Upgraded Acer 3680 Celeron CPU to a T5300!

Oh yeah. No doubt. the 7k200 is awesome!

 

If you'll look back a number of pages, I already did this.
I can't 100% confirm I have the 940 chipset but I think I do.
Model 3680-2574 manufactured in 2006

T2250 Core Duo: No worky
T1350 Core Solo: Worky

Benefits: extra hour of battery life, extra 1MB L2 cache, quicker response, cooler running with speedstep

Now all I need as a 7200 RPM HD.

 

I am following this thread. I am able to upgrade my Acer 3680-2472 from M520 to T5200. I got the CPU from ebay ~$63 shipped.

Acer 3680-2472,
Model ZR1
The motherboard code is MB.AZL06.003.
Intel i943GML chipset

With Celeron M520 cpu,
Vista Performance Index - Processor Subscore = 3.8

With T5200 cpu,
Vista Performance Index - Processor Subscore = 4.7

 

Mine didnt go up that much (performance anxiety?) but it did go up a few marks... Congrats on the upgrade!!!

 

Hey guys, ive read the thread from back to front, took my laptop apart fully, and tried the t5200 core 2 duo, but i get a black screen when boot up although the celero works if replaced. i have the bios upgraded from page 1, and the model is aspire 3682 WXMi (3680) heres the wizard results...

Motherboard: Acer INC Prespar1
Chipset: Intel i943/940GML
CPU: Celeron M 420 @ 1600Mhz
Graphics: Intel 945GML Graphics
etc....

how am i geting a black screen???? other people with same specs have done it???? please help, i have the chip just sitting here??? would the latest bios work the one above the first page one?? as of 06/03/08??? help...

 

You probably have the i940. Try to check this:
http://forum.notebookreview.com/showpost.php?p=3108806&postcount=369

 

so glad the sticker on the memory slot has got some use

and it does make it easier to check which mobo you have.

so many laptops with same model number but with different internal make-up.
its enough to drive you mad

 

i gave you the results of the wizard utility, it states i943 and 940gm... look above at my post... i opened the casing again, but where do i check the version?? which memory sticker hoggie????

so this core 2 duo is useless to me???

 

Yes Hoggie your discover of the meaning of the label on the ram slot was a real columbus egg

Vistar, you should open the bigger cover under the laptop (then one where you find the slots of ram) and check the sticker marked in orange in this photo:

 

aahhh!!!! it is a 940....

after buyin the damn duo chip.... blast...

guess its goin back on ebay... lol

can i not upgrade to board... lol

 

I just placed a bid on a motherboard with duo capabilities... hope i win it let you guys know...

 

Updated the Front Page. Still Working on collecting all the People who have upgraded and to which CPUs.

Hoggie Take a look.

 

Perfect Krazy

and thanks for the mention

this thread is by far the best CPU upgrade thread on the net by a long way and its all thanks to you mate. Well Done
:wink:

 

@let me alone

Take alook at this:
Part / Model Number: MBAZL06001
Brand: ACER
Description: Refurbished Mb.azl06.001 Main Bd.sata.943gml.uma.w/rdr
Warranty: 30 Day Warranty

Are you sure that MBAZL06001 always have i940gml??

The sticker on my mobo said:
MBA ZL 06001 7070 E8C3 2505

The sticker on my mobo said:
MBA ZL 06001 7070 E8C3 2505

Can u advise the chipset in my laptop?

 

we have spotted a worrying trend with acer mobo's the spec seems to change with the mobo's but the model number of the laptops could be the same. its taken some hard research to find and spot all the changes.
in some cases it could have the same model number but the date of manufacture also plays a part in what chipset the unit contains.

99% sure but until you open the unit and take a look who knows.
but will take a look for you

 

all i can find for that model board is 940gml
sorry mate

 

Well, i never wrote to be sure that a MBAZL0600x board has the i940. According to what claims Acerparts and i reported here:

http://forum.notebookreview.com/showpost.php?p=3109541&postcount=373

the MBA ZL 06001 has the i943.

Ah, i see now what happened, you saw the message where Wac quoted my post before i corrected it. Sorry

 

@hoggie

Thanks Mate...so mind is 940gml

@letmealone
Do you think my Mobo (MBA ZL 06001 7070 E8C3 2505) has i 940gml? or i943gml?

thankssss

 

@n4r4k i think it has i943. Mine is MBAZL06003 and a T5200 works perfectly in it.
According to Acerparts, the boards with i940 have code MBTEB0600x

 

@Letmealone
Thanks for convincing me but finally I just successfully dissemble my laptop.
I did it bcoz I want to make sure the chipset I have.

After I took out the fan&cooler, I begin to observe the chipset.
The chipset is covered by the black plastic film.
I pull off the plastic film carefully, and I found nothing on the chipset's surface.
I MEAN THERE IS NOTHING WRITTEN THERE/ NO INFORMATION ABOUT THE CHIPSET!!!

