So we want to use the 79GTXUNV.ROM not the 79GTXUOV.ROM? just want to do it right the first time and all.

Thanks.

You need to use 79GTXUOV.rom.
Yesterday i told you this was going to happen...

.

Here is the video that works as proof of concept!

Have fun!

Really the choice is up to you which file you decide to use. I use the GTX BIOS that has NOT been memory latency 'optimized'. The stock GTX latencies are the same as the latencies he had posted about in the other thread so really there should be no difference at all between the 79GTXUNV.rom and the 79GTXUOV.rom. At least no difference that I have found. I can safely clock my memory to 825Mhz without artifacting with the stock unlocked BIOS. So I for one will be sticking with it.

What format does the D have to be in? I unpacked the .iso and burned it onto a cd but when I restarted and did the dvd boot, nothing happened, it just loaded to windows.

Also, is this a flash to the bios or a boot load? So if something happens, will I need an original copy of the bios?

Hmmm, I may actually give this a shot (as I found the sweet spot with the GS bios so was not wanting to reflash a couple dozen times to test the gtx bios).

nice work....although I cant use it...I'm running Vista, and the nVidia Control Panel still isn't all there, including the frequency settings....bummer...

dougadamsfan · 12-22-2006, 09:09 AM

Does this hack support manipulating voltages via software as well (I don't think you can do this in cool bits but I haven't fully explored all the options in ATI tool)? Or would we need to alter the rom file if we wanted to change/downclock the voltage? I'm very excited about this.

EDIT** Nevermind, if I use the "memory optimized" rom then the latency issues that prohibit the 7900 GS from hitting high memory clocks become nonexistant and the voltage is still at 1 V.

Hi,

Before I make mistakes, can I use these GTX bioses on a 7900GS?

Thanks;

Rudrood

dougadamsfan · 12-22-2006, 10:01 AM

yes

Good Job on unlocking the vbios..

Now the question is who's card/systems going to first die first .. Not to be the downer to the this good news but there are reasons the locks are in the vbios.

Now back to the celebrating.

Enjoy!

pdonket · 12-22-2006, 10:24 AM

yeah....I'm thinking I'll keep mine at stock clocks and dig this thread up if my system ever feels too held back

I dunno, for me I don't see a real reason to jack up the clocks especially when the 7900GS is a great card in the first place. To each his own

Krayziepop · 12-22-2006, 11:13 AM

Considering that Dell is the only company that locks out clockspeed via the BIOS, I am not really too concerned. Now you can overclock it just like any other 'normal' graphics adapter. Besides that, I have overclocked EVERY video card I have ever owned. Never once have I had one fail due to my overclocking carelessness. Dell locks out those features for two main reasons, one is that they can make a whole lot more money by selling a 7900GS and a 7900GTX. Stock GTX speeds alone are enough to convince most people that they would need that card to game the best on... Take away the BIOS lock and your customers will realize that all they need to do is overclock the hell out of the low end card to acheive the same results as buying the ridiculously expensive upgrade...

Number 2 would be of course to prevent heat related failures. These things don't have much room to breathe as it is, and pumping the clockspeeds up will of course change the heating pattern significantly. Of course, most people that are willing to overclock their card in the first place already know to keep an eye on temperatures.

I say just go for it. If anything, you can easily flash back later if you so choose to want the restrictions back. No biggie really, but if you like to tweak then why not? I mean the fact that I was able to gain an additional 1200 points in 3dMark06 shows that these things are severely hampered by the low specs Dell ships them with...

sergiop · 12-22-2006, 11:19 AM

completely agree with you.

When I extract the ISO file to a CD, do I just extract it directly and burn it? I tried doing that on my 1705 and when I reboot and select to boot from the disc drive, it just goes straight into windows. What am I doing wrong?

Deceptikon · 12-22-2006, 12:37 PM

You need to use a program like Nero or Alcohol 120%

Then choose 'Burn Image' and point it to the .iso file

No need to extract anything.
