Intel Celeron M to Intel Core Duo T2400

I have Samsung x11 laptop with Intel Celeron M 430 and i want to replace my old and slow processeor with something better.Heard that t2300-t2700 will fit and found one t2400 cheap..
But what do i need to know more?What should i do before and after changing processor?Update my bios?How?
My current bios:
BIOS Type: Phoenix
BIOS ID: NAPA0001.86C.0032.D.0612122018
BIOS Date: 20061212
BIOS Vendor: Phoenix Technologies LTD
BIOS Version: 06XJ
BIOS Size: 1048576
Chipset: Intel 27A0 rev 3
Motherboard Name: SAMSUNG ELECTRONICS CO., LTD.
Motherboard Model: SX11/SX12
System Name: SAMSUNG ELECTRONICS CO., LTD.
Base Manufacturer: SAMSUNG ELECTRONICS CO., LTD.
Base Product: SX11/SX12

 

Here you go: http://www.samsungpc.com/products/x11/x11.htm

 

I'd go ahead and do a socket M Core2Duo, like a T5200 or a T5300.

 

I had a T2500 (2Ghz) and then tested a T5300 (1.73Ghz) and the T5300 is much faster.

EDIT:
I checked the specs of your laptop ( http://www.samsungpc.com/gb/support/x11/specs/x11spec.pdf) and it was sold with 2 chipsets; the intel 940GML and the 945GML. If you have the 940GML you're out of luck. You won't be able to use a dual core CPU. If you have the 945GML you can.

PC Wizard ( here) should tell you wich chipset you have.

 

Mine is I945GM
Checked for the t5300 and t5200...I think t5200 with it's 1.6GHz would be a lil' weak for me...And t5300 is quite rare in aftermarket(in Estonia i have seen none on sale)
Is there any Core2Duo thats above 1.73GHz and would fit my laptop?
Edit:
Would these fit:
T7400 ; T7200 ; T5600 ?

 

There are x11 and x11c but mine is np-x11b...If i want to put now dual core processor,i need to put x11c bios ?

 

If you have an i945GML chipset you can use any of the following:
T2050, T2060, T2080
T2250, T2450
T2300, T2400, T2500, T2600, T2700
T5200, T5300, T5500, T5600,
T7200, T7400, T7600

For the bios, If you have the i940GML chipset updating the BIOS won't help.

EDIT:
x11 and x11c BIOS are te same. It is likely that the np-x11b uses the same BIOS as the two others

 

If i change my processor to core2duo,will i need to change cooler also ?

 

no you don't have to change it

 

T5500 SL9SH 1,66GHz/2M/667

Tomorrow wil buy this one and try...Lets see what happens
Do i need to update bios also?

 

Before buying it you need to confirm that you have the 945GML chipset. If you do buy the CPU and test it without updating the BIOS. If it doesn't work put back the Celeron, update the BIOS and try again with the T5500

But please check that you have the right chipset first.

 

I think the OP is mistaking the video chipset famiily with the motherboard chip, he says he has this:Mine is I945GM.
It is I assume is the video chipset number.

 

He's not. The the 945GM is the motherboard chipset which includes integrated graphics. The X11 can use either the northbridge's graphics or have a discrete NVidia graphics chip.

 

Now,from PC-Wizard 2010:
Chipset : Intel i945GM/GME
Video Card : Mobile Intel(R) 945 Express Chipset Family

 

I believe yours is a 945. Just to be absolutely positive before you potentially waste your money... run the Intel Chipset Identification utility.

 

Intel Chipset Identification utility = BS.
Shows like..5different chipsets.. ...or...or..or...Everest and pcwizard shows that i have i945GM and i will believe that.

 

just list it out... it is the most accurate.

 

As u wish.

Chipset

Detected Chipset:
Mobile Intel(R) 945GM/GMS/940GML Express Chipsets or Intel(R) 945GT Express Chipset


T5500 is 64bit and 34W,but celeron is 32bit and 27W..will it affect something?