There should be something there right? How come there is no text at all??
I guess the only way to proof is by changing the processor into T5200/T5300 and find out whether it works or not.

Any comment on this??
The reason why I did this is because I live in Indonesia, so if I buy the wrong processor, it would be difficult for me to sell it again.
Not the same case with you guys, where Ebay is there..
So I must be extra careful

Maybe the safest choice will be T1350?
Comment please.....

 

Yeah go for the T1350 just to be safe and could you tell me your Acer Aspire number?

PS: Hoggie could you please give me the link or information to the Chipset Identification. That way I can make a list.

 

@krazyphire

My ACER ASPIRE NUMBER:
ASPIRE 3683NWXCi
P/N: LX.AZK0C.005
MODEL NO: ZR1
SN : LXAZK0C0057070E8C32505

Any idea krazyphire?
BTW on the sticker located on palm rest (on the right side of touch pad) is written:

Aspire 3683NWXCi
Intel Celeron M430
14.1 WXGA crystalbrite LCD
MObile Intel 940GML Express Chipset

What do you think?
I guess I'm the only one from Asia, having unique Aspire Number than any of guys here...

 

Yeah the 3683 isn't a model that I've heard of...Hmmm. If it had a higher part number I was thinking it would have at least a i943, but I could be very wrong. Lets get someone who has a 940GML confirmed to give us their mobo code on the ram slot.

 

Hoggie, you're a hero for figuring it out. I took apart my 3680-2682 again, and was finally able to confirm that my MBAZL06003 is a 943GML. I had to wipe off a layer of grease and shine a flashlight on it to read the low contrast markings (it's dark grey on black!).

 

Thanks for selling me your 1.833GHz T5600. My 3680-2682 powered up with no problems, and booted up the first time! Apparently my MB also supports 667MHz FSB. PC Wizard seems to confim it.

Peak CPU temps are about the same as with the T5300, even though the T5600 die is much larger than the T5300. In fact, the T5600 die is about twice the size of the Celeron M 440!

My Vista CPU performance index score stayed at 4.8 (same as with the T5300), but the Graphics score jumped from 2.3 to 3.0, and the RAM score nudged up from 4.4 to 4.5.

Overall performance seems a little snappier, but not nearly as big a difference as going from the Celeron M to the T5300.

 

Glad someone could benifit from my mistake (buying socket M processors for my socket P laptops). I thought your setup supported the 667FSB, glad to be correct for a change.

I'm waiting for a T5450 socket P to arrive any day now. Maybe this time i can have the same good luck WAC has had. I did get my Bluetooth Dongle installed internally using a cheap 4 port hub i took out of it's case, so now my laptop has bluetooth.

Congrats on your bump in preformance WAC.


later, bigozone

 

FINALLYYY! My Chipset is i943 GML Calligosta yeahh.

Just open my laptop again.
Thank WAC, for inspiring me. Last time I did not observe the die.
Yes it's written on the die I943gml

Thanks krazyphire & Letmealone

So it's confirmed once again that Mobo with code :
MBA ZL 06001 and MBA ZL 06003 have i943 GML !!

So guys..what processor should I upgrade to?
From this forum I found out that the options for I943GML are:
1. T5200
2. T5300
3. T5600
4. T2050
5. T2080

Anyone know any seller in Ebay who are willing to ship to my Country, Indonesia??
Or Anyone here wants to sell/ help me..please let me know.

The Hunt for the C2D begins.....

 

Haha, If you'd told me your code I would have told you that mine has the MBAZL06001 . I say shoot for the top and go with a T5600.

 

The success of wac, making work a @667 T5600 processor on the i943, opens new perspectives in updating the 3680, and also gives a little to think about. Officially, Intel claims that this chipset is for supporting Celeron M processors @533: http://www.intel.com/products/chipsets/943gml/index.htm but for sure many laptops were directly sold with this chipset and low end dual core cpus running @533 fsb, mostly Pentium Dual Core. Now it is confirmed that it can also run @667, so that i cant now see a real difference from the i945. So what we can think about this ? My hypothesis is that i943 are second choice i945, not certified to run @667 but most do. A bit as second choice processors built to work at 2 Ghz and conservatively sold as 1.8 Ghz because not certified to be 100% stable at the original frequency... but most of them still working without problems if unlocked and "overclocked" @ 2.0 Ghz. So, making run a i943 @667 could be a bit as overclocking it. It could be interesting now seeing if wac was lucky or if all the i943 can go at that frequency. At n4r4k, who wants to be 100% sure of the success of his upgrade, i still suggest the T5300 as best choice. Obviously this is just my opinion, i would be glad to hear other points of view.

 

here's the intel link which i started to use but soon found out its not the best.

http://compare.intel.com/pcc/default.aspx?familyID=7&culture=en-US

but i also used wiki

anything else ?
another good link for you Krazy
http://en.wikipedia.org/wiki/List_of_Intel_chipsets

this thread just seems to get better.

could we knock up a list of spare chips going around lads.
we have been at this now for three months. and we could sell parts within the forum

 

I have an Asus A6rp. Here are the specifications.

