Acer Aspire 5740G Owners Lounge

At my laptop the max temperatures rised at 80*C GPU and 84*C CPU without overclock from 74*C GPU and 76*C CPU 2 weeks ago , in every game. Why the max temperatures raised soo much?

 

That depends on ambient temps to a degree but mostly on a game.
You would have to compare it in controlled environment- the same test, the same length of the test.
Otherwise all it takes is 2-3*C increase in ambient temps and a new game and/or different time spent playing and you have an explanation for 3-5*C that you are missing.
Still you may want to clean the vents just in case.

 

Ahhhhhhhhhhhhhhhhhh... can't even open this laptop.. Gotta remove even motherboard to get to vents... so sad sh*t !!!

 

Hy Guys,
I bought today this laptop, after watching almost the whole forum discussions and other sites on internet.Untill now everything is OK. GPU-z reports 50-51 degr Celsius with ambient of 24-25 Celsius.
However, a nasty thing I observed (I had before a Toshiba Satellite A200) when watching video clips there seems to be some kind of "moire" or "raster" effect on the image at the pixel level. It's like having a raster of gray pixel superimposed over the whole image. It's also present when scrolling fast some webpages. I definitely think it is something about Acer, because I was in the showroom of the company from where I bought it (I'm in Europe, Romania), and a 5738 had the same weird effect. Has anyone observed this?It's really a shame, because all things taken into consideration, the laptop is very good.

 

I'm not sure if we're talking about the same thing but there's some "graining" visible when you look at the screen being slightly up or down- it's not Acer specific- it's something to be seen on all LED backlit LCDs.
That's provided we're talking about the same thing

 

anyone knows?

 

Yeah, but your question couldn't have been answered easily since direct links don't work for Realtek so no one knows what drivers you linked to.
You should download "Vista, Windows7 Driver(64bits) Driver only (Executable file)" 2.51- that's if you are using 64bit Win 7.

 

Hi downloads was wondering if you have a new link to updating the synaptics touchpad driver? The link on page 1 is broken.

Cheers bro

 

Yes, it might be described as graining (as you would pour some gray pixels over the image, don't know how to explain better), BUT is visible no matter the vertical angle, and definitely no, I have not seen it on a newer Toshiba L650 I had 5 days before this, not to mention all other Laptops in the showroom (about 30 different models). Clearly if you looked on the Acer Aspire displays you would feel the difference compared to the other laptops. For me also it is very weird, as I have quite some experience with laptops and I never saw this kind of effect. Not like blur because of latency of display, not like anything else, but disturbing Do you know of any other places where people talked about something similar?

 

I'm on it

EDIT: Done. Thanks for the info.

Not really- I've read in a review that it's due to LED backlight but that's all. It may be sth else in your case though- play with CCC settings for display colors and LCD optimization- maybe it requires some tweaking. BTW who produced your LCD panel (use Everest to check it)- I'm asking out of curiosity.

 

My windows sticker has worn-out. Any way to get the serial-key? Because i want to do format-c and sell the laptop.

 

You can use "product key finders" tool to obtain your windows key.

 

It has nothing to do with LED backlightning as a technology - I've seen plenty of them and none of those had this problem. There's clearly visible dynamic noise especially when the image is dark. I have AU Optronics BX156XW02 V2

 

We're definitely not talking about the same thing- the one I talk about can be seen only when the image is not dark- white or gray. That supposedly has something to do with LED- there are two ways the LED backlit may work. The one that causes what I describe is Edge LED- more common in notebooks than the other one. Anyway I don't insist on it- I'm no expert in this field nor do I intend to spend a lot of time researching it (I should be working right now )

 

Well... this week I saw that CPU and GPU of my 5740G hiked upto 100 °C while playing games... these are the temperatures I had while playing Batman Arkham Asylum... I had almost same temperature while playing GTA IV and Crysis... and yeah, i haven't overclocked my GPU, its at default clock...



And these are the temperatures while I did usual browsing (no videos whatsoever) and listening music



I don't know what is the ambient temperatures but I have CPUID running at system start up and the minimum temperature it shows is 44 °C,, so I guess it would be around 40 °C

I bought my 5740G 3 months back, so vents are pretty clean...

