GT627 Overclocking Question (and 9800GS to GTS)

I have a few questions for those GT627 owners since I'm buying one soon (I was ordering a FW and then cancelled since the price was the same and I could get a 9800GS).

First of all, is the Turbo button really functional? I mean,you know every processor can have different OC limits, so, does it OC your processor to a "standard" speed (equal on all 627) or if you get a better processor will it OC more than, say, your brother's 627 with equal CPU?

Secondly, is it really playable for hours with the turbo function activated because of the heat? I mean, can you just push the turbo button when gaming and game like 3-4 hours straight without the machine hanging up because of extra heat?

And finally, on the Asus subforum there's a guide on how to mod (BIOS) the 9800GS to a 9800GTS since they're the same cards. It will work for some and won't for others because these are nvidia chips that failed the GTS standards but meets the GS standars, or chips that didn't sell when nvidia moved to 55nm (so they're basically GTS downclocked and undervolted -that's why you need the bios mod-). Has anyone tried this mod? and do you think it will work on an 627 since it draws more voltage, so it will be even hotter in there? If anyone here tried this on their 627 please comment!

Thanks!!

 

i can try answering a couple i dont have gt627 but 725 with similler button

it will over clock ur procssor to a stander limit via turobo button like all GT725 go up to smiller 2.93. if u change the procssor and the turbo button read it u should be able to oc it more than other users but dont quote me on that.
if the turbo buton button doest work with diffirent processor u can still over clock it in bios

i have used turbo button a few time for hours and the machine did nt heat up that much atleast i did nt notice it at all i was playing crysis and doing some benchmarks

 

This particular question here you should ask in the Asus Forum they should be able to give you a direct answer for that, good luck to you.

 

Thanks to both of you!

I just asked here because obviously Asus manages heat better because of bigger case (G50 vs GT627 for example) and thus, they didn't have any problems. I just wanted to know here.

It seems weird to me no one has already modded their 9800GS to a GTS since there are good improvements!

Anyways, thanks!! =D

 

That is SOOOOOOO WRONG!

Heat management:
ASUS 3 points (Because gateway gets only 1 points)
MSI 8 points

 

great question. i'm wondering the same thing. has anyone tried to flash the bios to convert the GS to a GTS?

 

This will give you a good indication of how great this machine really is...

Everest Performance Report

I've been running on Turbo for hours playing Crysis, GTAIV and several other games without any heat problems.

The MSI GT627 has a very efficient heat sink!

 

i agree with Tunay this notebooks should have better heat management then the Asus

 

Oh! thank you very much! I really thought the MSI, being so sleek and specced up like a 17'' laptop would not be so good at heat management. I've been proved wrong =P

Anyways, thanks for the info everybody! and check out that Asus topic because modding your 9800GS to a GTS is reeeally simple and if you got a nice card, you got great improvements too! it raises the voltage though so don't even bother gaming without ac -who does anyways right?-

Thanks!!

 

being a owner of gt725 i can tell you about heat problem. what heat problem ???

nosie ???

 

How does one tell whether one's 9800m GS is a modifiable version?

 

I tried to overclock but I couldn't raise the voltage with nibitor for some reason. Couldn't use the Asus bios either since it's made for their board and not the MSI one.

 

You need the 9800m GTS bios only, this is card-related and it has nothing to do with asus I think, it's not the mobo bios but the 3d bios.

And you don't know if your card is "moddable", you just try it, if you get errors or glithces you flash it again with the original bios.

Everything is quite well explained:

http://forum.notebookreview.com/showthread.php?t=357807&highlight=9800m+gs+flash

 

l tried doing that. Using the bios posted there it says I have the incorrect board. I tried using nvflash to extract my bios and edit it to GTS settings but it wouldn't let me modify the voltage past 1.06.

 

Heat:
I'm waiting for full summer BEFORE I make ANY thermal management commentaries.

BIOS modding can't help you with that but best bet may be to ask on the ASUS 9800M GS thread, or maybe start a brand new brand agnostic thread in the appropriate forum as undoubtedly other notebooks will show up the the 9800M GS as well... (or nVidia re-branded/named parts)

 

So there's no way of telling whether your 9800m GS is modifiable? I guess I am back to waiting for the GT628 then : /

 

I managed to break the 10K point barrier under 3DMark06 free version.

(CPU in turbo mode @ 2.9ghz, GPU with DOX 182.05 OP and 560/800/1400)

I haven't touch the BIOS yet.



Not bad huh?

 

Hey RayanMX, I've noticed that all your benchmarks have been higher than mine on my 627. I'm running Vista Home Premium 64 with the 179 nvidia drivers. I see you have DOX driver but when I had installed those I didn't see a rise in FPS and the heat seemed to kick up. I guess what I'm asking is what is it you did to get the scores you have? Can either post here(sorry I know this is about oc'ing the graphics card) or send me a PM please.

As for OC'ing has anyone else tried to do it with the bios update?

 

No problem, well basically I installed DOX driver but in my case I had three installation options, Quality (slow), Balanced (intermediate) and Performance (fastest). At first I installed the Quality one and my marks got lowered by 700 points or so. The I tried the Performance one and my score returned to about the same I was having with the 178 driver.

Then I decided to go ahead and overclock the card with NVidia System Tools.

I played a lot with the settings and as you noticed I managed to get upto 10K points with 3Dmark06, but I was using a lower resolution by mistake, then I raised the resolution to the default one 1280x1024 and my score totaled 9728 points.

My overclock settings are:

620/850/1450

I monitor the card throughout the benchmarking process and the hottest peak reached about 64C.

DOX 182.05 are famous because it allows higher overclocking than others and more stability.

