Intel Mobile Processor Compatibility Guide

I have a question that I've been searching around for an answer to and have been getting conflicting information from multiple people. This Toshiba Satellite A10-S2051 laptop I have just repaired has a 1.7 GHz Intel Celeron M 390 SINGLE core CPU that is just terrible. Now it's a socket 479 and I have a bunch of mobile processors laying around including a Intel Core 2 Duo T6400 that will fit in the socket of this motherboard. Now some people have said I could use it, other's have said I can't only upgrade using the Pentium M's. I would prefer to know for sure what my options are before closing this thing up all nice, neat, and tight only to find out it won't boot. Apparently the chipset in the motherboard is compatible up to 1066 so it says, but I don't think going any higher that 800 would even be smart. I am going to post the list given to me of processors that are compatible. Since these processors are older I'm looking for one that's just a duo core and cheap. The T6400 I think I paid $5 for including shipping. I don't want to put any money into this laptop, but if I can buy a CPU for $5 - $10 that will double maybe even triple the speed it would be worth it. Plus then I could put windows 64 bit on it. Which ever one of these is the newest, cheap, and anyone who knows a lot about the whole socket 479 478 etc issue would buy themselves. Thanks for the help anyone leaves and here is the list of CPU's I was given that are supposedly compatible and will work with a socket 479 motherboard out of a Toshiba Satellite A105-S2051

Intel Core 2 Duo T5550 Merom 1.83GHz, 2MB L2 Cache and 667MHz FSB
Intel Core 2 Duo T5670 Merom 1.8GHz, 2MB L2 Cache and 800MHz FSB
Intel Core 2 Duo T6400 Penryn 2GHz, 2MB L2 Cache and 800MHz FSB
Intel Core 2 Duo T7500 Merom 2.2GHz, 4MB L2 Cache and 800MHz HSB
Intel Core 2 Duo T8100 Penryn 2.1GHz, 3MB L2 Cache and 800MHz FSB
Intel Core 2 Duo T8300 Penryn 2.4GHz, 3MB L2 Cache and 800MHz FSB
Intel Core 2 Duo T9300 Penryn 2.5GHz, 6MB L2 Cache and 800MHz FSB

 

The 390 is a Dothan-based part, so I'd generally say you can't go further than Dothan Pentium Ms... however, it doesn't look like your laptop has an Intel chipset, so it's really hard to say anything for sure. I'd try to get like a low-end Yonah based dual core and just see if it works... they're super cheap now, and the worst that can happen is that it doesn't.

 

I just made an offer on eBay for $5.00 for a Toshiba Satellite A105-S4547 (motherboards look identical to mine) 47098870Q Intel CORE 2 DUO CPU Processor SL9JK . They are selling it for $6.99 so I offered 5, I'm sure they'll take it. Like you said they are cheap if you look. Here's the link to the CPU if you feel like checking. I think it will work. Toshiba Satellite A105 S4547 47098870Q Intel Core 2 Duo CPU Processor SL9JK | eBay

 

Hi Jason,

The sSpec SL9JK is the Intel Core Duo T2350 @ 1.87 GHz. This belongs to the generation of 'Intel Core' ('Enhanced Pentium M' microarchitecture) series of processors that were introduced before the 'Intel Core 2' series ('Core' microarchitecture).

I'm not sure how knowledgeable you are with processors, but make sure you don't get confused with the naming (damn Intel...);

For processors of the 'Yonah' codename, "Core" isn't the architecture. It's simply a line of processors under the 'Enhanced Pentium M' ('Pentium ME') architecture. So, your T2350 that you linked above is part of this specification.

For processors of the 'Merom' and 'Penryn' codename (both are successors to 'Yonah'), "Core" is the architecture, but Intel also used it as the family name for processors under these codenames, adding a "2" to signify second generation. So, for example, the T5900 ('Merom') and T9300 ('Penryn') are both under this specification.

