GL40 Chipset CPU compatibility?

First of all I would like to thank you for your lengthy reply.
I should have made it clearer, I already have a desktop with an i7-2600K / 8GB and that's where the real work gets done. This laptop is very useful though for when I'm in vacations or away from my "base" and I need to do some fast video editing, photoshop, even cubase and as it is now, it's not unbearable to work with, but if I could do a cpu upgrade that would be worth it (and be able to run a few games smoother) it would be great.

And since I do have a spare cpu around, I'm curious whether it's worth the fuss of taking two laptops apart (I'm quite good at it so that's no prob) in order to give a speed boost or I'll end up wasting a couple of hours over nothing.

 

Theoretically, a T8300 will work with a GL40 chipset and will be snappier than your current T4200. Just make sure you have the latest bios installed. You can put a T9300,T9500 or even an x9000 if you want. Though I suggest a T9300 for better value for your money.

 

I may be picking up a blue Toshiba Satellite L305-somethingorother with the GL40 chipset later today. It came with and has a T4200 Pentium dual-core and I'll probably pick up a T9300 for it. The only downside to this particular laptop is that it's running Vista Ultimate 32-bit So there won't be any sense in upgrading beyond 3GB of memory. I will definitely give it 3GB since it only has 2GB now. My Acer has been running Ubuntu 12.04 for awhile and it's great on the T4300 and never uses over 1700MB of so of memory so I'll cannibalize one of the 2GB chips to throw in the Toshiba and take one of the 1GB chips from it to put back in the Acer. Two GL40 laptops with 3GB of memory, one on Windows, one on Ubuntu, one for work, one for play. I like it.

 

First of all I would like to say THANK YOU to anybody who contributed to this thread as without their help me and many other people wouldn't be able to do anything with their old laptops.

I have just successfully upgraded my Acer Aspire 5735z from useless T3200 (65nm) to cooler, faster, less power consuming T4400 (45nm). Everything worked fine. I have also added 2gb of ram so now i have 4 in total and installed 64bit windows 7. There was a bit of problem with 4gb that was caused by the bios. I had version 1.08 on board, which was the latest for 5735z but it didn't allow me to use all 4 gigs - only 2.93 even in 64 bit windows. Fortunately i had found that bios 1.10 of Acer 5735 can be installed on 5735z to fix this problem and so i did. Now with "new" cpu, more ram, clean OS i feel like i bought new laptop but i've spent only 20 pounds.

 

UPDATE
I found a bargain buying T6670 for 7 pounds and I upgraded my laptop again today. Only thing than I can say is that is was totally worth it. Processor is running faster and I am getting even lower temperatures (which in my case are 40-45 degrees Celsius) and therefore it's even more quiet, to be honest for 90% of time when I'm browsing or watching youtube the fan runs noiseless.

My advise is: when you want to upgrade on GL40 chipset (or any compatible) get a 45nm processor!!!

 

Hi,

I've have acer travelmate 5330 with (socket P) Celeron M 575 on GL40 chipset ( 667 fsb).

I want to upgrade my cpu with a dual core processor ( T8300 ) or some other one.
Is that possible on this laptop or no ?
thank you

 

For ~$70 for the T8300 and up to 4GB DDR2 RAM I would say this is a reasonable upgrade (for ~3x the cpu performance and double? or quadruple? the RAM).

As mentioned; DDR 3 physically won't work (not to mention electrically too). But - it won't hurt if you can find the 'best' DDR2 SoDIMMs you can - it may make your system more responsive as I have recently found out for my varied setups.

See:
http://forum.notebookreview.com/har...m-full-speed-help-screenshots-appreciate.html



A few questions before you go ahead:
Are you comfortable and confident in taking apart and re-assembling your system properly?
Do you have an intended use for this upgraded system - or is this for fun/learning at this point?
Are you prepared to be without a system if things don't work out as you expect?
Would a new system (even refurbished/second-hand) be a better alternative?


I am not recommending for you to go ahead (I'll freely admit that I know nothing about upgrading cpu's in mobile systems) - but I'm hopefully showing you some of the potential pit-falls of this upgrade.

If you can put the much better cpu and 2GB or better yet: 4GB RAM for around $70 - I would definitely recommend this 'upgrade' wholeheartedly.