Should I be worried about the temperatures?

 

CPUID temp shown on startup is no indication of ambient temp. It kicks in and records a temperature just after windows had started which is at least a minute or two after you had switched on a computer. It's like measuring the temperature of a light bulb two minutes after switching it on- it not ambient temp.
More to the point- does you fan work properly? With temps like these it should be really audible. Can you verify those temps with some other software- Everest or GPU-Z for example?
My surfing & music temps are 43-50*C for CPU and 50-53 for GPU, HDD is between 41-43*C. with ambient temp of 28-29*C
Under load and OCed I don't get more than 78*C in GTA IV.

So either it's hot as hell where you live- and I mean as hell- some 50*C, your cooling system doesn't work properly or the monitoring software is lying.

 

CPUID Hardware Monitor reading does accurate, no doubt about it. If the ambient temperature are around 34C to 35C & with bad airflow, the temperature can be high, just like what rahul.never2far got. It does too high. I bet the thermal paste have melt down or too thin (bad quality).

@rahul.never2far, you will need to send it to Acer for repair.

 

No it couldn't. I had the (doubtful) pleasure of living in such temperatures just a week or so ago and I never got within 20*C of what he has even though mine was OCed.
Since we both have the same notebook the bad airflow you mentioned would mean stuffing a rug into the air inlet or something.

 

Yes, you have identical notebook, however, rahul.never2far's notebook may have poorly assembled in the factory. I'm also have the experience living in such temperature too. What I meant for bad airflow is, the hot air is not dissipated from the notebook efficiently because of the (maybe) poor quality of the thermal paste.

 

Yeah I know what you meant- I was just kidding about the rag nonetheless the only way this could happen is if there was no thermal paste on both GPU and CPU heatsinks. I wonder if rahul.never2far had previously taken note of the temperatures. I mean did it get any worse or was it always like that?
Also I would insist on double checking these values with another app- I know HW Monitor is reliable in general but still it's the easiest thing to do.

 

I think the gpu temperature raised because of catalyst 10.7 , i tried to uninstall the 10.7 , and installed 10.6 from softpedia , but the video driver don't installed , just catalyst center , and when i installed just video driver from amd drivers , in the catalyst show again 10.7 , how can i downgrade it to 10.6?

 

Yeah, I agree, at least use two tools to read both CPU & GPU temperature, just to confirmed the first reading. The ATI Radeon HD 5XXX series have reputation to be much cooler than the 4XXX series. The i5 temperature also too high (I can't believe my eyes), just like you said, as if there is no thermal paste between the CPU & the heatsink.

 

No... the fan is not really that audible...

I just checked the temperatures with GPU-Z... they are pretty much the same...

Air inlet looks clean...I bought my 5740G 3-4 months ago... so the air vents must be pretty clean...

Yup I did... I remember when I started taking note of temperates, the max temperature used be around 80C :-(

May be I'll have to take to Acer service center...

A friend of mine bought same notebook as mine on the same day... I'll call him today and take note of temperatures of his notebook and post here the results

 

There may be something wrong with it then- when CPU temp reaches 80*C "panic speed" kicks in- that’s when the notebook reaches 37dB- so it should be pretty audible.

 

Did you guys check what BIOS version is he using the fan is BIOS controlled.

 

Do you know what is causing the noise? Because I have it too and was wondering...

 

As I wrote earlier- if it's slight "graining" to be seen when the screen is pretty bright and you are looking at it from slight vertical angle- it's supposedly caused by edge-LED backlight.

 

Guys, about the graining, I stayed a little longer on the issue and what I saw today was:
-if on a static gray background i moved my eyes fast on left-right, I had the impression of "graining" - on the corner of my eye.
-if I focus on a specific spot and I can see that the gray color is not "stable", meaning the pixel each vary in intensity fast, similar to the no-signal noise image on old TV's...BUT this might very well be my mind who's going haywire as well )
Note that I was looking perpendicular to the display, not vertically angled at all.
However, I can say for sure that I made my mind and I will keep the notebook, even with the grain effect - a secondary bigger LCD will be the main screen and best resolve for this issue. I simply can't ignore the stellar performance at all

 

In mafia 2 demo after 10 minutes the max temperatures reached 83*gpu without overclock and 85* gpu with physx activated . How i can downgrade ati catalyst to 10.6 to see if the temperatures are cooler that now , because before update to 10.7 the max gpu temperature was 75-76* overclocked at max (700/980) after hours of play and now without overclock the temperature raise over 80 in every game after few minutes.

