Intel Mobile Processor Compatibility Guide

As I understand it now, your new CPU runs cooler than your old one. What's to worry? That is probably due to new paste, possibly better paste.

 

im using same thermal paste

 

Both are 65nm form, the T7250 is a Merom,
you'll see significant difference in temperature if you change to Penryn 45nm

 

is this thread open for nit picky remarks?
there would appear to be a T5670
also a whole lot of strange X and QX

 

Hi there guys,I am new to this wonderful forum and also a noob when it comes to CPUs.
So please go easy on me
I have this problem
I need to upgrade my toshibas' l555-10r P7450 CPU to a quad Q9100 mobile.
Is it possible? the socket appears to be the same (P478) and the chipset as well (GM45) .The FbS is 1066 on both cpus.
That is the info I have got so far. What else should i keep in mind about the compatibility.
I am sorry for the long post (really sorry)

 

the thing is that quads might not work... this is because they pull more power and your motherboard might not support it... also it might not be supported by BIOS so basically ur computer won't boot... u can try and u can get lucky but dual cores will work for sure...and the best dual core is T9900... Q9100 might not work so if u get it , make sure u can return it.

 

Thanx again sean.
What do you think about x9100? I ve heard the extreme dual core series may not be compatible even if you have the right socket and chipset.

 

X9100 might work... more likely to work than Q9100 but it will run hot ... and you can't overclock it... even if it has unlocked multipliers as ur notebook PLL will be locked etc... the T9900 has same stock speed as X9100 and runs cooler so its a better option.

 

Would a T5450 and a T9900 be compatible in the same laptop?

 

Possibly... what's the chipset or even the model of the laptop?

 

the laptop is a Toshiba Satellite P205 S8811

 

I think you have a 965-Series chipset, in which case you won't be able to use a T9900. T9500 will be the best you can do.

 

According to the detailed specs it's a Mobile Intel® GM965 Express Chipset.

 

Hello, I guess this is the right topic for this.
I'm planning to upgrade my cpu and I could use some knowledge and guidance.
The laptop in question is Toshiba Equium A200-1V0
Here's the specs
Toshiba

it has T2310 cpu and the new one would T7500
Here's the specs
T2310
T7500

Now the questions. T2310 runs at 533 fsb and t75 at 800,
chipset should be GM965 Express (not 100% sure)
so, does that fsb matter, the motherboard should support 800,
and as far as I know, I dont have to do anything to this?

Other thing that I worry, is the voltage.
t2310 has 1.2125 which is higher than t75 1.075 - 1.175
Should I do something about this?

and last but not least, the bios. I'm wondering if it will work?
I know that the a200 model has been released with a c2d, but a lot lighter one, T5450 which is almost the same as t75

Please let me know everything else that I should know before I buy the cpu and put it inplace.

 

If you've got a 965, the T7500 shouldn't an issue. If you want to be safe, T5450 is probably a better bet, but I don't really see any reason for the T7500 not to work.

 

Take a look at:
http://www.intel.com/assets/pdf/datasheet/316273.pdf page 12

It says that Mobile 965PM should support all CPUs with 800MHz FSB [with DDR2-5300(or 667MHz) RAM]. The rest of it is up to You and Your skills with Google.com ;-)

 

Yeh, I agree with you, that I would be safer with the T5450, but i'm tryin to get a sweet deal for that t75.

Can you tell me anything about the volts?
Any knowledge about that?
Btw, really nice topic commander!

yep, I did read that aswell
hmm... do I have to change my ram from 667mhz to 800mhz?
or will it work with the new cpu just fine?

 

your ram is fine, in fact if you buy 800mhz ram it will run at 667mhz with this chipset.

 

Hello all, I've been reading this thread for quite sometime and decided to upgrade my Toshiba Equium A200-1V0 (T2310 1.4Ghz, 2GB DDR2 533Mhz, 120GB Toshiba HDD).. I got a replacement T7500 for quite cheap and luckily it booted I also add a 2GB module-3GB total and replace the HDD with OCZ Solid 2 60GB..the laptop just doesn't feel the same..
Thank you CommanderWolf for creating the guide-otherwise I'd still be scratching my head for a compatible CPU lol..
so Toshiba A200-1V0 bios ver. 2.5--->T7500 upgrade success

Thisideup, I think you can proceed for T7500 too as we have the same lappy.

 

excellent, thank you for the info!

 

hi guys,

i have laptop Lenovo Support & downloads - Detailed specifications - ThinkPad R61e
with m550 celeron (socet p) procesor. chipset gm965
same as you i want to upgrade it with core 2duo processors, to make a normal working computer

a wanted to put t7500 inside but unfortunately, i have only few options:

processors t5500 and t7200 that was not mentioned in your list for successful upgrade. will they work in above mentioned notebook?

thnx

 

T5500 and T7200 are socket M processors and will not fit in yours. Get socket P Processor.