It would put you (processor-wise, not gpu, of course) at this 'current' level (and anything lower):

See:
Lenovo IdeaPad S405 59342926 w/ AMD A6-4455M, 4GB, 500GB, Radeon HD 7500, Win 8 at Memory Express

See PM 'score' 1319 for AMD A6 4455M:
PassMark - AMD A6-4455M APU - Price performance comparison

See PM 'score' 546 for your current cpu:
PassMark - PerformanceTest V7 CPU Benchmarks - List of Benchmarked CPUs

See PM 'score' 1491 for T8300 cpu:
PassMark - Intel Core2 Duo T8300 @ 2.40GHz - Price performance comparison



Good luck.

 

Which cpu do you recommend then?
And I planning to take 2 gb ddr2.

 

Quoting myself:

 

tilleroftheearth was suggesting that the T8300 would be a good CPU to upgrade to. Have you searched through this thread to see what other CPUs people have installed on this chipset? That would give you an idea of whether or not the T8300 would work, as well as what other options you might have. A little digging on my part shows that the T9300 is probably the fastest processor that will work in this machine, but I wouldn't pay much more for the T9300 over the T8300, since they're both 3-4 years old.

 

Hi All.
Just spent the best part of the morning reading through this thread, and being an avid upgrade fan / ebay addict, found it very useful and thought inspiring.
I recently swapped out my Celeron 900 processor for a T4500 in my next to useless and fairly annoying Cq56. What a transformation and when coupled with a Seagate Momentus Xt, it is my new best friend.
Now after reading this thread, I have the bug. With prices as they are on ebay with processors, for pocket money, I am going to buy a few different ones and note down what works and what doesn't, what a hobby!
With Windows 7 now starting in less than 20 seconds and hungry programs starting faster, Word 2007
In around 1 second, friends at work are showing an interest. (Lucrative little business idea!).
Thanks all, you have given me a new interest, and an excuse to retreat to the workshop whilst the wife watches rubbish on the telly.
Keep up the good work, I'm off to dismantle a Toshiba A200 to see if it will take a T7500 processor, if it does, ebay here I come as I have a few of these to do.
Thanks. Wizzo337.
(Got a T6600 somewhere in my processor mountain, I might try it in my Cq).

 

Thats because it is a 1066 mhz fsb chip. And would need further modding

 

Hi,
I hope this thread is still alive.
I want to upgrade a fujitsu-esprimo v6535 laptop - GL40 and i got stuck with an t7500 or t6500.
What is your recomandation?
Thank you in advance.

 

The T7500 is clocked faster, has twice the cache, and has Virtual Technology so I would go for that, especially if you intend to run any Virtual Machines on it. I tried a T6670 and a T7500 in my Toshiba with a GL40 chipset and I couldn't really tell the difference between them.

The T6500 is a newer 45nm cpu as opposed to the older T7500s 65nm architecture so the T6500 would probably provide slightly battery run time though so that might be a consideration.

 

I'm more interested in performance instead of battery life. Most of the time the laptop is plugged in. But I want to keep it cool. I already put a T3400 but the fan is struggling sometimes and the temperature reach 62 degrees.
Anyway, I read a few post behind that the T7500 will not work on GL40, and I want to be sure that if I buy it is gonna work.
Thank you for your answer.

 

The T7500 works quite well in a GL40 as that is what I am typing this post (and my previous post) on. A Toshiba L305-S5933. I went from the stock T3400 to the T7500. CPU temps are within 5C of each other. Here is a CPU_Z Validations of that laptop I just ran.

CPU-Z Validator 3.1

The one thing I noticed on my setup is that the ram (PC2-6400) is running at the same 667 that it did with the T3400, but I don't think it's related to the cpu or the chipset. I think it's the bios that Toshiba uses as it doesn't matter what CPU I put in it, the ram will run at 667. The FSB will run at the correct 800 (200 x 4), but the Memory won't.

Now all of that said, there could be bios issues that would prevent your specific laptop from correctly identifying the T7500 and allow it to work on your laptop, but the GL40 chipset would not cause that problem. Unfortunately, the only way to know for sure would be to try it unless you can find someone who has tried it on that same model.

 

Thanks for your prompt response.
I will order the T7500 and I'll let you guys know.

 

I installed the T7500 and it works perfect. The RAM still works at 666. Might be from the BIOS - It's possible to flash another BIOS than the one that the producer list it? - I;m just curios, i'm thinking that maybe i can unlock diffrent futures.
Thank you for your support.

 

Glad it worked out for you.