You should try it some time.

I'm still deciding if I want to upgrade the BIOS to GTS.

Cheers!
RayanMX

 

Thanks, i'll try that out. I've done overclocking of cpu's on desktops but when it comes to graphics cards I always had a card that made me more than happy so never bothered with oc'ing. Even with the 9800 gs at stock I'm happy but for some reason since getting this laptop(my first) i've gotten a little obsessed with numbers.

 

Yeah I agree, I know that feeling... I'm very satisfied with the stock settings, but for some reason I like pushing it to it's limits!


On this video you'll see a 3DMark06 test run. A bit lengthy but at the end you'll see the 3D Score.

 

58 degrees.. is that the max? wow!

Would you recommend buying the GT627 now and overclock the video card or wait for the GT628?

Also, where can I find more information, or better yet a step by step guide for dummies, on over clocking the 9800m GS?

 

Nice step of nVidia again. Both GF9800GS and GTS 160 are using same core - G94M. Witch meas that there is no difference between these cards. The only difference is that:
GF9800GS
Core Speed - 530 MHz
Shader Speed - 1325 MHz
Memory Speed - 800 MHz
against GTS 160
Core Speed - 600 MHz
Shader Speed - 1500 MHz
Memory Speed - 800 MHz
As I've read I know that G94M core can easily be overclocked to the speeds of GF9800GTS, which are the same of GTS 160, so considering the price I sugest to you to buy now GT627 and overclock it to GF9800GTS. You will see no defference between cards. Don't be afraid for the temperature also, because the termal design is calculated for GF9800GTS. So save money and OVERCLOCK
Also you can show some bravery and overclock it more

 

Nah... I recommend you to wait for the GT9000

Just kidding, don't be fooled by the never-ending-story of technology upgrade paths...

You know? if you wait for the next technology, then by the time you commit the purchase, there's already something newer down the road.

I think Genna explained it all already....

 

Interesting.. so does that mean one can overclock the 9800m GS and have pretty much the same performance as an overclocked GT 160m?

 

As I said, both cards use same GPU - G94M. I think that nVidia have GPUs left on store and they want to rid of them. This trick they are doing is not for the first time and it won't be their last. About overclocking - you will be not able to overclock it much more than you can overclock 9800M-GS (same core ), ofcourse it depends here how much luck you have and what core you'll get. Will it be more overclockable or not. GT 160 are tested G94M cores that can be clocked to these frequences at nVidia laboratories. Also there is one more thing, since nVidia followed AMD/ATi step and moved to 55nm production process they might produce some G94M cores on that process, wich will garantee more overclock. That's it - hope to be helpfull.

 

-the 160m gts uses G94b core while 9800 gts and gs both use G94 (notice the " b")
-I think sb said in a post that the gt628 has delayed

 

@ saeedN
He he, nice remark. Thanks. But do you know what the difference is between "a" and "b"? Version "a" is 65nm and "b" is 55nm. This is the only difference, there is no difference inside the core. Which means that - new production process allows nVidia to make more chips that can reach 600MHz frequences than G94 "a". Also it means better higher OC of "b" revision, but since this is card is for laptop and heat is very important here, I don't think that is good to push the core to its limits. Because I know that most of G94 "a" can make core clock of 600MHz without any issues is good to save some money and go with GF9800M GS. Arrrrh if I only can find one... I'll show you what I mean.

 

yawp, Im the one that made the thread about the MSI GT628 being delayed. I spoke to them over the phone and emailed them. Same response, its not on the list for shipping this april maybe late april or early May.

 

Guys what do you use to OC your cards??
Rivatuner or What?

I am nt interested in permanently OC cards only when required, So no BIOS ing for me.

Thanks

 

SiliconChip you can try nTune. I didn't tried it, because I do it directly from BIOS, but I saw in one site they have used it for OC.

RayanMX, I saw your clocks of your GPU. Just to know, always keep the ratio between shader clock and core clock.This is for maximum stability. For your GPU, and I think for all 9 series, this ratio is 2.5. See your default clocks:
core: 530
shaders: 1325
Divide 1325 to 530 = 2.5.
So if you use 620MHz core clock, then your shader clock must be 620x2.5=1550MHz.

 

Ok, so with RayanMX settings I got 9854 points. Thats running Windows 7 64 bit as well. Also i went with the newest DOX drivers he just put out for WIN 7. Thanks for doing all the testing RayanMX!

ok, here's all the results...
9854 with turbo @ 20% and RayanMX settings
8899 with turbo @ 20%
8534 with 2.4ghz

All using DOX new drivers here - http://www.laptopvideo2go.com/forum/index.php?showtopic=24003

Also, its an improvement over the newest official Nvidia drivers

 

I sometimes game all day on this gt627 with turbo on, have never experienced a heat related game crash or lockup. (Owner since early feb.)Sometimes the heat blasting on my mouse hand from the vent is a bit distracting though. I do wonder why the right palmrest gets so warm even on minimal usage, rest of the rig stays cool.

 

I was curious to know if the GT627 has a hidden bios option like the 1722 does, ALT + Insert? Anyone try this?

 

Tried the ALT + Insert and nothing.....

 

It would be under the advanced tab in the bios.

 

What voltage did you need for it to be a gts?

Guys, do you think I could take a gts and flash it to a gs instead? If abishai couldn't get the voltage to increase, maybe it's because the notebook can't power a gts....

Has anyone successfully flash their 9800m gs to a gts?

 

I flashed my bios with little problem. Just follow the directions from other links. One tip though is "nvflash -6 newbios.rom" this will allow you to avoid the " PCI Subsystem ID does not match " error.