 

Hello, I have a Dell Latitude D520 with the Intel945GM/940GMLchipset and a Merom T5500 1.66 GHz processor I would like to upgrade. From the compatibility guide it looks like a T7600 2.33 GHz will work. Bus Speed, Watts, etc all match. The only spec that is different is the T7600 lists VT - my bios does not have a VT option. VT is not important to me on this notebook. Will the T7600 work as an upgrade to the T5500? Or am I limited to the T5750 2GHz?

I'm looking at the list provided here (which lists the T5500 and T7600 in the same group) and the following page at Intel.
http://ark.intel.com/ProductCollection.aspx?familyID=26548&MarketSegment=MBL

Thanks for any info, Scott

 

If your D520 can take a T5500, it probably has a 945 (rather than a 940) and can thus probably take any of the Socket M Core Duos and Core 2 Duos. That being said, the T7600 should work; if your BIOS doesn't support VT, you just won't be able to use VT.

 

Thanks for the fast reply! That is good news. Looking at the display properties it does show "Mobile Intel 945GM Express Chipset Family". I had gotten the "Intel945GM/940GML chipset" info from the Setup/Bios screen.

I have been looking for compatibility info all around in this forum and searching at Dell forums did not get me anything specific. The VT option was my only concern when I looked at the Intel chart but I do not need the VT capability in this notebook.

Now if I can just find a deal on ebay. I recently saw one go for $142 and typically you can "buy it now" for about $200.

I will post my results when I install the processor. I'm thinking the T7600 will be a good bump from the T5500 and swapping out the 5400 RPM drive with a 7200 RPM drive or SSD will breath some new life into the Dell Latitude D520.

Thanks for the great guide and information.

 

Hi all, first post here. What an excellent guide, appreciate the work involved.

I have an Advent 7201 (made by Quanta AL-096 PL5C). I believe it's a Intel 943GLM Express chipset with ATI Radeon Xpress graphics. The CPU is a Celeron M 440. I recently changed this for a T2250, which started and was recognised OK, but shut down the laptop after varying amounts of time. Windows would not load at all, laptop would shut down. I am starting to think the T2250 is faulty (very cheap from Ebay), or may be incompatible. What are your thoughts?

Name Intel Celeron M 440
Codename Yonah
Specification Intel(R) Celeron(R) M CPU 440 @ 1.86GHz
Package (platform ID) Socket 479 mPGA (0x5)
CPUID 6.E.C
Extended CPUID 6.E
Core Stepping D0
Technology 65 nm
Core Speed 1866.7 MHz
Multiplier x FSB 14.0 x 133.3 MHz
Rated Bus speed 533.4 MHz
Stock frequency 1866 MHz
Instructions sets MMX, SSE, SSE2, SSE3
L1 Data cache 32 KBytes, 8-way set associative, 64-byte line size
L1 Instruction cache 32 KBytes, 8-way set associative, 64-byte line size
L2 cache 1024 KBytes, 4-way set associative, 64-byte line size


What CPU's are compatible with my laptop? Thank you very much in advance.

 

They are both Yonah cores with a 533 buss, and both are socket M so the T2250 should be compatible. The first thing I would do is remount the heatsink making sure that you clean the surface with Isopropyl alcohol (do NOT use rubbing alcohol as it contains glycerine or some other form of lubrication that will act as an insulator causing the temps to be considerably higher). Next inspect the surface of the heatsink and the cpu to make sure there aren't any defects that could prevent them from mating properly. Than apply a fresh layer of TIM and made sure the heatsink is securely mounted and flush.

Some of the others could have some other ideas.

 

Thank you for replying PapaSmurf69. I am a PC tech, but less confident with laptops. I have become quite familiar with dissmantling my laptop and cleaned it all very thoroughly. I cleaned the CPU/GPU heatsink assembly of old compound using TIM cleaner, and re-applied fresh compound.

The T2250 I bought from Ebay was very very cheap, which is why I now believe it to be faulty. The lappy did power up, and the CPU was recognised corrently. And you just confirmed that the T2250 is compatible with my laptop. I just needed to be certain before I buy another T2250/T2350/T2450. Do you know what other CPU's would also be compatible?

Thanks for your time.

 

See the first page of this thread. It lists all of the cpus that would be compatible with that socket and chipset.

 

It may be your chipset, have you made sure that it's not 340GML?
This may help you identify the chipset:
http://forum.notebookreview.com/acer/206137-upgraded-acer-3680-celeron-cpu-t5300.html

 

Thank you ellalan. That made me question my sanity so re-checked the chipset. This is where the confusion kicks in. This is the spec page from the manufacturer UKT Support - Advent 7201 Laptop Where is states "Chipset - Mobile Intel 943GML Express". But when I check using CPU-z or PC Wizard there is no mention of an Intel chipset, but an ATI RS400/RC400/RC410.

I'm at a loss here. I don't understand why my lappy is different from the spec page. So it seems there is no Intel chipset in my laptop at all, can someone help me find a little info on what CPU's my ATI chipset will support.

Many thanks.