Are they both dual-core? Yes. What's the difference? 'Pentium ME' dual-cores don't support the x86-64 instruction set (required to run 64-bit Windows and 64-bit programs, as well as to support more than 3.3 GB of RAM), whereas 'Core' dual-cores do.

Additionally, the 'Pentium ME' processors never have a front-side bus (FSB) frequency greater than 667 MHz with the later models. Here, 'Merom' processor FSB frequencies (under the 'Core' architecture) start with 667 MHz, and in 'Penryn,' they start at 800 MHz.

If I've confused you, please do say!

Dylan.

 

Yeah you've confused me quite a bit! LOL!! But it's 5:10 am and I'm just about to call it a night so I am in no shape to actually compute all that information you just gave me. HAHA! If you could, I would very much appreciate, tell me or give me a selection of any two core CPU that I can swap out the crapola Celeron M 390 for that's officially in that "it's old and cheap" area on eBay ya know. Like how they have duo core CPU's that are much newer than the socket M's for $5. I'm looking for something like that sir. I just don't want to order anything, tear it all down, put it back together and get a blank screen! LOL! It would be nice to just know for sure that the damn laptop is going to turn on and be a little quicker. It just runs so so so slow when trying to do any kind of multiple things on it. I mean if you open explorer while running defraggler it takes a few seconds to open all the way and be useable. That's with having 0 fragments on the hard drive and maxed out ram it's still that slow. I just don't want the person who buys it to have to deal with that lag when I could spend $5 to $8 on a CPU to make it just an internet browsing, home work doing laptop which is exactly what it's going to be fore. Thank you again very much for your help!!!

 

Like I said, I think you should try Yonah-based dual-cores like the T2060/2080.

 

That's very much understandable but there's no way to be certain of an actual list of compatible processors for the laptop as this list is stored in the computer BIOS as microcode which isn't human-friendly (it's just a series of alphanumeric characters that only Intel/AMD and computer manufacturers can work out). Toshiba might know, but I doubt they would tell you. I had the same trouble with ASUS and my laptop.

With that said, the best advise I can give you is after checking up the specification of the Satellite A105-S4547. First and foremost, CNET has a listing of the computer running with the Core Duo T2350 you linked to, so that should work, but let's see what other options the computer has:

In order to gather a list of processors that might work, there are certain parts of the specification that you should look at. Unfortunately, not all of the information is always provided (such as the motherboard thermal limit), but there's usually enough to make a decent assumption. These are:

Platform - Napa/Napa Refresh
RAM Types Supported - DDR2-533 (PC2-4200), DDR2-667 (PC2-5300) - up to 4 GB
Chipset - Intel 945G (Intel 945GM)
GPU - Intel GMA 950 - 256 MB, DirectX 9.0c, OpenGL 1.4 on Windows, OpenGL 2.1 on Linux
Processor Socket Socket M
Supported CPU Codenames - Yonah, Merom
Supported Bus (FSB) Frequencis - 553 MHz, 667 MHz
Maximum TDP (Thermal Limitation) - 34 W

And, now your list. For the best choices, I've provided more detail, since you'll probably want to just disregard the Celerons.

CPU @ core frequency (L2 cache (megabytes)/FSB frequency (megahertz)/maximum TDP (watts)

