Upgraded Acer 3680 Celeron CPU to a T5300!

Hello

I have readed my chipset also wth everest 4,60 and it thels me i have a North Bridge : Mobile Intel Callistoga-G i943GML girlfriend of mine have the same laptop a aspire 3690 and evrest 4,60 thels here that she have the 940/943 the only difference in the 2 notebooks is that she have a M420 and i have a M440, and whe have diferent video chipset one my machiene there is the intel gml950 and my girl friend have a ati.
So i'm the luky one
Have also the same moaderboard as some one fiewe pages back i think he had a travelmate 42?? the sticker on the memory bay is MBAY702002xxxxxxx
Planing to uprade to a T7x00

Regards Edwin

 

Hi all,

Firstly, a BIG thank you to Krazy, Hoggie and the rest of you who have pioneered this upgrade and put it up here for all to read and benefit from.

I finally got to the last page, and during the read I successfully upgraded my 3680 (940gml) from a 1.6 M420 to a 1.86 T1350. Slightly annoyed that I couldn't stick in a C2D but I do have longer battery life and it is slightly faster under heavy CPU loads. Did some overclocking but any decent gain in performance means I also get 80C+ temps (I didn't bother cleaning the fan as was in a rush to feel the Core Solo power), so its coming apart again sometime soon for a spring cleaning and some AS5.

I can't remember if I read about a successful install of anything higher than a T1350 on the 940 chipset, but if there are any success stories or any rumors please let me know. I think I'm gonna try and find a T5300 and see if it won't work with a little fiddling. Wish me luck.

 

No Problem and Good Luck!

 

Please some help on blue screen (vista)
Have made the upgrade from a M440 to a T7600.
Is there a way to fix vista, ore do i have to reinstall?
Laptop runs fine in save mode, so maybe there is somthing i can change to run vista witout a reinstall.
Thanks

 

If you have a free partition, try installing Vista to that partition. Or run the windows recovery console on the Vista install disc.

 

I think i will need a vista dvd, have try the d2d buth no luck.
Seems there is sommething with a driver and the facktory image can noth solve this.
The instal from d2d crashes also afther first boot :S

 

Yo i found a way to mod you Intel 950 gma, software wise. I made it into the gma 965 that has hardware shading and software shading and also increases the ram from 64mb to 256mb

 

Do share.

 

I have this in my laptop.

MB.AZL06.... If it starts with that it is a 943GML

But Model of laptop is a Acer Aspire 3680-257? can't make out last number
looks like a 6. This was purchase at Walmart in Canada.

I Wish to upgrade to Duo. can I or maybe not cause of the 257? model ?

Thanks Paul

 

Yes you can, as long as the mem sticker says MB.AZL06 then you are alright with C2D.

The mem sticker says what mobo/chipset is in the laptop.

The 3680-2576 is the production code, like where and when it was made. I have 3682-NWXMi which is the asia region code.

Good luck with the upgrade and post the results.

 

Just to let you now that my upgarde 3690 to T7600 is okay.
Next upgrade a M103 DVB-T card waiting fore a connector to fit in the backsite off the 3690 And i'm looking fore a logitech 1,3Mp orbicam (module)
Thanks fore all the info who i found on this tread..

 

Another successful upgrade! I ended up with a T5600 ES (QTBS i think) unknowing what that was at first. Don't know if multiplier is unlocked as my bios won't let me touch it anyway. Booted right up and seems to work fine.
Doing movie conversions to ipod format(down to 500mb): the old Celeron 440 took about 115 minutes for a 126 minute movie. The C2D T5600 ES did the same movie in 52 minutes!! In general; seems to boot faster. Programs seem to load a bit faster as well. That's what I've noticed so far. Seems to run as cool to a bit cooler than the celeron did. In normal use, the fan rarely comes on. Under load, the air temp blown seems just a bit less than the celeron.
Any suggestions on how to crank this chip up a little?
Thanks for all the info. I used an article with pics on dissasembling an acer aspire. It helped a lot. Also laid all screws out in map form as I removed them. It went well, but I took it slow. I could do it much faster if I were to do it again. Scarry, but definately doable. Thanks Again!!
Oh; I currently have 1.5 gig ram (533). I ordered a matched set of 1gb-ers at 667 not realizing that they will probably just run at 533 anyway (oh well, they were only $16 total at newegg). I also recently added a 500gb HD at 5400rpm. partitioned off 350gb just for my movie collection! I have a movie list in exel format that is hyperlinked to the individual movies. Just click the name and the movie loads! Movies on demand!!

