An Optimization Guide for the Asus G51

So I'm thinking of picking up a T9800(you guys are driving me upgrade-crazy with your benchmarks...;P).

Whats the difference between the T9800 and the X9100 than make such an insanely huge price difference? As far as I can tell, the X9100 is just clocked like .13Ghz faster...

 

The X9100 is 5% faster at factory clocks. That's pretty much it.

 

yup, definitely NOT worth paying three times the price...thanks!

Looks like I'm going to hold off on the Intel SSD and get the T9800...

 

Plus the X9100 runs hotter than T-series.

What's the maximum multiplier of a T9800?

 

my little guy says 11.0x, i think thats correct!

 

Indeed, that is correct.

 

I have 2 choices of CPU for the G51.

Which one should I take, considering performance and heat/ battery?

1. Intel T9600 2.8GHz OEM - $240
2. Intel P9600 2.66GHz OEM (warranty 12M) - $200

 

Ive been using the t9800,(close to the T9600) and it has worked flawlessly for me. I can get about 2+ hours of battery life with the power saver mode. I'm always plugged in though, so not really an issue for me.

I saw a decrease in temps with my T9800, from the P7350.

Both of those CPU's are excellent choices, as they both have 6mb of L2 Cache. It really is either or. I threw down 300 for my T9800, so 200 for that T9600 is an awesome price.

 

@a3rox

It really would be up to your preference.....I can see the arguments for either of them

 

I'd take the T9600; higher overclocks for the win.

 

In the battle for a cooler computer, a P-series is always nice.

Kind of funny, since I have a X9100, but yah.

 

Oh, look at me. I'm Forge and I have an X9100.

Heh. Just joking.

Maybe.

 

LOL

I remember when I had a P7350...

 

Now to read "Oh, look at me, I'm Forge, and I have an X9100.

Which I keep undervolted.
And underclocked.
And I practically never use its full power."

 

"Oh look at me, I'm Forge, and (insert mean comment here)."

 

Go on, I can take it.

 

Oh, look at me. I'm Forge, and no one has seen my true power level.

 

That's not a mean comment you nincompoop.

 

Yeah, well.



You're a doodlehead.

 

The hell's a doodlehead. I demand pictures.

 

What the hell's a nincompoop?

 

I don't know. You tell me.


Anyway, I've noticed that at stock GPU clocks, my max temperatures aren't really affected by CPU undervolt/underclock.

At stock 1.350 voltage and at 1.163 I maxed out at 87C.

Damn fan doesn't kick in until I hit 87. With the fan on I don't go above the temperature that it's at when it activates.

 

Lucky you. I don't think my fan hits max speed until about 94C.

Which I only ever hit on FurCube, so it's whatever.

 

It doesn't hit full speed. It just hits the second-fastest speed and that's usually enough. I don't hit max until nineties.

 

Ah, gotcha. I only noticed three speeds, idle, 60ish, and 94ish.

 

Wow, I go for a little troll stroll to the Alienware forum for a few minutes, and I come back seeing Rezigrene as the last poster in half the threads on the front page, haha.

Atleast your fan will be sucking up less dust at a lower speed.

Yeah! 2,000 posts and Notebook Virtuoso!

 

Ha, Alienware.

Dude, you're getting a D-ell!

 

Took RivaTuner 2.24B out for a spin with Dox 185.85.

Did nothing. Uninstalling and switching back to nTools.

 

Tis a shame that RivaTuner still doesn't work.

I remember reading some places that with RivaTuner you can actually undervolt your GPU software wise after a bit of tweaking. Not really useful for me but it might allow us to just go to something like 0.92v and actually overclock a little bit while still get lower temps

 

I remember when I first got the G51 and RivaTuner didnt work, I thought my days of OC'ing were over. Then somehow I found nTools! Ah, my life took such a turn for the better

I remember in early 2007, my friend had an alienware with dual 7950 GT's or something like that in Sli. It was a 4500 dollar machine. clocked with the fastest intel processor at the time: 2.33Ghz!

less than two years later, i have a $999 dollar rig that smokes that thing. hilarious how technology works

 

Does anyone know a link to a good CPU replacement guide?
Or nice enough to post a guide for me ?
I've never replaced a CPU for a laptop..
Desktops. I can do it with my eyes closed xP
I'm thinking about getting a p9700..

 

I believe it should be basically the same. Just remove heat sink, get the old one out, put the new one in, and then put the thermal paste on and afterwards, the heat sink.

 

Yea, just wondering if anyone posted a guide specifically for G51

 

Just to let you guys know, I have attached new vBIOSes with lower voltages to the first post. One has 3D/Thrtl/2D all at 0.75v which is all but guaranteed to work on my system at least. The other also has 2D dropped down to 0.70v. I'm still not quite positive that it is fine but it seems so.

I still have not tried underclocking 2D clocks to get even lower idle temps but I suppose that is the next step/

General purpose guides should do well since changing the CPU is pretty much the same for most laptops.



Finally, this is my 1,000th POST !!!!!!!!

 

Congrats, TevashSzat! I think Forge has also confirmed that 0.7v works well at 2D. I'm not too sure though. My inbox was filling up with PM's after I released that GPU BIOS so I can't remember who tried it and got it to work or not.