From what I've read it's quite common for a GL40 chipset based laptop to run the ram at 667 instead of 800. A bios update might change that (it didn't on my Toshiba), but I wouldn't worry about it too much. The performance difference is rather minimal and I doubt you would ever notice it. I definitely wouldn't go with a third party or hacked bios as the chances of borking the system entirely is simply too high. Try the latest bios from the laptop manufacturer and hope for the best.

 

Hello,

i have an Acer Aspire 7330 with GL40 and some years ago i upgraded to T7500. Next week i will get a T9500.

BUT my question is, had somebody succesfully installed 8GB memory in a GL40?

@amwjuju

The T8300 should be a better solution as the the T7500, because 65 nm (merom) -> 45 nm (penryn)
my T7500 is 60-70 C, so my fan is always running loud, while the 45 nm cpu´s are 30-40 C...

 

sooo, T9500 arrived and works perfect, with really cool temperatures!
8 GB PC6400 memory is now working, too! But only @667 instead @800... no options in bios to change timings...
is there a tool to change timings?

 

I have a Packard Bell EasyNote TJ65, with GL40 Chipset
Stock T4300, and today i upgrade to a T8300, and work like a charm

 

What is the real FSB rate of the GL40 chip? Intel shares opposing information on their site:

Here it says up to 667 mHz:
ARK | Compare Intel® Products

Here up to 800 mHz:
http://www.intel.com/content/dam/www/public/us/en/documents/datasheets/sm35-express-chipset-datasheet.pdf

I have a HP620 with T4500 proc. CPU-Z measured 800 mHz FSB, detected GL40, but reading the Chipset allows only 667 mHz, I thought my laptop has a GM45. So I ordered a P8800 processor. But I have just found that second link, where intel says it differently.

 

Hello guys,

After looking through this whole thread I have to say that I'm going to give T7700 CPU a try.
I have a question that is not related with CPUs but with RAM memory. It is mentioned that GL40 supports 8 GB of RAM. Is that true or not?
I have 3 GB of DDR3 1333 MHz (but works on 800 MHz normally) and I'm aiming for 8 GB for my Windows 7 x64 Professional.

 

hi guys, sry for diggin up this thread, but i need a bit of help..

So i got my hands on a Acer emachines e520 for around 50$, and that it brought a celeron 575 installed (single core 2.0) with all this talk about steam machines, i try'd the beta and can see my cpu being a bottleneck for decoding the stream (if its twitchy enough) so went around on ebay and got myself a t6670 for 8$. With all this said here comes the problem

after disassemble the damm thing (needs to be taken apart piece by piece, even display -.-) i changed cpu and assembled everything back together, unfortunally the laptop wont turn on anymore, and i mean completly dead, no lights no fan moving, i plug the cord and indicator lights wont turn on, Nothing, its like mobo isnt geting any juice, i then took it apart again (like 6 times allready xD) in hopes i 'd forgot something, but no, everything was as it should, (i have experience in building desktops).

when i tryd to power it on after the swap, i used only the batery wich is at 50% charge +/-, had used it last dawn, and i had the bios flashed allready to the latest one, now can some1 tell me what hapened?
They are both socket P, both use similar voltages, 31w vs 35w, gl40 chipset, the only diference is that one is single core garbage and the other one is a c2d less garbage lol, are they so diferent electrically that could short circuit the socket and blow something? prolly a diode? i find it hard to believe, since i've seen so many reports around the web that would work, and looking at their specs i dont se a reason not to...

in any case, if its something blown on the mobo, shouldnt the indicator light turn on when i plug the cord? arent they hardwired? meh im confused, someone wanna shed some light maybe? thanks

 

First off, unless you put the cpu in incorrectly, there is no chance that a GOOD and properly functioning T6670 would cause your problem and wouldn't damage the socket or the motherboard. A T9300 was shown to work in an E520 so there is no reason why a T6670 wouldn't The most likely problem is you have a short somewhere in the wiring or you made a mistake when you re-assembled the laptop. I know you stated that "everything was as it should", but you seriously need to double and triple check everything to make absolutely sure that you didn't miss anything or connected something incorrectly.

Next, try installing the original Celeron back in the laptop to see if it works with that cpu. If it does that tells you one of two things. Either you did indeed make a mistake when installing the T6670 that you corrected re-installing the original Celeron or the T6670 is defective. Since none of the lights are on at all I tend to believe it's the former.

