Official 7900gs Overclocking Thread

thanx i found your post a few back......i've got mine down to 1.06v and perfectly stable.....been running this way the last few days and i've got mine set at 550/550 (haven't found much gains in setting the memory much higher)

 

Are you sure that this will work on my card? Can you give me some more details on this?

 

go to guru3d.com and download Nvflash 5.50 i think it is and nibitor 3.1
if you have an external floppy it is easy as all you have to do is format a floppy disk and windows can make it bootable for you. there's some instructions on the website as well on how to use these 2 programs. Basically what u want to do first is create a backup of your bios using Nvflash and then you use Nibitor to edit the bios. Just make sure you know what you're doing before changing any settings and flashing your card!! And if you do it right it will work on your card......it's exactly the same bios version as mine. Before I played with mine i did some research first on this forum and also laptopvideo2go's forum.....there's lots of info to be had for overclocking the go 7900 gs

 

Did you do this on YOUR card? Do you have a dell? If so what model? Ive been hearing things about these new cards and they dont like to have the bios's flashed either. I just want to make sure I dont **** up my new laptop.

 

read a few posts back and there should be the new dell bios flashes for newer versions.

 

Yes i did this on my card and it's a dell inspiron 9400 with geforce go 7900 gs rev 02 (identical to your card). As long as you edit a rev 02 bios then you're ok...just don't use one of those gtx or gsx roms!

 

I used NiBitor this afternoon and made a bunch of bios files then flashed the bios with nvflash and tested each one for stability. All went great, I would say this is the EASIEST way to play with your video card. Forget the premade roms and make one that WILL work right from your own video cards bios. Im at my final setting now of 460/560 @1v. ATItool has been running for 30 mins with no artifacts and the GPU temp didnt go above 66 degrees. Ill get back with a 3dmark05 score in a bit.

BTW its a Dell XPS M1710 laptop built like 2 weeks ago with the 7900gs GO card in it.

Now im GLAD that I didnt pay the extra 400$ go have the 7950gtx card put in.

 

7564 3d marks in 3d mark 05 with the above settings. I just made a new bios file after reading your above post. 550/575 @1.1 volts ill post back with 3dmark 05 scores, I just want over 8000 and ill stop o/c'n. LOL

 

Well im officially done overclocking this card. Ive reached a stable 575/575 @1.10 volts and my 3dmark 05 score is 8491 which is the same as a 7900GTX scores.

Pretty damn good for a free mod and a few afternoons worth of research.

The card scored 6100 when it was stock clocked. Thats an amazing improvement. I could probably go higher but i like the fact that my GPU/mem speed are the same at 575.

Also 1.24 volts is not needed. Stable high speeds can be achieved with much lower voltages as i have proved here.

 

Glad to hear of your successful o/c'ing!!
I'm still running mine at 550/550 at 1.06v.....1.24v is definitely overkill and only necessary if you're doing some insane overclocking (also insane temps).

thc...don't forget to add 8C if you're taking your temps from atitool. Personally i like using i8kfangui for monitoring my temps and you can include the 8C temp offset......also great for charting temps while playing games.....bc after you exit a game the gpu temp drops rapidly.

 

sounds like you're using the stock dell vista drivers?? go to laptopvideo2go.com and get the latest modded forceware drivers.....my 3dmark scores went up almost 10% once i upgraded to 101.41!!

 

Newbie question: How would I check what rev my e1705 is? Can I see it in the Nibitor BIOS editor? I'm totally new to overclocking, and this topic is a bit overwhelming

 

Hi there!

I feel the same about the 1.24 volts being an overkill. Can you please upload your rom file somewhere?

 

Hi there! I feel the same about 1.24 volts being too much. Can you upload your ROM file somewhere so I could download it?

 

Whats up guys, thanks for all the tips. Willystylz and THC420, followed both your spec ranges. Used all the same programs, etc. And got wonderful results.

I set mine to 550/550 with 1.08v (decided to just give it an extra 2v's of room).

Initial 3dMark05 score - 6500
New score - 8500

And after a short amount of usage heat peaked at 70 degrees with 8 degree compensation.

