Very nice.

Is there some kind of hardlock on 1150mhz for the max boost deeper in the bios/card somewhere? Since everything works just as it should up till there, set anything above that and it just stays there instead.

I think this is a bug.

I had set mine using OC Guru (afterburner wasn't working right) to +80 but the clock speed was stuck on 1150.

Any other clock above didn't change the 1150, and/or crashed. Temps were good. Power limit was maxed, voltage was 1.2v

Just restarted OC Guru after I saved the profile, correct reading of 1267 now.

Same issue with Afterburner.

The problem for me isn't that it can't reach my max oc "at all", if I play more demanding games it gets there.
The problem is that it doesn't always go to the max mhz, which I want it to do. No matter the load on the card! Even if the driver sees "oh ok low load don't have to go to max mhz" it obviously should, since I'm getting subpar fps :/ This is of course also partly a problem with the game(s), but they really shouldn't add this crap without having a workaround, since if it fails, you're screwed. Unless you want to mix around with stuff like K-boost, but I'd rather have it as simple as possible.
They really should add an option for enthusiasts to completely disable boost, go to max mhz, configurable per application.. then everyone else wouldn't be affected. Simple!

This wont happen as boost is dependent on volts/temps etc
You could try using EVGA precision and setting it to a frame rate that's higher then you can achieve , then i'd think it will sit at the max clock while playing?

Just received a new sealed EVGA 780 SC that wouldn't play nice with the one I already had. It has a BIOS sticker on the back labeled with revision 80.80.21.00.80. I took my main card out and booted up fine with the new card only installed. When I try to backup the BIOS on the new card with GPU-Z it crashes and says BIOS flashing is not supported by this device. What am I doing wrong? biggrin.gif

You need to get the latest version of NVFlash and use that to back up the VBIOS.

To save your BIOS, open up a command prompt and in the command prompt go to the directory where you have NVFlash. For ease of use I always just put it in C:\Classified (since I have a 780 Classy):

1st step
Nvflash --protectoff
(This will disable the bios protection in order to save or flash a bios)

2nd step
Nvflash --save call.it.what.you.want.rom
(This will save the stock bios)

Don't use GPU-Z to save bios, some versions may save your bios corrupted or may not work as you found out.

Be cognizant of whether your cards are A1 or B1. You don't want to put the B1 BIOS on an A1 card.

Thanks sooo much for the response. Is it safe to assume GPU-Z 0.7.7 is correct that both GPUs are B1?

OK so I tried what seemed like the latest version of NVflash from Guru3d, same crash when I tried --protectoff.
Then I tried the latest version of nvflash listed from TechPowerUp: v5.134.0.1 and it said it was successful removing EEPROM write protection. But when I tried --save filename.rom it gave me this:
Code:
Identifying EEPROM...
EEPROM ID (C8, 4012) : GD GD25Q20 2.7-3.6V 2048x1S, page
Reading adapter firmware image...

ERROR: PCI Block chain corrupted - PCI Expansion ROM Header not found - Get UEFISupport() failed

I also got that from version 5.134. I believe that there's a verson 5.142 that will work.

Here you go, this should do the trick:

So...like turning off turbo clock on intel chips?