If that doesn't work either then the most likely scenario is that you connected something wrong when you installed the T6670 that damaged the circuitry of the motherboard or the main power circuit.

 

i may have made a mistake somewhere but i hgihly doubt it, i allready took it apart and assembled it around 7 or 8 times now, i too believed it could be a short somewhere, that was my first instinct, so i disassemble it and it really looked like everything was as its suposed to be, theres not alot to go wrong in this chassis, the cables are pretty much "glued" to the chassis so when its time to assemble it they are easy to spot and cant go in the wrong "holes" due to distances.

Also i swap'd celeron again but no dice, still same issue, used AS5 (non conductive), and i know how to align a cpu in the socket lol, as i said in previous post im around desktops for quite a while, since overclock was made by junpers

I dont really care that much about teh laptop itself, but i like a challenge, and i'd love to figure out what went wrong and what can be done to fix it, and most important do it myself, its kind of a project, pc's are a hobby of mine.

It just dont make any sense, CPU should work on this board, even if it didnt it shouldnt short anything, just wouldnt boot, i dont think it'd prevent everything else to work even charging the batery.

Im on my launch break, but later after work im gona assemble it al together again, its in pieces atm, was planing in selling the parts, but i dont like the idea of giving up lol, i'll post results later

 

Have you taken precaution for ESD? that may be another reason for damaging your MB.

 

It still sounds like something in the charging/power system is either disconnected or shorted out otherwise there would be some lights on once you plug in the power brick.

 

i just put celeron back and assembled it, problems still persists.

Smurf, i realise that for a while now lol, im just trying to figure out what was teh cause for it.

ellalan, tbh i didnt, but i never care too much about it, while technically we should be doing it, i think thats very over rated, unless ur working in socks on a carpet and rubing the hardware xD

 

Unfortunately, it's next to impossible for any of us to diagnose that sort of problem without being right there looking at it.

Personally I believe that ESD is highly UNDER rated by most people. As far as I'm concerned (and I've been doing this since the mid 1960's on ham radio, audio, cameras, and now computer equipment) there would be a LOT fewer hardware failures if more people took the time to guard against it instead of just going at it willy nilly.

 

This is an important post for those on the GL40 chipset looking to upgrade their processors.

Firstly hello everyone, and I apologise for reviving an old thread (albeit has recent posts). I registered an account on this forum specifically to post this message. So without further ado, let me get straight into it.

If you're on the GL40 chipset and looking to upgrade your processor (provided you can open your laptop and replace the CPU), then you can upgrade your processor to any Socket P CPU that physically fits with a FSB of 800 MHz. As long as the CPU you desire to upgrade to is intended for Socket P, and has a FSB of 800MHz, the CPU will work! It does not matter if the CPU is not listed in your manufacturer manual's CPU support list, any of the below listed CPUs will work regardless.

I upgraded my laptop to an Intel Core 2 Duo T9300 which is not listed in my CPU support list. My manufacturer states the best my motherboard can take is a T6600. However the T9300 works perfectly, and is safe too (no overheating, no random reboots or any other issues)!

If you're on the GL40 chipset, you can upgrade to all of these processors listed below (however you must research into whether the TDP is acceptable by your motherboard):

Intel Core 2 Duo
T9500
T9300 (best value for performance, and compatible with most, if not all laptops on GL40 chipset)
T8300
T8100
T7800
T7700
T7500
T7300
T7250
T7100
T6970
T6900
T6670
T6600
T6570
T6500
T6400
T5900
T5870
T5800
T5670
T5470
T5270

Intel Pentium Dual-Core
T4500
T4400
T4300
T4200

Intel Celeron
925
900

This is an extensive list of CPUs supported on the GL40 chipset, and all of the above will work (provided you're in concordance with the TDP). If you find another processor not listed here which you desire to upgrade to, it will not work (unless you're willing to apply BESL/Pin mods). If you want to upgrade which is guaranteed to work, select a processor from the above list.

All the best.

 

can the GL40 take a quad core? i thought maybe i had read about people putting in quad cores on GL40?

 

Not without a custom BIOS and a pin mod, and even that might not work on all the machines with this chipset.

 

isn't the GL40 supposed to support ddr2 6400 (ddr2 800) ram?

 

You should be able to install and use DDR2-6400 without a problem.

 

mine down clocks to 667 even after bios update... guess it's an OEM thing.

 

Good evening guys!


I have E525, Intel Celeron 900 2.20Ghz single core.