Intel Celeron M 410
Intel Celeron M 420
Intel Celeron M 430
Intel Celeron M 440
Intel Celeron M 450
Intel Celeron M 520
Intel Celeron M 530
Intel Core 2 Duo T5500 @ 1.67 GHz (2M/667/34)
Intel Core 2 Duo T5600 @ 1.83 GHz (2M/667/34)
Intel Core 2 Duo T5850 @ 2.00 GHz (2M/667/34)
Intel Core 2 Duo T7400 @ 2.17 GHz (4M/667/34)
Intel Core 2 Duo T7600 @ 2.33 GHz (4M/667/34)
Intel Core Duo T2050 @ 1.60 GHz (2M/533/31)
Intel Core Duo T2250 @ 1.73 GHz (2M/533/31)
Intel Core Duo T2300 @ 1.67 GHz (2M/667/31)
Intel Core Duo T2350 @ 1.87 GHz (2M/533/31)
Intel Core Duo T2400 @ 1.83 GHz (2M/667/31)
Intel Core Duo T2450 @ 2.00 GHz (2M/533/31)
Intel Core Duo T2500 @ 2.00 GHz (2M/667/31)
Intel Core Duo T2600 @ 2.17 GHz (2M/667/31)
Intel Core Duo T2700 @ 2.33 GHz (2M/667/31)
Intel Core Solo T1300
Intel Core Solo T1350
Intel Core Solo T1400

Out of those, I'd choose a Core 2 Duo (newer; better performance to power ratio) or Core Duo (still dual-core, so above the rest).

Good luck! :thumbsup:

 

Let me first thank you very much for such a detailed answer with a list and everything. That was perfect and very helpful. But, the problem with your answer sir is that the model laptop I am looking for an upgrade for is a Toshiba Satellite A105-S2051 with an Intel Celeron M 390 single core piece of , DDR2 2GB PC2 4200 553mhz, it has an ATI RC410 chipset ( I believe ). I'm sorry if you went to the link of the processor I had listed and just assumed it was that laptop model. I should have been much more specific and again apologize. I would just go ahead and pick from your list because the models are so close but I've had certain people tell me I could use any of the CPU's you've listed and others who have said I can't. So I don't want to jump to a conclusion before I know for sure. But maybe now that you know the exact model you can make another suggestion. Much appreciated.

 

Haha, no problem! Somebody, somewhere will find it useful. Let's be optimistic.

Okay, according to Toshiba, it's the AMD Radeon Xpress 200M (later renamed to Xpress 1150) chipset. "RC410" is the codename for it. The graphics chip is the AMD Radeon Xpress X200M, with up to 128 MB of video RAM, depending on the RAM inside the machine.

Unfortunately, this makes it a little difficult as I don't think AMD produces chipsets designed for Intel processors these days; as far as I know, all new AMD chipsets are for AMD processors only, but don't quote me on that.

In such a case, it's best to go with something from the same timeframe. So, as CW said, the Celeron 390 is from the Dothan codename. The only options that I think would be safe, are those under the Yonah codename, assuming that the FSB isn't at its limit, at 400 MHz. Just to make sure, stick with 400 and 533 MHz bus frequencies.

For processor models available for multiple CPU sockets, I've included the sSpec numbers for Socket M to make sure you order the correct one compatible with your socket.

Intel Celeron M 410 @ 1.47 GHz (1M/533/27)
Intel Celeron M 420 @ 1.60 GHz (1M/533/27)
Intel Celeron M 430 @ 1.73 GHz (1M/533/27)
Intel Celeron M 440 @ 1.87 GHz (1M/533/27 - SL9KW)
Intel Celeron M 450 @ 2.00 GHz (1M/533/27)
Intel Celeron M 520 @ 1.60 GHz (1M/533/30)
Intel Celeron M 530 @ 1.73 GHz (1M/533/30 - SL9UY/SLGFL/SLA2G/SLA6Y)
Intel Core Solo T1250 @ 1.73 GHz (2M/533/31)
Intel Core Solo T1350 @ 1.87 GHz (2M/533/31)
Intel Core Duo T2050 @ 1.60 GHz (2M/533/31)
Intel Core Duo T2250 @ 1.73 GHz (2M/533/31)
Intel Core Duo T2350 @ 1.87 GHz (2M/533/31)
Intel Pentium Dual-Core T2060 @ 1.60 GHz (1M/533/31)
Intel Pentium Dual-Core T2080 @ 1.73 GHz (1M/533/31)
Intel Pentium Dual-Core T2130 @ 1.87 GHz (1M/533/31)
Intel Pentium Dual-Core T2350 @ 1.87 GHz (2M/533/31)

In essence, I don't think the dual-cores will work, judging by the dated hardware; it's a complete gamble. If you can find one super cheap, try it out. Maybe even the Core Duo T2350 as we discussed earlier.

