An Optimization Guide for the Asus G51

When I boot up my computer, I will waiting for my Usb to boot up but nothing access to my Usb. any suggestion?

 

Hey guys, I've been using the 0.70v 2D undervolt for a while now and I have noticed a potential issue.

It seems that alot of time, the GPU would just stay at "Extra" voltage and clock levels even while idling for like an hour. I'd still see 2D clocks at times but it has become fairly rare. I think that the voltage may be too low so 2D might not be working too well at 0.70v.

I have just flashed my GPU back to 0.75v 2D and at idle, its running perfectly at 2D clocks.

Just wondering whether other people running 2D at 0.70v has noticed this issue. To check which clocks you're running at, run GPU-Z and go to the Sensors tab. It will list the GPU Core Clock and GPU Memory Clock in real time there. 2D should be 200/120 while in 3D its 500/799

Go to the motherboard, go to boot priority, and under HDD priority, change the USB's priority above the HDD.

 

I think I lost my computer already. Nothing shown on the display or boot into any devices. But it's ok, I'll send it back for repair. Thanks for you guys helping me.

 

Where are you sending it to?

BIOS mods aren't covered by ASUS.

 

I'll tell you later it can be fixed it or not. soon

 

Thanks for the heads up.

however,

I undervolted my CPU (Q9000) to show on CPUz as 1.050v.
And my GPU is now flashed to .90/.75/.75/.75

I ran Orthos for 30min, with no errors and lost about 10c from before.
However after running 3dmark06, I have now lost about 300 points.

Am I undervolting too much or am I doing something wrong.

 

What are the clocks you're running on your 260, and what are your max temps?

Personally I think you're fine; 3DMark isn't necessarily a predictor of in-game performance. Even with a loss of 3DMArks you're still going to crush any game you want to play while staying cooler.

 

my gpu at stock clocks (500core/799mem/1250shad)
and max temp for CPU is 68/69.
GPU is 90. (I think it went down by 1-3 degrees C)

I just thought that, when you undervolt, it's not supposed to impact performance at all, only overclocking ability.


Testing with only GPU undervolted, my 3dmarks go backup 300 points.

but you're right.
if i'm not doing anything wrong. I'm just going to keep it at 1.163v (CPUZ coreVID 1.050v).

EDIT:
Oh one question though.
Should my multipliers with CrystalCPUID be Max7.5x/Mid7.0x/Min6.0x ? And then what I want to undervolt (1.163v VID) for all of them.
Cuz originally it was 7.5x for all

 

tumman007. You can always just force flash your system BIOS and GPU BIOS back to factory default. If Asus finds out that you have altered your GPU BIOS, then your warranty is nulled.

As for Forge and Rezigrene, don't listen to those two blockheads.

 

Multipliers are based on load. They'll drop on their own.

 

I seem to have no issues.

Right now I'm at a steady 200/120 setting.

 

@Tevas

hmmm I had this issue in Win7, but it was more Software related than Voltage thing =P

Steady 200/120 using WinVista now, just like Forge..

Ps.: No overclocking here, neither CPU, only undervoltage =P

 

When undervolting, what test are you suppose to do on Orthos, Blend, small FFts, or what? does it matter?

 

Orthos will test your CPU stability... Just go Blend test for half a hour... It does matter alot =D Unstable CPU can crash your programs and stuffs you dont wanna happening in your system...

But you should try some heavy gaming too, like Crysis...

 

This is wierd, instead of cpu-z showing the undervolted voltage it changes from 1.113 to 1.038 to 1.250. It was showing the underclocked voltages before, dont know why its doing this now. It cant be that ive undervolted it too much cuz ive only gone down to 1.188v so far.

 

Are you using CPU-Z 1.51? If dont, use it =D

 

Yes i am using 1.51. Like i said, it was working completely fine before. it was showing the underclocked voltage and everything but then after a couple voltage changes the Core VID now fluctuates between 1.250, 1.038, and 1.113. It shows those voltages even after ive restarted my laptop and havent turned on crystal cpuid yet. i also noticed that it shows 1.250v when it shows the multiplier at 7.5 and it shows 1.113 and 1.038 when multiplier is at 6 but i havent changed any of the multipliers. all three are at 7.5 in crystal cpuid.

 

I'm working on using nTools to overclock the gpu, but i keep getting an error msg saying the changes made were invalid and will not be applied. plz help me with this. I followed all the other instructions perfectly.

 

Anyways....Crystal CPUID's undervolting may be a bit sketchy in its "stickiness." I've always wanted to look into it but I've been really lazy with school coming up.......

