Any sign of the 560 bios to try on a 460 yet?? - Page 7  

post #61 of 331
Thread Starter 
Ive just been thinking. Theres a fair chance nvidia has enginnered the 560 bios to not allow the extra shaders to unlock on the 460, possibly through some pieice of insignificant code. Maybe if someone could take parts of the 560 bios and mesh it into the 460 bios. If thats even possible.

Anybody speak bios?

Of course it wouldn't unlock shaders. Again, the 460 and 560 are completely different GPU's.

And no, flashing an 8800GT to a 9800GT works fine, seeing as they are IDENTICAL rebrands. They're both G92, they're both the same shaders, they're both the same clock speeds, oh and they're both the same die even.

Fine, it would be like trying to flash a 9800GTX into a GTX280 (both high end cards, just a different generation). Or a 9800GX2 into a GTX295. It might work, but its not going to do anything at all.

I think that implies you are certain. Look, anyway you look at at, the 460 and 560 are technically the same GPU, they are pin to pin compatible, whether nvidia laser cut the die or locked the core down or did something else to effectively disable it is completely unknown.

What nvidia say might be different to what they do. They said GF114 had improvements but that's a blanket term. Is the the improvement due to using the same die with the extra core unlocked?

Remember that GF104 and GF114 are just names. The fact is that they could be the entire same GPU, due to the fact that the pinout is the same. GPU codename is in the BIOS, is it not? BIOS'es can be edited, hacked and whatnot. Of course, it the GPU itself (or it's metal cap, more precisely) it says GF104 for the 460 or GF114 for the 560. They are just names

All I'm saying is that it could be possible to effectively unlock the "missing" shader cluster on a 460.

Also remember revisions of GPU's. The first revision may or may not have been laser cut, just bios locked, the second revision may or may not be laser cut or bios locked, or vice verca.

You're being very negative about this is all, and it's not helping when people are trying to sort out the facts. Half of the posts in this thread are people saying it can't be done, when in fact it could be possible.

As seen, someone has already tried flashing, while not bricking his card, it didn't unlock anything either. He is also at stock GTX 560 clocks vs. overclocked GTX 460 clocks.

Food for thought: Let's say you have the skill and equipment to desolder a GPU from the board. Let's say you then proceed to flash a GTX 460 to a GTX 560 BIOS, shut down the system, remove the GTX 460 GPU and solder on a GTX 560 one onto the GTX 460 board, then boot with it, would it work?

That question is purely hypothetical.

Off topic: Check out the overclock on my 460



As much as I want to try flashing my 460 with a 560 BIOS, I'm going to wait for more confirmations (or denials) and GPU-Z screenshots.

Now we have concrete results on this topic that a 560ti bios flashed into the 460 bios chip works but the card does not turn into an unlocked 460 but rather it is the same 336 shaders running at frequencies that were programmed in the new bios.

I have two questions:

1. When flashing the new bios, was the default voltage the same as previously? I am not sure how that thing ASIC works but I have the feeling that the bios is setting up the voltage upon the series of GPU. I could be wrong but I think all 460s of one brand and model have the same bios.

2. I tried to flash my 460 directcu yesterday but I could not do it with nvflash. The files from techpowerup are with bin extension. I tried to rename it with rom extension. Is this correct? BTW I am flashing from Windows command prompt.

I noticed that ASUS 460 rom file is 60kb while the 560ti bin/rom file is 64kb so there is a difference. The nvflash -4 -5 -6 xxx.rom does not work and neither does nvflash -5 -6 command.

One thing though. I thought that bin and rom file is the same thing. But when I save the bios from my 460 with GPU-Z the file lenght is 64kb (the bin file). And than when I rename it in Nibitor into rom, the rom file is 60kb. This is weird because it seems like Nibitor is doing some modification to the file when converting from bin to rom. This only reffers to my 460 original bios. The rom file saved with Nibitor works just fine and flashes properly.

And when I try to save the 560ti file in Nibitor from bin to rom, the operation is successful but the file length of the 560ti bios is the same (64kb bin = 64kb rom).

Any help is appreciated.

Unsure on the voltage questions, But my Palit GTX 460 had a default voltage of 1026mv, my XFX one is exactly 1000mv at default, raised slightly to 1025mv with the overlock I posted previously.

What you want to do is save your BIOS with GPU-Z, I think they are .ROM files by default. What you need to do is open the BIOS in NiBiTor and save it as .BIN without editing.

If one 560 BIOS doesn't work, try a different one. Even some BIOS of the same cards from different brands don't play nice sometimes. If it comes as .ROM by default, open the BIOS in NiBiTor as said before and save it as a .BIN file to use with nvflash.

That reminds me, what version of nvflash are you using?

Uh, I am at work now and I do not have it in-front of me but I made sure it is the latest version.

BTW GPU-Z saves files with bin extension and this nvflash for windows works only with rom files. Thanks.

The thing is, and I may be new to Nvidia sure but it's a GPU Nonetheless, why not just overclock the damn thing? Use afterburner to increase your damn voltages and overclock and DONE!

Wow I voted the thread 1 star and it went down to three....

Then HELLO!!!!??? If my 470 can't "unlock" into a 570, what makes you think a 460 can unlock into a 560? Sigh.

People have tried it, it works, but it does nothing. Because a 460 is a 460, and a 560 is a 560. They are different GPU's entirely, just like my 470 is different from a 570.

Have you ever, in the time of writing this thread, realised that:

If the 460 is just a locked down 560,
WHY HAS NOBODY ALREADY FOUND THAT OUT IN THE PAST YEAR!?
Nvidia is a huge company, as if they would release hardware much more powerful than they mean to, don't be an idiot, if you understood anything about computer hardware you would understand that they are different chips.

You wouldn't try and do it if they called the GTX560 a UTQ890 would you!?

Guys, in order to cut the process of assuming whether 460 can be unlocked, please focus to contribute to the topic by sharing your knowledge with nvflash and bios sizes for example, unless someone of the members is nVidia or AMD engineer. Thank you.
