An Optimization Guide for the Asus G51

To be honest, I really don't know why your GPU is getting lower temps from the details you have given so far. If I spent the night in bed with your GPU stripped naked of it's copper heatsink, then maybe it would tell me it's secret as to why it's so cool.

 

You do those types of things in bed? God, you're weird.

And the GPU is idling at 46C with an ambient of 71F, so I guess that's where the 2D undervolt helps.

EDIT: Ooh. My CS 1.6 server is back.

 

@Forge

Your temps before, how long did you play Crysis and are those temps through multiple plays or just one?

I mean, temps do fluctuate at times so unless you're getting consistently lower ones for no obvious reason I suppose there is nothing overly weird.

Also, I've seen that you've apparently only played for 30 minutes straight and have paused in between there too so it might be that you just haven't played long enough for the higher temps to kick in yet.

 

Well, the thing is I ran both trials (the one where I maxed at 95 and averaged 93 and the one where I maxed 91 and averaged 89-90) under the same circumstances and conditions. In fact, in the lower-temperature trial I hd actually overclocked.

 

Hmm.......and so did you run Furmark trials? I suppose with those you'd get less variables that may be due to in-game things and get better results.

 

I get about the same temperatures in synthetic benchmarks.

Maybe it was a fluke.

 

Dont think so hahaha.

 

Troll Soviet: Haha, Forge must be overclocking his oven again.

Technical Soviet: I call shenanigans on this. 0deltaT says nothing can run cooler than ambient temperature.

 

That never gets old with you people, does it.

Ha ha.

 

Will make it short:

Win7 = Higher GPU temps while executing nom demanding apps... ( Editing a text, watching a movie, surfing the web )
WinVista = WAY Lower GPU temps ( like 20C ) while executing nom demanding apps...
Example:
Win7 keeps my GPU clocked at 500mhz just to watch a low quality movie, while in Vista I can watch the same movie, using the same player/codec at 275mhz...

Looks like both has the same GPU temps for gaming =)

Ps.: bios changed @ 0xc59c = hex46 ...

 

You can create a profile in nTunes and set it to run when a certain action is met to emulate the downclocking effect.

The performance boost from Windows 7 though still makes it better than Vista, even if the GPU temps dropped to 0C.

 

Off topic: If anyone wants to squeeze a Blu-ray burner in their G51 for cheap, you can buy one here. http://forum.notebookreview.com/showpost.php?p=5223735&postcount=2210. It's a hell of a steal if you ask me.

 

Oh my GOD, that is one hell of a steal.

But that would require BluRay disks to take advantage of, and I don't buy anything I can get for free.

 

Have a shirt.

 

Yar, it be true.

 

what is the clock generator for Q9000? Asus G51VX-A1

 

Regarding the higher temps in W7: Even if you force lower clocks like the 2D ones, you still wouldn't get the lower 2D voltage in nTunes.....so, we're probably stuck with generally higher temps (out of gaming) in W7.

I've noticed that with Extra clocks outside of gaming, my GPU just stays at around 57-58C and the fan doesn't even come on so I suppose its nothing major to worry about.

@putochip0123

Does the PLL I listed not work? I don't think there is any reason why it wouldn't.

 

ICS9LPR604AGLF use this for my Asus G51VX-A1? is it possible to use?

 

I don't know. It works for the Best Buy models so there is no reason why it won't work with the A1s.

Just remember that you'll have to figure out how the clock speed is calculated by yourself since IIRC, the Q9000 probably uses a different multiplier from the P7350.

 

Bluray player ended already, was going to bid on it too =/

 

Kevin_Jack2.0 won the bid. Us Clevo guys had dibs on it way before I brought it over here. Just wait for the seller to put up another one.

 

I'm in love with my new X9100 for the RX05. My framerates in Lock-On doubled (at least) and went from the mid-20's to the low 40's in ARMA II.

Maybe it's the new thermal paste I used, but the thing runs reasonably cool as well - certainly when not gaming. It idles at 26C, but does get pretty damn toasty running at 3.3Ghz - tops out at 70C after extended ARMA II bouts.

I decided to "downclock" the GTX260m to 550mhz and I'll report back what effect that has, since the GPU and CPU are effectively part of the same cooling system in this notebook.

Lastly, after examining the cooling system, I simply can't understand how - with all major heat-generating elements linked via heatpipes to a single fan - it could not be advantageous to improve airflow to the intake of that fan.

Accordingly:


This is definitely ver 1.0. Next, I'll add some filter material and a covering of some sort which will prevent foreign objects from entering the intake. It will also improve the aesthetics a bit (although that seems rather perfectionistic given you'll never see that part of the notebook in operation. Still.).