 

Great Thanks. I have a cpu ordered.

Paul

 

I think Intel recently removed the multiplier unlocked thingo on the ES chips, or so I read a while back.

I pretty sure the stock BIOS wouldn't let you fiddle with the multipliers anyways, its a very basic one. Have you tried RMClock or other similar software to see if the multiplier is unlocked?

As for overclocking it, Andy mentioned some ways and a program somewhere in this thread but I can't find it atm. There are a good couple programs out there (i'll try and give you a list later on) and if you want it to run even cooler you could try undervolting it with RMClock.

Andy also mentioned how he got his RAM running at 667mhz so that order might not be so bad after all.

I gotta run to rugby training but after that i'll see if I post links to all those pages I've mentioned, sorry for the rush.

 

Thanks for the info.
I have been using "CoreTemp" to check temps while converting movies. It's variable, but; max temp readings on core#0 is 71 and core#1 is 75. this is with a variable cpu load of up 90-something%. That's actually getting up there, isn't it?
Now, while just doing web stuff, core#0 is 46 and core#1 is 49. I did just get done converting two movies.
I did read where it mentioned undervolting and overclocking simultaneously.
I'll check out RMClock.
Thanks again.

 

Did you use Arctic Silver 5 on the new cpu? Those temps seem a little high. Also, did you clean out the fan when you had the laptop open?

CPUCool is the program Andy used to up the FSB from 533 to 667. And here is the page that he explains how to do it.

If you don't know how to use RMClock, The Undervolting Guide explains it pretty well.

Oh, I also just tried out CrystalCPUID and it had the option to change multipliers. I did try getting my T1350 up to x15 from the stock x14 but just got the BSOD as I thought.

 

I did use a silver based thermal compound from a tech's supply. It came in an idividual tube very similar to the arctic silver I recieved later in the week. Perhaps I didn't apply it well. I used a bit more than I thought it called for and spread it as evenly as I could. I did clean everything out while it was apart.
I have rmclock and will read the guide you linked to. Thanks.
Did I understand right that cpufsb is the short form of cpucool? In any case, I'll read that link as well. I haven't seen CrystalCPUID but will look into that.
Thanks for the links. Will update when I've read and tried the aformentioned programs.

 

I'm thinking that I should post the under-volting and OC'ing in other areas so I will be very brief.
Thus far, I've reached 1.05V for the 11x multiplier and ran Orthos for 45mins with no ill effect. temps ran from 69 to 72. My baseline temps were 84C. the hottest temps were reached at about the 5 min mark and then they came back down a couple of degrees for the remainder of the test (this was true at all voltage settings).
Thanks for the help. More work to do!!

 

Nice work with the undervolting, you should also try some timed speed tests to make sure you aren't getting rid of too much processing power. I have done quite a bit of undervolting and never came across any problems with less processing power but it never hurts to be extra cautious. Wprime is a nice program for testing that.

CPUFSB is a stripped down version of CpuCool and just focuses on the FSB side of things, which is what you want.

Maybe the thermal compound is just settling in, mine was also a bit too hot for the first couple days and then got cooler gradually. If it is similar to AS5 then should take around 200 hours of on-time to reach its full potential.

 

Thanks.
Quick question. My T5600 (ES) has min and max V settings of 0.950V for 6x and 1.250 for 11x. Is this off from the regular chips. I ask because at 1.050V for 11x, I'm only 0.100V for the total range 6x thru 11x. It's possible I could go down further, I just went to bed after the last setting. I divided the 0.100V by the five settings for a 0.02V diff between multipliers and just put those figures in. When I set it to auto adjust, the inbetween figures stayed the same as shown by RMClock (that's why I put them in manually).
I'll convert a 2+ hr. movie as I know how long that has been taking and so will get a real world (for me) feel of performance.
Thanks again
UPDATE: Did a 2hr 9min movie in 52min 50secs. Very close to pre-undervolting times. Tmax was 65C on core#1. Previously 74C.

