Intel Mobile Processor Compatibility Guide

Your system will not understand the 1066MHz FSB, because the BIOS does not support them. Even if the BIOS recognized a T9800 at 2.93Ghz it would only run at 2.2Ghz because the system can only run a 800MHz FSB.
Your best bet is to upgrade to a socket P SANTA ROSA cpu like the T8300, T9300, T9500

K-TRON

 

like k-tron sayed on the example with the t9800, the cpu doesn´t just start with fsb800? i mean, desktop-cpu´s with fsb1066 can also run on fsb800 systems with a limited performance, reasoning on the lower fsb...

 

Sadly, laptops just aren't as flexible as desktops. Period.

 

I can confirm that the HP 6720s doesn't support 1066MHz FSB CPUs.

 

I have a new question... I upgrade my notebook with the system-board of a 6730s, which has gm45 chipset and can handle fsb1066... but do I need ddr2 with 1066mhz or can I still use my 800mhz modules? desktops can handle ram with a lower clock, but I don´t know how this works with laptops

 

Notebooks can also handle RAM with a lower clock.

And there are no DDR2-1066 SODIMMs available.

 

so I thank you very much... after these infos I can now upgrade my notebook 6720s to the next higher model 6530/6730s with the GM45 chipset

 

Thanks for the Info.

So will a T7250 (socket P) work in Socket M 945/940 chipset?? since they both used 479 socket??

 

No
Socket M processors have a different electrical pinout than socket P processors. A T7250 will not work

A T7200, T7400, and T7600 will work, but they are rather expensive processors.

awesome thread

 

is the list of processors still up to date? I think I didn't see the P8300...

thanks for doing all that, btw.

 

Hello!

I already posted in another thread, but i´ve found this one, and one guy here that says it has his l40 upgrated with a T8300. I post the same message here to see if anyone can awnser me.

[[]]

 

It's fairly up to date. I've got everything through the T6400/T6600/T4200. I don't think the P8300 is officially released yet.

It means that your GL960 or your BIOS simply wasn't able to take the T[5570?] (no such thing as a T6570). You've got to remember that the GL960 and GL960 laptops officially only support 533MHz FSB Celerons and Pentium Dual-Cores. Most will be able to run 667MHz FSB and 800MHz FSB Core 2 Duos without any problem, but it is always partly a crapshot. It has nothing to do with the memory speed, or the chipset itself; you are trying to run it beyond it's official specs, and it's not working.

 

Well, it exists T6570, and i have exactly one SLGLL in my hand.

I guess ill try to buy one 667fsb cpu..

 

Jesus, Intel just keeps pumping out these super-obscure processors...

Knowing that, I'd actually hold onto it for a bit until your next BIOS revision. The thing might just be too new. BIOS revisions probably won't ever provide official support, but it might tweak some random setting that'll let this thing run.

Even if you scrap it, I think you still have a chance with an older 800MHz FSB processor... but again, it's always somewhat of a crapshot.

 

This is in relation to upgrading a T6400 p7350 Penryne socket P (478). Whats the max upgrade it will take. Does die size and fsb have to be accounted for. from cpuz150 it tells me i have a p7350 but these run at 1066fsb and the 2ghz proc. is running 800fsb. this is a 45 chipset on a asus f8va. im confused will this chipset take cpus with 1066fsb or quad cores.

thanks.

 

This is such a useful thread and should be sticked IMHO.

Especially with the diy notebooks now

 

Very technically detailed topic, thank you very much Commander Wolf for such helpful info, I really learned alot..

