An Optimization Guide for the Asus G51

Is there any point in risking it? I mean you can't argue with the notebookreview's temperature picture. http://www.notebookreview.com/shared/picture.asp?f=45964

 

I don't think those are the temperatures around the keyboard. Every time I've seen a temperature layout picture like that it's for what the heat is inside of the laptop/360/whatever, not what the temperature is on the outside.

If my left palm rest was 94C I don't think I would be using my laptop too often.

And if those temperatures are in Fahrenheit I don't think I'd be taking my laptop outside or carrying it to class much.

 

Feeling and believing are two different things.

 

If you put your hand on your table and then put your hand on the chasis of your laptop, you can clearly feel a difference in temperature. And it's not like 94ºC is that hot anyways; I mean the average person takes a shower with water at 107.5ºF...

And I really don't care what you choose to do. I just don't see why you would be willing to risk messing up your screen just so you can close your laptop.

 

Yeah, 107.5F. 84C is 201F. That would denature proteins, melt skin, boil water, etc..

And the differences between how the table feels and the laptop is just relative temperature. I'm not saying the laptop keyboard isn't warmer than room temperature, but it's definitely not anywhere close to 94C.

And if those temperatures are in fact Fahrenheit, then I'm in trouble because summers in Maryland tend to hit those temperatures. IF the laptop screen can't handle that I've got a problem.

 

*Nothing is real*: No offense, but that's just not true. The upper surface of my notebook stays fairly warm, but that's it. As far as the pic goes, either it's F (in which case it's not bad) or it's in C and has to represent the interior temps (still doubtful given that the diode on the GPU barely hits 93C).

If the GPU diode says 93C and the interior temp at the left palm were 94C, that would violate thermodynamics. It would assume *greater* than 100% transmission of heat, or very near 100% (assuming your GPU was running at even something like 97C). No way.

Bottom Line: I'm not sure who told you this, but it's total crap.

I've owned much hotter laptops than this, and had no problems whatsoever with what you're describing, including a Toshiba convertible tablet (where the screen folds over) where the screen was routinely subjected to high temps from direct contact with the laptop chassis for hours at a time. And that's a *running* laptop, not a rapidly cooling one you just turned off.

 

Yeah thats just stupid. I've never heard that anywhere.

 

I would suggest against closing the laptop lid while gaming or doing anything GPU intensive. While not a heatsink, the uper surface still lets some heat pass through. And like NiR said, LCDs and heat don't play nice together.

For more mundane things, go right ahead. I've run uTorrent (Which pwnts Azureus, but that's for another thread, I think) for ten hours straight and my highest CPU was 47/45 and GPU was 55. Lid was closed. I was undervolted at the time, but still.

 

Well, of course. But he was saying to wait some time after shutting down the notebook before closing the lid, which is (sorry) rather ridiculous.

Also, how exactly do you game with the lid closed?

 

Guys, my mod v2.0. I started a thread as well in case someone else comes up with a better solution.

I'll post data soon, but despite it looking pretty nice, it doesn't seem to do much. Oh well. It was kinda fun anyway.

For the next iteration, I think I'll paint the fan shroud black. Why not?

 

You could have it hooked up to an external monitor.

 

You got me there. That would be pretty insane.

One last pic to show that it looks pretty factory IMHO:

 

Looks good I have to say,but tell us if you got any temp improvements after this mod?

 

I meant Fahrenheit, and I never said anything about waiting to close the computer after you shut it down; I was saying that sustaining 90-100ºF or higher temperatures blowing against an LCD screen is not a good idea. Do whatever you want though.

 

where do i look on CPU-Z to tell if i overclocked my processor? core speed or bus speed. My core says 1866.2 and my bus says 3110.2. So if its bus speed i did over clock to where i wanted but if its the core then i didn't because i have a 2.53 ghz and want to hit 3.0 so did i succeed?

 

OK, sorry if we misunderstood you. If you were saying it was dangerous to use the machine with the lid closed, you are 110% correct.

 

Part of the problem in answering this is that I was not exactly scientific in my temp determinations *before* the mod. So I'll actually need to close it back up to do some fair comparisons.