 

it seems that you can go ahead and do the upgrade

 

Ok. Mine shows exactly which one I have ... but no... pretty much any socket M can handle 35w just fine. Just one of those will potentially get you some time knocked off your battery life.

 

Actually he would see an improvment in his battery live since the Celeron doesn't have speedstep while any of the above Core Duo & Core 2 Duo does

 

I didn't even think about speedstep, but that's very true. Plus, the C2D will be much more efficient than a Celeron anyway.

 

And unless it is 100% underload it will run cooler

 

The core 2 duo will run cooler for sure... even under load... newer architecture , smaller process (maybe) and speedstep.. What would we do without speedstep?

 

I can't even imagine that

 

T5500 now installed and working.Temp. is about 50-55'c..Is that too high ?
As i understand t5500 is 64 bit..Does my laptop allow now 64bit windows 7?
Will it recognize 4gb of ram now or mobo won't let ?

 

yes it can as long as ur chipset supports 64bit...also depending on chipset , 4GB RAM might work or not.. can u use Intel Chipset identification software and say what chipset u have?

P.S : i just found out u have i945gm... i don't think it supports more than 4GB RAM... but 64bit windows should work... i think.

 

There is more than just the chipset to know how much ram your laptop supports. Manufacturers can decide at will. In your case, the spec sheet lists the max ram your laptop is capable of supporting as 2GB.

 

At idle, those temps aren't anything I haven't seen before, though they are on the warm side. Nothing at all out of the ordinary though. Most HP's idle at that temp. And the 945 generally is limited to 3.12GB as the maximum amount of RAM because the chipset is 32bit, so it physically can't address 4GB or RAM, but to get the 3.21 you must install 2 2GB sticks. And yes, your T5500 will allow 64bit Windows 7, and even support VT-x for virtualization. I have a T5500 in my Acer 3680 and it performs very well, good choice with the T5500!

 

don't worry about the temperatures when your CPU is idle. What are your temperatures under full load?
You can use Orthos to stress your CPU and HWmonitor to check your temperatures. With a good thermal past and no undervolting yout max temperature should be around 70 to 75c. After undervolting it should be about 60 to 65c.

You can get orthos from here: http://sp2004.fre3.com/beta/beta2.htm

and RMclock from here: http://cpu.rightmark.org/download.shtml

To undervolt just follow this guide http://forum.notebookreview.com/showthread.php?t=235824

 

Max temp was 82'c on CPU
Undervolting didn't made any difference

 

Maybe ur not doing it properly... have u seen The Undervolting Guide?

 

Did it right as it was written in guide

 

I am trying to swap my toshiba a100's celeron 430 m with a Core duo t2400 but everywhere I've searched has said it cannot be done.

PCWiz2010 says I have socket 479 mBGA support

my chipset says: ATI RS400/RC400/RC410

Can it be done?

 

If you have BGA, it means the processor is soldered to the motherboard and is therefore not replaceable. I don't think that is correct, however. What is the full model name of your laptop?

 

Toshiba A100 - VA1
Model #: PSAAKC-VA104C

(From Canada)

 

Can you try to cpu-z to tell you what socket, processor and fsb it is running at? I really can't find a whole lot of info on the va1.

 

I uploaded the report to Drop.io:

http://drop.io/b0ua335/asset/jay-pc-html

Thanks for your help

 

Ok, you definitely have a socket M processor. Considering the other A100's with similar specs, it definitely sounds like you can upgrade to an early Core 2 processor using socket M, which would be far better than a Core processor. Any socket M T5X00, T7X00, or U7X00 processor should work with an update to the latest bios.

Wait, nvm. After reading the CPU-Z info, it says you have socket 479. However, according to Intel, the Celeron M 430 only came as a socket M processor. I'm confused.

