Unlocked Nvidia-Dell Video BIOS! Overclock your 17inch notebook Videocards! - Page 18

Can somebody give me a detailed instruction on how to create roms and create a bootable disc with the roms on it and all the programs that are supposed to be used? I wasted a whole weekend attempting but i failed miserably and lost about 20 cds in the process. Any help would be very appreciated.

I was just about to post about the clocks/power usage thing until I saw Kraziepop's post; for anyone that thinks otherwise, what he posted is a well established fact and he explained it very concisely and clearly.

The only thing I will add is that the increase in temps you get when increasing clocks is really not a linear curve on most graphics cards (ie, the difference between 535 and 600 may only be a small amount like 4 C, while going from 600 to 602 may give a 6-7 C increase). This is due in large part to how most modern GPU's are structured today, aka, different sections of the core (ROP shaders, vertex shaders) will run at different frequencies depending on what the delta (or offset) is set to in the BIOS. This is also why increases in frequency are not always linear to performance increases.

To simplify it (and this is just a made up example to illustrate):

Core at 400 = ROP shaders at 375
Core at 415 = ROP shaders still at 375
Core at 416 = ROP shaders at 410 thus demanding more power than that 1MHz increase would be expected to cause.

Anyway, back on topic.

Something I've been wondering about is if it has been confirmed that with the current unlocked BIOS clocks stay at the full power 3D setting when on battery? If so, what changed? I for one for one like to get at least an hour out of my 6-cell.

Download a burning program like CDBurneXP Pro 3. Download the .iso image from the first post in this thread. Open CDBurnerXP Pro 3. Go File/Write Disc from ISO File. Select JLMOD.ISO. Make sure you select 'Finalize Disc' and then hit 'Write Disc'.

What i want to know is how to create my own roms, make it an ISO, and put it on a bootable disc. Thanx for the hlep anyway brownstone. Can anyone guide me through this.

Nice post KP twas getting a bit heated there, for nowt

Kind of off subject a bit, but a good electrical analogy to water
Voltage is like water pressure and current is like the flow rate

Ultracow (nice handle!)

Powermiser works for me for juan's software flash ontop of these drivers with this card. Prior to this the older style bios flash had this card stuck in 3d. I've verified this using rivatuner and my battery life

I'm wondering what temps you guys are hitting with the modded bioses.
I've flashed my card down to 1.05v for 3d clocks (600/800) and I'm hitting 92 degrees max when playing Rainbow Six Vegas...
It seems like my temps are more or less the same as the 1.24v I was running on previously.
In addition, my VID never seems to switch from 07.

Hey ZX,

Do you mean that it works properly using his newest BIOS releases? Or am I missing something here?

Thanks for the help!

Ok, hoping someone can help me here.
I have flashed my dual pipe 7900gs to a gtx using the 790GTXUO.rom and now my VID is stuck at VID7 (1.24v) all the time.

Anyone have any ideas on how to fix this so it will drop to 1.0v when using 2D and battery?

edit.... OK, after spending the last few hours trying to get this to work correctly (10 different flashes, 20 different driver reloads etc...) I have given up.
I went back to my original modded 7900gs@610core 1200mem and everything is working like it should again (I can see it change from my VID7 (which is my 1v on this rom) to VID4 (my 1.24v) with rivatuner and when I unplug the AC, I get my ~3hours battery life again (while with the firmwares listed in this thread I only got ~2.15 hours battery life).

Just my experiences but I am curious about what others have noticed with theirs.

I noticed the same. Comparing the temperatures I get during 3DMark05 at 1.05v and 1.24v I got exactly the same results. Obviously the 3d-voltage is still at 1.24v, even with nibitor showing 1.05v.

So you better choose between 1.0v for the non-demanding applications and change to 1.24v if you need more performance.

Hi

Last night I flashed the 7900gs in my Dell Inspiron 9400 to the 790GSUOV.ROM, which is Frequencies Unlocked and Memory Optimised as well as voltage at 1.24v.

I used ATi tool to overclock to 550mhz on Core and 1400mhz on Memory. I was very pleased with results with 3dmark05 hitting 8500 and its a good 2000+ score increase over the stock speeds.

The temps were good idle was 56 degrees on the card and after 5mins on ATi tools the temperature was going no higher than 82 degrees.