 

yup, that was me. I upgraded my Toshiba L40 - 14N with a T8300. This will only work with the 14N and the other L40's with the 960GL /965GM chipset (a few other people I know have the L40 - 12K model, which has a 945 chipset). It still works like a charm for me, running at 800MHz FSB and 2.39GHz per processor (after installation of a processor state regulator, RMclock in my case).
Windows XP has the bad habit of trying to downclock processors as much as possible, occasionally supplying a too low voltage even for the 'SuperLFM' low voltage mode. when I tried this state with my L40 after upgrade, it crashed / froze in a similar manner as described above (after usb init). The answer to this little hiccup is to make sure your processor gets enough juice (again, with a processor state control prog, disabling this low voltage function),

If you need any help, you can contact me (I'm a total forum newbie myself, and really don't know how to achieve this / that)

 

If you have a 45-Series chipset, you can use any Socket P processor (including those with a 1066MHz FSB) with the exception of quads and extremes. Due to their higher TDP, the quads and extremes are not or unofficially supported on most 45-Series machines, and will most likely not work in a smaller machine like the F8VA. The only way to know for sure is to try it though...

The T6400 is relatively new so CPUZ may not be able to recognize it yet.

 

Awesome, thanks for that. So it will take a T9800 further down the track, when they become cheaper. Would it be worth upgrading to ddr3 ram at the same time or not worth it.

As you can see this f8va is a cut down version with the T6400. Is there any possibility the chipset may be downgraded. Is there only one version of the pm 45 express chipset.

cheers.

Edit: just read this. only GM45 (Intel® GM45 + ICH9M-Enhanced) will support DDR3 not PM45

 

The problem is that it freezes before i can do anything about it. I´ve already disabled the dinamic control of the CPU in the bios with the older processor and instaled the new one, and nothing.

 

No, no, that's not how it works. All of the 45-Series chipsets can support either DDR2 or DDR3 memory, depending on what the manufacturer implements. If you currently have DDR2, you're always going to have DDR2; if you have DDR3, you're always going to have DDR3. There isn't much a performance difference anyways.

As for the processor, yes you can use the T9800. There are multiple versions of the 45 chipset, but all will support any Socket P processor (I'm not counting things like the 40 and 43 chipsets here). It is unlikely Asus with put an older chipset in their cut-down version of the f8va. It almost certainly uses the same board as the higher-end models.

 

Hi all this is my first post in this forum ... actualy i made this account so i can fire one BIG question . I have an ASUS A6Ne with Intel 855GME and pentium M on mPGA479m .... can i change this with a T2080 ?
Mothereboard seems to support fsb533 for my T2080 but i don't know if the 855 chip will react with this change ... so i could use some advice if i should give it a try .
Thanks.

 

All flavors of Pentium M use Socket 479. The T2080 uses Socket M. They are mechanically and electronically incompatible. You absolutely cannot use a T2080 with an 855-Series chipset.

 

mecanicaly they are compatible .... don't know about ... the other part . thanks for your answer i will wait for Asus response as well ... Realy don't know wat to do
T2080 use mpga478mt known as socket M ... don't know if my A6Ne board is supposed to use/support it but T2080 fits well in my socket
------------------------------------------------------
Thanks for help wolf .

Asus poor response ...

"Thank you for contacting ASUS Customer Service.

My name is Shearly and it's my pleasure to help you with your problem.
For the CPU, laptops' cpu have been designed to be modules (able to improve the produce efficiency. ) Though they have the same port, but they don't have the same circuit. The ASUS laptop's motherboard are all different, they can only support the special cpu, so I'm afraid that you can not change it for the moment. Sorry for the inconvenience.


Please accept our sincere apologies for any inconvenience caused."

 

Why not get a T7xxx series?
Great cpus 4mb cache.

 

I don't know if you're being sarcastic, but a T7x00 processor won't work in his laptop. Just maybe that's why he's not using or going to use one...

 

hi,
i've a lenovo R61i with T5450 cpu and 4 gb ram. i'm mostly using flash, photosop and illustrator and i can feel when the cpu in stress.. i want to upgrade the cpu for t9500 or t9300 but they are too expensive.. maybe a t7500 (around 120 at ebay) but i'm not sure if it is worthwhile or not?
thanks in advance..

edit: with intel 965 express chipset..