 

It does prevent Pringles crumbs from being sucked into the fan, haha.

 

This is pretty much the diagram we figures as to why they closed off the vent on the bottom. The GPU is what generates the most heat, the CPU generally stays at a pretty reasonable temp, but opening that vent decreases air flow from the GPU vent, considering the exhaust is right next to where the big CPU vent is located. This stagnates the air flow of the other vents, sacrificing their air flow for the sake of the CPU which arguably doesn't need it nearly as much.

This is what we worked up, but it should be interesting to see if the results offset these assumptions because of your conclusions about the heat-pipes, so run some benchmark games and let us know how it affects your temperatures!

 

Oh, and one last thing. ASUS, IMHO, was foolish not to equip this unit with a fan which is capable of moving more air. Based on my experience with various cooling solutions, it appears that the heatpipe system they designed is actually quite robust. However, the "copper-to-fan" ratio seems wildly unbalanced.

I suspect that the heatpipes are easily able to transport more heat than that small, slow fan can possibly eject.

Given that, in the tight constrains of a notebook this size, you can't increase the physical size of the heat exchange apparatus - it only makes sense to optimize as much as possible in the one area which does not require more space: Fan RPM or efficiency.

Bottom Line: I wish this thing had those new Dyson micromotors and could spin that little fan to within a few RPM of complete flow separation! This is a GAMING notebook. If I'm playing a game, am I really going to care about the noise?

 

I heavily considered what you're saying, but even with the fan at full tilt, there is zero discernible airflow in those areas anyway. The chassis is hardly hermetically sealed. Most of that imagined suction (that would result in air being sucked past the RAM and the HDD) is going to be lost elsewhere, especially when you consider how far away those vents are located from the (tiny, rarely turning) fan itself.

I just don't buy it. It does appear that the "bump" with the chrome ring and fake intake is necessitated primarily by the close proximity of the fan intake to the bottom of the notebook which would otherwise exist. The reason they didn't put a vent there is probably due to the problem I've already experienced - it's now not possible to put the notebook on your lap without interfering with the fan. But that should have been easy to fix with a rigid filter such as what already resides over the RAM. Perhaps I'm totally wrong.

Does anyone have an idea where the THRM (reported in HWMonitor) is located? That's the only way I have to verify temps other than CPU, GPU, and HDD.

In any case, this is all theoretical - and eminently reversible! All I need to do if it causes problems is cover the hole again. If I could do it over again, I would have just drilled holes in the covering. That's probably what I'll end up doing - creating a plastic circular plate with holes, underneath which will be the filter element. Just need to work out how to clean the filter when needed.

But, um, I think I pretty much voided the warranty

 

i dont think you voided your warranty by removing the cover. you can jus buy a new cover. simple as that. as long as you didnt touch the internal components you're all good.

 

Let us know the temps, after ur done with this vent.

 

LOL. Dude, it's not just a cover (I know it looks like one, though). I had to use a Dremel with a cut-off wheel to cut out the circular hole and then sanded it using the Dremel to get a smooth edge. I can't blame you, since you don't have this notebook, and even I couldn't believe the thing was *entirely* cosmetic. Maybe they wanted us to think it was a subwoofer or something?

Also, can someone tell what they're getting on THRM (with HWmonitor) after extended gaming in something both CPU and GPU intensive (such as World in Conflict or ARMA II, or good old Crysis)?

I'm hitting 71C. Yikes. May have f'ed up here, guys. Then again, with the X9100 and the OC'ed GTX260m - maybe it's normal?

Thanks!

 

dude you don't get me. the backplate you made a hole in doesnt void your warranty. removing the cpu/gpu does void your warranty because there is a sticker that says warranty voided if removed on the cpu heatsink.

if you are getting 71C max for the GPU then congrats, you have the lowest temp of all g51vx users. if thats your cpu max temp i would suggest undervolting.

 

If you check out the previous paragraph, you'll note that I was talking about the THRM value when I referred to my 71c reading in HWMonitor. The THRM is typically located somewhere in the chassis (and I've been asking exactly where on the G51).

If you look at my sig, you'll see I'm running an X9100 anyway - one of the reasons I didn't care about cutting a hole in the chassis. Still, I'm sorry but I simply can't believe that ASUS would honor a warranty claim on a notebook with a big hole that some idiot (me) put in the bottom LOL.

BTW, I can't see how ASUS could even tell if you removed and then replaced the little yellow sticker on one of the CPU screws. It was really easy to peel up and stick back down. No way could you tell anything was done.