 

Nice temps on that movie run. If you are interested you could also see if your battery lasts longer with the undervolting. I only noticed a 10 min difference on mine but my battery is already nearly dead and only ever gets 45min max.

As for the voltage settings I'm not exactly sure about the 5600 as I don't have one but those voltages sound about right. The auto adjust just sticks what it seems appropriate in based on what is the highest and lowest voltages on the multipliers. I don't use auto-adjust myself. What you've done with the voltages should be just fine.

I experimented with disabling the middle multipliers and just enabled 6x and 14x (highest on mine) as the speedsteping from 6 to 14 takes time (like gear changes on a car). The results were minimal, around a couple milliseconds.

Have you tried using a higher multiplier yet?

 

I wasn't able to access a higher multiplier than 11x (normal). It must be locked.
I tried to play with the fsb, but I obviously don't understand the pll thing. I screwed things up. I was running at 1.966 or something but my ram speed was way off (like runnng at 455 or something like that). I did run orthos for 8 minutes like that, but ended up just closing it out and restarting to return to normal operation speeds.
I'm afraid to mess with that too much for lack of knowledge!
I did have some trouble with a couple of movies in that right near the end, the converting/compression program would quit. I thought maybe it was the speed stepping that was messing things up. I locked the cpu in high perf mode and reran the movie and it worked fine.
I set the battery mode to the lowest speed and gave it only one choice, 6x at 0.95V. The computer kept shutting down and restarting. I guess that's to little power to start up and/or start programs. Maybe i'll try giving it a couple choices. I believe I got the same effect with the battery life when allowing full speed stepping.
Thanks for all the help and info. I won't be able to mess with things for a couple days, but will try again next week if I'm feeling brave!!

UPDATE: I just downloaded and looked at PCWizard. It says that my multiplier is not locked (I guess that just means it can float from 6x to 11x?)!!! Now if I just knew exactly what to do with that info!?! More reading needed!! Weird. My voltage range on insertion and pre-undervolting was 0.950v to 1.250v. After running PCWizard (while active at least) i've now seen voltages of 1.063v at 1000NHz and 1.363v at 1833MHz. Does that mean that a previous owner had already undervolted and locked the voltages (and now somehow pcwizard reset them)? It seems to me the standard voltage range for the T5600 was 1.03X to 1.3XX ? Wonder what that will do to core temps?? More testing!
I'll try to attach a screenshot.

 

A couple more screenshots with variables.
Notice the VID on CoreTemp (1.2500) and on PCWizard (1.363). My core temps at the 5 minute mark were up to 86C (just a bit higher than previous readings). They may have went higher, but based on my other tests the 5 minute mark showed the tmax for the 45 minutes tests.
I imagine you guys understand these numbers better than I!

 

lowmaintenance Can you provide some pictures of RMclock's settings? The Profile tab, the Settings and the Multipliers?

You have 6 multipliers, 6x is the lowest and 11x the highest. None of these is locked, the only locked thing is the minimum voltage, every CPU has one. My minimum is 0,95V, I cannot pass below that even though I know my CPU will be stable.

 

All CPUs can float inbetween their lowest and highest multipliers (in your case 6x and 11x). What that "unlocked" in PCWizard means is that you can go above or below the normal mulitpliers for your specific chip (e.g. 5x or 12x) but you will require a specialized program to do that (CrystalCPUID is one example). My CPU says "locked" as it is not an ES chip.

Just noticed that your FSB is running at 667Mhz as shown in PCWizard, so looks like your RAM is running at full potential.

I have no idea why the VIDs are different in PCWizard and CoreTemps. I am at a complete loss but will do some research to see if I can find any explaination. A quick search reveals that the VID range for T5600 is 1.0375V - 1.30V.

If you lock the multiplier to 6x @ 0.950V it may not have enough power to run things properly.

As for the overclocking, you need to use PLL 954310 and select Fine Tuning. From there you just need to adjust the Divider up or down depending on what you want. Below is an example:

Lets say you want to increase your clocks up to 2Ghz from 1.87Ghz (I'm using my clocks for reference). My standard divider is set at 55.8750, that figure is then multiplied by the gear (2.386) to get the FSB (133.34). Then multiply the FSB by your highest multiplier (14x on mine) to get your CPU frequency. So if I increased my Divider up to 59.8667 (by using the +/- buttons in Fine Tuning) that would make my FSB 142.86 (59.8667 x 2.386) and multiply the FSB by my highest multiplier (14x) and walla, 2000.09Mhz.