 

How you guys hex edited the vBios? I tried asking google, but got lots of weird answers, then I tried comparing the two BIOS ( NEWBIOS.ROM with OLDBIOS.ROM ) and found only single bytes changes all over the files, no unique pattern or anything...

As you may know, my GPU is crappy and I cant run 0.9V, but I would like to try 0.95V/0.75V/0.75V/0.7V =) So, if any of you could point me to a tutorial to Hex Edit vBios or something, i appreciate...

or you guys are just Reverse engineering NiBiTor to allow lower voltages? ( hmmm should I try it ? xD )

Thanks again =)

 

I guess i just found it..

There was already a function in NiBiTor, only found it after opening it at Olly =X
LoL.. Im gonna play with it a bit more... =)

 

Don't hurt yourself now.

 

Very good !You're the one!Thank you very much!

 

@Sirhase

I have attached a 0.95/0.75/0.75/0.70 vBIOS to this post if you have trouble with making it work on yours.

 

Just so you guys know, with assistance from Soviet, I've tested out two different vBIOS where the only setting changed was the extra voltage. So, there was a .92/.85/.85/.85 and a .93/.85/.85/.85.

There was essentially no overclocking gain over a vBIOS with .90 Extra voltage.

I will confirm, after flashing with a different vBIOS that .95/.75/.75/.70 works for me.

 

@Tevas
Hey man, love you =)

I fell bad always asking for help and not able to give anything in return other than "Thanks =P".. So Im gonna atleast give some results and some thinking:

To start I am using the vBIOS 0.95V/0.75V/0.75V/0.7V.. What are the IDLE Temps difference between this and the Stock voltages? For me using Win7, none...

But how? I got some theory's, I think its the Windows7 thing, when I said I had epic good low temps before, it was the time I was using Windows Vista, not sure yet if its the heat problem here, but I see some Core Clocks changes while my PC is Idle in Win7, it jumps to 500/800, then go back to 200/120... I once got 70C in GPU while typing in OpenOffice...

So, I guess changing the 2D Voltage is not gonna do much while in Win7, only if you change the Extra voltage, that actually gave me epic temps before, but unfortunately, its unstable... I think Im gonna try later a 0.9V voltage with a underclocked vBIOS, what you guys think?

Ps.: While typing this text, I got a max temp of 65C, and rising now...
Tomorrow Im installing RAID 0 and will go back to Windows Vista, then I can see if its a Win7 thing or not =)

 

If your factory clocks of 500/1250/800 fails to remain stable at 0.9v, you should stay with 0.95v. I shall reitterate that you have a Friday night card. Your card may see subtle changes from a decreased idle voltage, or it may not. Remember that the second part of lowering idle temps is to underclock alongside undervolt.

I gave a long hard thought about your post earlier and I have decided that I will not teach you how to hand code the GPU BIOS. I am in no position nor am I willing to pass on that information yet.

 

hmm Im not sure what you mean by hand code the BIOS, but if its about changing the voltage of it I guess its ok.. Im using a BIOS I customized myself, with 2D at 0.7V and is stable so far, but temps still the same as before...

But the thing is, the GPU clocks dont stay at the 2D clocks most of the time here, so it make sense why I have no temp decrease, I guess Win7 has lots of fancy stuffs that keep asking more resource from the GPU, thus making it heat more... When I watch a movie for example, it changes the GPU clock to 500/800 -_-

 

The BIOS you downloaded from TevashSzat's link was already customized.

Yes, that is normal. The GPU takes over video rendering, which is far more effective than letting the CPU handle it. Whenever I watch my bootleg shows like Futurama, my GPU upclocks to 400/800/300 and even further to my max clocks when watching Blu-ray quality movies.

 

My computer seems to run rooler than before in Crysis.

Before (A day or so after applying MX-3 to the CPU and GPU) I had my CPU at 1.250v and 3.06 GHz, and GPU at 550/1375/925. After about half an hour of play, I maxed at 95, though my "usual" high temperature was 93C. Ambient was about 75F.


Today I did another 30-minute session, same map, same game settings. CPU was at the same level as before, but my GPU was actually overclocked farther to 580/1450/900. Also, I had applied a .95/.75/.75/.70 vBIOS.
After gaming, I checked my max temperature: 91. And the max was only reached during a couple of 1-second spikes. I was hovering around the 89-90 range. Ambient was 72F.

I'm including my GPU-Z log for giggles. Lower voltages on the non-extra settings shouldn't affect stuff during a game, right?

 

I'm going to make you paranoid and say yes, lower non-extra settings will affect stuff during a game.

 

Well, I remember you saying it wouldn't, so the jokes on you. I'm sort of thinking out loud/with my fingers.

But I really don't know what's giving me these lower temperatures. I mean, I'm not complaining, but I do want to know what I did.

And the only significant thing I remember doing is flashing a new vBIOS

 

If you're running games, your GPU should be running at max clocks for the entire duration. Only if you are running the new 190 drivers that have adaptive power management will you see lower temperatures periodically during less intensive games. However, you are running Dox 185.85 so I don't know what to say. I'd shut my pie hole if I got lower temps and don't know why they are lower.

 

I'd like to figure it out so, you know, I could share. I'm an altruist.

Kind of.