I decided against pushing it any further. 575/575 and 1.1v only got me 8800. And I've read guys topping out at 9300 at 600/800. Not worth it. As I mentioned on another forum, the point is to unlock the potential of the card not drive it to full capacity.

Flickshot, you can design your own bios roms by downloading nibitor. In the settings file menu, or something like that, you can set new voltage amounts.

All the best guys, and thanks for the tips. When I got the system it was just below my expectations when it came to my desired results. Now its gellin' nicely.

 

Alright im back again with my final o/c settings and the newest drivers from Nvidias site. I ran 3dmark all night the first night, then atitool the 2nd night. Completely stable at 580/580 @ 1.11v. My score in 3dmark 05 is 8921 FRIGGGIN SWEET! during gaming my temp never goes above 71 degrees. THIS IS ON A/C POWER.


Heres the best part. As most of you would notice the grapics performace is **** on battery. I set the speeds for the card when on battery to 400/500@ .9v. Stock they are 200/300 @1v. I score 5200 in 3d mark05 when running on battery and my battery lasts just as long if not longer then before because its running at .9v instead of 1. Its completly stable at .9v at these speeds, saving me significant battery. I get an hour and a half playing battlefield 2 like this

BTW my 3dmark score on battery before this mod was a hurtin 2900.

 

This thread really died. Thanks to the 1 person who helped me (willyStylz). All the other useless 3dmark whores thanks for nothin'.

 

sorry, we're all too busy gaming with our tweaked 7900gs' to really pay attention anymore. Besides, a lot of the questions that usually come up here were usually asked and answered a couple of posts back....usually.

 

HAHAHAHA! Oblivion's got me sucked in........too busy admiring the gorgeous graphics and going gaga over the buttery framerates!

 

Will i get a higher score running the res at 1280x800 rather than 1280x 1024.

I'm assuming yes but i would like some clarifications

As it is

Core 448
Mem 577

Netted me

3dmark06 4031
3dmark05 7500

Are these scores good, bad?

Would volt modding to 1.24 see a score improvement?

I wanna push the core farther but does that require volt modding?

 

Yes running at 1280x800 will get you a slightly higher score.....there's just less pixels.

I had similiar results when my card was close to those settings.

Volt modding alone won't affect the performance......it only allows you to use much higher gpu/memory clocks.

As we've proven in this thread 1.24v is overkill. Depending how far you wanna go you should only need to up the voltage to the 1.05 -> 1.1 range. For example i'm running mine at 550/550 at only 1.05v.......i can up the voltage a bit more and achieve higher clocks but at the expense of higher temps. It's all about where you're comfortable on going.

 

Willy is right, you get higher scores with 1280x800. As a rule of thumb, always try to run 3dmark using 1280x 1024 unless your screen does not let you, that way you don't get inflated values. All you should need is 1.05 volts (some have even gone lower)as you can easily come near or even break the 5k barrier on 3dmark06 (@1280x1024).

That being said, 3d scores aren't important. Only try to overclock until you feel comfortable running smooth frame rates in-game; an extra hundred points in 3dmark isn't going to make a noticeable difference when you're playing oblivion or F.E.A.R. or whatever. Just watch your temps, and remember to add the 8 degrees offset when using ik8fan.

edit: tip: don't use Oblivion to benchmark your in-game temps; it doesn't quite heat up your card like F.E.A.R, COH, and other games do. I'm not really sure why this is, but my guess is that Oblivion is so poorly coded that it does not use all of your card's resources to its full extent, thus the card never really works as hard as it should.

 

I recently bought a Dell E1705 (April 14th to be exact) with these stats;

Intel® Core™ 2 Duo T7200 (2.00GHz, 4MB L2 Cache, 667 MHz FSB)
17 inch Wide Screen XGA+ Display
2GB Shared Dual Channel DDR2 SDRAM at 667MHz
100GB 7200RPM SATA Hard Drive

And of course, the Nvidia Geforce Go 7900 GS


After updating the drivers I got all the way upto 3768 in 3dmark06

My desktop gets about 4100, I'd like to excede this. Perhaps something in the range of 4400, 5500+ SAFELY. This machine was built to replace my desktop mostly, but that doesn't mean I can afford it dying on me.

I'm really new to all of this, but the article on stormlifter seems to be almost a year old at this point. I also saw that some users that bought laptops with the same card much later got ones with a different bios on them, which were bricked upon modification. Thats a major no.

