Acer Aspire 5740G Owners Lounge

where is a photo that replaced i330 vs i7 620 m? link in pvt plese

 

For the hell of it, I did a teardown of this 5470g, and while I didn't detach the HSF ( no spare thermal paste handy ), the socket and latch are clearly visible.

If you take a look at the Aspire 5738G service manual, it's a similar socket.
The 5740 doesn't stray too much from those pictures in design or placement of components, including the HSF. These aren't cross-compatible ( without some work ) obviously.

Overall I'd give it a B- in serviceability, although if you really want to say
clean the HSF out directly, you'll be doing a full teardown...

The question is whether or not the all the 5470's support the full range of i7m's as an easy swap.

On a side note, the HSF is pretty good, assuming your ambient is reasonable.

The 5650 in this unit gives me 725core and 915mem, enough in a warm room
to overwhelm the stock HSF and cause the i5m 520 in this unit to throttle down at load, while the GPU is just peachy.

Still looking at a BIOS mod ?

I don't really think laptop coolers are all that effective, but the range
people have been able to get out of the 5650's clocks might make one worthwhile where ambient isn't controlled. Particularly with higher end core iX-m's and their slightly higher thermals - might make a difference as the CPU shares a combined HSF with the GPU.

 

hi all !

I am looking for someone who troubleshooted this external disk issue..

I have a Acer Aspire 5740G laptop, Windows 7 by default.

I tried to plug my Toshiba Stor-E Alu external disk and it appears like not recognized by Windows... ( plug -> "windows will install driver" -> "windows cannot install this driver" -> fail... )

Of course, this disk works on another laptop and on Windows 7

I tried to :

- reinstall USB device driver
- reinstall USB hub driver
- copy usbstor.sys into c:\windows\inf
- install all Windows updates
- install drivers & firms from Acer website

If anyone got a brillant idea ..

Have a nice day !

Hello,

What is the ICC color profile do you use for 5740g?

 

but the flat cable??????????????????????????

 

Apparently this guy over at Noticias 3d forum says that the i7-620m is not compatible with his 5740G. He says that it might be because of a HM55/PM55 issue.

Please note that his laptop came with an i3-330m as default.

 

Actually, it is not HM55/PM55 issue (because if you said issue, it kinda a hardware problem which is not in this case). i7-620m just not compatible with 5740G. I'm not sure exactly why it doesn't compatible but maybe because combination of chipsets make it incompatible. On Core 2 Duo notebooks, I found I/O controller play important role determining which processor supported & which are not.

Actually, 5740G came with several configurations, from i3 to i5. The two configurations I know are i3-330M & i5-430M.

 

The only problem is that official Acer website claims this notebook is available with i7-620M. Not that it is on actually sale with it but still it's supposed to work...

 

Besides...the acer 5745 has the same Mobile Intel® HM55 Express Chipset like the 5740g...and is available from core i3 through i7...so I would think as well that it should work. (but not worth for me to upgrade)

 

You can't compare like that. 5745 is a different series than 5740. Compare both BIOS (especially CPU microcode). Perhaps it just simply update the CPU microcode to support i7 CPU.

 

I know that it is a different series...all I wanted to say is, that I don't think the HM55 chipset is the problem to upgrade...like somebody earlier here mentioned. (from Noticias 3d forum )

 

Yeah, little misunderstanding on my part.

I already take a look on Intel website for compatible chipset for i7-620M & other i7 CPU but I don't see it require anything except PM55, HM55, HM57, QM57 or QS57 chipsets. Core 2 Duo CPU compatibility with (notebook) motherboard is depend on chipset & IO controller hub. I hope it just need to update CPU microcode on 5740G. However, it is easy to said than done.

 

Hi,

this is the 5740G with the i7-620m. It´s from a Spanish retailer.

5740G-624G64Mn

It has the same components as my 5740G, only 4GB RAM versus 6GB mine has.

Cheers

 

This ruled out CPU microcode in BIOS. Unless the guy at Noticias 3d forum bought faulty i7-620M, definitely the Spanish's 5740G (to be exact 5740G-624G64Mn) have different motherboard than other 5740G. It has been known that Acer sell different configuration on different region on same model. This obviously upgraded version of 5740G.

 

I don't fully understand you- the guy at Noticias 3d bought his 5740G in Spain and the link alstrike provided is also to a Spanish retailer hence Spanish version of 5740G. I guess the CPU had to be either faulty or a fake.
Sorry if I misunderstood your post but I wrote this one the run...

 

You just repeat back what I said earlier on my previous post:-
"Unless the guy at Noticias 3d forum bought faulty i7-620M, definitely the Spanish's 5740G (to be exact 5740G-624G64Mn) have different motherboard than other 5740G. It has been known that Acer sell different configuration on different region on same model."

 

I´m from Spain and my 5740G is spanish obviously. The link I posted earlier is from a major retailer in Spain.