 

According to this, link. Chipset any socket M Core2. But remember there can be limitations that are not chipset. For example BIOS, MoBo.

Is it correct you are going from single core to dual core? If so that in the past has caused some issue.

I do not know your system so just throwing some thoughts out. I have no actual knowledge, sorry.

 

I have a toshiba satellite a55 s1063 with a celeron 370 dothan 1024 with the 855/852gm chipset what is the max proc It will suport

 

I'm pretty sure you should be able to use any 400MHz FSB Pentium M, right up through the 765. 745 or even 735 may be the best bang for your buck, though.

 

thanks for the really nice work!

 

but the 765 745 735 are 2 mb cache thats why I was confused I do know it has to be 400 MHz fsb but was onshore on the cache

 

OMG awesome guide! err...cept I couldn't find the answer to the question I needed the guide for T_T.
I am buying a computer: *DV8t* and want to upgrade to i7-860. I am going to be putting in thermal goop so why not? but I don't see compatibility/sockets listed for any of the i5s and only a couple i7. are all i7 socket 989? and where would i5 fit? could I upgrade from i7 720 to i7 860...or better yet i5 540 *wishful thinking* xD

EDIT: appears 720/540 are socket 988 as opposed to 989.

then the 860 is 1156

*head explodes*

 

ok so I upgraded to a 765 but now my system only reads it at 600mhz can someone help

 

Are you sure it's not just SpeedStepping? How are you reading the CPU speed, and what is it reading if you load up the computer (ie with Prime95)?

 

I used everest ultimate, CPU-z then I booted of live cd and all of them read the CPU at 600 MHz

one of toshibas laptop models with the same BIOS uses the 725 I also tried the 725 before the 765 and it read at 600 MHz also they were 600mhz with 2mb cache so the motherboard takes the cache but does not no the cpu so now I need to find a moded bios or something or Im out $150

 

Does it still say 600MHz when you load the machine?

I think you should've mentioned that the 725 didn't seem to be working properly... that's very much a red flag. I don't know what the issue could be... it could be a BIOS problem, or you might have an 85X chipset that isn't the 855, and those might actually not support anything other than Celerons...

 

@Ozlay

I'm am interested to how things work out for you, I have the same laptop. I would also like to upgrade, but have been unsure what will, and what won't work. So far I've read that I can only upgrade to 1GB of ram, and that hard drives over 120 GB have been problematic, but nothing about the cpu, that is untill now. Please keep us posted, as your experiences could be very informative for me. Thanks.

 

I can confirm that the a55-s1063 can only access up to a maximum of 1 gig of ram. While it is supposed to be ATA-6 (which means it does support drives larger than 137gb in size), there is some question as to whether all of the bios for that model do indeed have the 48bit addressing support at the bios level to properly support drives that large so anything larger than 120gigs is a crap shoot. If you do decide to go with a drive larger than 137gigs make sure that the first partition is 120gigs or smaller and create a second partition with the remaining space. Be sure to backup regularly though.

Also, if you do put in a drive larger than 137gigs use something like S.I.W. and look under Hardware - Storage Devices to see if it lists 48bit support or not.

 

The i7-860 is a _desktop_ processor, thus the 1156 LGA. All notebooks use either mobile processors (all of them will be identified with a M at the end (or rarely an E), like i7-720QM, or i5-540M) or the desktop i7-9XX series (for the Clevo D900F with it's monster LGA1366 socket).

For quick overviews of known notebook and desktop processors, Wikipedia provides a good list.

List of Intel Core i7 microprocessors - Wikipedia, the free encyclopedia
List of Intel Core i5 microprocessors - Wikipedia, the free encyclopedia
List of Intel Core i3 microprocessors - Wikipedia, the free encyclopedia

 

The BIOS does not show the clock freq well when the laptop boots up there is a Pentium m logo on the screen when I have the 725 or the 765 in it and when I have the stuck CPU in it has a Intel inside logo also one of Toshiba's other laptop the a55 s3261 uses the 725 and has the same BIOS so I don't understand why it will not take the 725 unless there are more then one 725 chip with a 2mb cache

also was thinking if I could upgrade to a better CPU that It may let me put more memory in then 1 gig I don't no how laptops work but when I upgraded my desktop CPU from 4600+ to 6000+ It added support for more memory and was twice the amount that the manufacturer said it would support

 

Very nice guide! Really helpful.

 

A brilliant piece of work and very valuable...
It answers lots of things for me whilst doing an upgrade here...

Thanks

I would like to report a succesfull processor upgrade of an Acer Aspire 5735z with a GL40 chipset from a T3200 to a T7800 C2D.

Before :


After :

 

just one question.... my laptop is acer 5562 with t2300 - thinking to upgrade to t7200, based on the list, it is compatible, but the thing is, how about the bios? i have downloaded the phoenix bios v1.28, will it be compatible? thanks in advanced, commander.

 

Yes, if there's already a dual core running you can just drop compatible C2D and it'll work even without a BIOS update but if you have updated, it wouldn't harm either.