If you don't want to risk it, you can go with the Celeron M 530.

Hei..



So i think i got the idea about first 3 sockets on pic.. 479, socket M and Socket P.. but whats the last cpu/socket

When checking cpu-world for some cpu info i noticed BGA479 a lot.. QTDG (Intel Core 2 Duo T7600) SL9SJ (Intel Core 2 Duo T7600) and more.. but when i wanted to find info about that socket.. i didn't find anything usefull..

Also.. that first cpu/socket 479 confuses me also.. since i only count 478pin/pinholes there.. meanwhile on wikipedia page

Anyone could explain? tnx

 

The last one is just a generic physical socket that can fit all of the aforementioned CPUs. A lot of manufacturers use them, and it's the main reason why physical compatibility is NOT a good indicator of overall compatibility. You should NOT look at sockets; you should look at chipsets.

 

k, but for example QTDG (Intel Core 2 Duo T7600) SLGKH (Intel Core 2 Duo T9900) both cpu's listed as BGA479.. i mean they couldnt possibly be for the old 479socket which was before socket M.. So they are for that generic socket? or whats the deal with those ? 4'th cpu on first post image has those 479pins.. and it was not from 479 era,

 

Hi,

Both of those processors are available for both the BGA479 and PGA478 (socket P) sockets. Socket P is the newer of the three (if you include M as well).

Dylan

 

BGA ball grid array is without pins and soldered in. It doesn't use a socket unless a special adapter with pins is soldered onto the CPU first. PGA, pin grid array, has pins and fits into a socket.

 

People are just calling them the wrong things because Intel doesn't make it easy to differentiate between the lot. Just ignore all this gibberish and understand that T7500 is for 945, T9900 is for 45, and so and so forth, and you'll be fine.

The forth CPU is definitely a BGA to PGA job and may possibly only work in laptops with a specific chipset and the generic socket.

 

Hi friends, i have a sony vaio Vgn-Fs515e, and form my cpu-z i see :
Celeron M
Socket 479 mPGA
chipset i910GML..
I have read this topic, but i haven't understand if i can put another processor, for example T2500.

Thanks a lot

 

Possibly a Pentium M with 400MHz FSB, I believe. A Core 2 Duo T2500 will not work.

 

Officially 910GML only supports Celerons.

I dunno how well it's locked down, but even if it's not, you probably still couldn't use anything better than that 400MHz FSB Pentium M.

 

ok, can i try increase fsb?

 

Even if you can increase your FSB speed, I don't think it will help on the compatibility front...

 

ok,i have undesrtand that it's good if i don't touch anything and i buy a new nb

 

hello from Greece...first time i see a thread ,so important,6 years later......i dont know if here is the correct thread to write my upgrades, thanks to your help......i have already upgrade an Acer travelmate P2303LM ,model ZL1 from Intel® Celeron® M Processor 340 to Intel® Pentium® M Processor 735,also a Toshiba satelitte M40-295 (PSM44E) works fine with the same processor,socket M both laptops.....i am waiting an Intel® Pentium® M Processor 755 for Toshiba.......acer works fine with OS Windows XP and Toshiba works fine with OS Linux 13.......i also have a Fujitsu Siemens amilo li2727model LV1,chipset GL960 with processor Intel® Pentium® Processor T2310 and ordered for this- Intel Core2 Duo T5850 2.16GHZ 2M 667 from e-bay socket P........thanks for everything i will write again after the upgrades,but i am almost sure that everything works fine thanks to you!
PS.please excuse my English
PS2.intel hasnot the specifications from Intel Core2 Duo T5850 2.16GHZ 2M 667 like never was....