Ok, looking into this even further, some socket M processors can function in socket 479, as apparently yours does. I would say an upgrade to any socket 479 core duo would be safe, but a socket M core 2 I really don't know, even though Toshiba seems like it may have done so.

 

The worst that can happen is that I try it and if not replace the CPUs back into their respective laptops.

Edit: apprently I have to go in through the keyboard maybe I'll wait for your go ahead before I do that kind of work!

 

Not all T7x00. T7200, T7400, and T7600. The T7300, T7500, T7700, and T7800 won't work.
U7x00 are usually soldered in the motherboard.

atonz:
You should be able to upgrade
Because you have an ATI chipset you can try the FSB/BSEL pin mod as explained here

you should also have a look at this. It might assist you to take your laptop apart

 

Well I'm having enough problems with the RAM I swapped. the 2x1gb kingston ram leave me with a blue screen when put in together while using (either) one makes it run fine. Suggestions?

 

I said socket M ones, the ones you mention are socket P. Also the U7X00 come in socket M.

 

Try swapping the ram around.
If you bought the ram second hand you sould test it with 'Memtest'. It is a freeware. Test one memory module at the time.

 

Each RAM stick works independently, and further investigation has me guessing that its simply Windows7 that is the culprit as the system runs fine with various Linux live CDs.

Anyhow, my fan randomly stopped working so I pulled the laptop apart and cleaned it and the heatsink out. Also snapped some of the clips holding the ribbon cable for the keyboard etc. The fan now runs (dust was clogging it) but now the LCD won't turn on so I'm going to cut my losses and head over to a shop today and maybe they'll have a chip to upgrade it.

 

sorry to hear about your troubles. Few things though:
1- Not all latptops are configurated the same way. Some of them have the fan spinning constantly, while for others the fan spins only when the temperature goes over a predefined value (usually between 45 and 50c).

2- you can make the keyboard riddon a bit thicker using selo tape. This should allow the ribbon to hold in place without the clips. Also once you put the ribbon inside its socket you can use more tape to secure it in its place.

3- have you tried your laptop with an external screen?

4- Have you tried memtest? in it's availabale in most linux livr CDs? That would help you to confirm that the problems that you had before with 7 are not memory related.

 

Hey thanks for the reply, maybe a late post might help me out since I'm still experiencing the dual-ram problem. I swapped RAM with another Toshiba laptop which had 2x1GB Kingston RAM sticks. My laptop boots fine when only one 1gb stick is inserted. It does not matter which 1gb stick or what slot it is inserted into (there are two slots).

When two of the sticks are inserted I either get a Blue Screen of Death shortly after login to Windows or Flashing caps lock when booting into Linux/Linux LiveCD (which instantly freezes linux regardless of its state).

What is wrong!? If each stick works individually, no matter in what slot, it appears to me that a) the RAM is fine and b) the slots are fine. So why won't they work together? Given this info is burning memtest to a cd even necessary?

Here is a CPUZ report of my laptop with the old 2x512mb RAM:
http://drop.io/b0ua335/asset/jay-pc-html

 

It seems that I was not wrong when I suspected that the ram you're trying to use is incompatible with your laptop. Check the following link:
Ram problem with a100-011 - Toshiba Laptop Forums
The following Kingston modules have been tested and worked in the Toshiba a100:
KTT533D2/512
KTT533D2/1G
KTT533D2/2G
KTT667D2/512
KTT667D2/1G
KTT667D2/2G

Have you tried 512MB + 1GB?

 

I hope it's okay that I continue in this thread, even though its off-topic. I really appreciate that info because it eliminates another possibility. The 2x1GB Kingston sticks I have are KTT667D2/1G @ 1.8V, which is on the list you provided above.

Also note that if I have the two sticks in when trying to install windows 7 I get a BSOD after setup files load.

Any other suggestions?

 

Try going into the bios and loading setup defaults if you haven't already done so. It's one of those things one should always do when changing the ram configuration but many forget to do so.