Here are some screens to help explain. Notice that i've locked my multiplier to 14x to make things more simple.

 

Is this what you need?

 

So when you have the undervolted settings enabled with RMClock what does PCWizard tell you the voltages are running at?

 

RE: the fsb;
Is that PLL for my 3680-2682?

I thought Andy got his ram up to speed by increasing the fsb? I don't quite understand the ram values with the 5:8 ratio.

I'll try that program with the multipliers just to check if the options show up.

Thanks again to all!

UPDATE: I'll run those settings and send the clip

 

Looks like they're picking up different numbers?

I ran orthos so the settings wouldn't fluctuate while assessing the voltages.

I should also mention that last night while in pcwizard, I did a re-check on my windows experience index. My video was my weakest link giving me a previous number of 2.6 which increased to 3.0 after running pcwizard. I figured the extra voltage boosted the graphics chip!?! Don't know if that's right but it was a nice side effect in any case!!

 

i943GML supports DDR2-533 max. You'll have to overclock the FSB to raise the RAM frequency.

Since the FSB is at 166MHz, and the RAM frequency at 266MHz, the memory multiplier is 0.625....(or 5:8). This will remain fixed, and the increase in memory frequency will be proportional to the increase in FSB when overcocking, with respect to that multiplier.

At FSB = 200MHz, memory frequency should be: (200*8)/5 = 320MHz. So, at a FSB of 800MHz, you should be fine with DDR2-667 modules.

 

Thanks for the explanations!
I'll be tied up with work for a couple days. I'll spend that time studying so I can ask intelligent questions (hopefully).
At this time, I don't quite understand the relationship/interaction between the various factors (fsb, bus speed, multiplier, cpu frequency, ram frequency). Voltage should be separate from all these?
I understand some of the relationships, just not all and to what extent.
I'll study, then come back!!
I appreciate the info!!
In the meantime, I'll try to provide whatever numbers you guys need to figure out my varience in numbers.

UPDATE: Crystalcpuid shows the following; multiplier range of 6x to 25x; voltage range of 0.825v to 1.613v

 

--------------------------------------------------------------------------------
Yeah I know it aint the right thread but there's more peeps here than in the 8930 owners lounge so I figured someone here might know how to help me


Just got the as8930-6058. I'm pretty impressed BUT; is the motherboard generic for all 8930 models, and can I upgrade the Dual core to a Quad core? What is the fastest CPU this board will take? What is the most mother board RAM I can put in? What is involved in uping the 512MB on the NVidia 9600 GPU to the allowable 2303MB? --And can I do that myself?

Anyone know of any system performance tweaks? Overclocking potentials?
3dMark was somewhere around 5500 after tweaking Vista 64 bit, but I want more. lol

 

1. I think the motherboard is the same for all 8930 models(so far). I think I heard something about a new 8930 with Quad but not sure.
2. Nope, you can't upgrade to Quad-core.
3. I don't know, maybe x9100, if the BIOS allow it. And you might have heat issues.
4. The chipset support up to 8GB but for now I think there is a 4GB BIOS limitation. Not sure about that though, maybe ACER released a BIOS update that support 8GB of RAM.
5. The memory allocation apart from the dedicated memory is done automatically and the amount depend on the demand. I think you cannot force the GPU to take more memory. And even if you can this won't increase your GPU's performance.
6. If I remember correctly there isn't support for 8930 clock generator so for now you can forget about overclocking your CPU. You can overclock the GPU though. Check the Aspire 5930 owner's lounge the people there are currently overclocking and getting an amazing results.

 

Forget multiplier management. Setting that is a PITA.

Go into Function > Intel Enhanced Speedstep Control > Enable Change Voltage > Don't touch the multiplier (it might crash), just run Orthos/Prime95 side-by-side, and keep lowering the voltage until you find the most stable one.

When you get the lowest, stable voltage, make a shortcut for it on the desktop.

 

I started a separate thread called "overclocking a t5600 in acer 3680.
I posted a shot of myfirst attempt there. Not overly pretty!
Thanks for all the help!!

 

Holy It work ! so excited this machine flys compare to the celeron man wow
need memery now !

Thanks everyone !