However I'd really like to know is... will using these settings have a long term effect on the 7900gs and could this considerably shorten the life of the graphics card.

Deffi:
With increased temperatures, there is always an increased probability of a shortened lifespan with the graphics card.
For realistic temperature measurement, leave ATi-Tool on for about an hour...
It takes roughly 30 minutes for your card to hit its maximum temperatures.
Once you see the max temp. you can decide whether it's worth the risk for you to OC. Generally, anything in the 80's range is considered relatively safe.

As for the temperature and VID problem, I wonder how we could get the VIDS to switch.
I'm currently running 0.8v for 2d, 0.9v for 3d, and 1.05v for 3d. After thorough testing, I'm not seeing any noticeable decrease or increase in temperatures.
Krayziepop said his testing revealed that the changing of the voltage values corresponding to each VID worked to decrease his overall temps...perhaps it's a driver issue?
I've tried 84.63 drivers, 84.69 dell drivers, 91.47 mobileforce drivers, and 92.77 mobileforce drivers...and none seem to change the VIDS whatsoever.

You cannot simply put in a voltage value and expect to get it. There are only 2 voltages supported by that bios as far as I'm aware, and those are 1.0 volts and 1.24 volts. ANY value you place in the bios will not make a difference. Heck, try 1.3 volts and it will not change anything. If the bios does not recognize a value you put in (and it won't recognize 1.05), then it simply reverts to a known value, which is either 1.0 or 1.24 volts. There is clearly a difference between 1.0 and 1.24, but I don't think it's possible to get anything in between (simply because the bios doesn't recognize those values).

You have to use 3 VIDs to get it to work.

I use

VID3 = 0.95V
VID7 = 1.0V
VID4 = 1.1V

Remember the VIDs need to hav different Voltages.

Me and som other people in this forum dont agree with that. I have tried VID 3 = 0.95v VID 7 = 1.0v VID 4 = 1.24v Resulted in peek temps at 87c but the powerbrick was almost smoking after 2h gaming. Vent down to VID4 = 1.1v and now GPU temp peek att 83 and powerbrick stays cool. If it went back to 1.0v why would i get higher temps than the original GS bios and lower than the 1.24v bios?

I have my VIDS set at 3, 7, and 4 /w the voltages @ 0.8, 0.9, and 1.05 respectively. I'm still hitting 92 degrees peak temperatures when playing stressful games like R6:Vegas.
I've done everything from polishing my heatsink and applying a thin coating of AS5 many times over...and still my temps stay the same.
Do the VIDS really change anyways? I monitor Rivatuner constantly, and my VIDS simply stick to 07 all the time...

Another thing that's interesting to note, is that i've been able to clock my card @ speeds of up to 630/800 on just 1.05v...which it may or may not be actually using.

Nero should be fine , or ? (should i use finalize disc in Nero to ?) then after flashing. can i use nvidia controll panel to OC. (forceware with modded INF) i also want to make 2 different profiles with rivatuner, it should work ? maybe a noob qeustion. at step 4 ; "type nvflash xxxxxxxx.ROM. (should i type EX. 790GSUOV or 790UOV.ROM. ? )

Nero is fine, just select 'Burn Image'. You also shouldn't need to finalize it, that way you can always add to the .rom list later if you feel like it.

You can change clock settings in the control panel, as long as that INF unlocked the OC window (Like coolbits does)

Not sure about the Rivatuner profiles, I don't use it.

It should look like

nvflash 790GSUOV.ROM

Or, if you are going to use a GTX bios:

nvflash -4 -5 -6 RomName.ROM

I've used Nero before as mentioned above and works great. I found with other .iso files and CD-R that I had to 'finalize disc' to get laptop to boot from cd. Probably different with CD-RW of course.

OC'ing the 7900gtx with the nv control panel, i will BSOD when booting into windows with certain video drivers. So I OC using rivatuner instead. Haven't tried profiles yet.

Yea Rasken, this is basically how I have my modded 7900GS rom set up *except 1.24v on vid4. Maybe I should edit the OC unlocked bios's on this thread to have the same VID's as my custom one and see how they fair. I was just getting a bit tired of reloading over and over last night and decided to give it a rest. oh, and one more thing Rasken... in which order do you have your VID's listed within the bios? As in the order you listed them here, or VID4, 7, 3 etc... Just want to try some things out. TIA D.