Also, I've flashed back to 0.70v to just check it out a bit more.

Furthermore, I've discovered that outputting via HDMI to a TV running a resolution of 1080p automatically forces your GPU into "Extra" level clocks and voltages even at idle.

@accuracy

3DMark06 can vary by a couple hundred of points just from random differences even with no differences made to the hardware via overclocking or undervolting.

Don't worry about it.

And in regards to BIOS version, the version that I provided should be fine. Yours just is recorded as being newer probably because the A1 was released after the RX05. The GPU vBIOS should be exactly the same between the various G51 models.

@tumman007

I think it can probably be fixed pretty easily if you just tell us a bit mopre details.

@rellim

What changes did you make when it gave you that error?

 

This is what I have done.
-I created Usb drive with system file nvflash and rom within.
-boot sysytem with usb first priority.
-system boot into Usb then I typed nvflash newrom.rom then y
-wait about 2 hours and it struck the line store image, It must be something wrong right? 2 hours too long?
- I decided to reboot system then only blank screen shown up nothing more.
- My Usb drive if anything access to it, the blue light will blink on my usb but no light no blink.
- I took usb off and boot to see if it the system can boot into HDD or not, No HDD light not blink no operation from HDD at all.
- I put bootable cd but result was the same, system not read cd only just dianostic.

That's why blind access not work at all. Do you have any idea to bypass VGA bios checked? or any solution before I take it to Asus service? Thxs man.

br,

 

Do the fans even spin when to hit the power button?

On a side note, the Memory clock on your 260 is really, really high. Like, higher than it needs to be.

Especially since the Memory clock doesn't add enough performance to outweight the heat it creates. That's why I dropped my memory clocks from 950 to 900 and raised the core/shader speeds.

 

when I hit the power, fan spin and 3 lights on the bar comes up, cd checked but not bootable, keyboard work ctl alt delete also work when I press it.

 

How do you know if CtrlAltDel work or the CD Drive can't be used if nothing comes up on your screen?

 

I knew from the light, it blinked and I heard dvd-drive checked it everytimes I press ctl alt del.

 

Did you name the BIOS file on your USB stick anything?

 

just default OLDBIOS.ROM and NEWBIOS.ROM.

 

You're supposed to be using nvflash oldbios.rom, not nvflash newbios.rom. The new BIOS flie is the one that isn't working; why are you trying to flash it?

 

That's what I've done at the first times. Now I want to flash it back to oldbios.rom but system not boot into any usb cd nor hdd anymore so that's the problem I face it now.

 

I got that, but in that little bit I put in bold from your post you said you used "nvflash newbios.rom." You don't want to do that if your BIOS names are the defaults and you want to use your old BIOS. You want to use "nvflash oldbios.rom."

 

So you've tried blind-flashing and still no luck? So, you inserted the USB, booted up the computer, waited thirty seconds, typed in "nvflash oldbios.rom", hit enter, waited fifteen seconds, hit "y", and then it still stays stuck?

And I find it astounding that Soviet has not laughed yet. He must be mellowing out.

 

No, I just had my stomach share of Jack at a friend's birthday.

Later today, I will be trying out the latest notebook driver 186.42 WHQL. From my observation, I expect to get a little bit more kick out of them coming from 186.03 WHQL. Over the weekend, I will be making a homemade thermal paste in which I believe will cool better than ICD7 and will apply easier like MX-2. Details will be kept under wraps until I debut my concoction on Monday.

The good thing that I'm happy about is that I was able to get all of the classes I wanted this semester despite all the budget cuts in the CSU. Most of my classes will be in the computer lab so I will have the luxury of playing games, browsing, sleeping, not paying attention, and bumming around on the computer during class while maintaining my near straight A record.

 

Latest data dump:

X9100 CPU
1.350v@3059Mhz - max 73c (core1)/68c (core2) with Orthos
1.300v@3059 - max 67/63 with Orthos
1.250v@3059 - max 67/62
1.238v - 67/63
1.225v - fail
1.200v - fail

RESULT:
Oddly, voltages below 1.300v don't seem to buy much lower heat production on the X9100. Or the fan is programmed to simply not turn as fast and is thermostatically regulating the temp. to that level.
====================================
GPU testing (CPU at low speed, GPU overclocked):

Furmark 640x480 windowed 8XMSAA
CPU restricted to 1.6 and 1.163v = 50c/47c max
GPU max (550/800/1375) = 96+ max (test shut down before it got any higher, but no problems noted)