So I'll keep my questions briefer than my post.

Will the bios on stormlifter's site brick my card or how can I tell?

Is there a way to do this from windows at all or that doesn't suck?

Can I underclock to integrated card-like levels and up my battery life?

Can you reccomend me a setting that will get me into that 3dmark06 score range I mentioned earlier?

I'm not familiar with having to use a fan control program. Can you reccomend one and some settings to go with it?

Thanks in advance!

 

I recently bought an Inspiron E1705 (April 14)

After updating the graphics drivers I got up to a 3dmark06 upto 3768.

I'd like for this machine to compete and excede what my desktop regularly scores at, 4100. (Something in the 4500-5500 range) Mostly so that I could feel comfortable with possibly selling my desktop or putting it in storage.

It didn't take me long to find stormlifter's original article.
After reading some of the comments I noticed one user with a newer laptop experienced a bricked card trying to use this bios hack. That would suck.

Things I'd like to run with uber or decent settings
City of Villains/City Of Heroes
FEAR (Halfuber, I can't even uber on my desktop)
STALKER
Command And Conquer 3



Also, I'm running Vista

So I'm going to ask the following questions;

Will this bios flash brick my card or how can I tell?

What is a good file to use to get the scores or performance I mentioned?

Is that kind of performance even safely possible?

Can I underclock my card to the same level as an integrated card (for example) for more battery life? (You know for stuff like Word, Illustrator, and Photoshop for when I'm working or surfing and don't need ULTRA GAMING mode)

I am not that familiar with fan control programs or fan control in general. Can someone point me to a good program, and a basic idea of how settings work. Maybe some good ballpark settings?

Thanks in advance!

 

Sorry for double post. It was late and I used quick reply both times.

 

Protelis...

1)Do not use Stormlifters roms......u will likely have the newer rev 02 card and therefore you'll want to use nvflash to create a backup of your bios and then use Nibitor to edit the bios.......do some research before u do this so u know what you're doing and lessen the chances of screwing something up

2)not sure what u mean by "what is a good file to use"

3)Myself and many others will say that it is safe to achieve 3dmark06 scores of 4500-5000......some ppl will say that we will burn out our gpu (i've yet to hear of anyone doing this on a 7900 gs......the only ones that screw up their cards are the ones that don't know what they're doing when they go to flash their bios)

4)Yes I guess u can underclock your card......but in 2d mode it's already seriously underclocked.....some ppl will go to the point of even lowering their 2d voltage to 0.9v or slightly less to achieve a bit more battery life

5)I use I8Kfangui.....but only to monitor my temps.....from my experience this program will not lower your maximum load temps, only prolong the temps from getting to peak

Hopefully this helps!!!

 

I got the rev2 aswhile. However everything i try to write firmware to disk i get the message that I/O error cannot wirte test.rom.
I am using my mp3 player, along with a dos boot cd.
any help please.

 

Can you create an image that automatically flashes a rom file to your laptop?

You could get a handful of those 64mb flash drives for $5 and put a different setting on each of them, then just restart and have it boot from the drive.

ex.
Stock
Overclocked
Work-mode

Does this work on regular desktop machines?

I ask because if I screw up I could run it on my PC step by step and duplicate for the laptop with my stock rom file.

Thanks for all your help guys.

 

I'm not too familiar with using flash drives or mp3 players as boot disks. For all my flashes i've used an external floppy and had windows format my floppy as a dos boot disk. After I configure my bios with nibitor i just put in the floppy and reboot.

Every time i use the command "NVFLASH -4 -5 -6 *****.ROM"

 

When flashing bios u need to boot into DOS......then once done u reboot as normal into windows. And yeah if u have an older desktop that's a good place to practice. Just make sure u make a backup or find a proper copy of your desktop gpu bios to use.

 

Thx for the quick reply, as I said I only use the mp3 as a storage place for the rom which i then have to edit. i been using a dos boot cd. however it seems nvflash cannt write to the mp3 and i dunno y, after all i could access and del files from it in dos. if that does not work, i am think of using someone else's rom. can anyone with rev 2 upload their rom and write all the numbers associated with it, so i dunnt flash the wrong one lol. thanks

 

i see u talk about 1.05v, 1.06v, 1.08v voltages, but how i set this voltages in nibitor for geforce go 7900 gs ????