 

Well, whether it's worthwhile or not is really going to be more of a personal decision. If you're really feeling a slowdown due to CPU speed, it's most likely worthwhile to get a T7x00 or T9x00 processor. If your bottleneck just happens to be elsewhere, then it most likely won't be worthwhile...

 

Hi guys,
I've an Asus A6JA-Q039H, with Intel 945PM motherboard.
I want to upgrade CPU with an Intel T7200, but I found that it comes with two different sockets:
SL9SF: socket M with 478 pin http://www.cpu-world.com/sspec/SL/SL9SF.html
SL9SL: socket M with 479 pin http://www.cpu-world.com/sspec/SL/SL9SL.html

are they both compatible with my laptop, or should i buy only the SL9SL?

 

SL9SL is a BGA chip, meaning it's supposed to be soldered to your motherboard. That won't work, but SL9SF should work fine.

 

would a T5250 work in a dv4t? It uses the pm45 chipset. I would think so, but need to check before getting one.

 

Intel has just released T9900 C2D. 3.06GHz, 1066 FSB and only requires normal 35W TDP. The same with the other member of regular C2D.

http://processorfinder.intel.com/details.aspx?sSpec=SLGEE

I think the original thread needs to be updated with the new CPU.

 

It should work, but if HP doesn't expect anyone to stick a T5250 in a DV4T, the BIOS may not support it. If it's a stock option, compatibility should be guaranteed.

Added the T9900 along with some other SL, SP, SU processors.

 

thank you, commander.

so i'm going to buy T7200 SL9SF.

 

are there any quad-core processors that can work in a PM45 chipset?

 

Q9000. Q9100. QX9300. I don't think Q9200 is out yet, but it will be soon...

 

^ so can I assume, based on your quote, that I couldn't pop a Q9000/9100 in place of my T9600? it would need a special Mobo/bios to work?

 

The only way to find out is to try it yourself or to find someone who's tried it him/herself. It's more or less a crapshot; sometimes it works, sometimes it doesn't. I haven't heard of such an upgrade actually messing up anyone's system, so I'm fairly certain it'd at least be safe to try.

 

understood. thank you for the advice. I wish Sony offered one as a configurable Vaio AW. that would have confirmed it for me. seems like an expensive gamble. something to think about, though. thank you for the advice.

 

hi i am new, i read this thread attentively and i am pleased to find such detailed thread because i want to upgrade the cpu of my dell inspiron 1420.
the current cpu is a core 2 duo t5550 (1.8ghz/2mb/667)
the chipset is a gm965

i want to upgrade to a t9300 and i am not sure that it will work, cuz from my experience the dell pc are very very incompatible, no overcloak, everything is hidden ...

so please if you can advice me if i can do it or any alternative if i can't. thx

 

The T9300 will work in the 1420. Just make sure you have the latest BIOS.

 

thanks a lot for your quick answer Commander Wolf and i ll go to buy the t9300 in peace
is it risky to update my bios ? if you can link me a tuto to update dell bios it will help. ( i ll google in my side but i want one adviced by you too )

 

Will a P8400 fit and work in a laptop that now holds a T2390 ?

The laptop is a Asus F7SR.

Thx in advance.

 

I have:
======Toshiba Satelite m105-S3001===========
CPU: Intel Core Solo T1300 @ 1.66 Ghz (Yonah)
Chipset: Intel 945 GM Express
=======================================
I would like to replace the CPU with:
--- Intel Core 2 Duo T7200 @ 2.00 Ghz. (Merom)
Is this a simple Remove and Replace procedure ? My main concern is that the Merom chip is 64-bit. I dunno if the 945 GM express chipset will handle 64-bit Chips....
Thank You All.

 

thank god i found this thread..

helped me a lot..

 

Hi! Very useful guide thanks!
I hope you dont mind if I add a link in my Intel Guide.

 

Feel free to to do so!

Guide finally updated again today. Let me know if there are still missing and/or incorrect processor entries.

 

just asking, is there such thing as T8400 ? TIA