 

i5 430 w/ 1gb ati card (5740g-6769)
So its been a while since i have been combing this thread, and i have a question.. more like a .. why.. So.. i have batman Arkam Asylum installed on the computer. I launch the game.. and can play it on "MEDIUM" detail at max resolution. I went into my ATI catalyst control center, and turned off "use application settings" and set my AA and other settings in the control panel halfway to performance and halfway to quality... so NOW, i can play Batman at VERY HIGH settings, with EVERYTHING ON, at MAX resolution (i play 1 resolution setting lower cuz when there is 10 guys on the screen it gets a LITTLE slow)....

why... oh why.. is this happening and why does my graphics card NOT work without the "use application settings" setting turned on.. i would THINK that, with that on.. it would work BETTER than forcing the AA and AF and all those settings in the control panel. I MIGHT have asked something similar to this before, but i dont ever remember an answer... .. and Is it BAD for my GPU to do this? i mean when i run the game on my 1900x1xxx 42 inch LCD HDMI out, i have to turn the settings down to "HIGH" settings but its PERFECT... just wondering

(and to anyone who is playing games on Medium, TRY THIS its amazing)

 

Got a problem with my 5740g. Two audio CDs (Images and Words and A Change of Seasons both by Dream Theater) play back with a very distinct audio crackle when I try to play them, as do tracks ripped from the CDs. The two CDs play fine on both my Xbox and another laptop running Windows XP.

The 5740g plays other audio CDs fine, as well as DVDs, and rips from other CDs also play fine. The crackly CD problem is present on three different media players. I'm at a complete loss here. Would appreciate some help/ an explanation. Thanks in advance to anyone who can shed some light into what could be wrong.

 

Done a little more research and its apparent that it seems to be a problem with the TTST drive across quite a lot of laptops, anyone else with a TTST drive with this problem?

Edit: Done some more research, apparently the problem with CDs published by Warner Brothers and their subsidiaries: Suprise Suprise, the CDs are published by Atlantic Records, who have links with Warner Brothers. It seems only Toshiba has released a fix and said fix doesn't work with the 5740g.

Also, apologies for the double post, long time lurker on these forums but don't post very often and I haven't quite got to grips with the edit function.

 

downloads i have the same problem plz tell me if it normal or real problem in the laptop?!!!!!!!

 

Do you guys use the Ati CCC, or do you adjust all settings from the game you play?
Wondering that, because i still have this Phobia that the game i play stutters for mili-milisecond when it has to load. But I don't know how to fix it - I don't think it is the GPU, because I get even more Points in 3Dmark than initially posted here. I don't think it is also the CPU, since i Get more score than my cousin's Desktop. Yet, i still notice these...Stutters? Chokes? mIli-seconed Slows and Ups? Maybe it is only natural? Maybe it is the low Bandwith of the Video?
I don't know. But it seems that i notice them only on my laptop ;/


P.S: Quick Question to WoW players here: What Settings you play your game on? VSync:On/off ; triple Buffer:On/Off ; Multisampling:1/2/4/8, Texture,Shadows,Terrain etc.

 

Guys. I can't be sure we're talking about the same thing. If there's a problem it's not the notebook but the quality of LCD panel and since different panels are used the quality also differs. Mine doesn’t have a problem- that's what I'm sure of. It's a mid-range notebook so it doesn't have the best and most expensive LCD panels. Answer yourselves this question- do you have a problem with it or do you think that the LCD panel could be better?
If it's the latter then- yes it could. You can buy such notebooks but these are more expensive- and that's probably why you didn't
So if you are worried there may be a problem with your laptop you shouldn't be because most likely there's no problem at all.
If you don't accept this kind of picture quality- that's a different matter but still not a malfunction.