Intel Celeron M 440 1.86Ghz 533FSB
ATI Radeon Express 200m Chipset
2 gig of ram
80 gb of HD
ATI Radeon Express 200m Video 256MB.

I am wondering if it is possible to upgrade the processor to a core duo or core 2 duo. Any adivice is appreciated.

TNX a lot.. please email me.. [email protected]

thank you very much... GodBless,,,

 

never fear the hog is here

so far found a handy chart for you.
http://users.erols.com/chare/chipsets.htm

still working on it for you

 

take a look at this and let me know what you think

http://users.erols.com/chare/chipsets.htm

 

here we go. we have a place to start from here on this web page.
not to clued up on asus chipsets but willing to learn lol

http://www.xbitlabs.com/articles/mobile/display/asus-a6r_6.html

we may have hit the jackpot mate a T2050 may slot straight in..but can you run PC wizard for me.
theres a link on the first post of this thread supplied by Krazy.run and post it here thanks
good luck.......The Hog......

 

we are now helping the asus owners lmao

 

I saw that same X-bit labs link thru google and I think that may be the best option. Go with Hoggie's suggestion of a T2050.

EDIT: Hoggie to the link you posted about the chipsets...I may be wrong, but those aren't mobile chipsets. lol

 

I feel very fortunate that the T5600 worked on the 943GML.

I downloaded the datasheet for the 945/943/940GML chip, and the only concrete statement I got from the document was that the 943GML is limited to 533 MHz (533 MHz PC2-4200 or 667 MHz PC2-5300 are allowed, but both run at 533 since PC2-5300 can run at either speed) for SDRAM only (pages 28, 109 & 164).

As for the FSB, page 27 says the 945GMS supports 533 and 667 FSB. Page 28 says the 940GML only supports 533 FSB, but the section for the 943GML doesn't say anything about the FSB. It's not clear if the 943GML should have the same FSB restriction, but if so, that would normally be explicitly called out in such a datasheet like it did for the 940GML. Also read the subsections for processor support - the 940GML is explicitly restricted to Celeron M only, while the 945GMS supports Core 2 Duo, Core Duo, Core Solo, and Celeron M. No mention of processor support for 943GML, but since we know that C2Ds work...

I agree that the 943s are very likely 2nd choice 945s, where they use the same die but fuse out certain gates to disable features for the lower grade part. It's possible that they didn't fuse out the 667 FSB ID, or it was never meant to be disabled, or they simply forgot to do it in the production test program. To add weight (or confusion) to this, PC-Wizard reports that my SDRAM is 533 MHz, even though I have 667 MHz PC2-5300 modules installed. This would imply that 667 SDRAM speed has been disabled with the appropriate ID(s) fused.

 

tnx a lot krazy and hoggie!!! i go for T2050...

 

hahaha... this chart is not for mobile chipset.. hehehe... peace.. can you give me a chart for mobile chipset??

 

ok wiki have a good chart for you to look at and is a good read for asus owners with the ati chipset.

the full mobile list can be found here.

intel first.

any more lists needed

 

Hoggie... is the core 2 duo T5500 fit to my lappy (a6rp)...?? because someone selling his T5500 to me.. ... help me pls.. thx a lot..

 

The Celeron in your system is a low power Yonah Core CPU. The T5500 is a Merom Core CPU, has a higher FSB (667), and a higher power output. The 940GML can't handle those specs.

 

your chipset can only handle 533fsb so the T5500 will not work.if it did i'l eat my aspire


the keyboard tastes nice

 

For anyone curious about undervolting their new Core 2 CPU I supplied some pics of my RM utility settings with idle temps. Using this program: http://cpu.rightmark.org/download/rmclock_235_bin.exe your computer should run a lot cooler and increase battery life by at least 15 minutes.

<--temps/CPU clock 800Mhz
<--management settings
<--Recommended Index and volt setting. Keep computer on "Performance on Demand" for optimal power saving.

 

Walmart Canada is selling Acer 5315-2803. Could this be upgraded to T5300??

 

nope... i have a 5315 and bought a T5300 before i understood that there are basically 2 different 479 pin mobile sockets... the T5300 is a socket M processor while the Arcadia MB in the Aspire 5315 is a Socket P based MB.

the following CPUs should fit the MB and work fine,
T5250, T5450, T7100, T7300... i have a T5450 in the mail now, and as soon as it arrives i'll post results and a few pics in the following threads:

KRAZY AND HOGGIE!! I SUCCESFULLY UPGRADE MY CELERON M TO CORE 2 DUO T5500 1.66GHZ 667 FSB..!! WITH NO PROBLEM.. SMOOTH!! HAHAHAHHA.... I LOVE ASUS MOTHERBOARDS... SOLID...!! IT CAN HANDLES 667FSB!!

Here's the evidence... hehehehe!!

 

All I can say is Wow. . You proved us wrong and for that I take my hat off to you Jecho. Congratz on your new Core 2 Duo.