The i7-620m is 5740G-624G64Mn, mine is 5740G-436G64Mn.

That model and mine have the same socket, the same chipset, the same motherboard, the same GPU, the same HDD model, etc... Something clearly doesn´t add up.

My money is on a faulty CPU.

 

I use the following one:
http://prohardver.hu/dl/cnt/2010-09/64827/Acer_5553G.icc

 

I'd like to greet everyone as this is my first post at these forums and also it's the first post I'm writing on my new 5740g. So, hi everyone!

And coming back on track , I'd like to ask a few questions about this lappy.

HWMonitor is reporting about 4*C temperature difference between Core 0 & 2, no matter if it is in idle or under heavy load (w/ linpack). I even changed the thermal paste for Liquid Pro and the issue is still there.

But overally after Liquid Pro appliance the temps dropped from 71* C to 61 on CPU (i3-330m during load with linpack) and from 71 to 64* C on GPU (5650 @stock) under stress with FurMark (for 10 mins), so the paste's performance is really amazing. Now the fan doesn't turn itself on so often. (but temp diff between cores still persists).

I believe the radiator isn't straight and so it doesn't adhere well to the cpu. What do you think?

My second problem is the construction of air inlet - only half of it actually lets air in because the second half isn't even properly cut out. Is this only my model's issue?

Thanks in advance!

 

has anyone been able to find a place that is still selling the 5740G? i'm going to be putting mine up for sale soon in the marketplace, i just want to get an idea of what i can expect to get for it. any help would be appreciated.

 

I bought mine in Poland few days ago for 2349 PLN or 803 USD or 589 EUR. It has i3-330m, 4 GB, 250 HDD, 5650 and bluetooth. And that's the least price for this config.

i5-430m with 640 GB but w/o bluetooth (rest as above) costs 2699 PLN or 923 USD or 677 EUR at the least price.

Hope this helps.

 

Mine has the i5-430m, 4 gb ram, 5650, 500 gb hdd. I was hoping to get at least $700 for it. I think that is a fair price, since you can't really find it anywhere in the states anymore.

 

You can try but you have to offer it at lower price than new 5820TG is sold at- otherwise it's pointless.

 

can you provide some links where this model can be purchased at? i haven't seen any retailers selling the 5820TG in the US.

 

IT WORKS!!! THE i7-620m FINALLY WORKS!!!!

Apparently the guy over at Noticias3d forum (starsay) apparently didn´t place the CPU properly in the socket and the motherboard didn´t recognised it.

But now...

P.D. I might get an i7-640m and not sell the 5740G after all...

 

At last, good news. With pictures too.

 

The only thing left is the BIOS MOD issue, so we can use the IGP. When that happens I´ll be so happy...

 

wait, was this a successful CPU swap in the 5740g?

 

Yes it is, only is not a 5740G but a 5740 (no ATI GPU, just Intel Media Graphics)

He went from an i3-330M to an i5-430M/520M to an i7-620M.

I LOVE THE GUY.

I´m ordering an i7-640m myself, it´s like 15$ difference from a 620m...

 

amazon is selling it for 717.99 $
and it has even Switchable graphics

Amazon.com: Acer Aspire TimelineX AS5820T-5951 15.6-Inch HD Laptop (Black Brushed Aluminum): Computer & Accessories

 

yeah but that laptop isnt nearly as good as a 5740g... its only an i3 with intel HD gpu. so i would think 700 is a great deal on a clearly better system.

 

Could someone reply to my post ( http://forum.notebookreview.com/6751091-post2121.html) please? i'd really appreciate it. I'm a little worried about that core temperature difference. Do you guys have a similar temp difference in your 5740Gs?

 

It's fine. There's always a little difference in temperatures between cores.
Your notebook is definitely not overheating either so don't be bothered by that.
The inlet is half-open in all 5740Gs not only in yours and as you see it doesn't affect the cooling. As a matter of fact it's been done on purpose probably to channel air so I wouldn't try to change it.
Aspire 5738 had the inlet completely closed- that was something different but 5740G has really good cooling system and low temperatures compared to other notebooks so there's no reason to change something that works.

 

Thanks for the quick reply. I really appreciate it!

As to overclocking my 5650, I managed to acquire stable clocks of 725 MHz on core and 995 MHz on memory during 3DM06 tests, so Mobility 5650 has really a great potential to overclocking. For being completely safe and to not strees the GPU much I will stay with 700 and 960 MHz. I got this clocks with changed thermal paste - Coollaboratory Liquid Pro.

Previously I had a Dell Vostro 1500 w/ T7250 2.0 and GF 8600M DDR2 and despite the DDR2 (on GPU) the laptop was REALLY well built (quality keyboard, touchpad and overall sturdy and well-considered construction). Cooling was so good that the fan didn't turn itself on even during watching a DivX movie, because despite processing video the CPU stayed quite cool (about 50*C with the fan off; 38* in IDLE). Of course it had some flaws like low quality LCD panel and headphone output making some noise. But all in all, the Dell was of great design.