Hopefully none of this matters since I've never had a notebook break...under warranty LOL.

 

What clocks do you guys think are better, 605/950/1512 or 625/925/1515?

 

Um, I guess that's a joke? Why not just run 3Dmark. In any case, perhaps you're highlighting our penchant for splitting hairs, as those 2 clock combos are nearly identical, with the possible exception of the 20mhz difference on the GPU core. But the difference between 1515 and 1512 on the shader clock? Why even make them different?

Anyway, I'm assuming it's a joke of some kind.

 

cool story bro

 

625/925/1515 is faster. you wont get any noticeable increase from the memory clock (apart from heat lol). you will get more performance from the core and shader clocks.

@kondor999

my apologies.

 

If the sticker is in one piece and attached, your warranty is still in effect.

Unlike mine. Poor guy got ripped in two, after at least ten disassemblies with no tears. Stupid finger spaz.

 

Didn't I just yell at you about this in the other thread?

http://forum.notebookreview.com/showpost.php?p=5225782&postcount=2669

 

@kondor999

So....what temps are you getting now?

I mean the CPU, GPU, and HDD temps.....kinda interested in what the removal of that vent thing actually does since noone has really done it and reported new temps yet.

 

You might have, I had forgotten where I had posted what.

The ratio is 1:2.5, right? Or am I thinking of something else?

 

nou

(secret ten characters)

 

I'm collating the data now so it's accurate and therefore useful for everyone. BTW, thanks so much for the careful work you've done thus far in illuminating the G51 for all of us.

I foolishly changed 2 variables at once - going from the P7350 to the X9100, and then making that hole rather impulsively. Makes it hard as Hell to compare before/after. I wish I had done some temp testing with that hole covered!

One thing: can you tell me what the rest of you guys get on THRM (using HWMonitor) after extended gaming?

 

Not with that attitude I'm not.

 

I want to flash my bios to be .90/.75/.75/.70
but apparently you can't do the 2D @ 0.70v unless you use the table editor or something.

I would use the one that Tev supplied on the first post but it appears that his is more out of date that mine. Does that make a difference.

I have a bios from 06/02/09. version 62.92.83.00.12

I was wondering if someone could edit my current bios to have those voltages for me?

 

Again, I sincerely hope you're joking. In any case, I'm sure I'll get by somehow. Hey, it's not my fault you posted a question which was, well, shall we say...potentially humorous. Um, sorry your feelings got hurt due to my attempt at obtaining...clarification.

Back to business. Guys, I think I've hit the wall as far as how much I'm willing to risk this thing. Running Crysis tonight, the GPU temp (per HWM) hit 97C max. Now that shi* is *hot*. Definitely the hottest I've ever seen *any* component run (and survive). The THRM is hitting 73C as well - which also seems somewhat objectionable (although, deprived of comparative data, it's difficult to know).

I'm using the settings listed in my sig.

This is an interesting notebook. I've not had prior experience with a gaming notebook where the heat exchanger was shared between the CPU and GPU in this manner. There is (obviously) a lot of interdependency between the CPU and GPU in terms of heat production/retention/rejection - with the GPU clearly coming off the worse.

Suffice to say, I'm seeing about 5-7c higher GPU temps with the X9100 running at 3.3GHz. Next, I'll re-test at a more sane 3.06 and see if some sort of balance can be obtained.

Thus far, my gut tells me my hole-creating experiment is a bust. This fan doesn't move enough air to make it matter. However, I bet a cooler blowing right in there might help!

*OH NO* - another permutation. Jesus - this is gonna take forever to analyze. LOL

 

Cool story, bro.

 

I think I failed to update vga bios and now it counldn't shown anything on the display, How can I restore bios? Is vga bios share with the mainboard bios or it has it own bios? thank you.

 

GPU BIOS is different from the main BIOS.

To reflash, just insert your USB boot drive, wait about thirty seconds, type in "nvflash OLDBIOS.ROM" (Without quotations, and where OLDBIOS.ROM is the name of your old BIOS), and hit enter. After another ten seconds, hit the "y" key on your keyboard.

After you reflash, come back here so Soviet can laugh at you.

 

Because he's definitely going to.

"hur hur hur god you're like an alienware kid." -Soviet Sunrise

 

still not work, I took usb off and I want to see it really boot into HD or not answer was not. It stucked somewhere any solution?

 

Actually, I'm having some second thoughts on the viability of running 2D at 0.70v. Will post more later today.

So....it looks like we're probably better off not cutting out the vent thing then.

Remember that after tying in "nvflash OLDBIOS.rom" and pressing enter, you have to press "y" after waiting 10 seconds or so.