RESULT:
CPU speed/voltage = NO APPARENT EFFECT on max GPU temp

Again, I could visually verify that the fan just does not turn very fast and is nearly silent. This seems to be the primary defect. If the fan turned faster, I am confident that cooling performance could improve substantially. My next experiment will be to aggressively introduce cooler air directly into the fan intake.
====================================
GPU Test 2 (CPU at high speed, GPU stock):

Furmark 640x480 windowed 8XMSAA
CPU [email protected] fixed = 50c/49c
GPU max (500/800/1250) = 91c

RESULT:
GPU temp seems completely independent of CPU temp/speed. Overclocking of GPU to GTX260m "stock" (Nvidia defined) levels (550/800/1375) results in overly high GPU temps of 97c and more. Leaving the ASUS values (500/800/1250) gives 91c.

LESSON:
Overclocking GPU even by small amounts seems inadvisable currently. ASUS appears to have known what it was doing when it underclocked the GTX260m.

 

I'll just leave this here.

 

I this a GTX260m BIOS for NiBitor? If so, what are the relevant values contained therein? Sorry if it would be obvious if I read through past posts, but time is limited atm.

Obviously, given the data I've collected, my primary concern is keeping this 260m cool. What I'd really love is voltages that allowed a 600-799-1500 overclock - but I'm probably dreaming that anything below the GPU's stock voltage would allow that.

 

Has anyone figured out how to use Crystalcpuid to increase the (unlocked) multiplier of the X9100 (or other Extreme series CPU)?

I know I need to edit the .ini file, but I don't know what values to change. I'd rather change the multiplier than continue to o/c the FSB as I've been doing, since I consider the CPU itself to be the most robust part of the system.

I was able to hit 3.53Ghz BTW via FSB increases before I reached the limit at 3.62. I have a feeling this little hot-rod could hit 3.6 if I could play with the multiplier.

 

Blind-flashing may be work for some system like PC but on G51 I could say not working at all. The system will initial up with first checking was VGA and if VGA not there or not found, it will wait up not let you pass this step easily. So beware of it. I don't care much now because my G51 back to live again after took VGA card out and gave bios chip Yes!! you right!!! bios chip I took it from 260M then gave it my friend to re-flash it on the machine which can read-write bios. It bring back my smile again. By the way many thx to your guys even if not working but I do feel appriciate for that. Thxs

 

So.....what happens is that if at POST the vBIOS doesn't check out, the machine just gets stuck there and you can't do anything? Weird......

 

Yes, can't do anything. I hope no one will get struck like me, trust me it's somekind of nightmare.

Where the dead people go? only one can tell was just dead people. I'm the man who came back to tell what out there!!! 5555 but I still trying to flash vbios one more time it worth to do so.

 

Looks like the laugh is on you guys for not being able to solve tmman007's problem, haha.

 

My G51VX-X1A just got here and I <3333 it. I shall be having a fun day. Just popped open HW monitor, and have 47C as an idling GPU temp. Will test the higher end after I finish removing a bit of bloatware/updating drivers

 

Element I purchased that same version from newegg. Should be here on monday. How is it, and do you know if tev's opt guide will work on this version. Like will the setfsb pll be the same as the BB version

 

I haven't tested any of Tev's guide yet. I got it used for 800$ (guy had it in hand for a week, never OC'd, never gamed etc) so I've spent the last while reinstalling everything to factory settings. It still has that new laptop smell

here is a 3DMark06 score @ standard ORB reso. Will post more once I get all the new drivers installed.

 

One thing I find impressive about this notebook is that the underside temperature does not appreciably increase (subjectively - which is all that matters in this case) regardless of internal temps.

That's really what made me keep the notebook: unlike my M1730, it's actually useable while on your...lap. That's become quite unusual among gaming notebooks.

 

I started to OC, Undervolt etc with my G51, but then I thought "this is a very powerful machine, I shouldn't be doing this!".
Since then my temps haven't gone over 88C. I play Crysis (Very High, 4x AA), Gears of War, Mirror's Edge, Far Cry 2, all on the highest settings with no problem.

I use HWMonitor and a laptop cooling base while gaming.

 

I just hit 99C playing bioshock for 15 minutes. I was at highest settings and 1920x1080 res...but those temps scare me :S

 

You're having a barbecue and you didn't invite me, EIement? I see how it is.

 

I don't want to have a barbeque.

 

My scores after updating drivers and OCing the cpu to 2.8ghz.




Thats with stock GPU clocks. I broke 10k so I'm satisfied. The heat is still troubling though :\

 

Still gotcha beat

Let me do some new benchmarks.

 

You know what to do, soldier. Open her up and replace the thermal paste.