My nibitor have only 1.00 v and 1.24 v

Thanks ...

 

Anyone figured out how to do this on the NX860? I think the BIOS update locked my GPU from ever overclocking again. Man, I had some good clocks prior to this...oh, well.

 

but u dont know how to set voltages ???

 

use the voltage table editor within nibitor

 

005.071.022.016.013.000 is the cards bios version. It is a rev2 right?
Can some one update the stock bios for it please. cannt save it to my mp3 with nvflash, donnt kno y.

 

here's a discussion we had a few posts back regarding the steps to adjust the voltages in nibitor: http://forum.notebookreview.com/showthread.php?t=64385&page=36

 

go to mvktech.net

that looks like a rev 1 card

 

can anyone help ... i have geforce go 7900 GS and i oc this to GTX 500 / 600 1.24. On windows xp riva tuner and ati tool show temperature +/- 62 to 66 C and on game show 73 to 87 C
but now i install windows vista ultimate and riva tuner show +/- 57 C and max 76 C on game

what the correct temp??? on vista or XP ?

 

how do u actually check if its a rev1 or rev2?

 

my original card is go 7900 gs rev1

now it is flashed whit 7900 GTX
bios name is v500c600.rom
core = 500
mem = 600
3d volt = 1.24

 

I'm running 500 core 1100 memory, and I'm getting 4500ish in 3dmark06.

My score is probably a little inflated by my processor being 2ghz, though.

I'm peaking at about 70c with the 8c offset and everything. This is after about an hour with FEAR with the laptop sitting directly on my LAP btw. City of Heroes performance is ALOT better, but still crap. It's probably just a Vista issue. I might dual boot XP to see if I get better speeds. I haven't tried any Steam games out of laziness. Tomorrow I'm going to try C&C3.


I can't seem to go any higher without artifacting. I've noticed some people upvolting their GPU to things other than 1 or 1.24. 1.24 seems like waaay too much for me. I read that someone was getting great boosts with a mod of 1.05 but I can't seem to figure out how to set it.

Do I need a "GSX" bios? If I get the one yolga posted a year ago will it work with my NEWER e1705?

If I can get the volt mod to work it seems like I can crank a 300-400 more into my 3dmark score.

(FYI, right now I'm scoring about 5-10% higher in SM2.0 and SM3.0 than my stock clocked 7800GTX (runs too hot to overclock because of inefficient cooling) on my desktop. I'd like to go for another 10-20% if at all possible)

 

plz anyone help-me... my gpu temp is +/- 64 no game ... and max 88 in game
why my noot give hight gpu temps ???

Set your laptop on a level surface that allows adequate clearance of the bottom.

If not, well, I don't think 88 is too dangerous but it's definately approaching dangerous.

If you have the "GSX" bios thing going, would you mind me asking how old your laptop is? If it's a newer one like mine I'd be interested in knowing what revision your card is if you know. I have an emergency backup disk I've confirmed that works, I just don't want to push my luck flashing bios' I know nothing about.

You might also try stepping down your voltage with nibitor. I've seen alot of people get some really good performance at 1.05 and 1.06 volts. 1.24 seems excessive.

 

go to display settings and then to advanced.......your bios version info should be displayed.....vista reads mine as 5.71.22.28.1 which is rev 2

 

max of 88 C in a game is pretty high....depends if you're including the 8C offset

 

Protellis.....to up your coltage u must load your rom in nibitor and use the voltage table editor.......with nibitor v3.1 atleast, if u click on the '?' the help file comes up.....that helped me when i was figurin things out..........also mvktech or guru3d has a guide on how to use nibitor

 

I looked at it, but I only seem to have the choice of 1v and 1.24.

 

Same here, I have the latest version and the checkbox for extended voltage seems to b grey and I can not click it.
Anyone have a fix?

 

In the voltage table editor under "Label" and beside "Entry 2" click on the adjacent box.......a list of voltages should appear.........that's where u basically select the one u want.....then go under the voltages section back in the main screen and you should be able to change between 1v and your new selected voltage for 3D mode.
