I have just upgraded my t40 from p-m 1.3g to dothan 1.8g

the dothan is so great. It works perfectly. I bought this item in ebay for $320. It's much cheaper than other places. I suggest to upgrade ur laptop's cpu. If u have any questions u can email me or we can discuss in msn.

Why??

Most CPU's in machines less than 2 years old are perfectly adequate for everyday use and will still be good for the next few years. If you want more power and think wasting money to gain a few extra 100MHz is a great idea you should have been using a desktop PC in the first place.

Whooo Nice!!

I was thinking about doing that..

Could you bring some more info.. was i easy?
I thourght dothan use less voltage,
does the motherboard step down correctly?
How are the temperatures?
Is the fan more on now?

Maybe the OP can post some benchmarks - I assume he's seen a significant speed increase. While I'm inclined to agree with you on laptop upgrades, $300 is a lot cheaper than buying a new laptop and a 500MHz jump for that price doesn't sound like a "waste of money" in all circumstances - assuming the other components could keep up, it could mean the difference between being able to run HD media or smoothly multitask a few more applications. And if you could ebay the 1.3 for a modest amount, it would further subsidize the cost.

Sure it's not for everyone, but nice to know it can be done. I might not mind replacing the 1.8Dothan with a 2.5Ghz/4MB cache next-gen CPU in a couple of years

it's easy to do but u should be careful.
the motherboard steps down correctly and the temperature is about 48C,when i'm listening to the music and seeing some websites.
When I playing the game like counter-strike it's about 57C.
when u upgrade the lateset bios edition the fan is more than before.

Could you post a .txt. dump from say CPU-Z 1.24? www.cpuid.com
And also the motherboard and 855PM infor (revision)? CPU-Z can write all this information into a txt file.

Did you apply thermal paste anew after replacing the banias with the dothan?

And do you see higher temperatures now or the same?

FInally! Does enhanced speedstep work fine? Is the CPU normally at 600MHz and only scales up to 1800MHz only when needed?

when i use the battery CPU normally at 600MHz
the higher temperture i have seen is 59C

yogijalla · #9 Post by **yogijalla** » Thu Oct 14, 2004 12:01 am

Have you checked the voltage? (the dorthan is less than banias)
How is the speedstepping with the new proc?
Also can you tell how the fan behaves?
- is it generally more noisy than before?
- does it come on during surfing (at 600mhz)?
- does the fan stay on low speeds or go directly to high noisier speeds?
Any idea about change in battery performance?

Thank you... i think im going to try this...

darkhelmet03 · #10 Post by **darkhelmet03** » Thu Oct 14, 2004 12:19 pm

What model number is your T40?

As the previous person said it would be interesting if you could neasure the voltage supplied to the dothan and if [censored] is identical to that suplied to a dothan in a new T42 machine....

muffd · #11 Post by **muffd** » Thu Oct 14, 2004 12:32 pm

Congrats on the upgrade! I think now to make your notebook perfect you should think of purchasing the 7200 rpm hd. Your T40 will scream!

wei313 · #12 Post by **wei313** » Thu Oct 14, 2004 1:53 pm

yep, i want to buy a e7k60 for my t40. it's about $165. Can anybody found a much lower than $165? tell me please

JHEM · #13 Post by **JHEM** » Thu Oct 14, 2004 2:50 pm

$120.71 from Dell Small Business.

I'm a student. What should I do to get this good price?

bdomz · #15 Post by **bdomz** » Thu Oct 14, 2004 4:07 pm

I got the Hitachi drive from Dell small business at that price. They delivered to my house, they'll ask for a business name at checkout. My roomate actually owns a company so I put it under that name but you could probably just make up a corporate name.

muffd · #16 Post by **muffd** » Thu Oct 14, 2004 4:35 pm

Just use your last name as the company name. They don't check to verify you are an actual business owner. Don't forget to check the box saying you will not re-sell this hard drive.

While you're at it, you can call IBM and tell them that you ordered a new hard drive and they did not send you the recovery disks if you don't have them already.

RoadHazard · #17 Post by **RoadHazard** » Thu Oct 14, 2004 5:34 pm

Wow cool. I would like to know some benchmark as well. Not that everyone should do it but for slower CPU like 1.3, that may be a way to go to replace it with a 1.8 or faster. I might do the same thing but I want to wait until I'm out of warranty first.

wei313 · #18 Post by **wei313** » Thu Oct 14, 2004 7:12 pm

the 7k60 of dell's price is much higher now. unlucky.
I want to buy the E7K60 instead of 7k60.
the best price of E7K60 I found is $165

muffd · #19 Post by **muffd** » Thu Oct 14, 2004 8:40 pm

If you go to www.bensbargains.net there is a post there about the drive for $120

wei313 · #20 Post by **wei313** » Thu Oct 14, 2004 9:31 pm

i can't buy it with the best price $121. I think I miss it .Now i'm searching at ebay.

I think the E7K60 is designed more for rack mount servers, the 7K60 is designed to work at higher temps so is probably the best solution for a laptop. People seem to use both though and I haven't actually heard of any problems yet.

PaulB · #22 Post by **PaulB** » Fri Oct 15, 2004 3:58 pm

Any other difference between the E7K60 and 7K60 ?

wei313 · #23 Post by **wei313** » Sat Oct 16, 2004 12:02 am

I bought the 7k60 from ebay. the price is 137.5 including the shipping fee.
My t40 will be more powerful.

darkhelmet03 · #24 Post by **darkhelmet03** » Sat Oct 16, 2004 12:11 pm

Hi wei313

Could you download sisoft sandra benchmark http://www.sisoftware.net/ and post your scores for the CPU, multimedia, arithmetic and memory bandwidth scores?

In addition the score for filesystem performance (measures HDD speed) would be highly interesting with the 7k60 since I am also considering going to 7200rpm in the future.

Thanks!

i have a T40 2373-RG9 which is 1.3ghz, whats the "limit" on cpu upgrades for this type of laptop?

will it accept any of these:

wei313 · #26 Post by **wei313** » Thu Oct 21, 2004 9:35 pm

the 2nd one is an Intel® Pentium® M Processor 735. Mine is 745. Both of them can be used for the t4x.

skanky · #27 Post by **skanky** » Fri Oct 22, 2004 1:39 am

is it easy to change the processor. i recently took my T40 apart to install an atheros a/b/g card which wasnt too hard but is the processor upgrade anything like replacing the cpu on a desktop? ie, pull a lever which raises the processor out of the housing or will i have to do some levering to get it out?

thanks.

wei313 · #28 Post by **wei313** » Fri Oct 22, 2004 9:04 am

I think it's not hard to change the cpu. But you must be careful.

there're some pics. You can know how to change it.

skanky · #29 Post by **skanky** » Fri Oct 22, 2004 10:48 am

are the screws that hold the fan assembly above the processor held in with normal screws or ones that require an allen key of some sort?

nikemen · #30 Post by **nikemen** » Fri Oct 22, 2004 4:29 pm

So, the new 2379 DXU's that I bought my oflks, are 1.7 m DOTHANs, I have a 1.4 m in my 2374 4GU. I bought it about five months ago, actually it is a t41

Can I simply open up their machine and swap out the processors? How hard is this, and what has to be changed? Do I change settings in thte BIOS, or will it simply read the new processor?

What about FAN and CPU stepping. Will it just work and understand the speed and temp restrictions of the new processor? That would be pretty sweet, and they wouuld never know the differance.