So after such an enormous impression upon Dell I was little worried with the Acer's built... Before I opened the box with my new lappy! Keyboard may not be as good as in Dell but it's not that bad either. Touchpad is more than ok, comparable to Dell's. I don't like HDD led's placement - it should be posistioned near battery led. Power button's blue light also annoys me a bit. Next time I tear down this lappy I'm gonna remove its led. But anyway, those are things of only little importance. What I was really worried about was the cooling system. And to cut long story short - it does a great job (and the Dell's was even a bit better). I like my new laptop. I know I coudn't find any better for the price.

Cheers

 

very nice clock speeds you got there daerragh, i haven't bothered trying to go over 700 mhz on stock thermal paste, as I don't really see any reason to push it that far

 

That's not a 5820TG; it is a 5820T. It only has the Intel GMA HD. It is missing a discrete video card and therefore, has nothing to switch graphics with. Just letting you know.

 

@Omgzilla85: Yeah, 5650 has really good performance so I too don't bother to keep the clocks at max level. I wanted to OC it that high just to know how much I can push it

 

Yeah, you guys are right! I guess I was too quick with posting the link...but I saw some other websites with this 5820TG and supposedly it has the ati5650with switchable graphics. I don't care too much anyways because I'm happy with my 5740g. But I would not buy it used for $700 ... good luck though omgzilla85!

 

yesterday while playing nba 2k10 there was continuous lag after every 15 sec and temp of gpu and cpu was also in mid 90. I never had such temps before. I have attached a snapshot. The gpu drivers are also updated ones. what could be the reason...?

 

i wanted to know if my ati 5650 would work fine in ubuntu 10.04 64 bit
i have checked the ati.amd.com and there are drivers for the 5600 series
ATI Catalyst? Proprietary Display Driver
https://a248.e.akamai.net/f/674/9206/0/www2.ati.com/drivers/linux/catalyst_109_linux.pdf

i wanted know whether ubuntu can damage my hardware or any parts of the laptop as of drivers issues or un supportedness of my laptop ??

should i use ubuntu 10.04 64 bit ??

 

@freaky_champ: Was the laptop hot? Maybe HWMonitor somehow broke and shows wrong temps?
Is your fan working fine? Didn't it broke?

If it was hot I recommend you NOT play any game or even watch any movie (or do any other cpu/gpu stressing task) until you have fixed the cooling system (because it is NOT working properly). To do that you either give your laptop back to service or you do tear it down yourself, apply a new thermal paste and make sure the radiator is well screwed on to cpu and gpu.

The temps you have are REALLY bad and your cpu and gpu might burn, thus becoming unusable. If the cpu is burnt, you might replace it with another one but the gpu core is integrated into the motherboard, so if it dies your only option is to replace whole motherboard.

 

if u had kept lappy on soft surface, then it might hav blocked the ventillation vents, if not then better get checked by service people

 

If yours still under warranty, send it to Acer service center. Your hardware should be OK. Usually high temps only caused by too many dust at FAN (or board - which can disrupt the air flow) or the thermal paste already melted down (poor quality). If yours already out of warranty, you can either send it to service center for cleanup/check but of course it will cause you money or you can do it yourself. Opening the case should be easy & you can refer to service manual for other Acer notebook, preferably the one which shared similar casing. I have cleanup two notebooks before & usually I just clean the motherboard & FAN. The result is no more overheat & it run much cooler. Of course, you will need to disassemble it completely (tear down) because you'll want to make sure all surface clean from dust.

 

no it wasnt that hot.. i could see the variations in temp .. it was in the range of 85-90 and max it reached 98.. and that was scary. . The laptop is jus 3 months old i bought it from US and i stay in India.. should i take too one of the service centres here in India... ?

 

Yes, better take it to service centre until sth bad happens to it.

 

Got some pretty important information.
I'm 99% sure that clock generator on 5740 series is ICS9LRS3197AKLFT
Also SetFSB supports Aspire 5740 in the most recent version (it's on the list as Asus N61JQ but should work on most of these: ASUS N61JQ/N71JQ/N71JA, DELL Alienware M15x, Acer Aspire 5740/7740, Packard Bell TJ-75)

As for the clock gen it's official Acer info so I'm pretty sure it's accurate.

So if anyone has some free time on their hands and interest in OCing the CPU...

 

I would try but the latest versions of setfsb are only shareware with disabled overclocking functionality. Is there any free app that supports 5740's PLL?

 

I think 99.5% you're correct since Packard Bell TJ-75 is actually a 5740G clone.

What happen if you set to wrong clock generator on SetFSB? Will it be just not working (changes will no effect)?