 

like i said ,arrived today Intel Core2 Duo T5850 2.16GHZ 2M 667.....it takes 10 minutes to change the processor......everything work excellent....works fine without any problems!!!!! i will write again when arrived the other processor for Toshiba!!!!

 

Indeed, Intel doesn't list every processor on its site. For example, my original T5900 isn't on there either.

I'm glad the upgrade was successful.

Hi guys,

I've an TOSHIBA Satellite P300 26L, with type : Intel® Centrino® 2 Processor Technology featuring Intel® Core™2 Duo processor P8700, Intel® GM45 Express chipset and Intel® WiFi

more info http://www.toshiba.eu/discontinued-products/satellite-p300-26l/

I want to upgrade CPU with an T9900 or P9700.


are they both compatible with my laptop?

or others


P9700 = 478-pin micro-FCPGA
T9900 = 479-ball micro-FCBGA
X9100 = 478-pin micro-FCPGA
Q9100 = 478-pin micro-FCPGA
QX9300 = 478-pin micro-FCPGA

INFO FOR MY LAPTOP :

Ram : 8 gb ddr2 Corsair 800mhz
SSD : Samsung EVO 840 250GB
HDD : WD 750 GB 7200 Rpm Black
GPU : ATI Radeon 4650 HD
COOLING: ZALMAN - ZM-NC300U



Which model should I replace the CPU?

thanks...

 

T99 and P97 should both work; I wouldn't hold my breath for any of the Xs or Qs though.

 

Thank you for your interest.

Which processor should I choose you?

X and Q series in the following list, but may not work, you say or you're not sure?

CPU-Upgrade: Intel GM45 Express chipset processor support

More detailed information is laptop required for you?

thanks.

 

You should get the P97 or the T99... they are pretty much as close as you can get to guaranteed to work. The Xs and Qs usually will not work with laptops that did not ship with them.

 

Thank you again for info.

P, T series, which runs more stable with my laptop?

To me, the P series according to you?

----------------------------------------------------------------------

I have one more laptop:

TOSHIBA Satelite A300 17N

chipset : GL960



Laptop very slow, very difficult 720p watched on YouTube.
Which processor do you suggest?
Can I use the P8700?

 

Personally, I'd get something like a T9600, but between the T99 and P97 it really just depends if you want a little more power or a little less heat... for everything except the most CPU intensive tasks, they are going to be practically the same.

The GL960 doesn't officially support anything better than that Pentium dual core. Sometimes 800MHz FSB Socket P Merom/Penryn will work, but there's no guarantee, ever. The P8700 and all other 1066MHz FSB Socket P chips will not work, for sure.

If you want to try upgrading it try like a T7500 or T8300, so you aren't out too much if it doesn't work.

Hi Commander Wolf,

I upgrade CPU from a T2370 to a T7500

and from P8700 to a P9700

2 laptops is working to faster and no problems, bugs.. Thanks for the help.

 

Hey I don't know if you tell it to someone but i wanna know if i can upgrade the cpu of my asus X51RL based on a c2d T5250. socket P if i can upgrade to a T9900 or Q9100 (but if i have understand i already have to get a tipical motherboard or bios for the last one).

Thanks for your subject it's give me hope for this old notebook.

 

Hello,

The T5250 is a Merom chip, so I'd say you might want to try the T7xxx range. If you really want to try a Penryn chip, then I'd suggest buying a very cheap Celeron 900 or 925 to test for Penryn support, before going all out on a T9xxx model.

Personally, I went from a Celeron M 575 to a Core2 Duo T5900, and from there, I purchased a Celeron 925 from eBay (it was £5) to test for Penryn support, and after the Celeron worked, I could then get the best chip in terms of price to performance, the T9300 (that was £45).