Paul

 

no problem paulrich

Congratulations on a clean install! What CPU did you stick in it?

Other things you could do to speed it up include:
-More RAM (3.5GB max for 32-bit Windows)
-Faster HDD e.g. 7200 RPM (vs the 4200PRM stock HDD)

 

Took me like 30minute to drop in a T5300 cpu $80 booted no problem.

true more ram and hard drive would be well worth it.

this is fun haha

anyone want to buy my orignal cpu lol


Paul.

 

What a recommended temp for the cpu ? I am reading 61c

 

That depends, if that is an idle temp then it is quite hot but if that is under full stress then it is quite a good temp.

If you want to try and get the CPU cooler by undervolting then you can follow what lowmaintenance has been doing.

 

its idle. ok I gona put thermal paste on it. I rub some of the old cpu to the new
cpu maybe not enough.

Thanks

 

Mine maxes out at 62C under full load

Yes, thermal paste should fix your problem, I'd suggest AS5 or the newer AS-MX(i think thats its name). Also while you have it open make sure to give it a good cleaning, namely the fan. Also avoid touching the vital organs of your laptop with bare skin (use latex gloves if you have any lying around). The reason for this is the oil from your skin could get transfered onto the electronics and if they get too hot it could get the oil boiling and that ain't a good thing. I used to build race engines so I still use latex gloves and a face mask whenever I'm working with anything sensitive, and yes I know that is overkill but it pays to be safe.

 

Sweet thanks for the tip, I just got out hospital a few days ago
and kept some glove they left in my room haha I knew it could be useful
even have the mask for germs I could put that on lol

Hello again,

Sorry if I shouldn't be reposting here about my upgrade/overclock.

I did my reading and learned the relationship (if only on a basic level) between the various system speeds.

I'm going to leave my settings alone (overclocked as seen in the attached screenshot) for awhile and see how the system runs under normal use.

I ended up using cpucool to up the bus speed to 185.5 (It would only go to 189 max, no matter what cpucool was set for, it never read out at more than 189 per 3 different programs (crystalcpuid, cpucool, and cpuz).

That puts the cpu at 2040 (11% overclock) the ram to about 594 (up about 11% from 533) and the FSB to 742 (up 39% from 533).

I was going to up the bus speed to 208 to get memory up to 667-ish and drop the multiplier to bring the cpu back to a reasonable overclock as well as undervolting to keep things running cool.

I ended up with what you see in the screenshot. That's where i'm going try it for at least a week. Don't know how this will affect video converting yet, but will test as the week progresses.

Thanks again for all the good input and info. This thing flies, now!!

 

Fiddling is the best way to learn, well at least it was for me and luckily I didn't fry my computer while I was at it.

Might be slightly off topic, but I just received my Clevo M860TU today, and boy does it put the old Acer to shame. Right now it is idling at 25C... and then it maxes out around 48C (all this without undervolting) which by the way was my idle temp for the Acer.

Let me know how the stable the overclocking works out to be.

 

Hmm....usually such CPUs are not calibrated properly when still in the factory. Or the codes for that particular CPU are screwed up in the ACPI tables.

(Even my atom and Celeron ULV struggle to go that low. )

 

That was in regards to the Acer right?

 

The one with the 25C idle.

 

Have you had a M860TU? It has the best cooling system in a 15" laptop, even with a 9800GT and T9600 the temps rarely get above 60 during gaming.

 

Thats not my point. There are loads of CPUs which are not calibrated properly at the factory level, esp Intels, since they are produced in massive quantities. These CPUs show incorrect temperatures even in the BIOS.

Standard ambient temperature is assumed to be 22*C, since that is the temperature a normal human being lives in, the CPU temperature (Tcase) is always higher than that, and the core temperature (Tj) is even higher than the Tcase. There is absolutely no way a CPU in a notebook with 2 fans and a decent airflow, can 'actually' idle @ 25*C. The Tcase usually remains higher than the ambient temperature even when the computer is off, unless you have your notebook in the freezer or right in front of the air-con.

My motive was not to start an argument, but to only correct the flaw in your logic. I don't really care that you're comparing a Clevo with a Quanta/Wistron/Compal etc. I have a desktop which has better air cooling than any notebook has or will have in the next couple of years, and I have never been able to to reduce the idle temp below 35*C without undervolting.
