Flashable GTX 680s being sold in the UK, super cheap!

Hi again - sorry to monopolise your evening,

OK - I've done the firmware flash - the only difference I had was that I had to press Y a couple of times to confirm that I wanted to overwrite - but I now have boot screens and a PCI Cards tab that displays 5.0GT/s.

I noticed that you were running CUDA-Z v0.6 and I had d/l v0.7 - I grabbed the same v0.6 as yourself and got it running - however I notice that my memory section appear to show a much lower set of memory copy numbers that your screen shot (I'm running a Mac Pro 3,1 if that makes any odds). Any ideas why this may be?



All the best,

Moley

Sorry, nothing concrete about the memory copy data.

However, my Mac Pro is a 4,1/5,1 Hybrid. The memory controller is supposed to be significantly improved over the earlier variants. Maybe that's what you're seeing?
 
Maybe thats what it is then.

Interestingly I ran the Windows Experience Index and with the original PNY rom I got a graphics score of 7.9 but after flashing to the evga firmware i only get a score of 6.0 for some reason.

I flashed back to the PNY rom and am back to an Experience Index of 7.9 for graphics.
 
When you flashed to the evga rom did you get any messages asking you to press Y to confirm as there were board differences (i think that was the message)?
 
No worries - thanks very much for all your help so far; very much appreciated.

I will open another thread re the WEI differences and memory copy differences and see if anyone else has any ideas that would help us all.

Thanks again,

moley

Quick update:

I just did a dry run with nvflash and can confirm that there are 2 dialogs that require a "y" response.

Hi,

I managed to get the last one of those 680's and it's due for delivery today, I have a question about powering both my graphics cards during the flash, I'll be flashing it in my MP 8 core 2009 which currently has an ATI 4870 which requires two 6 pin connectors the same as the 680. Is it possible to run both cards with a single 6 pin cable for the flash?

I only had my GTX680 in the Mac Pro when I did the flash.

Thanks for the confirmation, Cal6n.

I *think* I've worked out my issue with the WEI score - I had installed the nVida 314 driver and with that driver installed my graphics score alternated between 6.0 and 7.9 depending on which ROM I was running.

I then d/l the beta 320 driver from the EVGA website and now it seems I get 7.9 graphics with the EVGA-flash'd firmware, so fingers crossed it is all good on that front. Interestingly, I ran the Heaven Unigine benchmark with both graphics scores and there was only 2-3FPS differences between the 6.0 and 7.9 WEI graphics scores.

Just need to find out about the memory copy differences between your set-up and mine now :)

Thanks again for your help last night.

Cheers,

Moley
 
Hi,

Thanks for the instructions on flashing the GTX680. I ordered the EVGA GTX680, part # 02G-P4-2680 from Newegg last week. It arrives today and Im going to flash it tonight. I'll let you know how I get on.

Best Regards,

Mark
 
Followed cal6n's instructions to the letter and now I have boot screen!

Now in OS X and trying some 3d apps to tax the card.
 
So far so good - ran some basic steam apps, WoW and Starcraft 2 and didnt see any issues. Of course none of these would tax my previous card (EVGA Geforce GTX285), but Im not seeing any artifacts or lockups with the new card either, so its a good sign.