I would say don't go for anything in the T9xxx range except the T9300 or T9500 because the rest use different FSB frequencies and will therefore be slowed down to allow your chipset to manage with them (thus rendering any performance benefits, useless).

I went for the T9300 because the T9500 was almost double the price, and only offers a 100 MHz increase in core frequency over the T9300 - not worth it.

And it's almost a certainty that any Core2 Quad or Core2 Extreme will NOT work in a GL960 machine (including hybrids like GML960 and GME965).

 

What's the best CPU for Asus VX2S laptop?
It's 965 chpset.

 

Axel F, you can upgrade to T9500 or X9000. With mods, if they are applicable, probably even T9900/X9100.

 

For the GM965 chipset, you should stick with models with a front-side bus frequency of 800 MT/s ( Santa Rosa and Santa Rosa Refresh). Anything beyond that ( Montevina) may still work because of the similar microcode, but be aware that the frequencies Intel intended will not be what you'll experience. This is because the chipset will slow the front-side bus frequency down from 1066 MT/s to 800 MT/s, which will result in the processor frequency itself slowing down. That's why I would suggest you stick with Santa Rosa Refresh parts (T6xxx/T8xxx/T9xxx/Q9xxx/X9xxx).

Intel Core2 Duo T9300
Intel Core2 Duo T9500
Intel Core2 Extreme X9000
Intel Core2 Quad Q9000

The models in bold are the best options, but are unlikely to work unless your machine has sufficient cooling for them. Additionally, support for them is more specialized by the vendors of each laptop, so I wouldn't expect them to be supported in a standard notebook (15-16").

If you can get the T9500 cheap enough, go for it. Otherwise, the T9300 is the best option, price-to-performance-wise.

 

A Q9000 will not work, and it being 1066Mhz FSB and requiring greater cooling is the least of the problems. Very few laptops came with the ability to use them. It also seems that some laptops are capable to be modded to use one.

Also, without some simple mods to the motherboard, running any Core 2 (besides the extremes and celerons) at an FSB that isn't the default one will force it into its lowest multiplier.

 

You should perhaps reword that to a frequency that the chipset doesn't support.

- GL960 supports 533 MT/s
- GLE960, GME960, GM965, GME965 and PM965 support 533/667/800 MT/s

 

No, I don't think you understand me. If the processor supports, say 800Mhz FSB and you boot it at 1066Mhz FSB, it will be stuck on a 6x multiplier. Any FSB speed that isn't the one specified for that processor will force the processor to work at its lowest multiplier, which is 6x. This doesn't apply to Celerons (since they don't have any other available multiplier) or Extreme processors (since you can just change the multiplier at will). You can get around this "feature" but it requires a quick mod to the motherboard.

 

Thanks for your comment, it's realy cool to see that, i'll test next month, but today i have to see if the motherboard of my X550CC is dead or not, i hope it's alive and maybe one day upgrade my I5 to an I7 ^^ have a good day guy

peace

 

I do understand, buddy. I think I mentioned that. It's all good.

No worries, be sure to let us know how the test goes!

 

hi all

i have a toshiba satellite m100 laptop
with i945gm chipset wich run on intel core2duo t5200 1.6ghz 533fsb l2 2mb cache

i want to try upgrade my laptop cpu
afaik if i wenna upgrade it i have to match the socket, fsm and bios

but so far i cant find any great 533fsb cpu so
- can i put same socket but higher fsb for my laptop ? if i can i try to put Core 2 Duo T7600 2333 4096 667
cause this is best for this socket
-how i can determine my laptop is support for t7600 cpu or i need to update bios ??

thanks in advance

 

lengkapgan, I googled it will accept T7600. You'd better update BIOS prior to upgrading in any scenario.

 

well that's good that my bios can handle it
but does it worth to upgrade as fsb doesnt match ?

 

lengkapgan, your motherboard supports 667MHz FSB as well as 533MHz, so there is no problem.
