasheets on Hitachi's site and assuming that these marketing blurbs are accurate:

7K100 Current specs:

Code: Select all

Startup (peak, max)     5.5W
Seek                    2.3W
Read (avg.)             2.0W
Write (avg.)            2.0W
Performance idle (avg.) 1.8W
Active idle (avg.)      1.1W
Low power idle (avg.)   0.85W
Standby (avg.)          0.2W
Sleep (avg.)            0.1W

4K40 Current specs (couldn't find specs for the 20GB):

Code: Select all

Startup (peak, max)     4.7W
Seek                    2.3W
Read (avg.)             2.0W
Write (avg.)            2.1W
Performance idle (avg.) 1.85W
Active idle (avg.)      0.85W
Low power idle (avg.)   0.65W
Standby (avg.)          0.25W
Sleep (avg.)            0.1W

So overall, about the only time that the 7K100 drive is using less current is when it is in "performance idle" or standby (and it's a very small difference). The major difference I see is the "Startup" current. The 7K100 drive can consume almost 20% more current when spinning up than the 4K40. This means that if you sleep the drive when using battery power, you will be using MORE power to start the 7K100 over the 4K40. In short, your disk drive's current usage (and the battery's runtime) depends upon how you've setup the power management features of the operating system.

I couldn't find any specs about the temperature profiles of the drives but generally a piece of equipment which uses more power will run warmer than one that uses less power. Energy has to go somewhere .

[_erazor_]

you may not forget that a 7200rpm driver loads stuff faster than a 4200rpm one, too.

so while it may actually use a bit more power WHILE it is loading/writing data, it`s done with the job a lot faster and in retrospect uses less total power cos it doesn`t "seek" and "spin quickly" as long simply because the same job is done quicker.

You really can't equate the 4K40 with older drives as it has benefited from all the latest drive technology, e.g. fluid bearings and pixie dust platters.

20GB DJSA220:

Startup (maximum peak):         4.7W

Sleep:                          0.1W

The Wattage draw for the DJSA-232 32GB HD that was common in the same time period is 20% to 25% higher than the DJSA-220 in all categories!

Here's the tale of the tape for the old, beloved 6GN HDs so many are familiar with from their 600 series machines:

Startup (max peak)              4.7

Only if more energy is actually being consumed! Other than at startup, a 7K100 doesn't use any more power than ancient 4200RPM HDs, and in some instances uses less.

Which is exactly my point. If one chooses to power down the disk drive after the 3 minute idle time which Windows XP and 2000 have built into the "battery only" power management functions (like I do), then overall, as the user cycles the drive off and on, the average current comsumption will be higher using the 7K100 drive vs. the older, slower drives. This of course assumes that the user would be using the system in the same way regardless of which disk drive is installed in the laptop: surfing, taking a break, working a document, taking another break, etc.

...and in some instances uses less.

Agreed. If one uses the 7K100 drives he/she would be better off leaving the drive powered on at all times when running on battery only.

(edit: My comment about the "7K100 drive vs. the older, slower drives" being higher in current draw is in reference to the original 20GB drive that James gave as an example. If compared to the 32GB DJSA-232, then yes, the 7K100 is lower in power in all modes, except for startup.)

i upgraded my t30 over the weekend to a 2.5ghz SL6P2. i used that arctic cleaner 1 and arctic purifier 2 stuff that arctic folks recommend to clean off the "new" cpu ( my fan was on the fritz so i got a new one of those, so no need to clean it). after i used it, the chip was mirror clean (apparantly there was a lot of crap on it).

i used a liberal amt of as5, and, while my cpu temps are up, they have come nowhere near 85C. i was running some apps that had the cpu living around 90-100% for about 10 min and i only got up to about 72C (not sure if it plateaued or not though).

other than that, i "average" only about 50C-60C, depending on what i'm doing. (when it comes out of suspend, mobilemeter sez about 38C). sure, the fan is on pretty much all the time, but maybe it just doesn't bother me...

did you use that arctic cleaner stuff? it may make a significant difference.