It may be due to game engine. I've played several that had this problem and I'd blame it on drivers or slow HDD if I had not previously read about it being engine related.
It may also be due to HDD (use QuietHDD if your HD is Western Digital) or AV software. Do you have this issue with one game or all of them?
To answer second part of the question - I never use CCC, what's more I've removed CCC.exe and MOM.exe from startup. The best way is to leave CCC settings as they are and fiddle with game settings. Forcing something via CCC is last resort. Sometimes you have to if AA cannot be set via game settings but most of the time it's not the way to go. You shouldn't ever play with texture quality, mipmap detail level and so on- it improves fps but degrades quality and works on all textures in all games (unless you use some kind of profile)
Again it's much better to lower one or two settings one in the game and leave the others as they are.

 

I play wow and was noticing those stutters. What resolved them in my case was QuietHDD.

Settings are: Vsync on, triple buffer on, multisample 2, textures high, shaddows @30%ish, terrain 50%

 

hey guys ..me using the same laptop...i have encountered a problem..i was using the ati catalyst control center that came with this laptop ..but then i decided to upgrade it to 10.7 catalyst ...but the moment the installation finished..and the ati catalyst control center was to start..and eroor came up saying... "catalyst control center host application has stopped working "
and there are some options listed below it..
to check for a solution online
to close the program
to debug the program

both the first and last option dont yield anything fruitful...
please if anyone has faced the same problem please help

 

I had the same problem once....reinstalling the software and rebooting solved it.

 

the same happens to mine lcd , the gray area seems that the pixels move fast varying in intensity similar to no signal noise !!

mine is samsung sec4141

 

And both of you have the same LCD panel...

 

^^ will it harm my eyes ?? or is it ok for this cheap lcd ?

should i change it or leave it ??

 

Nah- I don't think your eyes are at risk- it's just not the best LCD panel but it's not dangerous. If it really annoys you or spoils the fun of using the laptop maybe you should think of a new LCD panel or an external LCD display but not just for the sake of it.

 

Thanks, Yes and
No,no,no.

By stutters I didn't mean the once being fixed by QuietHDD. Yes, I had these too, but solved them. And those were no mere stutters, they were game FreeZers-up to 5 seconds!!!
What I mean is really little...almost unnoticeable, for like 0,2-0,3 seconds. Feels like the Game loads Textures. The Greater the Multisample, the longer they occur. And again, by longer, don't mean I talk about a second or more. 0,2-0,3 max. A friend that also has this laptop tells me that in some older versions of the Call of Duty, his games does that too. Another, with Sony Vio (is that how it's spelled?), said that when he enables Vertical Synch. his game would often stutter... like minor cuts.
Thats why I asked about them. And that's why i asked whether they Could be due to the low Bandwith of the Video Card: 24GB/s.(28 Bg/s Oclocked). I suppose that this is the way textures are being loaded, but why is then the Laptop so sensitive to them?

And yeah, Downloads, only in some games they appear- WoW mainly (since i play it most). I used to have them In Counter Strike Source. Funny thing is that when I removed the Vertical Sync. they were all gone. But in other games it is better to remain with VSync. So at the moment I am really confused what I should and shouldn't remove/add. Thanks for the info About the Ati CCC. One more question there- Should i completely remove these .exeS you told me where from the Ati CCC? Do they get in conflict with some other Drivers? Anything useful that would synchronize the load of textures (again, I only presume it to be texture loading) or...smth. else?

Thanks again, sorry for taking your time, but I can't help myself since you are all so helpful here
Thanks.

 

Don't remove those exes. If you do not use CCC on regular basis there's no point in stating them up when system starts- you can still manually launch CCC in the same way you do now- it just takes more time if those processes are not already running. That's all. If you deleted it you wouldn't be able to start CCC at all.
It seems those stutters are engine specific- in some games v-sync improves your gameplay on others it doesn't so you're gonna have to figure it out for yourself. I don't use v-sync at all.
As for memory bandwidth- it's not the cause of your problem. If the bandwidth is too low the framerate in general is low- not stutters but low all the time because GPU isn't fed by memory at the rate it needs to so number of rendered frames go down and stays that way.

 

Hello friends i need your help.
I have laptop Product Model: AS5740G-434G64MN and i have a problem.