I did notice that, for some reason, Furmark only hit 90C today (4XAA, 1024x768 windowed). I could have sworn it hit 97C prior to the mod.

 

Oh look, Soviet is typing in class on the first day of school. What a good boy.

Sorry guys, I'll be back to make fun of you all once I get back. I've been really busy with a few clients' computers the past few days and prepping for class and other random stuff.

 

So is that with stock GPU clocks?

Have you tried running it at 8xAA, Extreme burn in mode, and fullscreen?

IIRC, when I run it at those settings, I was getting an equilibrium temperature of like 86C

 

Yeah, Rezigrene was saying that he closes the lid while outputting in HDMI and I was saying that that's not a good thing to do.

 

When using CPU-Z which one do i look to see if i succeeded my overclock. I have a 2.53 and want to go to 3.1 i think i have already succeeded. But do i look at the core speed or do i look at the bus speed. I know its a noobish question but i wanna be positive i am ocing

 

Core speed. It won't show your OC unless your CPU is under load however. Just start up Orthos and see if your OC is stable.

 

What is that MOD and how can I do it? Did it make a difference in your temps? Please make a guide or something I might want to do it too.

 

Check my Sig, did I OC ok? To much? to little? I did hit 97 playing crysis maxed out but it would quickly drop back to about 88 after that.

 

A 1:2.5 Ration for the Core/Shader clocks is more stable, but you're fine.

97C is pretty high though. I don't even hit that in FurMark.

 

ok one thing about the DOX...does the WIN7 link in work for vista 64bit??? srry i dont really wanna go through all 78 pages to find it so im just asking upfront

 

There should be a 64bit Vista option on the site. If not, it ought to work.

You really ought to find a RC7 beta, though.

 

@SACH7002

Switch to 50 posts per page.....its only 16 pages that way....lol

Anyways, the Windows 7 x64 and Vista x64 drivers provided on laptopvideo2go are exactly the same so yes.

@worshipingnow

Like Rezigrene said, a 1 : 2.5 core:shaders ratio would be optimal.

Anyways, if your comp runs well at those overclocks and you're not getting any instability, I'd say that would be fine. Whether you should run your laptop at those overclocked settings all the time, though, is a different story. I'd recommend to only OC your GPU when you're running games or even just the intensive ones.

Its probably fine to leave the OC on your CPU on all of the time as long as your are getting temps (preferably under mid 70C) that aren't too hot since the CPU rarely fails.

@Tallroc

I'd wait a bit till he does some more temp tests. It is still unclear on whether his mod actually made temps better, worse, or didn't change

 

I want to know the temps of the other components after the new fan intake was made.

 

@worshipingnow
I just ordered an X2A from newegg, do you like how it looks, i was not really sure, but i am more of a performance than looks guy, when it comes to laptops.

 

Ack. I totally agree with you then. Like you said, the *top* of the notebook is what gets hot. One time it didn't suspend right when I closed the lid, and within just a few minutes (of doing nothing at all), the lid was feeling quite warm and the fan going full blast.

I'm sincerely sorry for the misunderstanding.

 

HDD temp and THRM stayed exactly the same. ASUS's line about needing the fan to pull air across other components is total BS.

As I stated earlier, the chassis is *not* hermetically sealed, and therefore that tiny fan is generating almost zero airflow all the way over on the other side of the chassis. I'm sorry, but it's just ridiculous. The fan barely generates suction 1/4" in front of its intake - much less 12" away with multiple components and air leaks in between.

Try touching the memory after extended gaming. It's barely warm. Same for the HDD. Even if ASUS were correct, it's the GPU that needs cooling - not an HDD running at 42c. I'd gladly make the trade to better cool my 90c+ component.

 

Very nice, kondor999. That is exactly what I wanted to hear. You will be the first Asus user to receive rep from me. +1 for your ingeniusly primative mod and for proving that Asus is full of themselves once again.

 

Thanks so much. I'm really surprised that ASUS would miss something so obvious. I've never before seen a notebook with a great GPU like this and no intake for its fan. Never mind the fact that the poor little fan is having to cool the CPU as well.

This makes me really worry about the engineering of the rest of the laptop. What else was merely "good enough" instead of "as good as possible"?

Ick.
